    The road transport sector today is almost exclusively dependent on fossil fuels. Consequently, it will need to face a radical change if it aims to switch from a fossil-based system to a renewable-based system. Even though there are many promising technologies under development, they must also be economically viable to be implemented. This paper studies the economic feasibility of synthesizing natural gas through methanation of carbon dioxide and hydrogen from water electrolysis. It is shown that the main influences for profitability are electricity prices, synthetic natural gas (SNG) selling prices and that the by-products from the process are sold. The base scenario generates a 16% annual return on investment assuming that SNG can be sold at the same price as petrol. A general number based on set conditions was that the SNG must be sold at a price about 2.6 times higher per kWh than when bought in form of electricity. The sensitivity analysis indicates that the running costs weigh more heavily than the yearly investment cost and off-peak production can therefore still be economically profitable with only a moderate reduction of electricity price. The calculations and prices are based on Swedish prerequisites but are applicable to other countries and regions. - Highlights: ► The production cost for synthetic natural gas corresponds to the current biogas price. ► High return on capital if the synthetic natural gas could be sold for the same price as petrol. ► Production can cost-effectively be run off-peak hence electricity is the major cost. ► This study is based on Swedish prerequisites but is applicable on other regions.

  2. Synthetic fuels and fusion

    The decreasing availability of fossil fuels emphasizes the need to develop systems which will produce synthetic fuel to substitute for and supplement the natural supply. An important first step in the synthesis of liquid and gaseous fuels is the production of hydrogen. Thermonuclear fusion offers an inexhaustible source of energy for the production of hydrogen from water. Depending on design, electric generation efficiencies of approx. equal to 40-60% and hydrogen production efficiencies by high temperature electrolysis of approx. equal to 50-70% are projected for fusion reactors using high temperature blankets. Fusion/coal symbiotic systems appear economically promising for the first generation of commercial fusion synfuels plants. Coal production requirements and the environmental effects of large-scale coal usage would be greatly reduced by a fusion/coal system. In the long-term, there could be a gradual transition to an inexhaustible energy system based solely on fusion.

  3. High-temperature gas reactor (HTGR) market assessment, synthetic fuels analysis

    International Nuclear Information System (INIS)

    1980-08-01

    This study is an update of assessments made in TRW's October 1979 assessment of overall high-temperature gas-cooled reactor (HTGR) markets in the future synfuels industry (1985 to 2020). Three additional synfuels processes were assessed. Revised synfuel production forecasts were used. General environmental impacts were assessed. Additional market barriers, such as labor and materials, were researched. Market share estimates were used to consider the percent of markets applicable to the reference HTGR size plant. Eleven HTGR plants under nominal conditions and two under pessimistic assumptions are estimated for selection by 2020. No new HTGR markets were identified in the three additional synfuels processes studied. This reduction in TRW's earlier estimate is a result of later availability of HTGR's (commercial operation in 2008) and delayed build up in the total synfuels estimated markets. Also, a latest date for HTGR capture of a synfuels market could not be established because total markets continue to grow through 2020. If the nominal HTGR synfuels market is realized, just under one million tons of sulfur dioxide effluents and just over one million tons of nitrous oxide effluents will be avoided by 2020. Major barriers to a large synfuels industry discussed in this study include labor, materials, financing, siting, and licensing. Use of the HTGR intensifies these barriers

    Fischer-Tropsch catalysts have been designed, characterized and tested for the selective production of hydrocarbons suitable as synthetic liquid transport fuels from synthesis gas (i.e., by the reduction of carbon monoxide with hydrogen). It was found that hydrocarbons in the middle distillate range, or suitable for conversion to that range, could be produced over several of the new catalyst systems. The various catalysts examined included: (1) synthetic cobalt clays, mainly cobalt chlorites; (2) cobalt hydrotalcites; (3) ruthenium metal supported on rare earth oxides of high surface area; and (4) a novel promoted cobalt catalyst. Active and selective catalysts have been obtained, in each category. With the exception of the clays, reproducibility of catalyst performance has been good. Catalysts in groups 2 and 4 have exhibited very high activity, with long lifetimes and easy regeneration.

  7. Alternate-Fueled Flight: Halophytes, Algae, Bio-, and Synthetic Fuels

    Science.gov (United States)

    Hendricks, R. C.

    2012-01-01

    Synthetic and biomass fueling are now considered to be near-term aviation alternate fueling. The major impediment is a secure sustainable supply of these fuels at reasonable cost. However, biomass fueling raises major concerns related to uses of common food crops and grasses (some also called "weeds") for processing into aviation fuels. These issues are addressed, and then halophytes and algae are shown to be better suited as sources of aerospace fuels and transportation fueling in general. Some of the history related to alternate fuels use is provided as a guideline for current and planned alternate fuels testing (ground and flight) with emphasis on biofuel blends. It is also noted that lessons learned from terrestrial fueling are applicable to space missions. These materials represent an update (to 2009) and additions to the Workshop on Alternate Fueling Sustainable Supply and Halophyte Summit at Twinsburg, Ohio, October 17 to 18, 2007.

    Fuel cells are electrochemical devices that combine hydrogen and oxygen to produce electricity, water, and heat. Unlike batteries, fuel cells continuously generate electricity, as long as a source of fuel is supplied. Moreover, fuel cells do not burn fuel, making the process quiet, pollution-free and two to three times more efficient than combustion. Fuel cell systems can be a truly zero-emission source of electricity, if the hydrogen is produced from non-polluting sources. Global concerns about climate change, energy security, and air pollution are driving demand for fuel cell technology. More than 630 companies and laboratories in the United States are investing $1 billion a year in fuel cells or fuel cell component technologies. This report provides an overview of trends in the fuel cell industry and markets, including product shipments, market development, and corporate performance.

    To assist the Department of Energy, Office of Fuels Conversion (OFC), in implementing the synthetic fuel exemption under the Powerplant and Industrial Fuel Use Act (FUA) of 1978, Resource Consulting Group, Inc. (RCG), has developed a procedure for matching prospective users and producers of synthetic fuel. The matching procedure, which involves a hierarchical screening process, is designed to assist OFC in: locating a supplier for a firm that wishes to obtain a synthetic fuel exemption; determining whether the fuel supplier proposed by a petitioner is technically and economically capable of meeting the petitioner's needs; and assisting the Synthetic Fuels Corporation or a synthetic fuel supplier in evaluating potential markets for synthetic fuel production. A data base is provided in this appendix on proposed and ongoing synthetic fuel production projects to be used in applying the screening procedure. The data base encompasses a total of 212 projects in the seven production technologies.

    1981-01-01

    In the near-term, coal derived synthetic fuels will be used; but in the long-term, resource depletion and environmental effects will mandate synthetic fuels from inexhaustible sources - fission, fusion, and solar. Of the three sources, fusion appears uniquely suited for the efficient production of hydrogen-based fuels, due to its ability to directly generate very high process temperatures (up to approx. 2000 0 C) for water splitting reactions. Fusion-based water splitting reactions include high temperature electrolysis (HTE) of steam, thermochemical cycles, hybrid electrochemical/thermochemical, and direct thermal decomposition. HTE appears to be the simplest and most efficient process with efficiencies of 50 to 70% (fusion to hydrogen chemical energy), depending on process conditions

    1999-01-01

    In Sweden, wood fuels are traditionally used in the Swedish forest products industry and for heating of single-family houses. More recently they are also become established as an energy source for district heating and electricity production. Energy policy, especially the energy taxation system, has favoured wood fuels and other biofuels, mainly for environmental reasons. There is now an established commercial market for wood fuels in the district heating sector, which amounts to 45 PJ and is growing 20 per cent annually. Price levels have been stable in current prices for a decade, mainly because of good access to wood fuels. Price levels are dominated by production costs on a market that is largely governed by the buyer. It is expected that the use of wood fuels will increased in Sweden in the future, which will push a further development of this section on the market and bring about technological changes in the area.

  16. Nuclear Energy and Synthetic Liquid Transportation Fuels

    McDonald, Richard

    2012-10-01

    This talk will propose a plan to combine nuclear reactors with the Fischer-Tropsch (F-T) process to produce synthetic carbon-neutral liquid transportation fuels from sea water. These fuels can be formed from the hydrogen and carbon dioxide in sea water and will burn to water and carbon dioxide in a cycle powered by nuclear reactors. The F-T process was developed nearly 100 years ago as a method of synthesizing liquid fuels from coal. This process presently provides commercial liquid fuels in South Africa, Malaysia, and Qatar, mainly using natural gas as a feedstock. Nuclear energy can be used to separate water into hydrogen and oxygen as well as to extract carbon dioxide from sea water using ion exchange technology. The carbon dioxide and hydrogen react to form synthesis gas, the mixture needed at the beginning of the F-T process. Following further refining, the products, typically diesel and Jet-A, can use existing infrastructure and can power conventional engines with little or no modification. We can then use these carbon-neutral liquid fuels conveniently long into the future with few adverse environmental impacts.

    This paper examines how a market of small-scale stationary fuel cells of up to 20 kW could look like, if costs of stationary fuel cell systems allow market entry. This paper analyses what the market potential for this technology would be, what types of residential buildings might be most attractive, and what would be the quantitative changes in the fuel and the power market. Finally, does the perspective of stationary fuel cells offer a business opportunity for power and gas distribution companies? The methodology of this paper differs from that of other studies in that we model the operation of stationary fuel cells on the basis of 15 min power load profiles of individual buildings. From these we draw synthetic functions describing the fuel cell power output/natural gas input, as a function of a number of specific properties of individual buildings. We then develop a statistical distribution of these properties of the residential building stock in Germany (15 million units), finally using a Monte Carlo simulation the relevant market shares are calculated. The methodology that is developed here has an advantage in that it is flexible and can be applied for different population of buildings. We know, for example, that the results would differ between rural and urban areas. The model may reflect these differences thus allowing deeper insights into future fuel cell housing markets.

  4. Some regional costs of a synthetic fuel industry: The case of illinois

    Attanasi, E.D.; Green, E.K.

    1981-01-01

    The Federal Government's efforts to induce development of a coal-based synthetic fuel industry include direct subsidies, tax concessions, and assurances that it will purchase the industry's output, even if above the market price. In this note it is argued that these subsidies will enable this industry to secure a region's largest and lowest-cost coal deposits and that the costs imposed on other coal users will be substantial. Moreover, because the lowest-cost coal deposits will be committed to synthetic fuels production regardless of the industry's commercial viability, distortions in regional coal markets will develop. If economic efficiency requires that the price of the resource reflect its replacement value, then a State government is justified in imposing a tax on coal destined for subsidized synthetic fuel plants. Amounts of such a tax, based on the higher costs of coal that must be accepted by other users as the result of the subsidized synthetic fuel plants' preempting the largest and lowest-cost deposits, are estimated for the case of Illinois strippable coal. ?? 1981 Annals of Regional Science.

  5. Synthetic and Biomass Alternate Fueling in Aviation

    Hendricks, R. C.; Bushnell, D. M.

    2009-01-01

    While transportation fueling can accommodate a broad range of alternate fuels, aviation fueling needs are specific, such as the fuel not freezing at altitude or become too viscous to flow properly or of low bulk energy density that shortens range. The fuel must also be compatible with legacy aircraft, some of which are more than 50 years old. Worldwide, the aviation industry alone uses some 85-95 billion gallons of hydrocarbon-based fossil fuel each year, which is about 10% of the transportation industry. US civil aviation alone consumes nearly 14 billion gallons. The enormity of the problem becomes overwhelming, and the aviation industry is taking alternate fueling issues very seriously. Biofuels (algae, cyanobacteria, halophytes, weeds that use wastelands, wastewater and seatwater), when properly sourced, have the capacity to be drop-in fuel replacements for petroleum fuels. As such, biojet from such sources solves the aviation CO2 emissions issue without the downsides of 'conventional' biofuels, such as competing with food and fresh water resources. Of the many current fundamental problems, the major biofuel problem is cost. Both research and development and creative engineering are required to reduce these biofuels costs. Research is also ongoing in several 'improvement' areas including refining/processing and biologics with greater disease resistance, greater bio-oil productivity, reduced water/nutrient requirements, etc. The authors' current research is aimed at aiding industry efforts in several areas. They are considering different modeling approaches, growth media and refining approaches, different biologic feedstocks, methods of sequestering carbon in the processes, fuel certification for aviation use and, overall, ensuring that biofuels are feasible from all aspects - operability, capacity, carbon cycle and financial. The authors are also providing common discussion grounds/opportunities for the various parties, disciplines and concerned organization to

Today, with high crude oil market cost and increased demand of energy from China and India, as well as global ecological awareness and need to improve air quality in urban surroundings, many projects are being planned regarding production of synthetic diesel fuel, known as GTL (Gas To Liquid. Most of the future GTL plants are planned in oil exporting countries, such are Qatar and Nigeria, where natural gas as by-product of oil production is being flared, losing in that way precious energy and profit. In that way, otherwise flared natural gas, will be transformed into synthetic diesel fuel which can be directly used in all modern diesel engines. Furthermore, fossil fuel transportation and distribution technology grid can be used without any significant changes. According to lower emissions of harmful gasses during combustion than fossil diesel, this fuel could in the future play a significant part of EU efforts to reach 23% of alternative fuel share till 2020., which are now mostly relied on biodiesel, LPG (liquefied petroleum gas and CNG (compressed natural gas.

    This report examines the federal government's experience in synfuels, the market potential of synfuels, the US energy resources base, and the numerous technologies available. Technologies and energy resources are reviewed and compared to provide the facts needed to understand existing energy-related problems. This introductory manual is an overview of synfuel technologies, and markets. It is not meant to be the sole source of information on which multi-billion dollar investment decisions for specific synfuel plants would be based. The report, published originally in August 1980, has been revised to incorporate appropriate corrections and clarifications. The intent behind these revisions is to present the best technical and programmatic information available as of the original publication date, August 1980. The original report included certain information about the relative costs of selected synfuels technologies. Economics are especially sensitive to recent events and updated information, and it would possibly be misleading to restate the original cost data in this report. It was felt that the original cost data needed major updating and reconciliation due to differences in project scope, basic assumptions, and costing methodologies. ESCOE believes that reliable economic comparisons require timely data and a recognition of any major differences in scope or methodology. Therefore, ESCOE, in a separate task, is undertaking an updated commercial scale economic comparison of selected synfuel processes, on a normalized basis. The results of this task will be published as a separate ESCOE report.

  14. Heavy crude oil and synthetic crude market outlook

    1997-01-01

    This presentation included an outline of the international heavy crude supply and demand versus Canadian heavy crude supply and disposition, and pricing outlook for synthetic crudes. Differences among crude oils such as light sweet, light sour, heavy and bitumen were described and illustrated with respect to their gravity, API, percentage of sulphur, metals and nitrogen. Internationally, heavy and sour crude supplies are forecast to increase significantly over the next four years. Discoveries of light sour crude in offshore Gulf of Mexico will provide a major new source of sour crude to U.S. Gulf Coast refineries. Venezuela's supplies of heavy and sour crude are also expected to increase over the next few years. Mexico and Canada have plans to increase their heavy crude production. All of the crudes will be aimed at the U.S. Gulf Coast and Midwest markets. Pentanes and condensates are also expected to increase based on the growing Canadian natural gas production. Diluent demand will also grow to match Canadian heavy crude/bitumen production. U.S. midwest refiners are proposing expansions to allow them to process more Canadian heavy crude oil. At present, only a few refineries are equipped to process significant amounts of synthetic crude. It was suggested that to absorb available heavy and synthetic production, increased penetration into both Canadian and U.S. markets will be required. Some refineries may have to be modified to process heavy and synthetic oil supplies. Heavy oil and synthetic producers may need to develop relationships with refiners such as joint ventures and term supply agreements to secure markets. 2 tabs., 12 figs

  15. Market dynamics of biomass fuel in California

    1991-01-01

    The California market for biomass fuel purchased by independent power producers has grown substantially since 1980. The PURPA legislation that based power purchase rates upon the 'avoided cost' of public utilities resulted in construction of nearly 900 Megawatts of capacity coming online by 1991. Until 1987, most powerplants were co-sited at sawmills and burned sawmill residue. By 1990 the installed capacity of stand-alone powerplants exceeded the capacity co-sited at wood products industry facilities. The 1991 demand for biomass fuel is estimated as 6,400,000 BDT. The 1991 market value of most biomass fuel delivered to powerplants is from $34 to $47 per BDT. Biomass fuel is now obtained from forest chips, agriculture residue and urban wood waste. The proportion of biomass fuel from the wood products industry is expected to decline and non-traditional fuels are expected to increase in availability

  16. The Role of Synthetic Fuels for a Carbon Neutral Economy

    Full Text Available Fossil fuels depletion and increasing environmental impacts arising from their use call for seeking growing supplies from renewable and nuclear primary energy sources. However, it is necessary to simultaneously attend to both the electrical power needs and the specificities of the transport and industrial sector requirements. A major question posed by the shift away from traditional fossil fuels towards renewable energy sources lies in matching the power demand with the daily and seasonal oscillation and the intermittency of these natural energy fluxes. Huge energy storage requirements become necessary or otherwise the decline of the power factor of both the renewable and conventional generation would mean loss of resources. On the other hand, liquid and gaseous fuels, for which there is vast storage and distribution capacity available, appear essential to supply the transport sector for a very long time ahead, besides their domestic and industrial roles. Within this context, the present assessment suggests that proven technologies and sound tested principles are available to develop an integrated energy system, relying on synthetic fuels. These would incorporate carbon capture and utilization in a closed carbon cycle, progressively relying mostly on solar and/or nuclear primary sources, providing both electric power and gaseous/liquid hydrocarbon fuels, having ample storage capacity, and able to timely satisfy all forms of energy demand. The principles and means are already available to develop a carbon-neutral synthetic fuel economy.

    Biomass energy is an important source of energy in most Asian countries. Households and industries use substantial amounts of fuel wood, charcoal and other biomass energy, such as agricultural residues, dung, leaves and sawmill residues. The main household applications are cooking and heating whereas industrial applications range widely. This paper provides an overview of estimates on the production and trade of biomass fuels in the South-east Asia region. The flows and channels used in the supply of wood fuels in different countries were analysed. This paper may help in identifying policy gaps with regards to the supply and consumption of wood fuels from both forest and non-forest sources. (Author)

    Fuel cell vehicles may create the first mass market for hydrogen as an energy carrier. Directed Technologies, Inc., working with the US Department of Energy hydrogen systems analysis team, has developed a time-dependent computer market penetration model. This model estimates the number of fuel cell vehicles that would be purchased over time as a function of their cost and the cost of hydrogen relative to the costs of competing vehicles and fuels. The model then calculates the return on investment for fuel cell vehicle manufacturers and hydrogen fuel suppliers. The model also projects the benefit/cost ratio for government--the ratio of societal benefits such as reduced oil consumption, reduced urban air pollution and reduced greenhouse gas emissions to the government cost for assisting the development of hydrogen energy and fuel cell vehicle technologies. The purpose of this model is to assist industry and government in choosing the best investment strategies to achieve significant return on investment and to maximize benefit/cost ratios. The model can illustrate trends and highlight the sensitivity of market penetration to various parameters such as fuel cell efficiency, cost, weight, and hydrogen cost. It can also illustrate the potential benefits of successful R and D and early demonstration projects. Results will be shown comparing the market penetration and return on investment estimates for direct hydrogen fuel cell vehicles compared to fuel cell vehicles with onboard fuel processors including methanol steam reformers and gasoline partial oxidation systems. Other alternative fueled vehicles including natural gas hybrids, direct injection diesels and hydrogen-powered internal combustion hybrid vehicles will also be analyzed.

    Previous PNNL work has shown the existing nuclear fuel markets to provide a high degree of supply security, including the ability to respond to supply disruptions that occur for technical and non-technical reasons. It is in the context of new reactor designs – that is, reactors likely to be licensed and market ready over the next several decades – that fuel supply security is most relevant. Whereas the fuel design and fabrication technology for existing reactors are well known, the construction of a new set of reactors could stress the ability of the existing market to provide adequate supply redundancy. This study shows this is unlikely to occur for at least thirty years, as most reactors likely to be built in the next three decades will be evolutions of current designs, with similar fuel designs to existing reactors.

    The nuclear fuel manufacturing constitutes a considerable venture for the competitiveness of the nuclear power sector although it represents a relatively modest fraction (around 4%) of the nuclear kWh cost. The COGEMA group is participating through its branches in the control of the most part (32%) of the world manufacturing capacity of fuel for PWR. Amounting up to 242 operating installations this reactor type is the most widespread in the world. The paper discusses the costs, the fuel clients and the fuel suppliers. Data concerning the boiling water and fast neutron reactors, geographical localization of the PWR and VVER reactors all over the world, the PWR and fuel for PWR manufacturers are also presented

    At present, in the aviation sector considerable scientific project work deals with the development of fuel cell systems based on synthetic fuels to be integrated in future aircraft. The benefits of fuel cell systems in aircraft are various. They offer the possibility to simplify the aircraft layout. Important systems, i.e. the gas turbine powered auxiliary power unit (APU) for electricity supply, the fuel tank inserting system and the water tank, can be substituted by one single system, the fuel cell system. Additionally, the energy demand for ice protection can be covered assisted by fuel cell systems. These measures reduce the consumption of jet fuel, increase aircraft efficiency and allow the operation at low emissions. Additionally, the costs for aircraft related investments, for aircraft maintenance and operation can be reduced. On the background of regular discussions about environmental concerns (global warming) of kerosene Jet A-1 and its availability, which might be restricted in a few years, the aircraft industry is keen to employ synthetic, sulfur-free fuels such as Fischer-Tropsch fuels. These comprise Bio-To-Liquid and Gas-To-Liquid fuels. Within this field of research the Institute of Energy Research (IEF-3) in Juelich develops complete and compact fuel cell systems based on the autothermal reforming of these kinds of fuels in cooperation with industry. This paper reports about this work. (orig.)

    We present a new estimation approach that allows us to extract from spreads in synthetic credit markets the contribution of systematic and idiosyncratic default risk to total default risk. Using an extensive dataset of 90,600 credit default swap and collateralized debt obligation (CDO) tranche...... spreads on the North American Investment Grade CDX index, we conduct an empirical analysis of an intensity-based model for correlated defaults. Our results show that systematic default risk is an explosive process with low volatility, while idiosyncratic default risk is more volatile but less explosive...

    The structure of world markets for uranium, UF6 and enriched uranium product (EUP) have changed greatly since the 1970s. In the old model, firms specializing in mining, conversion, enrichment and fabrication played independent and sequential steps in the making of nuclear fuel. The great majority of users dealt directly with primary suppliers. Competition took place among suppliers at each stage of the fuel cycle and price formation occurred independently for each stage. Long-term contracts directly between primary supplier and end user dominated, whether for U3O8, conversion, enrichment or fabrication. The old model is effectively gone. uranium producers compete with traders, some of whom can offer a much larger menu of products and terms than primary suppliers. Where once there was a straight engineering-like sequence of processing from uranium to EUP for end use, today things are often reversed and far more complicated, with de-enrichment, de-conversion, loans, swaps, and other transactions. Those able to bring financial and entrepreneurial skills to bear on this complexity have an advantage. Long-term contracts between primary producers and end users no longer dominate new transactions, especially in the critical role of price formation - the process of determining or discovery of the market price. These changes have raised the question of whether participants in the nuclear fuel market need, or could benefit from, new institutional mechanisms, specifically some sort of formal exchange or commodity market

    The fuel cell has many potential applications, from power sources for electric hybrid vehicles to small power plants for commercial buildings. The choice of fuel will be critical to the pace of its commercialization. This paper reviews the various liquid fuels being considered as an alternative to direct hydrogen gas for the fuel cell application, presents calculations of the hydrogen and carbon dioxide yields from autothermal reforming of candidate liquid fuels, and reports the product gas composition measured from the autothermal reforming of a synthetic fuel in a micro-reactor. The hydrogen yield for a synthetic paraffin fuel produced by a cobalt-based Fischer-Tropsch process was found to be similar to that of retail gasoline. The advantages of the synthetic fuel are that it contains no contaminants that would poison the fuel cell catalyst, is relatively benign to the environment, and could be transported in the existing fuel distribution system.

  10. WNA 2013 Fuel Market Report

    2014-01-01

    Conclusions: • WNA nuclear capacity projections have been revised downwards since the 2011 report. Nuclear capacity is still projected to increase at a faster rate than anytime since the 1980s to 574GW by 2030 in the reference scenario leading to projected uranium requirements of 97,000tU. • Increased uranium market uncertainty has resulted in the cancellation and deferment of a number of mining projects. Our uranium production methodology has also become more objective. As a result, existing and expected capacity plus secondary supply will be insufficient on current plans to meet reference scenario requirements by about 2024. • Conversion capacity will need to increase utilisation rates after 2017 in the reference scenario in order to meet requirements. • Enrichment capacity will adjust to current surpluses; underfeeding is expected to increase. • Fabrication capacity is expected to be sufficient to meet expected reactor requirements. • Beyond 2030 Generation IV reactors could change future uranium requirements but not to a significant degree before 2050.

    Acurex Environmental Corporation is bringing Clean Fuel to the environmentally demand Krakow market, through the cooperative agreement with the U.S. Department of Energy. Clean fuel is a proprietary clean burning coal-based energy source intended for use in stoves and hand stoked boilers. Clean Fuel is a home heating fuel that is similar in form and function to raw coal, but is more environmentally friendly and lower in cost. The heating value of Clean Fuel is 24,45 kJ/kg. Extensive sets of confirmation runs were conducted in the Academy of Mining and Metallurgy in the Krakow laboratories. It demonstrated up to 54 percent reduction of particulate matter emission, up to 35 percent reduction of total hydrocarbon emissions. Most importantly, polycyclic aromatic hydrocarbons (toxic and carcinogens compounds) emissions were reduced by up to 85 percent, depending on species measured. The above comparison was made against premium chunk coal that is currently available in Krakow for approximately $83 to 93/ton. Clean Fuel will be made available in Krakow at a price approximately 10 percent lower than that of the premium chunk coal.

    1977-01-01

    The application of very high temperature blankets to improved efficiency of electric power generation and production of H 2 and H 2 based synthetic fuels is described. The blanket modules have a low temperature (300 to 400 0 C) structure (SS, V, Al, etc.) which serves as the vacuum/coolant pressure boundary, and a hot (>1000 0 C) thermally insulated interior. Approximately 50 to 70% of the fusion energy is deposited in the hot interior because of deep penetration by high energy neutrons. Separate coolant circuits are used for the two temperature zones: water for the low temperature structure, and steam or He for the hot interior. Electric generation efficiencies of approximately 60% and H 2 production efficiencies of approximately 50 to 70%, depending on design, are projected for fusion reactors using these high temperature blankets

    In today's context of environment protection cares and in agreement with the actions carried out by the local authorities and organizations, the LPG-fuel appears in the media with a reviving good and credible reputation. However, one can ask about its real perspectives of development. This short paper analyses the conditions for this development at the international and at the national scale. LPG-fuel is the most used and most performing alternative fuel in the world and can contribute to the energy independence of the countries with national LPG resources. Its technological mastery leads progressively the car manufacturers to propose vehicles already equipped with dual-fuel engines, but to reach its expected success, LPG-fuel needs a financial aid from the national authorities in the form of taxes reduction. Its privileged markets are the taxicabs, the public transportation systems and the fleets of intervention vehicles. In France, the network of LPG distribution stations is progressively reinforcing but a revision of the legal texts concerning the training of personnel and the approval of repair shops must be updated.

    2002-01-01

    Implementation of the Kyoto Protocol is likely to leave Russia and other Eastern European countries with market power in the market for emission permits. Ceteris paribus, this will raise the permit price above the competitive permit price. However, Russia is also a large exporter of fossil fuels. A high price on emission permits may lower the producer price on fossil fuels. Thus, if Russia co-ordinates its permit market and fossil fuel market policies, market power will not necessarily lead to a higher permit price. Fossil fuel producers may also exert market power in the permit market, provided they conceive the permit price to be influenced by their production volumes. If higher volumes drive up the permit price Russian fuel producers may become more aggressive relative to their competitors in the fuel markets. If the sale of fuels is co-ordinated with the sale of permits. The result is reversed if high fuel production drives the permit price down. (Author)

    The geographical variation in Swedish wood fuel market characteristics for the district heating sector has been studied using Geographical Information Systems (GIS) and cross-sectional Tobit analysis. The results indicate that local availability and competition for wood fuels influence the wood fuel consumption at inland heating plants. The factors affecting the decision to use wood fuel at heating plants close to seaports, however, were not captured by the model, suggesting that coastal location reduces dependency on the local wood fuel market. The effects of changes in local wood fuel availability on wood fuel use by an inland heating plant are presented and discussed

    Bioethanol produced by fermenting lignocellulosic biomass and synthetic biofuels are known as second generation biofuels. These biofuels are produced using the whole plant including cellulose, hemicellulose and lignin. Ethanol is the product of fermentative biomass conversion. Synthetic biofuels, the so-called BtL (biomass to liquid) processes, are produced using thermochemical biomass conversion. Here, in the first process step, the hydrocarbon structure of the biomass is converted to syngas, a mixture of carbon monoxide (CO) and hydrogen (H2). The second process step uses the purified and conditioned syngas for chemical fuel synthesis. The outcome of the synthesis is gasoline, diesel, or tailor-made fuels for advanced fuel-efficient and low-emission engines. R and D on synthetic biofuel processes is being conducted in several countries around the world, but the global technology leader is without doubt the German company, CHOREN Industries Ltd. in Freiberg, Saxony. Since 1998, CHOREN has been operating a pilot plant for the production of biofuels. At present this plant is being up-scaled and the first commercial production worldwide will start in 2007 with a capacity of 15,000 t/a biofuel. Annually 65,000 t of wood will be processed, including scrap wood. This will produce a high-quality diesel product, marketed under the brand name ''SunDiesel''. This product requires neither any modification to the diesel engine nor to the refueling technique. Because the whole plant is processed, 4,000 l diesel equivalent can be obtained from one hectare of crop. This yield is almost three times that of biodiesel produced from rape. Compared with diesel produced from crude oil, synthetic biofuels reduce the CO{sub 2} emissions by more than 80 %. Nevertheless, the establishment of a synthetic biofuels industry cannot be justified based on climate protection arguments, because the CO{sub 2} balance of direct biomass combustion is more favourable.

  6. Market study on the potential for peat as a fuel

    International Nuclear Information System (INIS)

    1991-01-01

    A report is given on the market potential for peat as a fuel in Scotland. It is concluded that there are two distinct market segments, domestic and industrial/commercial. There is no potential for peat as a fuel in the industrial/commercial segment but there is opportunity for increased peat usage in the domestic sector. The greatest potential for market development is conversion of existing solid fuel users to peat. Pro-active input is required to realise this market potential. The market is constrained by demand.

    The existing uranium reserves cover the needs for at least 80 years, the probable ones are 2 to 5 times larger, seawater is an unlimited source of uranium. On the spot market the price was in 1985 355 SEK/kg U, the long-period contracts are expected to be at 700 SEK/kg U. Uranium is supplied to Finland and Sweden from Australia, Canada, France, Niger and Gabon. Conversion (about 50 SEK/kg U) is supplied to Finland and Sweden by Eldorado Resources Canada, Comurhex France, BNFL Great Britain and Allied Chemical USA. Prices for enrichment are at least 1200 SEK/kg SWU for USA and 900 SEK/kg SWU for European enrichment. Enrichment is supplied to Finland and Sweden by Eurodif France, Urenco Holland, West Germany and Great Britain, USA DOE and Techsnabexport USSR. There is about 90% exceeding capacity of fabrication. Fabrication is supplied by ASEA-ATOM Sweden, Exxon USA and FRG FRAGEMA France, KWU/FRG and Atomenergoexport USSR. These five suppliers offer 7 essentially different designs. Prices range from 1200 to 1800 SEK/kg U. Sweden established storage facility for used fuel CLAB in 1985, Finland will have such facility ready in 1987. Both Sweden and Finland are investigating disposal. Sweden has a contract for processing of a minor burnt-out fuel batch in England and France. Sweden attempts to reduce the quantities to be processed. A levellized fuel price for a nuclear power plant set into operation in 1990-ties is estimated as 6.6 SE oere/kWh. (eg)

    Fuel Cells are often considered in the market place as just power providers. Whilst fuel cells do provide power, there are additional beneficial characteristics that should be highlighted to consumers. Due to the high price premiums associated with fuel cells, added value features need to be exploited in order to make them more appealing and increase unit sales and market penetration. This paper looks at the approach taken by two companies to sell high value fuel cells to niche markets. The first, SFC Energy, has a proven track record selling fuel cell power providers. The second, Bloom Energy, is making significant progress in the US by having sold its Energy Server to more than 40 corporations including Wal-Mart, Staples, Google, eBay and Apple. Further to these current markets, two prospective added value applications for fuel cells are discussed. These are fuel cells for aircraft APUs and fuel cells for fire prevention. These two existing markets and two future markets highlight that fuel cells are not just power providers. Rather, they can be used as solutions to many needs, thus being more cost effective by replacing a number of incumbent systems at the same time.

    Liquid fuels can be produced from coal in a number of indirect and direct liquefaction processes. While indirect coal liquefaction has been proved commercially outside the United States, most attention in this country has focused on the direct liquefaction processes, which include the processes under examination in this report; namely, the Exxon Donor Solvent (EDS), the H-Coal, and the Solvent Refined Coal (SRC) II processes. The objectives of the study were to: compare the boiler fuels of direct coal liquefaction with residual fuel oil (No. 6 fuel oil) including physical characteristics and environmental hazards, such as carcinogenic characteristics and toxic hazard characteristics; determine whether a boiler fuel market would exist for the coal liquefaction products given their physical characteristics and potential environmental hazards; determine the advantages of utilizing methanol as a boiler fuel on a continuous basis in commercial boilers utilizing existing technology; identify the potential regional candidate markets for direct coal liquefaction products as liquid boiler fuels; determine the distributing and handling costs associated with marketing coal liquefaction products as liquid boiler fuels; determine the current regulatory issues associated with the marketing of coal liquefaction products as boiler fuels; and determine and evaluate other institutional issues associated with the marketing of direct coal liquefaction products as boiler fuels.

  15. Powered by technology or powering technology?---Belief-based decision-making in nuclear power and synthetic fuel

    Science.gov (United States)

    Yang, Chi-Jen

    The overarching question in this study is how and why technical-fixes in energy policy failed. In the post-WWII era, civilian nuclear power and synthetic fuel had both been top priorities on the U.S. national policy agenda during certain periods of time. Nuclear power was promoted and pursued persistently with great urgency for over two decades. In contrast, synthetic fuel policy suffered from boom-and-bust cycles. The juxtaposition of policy histories of nuclear power and synthetic fuel highlights many peculiarities in policymaking. The U.S. government forcefully and consistently endorsed the development of civilian nuclear power for two decades. It adopted policies to establish the competitiveness of civilian nuclear power far beyond what would have occurred under free-market conditions. Even though synthetic fuel was characterized by a similar level of economic potential and technical feasibility, the policy approach toward synthetic fuel was almost the opposite of nuclear power. Political support usually stopped when the development of synthetic fuel technology encountered economic difficulties. The contrast between the unfaltering faith in nuclear power and the indeterminate attitude toward synthetic fuel raises many important questions. I argue that these diverging paths of development can be explained by exploring the dominant government ideology of the time or "ideology of the state" as the sociology literature describes it. The price-determining approach was a result of government preoccupied with fighting the Cold War. The U.S. intentionally idealized and deified nuclear power to serve its Cold War psychological strategy. These psychological maneuverings attached important symbolic meaning to nuclear power. The society-wide enthusiasm and resulting bandwagon market are better understood by taking the role of symbolism in the political arena into account. On the other hand, a "welfare state" ideology that stood behind synthetic fuel was confused

    Dynamic price information flows among U.S. electricity wholesale spot prices and the prices of the major electricity generation fuel sources, natural gas, uranium, coal, and crude oil, are studied. Multivariate time series methods applied to weekly price data show that in contemporaneous time peak electricity prices move natural gas prices, which in turn influence crude oil. In the long run, price is discovered in the fuel sources market (except uranium), as these prices are weakly exogenous in a reduced rank regression representation of these energy prices.

    The paper discusses the influence of regional fuel stocks on the reliability of the energy sector's activities in a given region. The authors give classification of stocks by their purpose and describe their role in avoiding energy shortage situations. The fuel deficiency at a regional fuel market is shown in connection with the resulting loss for the national economy. The authors employ imitative modelling for investigation of fuel supply schemes acting in Latvia. They estimate possible expenses on the maintenance of fuels - such as gas, residual oil, and coal - for different variants of fuel delivery. (author)

  20. Regional prices in the Swedish wood-fuel market

    1999-01-01

    This paper analyses, through a statistical survey, the regional distribution of prices on the commercial wood-fuel market for district heating plants and the pellets market for single family houses. The existing market watch of the national Swedish wood-fuel market has been developed for both refined and unrefined wood-fuels. The last five years the trend for wood-fuel prices on the district heating market has been stable, with a slight increase in the price of refined wood-fuels. However, on the young and fast-growing household market for pellets, prices have increased 12% during the last three years. The distribution of prices for northern, middle and southern Sweden indicates differences within 5% between the regions. The limited price difference between Swedish regions are a product of a large domestic supply and an increasing trade among regions in Europe, putting pressure on prices. Regional differences, mirrored as transportation distances and local production costs are key factors that could explain this regional price variation. However, the development of a commercial market with less regulation tends to level out prices. Consumers on the household market purchase small quantities and do not have the same possibility as district heating companies to take advantage of the oversupply opportunity and thus face a faster price development. The weaker market position of the consumers also tends to give homogeneous prices between regions of the residential sector. (Author)

    This paper is a synthesis of an internal note of the French Butane and Propane Committee (CFBP) about the perspectives of the worldwide market of LPG fuels. The conclusion of this study is that the market will not be short of LPG, in particular the French market and the automotive fuels. The consumption of LPG fuels for vehicles in France is growing up rapidly (about 100% in 1997 with respect to 1996: 90000 t consumed in 1997 by 70000 vehicles) and the resource remains important and can reach 3 millions of tons per year.

    Planning for residual fuel oil usage and management remains an important part of the generation fuel planning and management function for many utilities. EPRI's Utility Planning Methods Center has maintained its analytical overview of the fuel oil markets as part of its overall fuel planning and management research program. This overview provides an update of recent fuel oil market directions. Several key events of the past year have had important implications for residual fuel oil markets. The key events have been the changes brought about by the Persian Gulf War and its aftermath, as well as continuing environmental policy developments. The Persian Gulf conflict has created renewed interest in reducing fuel oil use by utilities as part of an overall reduction in oil imports. The policy analysis performed to date has generally failed to properly evaluate utility industry capability. The Persian Gulf conflict has also resulted in an important change in the structure of international oil markets. The result of this policy-based change is likely to be a shift in oil pricing strategy. Finally, continued change in environmental requirements is continuing to shift utility residual oil requirements, but is also changing the nature of the US resid market itself

    In 2014, the annual report of the Her Majesty's Chief Inspector of Prisons (HMIP) for England and Wales raised concerns regarding New Psychoactive Substance (NPS) use in custody, specifically the consumption of synthetic cannabinoids. To date, however, the use of these substances in prison populations, and the markets that have emerged to facilitate it, have been under-researched. Our research was conducted in an English adult male prison using multi-method techniques. These included: in-depth interviews and focus groups with prison staff and prisoners; observations of prisoner-led focus groups, workshops and restorative justice circles involving discussion of synthetic cannabinoid use and markets; and analysis of routinely collected prison data measuring drug seizures, incidents of violence and incidents of self-harm. The findings highlight: (1) the scale and nature of synthetic cannabinoid markets in a custodial setting and the motivations for establishing them; (2) the nature and motivations for synthetic cannabinoids use in prison; and (3) the impact synthetic cannabinoid markets in this setting have upon prisoners, the prison system and the wider criminal justice system. The policy implications of the stated motivations for use and reported problems are discussed in relation to both prison and community settings, and the recently implemented Psychoactive Substance Act (2016). The paper concludes that the rise in synthetic cannabinoid use in custody and the size of the drug market are posing significant challenges to the management of offenders; including healthcare, appropriate detection techniques, license recall and sanctions for both use and supply. We argue that the primary motivation for consumption in this setting is the avoidance of drug use detection, and that this is likely to supersede other motivations for consumption in the future. We propose a revision of the use of mandatory drug tests (MDTs) both in prisons and in the management of offenders in

    In Ref. 1, a new model for the description of the financial markets dynamics has been proposed. Traders move on a two dimensional lattice and interact by means of mechanisms of mutual influence. In the present paper, we present results from large-scale simulations of the same model enhanced by the introduction of rational traders modeled as moving-averages followers. The dynamics now accounts for log-normal distribution of volatility which is consistent with some observation of real financial indexes7 at least for the central part of the distribution.

The thesis try to explain the impact of the London IPE future market on spot prices too. The mainstream research has demonstrated that co-integration seems to be the best theoretical approach to investigate the long run equilibrium relations. A particular attention will be devoted to the structural change in the econometric modelling on these equilibriums. A deep analysis of the main European petroleum products markets permit a better model specification concerning each of these markets. Further, we will test if any evidence of relations between spot and domestic prices could be confirmed. Finally, alternative scenarios will be depicted to forecast prices in the petroleum products markets. The objective is to observe the model reaction to changes crude oil prices. (author)

    Segments of fuel and clad have been leached in deionized water and in groundwater. The leachants were centrifuged through membrane filters. Both centrifugate and the filters were analysed for U, Sr-90, α- and γ-emitters. The results are discussed in terms of preferential leaching, solubility limitations and adsorption effects. For U an apparent saturation at about 800 ppb was observed. Pu also appeared to attain saturation at a few ppb. For Sr the leach rate was 3x10 -7 /d after ca 400 days. Attempts to impose reducing conditions showed decreased leach rates. (Authors)

    Leaching of high burnup BWR fuel for up to 3 years showed that both U and Pu attain saturation rapidly at pH 8.1, giving values of 1-2 mg/l and 1 μg/l respectively. The leaching rate for Sr-90 decreased from about 10 -5 /d to 10 -7 /d but was always higher than the rates for U, Pu, Cm, Ce, Eu and Ru. Congruent dissolution was only attained at pH values of about 4. When reducing conditions were imposed on the pH 8.1 groundwater by means of H 2 /Ar in the presence of a Pd catalyst, significanly lower leach rates were attained. The hypothesis that alpha radiolytic decomposition of water is a driving force for UO 2 corrosion even under reducing conditions has been examined in leaching tests on low burnup (low alpha dose-rate) fuel. No significant effect of alpha radiolysis under the experimental conditions was detected. Thermodynamically the calculated uranium solubilities in the pH range 4-8.2 generally agreed, well with the measured ones, although assumptions made for certain parameters in the calculations limit the validity of the results.

    2016-01-01

    This paper analyzes a number of carbon neutral cycles, which could be used to produce synthetic hydrocarbon fuels. Synthetic hydrocarbons are produced via the synthesis of Carbon Monoxide and Hydrogen. The . cycles considered will either utilize Gasification processes, or carbon capture as a source of feed material. In addition the cycles will be coupled to a small modular Nuclear Reactor (SMR) as a power and heat source. The goal of this analysis is to reduce or eliminate the need to transport diesel and other fossil fuels to remote regions and to provide a carbon neutral, locally produced hydrocarbon fuel for remote communities. The technical advantages as well as the economic case are discussed for each of the cycles presented. (author)

  20. Metabolic Engineering for Production of Biorenewable Fuels and Chemicals: Contributions of Synthetic Biology

    Directory of Open Access Journals (Sweden)

    Laura R. Jarboe

    2010-01-01

    Full Text Available Production of fuels and chemicals through microbial fermentation of plant material is a desirable alternative to petrochemical-based production. Fermentative production of biorenewable fuels and chemicals requires the engineering of biocatalysts that can quickly and efficiently convert sugars to target products at a cost that is competitive with existing petrochemical-based processes. It is also important that biocatalysts be robust to extreme fermentation conditions, biomass-derived inhibitors, and their target products. Traditional metabolic engineering has made great advances in this area, but synthetic biology has contributed and will continue to contribute to this field, particularly with next-generation biofuels. This work reviews the use of metabolic engineering and synthetic biology in biocatalyst engineering for biorenewable fuels and chemicals production, such as ethanol, butanol, acetate, lactate, succinate, alanine, and xylitol. We also examine the existing challenges in this area and discuss strategies for improving biocatalyst tolerance to chemical inhibitors.

  1. MHD power generation for the synthetic-fuels industry

    International Nuclear Information System (INIS)

    Jones, M.S. Jr.

    1982-01-01

    The integration of open cycle MHD with various processes for the recovery of hydrocarbons for heavy oil deposits, oil sands, and oil shales are examined along with its use in producing medium Btu gas, synthetic natural gas and solvent refined coal. The major features of the MHD cycle which are of interest are: (a) the ability to produce hydrogen through the shift reaction by introducing H 2 O into the substoichiometric combustion product flow exiting the MHD diffuser, (b) the use of high temperature waste heat in the MHD exhaust, and (c) the ability of the seed in the MHD flow to remove sulfur from the combustion products. Therefore the use of the MHD cycle allows coal to be used in an environmentally acceptable manner in place of hydrocarbons which are now used to produce process heat and hydrogen. The appropriate plant sizes are in the range of 25 to 50 MWe and the required MHD generator enthalpy extraction efficiencies are low. Sale of electricity produced, over and above that used in the process, can provide a revenue stream which can improve the economics of the hydrocarbon processing. This, coupled with the replacement of coal for hydrocarbons in certain phases of the process, should improve the overall economics, while not requiring a high level of performance by the MHD components. Therefore, this area should be an early target of opportunity for the commercialization of MHD

  2. Towards a methanol economy: Zeolite catalyzed production of synthetic fuels

    DEFF Research Database (Denmark)

    Mentzel, Uffe Vie

    The main focus of this thesis is zeolite catalyzed conversion of oxygenates to hydrocarbon fuels and chemicals. Furthermore, conversion of ethane to higher hydrocarbons has also been studied. After a brief introduction to the concept of “the methanol economy” in the first chapter, the second...... a commercial H-ZSM-5 zeolite impregnated with gallium and/or molybdenum is described. The object was to investigate if the presence of methanol in the feed could enhance the conversion of ethane, but in all cases the opposite is observed; the presence of methanol actually suppresses the conversion of ethane...... various zeolite catalysts is studied in Chapter 4. When 2-propanol or 1-butanol is converted over H-ZSM-5, the total conversion capacities of the catalyst are more than 25 times higher than for conversion of methanol and ethanol. Furthermore, for conversion of C3+ alcohols, the selectivity shifts during...

    2012-07-01

    This domestic project, Future Combustion Technology for Synthetic and Renewable Fuels in Compression Ignition Engines (ReFuel), was part of a Collaborative Task 'Future Combustion Technology for Synthetic and Renewable Fuels in Transport' of International Energy Agency (IEA) Combustion Agreement. This international Collaborative Task is coordinated by Finland. The three-year (2009-2011) prooject was a joint research project with Aalto University (Aalto), Tampere University of Technology (TUT), Technical Research Centre of Finland (VTT) and Aabo Akademi University (AAU). The project was funded by TEKES, Waertsilae Oyj, Agro Sisu Power, Aker Arctic Technology Oy and the research partners listed above. Modern renewable diesel fuels have excellent physical and chemical properties, in comparison to traditional crude oil based fuels. Purely paraffinic fuels do not contain aromatic compounds and they are totally sulphur free. Hydrotreated Vegetable Oil (HVO) was studied as an example of paraffinic high cetane number (CN) diesel fuels. HVO has no storage and low temperature problems like the fatty acid methyl esters (FAMEs) have. The combustion properties are better than those of crude oil based fuels and FAME, because they have very high cetane numbers and contain no polyaromatic hydrocarbons (PAH). With low HVO density, viscosity and distillation temperatures, these advantageous properties allow far more advanced combustion strategies, such as very high exhaust gas recirculation (EGR) rates or extreme Miller timings, than has been possible with current fossil fuels. The implementation of these advanced combustion technologies, together with the novel renewable diesel fuel, brought significant nitrogen oxides (NO{sub x}), particulate matter (PM) emission reductions with no efficiency losses.

    The US market for nuclear fuel fabrication services is characterized by an annual production capacity significantly in excess of both current and anticipated demand. The trends toward longer operating cycle lengths and higher burnup fuel continue in the United States. This, together with the lack of any prospects for new light water reactors coming on line in the US during the next ten years, is expected to hold the annual demand for fuel fabrication services from US LWRs at around 2000t of uranium into the next century.

  10. Overview of Aviation Fuel Markets for Biofuels Stakeholders

    Energy Technology Data Exchange (ETDEWEB)

    Davidson, C.; Newes, E.; Schwab, A.; Vimmerstedt, L.

    2014-07-01

    This report is for biofuels stakeholders interested the U.S. aviation fuel market. Jet fuel production represents about 10% of U.S. petroleum refinery production. Exxon Mobil, Chevron, and BP top producers, and Texas, Louisiana, and California are top producing states. Distribution of fuel primarily involves transport from the Gulf Coast to other regions. Fuel is transported via pipeline (60%), barges on inland waterways (30%), tanker truck (5%), and rail (5%). Airport fuel supply chain organization and fuel sourcing may involve oil companies, airlines, airline consortia, airport owners and operators, and airport service companies. Most fuel is used for domestic, commercial, civilian flights. Energy efficiency has substantially improved due to aircraft fleet upgrades and advanced flight logistic improvements. Jet fuel prices generally track prices of crude oil and other refined petroleum products, whose prices are more volatile than crude oil price. The single largest expense for airlines is jet fuel, so its prices and persistent price volatility impact industry finances. Airlines use various strategies to manage aviation fuel price uncertainty. The aviation industry has established goals to mitigate its greenhouse gas emissions, and initial estimates of biojet life cycle greenhouse gas emissions exist. Biojet fuels from Fischer-Tropsch and hydroprocessed esters and fatty acids processes have ASTM standards. The commercial aviation industry and the U.S. Department of Defense have used aviation biofuels. Additional research is needed to assess the environmental, economic, and financial potential of biojet to reduce greenhouse gas emissions and mitigate long-term upward price trends, fuel price volatility, or both.

  11. An analysis of heating fuel market behavior, 1989--1990

    Energy Technology Data Exchange (ETDEWEB)

    1990-06-01

    The purpose of this report is to fully assess the heating fuel crisis from a broader and longer-term perspective. Using EIA final, monthly data, in conjunction with credible information from non-government sources, the pricing phenomena exhibited by heating fuels in late December 1989 and early January 1990 are described and evaluated in more detail and more accurately than in the interim report. Additionally, data through February 1990 (and, in some cases, preliminary figures for March) make it possible to assess the market impact of movements in prices and supplies over the heating season as a whole. Finally, the longer time frame and the availability of quarterly reports filed with the Securities and Exchange Commission make it possible to weigh the impact of revenue gains in December and January on overall profits over the two winter quarters. Some of the major, related issues raised during the House and Senate hearings in January concerned the structure of heating fuel markets and the degree to which changes in this structure over the last decade may have influenced the behavior and financial performance of market participants. Have these markets become more concentrated Was collusion or market manipulation behind December's rising prices Did these, or other, factors permit suppliers to realize excessive profits What additional costs were incurred by consumers as a result of such forces These questions, and others, are addressed in the course of this report.

    2010-01-01

    Wind and solar power is troubled by large fluctuations in delivery due to changing weather. The surplus electricity can be used in a Solid Oxide Electrolyzer Cell (SOEC) to split CO2 + H2O into CO + H2 (+O2). The synthesis gas (CO + H2) can subsequently be catalyzed into various types of synthetic...... fuels using a suitable catalyst. As the catalyst operates at elevated pressure the fuel production system can be simplified by operating the SOEC at elevated pressure. Here we present the results of a cell test with pressures ranging from 0.4 bar to 10 bar. The cell was tested both as an SOEC...

  13. Synthetic fuels and the environment: an environmental and regulatory impacts analysis

    1980-06-01

    Since July 1979 when DOE/EV-0044 report Environmental Analysis of Synthetic Liquid fuels was published the synthetic fuels program proposals of the Administration have undergone significant modifications. The program year for which the development goal of 1.5 million barrels per day is to be reached has been changed from 1990 to 1995. The program plan is now proposed to have two stages to ensure, among other things, better environmental protection: an initial stage emphasizing applied research and development (R and D), including environmental research, followed by a second stage that would accelerate deployment of those synthetic fuel technologies then judged most ready for rapid deployment and economic operation within the environmental protection requirements. These program changes have significantly expanded the scope of technologies to be considered in this environmental analysis and have increased the likelihood that accelerated environmental R and D efforts will be successful in solving principal environmental and worker safety concerns for most technologies prior to the initiation of the second stage of the accelerated deployment plan. Information is presented under the following section headings: summary; study description; the technologies and their environmental concerns (including, coal liquefaction and gasification, oil shale production, biomass and urban waste conversion); regulatory and institutional analyses; and environmental impacts analysis (including air and water quaility analyses, impacts of carbon dioxide and acid rain, water availability, solid and hazardous wastes, coal mining environmental impacts, transportation issues, community growth and change, and regional impacts). Additional information is presented in seventeen appendixes. (JGB)

    Full Text Available Traditionally materials have been associated with a series of physical properties that can be used as inputs to production and manufacturing. Recently we witnessed an interest in materials considered not only as ‘true matter’, but also as new breeds where geometry, texture, tooling and finish are able to provoke new sensations when they are applied to a substance. These artificial materials can be described as synthetic because they are the outcome of various qualities that are not necessarily true to the original matter, but they are the combination of two or more parts, whether by design or by natural processes. The aim of this paper is to investigate the potential of architectural surfaces to produce effects through the invention of new breeds of artificial matter, using micro-scale details derived from Nature as an inspiration.

  15. Workshop Papers: Directions and Marketing of Synthetic Crude Oil and Heavy Oil

    International Nuclear Information System (INIS)

    1997-01-01

    This workshop was organized by the National Centre for Upgrading Technology in an effort to bring together experts from the various sectors of the petroleum industry to outline their views of the directions that the synthetic crude oil market will pursue over the next decade and into the 21. century. The motivation for the Workshop came from the many announcements during 1996 and 1997 by several Canadian oil companies about plans to initiate or expand their heavy oil and synthetic crude production. During the same period, at least one US refiner also announced plans to revamp an existing refinery to allow it to process Canadian heavy oil and synthetic crude. The workshop was organized to review these plans and to discuss such questions as (1) Would the selected technologies be the familiar carbon rejection or hydrogen addition methods, or would there be radical advanced technologies? (2) Would the products be fully or partially upgraded? (3) How would they be processed in the refinery? (4) Would there be a market? This collection of papers or viewgraphs comprise all the formal presentations given at the workshop. The final section also contains the edited notes recorded during the question and answer periods. refs., tabs., figs

  18. A methodology for assessing the market benefits of alternative motor fuels: The Alternative Fuels Trade Model

    Energy Technology Data Exchange (ETDEWEB)

    Leiby, P.N.

    1993-09-01

    This report describes a modeling methodology for examining the prospective economic benefits of displacing motor gasoline use by alternative fuels. The approach is based on the Alternative Fuels Trade Model (AFTM). AFTM development was undertaken by the US Department of Energy (DOE) as part of a longer term study of alternative fuels issues. The AFTM is intended to assist with evaluating how alternative fuels may be promoted effectively, and what the consequences of substantial alternative fuels use might be. Such an evaluation of policies and consequences of an alternative fuels program is being undertaken by DOE as required by Section 502(b) of the Energy Policy Act of 1992. Interest in alternative fuels is based on the prospective economic, environmental and energy security benefits from the substitution of these fuels for conventional transportation fuels. The transportation sector is heavily dependent on oil. Increased oil use implies increased petroleum imports, with much of the increase coming from OPEC countries. Conversely, displacement of gasoline has the potential to reduce US petroleum imports, thereby reducing reliance on OPEC oil and possibly weakening OPEC`s ability to extract monopoly profits. The magnitude of US petroleum import reduction, the attendant fuel price changes, and the resulting US benefits, depend upon the nature of oil-gas substitution and the supply and demand behavior of other world regions. The methodology applies an integrated model of fuel market interactions to characterize these effects.

    The ability to generate microorganisms that can produce biofuels similar to petroleum-based transportation fuels would allow the use of existing engines and infrastructure and would save an enormous amount of capital required for replacing the current infrastructure to accommodate biofuels that have properties significantly different from petroleum-based fuels. Several groups have demonstrated the feasibility of manipulating microbes to produce molecules similar to petroleum-derived products, albeit at relatively low productivity (e.g. maximum butanol production is around 20 g/L). For cost-effective production of biofuels, the fuel-producing hosts and pathways must be engineered and optimized. Advances in metabolic engineering and synthetic biology will provide new tools for metabolic engineers to better understand how to rewire the cell in order to create the desired phenotypes for the production of economically viable biofuels.

    Price volatility spillovers among China’s crude oil, corn and fuel ethanol markets are analyzed based on weekly price data from September 5, 2003 to August 31, 2012, employing the univariate EGARCH model and the BEKK-MVGARCH model, respectively. The empirical results indicate a higher interaction among crude oil, corn and fuel ethanol markets after September, 2008. In the overall sample period, the results simultaneously provide strong evidence that there exist unidirectional spillover effects from the crude oil market to the corn and fuel ethanol markets, and double-directional spillovers between the corn market and the fuel ethanol market. However, the spillover effects from the corn and fuel ethanol markets to the crude oil market are not significant. -- Highlights: •Employing univariate EGARCH model and BEKK-MVGARCH model, respectively. Unidirectional spillover effects from crude oil market to corn and fuel ethanol markets. •Double-directional spillovers between corn market and fuel ethanol market. •The spillover effects from corn and fuel ethanol markets to crude oil market are not significant. •The empirical results indicate a higher interaction among crude oil, corn and fuel ethanol markets after September, 2008

  1. Enhanced fuel efficiency on tractor-trailers using synthetic jet-based active flow control

    Science.gov (United States)

    Amitay, Michael; Menicovich, David; Gallardo, Daniele

    2016-04-01

    The application of piezo-electrically-driven synthetic-jet-based active flow control to reduce drag on tractor-trailers was explored experimentally in wind tunnel testing as well as full-scale road tests. Aerodynamic drag accounts for more than 50% of the usable energy at highway speeds, a problem that applies primarily to trailer trucks. Therefore, a reduction in aerodynamic drag results in large saving of fuel and reduction in CO2 emissions. The active flow control technique that is being used relies on a modular system comprised of distributed, small, highly efficient actuators. These actuators, called synthetic jets, are jets that are synthesized at the edge of an orifice by a periodic motion of a piezoelectric diaphragm(s) mounted on one (or more) walls of a sealed cavity. The synthetic jet is zero net mass flux (ZNMF), but it allows momentum transfer to flow. It is typically driven near diaphragm and/or cavity resonance, and therefore, small electric input [O(10W)] is required. Another advantage of this actuator is that no plumbing is required. The system doesn't require changes to the body of the truck, can be easily reconfigured to various types of vehicles, and consumes small amounts of electrical power from the existing electrical system of the truck. Preliminary wind tunnel results showed up to 18% reduction in fuel consumption, whereas road tests also showed very promising results.

  2. Geography of Existing and Potential Alternative Fuel Markets in the United States

    Energy Technology Data Exchange (ETDEWEB)

    Johnson, C.; Hettinger, D.

    2014-11-01

    When deploying alternative fuels, it is paramount to match the right fuel with the right location, in accordance with local market conditions. We used six market indicators to evaluate the existing and potential regional market health for each of the five most commonly deployed alternative fuels: electricity (used by plug-in electric vehicles), biodiesel (blends of B20 and higher), E85 ethanol, compressed natural gas (CNG), and propane. Each market indicator was mapped, combined, and evaluated by industry experts. This process revealed the weight the market indicators should be given, with the proximity of fueling stations being the most important indicator, followed by alternative fuel vehicle density, gasoline prices, state incentives, nearby resources, and finally, environmental benefit. Though markets vary among states, no state received 'weak' potential for all five fuels, indicating that all states have an opportunity to use at least one alternative fuel. California, Illinois, Indiana, Pennsylvania, and Washington appear to have the best potential markets for alternative fuels in general, with each sporting strong markets for four of the fuels. Wyoming showed the least potential, with weak markets for all alternative fuels except for CNG, for which it has a patchy market. Of all the fuels, CNG is promising in the greatest number of states--largely because freight traffic provides potential demand for many far-reaching corridor markets and because the sources of CNG are so widespread geographically.

  3. The market and consumer welfare effects of mid-level ethanol blends in the US fuel market

    International Nuclear Information System (INIS)

    Gallagher, Paul W.; Sleper, Daniel

    2016-01-01

    This study examines the prospect that a consumer-driven market could eventually replace the myriad regulations and demand quotas in the US ethanol and gasoline fuel market. Given efficient households that minimize the cost of operating automobiles, recent vehicle technology that improves blended fuel substitution, and typical market conditions of the last five years, blended fuels with 20% ethanol concentration could occupy a volume of 82.2 billion gallons in a 138.3 billion gallon gasoline market. The consumer welfare gain associated with blended fuel is $15.9 billion annually for US consumers, or about $1000 over the life of a vehicle. The ethanol demand associated with a voluntary blended fuel market is 16.4 BGY, slightly more than the conventional component of the Renewable Fuels Standard. It is time to replace the corn RFS with a free market. But an active competition policy in the fuel marketing system may also be required. Intervention for the impending Biomass Ethanol Industry, such as a subsidy or an exemption a carbon tax, may also be in order. - Highlights: • Competiveness of 20% ethanol blends replacing gasoline is examined. • Households can reduce costs by $1000 over vehicle life with ethanol blend. • Blended fuel could gain a 60% share in a voluntary US gasoline market. • US ethanol supply in a voluntary market would match current mandated output.

  4. Large Hybrid Energy Systems for Making Low CO2 Load-Following Power and Synthetic Fuel

    International Nuclear Information System (INIS)

    Cherry, Robert S.; Boardman, Richard D.; Aumeier, Steven

    2012-01-01

    Hybrid energy systems using nuclear heat sources can economically produce load-following electrical power by exploiting the surplus generation capacity available at night or seasonally to make synthetic fuel. Vehicle fuel is the only current energy use large enough to absorb all the energy capacity that might be diverted from the power industry, and its ease of storage obviates problems with discontinuous synfuel production. The potential benefits and challenges of synfuels integration are illustrated by the production of methanol from natural gas (as a source of carbon) using steam from a light water nuclear power reactor which is assumed to be available in accord with a year's worth of power demand data. Methanol's synthesis process is easily adapted to using 300 C heat from a light water reactor and this simple compound can be further processed into gasoline, biodiesel, or dimethyl ether, fuels which can be used with the current vehicle fleet. A supplemental feed to the methanol process of natural gas (for energy) allows operation at constant full rate when the nuclear heat is being used to produce electrical power. The higher capital costs of such a system are offset by a lower cost of heat and power production from a large base load type of plant and by reduced costs associated with much lower CO2 emissions. Other less tangible economic benefits of this and similar hybrid systems include better use of natural resource for fuels and greater energy services security from the domestic production of vehicle fuel.

  5. The prospects of synthetic biology for the production of fuel from biomass

    2013-01-01

    When applied to engineering the metabolism of microorganisms, synthetic biology produces a broad spectrum of biomolecules from carbohydrates and, in the near future, from the biomass in general. The markets for biofuels and for chemicals are thus hooked up through a common technological core. Synthetic biology also opens new possibilities for switching from different types of biomass to different products, thus allowing for more flexibility in development strategies and eventually in industrial operations. This opening is welcomed even though the economic and societal environments hardly favors biofuels. A few more years of research and development are needed to bring these new possibilities to industrial maturity. Advanced biofuels will pass the threshold at which they become profitable and will no longer need subsidies. (author)

    Since fuel oil meeting the requirements of current petroleum products can be produced by SASOL F-T synthetic process, the manufacturing process of hydrocarbon fuel oil from the coal-derived synthesis gas, downstream processes are being successively investigated. Mobile M-gasoline, MTG, process which produces gasoline from the natural gas-derived synthesis gas through methanol went into commercial operation in New Zealand in 1986. Although the gasoline suffices the quality of commercial gasoline by both fixed bed and fluidized bed systems, the price and service life of catalyst and control of by-product durene must be improved. Any STG processes have not been completed yet and the yield and quality of gasoline are inferior to those of gasoline produced by the MTG process. Applying two-stage process, the STG process will be more economically effective.(21 refs, 4 figs, 10 tabs)

    Rich-lean combustor concepts designed to enhance rich combustion chemistry and increase combustor flexibility for NO(x) reduction with minimally processed fuels are examined. Processes such as rich product recirculation in the rich chamber, rich-lean annihilation, and graduated air addition or staged rich combustion to release bound nitrogen in steps of reduced equivalence ratio are discussed. Variations to the baseline rapid quench section are considered, and the effect of residence time in the rich zone is investigated. The feasibility of using uncooled non-metallic materials for the rich zone combustion construction is also addressed. The preliminary results indicate that rich primary zone staged combustion provides environmentally acceptable operation with residual and/or synthetic coal-derived liquid fuels

  10. The nuclear fuel market of the next century

    An attempt is made to forecast the state of the nuclear fuel market 10 and 25 years ahead in 2005 and 2015. This is dependent on predicting the status of nuclear power. By 2005, nuclear power will either be phasing out or in resurgence. Although there will be increased demand for electricity, nuclear power will have to show favourable economics for new plants to be built in the USA and Europe, and in the USA high-level radioactive waste disposal will also need to be on a sound footing. Nuclear power may have reached saturation in the traditionally nuclear prone countries of Asia. A major factor in the uranium market will be the availability of high enriched uranium. By 2015 there should be a clear picture of the future of nuclear power which will either be on an upsurge or well into phase-out. Given an upsurge, there would be adequate incentive for the uranium industry to be revitalised. In uranium enrichment, gaseous diffusion will be virtually eliminated in favour of centrifuge and newer technologies. Commercial grade nuclear fuel derived from weapons could still be continuing to play a key role in the market. (UK)

    Toyota's introduction of a hybrid electric vehicle (HEV) named ''Prius'' in Japan and Honda's proposed introduction of an HEV in the United States have generated considerable interest in the long-term viability of such fuel-efficient vehicles. A performance and cost projection model developed entirely at Argonne National Laboratory (ANL) is used here to estimate costs. ANL staff developed fuel economy estimates by extending conventional vehicle (CV) modeling done primarily under the National Cooperative Highway Research Program. Together, these estimates are employed to analyze dollar costs vs. benefits of two of many possible HEV technologies. We project incremental costs and fuel savings for a Prius-type low-performance hybrid (14.3 seconds zero to 60 mph acceleration, 260 time) and a higher-performance ''mild'' hybrid vehicle, or MHV (11 seconds 260 time). Each HEV is compared to a U.S. Toyota Corolla with automatic transmission (11 seconds 260 time). The base incremental retail price range, projected a decade hence, is $3,200-$3,750, before considering battery replacement cost. Historical data are analyzed to evaluate the effect of fuel price on consumer preferences for vehicle fuel economy, performance, and size. The relationship between fuel price, the level of change in fuel price, and consumer attitude toward higher fuel efficiency is also evaluated. A recent survey on the value of higher fuel efficiency is presented and U.S. commercial viability of the hybrids is evaluated using discount rates of 2090 and 870. Our analysis, with our current HEV cost estimates and current fuel savings estimates, implies that the U.S. market for such HEVS would be quite limited.

  12. Matched conversion sales in the nuclear fuel market

    1996-01-01

    The negotiations leading up to the Suspension Agreement with Russia focused solely on uranium and SWU, leaving conversion in its traditional role as the overlooked constituent of the fuel cycle. In fact, the initial agreement did not even distinguish U 3 O 8 from UF 6 ; it effectively ignored the conversion component contained in UF 6 and the possibility of matched conversion sales. After some criticism from ConverDyn and others, The US Department of Commerce issued a clarification, confirming that all three major components of the fuel cycle can be sold under matched sales agreements. However, matched conversion sales remain somewhat of an enigma as few have been done and the logistics are poorly understood. Nonetheless, in a conversion market where supply and demand are closely balanced, secondary supplies, including those from matched sales, will likely play an important role in the evolution of conversion prices

    For several years the European Union (E.U.) has been promoting the use of biofuels due to their potential benefits such as the reduction of dependence on foreign energy imports (the raw materials can be produced within the E.U.), the more stable fossil fuel prices (they can replace fossil fuels on the market), the greenhouse gas (GHG) reduction (biofuels' raw materials fix CO 2 from the atmosphere) and the fact that they can represent an additional source of income for the primary sector (biofuels' raw materials are vegetables that can be grown and harvested). Despite the public aids (direct and indirect), biofuels are not competitive with fossil fuels at present, but it is possible that in the future the environment conditions change and biofuels might become competitive. It is difficult to assess whether this will happen or not, but it is possible to make an assessment of a future situation. This article presents two analyses with one objective: to determine if biofuels might become competitive in the future. The first analysis examines the dependencies of two quotations which have a strong relationship with fuels: the crude oil quotation and the CO 2 bond quotation. The analysis of these relationships may help to forecast the future competitiveness of biofuels. For instance, biofuels' future competitiveness will be higher if their raw material costs are not related to crude oil quotations or if they are related in a negative way (the higher the crude oil quotations the lower the raw material biofuels' cost). The second analysis focuses on the market penetration of biofuels in the Spanish market. There are data related to biofuels monthly consumption in Spain since 2007 and it is possible to know if biofuels are gaining market quota since then. (author)

    Widespread implementation of polymer electrolyte membrane fuel cell (PEMFC) powerplants for stationary and vehicular applications will be dependent in the near future on using readily available hydrocarbon fuels as the source of the hydrogen fuel. Methane and propane are ideal fuels for stationary applications, while methanol, gasoline, and diesel fuel are better suited for vehicular applications. Various means of fuel processing are possible to produce a gaseous fuel containing H{sub 2}, CO{sub 2} and CO. CO is a known electrocatalyst poison and must be reduced to low (10`s) ppm levels and CO{sub 2} is said to cause additional polarization effects. Even with no CO in the feed gas a H{sub 2}/CO{sub 2}/H{sub 2}O gas mixture will form some CO. Therefore, as a first step of developing a PEMFC that can operate for thousands of hours using a reformed fuel, we used an anode gas feed of 80% H{sub 2} and 20% CO{sub 2} to simulate the reforming of CH{sub 4}. To investigate the effect of reformate on cell performance and endurance, a single cell with an active area of 58 cm{sup 2} was assembled with a membrane electrode assembly (MEA) furnished by Texas A and M University using IGT`s internally manifolded heat exchange (IMHEX{sup TM}) design configuration. The MEA consisted of a Nafion 112 membrane with anode and cathode Pt catalyst loadings of 0.26 and 1.46 mg/cm{sup 2}, respectively. The cell was set to operate on a synthetic reformate - air at 60 C and 1 atm and demonstrated over 5000 h of endurance with a decay rate of less than 1%/1000 h of operation. The cell also underwent four successful thermal cycles with no appreciable loss in performance. The stable performance is attributed to a combination of the IGT IMHEX plate design with its inherent uniform gas flow distribution across the entire active area and MEA quality. The effects of temperature, gas composition, fuel utilization (stoics) and thermal cycle on cell performance are described. (orig.)

    Today's electric vehicles are almost exclusively powered by lithium-ion batteries, but there is a long way to go before electric vehicles become dominant in the global automotive market. In addition to policy support, widespread deployment of electric vehicles requires high-performance and low-cost energy storage technologies, including not only batteries but also alternative electrochemical devices. Here, we provide a comprehensive evaluation of various batteries and hydrogen fuel cells that have the greatest potential to succeed in commercial applications. Three sectors that are not well served by current lithium-ion-powered electric vehicles, namely the long-range, low-cost and high-utilization transportation markets, are discussed. The technological properties that must be improved to fully enable these electric vehicle markets include specific energy, cost, safety and power grid compatibility. Six energy storage and conversion technologies that possess varying combinations of these improved characteristics are compared and separately evaluated for each market. The remainder of the Review briefly discusses the technological status of these clean energy technologies, emphasizing barriers that must be overcome.

  17. Synthetic fuels development in Kentucky: Four scenarios for an energy future as constructed from lessons of the past

    Science.gov (United States)

    Musulin, Mike, II

    The continued failure of synthetic fuels development in the United States to achieve commercialization has been documented through the sporadic periods of mounting corporate and government enthusiasm and high levels of research and development efforts. Four periods of enthusiasm at the national level were followed by waning intervals of shrinking financial support and sagging R&D work. The continuing cycle of mobilization and stagnation has had a corresponding history in Kentucky. To better understand the potential and the pitfalls of this type of technological development the history of synthetic fuels development in the United States is presented as background, with a more detailed analysis of synfuels development in Kentucky. The first two periods of interest in synthetic fuels immediately after the Second World War and in the 1950s did not result in any proposed plants for Kentucky, but the third and fourth periods of interest created a great deal of activity. A theoretically grounded case study is utilized in this research project to create four different scenarios for the future of synthetic fuels development. The Kentucky experience is utilized in this case study because a fifth incarnation of synthetic fuels development has been proposed for the state in the form of an integrated gasification combined cycle power plant (IGCC) to utilize coal and refuse derived fuel (RDF). The project has been awarded a grant from the U.S. Department of Energy Clean Coal Technology program. From an examination and analysis of these periods of interest and the subsequent dwindling of interest and participation, four alternative scenarios are constructed. A synfuels breakthrough scenario is described whereby IGCC becomes a viable part of the country's energy future. A multiplex scenario describes how IGCC becomes a particular niche in energy production. The status quo scenario describes how the old patterns of project failure repeat themselves. The fourth scenario describes

    A detailed assessment of the major environmental constraints to siting a synthetic fuels industry and the results of that assessment are used to determine on a regional basis the potential for development of such an industry with minimal environmental conflicts. Secondly, the ability to mitigate some of the constraining impacts through alternative institutional arrangements, especially in areas that are judged to have a low development potential is also assessed. Limitations of the study are delineated, but specifically, the study is limited geographically to well-defined boundaries that include the prime coal and oil shale resource areas. The critical factors used in developing the framework are air quality, water availability, socioeconomic capacity, ecological sensitivity, environmental health, and the management of Federally owned lands.

    Geobacter-dominated biofilms can be selected under stringent conditions that limit the growth of competing bacteria. However, in many practical applications, such stringent conditions cannot be maintained and the efficacy and stability of these artificial biofilms may be challenged. In this work, biofilms were selected on low-potential anodes (-0.36 V vs Ag/AgCl, i.e. -0.08 V vs SHE) in minimal acetate or ethanol media. Selection conditions were then relaxed by transferring the biofilms to synthetic wastewater supplemented with soil as a source of competing bacteria. We tracked community succession and functional changes in these biofilms. The Geobacter-dominated biofilms showed stability in their community composition and electrochemical properties, with Geobacter sp. being still electrically active after six weeks in synthetic wastewater with power densities of 100±19 mW·m(-2) (against 74±14 mW·m(-2) at week 0) for all treatments. After six weeks, the ethanol-selected biofilms, despite their high taxon richness and their efficiency at removing the chemical oxygen demand (0.8 g·L(-1) removed against the initial 1.3 g·L(-1) injected), were the least stable in terms of community structure. These findings have important implications for environmental microbial fuel cells based on Geobacter-dominated biofilms and suggest that they could be stable in challenging environments.

    1982-01-01

    Two approaches for synthetic fuel production from coal are studied using Texas lignite as the feedstock. First, the gasification and liquefaction of coal are accomplished using Lurgi gasifiers and Fischer-Tropsch synthesis. A 50 000 barrel/day facility, consuming 13.7 million tonne/yr (15.1 million ton/yr) of lignite, is considered. Second, a nuclear-assisted coal conversion approach is studied using a very high temperature gas-cooled reactor with a modified Lurgi gasifier and Fischer-Tropsch synthesis. The nuclear-assisted approach resulted in a 35% reduction in coal consumption. In addition, process steam consumption was reduced by one-half and the oxygen plants were eliminated in the nuclear assisted process. Both approaches resulted in a synthetic oil price higher than the March 1980 imported price of $29.65 per barrel: $36.15 for the lignite-only process and $35.16 for the nuclear-assisted process. No tax advantage was assumed for either process and the utility financing method was used for both economic calculations

    1980-01-01

    A simple analytic model is used to examine economic constraints of a fusion-fission complex in which a portion of a thermal energy is used for producing synthetic fuel (synfuel). Since the values of many quantities are not well-known, a parametric analysis has been carried out for testing the sensitivity of the synfuel production cost in relation to crucial economic and technological quantities (investment costs of hybrid and synfuel plants, energy multiplication of the fission blanket, recirculating power fraction of the fusion driver, etc.). In addition, a minimum synfuel selling price has been evaluated, from which the fission-fusion-synfuel complex brings about a higher economic benefit than does the fusion-fission hybrid entirely devoted to fissile-fuel and electricity generation. This paper describes the energy flow diagram of fusion-fission synfuel concept, express the revenue-to-cost formulation and the breakeven synfuel selling price. The synfuel production cost given by the model is evaluated within a range of values of crucial parameters. Assuming an electric cost of 2.7 cents/kWh, an annual investment cost per energy unit of 4.2 to 6 $/FJ for the fusion-fission complex and 1.5 to 3 $/GJ for the synfuel plant, the synfuel production cost lies between 6.5 and 8.5 $/GJ. These production costs can compete with those evaluated for other processes. The study points out a potential use of the fusion-fission hybrid reactor for other than fissile-fuel and electricity generation. (orig.) [de

    Two forces are restructuring the world's electricity industry: commercialization and globalization. Commercialization, the focus of this paper, is the introduction of competition into electric generation and the dissolution of existing government or private electric generating monopolies. The winds of change now sweeping through the electric generating business are altering many old assumptions, one of which is the choice of coal as the preferred baseload fuel. In markets where natural gas is available, and both the gas and the electricity industries have been liberalized and opened to competition, there is a growing tendency for independent power producers to choose gas over coal. As well, technological advances have tended to favour the gas industry. Electricity generation by fuel type is discussed for the United States, United Kingdom, Asia and Australia, as well as the implications for the coal industry. (author). 2 tabs., 11 figs

    Mixed-oxide (MOX) fuel is nearing maturity as a fuel supply option. This paper briefly reviews the history and current status of the MOX fuel market, including the projected increase in demand for MOX fuel as more plutonium becomes available from the operation of commercial irradiated fuel reprocessing plants in Europe. The uncertainties of such projected demand are discussed, together with the anticipated requirements from the next generation of MOX fabrication plants. The impact of the growing demand for MOX fuel is assessed in the traditional sectors of the uranium fuel cycle. Finally, the author turns to a generalized treatment of the economic aspects of MOX fuel utilization, showing the financially attractive regimes of MOX use which will benefit nuclear power utilities and continue to ensure that MOX fuel can consolidate its position as a mature fuel supply option in those countries that have opted to recycle their spent fuel

    This study was undertaken to identify the ototoxic potential of two jet fuels presented alone and in combination with noise. Rats were exposed via a subacute inhalation paradigm to JP-8 jet fuel, a kerosene-based fuel refined from petroleum, and a synthetic fuel produced by the Fischer-Tropsch (FT) process. Although JP-8 contains small ( approximately 5%) concentrations of aromatic hydrocarbons some of which known to be ototoxic, the synthetic fuel does not. The objectives of this study were to identify a lowest observed adverse effect level and a no observed adverse effect level for each jet fuel and to provide some preliminary, but admittedly, indirect evidence concerning the possible role of the aromatic hydrocarbon component of petroleum-based jet fuel on hearing. Rats (n = 5-19) received inhalation exposure to JP-8 or to FT fuel for 4 h/day on five consecutive days at doses of 500, 1000, and 2000 mg/m(3). Additional groups were exposed to various fuel concentrations followed by 1 h of an octave band of noise, noise alone, or no exposure to fuel or noise. Significant dose-related impairment in the distortion product otoacoustic emissions (DPOAE) was seen in subjects exposed to combined JP-8 plus noise exposure when JP-8 levels of at least 1000 mg/m(3) were presented. No noticeable impairment was observed at JP-8 levels of 500 mg/m(3) + noise. In contrast to the effects of JP-8 on noise-induced hearing loss, FT exposure had no effect by itself or in combination with noise exposure even at the highest exposure level tested. Despite an observed loss in DPOAE amplitude seen only when JP-8 and noise were combined, there was no loss in auditory threshold or increase in hair cell loss in any exposure group.

    We examined the co-evolution of the transportation, and electricity and heat generation sectors in the Netherlands until 2040 using a MARKAL bottom-up cost optimisation model. All scenario variants investigated indicate a switch away from crude oil-based diesel and petrol for transportation. Lowest overall CO 2 abatement cost is achieved by accommodating transportation first and using relatively expensive options for emissions reduction in electricity generation if needed. Biomass and carbon capture and storage (CCS) are used to full potential. Transportation CO 2 emissions are reduced by switching to ethanol or bio-based synthetic fuels combined with CCS, and series hybrid cars if needed. Depending on the availability of biomass and carbon storage capacity, electricity is produced from biomass, coal with CCS, or wind complemented with natural gas. Indirect greenhouse gas emissions rise to 34-54% of national emissions in 2040. The difference in annual investment required between the scenario variants with and without CO 2 emissions reductions of 68% by 2040 is 4-7 billion euro/year, or 0.5-1.2% of projected GDP. Investment costs are mostly determined by the cost of cars and electricity generation capacity. We observe competition for limited biomass supply and CO 2 storage capacity between the transportation and power sectors.

    This study was a part of the EU R and D programme 1994-1998: Nuclear Fission Safety, entitled `Source term for performance assessment of spent fuel as a waste form`. The research carried out at VTT Chemical Technology was focused on the effects of granitic groundwater composition and redox conditions on UO{sub 2} solubility and dissolution mechanisms. The synthetic groundwater compositions simulated deep granitic fresh and saline groundwaters, and the effects of the near-field material, bentonite, on very saline groundwater. Additionally, the Spanish granite/bentonite water was used. The redox conditions (Eh), which are obviously the most important factors that influence on UO{sub 2} solubility under the disposal conditions of spent fuel, varied from strongly oxidising (air-saturated), anaerobic (N{sub 2}, O{sub 2} < l ppm) to reducing (N{sub 2}, low Eh). The objective of the air-saturated dissolution experiments was to yield the maximum solution concentrations of U, and information on the formation of secondary phases that control the concentrations, with different groundwater compositions. The static batch solubility experiments of long duration (up to 1-2 years) were performed using unirradiated UO{sub 2} pellets and powder. Under anaerobic and reducing conditions, the solubilities were also approached from oversaturation. The results of the oxic, air-saturated dissolution experiments with UO{sub 2} powder showed that the increase in the salinity (< 1.7 M) had a minor effect on the measured steady-state concentrations of U. The concentrations, (1.2 ...2.5) x 10{sup -5} M, were at the level of the theoretical solubility of schoepite or another uranyl oxide hydrate, e.g. becquerelite (possibly Na-polyuranate). The higher alkalinity of the fresh (Allard) composition increased the aqueous U concentration. Only some kind of oxidised U-phase (U{sub 3}O{sub 8}-UO{sub 3}) was identified with XRD when studying possible secondary phases after the contact time of one year

The report catalogues and describes the model assumptions, computational methodology, parameter estimation techniques, model source code, and forecast results generated through the synthesis and scenario development based on these components. This document serves four purposes. First, it is a reference document providing a detailed description of the model for reviewers and potential users of the EFD including energy experts at the Energy Information Administration (EIA), other Federal agencies, state energy agencies, private firms such as utilities and consulting firms, and non-profit groups such as consumer and environmental groups. Second, this report meets the legal requirement of the Energy Information Administration (EIA) to provide adequate documentation in support of its statistical and forecast reports. Third, it facilitates continuity in model development by providing documentation which details model enhancements that were undertaken for AE097 and since the previous documentation. Last, because the major use of the EFD is to develop forecasts, this documentation explains the calculations, major inputs and assumptions which were used to generate the AE097.

    Glass ceramics (i.e., glasses subjected to controlled crystallization) with synthetic titanite as the major crystalline phase are being considered as potential hosts for the radioactive wastes arising from possible future reprocessing of nuclear fuel in Canada. In order to assess the stability of titanite in the anticipated environment of a disposal vault sited 500-1000 m deep within a granitic pluton in the Canadian Shield, leaching experiments have been performed with natural and synthetic titanite, using a synthetic groundwater whose composition is based on findings from a recent borehole-survey. The results are in qualitative agreement with calculations of solution equilibria for titanite and its main alteration products, and indicate that titanite should be stable and suffer no net leaching under anticipated conditions in the vault

    Full Text Available The main aim of the research is to continue the studies on promising technologies of coal conversion into synthetic liquid fuel (methanol. The object of study is the plants for combined production of electricity and synthetic liquid fuel (PCPs, which are eco-friendly and more efficient as compared to the plants for separate production. The previous studies on PCPs consider the systems for fine cleaning of gasification products in a simplified way. This study presents the detailed mathematical modeling of the aforementioned systems and determines the values of energy consumption and investment in them. The obtained values are used to carry out the optimization studies and find the optimal parameters of PCPs with different degree of CO2 removal from gasification products providing fine cleaning of gasification products from H2S.

    The commercialization of natural gas reserves via synthesis to liquid products is a particularly active area of research which could permit this energy carrier to penetrate new markets. This study provides a global perspective of developments in this area, the technology and its economic and environmental implications, completed by a full review of current projects. A number of research centres as well as engineering companies and oil and gas companies are engaged in significant research programmes to improve the processes employed in the gas to liquids chain. This section provides a complete picture of the recent technology developments and the areas for potential future improvement.The research activities of each organisation and the process scheme employed are described.The implications of the major differences in the technologies are reviewed. Each step in the GTL chain-feed preparation, syngas production, the Fischer-Tropsch process and product work up is covered. The relationship between the products from the process and the technology employed is discussed. Aside from the technological aspects, the economics of the GTL process remains the major hurdle to be overcome if this technology is to be more widely utilized.The key parameters affecting the economics of GTL developments are the cost of natural gas, capital investments and the impact of economies of scale.The key driver for the oil and gas companies is to provide a way of commercializing natural gas reserves when other means, such as pipeline transportation or LNG, are not viable. This section provides a review of the costs and economics of the GTL chain taking into account the process configuration and resulting capital costs, the products produced, the effect of scale and other relevant factors.The aim is to provide an understanding of the economic factors affecting the GTL chain. Middle distillate fuels produced from the GTL process are sulphur and aromatics free and will be attractive for use in the

    Stallard, S.; Anderson, A.; Schick, J.

    1998-01-01

    Worldwide, one can see that competition, deregulation, or at a minimum, a closer focus on the overall economies of power generation is stimulating change within the power sector. Power generation markets are becoming liberalized providing for independent power producers and, in some cases, providing third-party access to the grid. In the US, fuel costs are being transformed from a pass-through expense to the consumer to one of a strategic asset or liability. In every case, fuel quality, fuel-related costs, and managing the fuel purchasing process are key factors in the overall efficiency and financial performance on the power generator. This paper illustrates how effective fuel management requires that the utility or GenCo improve upon historical fuel management/purchasing practices to lower overall generation costs and address the opportunities present in the power and fuel markets. Key framework/principles to be discussed include: Tighter coupling of fuel purchasing, short-term planning, and dispatch functions. Effective planning to link purchased fuel to system demand forecasts, consider contract/transportation constraints/economics, evaluate alternative sources, and consider fuel mix strategies (e.g., between sport, contract, and various regions/qualities). Tools and processes needed to support the new business environment such as fuel impact analysis, application of integrated fuel evaluation/management systems, market forecasting, purchasing, and the role of fuel management in energy trading. Flexibility to support optimal purchasing strategies including shorter purchase cycles, special buys, buys for third parties, and coal tolling. This framework would be discussed using examples from the US, UK, European, and Pacific Rim markets

    2005-01-01

    A feasibility study on the market potential of 2-wheel fuel cell vehicles in Shanghai, China was presented. The Chinese government has recently invested a considerable amount of money in fuel cell technology research programs. However, 2-wheel fuel cell vehicles are not included in the program's plans. Considering future transportation models and examining market demand, it was anticipated that the 2-wheel fuel cell vehicles have an enormous market potential in China. An outline of market demands was presented. Issues concerning technological availability, hydrogen supply availability and government policies were considered. An economic overview of Shanghai was presented. International trends in fuel cell vehicles were reviewed, as well as issues concerning traffic and environmental impacts. Recommended policies for development were presented. Supply and demand issues were also considered. At present, 2-wheelers are only at the conceptual and demonstration stage. A graduated commercial framework for fuel cell bicycles and scooters was presented, which included initial production and medium scale production phases as well as the development of a hydrogen supply network over a period of 9 years. It was concluded that, as there are more than 9 million bicycles and over 300,000 motorcycles in Shanghai, there is potentially a huge market and a good base the development phases and gradual commercialization of 2-wheel fuel cell vehicles. 9 refs., 4 tabs., 3 figs

  2. Fuel switching? Demand destruction? Gas market responses to price spikes

    International Nuclear Information System (INIS)

    Lippe, D.

    2004-01-01

    This presentation defined fuel switching and addressed the issue regarding which consumers have the capability to switch fuels. In response to short term price aberrations, consumers with fuel switching capabilities reduce their use of one fuel and increase consumption of an alternative fuel. For example, natural gas consumption by some consumers declines in response to price spikes relative to prices of alternative fuels. This presentation also addressed the issue of differentiating between fuel switching and demand destruction. It also demonstrated how to compare gas prices versus alternative fuel prices and how to determine when consumers will likely switch fuels. Price spikes have implications for long term trends in natural gas demand, supply/demand balances and prices. The power generating sector represents a particular class of gas consumers that reduce operating rates of gas fired plants and increase operating rates of other plants. Some gas consumers even shut down plants until gas prices declines and relative economies improve. Some practical considerations for fuel switching include storage tank capacity, domestic refinery production, winter heating season, and decline in working gas storage. tabs., figs

    Ekbom, Tomas; Berglin, Niklas; Loegdberg, Sara [Nykomb Synergetics AB, Stockholm (Sweden)

    2005-06-15

    The present project presents additional results to the former BLGMF project, which investigate Black Liquor Gasification with Motor Fuels (BLGMF) production. The objectives were to investigate, based on the KAM 2 program Ecocyclic Pulp Mill (2,000 ADt/day of pulp) the feasibility of synthetic fuels production. Specifically the route to Fischer-Tropsch diesel fuels is investigated as comparison to earlier work on methanol/DME. As modern kraft pulp mills have a surplus of energy, they could become key suppliers of renewable fuels. It is thus of great interest to convert the spent cooking product 'black liquor' to an energy carrier of high value. The resulting biomass-to-fuel energy efficiency when only biomass is used as an external energy source was 43% for FTD or 65% for FT products compared with 66% for methanol and 67% for DME. The FTD calculation is considerably more complicated and based on assumptions, therefore the uncertainty is higher. Would the diesel be taken out with a T95% of 320 deg C the FTD efficiency would be 45%. FT synthesis also opens up a possibility to produce e.g. lube oils from waxes produced. The total net FT-products output equals 4115 barrels/day. The FTD production cost is calculated as the energy share of the total production cost and assumes an offset of naphtha covering its own costs, where it is essential that it finds a market. Assuming same petrol (methanol) and diesel (DME, FTD) costs for the consumer the payback time were 2.6, 2.9 and 3.4 years with an IRR of 40%, 45% and 30%, respectively. In conclusion, there are necessary resources and potential for large-scale methanol (or DME, FTD) production and substantial economic incentive for making plant investments and achieving competitive product revenues.

    The development of the nuclear fuel elements' industry is analyzed, both in the present and projected world market, up to the year 2000, in the light of the situation affecting the nucleoelectric industry. By means of the offer/demand function, an analysis is made of the behaviour of the fuel elements' market throughout the fuel cycle structure. The regional unbalances between availability and demand of uranium resources are considered, as well as the factors having an unfavorable incidence on the fuel cycle's economic equation. The economic structure to be used for the calculation of the nucleoelectric generating cost is presented, in order to situate, within said nuclear economy, the component corresponding to the fuel cycle cost. Emphasis is placed on the 'front end' stages of the fuel cycle, but also considering those stages belonging to the 'back end'. Argentina's fuel elements market and its present and projected nucleoelectric park are analyzed, indicating their relative position in the world market. (R.J.S.) [es

    2004-03-01

    Biofuel production from wood is an interesting option for the energetic use of wood. Various bio fuels could be produced from woody biomass, such as methanol, Fischer-Tropsch (FT) fuels, methane or hydrogen. FT liquids and bio-SNG can be distributed and used via existing infrastructures and therefore fit best today's fossil infrastructure. On an assessment basis from primary to mechanical energy both fuels have pros and cons. For the consolidation of crucial information, i.e. production cost, demonstration plants of transportation fuels are needed. Based on such plants, a detailed evaluation of both fuel chains will be possible. (author)

    2014-08-01

    Full Text Available The comparison between Thermal Polyaspartate Anion, TPA, and natural resin in their effect on the improvement of the physicochemical properties of both conventional diesel and JP8 fuels is the main scope of this work. Specifically, both studied materials were used dehydration agents in order to increase the physicochemical properties of both treated fuels. The higher amount of the removed water was obtained when used the natural resin as adsorbent material. In this case the water concentration decreased into diesel up to 68.66 % and more than 30 % in the case of jet fuel (JP8. This water removal improves the studied physicochemical properties of both studied fuels, diesel and JP8, for example up to 633 J/g (using natural resin as dehydration agent (removable additive and 1040 J/g (using TPA as dehydration agent for the heat of combustion. Overall, the proposed method can be used in a simple fuel cleaning process using a metal mesh vessel of synthetic TPA polymer or natural resin. The higher water/humidity removal amount in conjunction with the very low price of the natural resin makes this material more promising for the up scaling of the proposed technique in the near future.

    The wood-fuel market benefits from the present day development of renewable energy sources, both in the individual residential sector where wood-fuel is becoming a main space-heating solution and not only an auxiliary one, and in the collective residential, tertiary and industrial sectors where more than 1850 wood-burning facilities have been implemented in 6 years under the impulse of the wood-fuel development plan. Sales have raised by 40% in the residential sector in 2006 and a 50% increase of renewable energy sources is expected in the heat generation sector from now to 2010. This article presents the main trends of the French wood-fuel market and the existing offer of wood-fuel boilers. (J.S.)

  12. Redundancy of Supply in the International Nuclear Fuel Fabrication Market: Are Fabrication Services Assured?

    Seward, Amy M.; Toomey, Christopher; Ford, Benjamin E.; Wood, Thomas W.; Perkins, Casey J.

    2011-01-01

    For several years, Pacific Northwest National Laboratory (PNNL) has been assessing the reliability of nuclear fuel supply in support of the U.S. Department of Energy/National Nuclear Security Administration. Three international low enriched uranium reserves, which are intended back up the existing and well-functioning nuclear fuel market, are currently moving toward implementation. These backup reserves are intended to provide countries credible assurance that of the uninterrupted supply of nuclear fuel to operate their nuclear power reactors in the event that their primary fuel supply is disrupted, whether for political or other reasons. The efficacy of these backup reserves, however, may be constrained without redundant fabrication services. This report presents the findings of a recent PNNL study that simulated outages of varying durations at specific nuclear fuel fabrication plants. The modeling specifically enabled prediction and visualization of the reactors affected and the degree of fuel delivery delay. The results thus provide insight on the extent of vulnerability to nuclear fuel supply disruption at the level of individual fabrication plants, reactors, and countries. The simulation studies demonstrate that, when a reasonable set of qualification criteria are applied, existing fabrication plants are technically qualified to provide backup fabrication services to the majority of the world's power reactors. The report concludes with an assessment of the redundancy of fuel supply in the nuclear fuel market, and a description of potential extra-market mechanisms to enhance the security of fuel supply in cases where it may be warranted. This report is an assessment of the ability of the existing market to respond to supply disruptions that occur for technical reasons. A forthcoming report will address political disruption scenarios.

    Forklift propulsion systems and distributed power generation are identified as potential fuel cell applications for near-term markets. This analysis examines fuel cell forklifts and distributed power generators, and addresses the potential energy and environmental implications of substituting fuel-cell systems for existing technologies based on fossil fuels and grid electricity. Performance data and the Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET) model are used to estimate full fuel-cycle emissions and use of primary energy sources. The greenhouse gas (GHG) impacts of fuel-cell forklifts using hydrogen from steam reforming of natural gas are considerably lower than those using electricity from the average U.S. grid. Fuel cell generators produce lower GHG emissions than those associated with the U.S. grid electricity and alternative distributed combustion technologies. If fuel-cell generation technologies approach or exceed the target efficiency of 40%, they offer significant reduction in energy use and GHG emissions compared to alternative combustion technologies.

    Science.gov (United States)

    van der Giesen, Coen; Kleijn, René; Kramer, Gert Jan

    2014-06-17

    Within the context of carbon dioxide (CO2) utilization there is an increasing interest in using CO2 as a resource to produce sustainable liquid hydrocarbon fuels. When these fuels are produced by solely using solar energy they are labeled as solar fuels. In the recent discourse on solar fuels intuitive arguments are used to support the prospects of these fuels. This paper takes a quantitative approach to investigate some of the claims made in this discussion. We analyze the life cycle performance of various classes of solar fuel processes using different primary energy and CO2 sources. We compare their efficacy with respect to carbon mitigation with ubiquitous fossil-based fuels and conclude that producing liquid hydrocarbon fuels starting from CO2 by using existing technologies requires much more energy than existing fuels. An improvement in life cycle CO2 emissions is only found when solar energy and atmospheric CO2 are used. Producing fuels from CO2 is a very long-term niche at best, not the panacea suggested in the recent public discourse.

    2011-01-01

    To investigate how fuel economy is valued in the Indian car market, we compute the cost to Indian consumers of purchasing a more fuel-efficient vehicle and compare it to the benefit of lower fuel costs over the life of the vehicle. We estimate hedonic price functions for four market segments (petrol hatchbacks, diesel hatchbacks, petrol sedans, and diesel sedans) to compute 95% confidence intervals for the marginal cost to the consumer for an increase in fuel economy. We find that the associated present value of fuel savings falls within the 95% confidence interval for most specifications, in all market segments, for the years 2002 through 2006. Thus, we fail to consistently reject the hypothesis that consumers appropriately value fuel economy. - Highlights: → We examine the tradeoffs faced by new vehicle consumers in India. → We use hedonic price functions and instrumental variables. → We find no support for the hypothesis that consumers undervalue fuel economy. → Some consumers are willing to forgo substantial potential savings to own their preferred vehicle.

    2007-01-01

    Global concerns about fossil fuel stocks and security of supply have stimulated governments and industry to explore the development of alternative sources of energy. This has led to the emergence of liberalised markets for energy and the growth of de-centralised generation and distribution systems. Within this context, the use of a sustainable technology, such as fuel cells, as a generator of heat and electricity for the residential market, is a significant market opportunity. Using a set of framework conditions to explain the diffusion of renewable energy technologies, this paper analyses recent developments in four leading industrial countries, and concludes that Japan and Germany are competing to be the lead country for the introduction of this technology. In the process, we highlight the impact of government and the extent to which the development of a fuel cell industry is being driven by incumbent large firms acting independently or in collaboration with a range of other companies across the value chain.

    The European Union develops common EU policy and strategy on biofuels and sustainable bio-economy through several documents. The encouragement of biofuel's consumption is therefore the obligation of each EU member state. The situation in Slovenian fuel market is presented and compared with other EU countries in the frame of prescribed values from EU directives. Diesel is the most common fuel for transportation needs in Slovenia. The study was therefore performed on diesel. The sampling net was determined in accordance with the fuel consumption statistics of the country. 75 Sampling points were located on different types of roads. The quantity of bio-component in diesel samples was determined by direct LSC method through measurement of C-14 content. The measured values were in the range from 0 up to nearly 6 mass percentage of bio-component in fuel. The method has proved to be appropriate, suitable and effective for studies on the real fuel market. - Highlights: • The direct LSC method was tested and applied on real fuel samples from the Slovenian market. • The results of the study are comparable with the findings of official of EUROSTAT's report. • Comparison to other EU member states and EU directive prescription was performed

    An attempt is made to study the interaction process that occurs between petroleum products and the remainder of the fuel market. Petroleum competes with electricity, gas, and coal as a source of fuel, and an assessment is made of the demand elasticities of its place in the fuel market. In the U.K. fuel market the question is to what extent petroleum is a substitute or complement to the others. Petroleum consumption constituted 25 percent in 1960 of the total fuel consumption and has grown constantly since. The extent to which it changes depends upon its close substitutes. Which out of gas, coal, and electricity is, in fact, the closest substitute for petroleum; is it sensitive to price or to other things. In order to attempt to answer these questions, two models are presented. The first presents a straightforward linear equation for the demand for petroleum due to a change in total fuel consumption. This is then used in Model 2, which is basically the Slutsky equation, to obtain the mean substitution effect between petroleum and coal, gas and electricity. This, then, measures the net substitution or complementarity between petroleum and the commodities mentioned. 11 references.

    Fuel cells are both a longstanding and emerging technology for stationary and transportation applications, and their future use will likely be critical for the deep decarbonization of global energy systems. As we look into future applications, a key challenge for policy-makers and technology market forecasters who seek to track and/or accelerate their market adoption is the ability to forecast market costs of the fuel cells as technology innovations are incorporated into market products. Specifically, there is a need to estimate technology learning rates, which are rates of cost reduction versus production volume. Unfortunately, no literature exists for forecasting future learning rates for fuel cells. In this paper, we look retrospectively to estimate learning rates for two fuel cell deployment programs: (1) the micro-combined heat and power (CHP) program in Japan, and (2) the Self-Generation Incentive Program (SGIP) in California. These two examples have a relatively broad set of historical market data and thus provide an informative and international comparison of distinct fuel cell technologies and government deployment programs. We develop a generalized procedure for disaggregating experience-curve cost-reductions in order to disaggregate the Japanese fuel cell micro-CHP market into its constituent components, and we derive and present a range of learning rates that may explain observed market trends. Finally, we explore the differences in the technology development ecosystem and market conditions that may have contributed to the observed differences in cost reduction and draw policy observations for the market adoption of future fuel cell technologies. The scientific and policy contributions of this paper are the first comparative experience curve analysis of past fuel cell technologies in two distinct markets, and the first quantitative comparison of a detailed cost model of fuel cell systems with actual market data. The resulting approach is applicable to

  9. The optimal fuel mix and redistribution of social surplus in the Korean power market

    This paper investigates the difference between the optimal fuel mix incorporating a pre-installed generation capacity constraint and the actual fuel mix in the Korean power market. Since the restructuring of the market, the fuel mix has been determined partly by investors and partly by the Basic Plan for Long-Term Electricity Supply and Demand (BPE). Both the system marginal price (SMP), and the capacity payment (CP), which has been based on the fixed cost of a specific gas turbine generator, were intended to provide an investment incentive in the market; however, they did not bring about an optimal fuel mix in Korea. Under the circumstances of a shortage of base load generators, these generators may garner excessive profits due to a high SMP level. However, the adjustment scheme of profit between KEPCO and Gencos left scant profit for generators. This paper suggests that a contract is needed to create the appropriate profit and tax levels for these base load generators. The redistribution of profit improves equality between consumers and generators, and the proper margin creates incentives for base load technology investment in Korea. - Research highlights: → This paper aims to determine the optimal fuel mix in Korea and shows the difference between the optimal and actual fuel mix; → We discovered that the optimal fuel mix ratio should be 63.5%:20.5%:16.0%for nuclear energy, coal, and LNG, respectively; → Because the pre-installed capacity is taken as given, the optimal fuel mix under the given installed capacity is an addition of a new nuclear unit to the current fuel mix; → The additional profit above the profit margin in the BPE should be collected and redistributed to consumers; → While we provide an incentive to build nuclear and coal units in Korea, we also suggest that a contract is needed to guarantee the profit level for generators based on a government regulation constraint, the BPE, to achieve a fair treatment.

    In the recent few years the nuclear fuel market has changed dramatically. With the new freedoms in east European countries and the former Soviet Union the uranium production capabilities and potential deliveries of these countries attracted a lot of attention in western markets. However, with the gradual decline of the uranium production in eastern Europe and the steadily increasing marketing activities of the former Soviet Union the attention of the western market participants shifted more and more to the Soviets with their delivery potentials and marketing practices. More recently, in the course of 1991, the nuclear disarmament measures triggered discussions on the potential recycling of military material into the civil nuclear fuel cycle and the potential impacts on the market. Now, after the Soviet Union has been replaced by the Commonwealth of Independent States, many questions concerning the prospects for fuel supply from Russian and the Central Asian uranium producing republics to the Western World stir the nuclear fuel market

    'Full text:' Nuvera Fuel Cells, Inc. is a global leader in the development and advancement of multifuel processing and fuel cell technology. With offices located in Italy and the USA, Nuvera is committed to advancing the commercialization of hydrogen fuel cell power modules for industrial vehicles and equipment and stationary applications by 2006, natural gas fuel cell power systems for cogeneration applications by 2007, and on-board gasoline fuel processors and fuel cell stacks for automotive applications by 2010. Nuvera Fuel Cells Europe is ISO 9001:2000 certified for 'Research, Development, Design, Production and Servicing of Fuel Cell Stacks and Fuel Cell Systems.' In the chemical industry, one of the largest operating expenses today is the cost of electricity. For example, caustic soda and chlorine are produced today using industrial membrane electrolysis which is an energy intensive process. Production of 1 metric ton of caustic soda consumes 2.5 MWh of energy. However, about 20% of the electricity consumed can be recovered by converting the hydrogen byproduct of the caustic soda production process into electricity via PEM fuel cells. The accessible market is a function of the economic value of the hydrogen whether flared, used as fuel, or as chemical. Responding to this market need, we are currently developing large hydrogen fuel cell power modules 'Forza' that use excess hydrogen to produce electricity, representing a practical economic alternative to reducing the net electricity cost. Due for commercial launch in 2006, Forza is a low-pressure, steady state, base-load power generation solution that will operate at high efficiency and 100% capacity over a 24-hour period. We believe this premise is also true for chemical and electrochemical plants and companies that convert hydrogen to electricity using renewable sources like windmills or hydropower. The second near-term market that Nuvera is developing utilizes a 5.5 kW hydrogen fueled power module 'H 2 e

    This paper investigates diesel engine performance and exhaust emissions with marine gas oil (MGO) and a blend of MGO and synthetic diesel fuel. Ten per cent by volume of Fischer-Tropsch (FT), a synthetic diesel fuel, was added to MGO to investigate its influence on the diesel engine performance and emissions. The blended fuel was termed as FT10 fuel, while the neat (100 vol%) MGO was termed as MGO fuel. The experiments were conducted with a fourstroke, six-cylinder, turbocharged, direct injection, Scania DC 1102 diesel engine. It is interesting to note that all emissions including smoke (filter smoke number), total particulate matter (TPM), carbon monoxide (CO), total unburned hydrocarbon (THC), oxides of nitrogen (NOx) and engine noise were reduced with FT10 fuel compared with the MGO fuel. Diesel fine particle number and mass emissions were measured with an electrical low pressure impactor. Like other exhaust emissions, significant reductions in fine particles and mass emissions were observed with the FT10 fuel. The reduction was due to absence of sulphur and aromatic compounds in the FT fuel. In-cylinder gas pressure and engine thermal efficiency were identical for both FT10 and MGO fuels.

    The most acceptable alternative fuel for motor vehicles is compressed natural gas (CNG). An important potential source of such gas is coalbed methane, much of which is now being wasted. Although there are no technological impediments to the use of CNG it has not been adequately promoted for a variety of reasons: structural, institutional and for coalbed gas, legal. The benefits of using CNG fuel are manifold: clean burning, low cost, abundant, and usable in any internal combustion engine. Even though more than 30,000 CNG vehicles are now in use in the U.S.A., they are not readily available, fueling stations are not easily accessible, and there is general apathy on the part of the public because of negligence by such agencies as the Department of Energy, the Department of Transportation and the Environmental Protection Agency. The economic benefits of using methane are significant: 100,000 cubic feet of methane is equivalent to 800 gallons of gasoline. Considering the many millions of cubic feet methane wasted from coal mines conservation and use of this resource is a worthy national goal

    The existence of anti competitive conduct such as cartels would lead to a situation of high prices and profits harming competition and society in general. The methodology of economic analysis of evidence of cartel by the ANP in the resale market of fuels involves analysis of the behavior of the average prices of resale and distribution, the nominal average gross margin on resale, the coefficient of variation of prices of resale and distribution of fuel for a given period by the municipality. Combining the analysis of these elements, the ANP has suggested the investigation into possible cartels. This text aims to bring contributions for a better definition of the relevant market in the analysis of economic evidence in cartel in the market for resale of fuel and add elements currently not considered in the analysis of ANP and regulation of the sector. To this end, this article is organized into three sections besides the introduction and final consideration. The first section takes place at the constitution some myths about cartels thread reseller retailer of automotive fuel by analyzing the main causes leading to complaints by consumers. Then presents a conceptual analysis of relevant market, since this definition is essential to characterize anti-competitive practices of operations performed by companies holding market power, notably the formation of cartels. Finally, it is a discussion on how the action of the main bodies involved in dismantling of anti competitive practices in the industry. Expected to find results that work with greater integration between agencies to safeguard competition and better defining the relevant market segment for the resale of fuel. (author)

    U.S. Renewable Fuel Standard (RFS) is a mandatory policy for promoting the utilization of biofuels in road transpiration sector in order to reduce the country's dependency on foreign oil and greenhouse gas emissions. U.S. Environmental Protection Agency (EPA) defines the proportion of renewable fuels according to RFS annual target, and requests obligated parties such like fossil fuel refiner, blenders and importer in the U.S. to complete Renewable Volume Obligation (RVO) every year. Obligated parties prove they have achieved their RVO through a renewable fuels certification system, which generates Renewable Identification Numbers (RINs) for every gallon of qualified renewable fuels produced or imported into U.S., RINs is a key for tracking renewable fuel consumption, which in turn is a key for implementing the RFS in the U.S., separated RINs can be freely traded in market and obligated parties could fulfill their RVO through buying RINs from other stakeholders. This briefing paper highlights RFS policy implementing mechanism and marketing tracking, mainly describes importance of RINs, and the method for generating and tracking RINs by both government and fuels industry participants.

    1997-01-01

    US nuclear plants are now placing a great deal of importance on fuel performance and reliability because of their direct effect on a plant's capacity factor, availability, operating flexibility, outage duration, and worker exposure. This is reflected by utilities making fuel reliability a principal vendor evaluation criterion and making fuel performance an important bonus/penalty provision. Defect-free fuel, combined with ever improving design features, makes it possible for plants to operate at higher outputs while reducing operating and maintenance costs. Higher electrical output at lower cost is essential for US nuclear plants to meet the expected competition in a deregulated market. Through continued investment in manufacturing improvements and a vigilant, systematic design process, ABB's nuclear fuel has contributed to helping its nuclear utility customers reduce their cost of doing business.

    Full Text Available In this paper, we constructed a theoretical model of strategic pricing behavior of the players in a Polish wholesale fuel market. This model is consistent with the characteristics of the industry, the wholesale market, and the players. The model is based on the standard methodology of repeated games with a built-in adjustment to a focal price, which resembles the Import Parity Pricing (IPP mechanism. From the equilibrium of the game, we conclude that the focal price policy implies a parallel pricing strategic behavior on the market.

    The modification of traditional policies in nuclear business of Spanish Electrical Utilities, to meet new regulations is presented in this paper. It would be remarkable the influence of a new environment of significant economical transformation, which show us utilities affected by reorganization processes to face market demands. We will pay special attention to those activities involved in nuclear fuel management. Focusing in the field of Enriched Uranium supply, ENUSA, a state owned company, according to legal framework, played the role of sole supplier. The liberalization of primary energy sources was the turning point that triggered a process of changes. Now, the utilities rule the overall strategy and, not surprisingly they do definitively it is not. The new regulations tend to create conditions for a truly free market. So, competitiveness has become the magic word for almost all electricity producers. But in our case, the first question to be answered should be if free market does really mean a threat for us, or if it is just and external reference that puts no real pressure in our future plans. Lets remember that nuclear fuel cost in Spain is much lower than any other fuel cost. The working model we have defined is oriented to get benefit from market opportunities, improve flexibility and avoiding uncertainties in planning fuel cost strategy. (Author)

    Full Text Available The rapid upward shift in ethanol demand has raised concerns about ethanol’s impact on the price level and volatility of agricultural commodities. The popular press attributes much of this volatility in commodity prices to a price bubble in ethanol fuel and recent deflation. Market economics predicts not only a softening of demand to high commodity prices but also a positive supply response. This volatility in ethanol and commodity prices are investigated using cointegration, vector error corrections (VECM, and multivariate generalized autoregressive conditional heteroskedascity (MGARCH models. In terms of derived demand theory, results support ethanol and oil demands as derived demands from vehicle-fuel production. Gasoline prices directly influence the prices of ethanol and oil. However, of greater significance for the fuel versus food security issue, results support the effect of agricultural commodity prices as market signals which restore commodity markets to their equilibriums after a demand or supply event (shock. Such shocks may in the short-run increase agricultural commodity prices, but decentralized freely operating markets will mitigate the persistence of these shocks. Results indicate in recent years there are no long-run relations among fuel (ethanol, oil and gasoline prices and agricultural commodity (corn and soybean prices.

    The viability of biomass as transportation fuel depends upon the allocation of limited resources for fuel, power, and products. By focusing on mature markets, this report identifies how biomass is projected to be most economically used in the long term and the implications for greenhouse gas (GHG) emissions and petroleum use. In order to better understand competition for biomass between these markets and the potential for biofuel as a market-scale alternative to petroleum-based fuels, this report presents results of a micro-economic analysis conducted using the Biomass Allocation and Supply Equilibrium (BASE) modeling tool. The findings indicate that biofuels can outcompete biopower for feedstocks in mature markets if research and development targets are met. The BASE tool was developed for this project to analyze the impact of multiple biomass demand areas on mature energy markets. The model includes domestic supply curves for lignocellulosic biomass resources, corn for ethanol and butanol production, soybeans for biodiesel, and algae for diesel. This is one of a series of reports produced as a result of the Transportation Energy Futures (TEF) project, a Department of Energy-sponsored multi-agency project initiated to pinpoint underexplored strategies for abating GHGs and reducing petroleum dependence related to transportation.

    Alternative fuels are being considered for civilian and military uses. One of these is S-8, a replacement jet fuel synthesized using the Fischer-Tropsch process, which contains no aromatic compounds and is mainly composed of straight and branched alkanes. Metabolites of S-8 fuel in laboratory animals have not been identified. The goal of this study was to identify metabolic products from exposure to aerosolized S-8 and a designed straight-chain alkane/polyaromatic mixture (decane, undecane, dodecane, tridecane, tetradecane, pentadecane, naphthalene, and 2-methylnaphthalene) in male Fischer 344 rats. Collected blood and tissue samples were analyzed for 70 straight and branched alcohols and ketones ranging from 7 to 15 carbons. No fuel metabolites were observed in the blood, lungs, brain, and fat following S-8 exposure. Metabolites were detected in the liver, urine, and feces. Most of the metabolites were 2- and 3-position alcohols and ketones of prominent hydrocarbons with very few 1- or 4-position metabolites. Following exposure to the alkane mixture, metabolites were observed in the blood, liver, and lungs. Interestingly, heavy metabolites (3-tridecanone, 2-tridecanol, and 2-tetradecanol) were observed only in the lung tissues possibly indicating that metabolism occurred in the lungs. With the exception of these heavy metabolites, the metabolic profiles observed in this study are consistent with previous studies reporting on the metabolism of individual alkanes. Further work is needed to determine the potential metabolic interactions of parent, primary, and secondary metabolites and identify more polar metabolites. Some metabolites may have potential use as biomarkers of exposure to fuels.

    With this paper, we provide the first quantitative investigation of vertical price transmission in the biodiesel supply chain in Germany with the focus on the developments during the food crisis and the impact of subsidized US biodiesel exports. With the strong promotion of the production and use of biodiesel during the first half of the past decade, the German biodiesel market became the largest national biodiesel market worldwide. This analysis utilizes prices of rapeseed oil, soya oil, biodiesel and crude oil over a sample period covering the rapid growth of the German demand in 2002 until its decline in 2009. The effects of both the market development and different policies on price transmission are analyzed in detail. Due to the numerous changes in the market, a regime-dependent Markov-switching vector error correction model is applied. The results indicate that regimes with differing error-correction behavior govern the transmission process among the various prices. Evidence was found for a strong impact of crude oil price on biodiesel prices, and of biodiesel prices on rapeseed oil prices. However, in both cases, the price adjustment behavior is found to be regime dependent, and the regime occurrence in both market segments shows similar patterns. In relation to crude oil a weak adjustment of biodiesel prices is found to be dominating in the phase of market expansion. This changed from 2007 on when stronger error-correction is found, reflected by a stronger role of the crude oil price developments. In the relationship of biodiesel to the vegetable oils, most of the growth period was dominated by a regime characterized by weak price adjustments. From 2007 on, past own price changes and past changes in soya oil prices had a strong impact particularly on rapeseed oil prices. The biodiesel price development was less important. Reasons for this are substantial changes in the market structure. The biodiesel market developed as an insulated market; biodiesel was

    Mixed waste paper (MWP) is the second largest component of the municipal solid waste steam disposal of in Washington State. Recent state legislation has mandated source separation of recycled material including MWP. The quantity collected will soon saturate both domestic and foreign markets. An alternative market could be as a fuel in existing combustors. The use of MWP as a fuel requires environmental and economic acceptance by potential users. MWP was analyzed for heavy metal concentrations and elemental composition and found to be similar to existing solid and fossil fuels burned in existing boilers. Existing regulations, however, may classify MWP as a municipal solid waste, thus increasing the capital and administrative costs of using this fuel. The cost of processing MWP into a fluff and a pellet was determined. Three existing facilities were studied to determine the capital and operating costs for them to use MWP fuel. In all cases, the cost of processing and transporting the fuel was greater than the break-even price that could be paid by the potential users

    The U.S. Department of Energy (DOE) is focused on providing a portfolio of technology solutions to meet energy security challenges of the future. Fuel cells are a part of this portfolio of technology offerings. To help meet these challenges and supplement the understanding of the current research, Battelle has executed a five-year program that evaluated the total system costs and total ownership costs of two technologies: (1) an ~80 °C polymer electrolyte membrane fuel cell (PEMFC) technology and (2) a solid oxide fuel cell (SOFC) technology, operating with hydrogen or reformate for different applications. Previous research conducted by Battelle, and more recently by other research institutes, suggests that fuel cells can offer customers significant fuel and emission savings along with other benefits compared to incumbent alternatives. For this project, Battelle has applied a proven cost assessment approach to assist the DOE Fuel Cell Technologies Program in making decisions regarding research and development, scale-up, and deployment of fuel cell technology. The cost studies and subsequent reports provide accurate projections of current system costs and the cost impact of state-of-the-art technologies in manufacturing, increases in production volume, and changes to system design on system cost and life cycle cost for several near-term and emerging fuel cell markets. The studies also provide information on types of manufacturing processes that must be developed to commercialize fuel cells and also provide insights into the optimization needed for use of off-the-shelf components in fuel cell systems. Battelle’s analysis is intended to help DOE prioritize investments in research and development of components to reduce the costs of fuel cell systems while considering systems optimization.

  10. Market Barriers to Clean Cooking Fuels in Sub-Saharan Africa: A Review of Literature

    Energy Technology Data Exchange (ETDEWEB)

    In the developing nations of sub-Saharan Africa, providing households with modern energy services is a critical step towards development. A large majority of households in the region rely on traditional biomass fuels for cooking, which represent a significant proportion of energy used in the domestic setting. The disadvantages of these fuels are many: they are inefficient energy carriers and their heat is difficult to control; they produce dangerous emissions; and their current rate of extraction is not sustainable for forests. Transition to clean cooking fuels such as liquefied petroleum gas (LPG) or ethanol would resolve many of these issues as they do not produce dangerous particulate emissions, and are commercially viable, offering a number of socio-economic advantages over traditional options. Despite the benefits of fuel switching, clean cooking fuels are rarely used in households in sub-Saharan Africa. Their failure to attain widespread use can be attributed to a number of market barriers. One of the major issues is cost: clean cooking fuels are prohibitively expensive for many households, and the high price of compatible stoves further discourages their use. Besides the expense, many consumers are hesitant to adopt the new technology, reflecting the lack of public awareness of the relevant issues. At the same time, Africa's underdeveloped infrastructure prevents these fuels from being made available in many local marketplaces. To date, this combination of factors has largely stifled the transition to clean cooking fuels. National governments can adopt a number of strategies to address these issues. The creation of clean cooking-fuel initiatives at the national level would be an important first step, after which governments can begin to address the issues more effectively. The introduction of relevant financial instruments would help to tackle the economic barriers to clean cooking fuels, and public outreach and education could overcome socio

    Full Text Available A mixture of 1- and 2-butanol was produced using a stepwise synthesis starting with a methyl halide. The process included a carbon dioxide utilization step to produce an acetate salt which was then converted to the butanol isomers by Claisen condensation of the esterified acetate followed by hydrogenation of the resulting ethyl acetoacetate. Importantly, the CO2 utilization step uses dry, dilute carbon dioxide (12% CO2 in nitrogen similar to those found in post-combustion flue gases. The work has shown that the Grignard reagent has a slow rate of reaction with oxygen in comparison to carbon dioxide, meaning that the costly purification step usually associated with carbon capture technologies can be omitted using this direct capture-conversion technique. Butanol isomers are useful as direct drop-in replacement fuels for gasoline due to their high octane number, higher energy density, hydrophobicity, and low corrosivity in existing petrol engines. An energy analysis shows the process to be exothermic from methanol to butanol; however, energy is required to regenerate the active magnesium metal from the halide by-product. The methodology is important as it allows electrical energy, which is difficult to store using batteries over long periods of time, to be stored as a liquid fuel that fits entirely with the current liquid fuels infrastructure. This means that renewable, weather-dependent energy can be stored across seasons, for example, production in summer with consumption in winter. It also helps to avoid new fossil carbon entering the supply chain through the utilization of carbon dioxide that would otherwise be emitted. As methanol has also been shown to be commercially produced from CO2, this adds to the prospect of the general decarbonization of the transport fuels sector. Furthermore, as the conversion of CO2 to butanol requires significantly less hydrogen than CO2 to octanes, there is a potentially reduced burden on the so-called hydrogen

    The aim of the project is to provide for the Finnish bioenergy technology, machine and appliance manufactures information about forest fuel resources in the EU and international bioenergy trade mechanisms. The projects results act as an instrument for market potential assessments and provide information to the local energy producer about biomass as an energy source. The possibilities to use forest chips in CHP and heating plants will be investigated in the case studies. Total number of case studies will be 3-4, and they will mainly be located in Eastern Europe, where also large forest resources and utilisation potential are found. Case studies include three main tasks: 1) Assessment of forest fuel resources around the CHP or heating plant. 2) Forest fuel procurement cost study and 3) Study on the economics forest fuel based energy production. The project will be carried out as cooperation between Finnish research institutes and companies, and local actors. First case study was carried out at Poland. (orig.)

    The European Union develops common EU policy and strategy on biofuels and sustainable bio-economy through several documents. The encouragement of biofuel's consumption is therefore the obligation of each EU member state. The situation in Slovenian fuel market is presented and compared with other EU countries in the frame of prescribed values from EU directives. Diesel is the most common fuel for transportation needs in Slovenia. The study was therefore performed on diesel. The sampling net was determined in accordance with the fuel consumption statistics of the country. 75 Sampling points were located on different types of roads. The quantity of bio-component in diesel samples was determined by direct LSC method through measurement of C-14 content. The measured values were in the range from 0 up to nearly 6 mass percentage of bio-component in fuel. The method has proved to be appropriate, suitable and effective for studies on the real fuel market. Copyright © 2014 Elsevier Ltd. All rights reserved.

Moreover, it is found that the widespread diffusion of fuel-cell cars in China will first and only take place after 2025. Main conditions are firstly: the removal of technological and economic obstacles, the appearance of an initial niche market and the self-enforcement of diffusion (with consensus among the important actors, driven by the technological development. Secondly: either high price of fossil fuels (energy resource scarcity is required or (very strict environmental regulations by the Chinese government -i.e. a breakthrough of the present policy trend.

    Full Text Available Indirect land use change, an agricultural market leakage, has been a major controversy over the Environmental Protection Agency’s (EPA requirement for corn-ethanol to reduce greenhouse gas (GHG emissions by 20 percent relative to gasoline it is assumed to replace. This paper shows that corn-ethanol policies generate far greater carbon leakage in the fuel market itself. Hence, corn-ethanol does not meet EPA’s threshold, regardless of ethanol policy and whether one includes emissions from land use change.

    The Dynamic Resource Exchange (DRE) gives agency to consumer facilities to determine the preference of any particular trade that is offered by suppliers to satisfy its requests. This provides a natural balance of power in the relationship between consumers and suppliers. However, in situations in which suppliers have flexibility surrounding the way that they respond to individual requests, they have no mechanism to assess how different bids will be received by the consumer. Theoretically, a supplier can offer multiple bids to respond to a given request in an attempt to “cover their bases”, but this introduces more arcs into the underlying network flow problem, increasing the cost to solve the problem. In the extreme, when a supplier can continuously vary the characteristics of the bid, this can represent a large number of additional arcs and have real performance consequences. To remedy this inefficiency in the implementation of the market-level optimization, the definition of a request has been extended to include a function that can be used by the supplier to query the preference that would be assigned by a consumer for a potential bid. The supplier is then free to implement arbitrarily complex algorithms to revise/optimize its bid based on responses to this function. A supplier can chose to not invoke the function at all, mimicking the original DRE behavior, can use it to select among a small set of discrete choices, or can implement an internal algorithm to seek an optimum bid on a continuous parameter space. This capability was demonstrated with a storage facility that preferred material with a specific decay heat that was as close as possible to the maximum allowable decay heat, while requiring the specific decay heat to fall between a minimum and maximum level. This archetype was used to fill multiple storage roles in a simulation that also included a standard recipe reactor: wet storage with no maximum allowable specific decay heat, dry storage with a

    Low ethanol prices relative to the price of gasoline blendstock, and tax credits, have resulted in discretionary blending at wholesale terminals of ethanol into fuel supplies above required levels-a practice known as ethanol splashing in industry parlance. No one knows precisely where or in what volume ethanol is being blended with gasoline and this has important implications for motor fuels markets: Because refiners cannot perfectly predict where ethanol will be blended with finished gasoline by wholesalers, they cannot know when to produce and where to ship a blendstock that when mixed with ethanol at 10% would create the most economically efficient finished motor gasoline that meets engine standards and has comparable evaporative emissions as conventional gasoline without ethanol blending. In contrast to previous empirical analyses of biofuels that have relied on highly aggregated data, our analysis is disaggregated to the level of individual wholesale fuel terminals or racks (of which there are about 350 in the US). We incorporate the price of ethanol as well as the blendstock price to model the wholesaler's decision of whether or not to blend additional ethanol into gasoline at any particular wholesale city-terminal. The empirical analysis illustrates how ethanol and gasoline prices affect ethanol usage, controlling for fuel specifications, blend attributes, and city-terminal-specific effects that, among other things, control for differential costs of delivering ethanol from bio-refinery to wholesale rack. - Research Highlights: > Low ethanol prices and tax credits have resulted in discretionary blending of ethanol into fuel supplies above required levels. > This has important implications for motor fuels markets and vehicular emissions. > Our analysis incorporates the price of ethanol as well as the blendstock price to model the wholesaler's decision of whether or not to blend additional ethanol into gasoline at any particular wholesale city

  3. Why has the introduction of natural gas vehicles failed in Germany?—Lessons on the role of market failure in markets for alternative fuel vehicles

    2015-01-01

    Despite private investments exceeding two billion Euros and tax incentives of more than 500 million Euros, the market share of natural gas vehicles (NGVs) in Germany has lagged far behind expectations and behind market developments in other countries. With total cost of ownership being on average lower for NGVs than for gasoline and diesel vehicles this raises the question of the existence of market failure in the German NGV-market. We use a case study approach where we combine quantitative data with insights from a multi-industry expert panel and in-depth interviews with experts from industry, government and civil society in order to examine whether and how different types of market failure contribute to the status quo in the German market for NGVs. We conclude that coordination failure in complementary markets, an artificially created monopoly of service stations at motorways, imperfect information, bounded consumer rationality, and principle-agent-problems are the most prominent market failures inhibiting the development of a functioning market for NGVs. Our results are instructive for the design of effective public policies and investor strategies aiming to create markets for alternative fuel vehicles. - Highlights: • We analyze market failure in the German market for natural gas vehicles. • Coordination failure is the most important reason for market failure to arise. • Minor factors: regulatory deficits, imperfect information, bounded rationality. • Policies encompass stabilizing expectations and supporting actor coordination. • Our results are instructive for policies and investor strategies in AFV-markets

    Full Text Available This paper deals with analysis of current problems in the motor fuel market. It analyzes bottlenecks in setting the legislative changes in value added tax, excise tax and the legislation concerning fuels. The biggest problem is tax evasions that favor one group of business entities at the expense of another, and also cause that the state loses revenues mainly from indirect taxes. Therefore, attention is directed to quality control of fuels as a means of consumer protection and prevention of tax evasion and ways to combat tax evasion in import, distribution and storage of mineral oils. The examples are the most common errors found in fraudulent companies. Based on the data collected the possible ultimate evasion was estimated. Therefore, I propose that value added tax law should be amended and some other measures to improve supervision by public authorities like tax authorities and customs administration offices should be taken.

    Several initiatives are currently being developed in the Netherlands for the production of fuel pellets from waste and biomass. This report presents an overview of the current producers and (potential) users of these pellets in the Netherlands. It also outlines the Dutch and European policies and legislations concerned. Furthermore, important barriers to market development of fuel pellets are defined and future expectations are summarized. The study covers fuel pellets made from different feedstock, varying from clean biomass to waste with traces of contaminants. In each project, pellets are produced that are unique as to their product specifications, as they are usually designed for a single application. It is therefore impossible to generalize characteristics and end use. 27 refs

    The use of biodiesel is increasing as an attractive fuel due to the depleting fossil fuel resources and environmental degradation. This paper presents results of an investigation on the potentials of biodiesel as an alternative fuel and main substitute of diesel oil, comparing the CO 2 emissions of the main fuels in the Brazilian market with those of biodiesel, in pure form or blended in different proportions with diesel oil (2%, 5%, and 20%, called B2, B5, and B20, respectively). The results of the study are shown in ton CO 2 per m 3 and ton CO 2 per year of fuel. The fuels were analyzed considering their chemical composition, stoichiometric combustion parameters and mean consumption for a single vehicle. The fuels studied were: gasoline, diesel oil, anhydrous ethyl alcohol (anhydrous ethanol), and biodiesel from used frying oil and from soybean oil. For the case of biodiesel, its complete life cycle and the closed carbon cycle (photosynthesis) were considered. With data provided by the Brazilian Association of Automotive Vehicle Manufacturers (ANFAVEA) for the number of vehicles produced in Brazil, the emissions of CO 2 for the national fleet in 2007 were obtained per type of fuel. With data provided by the Brazilian Department of Transit (DENATRAN) concerning the number of diesel vehicles in the last five years in Brazil, the total CO 2 emissions and the percentage that they would decrease in the case of use of pure biodiesel, B100, or several mixtures, B2, B5 and B20, were calculated. Estimates of CO 2 emissions for a future scenario considering the mixtures B5 and B20 are also included in this article. (author)

    2016-01-01

    Long-run dynamics of electricity prices are expected to reflect fuel price developments, since fuels generally account for a large share in the cost of generation. As an integrated European market for electricity develops, wholesale electricity prices should be converging as a result of market coupling and increased interconnectivity. Electricity mixes are also changing, spurred by a drive to significantly increase the share of renewables. Consequently, the electricity wholesale price dynamics are evolving, and the fuel–electricity price nexus that has been described in the literature is likely to reflect this evolution. This study investigates associations between spot prices from the British, French and Nordpool markets with those in connected electricity markets and fuel input prices, from December 2005 to October 2013. In order to assess the time-varying dynamics of electricity spot price series, localized autocorrelation functions are used. Electricity spot prices in the three markets are found to have stationary and non-stationary periods. When a trend in spot prices is observed, it is likely to reflect the trend in fuel prices. Cointegration analysis is then used to assess co-movement between electricity spot prices and fuel inputs to generation. The results show that British electricity spot prices are associated with fuel prices and not with price developments in connected markets, while the opposite is observed in the French and Nordpool day-ahead markets. - Highlights: • Electricity market integration policies may have altered EU spot electricity prices. • LACF is used to assess the changing nature of electricity spot prices. • EU electricity spot prices show both stationary and non-stationary periods. • Carbon and fuel prices have greater impact on British spot prices. • In continental Europe, electricity prices have decoupled from fuel prices.

    This report contains results concerning inspection of copper canisters for spent nuclear fuel by means of ultrasound obtained at Signals and Systems, Uppsala University in year 2001/2002. The first chapter presents results of an investigation of a new method for synthetic aperture imaging. The new method presented here takes the form of a 2D filter based on minimum mean squared error (MMSE) criteria. The filter, which varies with the target position in two dimensions includes information about spatial impulse response (SIR) of the imaging system. Spatial resolution of the MMSE method is investigated and compared experimentally to that of the classical SAFT and phased array imaging. It is shown that the resolution of the MMSE algorithm, evaluated for imaging immersed copper specimen is superior to that observed for the two above-mentioned methods. Extended experimental and theoretical research concerning the potential of nonlinear waves and material harmonic imaging is presented in the second chapter. An experimental work is presented that was conducted using the RITEC RAM-5000 ultrasonic system capable of providing a high power tone-burst output. A new method for simulation of nonlinear acoustic waves that is a combination of the angular spectrum approach and the Burger's equation is also presented. This method was used for simulating nonlinear elastic waves radiated by the annular transducer that was used in the experiments.

The objectives of the project were the following: 1) To give a clear outlook on current and future biomass fuel market trends. 2) To give feedback on the suitability of CEN 335 biofuel standard for trading of solid biofuels. 3) To provide well-analysed estimation on techno-economic potential of the biomass fuel volumes until 2010 based on the existing studies and experts opinions. Regarding the forest biomass sector, co-operation will be done with forest industry stakeholders to find proper balance between forest industry raw material and bioenergy usage. 4) To enhance biomass fuel trade and technology transfer by networking among different actors. 5) To analyse, select and describe the most suitable trading and business models for small- and largescale biofuel supply chains for heat and power production by taking into account the environmental aspects and sustainability. 6) To enhance biomass usage by the means of co-operation and information dissemination among different market actors in the fuel-utilisation chain. Target groups were biomass fuel traders and users, fuel producers and suppliers of different scales, policy makers in both current and new member states. Key associations, i.e. AEBIOM and CEPI, were participating in the project and disseminating information to various groups. The project has been structured in 5 workpackages. Project was carried out by 16 partners, which are the key national bioenergy organisations in the European countries and have a long co-operation relationship in previous bioenergy networks. The project has published summary reports and national report of each WP and this report is

  13. The global nuclear fuel market - supply and demand 1995-2015

    The findings and main conclusions of the 1996 supply and demand report of the Uranium Institute are summarised. The previous report was published in June 1994. In 1994 and 1995, world uranium production remained at a relatively depressed level, accounting for just over half reactor requirements only. Since mid 1995, however, some increase in production has occurred alongside rises in uranium spot market prices. This may indicate that supply is becoming tighter and indicate the end of the perception that supply availability is unlimited. Answers are attempted to the questions about the future which arise from this development. Nuclear power is first set in the context of the market for energy and for electricity in particular. The report then identifies key issues for the longer term future for nuclear power and considers various aspects of nuclear fuel supply and demand over the next 20 years. Three demand scenarios are explored. Even in the lower requirements case, the overall conclusion is that supply will only meet demand from 2002 onwards when all the projected new mine capacity is in place. Adequate supply is heavily dependent on other supply sources in the higher case scenarios. The market will need the entry of blended down high enriched uranium from dismantled weapons and an increased contribution from the reprocessing of spent fuel. Additional primary production is only likely if financial incentives are available and the regulatory framework permits. Finally, there is the possibility of re-enriching depleted uranium.

  14. North America markets for alcohol and alcohol-derived motor fuels and need for tax incentives

    1991-01-01

    The U.S. fuel alcohol and ether industry has grown from its infancy in 1979 to approximately 2.9 billion gallons of production capacity in 1991. With the emphasis on clean air, the uncertainties in the Middle East, and fluctuating oil prices, IRI believes the demand for alcohol-derived motor fuels is poised to begin a second phase of expansion. Historically, the two primary alcohol-derived motor fuels sold in the U.S. have been methyl tertiary butyl ether (MTBE) and ethanol. There is also a limited but growing use of methanol as 85% blendstock for gasoline. Since 1978, fuel ethanol has provided the U.S. petroleum industry with an additional source of supply, octane, and profit. Its price was based on the price of wholesale gasoline plus available federal and state tax incentives. These incentives allowed ethanol, with production costs of $1.00 to $1.25 per gallon, to compete with gasoline at prices of 40 to 65 per gallon. Without the federal and state tax incentives, it would not be economically feasible to sell or manufacture fuel ethanol. On the other hand, the largest consumption of methanol has been as a feedstock for the production of MTBE, the world's fastest growing chemical over the past seven years. MTBE prices are based on the cost of raising the octane level of gasoline, and this commodity does not receive subsidies. Beginning in 1992, IRI predicts the price relationship between ethanol, MTBE, and gasoline will change as U.S. refiners and marketers are required to include oxygenated fuels (alcohol-derived) in their gasoline. In total, over 60 billion gallons of gasoline will need to be reformulated by the year 2000. The increased demand for oxygen will result in a 2.5-billion gallon deficit of MTBE and 1.2-billion gallon deficit of ethanol by the year 2000. 2 tabs

  15. Long-Term Hydrocarbon Trade Options for the Maghreb Region and Europe—Renewable Energy Based Synthetic Fuels for a Net Zero Emissions World

    Full Text Available Concerns about climate change and increasing emission costs are drivers for new sources of fuels for Europe. Sustainable hydrocarbons can be produced synthetically by power-to-gas (PtG and power-to-liquids (PtL facilities, for sectors with low direct electrification such as aviation, heavy transportation and chemical industry. Hybrid PV–Wind power plants can harvest high solar and wind potentials of the Maghreb region to power these systems. This paper calculates the cost of these fuels for Europe, and presents a respective business case for the Maghreb region. Calculations are hourly resolved to find the least cost combination of technologies in a 0.45° × 0.45° spatial resolution. Results show that, for 7% weighted average cost of capital (WACC, renewable energy based synthetic natural gas (RE-SNG and RE-diesel can be produced in 2030 for a minimum cost of 76 €/MWhHHV (0.78 €/m3SNG and 88 €/MWhHHV (0.85 €/L, respectively. While in 2040, these production costs can drop to 66 €/MWhHHV (0.68 €/m3SNG and 83 €/MWhHHV (0.80 €/L, respectively. Considering access to a WACC of 5% in a de-risking project, oxygen sales and CO2 emissions costs, RE-diesel can reach fuel-parity at crude oil prices of 101 and 83 USD/bbl in 2030 and 2040, respectively. Thus, RE-synthetic fuels could be produced to answer fuel demand and remove environmental concerns in Europe at an affordable cost.

    Hydrogen fuel cells can potentially reduce greenhouse gas emissions and the United States dependence on foreign oil, but issues with hydrogen storage are impeding their widespread use. To help overcome these challenges, this study analyzes opportunities for their near-term deployment in five categories of non-motive equipment: portable power, construction equipment, airport ground support equipment, telecom backup power, and man-portable power and personal electronics. To this end, researchers engaged end users, equipment manufacturers, and technical experts via workshops, interviews, and electronic means, and then compiled these data into meaningful and realistic requirements for hydrogen storage in specific target applications. In addition to developing these requirements, end-user benefits (e.g., low noise and emissions, high efficiency, potentially lower maintenance costs) and concerns (e.g., capital cost, hydrogen availability) of hydrogen fuel cells in these applications were identified. Market data show potential deployments vary with application from hundreds to hundreds of thousands of units.

    Monte Carlo simulations of gas, coal and nuclear plant investment returns are used as inputs of a Mean-Variance Portfolio optimization to identify optimal base load generation portfolios for large electricity generators in liberalized electricity markets. We study the impact of fuel, electricity, and CO 2 price risks and their degree of correlation on optimal plant portfolios. High degrees of correlation between gas and electricity prices - as observed in most European markets - reduce gas plant risks and make portfolios dominated by gas plant more attractive. Long-term power purchase contracts and/or a lower cost of capital can rebalance optimal portfolios towards more diversified portfolios with larger shares of nuclear and coal plants

  20. The integration of major fuel source markets in China. Evidence from panel cointegration tests

    2010-01-01

    The paper tests for energy price co-movement in China over the 'new regime' as part of a strategy to test for the existence of a national energy market. Panel cointegration test statistics suggest that not all energy commodities are spatially homogenous in prices and the processes of energy price cointegration are different over time and over groups of fuels. The statistics demonstrate China's gradual, spatially partial and idiosyncratic energy reform process. Coal and electricity price series have co-moved since 2003, while the national panel cointegration test statistics suggest that gasoline and diesel price series have co-moved since 1997. Regional panel tests also show that there are apparently differences in the emergence of energy price co-movement. This suggests that regional energy markets have emerged in China. One of the important lessons of the research is that an energy market has, to some extent, already emerged in China and, as a consequence, energy prices are much less distorted than previously. If correct, this fact is of major global significance both in terms of future environmental effects and future trade and investment negotiations as China is seen internationally as a 'market driven economy'.

    Direct hydrogen polymer electrolyte membrane fuel cells (H-PEMFCs) offer several near-term opportunities including backup power applications in state and local agencies of emergency response; forklifts in high throughput distribution centers; and, airport ground support equipment. This paper presented an analysis of the market requirements for introducing H-PEMFCs successfully, as well as an analysis of the lifecycle costs of H-PEMFCs and competing alternatives in three near-term markets. It also used three scenarios as examples of the potential for market penetration of H-PEMFCs. For each of the three potential opportunities, the paper presented the market requirements, a lifecycle cost analysis, and net present value of the lifecycle costs. A sensitivity analysis of the net present value of the lifecycle costs and of the average annual cost of owning and operating each of the H-PEMFC opportunities was also conducted. It was concluded that H-PEMFC-powered pallet trucks in high-productivity environments represented a promising early opportunity. However, the value of H-PEMFC-powered forklifts compared to existing alternatives was reduced for applications with lower hours of operation and declining labor rates. In addition, H-PEMFC-powered baggage tractors in airports were more expensive than battery-powered baggage tractors on a lifecycle cost basis. 9 tabs., 4 figs

    The objective of the present work is to validate the hydrogen energy roadmap of Japan by analyzing the market penetration of fuel cell vehicles (FCVs) and the effects of a carbon tax using an energy system model of Japan based on MARKAL. The results of the analysis show that a hydrogen FCV would not be cost competitive until 2050 without a more severe carbon tax than the government's planned 2400 JPY/t-C carbon tax. However, as the carbon tax rate increases, instead of conventional vehicles including the gasoline hybrid electric vehicle, hydrogen FCVs gain market penetration earlier and more. By assuming a more severe carbon tax rate, such as 10 000 JPY/t-C, the market share of hydrogen FCVs approaches the governmental goal. This suggests that cheaper vehicle cost and hydrogen cost than those targeted in the roadmap should be attained or subsidies to hydrogen FCV and hydrogen refueling station will be necessary for achieving the goal of earlier market penetration.

    In the last 10 years, the power generation market has seen radical changes. The coming years will see yet more change. Although the pace of change may be uneven across Europe, it is clear that the old reference points for the power generation market are no longer valid. Along with other market players, Shell has re-evaluated the role it wishes to play in the power generation market. Although it has long operated large generation capacity on its own sites, Shell's role has been that of a fuel supplier to monopoly power generation and distribution organizations, which were largely state controlled . Privatization and liberalization have been followed by changing market structures tending to push risk towards the producer. This evolution presents challenges for the normal IPP structure, where market risk is transferred and offers an opportunity for the active participation of the fuel supplier in meeting these challenges. In 1996, Shell decided to embrace the changes in power generation market. Already, significant steps have been taken in markets in Asia, Latin America and in Europe. The differing requirements of each of these markets means there are no standard solutions and requires Shell to devise flexible frameworks which meet the customer's needs. Shell is bringing its significant strengths to the power generation market and looks forward to participating on a world wide scale in the industry at this exciting phase in its development

    The research focus on the European fuel market prices referring to the Rotterdam and Genoa spot markets as well the German, Italian and French domestic markets. The thesis try to explain the impact of the London IPE future market on spot prices too. The mainstream research has demonstrated that co-integration seems to be the best theoretical approach to investigate the long run equilibrium relations. A particular attention will be devoted to the structural change in the econometric modelling on these equilibriums. A deep analysis of the main European petroleum products markets permit a better model specification concerning each of these markets. Further, we will test if any evidence of relations between spot and domestic prices could be confirmed. Finally, alternative scenarios will be depicted to forecast prices in the petroleum products markets. The objective is to observe the model reaction to changes crude oil prices. (author)

  6. Three Essays on Renewable Energy Policy and its Effects on Fossil Fuel Generation in Electricity Markets

    Science.gov (United States)

    Bowen, Eric

    In this dissertation, I investigate the effectiveness of renewable policies and consider their impact on electricity markets. The common thread of this research is to understand how renewable policy incentivizes renewable generation and how the increasing share of generation from renewables affects generation from fossil fuels. This type of research is crucial for understanding whether policies to promote renewables are meeting their stated goals and what the unintended effects might be. To this end, I use econometric methods to examine how electricity markets are responding to an influx of renewable energy. My dissertation is composed of three interrelated essays. In Chapter 1, I employ recent scholarship in spatial econometrics to assess the spatial dependence of Renewable Portfolio Standards (RPS), a prominent state-based renewable incentive. In Chapter 2, I explore the impact of the rapid rise in renewable generation on short-run generation from fossil fuels. And in Chapter 3, I assess the impact of renewable penetration on coal plant retirement decisions.

    There exists already a market of bio-automotive fuels i.e. bioethanol and biodiesel produced from food crops in many countries. From the viewpoint of economics, environment, land use, water use and chemical fertilizer use, however, there is a strong preference for the use of woody biomass and various forest/agricultural residues as the feedstock. Thus, the production of 2nd generation of bio-automotive fuels i.e. synthetic fuels such as methanol, ethanol, DME, FT-diesel, SNG and hydrogen through biomass gasification seems promising. The technology of producing synthetic fuels is well established based on fossil fuels. For biomass, however, it is fairly new and the technology is under development. Starting from the present market of the 1st generation bio-automotive fuels, this paper is trying to review the technology development of the 2nd generation bio-automotive fuels from syngas platform. The production of syngas is emphasized which suggests appropriate gasifier design for a high quality syngas production. A number of bio-automotive fuel demonstration plant will be presented, which gives the state of the art in the development of BTS (biomass to synthetic fuels) technologies. It can be concluded that the 2nd generation bio-automotive fuels are on the way to a breakthrough in the transport markets of industrial countries especially for those countries with a strong forest industry.

    The Nigerian government proposed the use of compressed natural gas (CNG) as an automotive fuel in 1997 as part of the initiatives to harness natural gas (NG) resources but progress has been slow. This paper examines the natural gas vehicle (NGV) implementation approaches and outcomes in seven countries with diverse experiences in order to gain an understanding of the barriers to the NGV market development in Nigeria. The analysis employs hermeneutic principles to secondary data derived from academic literature, published reports from a variety of international agencies, grey literature, and text from online sources and identifies eight success factors for NGV market development namely: strategic intent, legal backing, learning and adaptation, assignment of responsibilities, financial incentives, NG pricing, consumer confidence, and NG infrastructure. The paper concludes that the principal impediment to NGV market development in Nigeria is the uncoordinated implementation approach and that greater government involvement is required in setting strategic goals, developing the legal and regulatory frameworks, setting of clear standards for vehicles and refuelling stations as well as assigning responsibilities to specific agencies. Short-term low cost policy interventions identified include widening the existing NG and gasoline price gap and offering limited support for refuelling and retrofitting facilities. - Highlights: • We examined the NGV policies and implementation strategies in selected countries. • The use of legislative mandates help deepen NGV penetration. • Aligning stakeholder interest is critical to NGV adoption. • Making national interest a priority ahead of regional infrastructure is a critical success factor. • Government support drives participation

    Full Text Available The paper deals with value added tax evasions on the fuel market in the Czech Republic. This commodity is used in carousel fraud. In the chains of taxpayers there are missing traders who fail to meet their tax obligations. Their business strategy is based on quick sales at unusually low prices which do not allow honest parties to compete. Tax administrators should focus on unusual prices which constitute a higher probability of tax evasions. This paper aims to verify whether or not there are ways to evade the measure, focusing specifically on applying methods which could help achieve lower sales prices while avoiding the possibility to require unpaid tax from the recipients of taxable supply. The weaknesses thus found are described and demonstrated in more detail in the paper. During a research some ways were found which could be used for avoiding this specific measure. Methods of Cash Back and Free Shipping were identified and described.

    Decarbonising transport is proving to be one of today's major challenges for the global automotive industry due to many factors such as the increase in greenhouse gas and particulate emissions affecting not only the climate but also humans, the increase in pollution, rapid oil depletion, issues with energy security and dependency from foreign sources and population growth. For more than a century, our society has been dependent upon oil, and major breakthroughs in low- and ultra-low carbon technologies and vehicles are urgently required. This review paper highlights the current status of hybrid, battery and fuel cell electric vehicles from an electrochemical and market point of view. The review paper also discusses the advantages and disadvantages of using each technology in the automotive industry and the impact of these technologies on consumers.

    2018-04-01

    This research was based on the investigation of a major principle, regarding the effects of NaCl and KH 2 PO 4 concentrations on struvite recovery, with electricity production using magnesium-air fuel cell electrocoagulation, in accordance with the concentration of phosphorous and chloride. The weight ratio of N:P in the synthetic wastewater was in the range of 1.2-21. The concentration of NH 4 Cl was fixed at 0.277 M (approximately 3888 ppm as NH 3 -N and 5000 ppm as NH 4 ), while PO 4 -P was in the range of 0.006-0.1 M. In addition, the concentrations of NaCl as electrolyte were 0, 0.01, and 0.1 M. Phosphate removal increased linearly with the Mg:P ratio, up to approximately 1.1 mol mol -1 , irrespective of the initial concentrations of phosphate and NaCl. The one-to-one reaction as mole ratio between phosphate and the dissolved Mg ions resulted in phosphate removal, with the production of a one-to-one magnesium/phosphate mineral, such as struvite. The average removal rate of phosphorous in experiments without a dose of NaCl was 4.19 mg P cm -2 h -1 , which was lower than the relative values of 5.35 and 4.77 mg P cm -2 h -1 , in experiments with 0.01 and 0.1 M NaCl. The dissolution rate of Mg with electro-oxidation determined the rate of phosphorous removal with struvite recovery. The average removal rates of phosphorous with dose concentrations of 0.006, 0.01 and 0.02 M KH 2 PO 4 were 4.02, 5.54, 6.9 mg P cm -2 h -1 , respectively, which increased with the increase in KH 2 PO 4 dose. However, in experiments with a dose of 0.05 and 0.1 M KH 2 PO 4, the average removal rates of phosphorous decreased to 4.84 and 2.51, respectively. The maximum power densities in the electrolyte mixture of 0.05 M KH 2 PO 4 /0.277 M NH 4 Cl, 0.01 M NaCl/0.05 M KH 2 PO 4 /0.277 M NH 4 Cl, and 0.1 NaCl/0.05 KH 2 PO 4 /0.277 M NH 4 Cl were 25.1, 26.4, and 33.2 W/m 2 , respectively. The increase in the NaCl dose concentration resulted in an

    Full Text Available The sustainable energy consumption in northeast Asia has a huge impact on regional stability and economic growth, which gives price volatility research in the energy market both theoretical value and practical application. We select China’s fuel oil futures market as a research subject and use recurrence interval analysis to investigate the price volatility pattern in different thresholds. We utilize the stretched exponential function to fit the pattern of the recurrence intervals of price fluctuations and find that the probability density functions of the recurrence intervals in different thresholds do not show the scaling behavior. Then the conditional probability density function and detrended fluctuation analysis prove that there is short-term and long-term correlation. Last, we use a hazard function to introduce the recurrence intervals into the (value at risk VaR calculation and establish a functional relationship between the mean recurrence interval and the threshold. Following this result, we also shed light on policy discussion for hedgers and government.

    The purpose of the project is to select and validate technology concepts for the establishment of a Danish production of green synthetic fuels primarily for fuel cells. The feasibility of the selected concepts is assessed trough a techno-economical calculation, which includes mass and energy balances and economics including CAPEX and OPEX assessments. It is envisioned by the project partners that a production of green synthetic fuels, such as methanol, can 1) bring stability to a future electricity grid with a high share of renewable energy, 2) replace fossil fuels in the transport sector, and 3) boost Danish green technology export. In the project, two technology concepts were derived through carefully considerations and plenum discussions by the project group members: Concept 1): Methanol/DME Synthesis based on Electrolysis assisted Gasification of Wood. Concept 2): Methanol/DME synthesis based on biogas temporarily stored in the natural gas network. Concept 1) is clearly the most favored by the project group and is therefore analyzed for its techno-economic feasibility. Using mass and energy balances the technical perspectives of the concept were investigated, along with an economic breakdown of the CAPEX and OPEX cost of the methanol production plant. The plant was technically compared to a traditional methanol production plant using gasified biomass. The project group has decided to focus on large scale plants, as the scale economics favor large scale plants. Therefore, the dimensioning input of the concept 1) plant is 1000 tons wood per day. This is truly a large scale gasification plant; however, in a methanol synthesis context the plant is not particularly large. The SOEC electrolyzer unit is dimensioned by the need of hydrogen to balance the stoichiometric ratio of the methanol synthesis reaction, which will result in 141 MW installed SOEC. The resulting methanol output is 1,050 tons methanol per day. In comparison to a traditional methanol synthesis plant

    Sprint is one of the telecommunications industry leaders in the deployment of hydrogen fuel cell (HFC) systems to provide backup power for their mission critical wireless network facilities. With several hundred fuel cells commissioned in California, states in the gulf coast region, and along the upper eastern seaboard. A strong incentive for advancing the integration of fuel cells into the Sprint network came through the award of a Department of Energy (DOE) grant focused on Market Transformation activities for project (EE0000486). This grant was funded by the 2009 American Recovery and Reinvestment Act (ARRA). The funding provided by DOE ($7.295M) was allocated to support the installation of 260 new HFC systems, equipped with an on-site refillable Medium Pressure Hydrogen Storage Solution (MPHSS), as well as for the conversion of 21 low pressure hydrogen systems to the MPHSS, in hopes of reducing barriers to market acceptance.

  18. The making of a market. Supply- and demand-side perspectives on institutional innovation in Sweden's wood fuel use

    2001-01-01

    This thesis documents and analyses the rapidly increasing wood fuel use in Sweden in five separate studies of prominent actors in the making of the wood fuel market. These studies report government policy, forest owners' incentives, and district heating companies' experiences. The development of wood fuel use is examined as a story of technological and institutional change initially prompted by government policy. The change has involved dedicated action among all of the actors, with the Swedish government initiating new policies, legislation, and information activities, with district heating companies investing in new technology and trading, and with forest owners making new decisions on forest management practices. Institutional change in the wood fuel sector, in other words, is the result of innovation on the part of the actors involved. The papers included in the study identify and analyse concerns of the actors involved in making the wood fuel market. Within the district heating sector, transaction costs, as measured by problems to trade perceived by managements, have decreased with learning. Transformation costs, due to technical problems, are not perceived to have followed this trend. Technical investments in heat production have a long technical life time and demand large investment costs. This in turn means long planning and decision periods. Investments are made for a number of company-specific reasons, perhaps most importantly simply to increase heat and/or electricity generation capacity. Policy instruments may tip a decision in favor of wood fuels, but they could not be the single parameter determining company investments. Two kinds of forest owners selling wood fuels were identified, a forest manager type who acts more on his/her own initiative, and another kind, who relies more on the advice of the traditional timber buyer. Forest owners selling wood fuels contemplating whether to sell wood fuels or not are strongly influenced by soil fertility

    This article discusses the delays being encountered in the introduction of fuel cells into various application areas and the work that is still to be done before this technology breaks through into the market. The situation in the space-heating / decentralised power generation segment is examined, where a large amount of work still has to be done before such fuel cell units attain the status of everyday domestic appliances. The situation in the combined heat and power (CHP) segment in Germany is discussed, where local utilities are working together with fuel cell manufacturers within the framework of field trails of domestic fuel cell appliances. The setting-up of 'virtual power stations' - a network of remote-controlled distributed fuel-cell CHP units - is discussed and the chances for the success of applications for miniaturised fuel cells in consumer goods such as cameras and mobile telephones is examined. The situation in the automobile industry, where the introduction of fuel cell applications in vehicles is also suffering delays, is looked at. Also, the production of hydrogen for use in the fuel cells is examined

    The potential of GTL diesel fuel for further improving engine performance and reducing exhaust emissions beyond euro 4 was investigated in a Mercedes-Benz E320 CDI passenger car. Starting with the outlook on the production and properties of GTL fuel against the anticipated future diesel demand, the paper addresses the impacts of GTL diesel fuel on heavy-duty and light-duty engines. Based on preceding work on un-adapted engines, published in an earlier paper in 2004 at the 25{sup th} International Vienna Motor Symposium, the hardware configuration and software calibration of the E320 engine were now modified to better utilize the advantageous properties of the Sasol Chevron GTL diesel fuel. In order to keep engine changes at a minimum, hardware modifications were limited to lowering the compression ratio and optimizing the injection equipment. These hardware modifications required the adaptation of the engine software calibration, such as injection system parameters, boost pressure adjustment, and EGR rates. It has been shown that, by detailed bench work and chassis dynamometer testing, the vehicle, which is equipped with a DPF and has a euro 4 calibration in its original form, can comply with the very stringent nitrogen oxides emission limits of 0.08 g/km (NEDC) when moderately modified and operated on GTL diesel fuel. This was achieved without any active nitrogen oxides exhaust gas aftertreatment. This establishes a very promising outlook for a cost-efficient means for reducing exhaust emissions, and again highlights the benefits that may be obtained with cleaner fuels (GTL diesel fuel is free of sulfur and aromatics and has a cetane number > 70). The paper presents details of the fuel, the engine modifications and the test results obtained so far. (orig.)

    Exposure to fuels continues to be a concern in both military and general populations. The aim of this study was to examine effects of in vivo rat repeated exposures to different types of jet fuel utilizing microelectrode arrays for comparative electrophysiological (EP) measurements in hippocampal slices. Animals were exposed to increasing concentrations of four jet fuels, Jet Propellant (JP)-8, Jet A, JP-5, or synthetic Fischer Tropsch (FT) fuel via whole-body inhalation for 20 d (6 hr/d, 5 d/week for 28 d) and synaptic transmission as well as behavioral performance were assessed. Our behavioral studies indicated no significant changes in behavioral performance in animals exposed to JP-8, Jet A, or JP-5. A significant deviation in learning pattern during the Morris water maze task was observed in rats exposed to the highest concentration of FT (2000 mg/m 3 ). There were also significant differences in the EP profile of hippocampal neurons from animals exposed to JP-8, Jet A, JP-5, or FT compared to control air. However, these differences were not consistent across fuels or dose dependent. As expected, patterns of EP alterations in brain slices from JP-8 and Jet A exposures were more similar compared to those from JP-5 and FT. Further longitudinal investigations are needed to determine if these EP effects are transient or persistent. Such studies may dictate if and how one may use EP measurements to indicate potential susceptibility to neurological impairments, particularly those that result from inhalation exposure to chemicals or mixtures.

    Although natural gas as a car fuel is a more environmentally clean alternative to gasoline or diesel and gas is considerable cheaper and much safer than other fuels, costumers are still suspicious of alternative fuels and vehicles. The main reasons are a lack of awareness and information on the consumer side, as well as a low information and acceptance level among car dealers and service stations. Therefore the MADEGASCAR project directly addresses major barriers by specific actions. The project MADEGASCAR (Market development for gas driven cars including supply and distribution of biogas), co-funded by the Intelligent Energy Europe programme of the European commission, aims at developing the market for natural gas vehicles by addressing target groups at the demand side (private car owners, fleet managers) as well as strengthening the supply and distribution infrastructure for Compressed Natural Gas (CNG) and Natural Gas Vehicles (NGVs) municipalities, car dealers, owners of fuel stations, natural gas and biogas suppliers) in 10 participating partner countries. The Unique Selling Point of the MADEGASCAR project is deployment in several regional areas instead of sole basic research. Country specific action plans, which are developed and implemented in the project, will have direct impact on regional markets but also affect car manufacturers and national regulations, resulting in long term changes. The main ambition of the MADEGASCAR project is to increase the number of gas vehicles in the partner regions by 50%.

    For decades the burning of fossil fuels released a lot of pollutants in the atmosphere. Among the most harmful is sulfur dioxide (SO{sub 2}), which reacts with the moisture in the air and turns into sulfuric acid, being the main cause of acid rain. Acid rain is very harmful to animal and plant kingdoms; accelerates the corrosion's processes of buildings and monuments, and causes serious health problems for humans. As a result, many countries have reformed their legislation to require the sale of fuels with very low sulfur content. The existing processes of desulfurization are not capable of removing sulfur so low. Therefore, there has developed a new process called bio desulfurization. In this process, the degradation of sulfur occurs through the action of microorganisms that act as catalysts. The bacterium Rhodococcus erythropolis has emerged as one of the most promising for bio desulfurization because it removes the sulfur without breaking the benzene rings, thereby maintaining the potential energy of the same. Using dibenzothiophene as a model of sulfur compounds, the products of the bio desulfurization process are 2- hydroxybiphenyl and sulfate. In this study we sought to examine the desulfurizing capacity of national Rhodococcus erythropolis strain ATCC4277 in a batch reactor using concentrations of organic phase (n-dodecane) of 20 and 80% (v/v). Rhodococcus erythropolis ATCC4277 was capable of degrading DBT in 93.3 and 98.0% in the presence of 20 and 80% (v/v) of synthetic fuel, respectively. (author)

    Wood pellet manufacturing in the Intermountain West is a recently founded and rapidly expanding energy industry for small-scale producers. Within a three-year period, the total number of manufacturers in the region has increased from seven to twelve (Folk et al., 1988). Small-scale industry development is evolving because a supply of raw materials from small and some medium-sized primary and secondary wood processors that has been largely unused. For the residue producer considering pellet fuel manufacturing, the wastewood generated from primary products often carries a cost associated with residue disposal when methods at-e stockpiling, landfilling or incinerating. Regional processors use these methods for a variety of reasons, including the relatively small amounts of residue produced, residue form, mixed residue types, high transportation costs and lack of a local market, convenience and absence of regulation. Direct costs associated with residue disposal include the expenses required to own and operate residue handling equipment, costs for operating and maintaining a combustor and tipping fees charged to accept wood waste at public landfills. Economic and social costs related to environmental concerns may also be incurred to include local air and water quality degradation from open-air combustion and leachate movement into streams and drinking water.

    It is demonstrable that synthetic fuels (jet/diesel/gasoline ≅ (CH 2 ) n ) can be produced from carbon, water, and nuclear energy. What remains to be shown is that all system processes are scalable, integrable, and economical. Sources of carbon include but are not limited to CO 2 from the atmosphere or seawater, CO 2 from fossil-fired power plants, and elemental carbon from coal or biomass. For mobile defense (Navy) applications, the ubiquitous atmosphere is our chosen carbon source. For larger-scale sites such as Naval Advance Bases, the atmosphere may still be the choice should other sources not be readily available. However, at many locations suitable for defense and, potentially, commercial syn-fuel production, far higher concentrations of carbon may be available. The rationale for this study was manifold: fuel system security from terrorism and possible oil embargoes; rising demand and, eventually, peaking supply of conventional petroleum; and escalating costs and prices of fuels. For these reasons, the initial parts of the study were directed at Syn-fuel production for mobile Naval platforms and shore sites such as Rokkasho, Japan (as an exemplar). Nuclear reactors would provide the energy for H 2 from water-splitting, Membrane Gas Absorption (MGA) would extract CO 2 from the atmosphere, the Reverse Water-Gas Reaction (RWGR) would convert the CO 2 to CO, and the resultant H 2 and CO feeds would be converted to (CH 2 )n by the Fischer-Tropsch reaction. Many of these processes exist at commercial scale. Some, particularly MGA and RWGR, have been demonstrated at the bench-scale, requiring up-scaling. Likewise, the demonstration of an integrated system at some scale is yet to be done. For ship-based production, it has been shown that the system should be viable and, under reasonable assumptions, both scalable and economical for defense fuels. For the assumptions in the study, fuel cost estimates range from ∼ $2.55 to $4.75 per gallon with a nominal cost of

    Methanol synthesis from carbon dioxide, water and nuclear fusion energy is extensively investigated. The entire system is analyzed from the point of view of process design and economic evaluation of various processes. The main potential advantage of a fusion reactor (CTR) for this purpose is that it provides a large source of low cost environmentally acceptable electric power based on an abundant fuel source. Carbon dioxide is obtained by extraction from the atomsphere or from sea water. Hydrogen is obtained by electrolysis of water. Methanol is synthesized by the catalytic reaction of carbon dioxide and hydrogen. The water electrolysis and methanol synthesis units are considered to be technically and commercially available. The benefit of using air or sea water as a source of carbon dioxide is to provide an essentially unlimited renewable and environmentally acceptabe source of hydrocarbon fuel. Extraction of carbon dioxide from the atmosphere also allows a high degree of freedom in plant siting. (U.S.)

    2004-01-01

    This paper presents a fuel prices scenario generator in the frame of a simulation tool developed to support risk analysis in a competitive electricity environment. The tool feeds different erogenous risk factors to a wholesale electricity market model to perform a statistical analysis of the results. As the different fuel series that are studied, such as the oil or gas ones, present stochastic volatility and strong correlation among them, a multivariate Generalized Autoregressive Conditional Heteroskedastic (GARCH) model has been designed in order to allow the generation of future fuel prices paths. The model makes use of a decomposition method to simplify the consideration of the multidimensional conditional covariance. An example of its application with real data is also presented. (author)

    There is not enough marketing of dentistry; but there certainly is too much selling of poor quality service that is being passed off as dentistry. The marketing concept makes the patient and the patients' needs the ultimate criteria of marketing efforts. Myths and good practices for effective marketing that will promote oral health are described under the traditional four "Ps" categories of "product" (best dental care), "place" (availability), "promotion" (advertising and other forms of making patients aware of available services and how to use them), and "price" (the total cost to patients of receiving care).

    Storing hydrogen gas into cylinders under high pressure of 350 bar is not safe and still needs many intensive studies dedic ated for tank's manufacturing. Liquid hydrogen faces also severe practical difficulties due to its very low density, leading to larger fuel tanks three times larger than traditional gasoline tank. Moreover, converting hydrogen gas into liquid phase is not an economic process since it consumes high energy needed to cool down the gas temperature to -252.8 °C. One practical solution is storing hydrogen gas in metal lattice such as Mg powder and its nanocomposites in the form of MgH 2 . There are two major issues should be solved first. One related to MgH 2 in which its inherent poor hydrogenation/dehydrogenation kinetics and high thermal stability must be improved. Secondly, related to providing a safe tank. Here we have succeeded to prepare a new binary system of MgH 2 /5 wt. % TiMn 2 nanocomposite powder that show excellent hydrogenation/dehydrogenation behavior at relatively low temperature (250 °C) with long cycle-life-time (1400 h). Moreover, a simple hydrogen storage tank filled with our synthetic nanocomposite powders was designed and tested in electrical charging a battery of a cell phone device at 180 °C through a commercial fuel cell.

    Future energy systems will increasingly need to integrate variable renewable energy in order to reduce greenhouse gas emissions from power production. Addressing this trend the present paper studies how a hybrid energy systems comprising aggregated wind farms, a biomass processing plant, and a nuclear cogeneration plant could support high renewable energy penetration. The hybrid energy system operates so that its electrical output tends to meet demand. This is achieved mainly through altering the heat-to-power ratio of the nuclear reactor and by using excess electricity for hydrogen production through electrolysis. Hybrid energy systems with biomass treatment processes, i.e. drying, torrefaction, pyrolysis and synthetic fuel production were evaluated. It was shown that the studied hybrid energy system comprising a 1 GWe wind farm and a 347 MWe nuclear reactor could closely follow the power demand profile with a standard deviation of 34 MWe. In addition, on average 600 m"3 of bio-gasoline and 750 m"3 bio-diesel are produced daily. The reduction of greenhouse gas emissions of up to 4.4 MtCO_2eq annually compared to power generation and transport using conventional fossil fuel sources. (author)

    This study has examined whether the use of SNG produced from biofuels can constitute an alternative use for biofuel. Gasification technologies are studied: pressurized gasification with oxygen/steam, indirect gasification and hydrogen gasification. The objective of the project is to make a reasonable valuation of the production of SNG and through a market-study see if biofuel-based SNG can be an alternative to competing fuels. The report also discusses the supply and price of biofuels in Sweden. This use was 112 TWh in 2005 and assessed potential in year 2025 is 187 TWh. Biofuel prices show an upward trend and system of incentives affect the development of the biofuels market and price. The main incentives are electricity certificate system, energy and environmental taxes and emissions trading. Current energy and climate policies in Sweden and EU are expected to increase demand for biofuels and thus likely the prices. Increased volumes of waste tend to reduce pressure on the demand for biofuels generally. SNG is compared with natural gas and with other uses for biofuels and other competing fuels, depending on the application. The economic analysis has been conducted for three different cost levels in fuels and incentives, namely the year 2007, scenario in 2012 and scenario in 2020. The economics of SNG is evaluated for the three above-mentioned scenarios, both with respect to its cost of production, and in which market the SNG used (cogeneration, heating, industry and the automotive market). A sensitivity analysis has been conducted on the following parameters: fuel prices, electricity prices, the cost of emissions, taxes and investment. The results show that SNG is not a finished product available on the market today why additional support is required to make SNG competitive so that investment in production is stimulated. The production cost of SNG is between 380 - 410 SEK/MWh and necessary support is estimated to amount to 150 - 200 SEK/MWh on the basis of the

    2007-07-01

    In order to deal with problems such as climate change, an increasing energy demand and the finiteness of fossil resources, alternative CO{sub 2}-low technologies have to be found for a sustainable growing future. Laboratories at PSI are conducting research on two pathways delivering such car fuels: synthetic natural gas from wood gasification (SNG) and hydrogen from solar thermochemical ZnO dissociation (STD). The biofuel SNG is produced using wood in an auto-thermal gasification reactor. It can be supplied to the natural-gas grid and be used in a compressed natural gas (CNG) vehicle. STD is a long-term option, using concentrated solar radiation in a thermochemical reactor, producing zinc as solar energy carrier. Zinc can be used for hydrolysis, in order to produce hydrogen as a locally low-polluting future car fuel. In the frame of the thesis, both fuels are assessed using a life cycle assessment, i.e. investigating all environmental interactions from the extraction of resources over the processing and usage steps to the final disposal. Different methodologies are applied for a rating, compared to alternatives and standard fuels of today. In addition, costs of the technologies are calculated in order to assess economic competitiveness. The thesis is structured as follows: After an introduction giving an overview (chapter A), the methodology is presented (chapter B). It includes various life cycle impact assessment methods such as greenhouse gas emissions, the cumulative energy demand or comprehensive rating approaches. Calculations of the production and supply costs of the assessed fuels are included as well as the eco-efficiency, a combination of environmental with economic indicators. In addition, external costs caused by the emissions are quantified. Sensitivity studies investigate the importance of different parameters and substantiate conclusions. In chapter C, the production, supply and use of the assessed fuels is discussed, following the well

    2014-03-21

    Synthetic biology is frequently defined as the application of engineering design principles to biology. Such principles are intended to streamline the practice of biological engineering, to shorten the time required to design, build, and test synthetic gene networks. This streamlining of iterative design cycles can facilitate the future construction of biological systems for a range of applications in the production of fuels, foods, materials, and medicines. The promise of these potential applications as well as the emphasis on design has prompted critical reflection on synthetic biology from design theorists and practicing designers from many fields, who can bring valuable perspectives to the discipline. While interdisciplinary connections between biologists and engineers have built synthetic biology via the science and the technology of biology, interdisciplinary collaboration with artists, designers, and social theorists can provide insight on the connections between technology and society. Such collaborations can open up new avenues and new principles for research and design, as well as shed new light on the challenging context-dependence-both biological and social-that face living technologies at many scales. This review is inspired by the session titled "Design and Synthetic Biology: Connecting People and Technology" at Synthetic Biology 6.0 and covers a range of literature on design practice in synthetic biology and beyond. Critical engagement with how design is used to shape the discipline opens up new possibilities for how we might design the future of synthetic biology.

    2016-01-01

    This paper looks at the technological growth of new car fleet fuel efficiency in the European Union between 1975 and 2015. According to the analysis results, from1975 to 2006 the fuel efficiency technology improvements were largely offset by vehicles' increased weight, engine size, and consumer amenities such as acceleration capacity. After 2006, downsizing in weight and engine capacity was observed in new car fleet, while fuel consumption decreased by 32% between 2006 and 2015. We adopt a statistical method and find that from 1975 to 2015, a 1% increase in weight would result in 0.3 to 0.5% increments in fuel consumption per 100 km, and a 1% reduction in 0–100 km/h acceleration time would increase fuel consumption by about 0.3%. Impacts of other attributes on fuel consumption are also assessed. To meet the European Union's 2021 fuel consumption target, downsizing of cars, as well as at least maintaining fuel efficiency technology growth trend observed between 2005 and 2015, are needed. Government policies on controlling improvement in acceleration performance or promoting alternative fuel vehicles are also important to achieve European Union 2021 target. - Highlights: • We evaluated fuel efficiency technological growth trends in European cars. • We quantified trade-offs between vehicle attributes and fuel consumption using statistical methods. • Technology development was offset by upsizing and upgrading of cars in 1975–2006. • Technology development and downsizing enabled large improvements in efficiency in 2006–2015. • Maintaining historical trend of efficiency improvement is not enough to achieve EU 2021 target.

    This study is concerned with exploring the role of marketing as a tool to improve smart meter adoption amongst different fuel poverty groups. The traditional view of marketing is that it is a process by which people and firms get what they require and desire by generating and trading value with others (Kotler and Armstrong, 2010). Nonetheless, a more recent view of marketing is that it provides a vehicle to aid the achievement of a wide range of social goals. In this instance, fuel poverty an...

    There are a total of 33 VVER active reactors in the EU and Ukraine, accounting for the largest percentage of the total electricity supply in the countries operating these. The responsible governments and utilities operating these units want too see an increased diversification of the nuclear fuel supply. Westinghouse is the only nuclear fuel producer outside Russia, which has taken the major steps to develop, qualify and manufacture VVER fuel designs - both for VVER-440 and VVER-1000 reactors. The company has delivered reloads of VVER-440 fuel to Loviisa 2 in Finland, VVER-1000 fuel for both the initial core and follow-on regions to Temelin 1-2 in the Czech Republic and more recently reloads of VVER-1000 fuel to South Ukraine 2-3. Technical challenges in form of mechanical interference with the resident fuel have been encountered in Ukraine, but innovative solutions have been developed and successfully implemented and today Ukraine has, for the first time in its history, a viable VVER-1000 fuel design alternative, representing a tremendous lever in energy security for the country.

    2008-01-01

    Under the weakening NPT (Non-Proliferation Treaty) regime, a number of proposals and initiatives for nuclear fuel supply assurance and guarantee mechanisms have been brought on the agenda of international discussions and negotiations. This report first discusses where and why those ideas came out, and then turn to the current situations of markets of nuclear fuel materials and services in terms of degree of market concentration to specific suppliers. Based on those observations, the author attempts to draw a comparison among the proposed schemes in order to examine possible steps for forward that pose least possible influences adverse to the individual markets and thereby could better attract possible recipient states' interests. The report suggests that those initiatives are classified in three types; a) physical assurance, i.e. specific nation(s) and/or entit(-y/-ies) prepare dedicated reserve of materials and/or service capacities for the purpose of supply assurance; b) collective assurance, i.e. a group of nations and/or entities collectively submit their excess materials and service capacities when assurance is activated; and c) financial measures. In view of their feasibility, a two-step approach might be found practical to implement and promote; i.e. 1) in a short-run, a 'soft' scheme which never interferes NPT signatories' right of peaceful development and use of nuclear power could be set and implemented, and 2) in a long-run, R and D efforts should be undertaken to create such a sufficient economic margin that potential recipient states may lose justification of self-development of nuclear fuel cycle technologies and businesses when compared with those services provided by foreign sources attached with a sufficient degree of supply assurances.

    The Department of Energy has the responsibility for the shipment of spent nuclear fuel (SNF) from commercial reactors to a Federal facility for storage and/or disposal. DOE has developed a strategy for a market driven approach for the acquisition of transportation services and equipment which will maximize the participation of private industry. To implement this strategy, DOE is planning to issue a Request for Proposal (RFP) for the provision of the required services and equipment to accept SNF from the utilities and transport the SNF to a Federal facility. The paper discusses this strategy and describes the RFP

    Microbial fuel cell (MFC) is an eco-friendly bio-electrochemical sys-tem that uses microorganism as biocatalyst to convert biomass into electricity. Glycerol, as a waste in the biodiesel refinery processes, is an appealing substrate for MFC. Nevertheless, glycerol cannot be utilized as carbon source by well-known exoelectrogens such as Shewanella oneidensis. Herein, to generate electricity by rapidly harnessing glycerol, the authors rationally constructed a Klebsiella pneumoniae-Shewanella oneidensis microbial consortium to efficiently harvest electricity from glyc-erol, in which K. pneumoniae converted glycerol into lactate, fed to S. oneidensis as carbon source and electron donor. To improve electricity output, the authors systematically engineered the consortium in terms of carbon flux distribution and efficiency of extracellular electron transfer (EET). To direct more carbon flux to lactate biosynthesis in K. pneumoniae, the authors eliminated the ethanol pathway by knocking out the alcohol dehydrogenase gene (adhE), and enhanced lactate biosynthesis by heterologously expressing a lactate dehydrogen-ase gene (ldhD) from Lactobacillus bulgaricus and a lactate transporter gene (lldP) from Escherichia coli. To facilitate EET between S. oneidensis and anode surfaces, a biosynthetic flavins pathway from Bacillus subtilis is introduced into S. oneidensis. The author further optimized the glycerol concentration, thus S. oneidensis could be continuously fed with lactate synthesized from K. pneumoniae at a constant rate. Our glycerol-fed MFC generated a maximum power density of 19.9 mW/m 2 , significantly higher than that of the wild-type consor-tium. This work suggested that engineering microbial consortia is an effi-cient strategy to expand the spectrum of usable carbon sources and promote electricity power production in MFCs. © 2017 WILEY-VCH Verlag GmbH & Co.

    2003-01-01

    None of the EU directives on liberalisation of the electricity and gas markets are considering the district heating systems, although the district heating networks offer the possibility of competition between natural gas and a range of other fuels on the market for space heating. Cogeneration of electricity and heat for industrial processes or district heating is a technology option for increased energy efficiency and thus reduction of CO 2 emissions. In the mid-1990s less than 10% of the electricity generation in the European Union was combined production with significant variations among Member States. These variations are explained by different national legislation and relative power of institutions, rather than difference in industrial structure, climate or urban physical structure. The 'single energy carrier' directives have provisions that support the development of combined heat and power (CHP), but they do not support the development and expansion of the district heating infrastructure. The article is partly based on a contribution to the Shared Analysis Project for the European Commission DG Energy, concerning the penetration of CHP, energy saving, and renewables as instruments to meet the targets of the Kyoto Protocol within the liberalised European energy market. The quantitative and legal differences of the heat markets in selected Member States are described, and the consequences of the directives are discussed. Finally, we summarise the tasks for a European policy concerning the future regulation of district heating networks for CHP, emphasising the need for rules for a fair competition between natural gas and district heating networks

  4. Growing markets to sustain oil sands development

    2003-01-01

    The utilization of Alberta bitumen for the clean fuels market depends on upgrading, transportation, and refining processes. Forecasts show that oil sands production, which includes synthetic crude oil (SCO), will surpass declining conventional production in Western Canada. Several issues pose a challenge to the oil sands processing industry. The producers' market is affected by crude oil prices, market expansion options, diluent availability/cost, supply cost competitiveness, and regional processing. The common market issues include light/heavy crude prices, oil sands crude qualities, prices of oil sands crudes, pipeline infrastructure, and competitive supplies. The issues facing the refiners are: refining margins, security of crude supply, refined product quality, and competitive product supply. A brief review of markets for Canadian crude oil, including synthetic crude, was provided. The share of the Midwest market by Alberta must be retained and increased. The market expansion options were reviewed for both downstream (refining) and upstream (upgrading) operations. To reach more distant markets such as Southern Midwest, Washington, and California, new pipeline capacity would be required. The market is nearly saturated for Canada's heavy oil supply. More upgrading will be required as bitumen production increases. Market growth is still possible for Canada's SCO but according to forecasts, the market could also become saturated. To increase demand and allow supplies to grow, SCO prices may fall below light crude prices. It was noted that a balance must be achieved in order for producers to increase production and for refiner/upgraders to expand their conversion capacity. tabs., figs

    The market for ethanol has grown from approximately 1.2 billion gallons in 1997 to almost 5 billion gallons in 2006. With the huge increase in ethanol demand in recent years, the growth in derived demand for corn has driven up many food prices. This paper uses monthly data from 1997-2006 to estimate the market supply and demand for ethanol at the national level. The simultaneous determination of the supply and demand curves using two-stage least squares allows for the calculation of supply and demand-side elasticities, which are important results in light of the tremendous growth in this market and recent legislation concerning ethanol.

    Bautin, F.; Martin-Amouroux, J.M.

    2007-01-01

    The share of coal in the world energy mix (25%) and its possible increase during the next decades is due to its specific use in steelmaking industry and to its excellent competitiveness in fossil-fuel power plants with respect to other energy sources. Its inferior energy efficiency is compensated by lower and more stable prices on international markets. This situation is explained by a strong competition and abundant reserves. However, coal is a strong emitter of greenhouse gases and would be temporarily penalized by the implementation of emission tax or trading systems before the development of carbon sequestration systems. This article presents: the main world markets (consumption per sector of activity, power generation market, coke market, start-up of a synthetic fuels market), the main international coal producers and traders (overview and typology, international trades, transport), the reserves and resources, and the worldwide perspectives (2050 scenarios, climatic risks, CO 2 prices and technological changes).

    1996-01-01

    In this report, estimates are provided of the potential, by 2010, to displace conventional light-duty vehicle motor fuels with alternative fuels--compressed natural gas (CNG), liquefied petroleum gas (LPG), methanol from natural gas, ethanol from grain and from cellulosic feedstocks, and electricity--and with replacement fuels such as oxygenates added to gasoline. The 2010 estimates include the motor fuel displacement resulting both from government programs (including the Clean Air Act and EPACT) and from potential market forces. This report also provides an estimate of motor fuel displacement by replacement and alterative fuels in the year 2000. However, in contrast to the 2010 estimates, the year 2000 estimate is restricted to an accounting of the effects of existing programs and regulations. 27 figs., 108 tabs.

  15. Refueling availability for alternative fuel vehicle markets: Sufficient urban station coverage

    2008-01-01

    Alternative fuel vehicles can play an important role in addressing the challenges of climate change, energy security, urban air pollution and the continued growth in demand for transportation services. The successful commercialization of alternative fuels for vehicles is contingent upon a number of factors, including vehicle cost and performance. Among fuel infrastructure issues, adequate refueling availability is one of the most fundamental to successful commercialization. A commonly cited source reports 164,300 refueling stations in operation nationwide. However, from the perspective of refueling availability, this nationwide count tends to overstate the number of stations required to support the widespread deployment of alternative fuel vehicles. In terms of spatial distribution, the existing gasoline station networks in many urban areas are more than sufficient. We characterize a sufficient level of urban coverage based upon a subset of cities served by relatively low-density station networks, and estimate that some 51,000 urban stations would be required to provide this sufficient level of coverage to all major urban areas, 33 percent less than our estimate of total urban stations. This improved characterization will be useful for engineering, economic and policy analyses. (author)

    Full Text Available Synthetic cannabinoids which is a subgroup of cannabinoids are commonly used for recreational drug use throughout the whole world. Although both marijuana and synthetic cannabinoids stimulate the same receptors, cannabinoid receptor 1 (CB1 and cannabinoid receptor 2 (CB2, studies have shown that synthetic cannabinoids are much more potent than marijuana. The longer use of synthetic cannabinoids can cause severe physical and psychological symptoms that might even result in death, similar to many known illicit drugs. Main treatment options mostly involve symptom management and supportive care. The aim of this article is to discuss clinical and pharmacological properties of the increasingly used synthetic cannabinoids.

  1. Influence of the pro-ecological tax on the market prices of fuels and electricity

    International Nuclear Information System (INIS)

    Szargut, Jan; Stanek, Wojciech

    2008-01-01

    The proposed pro-ecological tax should be proportional to the cumulative consumption of non-renewable natural exergy burdening the considered product. It should replace the existing value-added tax (VAT). The income of the state after introducing the new tax, should remain without any change. That principle determines the coefficient of proportionality between the cumulative consumption of non-renewable exergy and the value of the tax. The total value of the tax should be paid to the state after extracting the minerals and fuels from nature and importing the fuels and semi-finished products, then transferred to the subsequent products in a form of their elevated price. Hence, the tax is eventually paid by the consumers in the form of an elevated price of goods and services. The total income of the society should remain without any changes. The largest price increase will appear in the case of fuels and electricity. The prices of electricity produced from renewable resources are calculated too, taking into account the accompanying unavoidable consumption of non-renewable exergy for the construction of the power plant. The new VAT should enhance the economy of the most energy-consuming products, stimulate the mitigation of the total consumption level of the society and increase the application of the renewable energy resources.

    Nuclear materials declared by the US and Russian governments as surplus to defense programs are being converted into fuel for commercial nuclear reactors. This report presents the results of an analysis estimating the market effects that would likely result from current plans to commercialize surplus defense inventories. The analysis focuses on two key issues: (1) the extent by which traditional sources of supply, such as production from uranium mines and enrichment plants, would be displaced by the commercialization of surplus defense inventories or, conversely, would be required in the event of disruptions to planned commercialization, and (2) the future price of uranium considering the potential availability of surplus defense inventories. Finally, the report provides an estimate of the savings in uranium procurement costs that could be realized by US nuclear power generating companies with access to competitively priced uranium supplied from surplus defense inventories.

    Electric vehicles are expected to significantly reduce road transport emissions, given an increasingly renewable power generation. While technological issues are more and more being overcome, the economic viability and thus possible adoption is still constrained, mainly by higher prices than for conventional vehicles. In our work we analyze possible market developments for electric vehicles with an application to Germany. We develop a drivetrain choice model with economical, technical and social constraints on the current vehicle registrations and inventory. It estimates the demand for electric vehicles until 2030 for private and commercially registered cars as well as light commercial vehicles. The results show a replacement potential of almost one third of the total German annual mileage for these vehicles. The result has a high granularity to allow for detailed emission calculation along different spatial areas as well as vehicle and engine types. Besides a baseline forecast, our method allows for calculating different scenarios regarding policy actions or the future development of important parameters such as energy prices. The results provide insights for policy measures as well as for transport and environmental modeling. - Highlights: • We model the potential German market for electric vehicles using total cost of ownership. • The results show a substitution potential of one third of the total German annual mileage. • Plug-in hybrid drivetrains outperform battery electric ones due to their cost advantages. • Suburbia around large cities is the largest market for EVs. • The first main vehicle categories for EVs are large and medium-sized company cars

    In order to meet rapidly growing demand for fuel, as well as address environmental concerns, the aviation industry has been testing alternate fuels for performance and technical usability in commercial and military aircraft. Currently, alternate aviation fuels must satisfy MIL-DTL- 83133F(2008) (military) or ASTM D 7566- Annex(2011) (commercial) standards and are termed drop-in fuel replacements. Fuel blends of up to 50% alternative fuel blended with petroleum (JP-8), which have become a practical alternative, are individually certified on the market. In order to make alternate fuels (and blends) a viable option for aviation, the fuel must be able to perform at a similar or higher level than traditional petroleum fuel. They also attempt to curb harmful emissions, and therefore a truly effective alternate fuel would emit at or under the level of currently used fuel. This paper analyzes data from gaseous and particulate emissions of an aircraft combustor sector. The data were evaluated at various inlet conditions, including variation in pressure and temperature, fuel-to-air ratios, and percent composition of alternate fuel. Traditional JP-8+100 data were taken as a baseline, and blends of JP- 8+100 with synthetic-paraffinic-kerosene (SPK) fuel (Fischer-Tropsch (FT)) were used for comparison. Gaseous and particulate emissions, as well as flame luminosity, were assessed for differences between FT composition of 0%, 50%, and 100%. The data showed that SPK fuel (a FT-derived fuel) had slightly lower harmful gaseous emissions, and smoke number information corroborated the hypothesis that SPK-FT fuels are cleaner burning fuels.

    Full Text Available The advancement of microbial processes for the production of renewable liquid fuels has increased with concerns about the current fuel economy. The development of advanced biofuels in particular has risen to address some of the shortcomings of ethanol. These advanced fuels have chemical properties similar to petroleum-based liquid fuels, thus removing the need for engine modification or infrastructure redesign. While the productivity and titers of each of these processes remains to be improved, progress in synthetic biology has provided tools to guide the engineering of these processes through present and future challenges.

    The Advanced Distributed Simulation (ADS) Synthetic Environments Program seeks to create robust virtual worlds from operational terrain and environmental data sources of sufficient fidelity and currency to interact with the real world. While some applications can be met by direct exploitation of standard digital terrain data, more demanding applications -- particularly those support operations 'close to the ground' -- are well-served by emerging capabilities for 'value-adding' by the user working with controlled imagery. For users to rigorously refine and exploit controlled imagery within functionally different workstations they must have a shared framework to allow interoperability within and between these environments in terms of passing image and object coordinates and other information using a variety of validated sensor models. The Synthetic Environments Program is now being expanded to address rapid construction of virtual worlds with research initiatives in digital mapping, softcopy workstations, and cartographic image understanding. The Synthetic Environments Program is also participating in a joint initiative for a sensor model applications programer's interface (API) to ensure that a common controlled imagery exploitation framework is available to all researchers, developers and users. This presentation provides an introduction to ADS and the associated requirements for synthetic environments to support synthetic theaters of war. It provides a technical rationale for exploring applications of image understanding technology to automated cartography in support of ADS and related programs benefitting from automated analysis of mapping, earth resources and reconnaissance imagery. And it provides an overview and status of the joint initiative for a sensor model API.

    The Office of Civilian Radioactive Waste Management (OCRWM) in the United States Department of Energy (DOE) has the responsibility under the Nuclear Waste Policy Act of 1982 (the Act) for the shipment of spent nuclear fuel (SNF) from commercial reactors to a Federal facility for storage and/or disposal. The Act requires the use of private industry to the 'fullest extent possible' in the transportation of spent fuels. An OCRWM goal is to develop a safe, efficient and effective transportation system while meeting the mandate of the Act. OCRWM has then develop a strategy for a market driven approach for the acquisition of transportation services and equipment. To implement this strategy, OCRWM is planning to issue a Request for Proposal (RPF) for the provision of the required services and equipment to accept SNF from the utilities and transport the SNF to a Federal facility. Two draft RPFs have been issued with the second draft incorporating comments on the first draft from potential contractors and other interested parties. The overall strategy as outlined in the draft RPF relies on private industry to use the innovative powers of the marketplace to help DOE accomplish its mission objectives. DOE intends to pursue this procurement strategy whether or not the OCRWM program includes interim storage. The concept described in the draft RPF provides for DOE to purchase services and equipment from a contractor-operated waste acceptance and transportation organization. The contractor is expected to provide initial financing for the project including that necessary for initial acquisition of operational equipment, establish the necessary management organization, and mobilize the necessary resources and capabilities to provide the SNF delivery services at a fixed rate. DOE will retain final approval on all routes and maintain primary responsibility to the States, tribes, and local units of government for assuring appropriate interaction and consideration of their input on

    Hydrogen is usually presented as a promising energy carrier that has a major role to play in low carbon mobility, through the use of fuel cells. However, such a market is not expected in the short term. In the meantime, hydrogen may also contribute to reduce carbon emissions in diverse sectors: oil refining, low carbon mobility through the industrial deployment of advanced bio-fuels, natural gas consumption, and methanol production. According to the targeted market, objective costs are rather different; and so is the reachable mitigated CO 2 amount. This paper assesses the dynamics of these markets' attractiveness, in order to provide target costs for CO 2 -free hydrogen production. The potential of the markets of hydrogen as a fuel and hydrogen for the biomass-to-liquid production is highlighted, as they could represent significant volumes by 2050, as well as interesting perspectives for CO 2 emission reduction. However the targets are very sensitive to the CO 2 price, thus highlighting the requirement for economic instruments in order to facilitate the penetration of such technologies. Hydrogen is then highlighted as a key player of the energy system in the years to come, as the connection of the energy and mobility sectors. (authors)

  12. Enabling the Distributed Generation Market of High Temperature Fuel Cell and Absorption Chiller Systems to Support Critical and Commercial Loads

    DiMola, Ashley M.

    Buildings account for over 18% of the world's anthropogenic Greenhouse Gas (GHG) emissions. As a result, a technology that can offset GHG emissions associated with buildings has the potential to save over 9 Giga-tons of GHG emissions per year. High temperature fuel cell and absorption chiller (HTFC/AC) technology offers a relatively low-carbon option for meeting cooling and electric loads for buildings while producing almost no criteria pollutants. GHG emissions in the state of California would decrease by 7.48 million metric tons per year if every commercial building in the State used HTFC/AC technology to meet its power and cooling requirements. In order to realize the benefits of HTFC/AC technology on a wide scale, the distributed generation market needs to be exposed to the technology and informed of its economic viability and real-world potential. This work characterizes the economics associated with HTFC/AC technology using select scenarios that are representative of realistic applications. The financial impacts of various input factors are evaluated and the HTFC/AC simulations are compared to the economics of traditional building utilities. It is shown that, in addition to the emissions reductions derived from the systems, HTFC/AC technology is financially preferable in all of the scenarios evaluated. This work also presents the design of a showcase environment, centered on a beta-test application, that presents (1) system operating data gathered using a custom data acquisition module, and (2) HTFC/AC technology in a clear and approachable manner in order to serve the target audience of market stakeholders.

    A fuel quality processing study to provide a data base for an intelligent tradeoff between advanced turbine technology and liquid fuel quality, and also, to guide the development of specifications of future synthetic fuels anticipated for use in the time period 1985 to 2000 is given. Four technical performance tests are discussed: on-site pretreating, existing refineries to upgrade fuels, new refineries to upgrade fuels, and data evaluation. The base case refinery is a modern Midwest refinery processing 200,000 BPD of a 60/40 domestic/import petroleum crude mix. The synthetic crudes used for upgrading to marketable products and turbine fuel are shale oil and coal liquids. Of these syncrudes, 50,000 BPD are processed in the existing petroleum refinery, requiring additional process units and reducing petroleum feed, and in a new refinery designed for processing each syncrude to produce gasoline, distillate fuels, resid fuels, and turbine fuel, JPGs and coke. An extensive collection of synfuel properties and upgrading data was prepared for the application of a linear program model to investigate the most economical production slate meeting petroleum product specifications and turbine fuels of various quality grades. Technical and economic projections were developed for 36 scenarios, based on 4 different crude feeds to either modified existing or new refineries operated in 2 different modes to produce 7 differing grades of turbine fuels. A required product selling price of turbine fuel for each processing route was calculated. Procedures and projected economics were developed for on-site treatment of turbine fuel to meet limitations of impurities and emission of pollutants.

  15. Evaluation of the uranium market and its consequences in the strategy of a nuclear fuel supplier that is also a uranium producer

    Esteves, R.G.

    2005-01-01

    On January 2005, the uranium spot market price reached the value of $21.00/lbU3O8. One month before, at the end of December, the average price was $20.70/lbU3O8 and in November the spot price registered $20.50. When we review this abstract, on July 2005, the price has reached $30.00/lbU3O8. In 1984, the uranium spot price dropped below the twenties and remained so reaching meanwhile even one-digit values, even considering that the uranium offer in this period was always below the demand. The main reason for that distortion in the market was and still is, the interference of the developing countries governments after the end of the cold war The Industrias Nucleares do Brasil - INB is in an odd situation in the market of fuel suppliers due to being also a uranium producer and in short future will also be an enrichment services supplier. This peculiar position brings additional advantages due to the flexibility to play with the uranium costs versus tail assay to optimize its nuclear fuel costs. That odd position, equivalent only in the market to AREVA, allows INB to exchange uranium by SWU and vice versa according to its uranium cost (not market sell price) and in the future to the SWU's costs obtaining a better margin that can not be reached by other fuel suppliers. In the first part of this paper it is evaluated, based on the recent market information, the consequences in the 2004 uranium spot price, expected to be more emphasized during 2005. This paper also evaluate the market mechanisms for expecting the price to cross the $40/lbU3O8 in short time The market supply mechanisms used up to now to fulfil the market deficit may be interrupted in case the developing countries governments stop the availability of the non civil uranium reserves from its stockpile. Different hypotheses for supplying the primary uranium deficit in this last case are analyzed in this work and evaluated its consequences.

    This study has made an inventory of 53 governmental interventions in the Dutch energy market. Moreover, the consequences for the playing field for fossil fuels, renewable sources, nuclear energy and energy saving have been quantified. It shows that the government still stimulates the use of energy and fossil fuels more than it stimulates use of renewable energy sources. Policy that focuses on decreasing the price differences between sustainable and fossil should therefore focus on the phase-out of this support and subsequently on bridging the remaining financial gap.

    In order to cope with climate change, the development and deployment of Hydrogen Fuel Cell Vehicles (HFCVs) is becoming more important. In this study, we developed a forecasting model for HFCVs based on the generalized Bass diffusion model and a simulation model using system dynamics. Through the developed model, we could forecast that the saturation of HFCVs in Korea can be moved up 12 years compared with the US. A sensitivity analysis on external variables such as price reduction rates of HFCVs and number of hydrogen refueling stations is also conducted. The results of this study can give insights on the effects of external variables on the market penetration of HFCVs, and the developed model can also be applied to other studies in analyzing the diffusion effects of HFCVs. - Highlights: → A forecasting model for HFCVs was developed using the generalized Bass diffusion model. → A simulation model using system dynamics was also developed. → The empirical study shows that the infrastructure is an important factor to the initial purchase. → The results of this study can promote research related to the diffusion of innovation.

    Have the radioactivity leaks from spent nuclear fuel casks conveyed to waste management sites in Germany left a stain on the image of the electric power companies? The Bielefeld-based Emnid Institute, unit for energy market research, carried out an opinion poll among the population late in May and again in mid-June 1998, in oder to find out whether the leaking casks have blemished the image of the nuclear power industry. Another aspect inquired was the expectations of the population in connection with the deregulation of the electric power market. (orig./CB) [de

    In 2008, the National Renewable Energy Laboratory (NREL), under contract to the US Department of Energy (DOE), conducted a manufacturing readiness assessment (MRA) of fuel cell systems and fuel cell stacks for back-up power and material handling applications (MHE). To facilitate the MRA, manufacturing readiness levels (MRL) were defined that were based on the Technology Readiness Levels previously established by the US Department of Energy (DOE). NREL assessed the extensive existing hierarchy of MRLs developed by Department of Defense (DoD) and other Federal entities, and developed a MRL scale adapted to the needs of the Fuel Cell Technologies Program (FCTP) and to the status of the fuel cell industry. The MRL ranking of a fuel cell manufacturing facility increases as the manufacturing capability transitions from laboratory prototype development through Low Rate Initial Production to Full Rate Production. DOE can use MRLs to address the economic and institutional risks associated with a ramp-up in polymer electrolyte membrane (PEM) fuel cell production. In 2010, NREL updated this assessment, including additional manufacturers, an assessment of market developments since the original report, and a comparison of MRLs between 2008 and 2010.

    1997-01-01

    Some of the factors affecting a refiner's choice of crude oil include refinery hardware, particularly gas oil crackers, products slate and product specifications, crude availability, relative crude price and crude quality. An overview of synthetic crude, the use of synthetic crude combined with other crudes and a comparison of synthetic crude with conventional crude oil was given. The two main users of synthetic crude are basically two groups of refiners, those large groups who use synthetic crude combined with other crudes, and a smaller group who run synthetic crude on specially designed units as a sole feed. The effects of changes in fuel legislation were reviewed. It was predicted that the changes will have a mixed impact on the value of synthetic crude, but low sulphur diesel regulations and gasoline sulphur regulations will make current synthetic crudes attractive. The big future change with a negative impact will be diesel cetane increases to reduce engine emissions. This will reduce synthetic crude attractiveness due to distillate yields and quality and high gas oil yields. Similarly, any legislation limiting aromatics in diesel fuel will also make synthetic crudes less attractive. Problems experienced by refiners with hardware dedicated to synthetic crude (salt, naphthenic acid, fouling, quality variations) were also reviewed. 3 tabs

    Full Text Available Despite comparative figures for wordwide crude oil and natural gas proven reserves, present time contribution of syngas chemistry to motorfuels remains marginal when the refining industry is faced to main constraints: market demand evolution, stringent specifications and environmental issues. Actually natural gas upgrading via syngas chemistry yields key products (e. g. methanol among which clean motorfuels (ethers, FT products should develop despite the huge investments required, mostly for syngas production. Main challenges and corresponding issues for catalysts and related technologies are identified for Fischer-Tropsch synthesis and motorfuels long-term reformulation. Among other, mastering the chain-growth (FT synthesis improving the FCC products: gasoline, and LCO for Diesel pool. All these issues need significant progresses in catalyst and technology to be solved. Lastly, our economical study, focused on Diesel-fuel production, shows up that clean diesel (from SR-LCO mixtures and FT Diesel reach similar production costs when cheap NG is available. In the future, FT middle distillates should amount to a few percent (5-150 Mt of the 1700-2000 Mt of transport middle distillates expected from oil refining. However they should more and more be a compulsory part of diesel pool if the level of investment for an FT process continues to decrease significantly. Malgré des réserves prouvées en pétrole et en gaz du même ordre de grandeur, la contribution de la chimie du gaz de synthèse à la production de carburants reste marginale, alors que l'industrie du raffinage est confrontée à des contraintes majeures : évolution de la demande, durcissement des spécifications des produits et contraintes environnementales.

    In this draft, we discuss the play of importation in the Brazilian fuel market. After two years, one would be allowed to state how effective importation is and we analyze the structural restriction in the sector. For that, we illustrate these ideas with the theoretical pricing for the gap between import parity and export parity, with data for the gasoline and heating oil domestic prices, with the quantum of importation. For one hand, this simple analyze not allow the rejection of the import parity pricing. For the other hand, we suggest this market maybe not contestable by importation. Also, it seems that importation would not be enough for eliminate anti competitive conduct in this market. (author)

    In this review, we address recent advances in the field of synthetic biology and describe how those tools have been applied to produce a wide variety of chemicals in microorganisms. Here we classify the expansion of the synthetic biology toolbox into three different categories based on their primary function in strain engineering-for design, for construction, and for optimization. Next, focusing on recent years, we look at how chemicals have been produced using these new synthetic biology tools. Advances in producing fuels are briefly described, followed by a more thorough treatment of commodity chemicals, specialty chemicals, pharmaceuticals, and nutraceuticals. Throughout this review, an emphasis is placed on how synthetic biology tools are applied to strain engineering. Finally, we discuss organism and host strain diversity and provide a future outlook in the field.

    Initial results obtained for a flow 1 H nuclear magnetic resonance (NMR) detector directly coupled to a liquid chromatography unit are described. Results achieved for a model mixture and several jet fuel samples are discussed. Chromatographic separation of alkanes, alkylbenzenes, and substituted naphthalenes present in the jet fuel samples are easily identified with the 1 H NMR detector. Results with our present flow 1 H NMR insert indicate that 5-Hz linewidths are readily obtainable for typical chromatographic flow rates. The limitations and advantages of this liquid chromatography detector are compared with more commonly employed detectors (e.g., refractive index detectors). 11 figures

    The use of Alberta bitumen as a clean fuel depends on upgrading, transportation, and refining processes. Forecasts show that oil sands production, which includes synthetic crude oil (SCO), will surpass declining conventional production from the Western Canada Sedimentary Basin. The challenges facing the oils sands processing industry include: crude oil prices which affect the producer's market; market expansion options; diluent availability/cost; supply cost competitiveness; and, regional processing. The common market issues include light/heavy crude prices, oil sands crude qualities, prices of oil sands crudes, pipeline infrastructure, and competitive supplies. The issues facing the refiners are: refining margins, security of crude supply, refined product quality, and competitive product supply. It was noted that Alberta must retain or increase its share of the Midwest market. The market expansion options were reviewed for both downstream (refining) and upstream (upgrading) operations. New pipeline capacity is needed to reach more distant markets such as Southern Midwest, Washington, and California. The market is nearly saturated for Canada's heavy oil supply. More upgrading will be required as bitumen production increases. Market growth is still possible for Canada's SCO but according to forecasts, the market could also become saturated. To increase demand and allow supplies to grow, SCO prices may fall below light crude prices. It was noted that a balance must be achieved in order for producers to increase production and for refiner/upgraders to expand their conversion capacity. 13 figs

    Synthetic cannabinoids (SCBs), also known under the brand names of "Spice," "K2," "herbal incense," "Cloud 9," "Mojo" and many others, are becoming a large public health concern due not only to their increasing use but also to their unpredictable toxicity and abuse potential. There are many types of SCBs, each having a unique binding affinity for cannabinoid receptors. Although both Δ-tetrahydrocannabinol (THC) and SCBs stimulate the same receptors, cannabinoid receptor 1 (CB1) and cannabinoid receptor 2 (CB2), studies have shown that SCBs are associated with higher rates of toxicity and hospital admissions than is natural cannabis. This is likely due to SCBs being direct agonists of the cannabinoid receptors, whereas THC is a partial agonist. Furthermore, the different chemical structures of SCBs found in Spice or K2 may interact in unpredictable ways to elicit previously unknown, and the commercial products may have unknown contaminants. The largest group of users is men in their 20s who participate in polydrug use. The most common reported toxicities with SCB use based on studies using Texas Poison Control records are tachycardia, agitation and irritability, drowsiness, hallucinations, delusions, hypertension, nausea, confusion, dizziness, vertigo and chest pain. Acute kidney injury has also been strongly associated with SCB use. Treatment mostly involves symptom management and supportive care. More research is needed to identify which contaminants are typically found in synthetic marijuana and to understand the interactions between different SBCs to better predict adverse health outcomes.

    2011-01-01

    This article presents a dynamic Generalized Nash-Cournot model to describe the evolution of the natural gas markets. The major players along the gas chain are depicted including: producers, consumers, storage and pipeline operators, as well as intermediate local traders. Our economic structure description takes into account market power and the demand representation tries to capture the possible fuel substitution that can be made between the consumption of oil, coal, and natural gas in the overall fossil energy consumption. We also take into account long-term contracts in an endogenous way, which makes the model a Generalized Nash Equilibrium problem. We discuss some means to solve such problems. Our model has been applied to represent the European natural gas market and forecast, until 2030, after a calibration process, consumption, prices, production, and natural gas dependence. A comparison between our model, a more standard one that does not take into account energy substitution, and the European Commission natural gas forecasts is carried out to analyze our results. Finally, in order to illustrate the possible use of fuel substitution, we studied the evolution of the natural gas price as compared to the coal and oil prices. (authors)

    KAUST Repository

    Wan, Y.

    2013-06-01

    Brainbow is a genetic engineering technique that randomly colorizes cells. Biological samples processed with this technique and imaged with confocal microscopy have distinctive colors for individual cells. Complex cellular structures can then be easily visualized. However, the complexity of the Brainbow technique limits its applications. In practice, most confocal microscopy scans use different florescence staining with typically at most three distinct cellular structures. These structures are often packed and obscure each other in rendered images making analysis difficult. In this paper, we leverage a process known as GPU framebuffer feedback loops to synthesize Brainbow-like images. In addition, we incorporate ID shuffing and Monte-Carlo sampling into our technique, so that it can be applied to single-channel confocal microscopy data. The synthesized Brainbow images are presented to domain experts with positive feedback. A user survey demonstrates that our synthetic Brainbow technique improves visualizations of volume data with complex structures for biologists.

    Plants are attractive platforms for synthetic biology and metabolic engineering. Plants' modular and plastic body plans, capacity for photosynthesis, extensive secondary metabolism, and agronomic systems for large-scale production make them ideal targets for genetic reprogramming. However, efforts in this area have been constrained by slow growth, long life cycles, the requirement for specialized facilities, a paucity of efficient tools for genetic manipulation, and the complexity of multicellularity. There is a need for better experimental and theoretical frameworks to understand the way genetic networks, cellular populations, and tissue-wide physical processes interact at different scales. We highlight new approaches to the DNA-based manipulation of plants and the use of advanced quantitative imaging techniques in simple plant models such as Marchantia polymorpha. These offer the prospects of improved understanding of plant dynamics and new approaches to rational engineering of plant traits.

    2009-02-11

    The notion of"productive use" is often invoked in discussions about whether new technologies improve productivity or otherwise enhance commerce in developing-country contexts. It an elusive concept,especially when quantitative measures are sought. Improved and more energy efficient illumination systems for off-gridapplication--the focus of the Lumina Project--provide a case in which a significant productivity benefit can be imagined, given the importance of light to the successful performance of many tasks, and the very low quality of baseline illumination provided by flame-based source. This Research Note summarizes self-reported quantitative and qualitative impacts of switching to LED lighting technology on the prosperity of night-market business owners and operators. The information was gathered in the context of our 2008 market testing field work in Kenya?s Rift Valley Province, which was performed in the towns of Maai Mahiu and Karagita by Arne Jacobson, Kristen Radecsky, Peter Johnstone, Maina Mumbi, and others. Maai Mahiu is a crossroads town; provision of services to travelers and freight carriers is a primary income source for the residents. In contrast, the primary income for Karagita's residents is from work in the large, factory style flower farms on the eastern shores of Lake Naivasha that specialize in producing cut flowers for export to the European market. According to residents, both towns had populations of 6,000 to 8,000 people in June 2008. We focused on quantifying the economics of fuel-based and LED lighting technology in the context of business use by night market vendors and shop keepers. Our research activities with the business owners and operators included baseline measurement of their fuel-based lighting use, an initial survey, offering for sale data logger equipped rechargeable LED lamps, monitoring the adoption of the LED lamps, and a follow-up survey.

    "Are we alone?" is one of the primary questions of astrobiology, and whose answer defines our significance in the universe. Unfortunately, this quest is hindered by the fact that we have only one confirmed example of life, that of earth. While this is enormously helpful in helping to define the minimum envelope for life, it strains credulity to imagine that life, if it arose multiple times, has not taken other routes. To help fill this gap, our lab has begun using synthetic biology - the design and construction of new biological parts and systems and the redesign of existing ones for useful purposes - as an enabling technology. One theme, the "Hell Cell" project, focuses on creating artificial extremophiles in order to push the limits for Earth life, and to understand how difficult it is for life to evolve into extreme niches. In another project, we are re-evolving biotic functions using only the most thermodynamically stable amino acids in order to understand potential capabilities of an early organism with a limited repertoire of amino acids.

    This paper described the development of a titanium (Ti/TiO{sub 2}) polyaniline composite electrode. The electrode was designed for use with a microbial fuel cell (MFC) that generated electricity through the microbial biodegradation of organic compounds. A modified NBAF medium was used with a 20 mM acetate as an electron donor and 53 mM fumarate as an electron acceptor for a period of 96 hours at 37 degrees C. Strains were cultured under strict anaerobic conditions. Two microbial cultures were used: (1) pure cultures of Geobacter sulfur-reducens; and (2) an uncharacterized stable microbial consortia isolated from hypersaline swamp sediments. The anodes were made with an emeraldine form of PANI deposited over Ti/TiO{sub 2} electrodes. Electrochemical impedance spectroscopy (EIS) monitoring was used to determine the open circuit potential of the MFC. Negative real impedances were obtained and reproduced in all systems studied with the Ti/TiO{sub 2}-PANI anodes. The highest power density was obtained using the Geobacter sulfur-reducens culture. Further research is needed to study the mechanisms that contribute to the occurrence of negative real impedances. 23 refs., 1 tab., 5 figs.

    A parametric analysis has been carried out for testing the sensitivity of the synfuel production cost in relation to crucial economic and technologic quantities (investment costs of hybrid and synfuel plant, energy multiplication of the fission blanket, recirculating power fraction of the fusion driver, etc.). In addition, a minimum synfuel selling price has been evaluated, from which the fission--fusion--synfuel complex brings about a higher economic benefit than does the fusion--fission hybrid entirely devoted to fissile-fuel and electricity generation. Assuming an electricity cost of 2.7 cents/kWh, an annual investment cost per power unit of 4.2 to 6 $/GJ (132 to 189 k$/MWty) for the fission--fusion complex and 1.5 to 3 $/GJ (47 to 95 k$/MWty) for the synfuel plant, the synfuel production net cost (i.e., revenue = cost) varies between 6.5 and 8.6 $/GJ. These costs can compete with those obtained by other processes (natural gas reforming, resid partial oxidation, coal gasification, nuclear fission, solar electrolysis, etc.). This study points out a potential use of the fusion--fission hybrid other than fissile-fuel and electricity generation

    The existence of anti competitive conduct such as cartels would lead to a situation of high prices and profits harming competition and society in general. The methodology of economic analysis of evidence of cartel by the ANP in the resale market of fuels involves analysis of the behavior of the average prices of resale and distribution, the nominal average gross margin on resale, the coefficient of variation of prices of resale and distribution of fuel for a given period by the municipality. Combining the analysis of these elements, the ANP has suggested the investigation into possible cartels. This text aims to bring contributions for a better definition of the relevant market in the analysis of economic evidence in cartel in the market for resale of fuel and add elements currently not considered in the analysis of ANP and regulation of the sector. To this end, this article is organized into three sections besides the introduction and final consideration. The first section takes place at the constitution some myths about cartels thread reseller retailer of automotive fuel by analyzing the main causes leading to complaints by consumers. Then presents a conceptual analysis of relevant market, since this definition is essential to characterize anti-competitive practices of operations performed by companies holding market power, notably the formation of cartels. Finally, it is a discussion on how the action of the main bodies involved in dismantling of anti competitive practices in the industry. Expected to find results that work with greater integration between agencies to safeguard competition and better defining the relevant market segment for the resale of fuel. (author)

  7. US Competitiveness in Synthetic Biology.

    Synthetic biology is an emerging technical field that aims to make biology easier to engineer; the field has applications in strategically important sectors for the US economy. While the United States currently leads in synthetic biology R&D, other nations are heavily investing in order to boost their economies, which will inevitably diminish the US leadership position. This outcome is not entirely negative--additional investments will expand markets--but it is critical that the US government take steps to remain competitive: There are applications from which the US population and economy may benefit; there are specific applications with importance for national defense; and US technical leadership will ensure that US experts have a leading role in synthetic biology governance, regulation, and oversight. Measures to increase competitiveness in S&T generally are broadly applicable for synthetic biology and should be pursued. However, the US government will also need to take action on fundamental issues that will affect the field's development, such as countering anti-GMO (genetically modified organism) sentiments and anti-GMO legislation. The United States should maintain its regulatory approach so that it is the product that is regulated, not the method used to create a product. At the same time, the United States needs to ensure that the regulatory framework is updated so that synthetic biology products do not fall into regulatory gaps. Finally, the United States needs to pay close attention to how synthetic biology applications may be governed internationally, such as through the Nagoya Protocol of the Convention on Biological Diversity, so that beneficial applications may be realized.

    Synthetic biology - the design and construction of new biological parts and systems and the redesign of existing ones for useful purposes - has the potential to transform fields from pharmaceuticals to fuels. Our lab has focused on the potential of synthetic biology to revolutionize all three major parts of astrobiology: Where do we come from? Where are we going? and Are we alone? For the first and third, synthetic biology is allowing us to answer whether the evolutionary narrative that has played out on planet earth is likely to have been unique or universal. For example, in our lab we are re-evolving the biosynthetic pathways of amino acids in order to understand potential capabilities of an early organism with a limited repertoire of amino acids and developing techniques for the recovery of metals from spent electronics on other planetary bodies. And what about the limits for life? Can we create organisms that expand the envelope for life? In the future synthetic biology will play an increasing role in human activities both on earth, in fields as diverse as human health and the industrial production of novel bio-composites. Beyond earth, we will rely increasingly on biologically-provided life support, as we have throughout our evolutionary history. In order to do this, the field will build on two of the great contributions of astrobiology: studies of the origin of life and life in extreme environments.

    'Full text:' Even though fuel cell technology has been known in industry for decades now, it has come to the fore in recent years hand in hand with renewable energy sources and the hydrogen vector, as a clean, reliable and efficient electric energy source. Within the stationary applications of fuel cells, the production of high output electric energy has always stood out and this could range from several hundreds of watts to megawatts to supply large plants. The objective of this project is to develop, construct and experimentally validate an electric energy generating system for domestic applications of up to 2 kW. This is due to the fact that multiple domestic applications currently exist for which an electric output of 2 kW is sufficient. On the other hand, an electricity supply might not exist, or might be deficient; and this system will enable electricity supply even under these circumstances. Moreover, the existing system is very versatile and could be complemented with other hydrogen production ones (using photovoltaic energy for example), or else two systems could be used in parallel if outputs up to 4 kW were required, and other applications in other markets, such as telecommunications or tele-metering systems, could be undertaken.

    The deployment of a market for hydrogen energy is a new problem, considered by governments, industrialists and scientists to meet global targets of greenhouse gases emissions reduction and to ensure security in energy supply. In this context, the optimization problem of scheduling the deployment until 2050 of the hydrogen supply chain for fuel market throughout a country has been the object of our study. We get support of Air Liquide Company, his experience and experts in production and distribution of industrial hydrogen, to build an approach to the problem meeting the requirements of an industrial context. After defining and characterizing the optimization problem through a systemic analysis of the distribution infrastructure, we proposed a method suited to its resolution. Monte Carlo simulations enabled us to develop cost functions. Then we developed a heuristic algorithm for approximate optimization of these cost functions. Our approach has necessitated the definition of simulation rules, a design of experiment and a regression method, as well as a heuristic algorithm adapted to the structure of the problem. The specification, development and use of software tools have helped to validate the chosen methodology for the optimization of the uncertain problem of our study. The scenario of evolution has created a reference to validate the model and provide some analysis for early studies of deployment. (author)

    In this study, we evaluated the impacts of producing HOF with a RON of 100, using a range of ethanol blending levels (E10, E25, and E40), vehicle efficiency gains, and HOF market penetration scenarios (3.4% to 70%), on WTW petroleum use and GHG emissions. In particular, we conducted LP modeling of petroleum refineries to examine the impacts of different HOF production scenarios on petroleum refining energy use and GHG emissions. We compared two cases of HOF vehicle fuel economy gains of 5% and 10% in terms of MPGGE to baseline regular gasoline vehicles. We incorporated three key factors in GREET — (1) refining energy intensities of gasoline components for the various ethanol blending options and market shares, (2) vehicle efficiency gains, and (3) upstream energy use and emissions associated with the production of different crude types and ethanol — to compare the WTW GHG emissions of various HOF/vehicle scenarios with the business-as-usual baseline regular gasoline (87 AKI E10) pathway.

    Full Text Available Context: This study presents the estimation of the evaporative emissions generated in the fuel distribution plant in El Alto de Ochomogo, Cartago, Costa Rica and the selection of the adequate recovery system to reduce the emission of these gases into the atmosphere, thus decreasing the adverse effects caused by these compounds in the environment and the health of nearby populations. Method: The fugitive emission rate estimated in the tanker vehicle loading process, using load loss emission factors, and fuel storage, through specialized software. Subsequently, we proceeded to make the selection of the appropriate treatment system, considering the flow capacity of the gaseous current that each technology can treat. Results: It was determined that the generation of VOCs is greater in the loading area than in the storage tanks, since they correspond to 95% and 5% respectively. Due to this, the proposal of the vapor treatment system focuses on the fuel-loading zone, selecting the cryogenic condensation as non-destructive recovery treatment. Conclusions: The estimation of the fugitive emission rate allowed to have a base to establish a strategy for the reduction of these emissions in favor of the health of the workers who are constantly exposed to them. To reduce direct emissions to the atmosphere during the loading of tanks. Necessary changes must be made to adapt them to an airtight system. That allows sending gasoline vapors that generated by the presence of residual product on the walls of trucks and due to the turbulence that arises during the loading of the new product, to the vapor recovery unit.

    The topic synthetic biology appears still as an 'empty basket to be filled'. However, there is already plenty of claims and visions, as well as convincing research strategies about the theme of synthetic biology. First of all, synthetic biology seems to be about the engineering of biology - about bottom-up and top-down approaches, compromising complexity versus stability of artificial architectures, relevant in biology. Synthetic biology accounts for heterogeneous approaches towards minimal and even artificial life, the engineering of biochemical pathways on the organismic level, the modelling of molecular processes and finally, the combination of synthetic with nature-derived materials and architectural concepts, such as a cellular membrane. Still, synthetic biology is a discipline, which embraces interdisciplinary attempts in order to have a profound, scientific base to enable the re-design of nature and to compose architectures and processes with man-made matter. We like to give an overview about the developments in the field of synthetic biology, regarding polymer-based analogs of cellular membranes and what questions can be answered by applying synthetic polymer science towards the smallest unit in life, namely a cell.

    Full Text Available Society is on the cusp of harnessing recent advances in synthetic biology to discover new bio-based products and routes to their affordable and sustainable manufacture. This is no more evident than in the discovery and manufacture of Synthetic Biological Materials, where synthetic biology has the capacity to usher in a new Materials from Biology era that will revolutionise the discovery and manufacture of innovative synthetic biological materials. These will encompass novel, smart, functionalised and hybrid materials for diverse applications whose discovery and routes to bio-production will be stimulated by the fusion of new technologies positioned across physical, digital and biological spheres. This article, which developed from an international workshop held in Manchester, United Kingdom, in 2017 [1], sets out to identify opportunities in the new materials from biology era. It considers requirements, early understanding and foresight of the challenges faced in delivering a Discovery to Manufacturing Pipeline for synthetic biological materials using synthetic biology approaches. This challenge spans the complete production cycle from intelligent and predictive design, fabrication, evaluation and production of synthetic biological materials to new ways of bringing these products to market. Pathway opportunities are identified that will help foster expertise sharing and infrastructure development to accelerate the delivery of a new generation of synthetic biological materials and the leveraging of existing investments in synthetic biology and advanced materials research to achieve this goal.

    Synthetic biology is an effort to make genetic engineering more useful by standardizing sections of genetic code. By standardizing genetic components, biological engineering will become much more similar to traditional fields of engineering, in which well-defined components and subsystems are readily available in markets. Specifications of the behavior of those components and subsystems can be used to model a system which incorporates them. Then, the behavior of the novel system can be simulated and optimized. Finally, the components and subsystems can be purchased and assembled to create the optimized system, which most often will exhibit behavior similar to that indicated by the model. The Space Synthetic Biology project began in 2012 as a multi-Center effort. The purpose of this project was to harness Synthetic Biology principals to enable NASA's missions. A central target for application was to Environmental Control & Life Support (ECLS). Engineers from NASA Marshall Space Flight Center's (MSFC's) ECLS Systems Development Branch (ES62) were brought into the project to contribute expertise in operational ECLS systems. Project lead scientists chose to pursue the development of bioelectrochemical technologies to spacecraft life support. Therefore, the ECLS element of the project became essentially an effort to develop a bioelectrochemical ECLS subsystem. Bioelectrochemical systems exploit the ability of many microorganisms to drive their metabolisms by direct or indirect utilization of electrical potential gradients. Whereas many microorganisms are capable of deriving the energy required for the processes of interest (such as carbon dioxide (CO2) fixation) from sunlight, it is believed that subsystems utilizing electrotrophs will exhibit smaller mass, volume, and power requirements than those that derive their energy from sunlight. In the first 2 years of the project, MSFC personnel conducted modeling, simulation, and conceptual design efforts to assist the

    This activity was begun with the assembly of information from Parsons' files and from contacts in the development and commercial fields. A further more extensive literature search was carried out using the Energy Data Base and the American Petroleum Institute Data Base. These are part of the DOE/RECON system. Approximately 6000 references and abstracts were obtained from the EDB search. These were reviewed and the especially pertinent documents, approximately 300, were acquired in the form of paper copy or microfiche. A Fuel Properties form was developed for listing information pertinent to gas turbine liquid fuel properties specifications. Fuel properties data for liquid fuels from selected synfuel processes, deemed to be successful candidates for near future commercial plants were tabulated on the forms. The processes selected consisted of H-Coal, SRC-II and Exxon Donor Solvent (EDS) coal liquefaction processes plus Paraho and Tosco shale oil processes. Fuel properties analyses for crude and distillate syncrude process products are contained in Section 2. Analyses representing synthetic fuels given refinery treatments, mostly bench scale hydrotreating, are contained in Section 3. Section 4 discusses gas turbine fuel specifications based on petroleum source fuels as developed by the major gas turbine manufacturers. Section 5 presents the on-site gas turbine fuel treatments applicable to petroleum base fuels impurities content in order to prevent adverse contaminant effects. Section 7 relates the environmental aspects of gas turbine fuel usage and combustion performance. It appears that the near future stationary industrial gas turbine fuel market will require that some of the synthetic fuels be refined to the point that they resemble petroleum based fuels.

    Development of synthetic carbonaceous fuels and feedstocks (SCFF) is imperative if the U.S. is to maintain its world leadership. All forms of carbonaceous materials can serve as sources of raw material for SCFF, however, here we consider the ultimate renewable resource of carbon which is CO/sub 2/ from the atmosphere or the oceans. A number of methods for the recovery of CO/sub 2/ have been examined. An absorption-stripping system utilizing dilute carbonate solvent appears most economical for atmospheric recovery while distillation appears of interest for sea-water recovery. An alternative isothermal process utilizing chlor-alkali cells is also described. Electrolytic hydrogen is thermocatalytically combined with the CO/sub 2/ to form methanol which can then be dehydrated to gasoline. Production cost is dominated by the energy for hydrogen and the plant capital investment. Base loaded nuclear power plants supplying peaking load and generating SCFF in an off-peak mode is proposed for reducing costs. Under 1974/5 conditions, incremental power costs would have been a minimum. Under 1985 escalated conditions, incremental costs indicate 6 mills/kWh(e) for power which yields 33.9 c/gallon methanol or 77.1 c/gallon of equivalent gasoline which takes credit for oxygen would break even with $23/bbl of oil. The capital investment for producing the equivalent of one million barrels/day of gasoline in 142 nuclear reactors of 100 MW(e) capacity, operating in an off-peak mode, amounts to slightly more than the investment in new oil exploration and production facilities and considerably less than the projected outflow of capital to foreign OPEC countries. The nuclear synthesis-route using atmospheric and aquatic CO/sub 2/ simulates the solar photosynthetic process and provides a long-term renewable and environmentally acceptable alternate source of SCFF.

This emerging field should play an important role in future agriculture for traditional crop improvement, but also in enabling novel bioproduction in plants. In this review we discuss the design cycles of synthetic biology as well as key engineering principles, genetic parts, and computational tools that can be utilized in plant synthetic biology. Some pioneering examples are offered as a demonstration of how synthetic biology can be used to modify plants for specific purposes. These include synthetic sensors, synthetic metabolic pathways, and synthetic genomes. We also speculate about the future of synthetic biology of plants. Copyright © 2015 Elsevier Ltd.

    Full Text Available In Ireland, truck transport by road dominates and will remain the main transportation mode of biomass. Cost efficiency and flexibility of forest transport can be typically improved by optimising routes. It is important to know every process and attributes within the workflow of roundwood transport. This study aimed to analyse characteristics of timber trucking in Ireland, and to estimate the least-cost route for the distribution of biomass with the use of geographic information systems (GIS. Firstly, a tracking system that recorded the truck’s movements and fuel consumption was installed. A total of 152 trips were recorded, routes were chosen by the truck driver. The recorded information was used to analyse the distances and times travelled loaded and unloaded per road class, breaks, loading and unloading times as well as fuel consumption. Secondly, the routes taken by the truck where compared with routes created using Network Analyst (NA, an extension of ArcGIS. Four scenarios based on route selection criteria were selected: shortest distance (S1, shorted time (S2, and prioritising high-class roads with shortest distance (S3 and time (S4. Results from the analysis of the tracking system data showed that driving both loaded and unloaded occupied on average 69% of the driver’s working shift; with an average time driving loaded of 49%. The travel distance per trip varied from 112 km and 197 km, with the truck driver using mostly national and regional roads. An average 2% of the total distance and 11% of the total time was spent driving on forest roads. In general, the truck’s speed recorded on the different road classes was on average 30% lower than the legal maximum speed. The average fuel consumption was 0.64 L/km. In terms of the route comparison, the driving directions from the truck routes coincided with 77% of the directions of the routes based on shortest driving time (S2 and S4. All the routes chosen by the driver had 22% longer

    Decision-making in electricity markets is complicated by uncertainties in demand growth, power supplies and fuel prices. In Peru, where the electrical power system is highly dependent on water resources at dams and river flows, hydrological uncertainties play a primary role in planning, price and dispatch forecast. This paper proposed a signal processing method for generating new synthetic river flow time series as a support for planning and spot market price forecasting. River flow time series are natural phenomena representing a continuous-time domain process. As an alternative synthetic representation of the original river flow time series, this proposed signal processing method preserves correlations, basic statistics and seasonality. It takes into account deterministic, periodic and non periodic components such as those due to the El Nino Southern Oscillation phenomenon. The new synthetic time series has many correlations with the original river flow time series, rendering it suitable for possible replacement of the classical method of sorting historical river flow time series. As a dispatch and planning approach to spot pricing, the proposed method offers higher accuracy modeling by decomposing the signal into deterministic, periodic, non periodic and stochastic sub signals. 4 refs., 4 tabs., 13 figs

    The objective of this paper is to discuss the possible impacts on the Brazilian economy of an oil shortage crisis and its effects on the domestic market for liquid fuels. The results were obtained from simulations using a multi-sector general equilibrium model. The scenarios used in the numerical experiments were characterized by different constraining levels in imports of crude oil and oil products and also by the ability gasoline may be substituted by fuel ethanol. It is shown that the economic effects depend to a large degree on the substitution flexibility between liquid fuels. Thus it is expected that the introduction of flex-fuel vehicles in the light-duty fleet will make the Brazilian economy much less vulnerable in the event of an external oil-supply shock. (author)

    Society is on the cusp of harnessing recent advances in synthetic biology to discover new bio-based products and routes to their affordable and sustainable manufacture. This is no more evident than in the discovery and manufacture of Synthetic Biological Materials , where synthetic biology has the capacity to usher in a new Materials from Biology era that will revolutionise the discovery and manufacture of innovative synthetic biological materials. These will encompass novel, smart, functionalised and hybrid materials for diverse applications whose discovery and routes to bio-production will be stimulated by the fusion of new technologies positioned across physical, digital and biological spheres. This article, which developed from an international workshop held in Manchester, United Kingdom, in 2017 [1], sets out to identify opportunities in the new materials from biology era. It considers requirements, early understanding and foresight of the challenges faced in delivering a Discovery to Manufacturing Pipeline for synthetic biological materials using synthetic biology approaches. This challenge spans the complete production cycle from intelligent and predictive design, fabrication, evaluation and production of synthetic biological materials to new ways of bringing these products to market. Pathway opportunities are identified that will help foster expertise sharing and infrastructure development to accelerate the delivery of a new generation of synthetic biological materials and the leveraging of existing investments in synthetic biology and advanced materials research to achieve this goal.

  10. Consumer preference and willingness to pay for a renewable fuel standard (RFS) policy: Focusing on ex-ante market analysis and segmentation

    Total energy consumption of oil in 2050 is expected to increase to 1.6 times its level in 2005, and greenhouse gas (GHG) emissions in the transportation sector will be second only to the electricity sector. In order to reduce GHG emissions in transportation, leading countries have started to implement renewable fuel standard (RFS) policies. Other countries such as Korea have recently started implementing RFS policies in order to comply with the proposed global GHG reduction target. However, previous research did not consider the impact of RFS policy on consumer acceptance levels. Therefore, this study analyzes consumer preferences and willingness-to-pay (WTP) for RFS. To provide detailed policy strategies, this study conducts additional analysis using market segmentation and sensitivity analysis. The results indicate that consumers generally accept the cost of implementing an RFS policy if the cost falls between KRW 101.78/liter (USD 0.33/gal) and KRW 187.26/liter (USD 0.60/gal). In addition, consumer WTP for implementing an RFS policy changes when the income exceeds KRW 5 million (USD 4229.1) in driver group, and relatively lower-income groups tend not to support RFS policies. Based on the results of this study, we can suggest proper pricing policies for each income group and a public relations strategy to improve the level of policy acceptance. - Highlights: • We analyze consumer preferences and willingness-to-pay for Korea's RFS policy. • We also conduct market segmentation and sensitivity analysis. • Korean consumers will accept the cost between KRW 101.78/liter and KRW 187.26/liter. • Preference structure for RFS policy is changed when income exceeds KRW 5 million. • Relatively lower-income groups tend not to support RFS policies.

    Methoxphenidine (MXP) was one of several NMDA antagonists marketed in 2013 to replace the recently controlled compound Methoxetamine (MXE). A steep rise in user interest was recorded, despite vendor cautioning of limited user feedback. The study presented a phenomenological analysis of MXP experiences amongst recreational drug users as posted on public Internet fora. Internet searches were carried out using specific key words; "methoxphenidine," "MXP" and in combination with "experience," "report," "forum," and "trip." Seven self-reported experiences and 28 thread discussions relating sole use of MXP were analyzed using the Empirical Phenomenological Psychological method. Five themes and 61 categories emerged. MXP is marketed as a legal replacement for MXE, diphenidine, and ketamine, with a dissociative and stimulant wave outcome often lasting for days. Harm reduction tactics, awareness of prior tolerance to dissociative and optimal settings for use are discussed. Acute side-effects relate to hypertension and seizures. Chronic long-term memory loss and limb numbness is reported. Sense of empowerment occurs in the afterglow experience. Internet drug fora fuel information exchange and informed consumerism of synthetic compounds, and offer viable mechanisms for pre- and post-purchase decision making and indigenous harm reduction. Continued surveillance of synthetic market entries and user trends is warranted.

  13. Analysis of the market for diesel PEM fuel cell auxiliary power units onboard long-haul trucks and of its implications for the large-scale adoption of PEM FCs

    2010-01-01

    Proton exchange membrane fuel cells (PEM FCs) offer a promising alternative to internal combustion engines in road transport. During the last decade PEM FC research, development and demonstration (RD and D) activities have been steadily increasing worldwide, and targets have been set to begin their commercialisation in road transport by 2015-2020. However, there still is considerable uncertainty on whether these targets will actually be met. The picture is complex and market and technology issues are closely interlinked; investment in RD and D projects is essential but not sufficient; the development of suitable early markets is also necessary and policy is set to play an important role. Auxiliary power units (APUs) are generally regarded as one important early market for FCs in transport. This paper analyses the possible future market for diesel PEM FC APUs onboard long-haul trucks and its implications for the development of PEM FCs in general. The analysis, part of the project HyTRAN (EC Contract no. 502577), is aided by the use of a dynamic simulation model of technology and markets developed by the author. Results suggest that an interesting window of opportunity for diesel PEM FC APUs exists but this is subject to additional research particularly targeted at the rapid development of fuel processors.

    The increase in production of heavier oils and the recent changes in the demand for petroleum derivatives requires modifications in refining schemes of Brazilian refineries, which were originally projected for processing light oils and production of mainly gasoline by fluid catalytic cracking units. This is necessary because forecasts indicate a larger increase in demand for diesel oil instead of gasoline. These same forecasts reveal an expressive reduction in the demand for fuel oil, which still is produced in large amounts in Brazilian refineries due to the quality of the oils from local fields that are processed. The current challenge for the local oil industry is to adapt the present refineries to produce more valuable derivatives from heavy oils. For this purpose, PETROBRAS is investing in the construction of conversion units with technology for processing heavier feeds, especially in the Delayed Coking process. This work has as an objective to identify the importance of the delayed coke units in the current scenario of the oil industry, highlighting the main investments in construction of new units and evaluating the impact of the existing units on the market for petroleum derivatives.

    In this paper, we propose an historical survey of the expression "synthetic biology" in order to identify its main philosophical components. The result of the analysis is then used to investigate the meaning of the notion of "synthetic man". It is shown that both notions share a common philosophical background that can be summed up by the short but meaningful assertion: "biology is technology". The analysis allows us to distinguish two notions that are often confused in transhumanist literature: the notion of synthetic man and the notion of renewed man. The consequences of this crucial distinction are discussed. Copyright © 2015 Académie des sciences. Published by Elsevier SAS. All rights reserved.

  17. Market possibilities for biofuels

    1992-01-01

    The market for biofuels in Sweden after introduction of a proposed CO 2 -tax on fossil fuels is forecast. The competition between biofuels, fossil fuels and electricity is described for important market segments such as: Paper industry, Sawmills, Other energy-intensive industry, Power and heat producers, small Heat producers, and for Space heating of one-family houses. A market increase of the use of biofuels is probable for the segment small (district) heating centrals, 10 TWh in the next ten year period and even more during a longer period. Other market segments will not be much affected. An increased use of biofuels in paper and pulp industry will not influence the fuel market, since the increase will happen in the industry's normal lumber purchase. (2 figs., 18 tabs.)

    The niche or early entry market penetration by ONSI and its phosphoric acid fuel cell technology has proven that fuel cells are reliable and suitable for premium power and other opportunity fuel niche market applications. Now, new fuel cell technologies - solid oxide fuel cells, molten carbonate fuel cells, and polymer electrolyte fuel cells - are being developed for near-term distributed generation shortly after 2003. Some of the evolving fuel cell systems are incorporating gas turbines in hybrid configurations. The combination of the gas turbine with the fuel cell promises to lower system costs and increase efficiency to enhance market penetration. Market estimates indicate that significant early entry markets exist to sustain the initially high cost of some distributed generation technologies. However, distributed generation technologies must have low introductory first cost, low installation cost, and high system reliability to be viable options in competitive commercial and industrial markets. In the long-term, solid state fuel cell technology with stack costs under $100/kilowatt (kW) promises deeper and wider market penetration in a range of applications including a residential, auxillary power, and the mature distributed generation markets. The solid state energy conversion alliance (SECA) with its vision for fuel cells in 2010 was recently formed to commercialize solid state fuel cells and realize the full potential of the fuel cell technology. Ultimately, the SECA concept could lead to megawatt-size fuel-cell systems for commercial and industrial applications and Vision 21 fuel cell turbine hybrid energy plants in 2015. (orig.)

    In 2002, 65 per cent of supply from the Western Canadian Sedimentary Basin (WCSB) was shipped by Enbridge to North American markets. A survey of refineries is used by Enbridge to establish expected market demand for oil from the WCSB. An Oil Sands Markets Study was undertaken to provide answers to the following: (1) what volumes to which markets will maximize the value of WCSB production? (2) what mix of raw bitumen, synthetic and fully saturated synthetic best fits the available markets? and (3) what infrastructure expansions, extensions, conversions and new development will be required? Enbridge elected to use the North American petroleum model using Alto's MarketPoint system. It was adapted to evaluate crude oil and refined products. It is expected that by the end of the first quarter of 2003, the preliminary results will be available for review with industry. There are currently 20 crude types identified as available to refineries. All imported crude types will be included. Eight distinct classes of refined products were used: liquid propane gas (LPG), low and high sulphur gasoline, jet fuel, low and high sulphur distillate, asphalt and coke. All major conversion units were modeled for all 150 refineries in Canada and the United States. figs

    Synthetic defects are an important tool used for characterizing the performance of nondestructive evaluation techniques. Viscous material-filled synthetic defects were developed for use in vibrothermography (also known as sonic IR) as a tool to improve inspection accuracy and reliability. This paper describes how the heat-generation response of these VMF synthetic defects is similar to the response of real defects. It also shows how VMF defects can be applied to improve inspection accuracy for complex industrial parts and presents a study of their application in an aircraft engine stator vane.

    Despite their obvious relationship and overlap, the field of physics is blessed with many insightful laws, while such laws are sadly absent in biology. Here we aim to discuss how the rise of a more recent field known as synthetic biology may allow us to more directly test hypotheses regarding the possible design principles of natural biological networks and systems. In particular, this review focuses on synthetic gene regulatory networks engineered to perform specific functions or exhibit particular dynamic behaviors. Advances in synthetic biology may set the stage to uncover the relationship of potential biological principles to those developed in physics. (review article)

  11. Commercializing fuel cells: managing risks

    Science.gov (United States)

    Bos, Peter B.

    Commercialization of fuel cells, like any other product, entails both financial and technical risks. Most of the fuel cell literature has focussed upon technical risks, however, the most significant risks during commercialization may well be associated with the financial funding requirements of this process. Successful commercialization requires an integrated management of these risks. Like any developing technology, fuel cells face the typical 'Catch-22' of commercialization: "to enter the market, the production costs must come down, however, to lower these costs, the cumulative production must be greatly increased, i.e. significant market penetration must occur". Unless explicit steps are taken to address this dilemma, fuel cell commercialization will remain slow and require large subsidies for market entry. To successfully address this commercialization dilemma, it is necessary to follow a market-driven commercialization strategy that identifies high-value entry markets while minimizing the financial and technical risks of market entry. The financial and technical risks of fuel cell commercialization are minimized, both for vendors and end-users, with the initial market entry of small-scale systems into high-value stationary applications. Small-scale systems, in the order of 1-40 kW, benefit from economies of production — as opposed to economies to scale — to attain rapid cost reductions from production learning and continuous technological innovation. These capital costs reductions will accelerate their commercialization through market pull as the fuel cell systems become progressively more viable, starting with various high-value stationary and, eventually, for high-volume mobile applications. To facilitate market penetration via market pull, fuel cell systems must meet market-derived economic and technical specifications and be compatible with existing market and fuels infrastructures. Compatibility with the fuels infrastructure is facilitated by a

    Synthetic biological engineering is emerging from biology as a distinct discipline based on quantification. The technologies propelling synthetic biology are not new, nor is the concept of designing novel biological molecules. What is new is the emphasis on system behavior. The objective is the design and construction of new biological devices and systems to deliver useful applications. Numerous synthetic gene circuits have been created in the past decade, including bistable switches, oscillators, and logic gates, and possible applications abound, including biofuels, detectors for biochemical and chemical weapons, disease diagnosis, and gene therapies. More than fifty years after the discovery of the molecular structure of DNA, molecular biology is mature enough for real quantification that is useful for biological engineering applications, similar to the revolution in modeling in chemistry in the 1950s. With the excitement that synthetic biology is generating, the engineering and biological science communities appear remarkably willing to cross disciplinary boundaries toward a common goal.

    2017-06-01

    This paper summarises the key findings and recommendations of a 3.5 year study into the research, development and demonstration priorities to establish a solar fuels industry in Australia. While Australia has one of the best solar resources in the world, it also has an abundance of conventional fuels such as coal and natural gas. The country is heavily dependent on fossil fuels for its primary energy supply and international trade, and is seeking pathways to reduce emissions intensity. While renewable electricity will be able to displace fossil fuels in the electricity sector, this only addresses about 16% of energy consumption by end use. Concentrating solar fuels (CSF) are produced either in full or in part from concentrated solar energy, and can provide either complete or partial reduction of the CO2 emissions associated with energy consumption. Our study reviewed the various potential solar thermal technology pathways and feedstocks available to produce a range of CSF products such as hydrogen, ammonia, methanol and synthetic gasoline or diesel. We conducted what we believe to be the broadest and most sophisticated evaluation of the many options to identify those that are most prospective, including an evaluation of the expected final fuel costs. The study identified the following opportunities for CSF: • Australia: substitution of imported liquid fuels (gasoline and diesel) with synthetic CSF options would provide fuel security through the utilization of domestic resources. Ammonia is also a potentially attractive CSF product as it is produced in large quantities for fertilisers and explosives. • Export markets: Australia has significant trading relationships with many Asian countries in the energy domain, and CSF fuels could provide a long term future to enable such relationships to continue - or grow - in a carbon constrained world. Japan in particular is considering how to transition to a hydrogen economy, and could be a customer for CSF hydrogen or

    The opportunities for fuel cell development are discussed. Fuel cells are highly efficient, reliable and require little maintenance. They also produce virtually zero emissions. The author stated that there are some complicated issues to resolve before fuel cells can be widely used. These include hydrogen availability and infrastructure. While the cost of fuel cells is currently very high, these costs are constantly coming down. The industry is still in the early stages of development. The driving forces for the development of fuel cells are: deregulation of energy markets, growing expectations for distributed power generation, discontinuity between energy supply and demand, and environmental concerns. 12 figs.

    In South Africa, a country that is rich in natural resources, gross domestic product has risen steadily since the historic elections in April 1994. In 1995, foreign trade made up almost 50 per cent of the country's gross national product. Unemployment and concurrent shortage of skilled labour are some of the major challenges that still exist for South Africa. Sasol is one of South Africa's top 10 private companies. It was founded in 1950; it supplies 44 per cent of South Africa's liquid fuel needs and produces most of the feedstocks used by the chemical and plastics industries in the country. The company is known for innovative technologies, such as the Sasol Synthol Process. It produces high-quality synthetic fuels such as petrol, diesel, kerosene, gas and furnace oils. The unique Sasol Synthol Process was described. Coal is put under high pressure and high temperature in the presence of steam and oxygen, is converted to crude gas, purified by removing sulfur and is then used in the production of gasoline, diesel and other fuels. The process also yields 120 other chemical products for domestic and international markets. 3 refs., 5 figs

    2014-01-01

    The Next Generation Nuclear Plant (NGNP) Industry Alliance (NIA) consists of 16 companies and organizations that support development and deployment of modular High Temperature Gas-Cooled Reactors (modular HTGRs or MHRs). These companies include reactor vendors, utilities, potential industrial end users of MHR process steam/heat, nuclear graphite vendors, and companies with design, technology development, regulatory licensing, and other HTGR subject matter expertise. The NIA has been investigating potential markets for MHRs in both North America and globally as part of its business plan development. MHRs have inherent, melt-down proof safety with high-temperature capability and high utilization of the nuclear heat for production of electricity and process heat. These features allow MHRs to be located within close proximity to the public and industrial end users, and in locations with very limited or no availability of cooling water as the ultimate heat sink. This paper provides a summary of recent NIA target market assessments, including selected markets which currently utilize high value oil and expensive liquefied natural gas (LNG) fuels for process heat and electricity generation on a large scale (e.g., Kingdom of Saudi Arabia, Japan, and Korea). Results show that significant markets exist today for economical deployment of steam-cycle MHRs for electricity and process heat, especially in countries/regions that utilize expensive (or heavily subsidized) fossil fuels for energy needs. Low natural gas prices in North America presently inhibit expansion of any nuclear technology, but MHRs should be economically competitive by the 2030 - 2040 time frame, when natural gas prices are projected to be in the $7 to $10 per MMBtu price range. There is also good market potential for higher temperature MHR applications, including nuclear steel manufacturing, production of synthetic fuels, and hydrogen production. (author)

These companies include reactor vendors, utilities, potential industrial end users of MHR process steam/heat, nuclear graphite vendors, and companies with design, technology development, regulatory licensing, and other HTGR subject matter expertise. The NIA has been investigating potential markets for MHRs in both North America and globally as part of its business plan development. MHRs have inherent, melt-down proof safety with high-temperature capability and high utilization of the nuclear heat for production of electricity and process heat. These features allow MHRs to be located within close proximity to the public and industrial end users, and in locations with very limited or no availability of cooling water as the ultimate heat sink. This paper provides a summary of recent NIA target market assessments, including selected markets which currently utilize high value oil and expensive liquefied natural gas (LNG) fuels for process heat and electricity generation on a large scale (e.g., Kingdom of Saudi Arabia, Japan, and Korea). Results show that significant markets exist today for economical deployment of steam-cycle MHRs for electricity and process heat, especially in countries/regions that utilize expensive (or heavily subsidized) fossil fuels for energy needs. Low natural gas prices in North America presently inhibit expansion of any nuclear technology, but MHRs should be economically competitive by the 2030 - 2040 time frame, when natural gas prices are projected to be in the $7 to $10 per MMBtu price range. There is also good market potential for higher temperature MHR applications, including nuclear steel manufacturing, production of synthetic fuels, and hydrogen production. (author)

    The risks of maintaining current CO2 emission trends have led to interest in producing biofuels using engineered microbes. Microbial biofuels reduce emissions because CO2 produced by fuel combustion is offset by CO2 captured by growing biomass, which is later used as feedstock for biofuel fermentation. Hydrocarbons found in petroleum fuels share striking similarity with biological lipids. Here we review synthetic metabolic pathways based on fatty acid and isoprenoid metabolism to produce alkanes and other molecules suitable as biofuels. We further discuss engineering strategies to optimize engineered biosynthetic routes, as well as the potential of synthetic biology for sustainable manufacturing. Published by Elsevier Ltd.

    What implications might synthetic biology's potential as a wholly new method of production have for the world economy, particularly developing countries? Theories of political economy predict that synthetic biology can shift terms of trade and displace producers in developing countries. Governments, however, retain the ability to mitigate negative changes through social safety nets and to foster adaptation to some changes through research, education and investment. We consider the effects the synthetic production of otherwise naturally derived molecules are likely to have on trade and investment, particularly in developing countries. Both rubber in Malaysia and indigo dyes in India provide historical examples of natural molecules that faced market dislocations from synthetic competitors. Natural rubber was able to maintain significant market share, while natural indigo vanished from world markets. These cases demonstrate the two extremes of the impact synthetic biology might have on naturally derived products. If developing countries can cushion the pain of technological changes by providing producers support as they retool or exit, the harmful effects of synthetic biology can be mitigated while its benefits can still be captured.

  7. Alternate Fuels for Use in Commercial Aircraft

    2008-01-01

    The engine and aircraft Research and Development (R&D) communities have been investigating alternative fueling in near-term, midterm, and far-term aircraft. A drop in jet fuel replacement, consisting of a kerosene (Jet-A) and synthetic fuel blend, will be possible for use in existing and near-term aircraft. Future midterm aircraft may use a biojet and synthetic fuel blend in ultra-efficient airplane designs. Future far-term engines and aircraft in 50-plus years may be specifically designed to use a low- or zero-carbon fuel. Synthetic jet fuels from coal, natural gas, or other hydrocarbon feedstocks are very similar in performance to conventional jet fuel, yet the additional CO2 produced during the manufacturing needs to be permanently sequestered. Biojet fuels need to be developed specifically for jet aircraft without displacing food production. Envisioned as midterm aircraft fuel, if the performance and cost liabilities can be overcome, biofuel blends with synthetic jet or Jet-A fuels have near-term potential in terms of global climatic concerns. Long-term solutions address dramatic emissions reductions through use of alternate aircraft fuels such as liquid hydrogen or liquid methane. Either of these new aircraft fuels will require an enormous change in infrastructure and thus engine and airplane design. Life-cycle environmental questions need to be addressed.

    Nuclear fuel supply is viewed as a buyer's market of assured medium-term stability. Even on a long-term basis, no shortage is envisaged for all conceivable expansion schedules. The conversion and enrichment facilities developed since the mid-seventies have done much to stabilize the market, owing to the fact that one-sided political decisions by the USA can be counteracted efficiently. In view of the uncertainties concerning realistic nuclear waste management strategies, thermal recycling and mixed oxide fuel elements might increase their market share in the future. Capacities are being planned accordingly. (orig.) [de

    The Alberta Chamber of Resources programs and initiatives on oil sands and heavy oil, and strategies for revitalizing oilsands development in Alberta are described. The regional upgrader and satellite production facilities concept, and technology requirements for mineable oil sands by the year 2010 are discussed. Strategic alliances in furtherence of oil sands research and development and the National Task Force on Oil Sands Strategies are described. Changes in requirements for transportation fuels due to stricter regulations and environmental initiatives will cause a trend to lighter fuels with more hydrogen content, less aromatics, nitrogen, sulfur and metals. A preferred refinery configuration will be able to process heavier crudes and synthetic crudes, have no heavy fuel oil product, low sulfur products, low aromatics with high octane, and low operating cost. A regional or central facility that combines the processing capabilities of a bitumen upgrader with the process units of a refinery is preferred. Advantages of this concept are: value addition to the feedstock is maximized; dependence on refineries is eliminated; restriction on synthetic crude oil volumes due to capacity limitations at refineries is eliminated; directly marketable finished products are produced; more stringent quality specifications are satisfied; and the synergies between upgrading and refining improve overall economics of processing. It is recommended that the concept of regional upgraders be adopted for Alberta, strategic alliances be encouraged, incentives for bitumen production be provided, and a bitumen pipeline network be developed. 12 refs

    A desired architecture for long duration spaceflight, like aboard the International Space Station or for future missions to Mars, is to provide a supply of fresh food crops for the astronauts. However, some crops can create a high proportion of inedible plant waste. The main goal of the Synthetic Biology project, Cow in a Column, was to produce the components of milk (sugar, lipid, protein) from inedible plant waste by utilizing microorganisms (fungi, yeast, bacteria). Of particular interest was utilizing the valuable polysaccharide, cellulose, found in plant waste, to naturally fuel-through microorganism cellular metabolism- the creation of sugar (glucose), lipid (milk fat), and protein (casein) in order to produce a synthetic edible food product. Environmental conditions such as pH, temperature, carbon source, aeration, and choice microorganisms were optimized in the laboratory and the desired end-products, sugars and lipids, were analyzed. Trichoderma reesei, a known cellulolytic fungus, was utilized to drive the production of glucose, with the intent that the produced glucose would serve as the carbon source for milk fat production and be a substitute for the milk sugar lactose. Lipid production would be carried out by Rhodosporidium toruloides, yeast known to accumulate those lipids that are typically found in milk fat. Results showed that glucose and total lipid content were below what was expected during this phase of experimentation. In addition, individual analysis of six fatty acids revealed that the percentage of each fatty acid was lower than naturally produced bovine milk. Overall, this research indicates that microorganisms could be utilized to breakdown inedible solid waste to produce useable products. For future work, the production of the casein protein for milk would require the development of a genetically modified organism, which was beyond the scope of the original project. Additional trials would be needed to further refine the required

    Full Text Available The evolution of eukaryotic cells is widely agreed to have proceeded through a series of endosymbiotic events between larger cells and proteobacteria or cyanobacteria, leading to the formation of mitochondria or chloroplasts, respectively. Engineered endosymbiotic relationships between different species of cells are a valuable tool for synthetic biology, where engineered pathways based on two species could take advantage of the unique abilities of each mutualistic partner.We explored the possibility of using the photosynthetic bacterium Synechococcus elongatus PCC 7942 as a platform for studying evolutionary dynamics and for designing two-species synthetic biological systems. We observed that the cyanobacteria were relatively harmless to eukaryotic host cells compared to Escherichia coli when injected into the embryos of zebrafish, Danio rerio, or taken up by mammalian macrophages. In addition, when engineered with invasin from Yersinia pestis and listeriolysin O from Listeria monocytogenes, S. elongatus was able to invade cultured mammalian cells and divide inside macrophages.Our results show that it is possible to engineer photosynthetic bacteria to invade the cytoplasm of mammalian cells for further engineering and applications in synthetic biology. Engineered invasive but non-pathogenic or immunogenic photosynthetic bacteria have great potential as synthetic biological devices.

  19. Evidence of fueling of the 2000 new economy bubble by foreign capital inflow: implications for the future of the US economy and its stock market

    Science.gov (United States)

    Sornette, Didier; Zhou, Wei-Xing

    2004-02-01

    Previous analyses of a large ensemble of stock markets have demonstrated that a log-periodic power law (LPPL) behavior of the prices constitutes a qualifying signature of speculative bubbles that often land with a crash. We detect such a LPPL signature in the foreign capital inflow during the bubble on the US markets culminating in March 2000. We detect a weak synchronization and lag with the NASDAQ LPPL pattern. We propose to rationalize these observations by the existence of positive feedback loops between market-appreciation/increased-spending/increased-deficit-of-balance-of-payment/larger-foreign-surplus/increased-foreign-capital-inflows and so on. Our analysis suggests that foreign capital inflow has been following rather than causing the bubble. We then combine a macroeconomic analysis of feedback processes occurring between the economy and the stock market with a technical analysis of more than 200 years of the DJIA to investigate possible scenarios for the future, three years after the end of the bubble and deep into a bearish regime. We conclude that the low interest rates and depreciating dollar are the indispensable ingredients for a lower sustainable burden of the global US debt structure and for allowing the slow rebuilding of an internationally competitive economy. This will probably be accompanied by a weak stock market on the medium term as the growing Federal deficit is consuming a large part of the foreign surplus dollars and the stock market is remaining a very risky and unattractive investment. Notwithstanding strong surge of liquidity in recent months orchestrated by the Federal Reserve, this macroeconomic analysis which incorporates an element of collective behavior is in line with our recent analyses of the bearish market that started in 2000 in terms of a LPPL “anti-bubble”. We project this LPPL anti-bubble to continue at least for another year. On the short term, increased availability of liquidity (M1) and self-fulfilling bullish

    This article analyzes the ethics of synthetic biology (synbio) from a consequentialist perspective, examining potential effects on food and agriculture, and on medicine, fuel, and the advancement of science. The issues of biosafety and biosecurity are also examined. A consequentialist analysis offers an essential road map to policymakers and regulators as to how to deal with synbio. Additionally, the article discusses the limitations of consequentialism as a tool for analysing synbioethics. Is it possible to predict, with any degree of plausibility, what the consequences of synthetic biology will be in 50 years, or in 100, or in 500? Synbio may take humanity to a place of radical departure from what is known or knowable.

  2. Eastern Europe's market role

    Schreiber, K.F.

    1991-01-01

    Until the late 1980s, trade in nuclear fuel between market economy countries and those with planned economies was limited. The exception to this was in the enrichment market across Western Europe during the 1970s. Most of the nuclear generating plants in the Soviet Union and Eastern Europe are light water reactors needing enriched uranium. Under the fuel supply agreements with Eastern Europe, the Soviet Union has provided all of the regions' enrichment services, and therefore it has developed the only enrichment facilities. Techsnabexport (TENEX), the USSR foreign trade organization for the nuclear fuel cycle, first appeared in the early 1970s. It was as an alternative supplier to the US government, which had a monopoly in the West regarding enrichment. In 1986 the USSR entered and soon dominated the spot market for enrichment. Political changes in Eastern Europe at the end of 1989 and throughout 1990 opened the nuclear fuel market even wider. In 1990 the USSR began allowing exports of concentrates, as well as enriched product, and a free flow of trade to the Western market is now developing for both enrichment and uranium. (author)

    Energy Technology Data Exchange (ETDEWEB)

    2012-02-15

    Up until 2020 and onwards the analysis indicates that especially electricity, biogas and natural gas as propellants is economically attractive compared to conventional gasoline and diesel while other fuels have the same or higher costs for petrol and diesel. Especially biogas and electricity will also offer significant reductions in CO{sub 2} emissions, but also hydrogen, methanol, DME and to a lesser extent the second generation bioethanol and most of the other alternative fuels reduce CO{sub 2} emissions. Use of the traditional food-based first generation biofuels involves, at best, only modest climate benefits if land use changes are counted, and at worst, significant negative climate effects. Natural gas as a propellant involves a moderate climate gain, but may play a role for building infrastructure and market for gaseous fuels in large fleets, thereby contributing to the phasing in of biogas for transport. The electric-based automotive fuels are the most effective due to a high efficiency of the engine and an increasing proportion of wind energy in the electricity supply. The methanol track also has a relatively high efficiency. Among the others, the track based on diesel engines (biodiesel) is more effective than the track based on gasoline/Otto engines (gas and ethanol) as a result of the diesel engine's better efficiency. For the heavy vehicles all the selected alternative fuels to varying degrees reduce emissions of CO{sub 2}, particularly DME based on wood. The only exception to this is - as for passenger cars - the propellant synthetic diesel based on coal. (LN).

In the reviewed literature and authors own observations there have been discovered some cases of mental addiction development to synthetic cannabinoids. The analysis of new literature data and own clinical observations helped the authors to compare the psychotropic effects caused by this group of drugs, relative to other known surfactants. The toxic effects of CSC on the body greatly exceeds the use of plant cannabinoids, and it has almost the same effects as the synthetic cathinone’s. The speed of formation of psychological dependence is lower compared to synthetic cathinone. Developing current strategies for diagnosis, treatment, and rehabilitation of patients who use synthetic cannabinoids remains an important task for practical healthcare.

  13. Potential impact of environmental requirements on petroleum products derived from synthetic crude

    International Nuclear Information System (INIS)

    1997-01-01

    Fuel quality proposals regarding gasoline and diesel fuels were discussed. Strict regulations on air emissions will mean changes in transportation fuel specifications which will ultimately impact on the refining industry. As fuel quality requirements become more stringent, refiners will need to look more closely at increasing the use of Canadian synthetic crude as a refinery feed. The fuel quality specifications with the potentially highest impact for the continued use of synthetic crude are those relating to sulphur, aromatics (including benzene), and olefins in gasoline and sulphur, aromatics and cetane in diesel fuel. Synthetic crude has an advantage in terms of gasoline sulphur content. The FCC feed is at a low enough sulphur level to result in gasoline components that would allow refiners to meet final gasoline sulphur levels of less than 100 ppm. In either case, synthetic middle distillate must be upgraded. Options that face the synthetic crude and refining industries are: (1) synthetic crude producers may install the process equipment needed to upgrade the middle distillate portion of their synthetic crude stream, (2) refiners may install equipment to upgrade just the diesel fuel portion of the middle distillate pool and jet fuel, and (3) a joint effort may be made by the two industries. The National Centre for Upgrading Technology (NCUT) and the Western Research Centre of Natural Resources Canada will continue to assist with research into improved catalysts for hydrotreating of middle distillates, and new lower cost processes for upgrading middle distillates from synthetic and conventional crude oils to meet future product requirements. 5 refs., 1 tab

    State-of-the-art proton exchange membrane fuel cells (PEMFCs) anodically inhale H 2 fuel and cathodically expel water molecules. We show an unprecedented fuel cell concept exhibiting cathodic fuel exhalation capability of anodically inhaled fuel, driven by the neutralization energy on decoupling the direct acid-base chemistry. The fuel exhaling fuel cell delivered a peak power density of 70 mW/cm 2 at a peak current density of 160 mA/cm 2 with a cathodic H 2 output of ∼80 mL in 1 h. We illustrate that the energy benefits from the same fuel stream can at least be doubled by directing it through proposed neutralization electrochemical cell prior to PEMFC in a tandem configuration.

  18. The need for a marketing strategy for Alberta bitumen

    1993-01-01

    Over the past 15 years, government and industry have invested heavily in research and development of new technology for extracting bitumen from the Alberta oil sands. The results have been a dramatic increase in the fraction of oil sands deposits that could be economically exploited and a drop in production costs. However, no rapid increase in bitumen recovery has been achieved and most new bitumen production projects have been postponed or cancelled. This is the result of very variable prices for bitumen and the inadequacy of a marketing strategy which relies on the sale of raw bitumen. Options such as transport of bitumen to southern markets are limited by the need to reduce bitumen viscosity for pipelining and by the limited market for emulsified or diluted bitumen. Another possible strategy, conversion of the bitumen to synthetic crude oil, is limited by high costs, product characteristics (too much diesel and not enough gasoline), and a market limited to specialized refineries. A third strategy is to convert and refine bitumen to transportation fuels in Alberta, using inexpensive local natural gas, and transporting the products through existing pipeline facilities. 3 figs

  4. An economic evaluation of forest improvement opportunities and impacts from the emergence of a biomass fuel market in southwestern Nova Scotia

    International Nuclear Information System (INIS)

    Manley, A.L.; Savage, G.D.

    1993-01-01

    In 1991, Nova Scotia's public power utility initiated a process to purchase privately produced electrical power. A proposal was received to produce 20--25 megawatts from the burning of 350 to 400,000 tonnes annually of wood residue and forest biomass in a co-generation facility in southwestern Nova Scotia, Canada. This proposal has been proceeding and is nearing the construction phase. As a result of this potential market, there is an opportunity for increasing the scope and extent of forest improvement operations. Options for a closer integration of planning, harvesting, and silviculture activities will emerge. Optimum end use allocation could occur and enhance overall economic efficiency. The objective of this project is to assess the effect that this emerging market for forest biomass could have on forest management in the supply area. This project has two phases. Phase 1, presented here, develops the framework and methodology. Phase 2 will apply a linear programming-based analytical model for evaluation. Phase 1 accumulated the required data and information for both the current management and marketing situation and that including the emerging biomass market. Growth and yield of the natural stand types were calculated for a mixture of conventional roundwood products and chip equivalents. Management regimes, based on current forest type, site class, and appropriate silviculture treatments, were established. Expected multiproduct yields, by regime were estimated. Silviculture and harvest costs along with product revenues were used to calculate standing timber and soil expectation values. In Phase 2, a stand-based optimization model will be developed to explore and evaluate the long term opportunities and differences between the present and emerging management and market situations

    Open pit mining and in situ techniques, such as steam stimulation, are used to recover Alberta's bitumen and heavy oil resources, which have higher viscosities than conventional hydrocarbons. The bitumen is typically upgraded to synthetic crude oil (SCO). In the simplest processing scheme, the bitumen is blended with diluent for ease in pipeline transport and then processed at refineries with upgrading facilities. The bitumen is also upgraded to light SCO at world-scale upgraders in Alberta. The SCO is then processed at refineries in downstream markets. The 2 categories of upgrading, notably primary and secondary upgrading, were described in this article along with technology options for both categories. Slurry hydrocracking is regarded as the most interesting emerging residual fuel upgrading technology. It combines special catalyst mixes with the latest slurry reactor designs as well as innovative catalyst capture and recycle schemes to produce very high conversions and potentially superior upgrading economics. The increase in volume and rate of SCO from Alberta provides refiners in the oil sands marketing sector an unprecedented choice of opportunities to improve profitability. Key trends indicate that production will increase substantially from 2008 to 2030. 5 figs

    Because of its inexhaustible supplies hard fossil fuel will represent the pillar of the power systems of the 21st century. Only high-calorie fossil fuels have the market value and participate in the world trade. Low-calorie fossil fuels ((brown coal and lignite) are fuels spent on the spot and their value is indirectly expressed through manufactured kWh. For the purpose of determining the real value of a tonne of low-calorie coal, the criteria that help in establishing the value of a tonne of hard coal have to be corrected and thus evaluated and assessed at the market.

    ENSA is a well known manufacturer of multi-system primary components for the nuclear industry and is totally prepared to satisfy future market requirements in this industry. At the same time that ENSA has been gaining a reputation world wider for the supply of primary components, has been strengthening its commitment and experience in supplying spent fuel components, either pool racks or storage and transportation casks, and offers not only fabrication but also design capabilities for its products. ENSA has supplied Spent Fuel Pool Racks, in spain, Finland, Taiwan, Korea, China, and currently it is in the process of licensing its own rack design in the United States of America for the ESBWR along with Ge-Hitachi. ENSA has supplied racks for 20 pools and 22 different reactors and it has also manufactured racks under all available technologies and developed a design known as Interlock Cell Matrix whose main features are outlined in this article. Another ENSA achievement in rack technology is the use of remote control for re-racking activities instead of using divers, which improves the ALARA requirements. Regarding casks for storage and transportation, ENSA also has al leading worldwide position, with exports prevailing over the Spanish market where ENSA has supplied 16 storage and transportation casks to the Spanish nuclear power Trillo. In some cases, ENSA acts as subcontractor for other clients. Foreign markets are still a major challenge for ENSA. ENSA-is well known for its manufacturing capabilities in the nuclear industry, but has been always involved in design activities through its engineering division, which carries out different tasks: components Design; Tooling Design; Engineering and Documentation; Project Engineering; Calculations, Design and Development Engineering.

    The current state of the world's uranium market and its effect on US nuclear-fueled utilities is discussed. Major uranium-related issues that will confront US utility nuclear fuel managers in the coming years are presented, emphasizing the perspectives of supply, demand, world market adjustment, and US market restrictions on imports. It is stated that the US market is essential by non-US producers to help equilibrate an otherwise excessive supply which would cause chaos in the market. To avoid another ten-year boom/bust cycle, the US is urged to reexamine its position on long-term contracts - which permit greater price stability in contrast to the spot market and its price fluctuations. 13 figures, 6 tables

    2013-01-01

    Highlights: ► Composite design inspired by nature. ► Tuning microstructure via changing ceramic content and aspect ratio. ► Experimental display of structure–property correlationship in synthetic composites. - Abstract: Structural biocomposites (for example, nacre in seashells, bone, etc.) are designed according to the functional role they are delegated for. For instance, bone is primarily designed for withstanding time-dependent loading (for example, withstanding stresses while running, jumping, accidental fall) and hence the microstructure is designed primarily from enhanced toughness and moderate stiffness point of view. On the contrary, seashells (which lie in the abyss of oceans) apart from providing defense to the organism (it is hosting) against predatory attacks, are subjected to static loading (for example, enormous hydrostatic pressure). Hence, emphasis on the shell structure evolution is directed primarily towards providing enhanced stiffness. In order to conform between stiffness and toughness, nature precisely employs a staggered arrangement of inorganic bricks in a biopolymer matrix (at its most elementary level of architecture). Aspect ratio and content of ceramic bricks are meticulously used by nature to synthesize composites having varying degrees of stiffness, strength and toughness. Such an amazing capability of structure–property correlationship has rarely been demonstrated in synthetic composites. Therefore, in order to better understand the mechanical behavior of synthetic staggered composites, the problem becomes two-pronged: (a) synthesize composites with varying brick size and contents and (b) experimental investigation of the material response. In this article, an attempt has been made to synthesize and characterize staggered ceramic–polymer composites having varying aspect ratio and ceramic content using freeze-casting technique. This will in-turn help us in custom-design manufacture of hybrid bio-inspired composite materials

    1992-01-01

    This paper forecasts the photovoltaic (PV) market growth for the 1990s. Ten years of PV history are reviewed and used to establish market trends in terms of average selling price (ASP) and kilowatts shipped by market segment. The market is segmented into indoor consumer, stand-alone, and grid-connected applications. Indoor consumer presently represents a saturated market and is fairly predictable. The stand-alone market (i.e. not connected to the utility grid) is fairly stable and predictable. The utility PV market however is highly dependent on a number of market factors such as the cost of conventional energy the cost of PV systems utility acceptance of PV and regulatory controls. Government and institutional regulations, environmental issues, and OPEC and Middle East politics will have the greatest impact on the cost of conventional fuels. Private and federal investment in PV technology development could have a significant impact on the cost of PV systems. Forecasts are provided through the year 2000 for indoor consumer stand-alone and utility markets

SA imaging is a radical break with today's commercial systems, where the image is acquired sequentially one image line at a time. This puts a strict limit on the frame rate and the possibility of acquiring...... a sufficient amount of data for high precision flow estimation. These constrictions can be lifted by employing SA imaging. Here data is acquired simultaneously from all directions over a number of emissions, and the full image can be reconstructed from this data. The talk will demonstrate the many benefits...

    2015-03-17

    The catalytic diversity of living systems offers a broad range of opportunities for developing new methods to produce small molecule targets such as fuels, materials, and pharmaceuticals. In addition to providing cost-effective and renewable methods for large-scale commercial processes, the exploration of the unusual chemical phenotypes found in living organisms can also enable the expansion of chemical space for discovery of novel function by combining orthogonal attributes from both synthetic and biological chemistry. In this context, we have focused on the development of new fluorine chemistry using synthetic biology approaches. While fluorine has become an important feature in compounds of synthetic origin, the scope of biological fluorine chemistry in living systems is limited, with fewer than 20 organofluorine natural products identified to date. In order to expand the diversity of biosynthetically accessible organofluorines, we have begun to develop methods for the site-selective introduction of fluorine into complex natural products by engineering biosynthetic machinery to incorporate fluorinated building blocks. To gain insight into how both enzyme active sites and metabolic pathways can be evolved to manage and select for fluorinated compounds, we have studied one of the only characterized natural hosts for organofluorine biosynthesis, the soil microbe Streptomyces cattleya. This information provides a template for designing engineered organofluorine enzymes, pathways, and hosts and has allowed us to initiate construction of enzymatic and cellular pathways for the production of fluorinated polyketides.

    2014-03-28

    We analyse the pros and cons of analog versus digital computation in living cells. Our analysis is based on fundamental laws of noise in gene and protein expression, which set limits on the energy, time, space, molecular count and part-count resources needed to compute at a given level of precision. We conclude that analog computation is significantly more efficient in its use of resources than deterministic digital computation even at relatively high levels of precision in the cell. Based on this analysis, we conclude that synthetic biology must use analog, collective analog, probabilistic and hybrid analog-digital computational approaches; otherwise, even relatively simple synthetic computations in cells such as addition will exceed energy and molecular-count budgets. We present schematics for efficiently representing analog DNA-protein computation in cells. Analog electronic flow in subthreshold transistors and analog molecular flux in chemical reactions obey Boltzmann exponential laws of thermodynamics and are described by astoundingly similar logarithmic electrochemical potentials. Therefore, cytomorphic circuits can help to map circuit designs between electronic and biochemical domains. We review recent work that uses positive-feedback linearization circuits to architect wide-dynamic-range logarithmic analog computation in Escherichia coli using three transcription factors, nearly two orders of magnitude more efficient in parts than prior digital implementations.

    A yellow solid petroleum paraffin d/sup 60/ 0.808, I number 3.5, average molecular weight 350, chlorinated and condensed with benzene, xylene, or naphthalene by the Friedel and Crafts reaction, in the presence of anhydrous AlCl/sub 3/ or activated Al, gave synthetic lubricating oils. Xylene was the preferred aromatic compound, naphthalene required the use of less completely chlorinated paraffin, benzene produced resins difficult to remove and gave darker oils with excessive green fluorescence. Activated Al rather than anhydrous AlCl/sub 3/ gave darker oils with higher viscosity and Conradson C values. Tar from the low-temperature distillation of lignite, used as a source of a paraffin fraction melting 40/sup 0/ to 48/sup 0/ (chlorinated to 26.5 percent Cl) and an aromatic fraction, 45 percent aromatic compounds by volume (mainly polysubstituted benzenes), I number 10, was converted to a similar synthetic lubricant with the following properties: Kinematic viscosity at 210/sup 0/ F., 50.4 centistokes; viscosity index, 92; Conradson C, 1.5 percent; solidification point, 9/sup 0/; S, 0.41 percent.

  6. Coloring of synthetic fluorite

    1980-01-01

    A synthetic fluorite of the Harshaw Chemical Company is analyzed for rare earth elements, yttrium, and sodium. Samples of this fluorite are irradiated with X-rays, γ-rays, neutrons, electrons, protons, and α-particles at different energies, and their absorption spectra are analyzed. Analyzing the thermal bleaching of these radiation-coloured fluorites shows that both, impurities and radiation play a part in the coloration of synthetic fluorite. However, the main contribution comes from the radiation induced lattice defects. In the visible region spectra, the colour centre of the 5800 to 5900 A absorption band is probably mainly related with large aggregates of F-centres. The 5450 and the 5300 A absorption bands are mainly related to monovalent and divalent ion impurities and their association with lattice defects. The 3800 A absorption band seems to be related with F-centre aggregates. However, the contribution from the rare earth elements related complex color centres also plays some part for the production of this absorption band. These results indicate that the color centres of different origin can absorb light at the same wavelength. (author)

    The current trend of burn wound care has shifted to more holistic approach of improvement in the long-term form and function of the healed burn wounds and quality of life. This has demanded the emergence of various skin substitutes in the management of acute burn injury as well as post burn reconstructions. Skin substitutes have important roles in the treatment of deep dermal and full thickness wounds of various aetiologies. At present, there is no ideal substitute in the market. Skin substitutes can be divided into two main classes, namely, biological and synthetic substitutes. The biological skin substitutes have a more intact extracellular matrix structure, while the synthetic skin substitutes can be synthesised on demand and can be modulated for specific purposes. Each class has its advantages and disadvantages. The biological skin substitutes may allow the construction of a more natural new dermis and allow excellent re-epithelialisation characteristics due to the presence of a basement membrane. Synthetic skin substitutes demonstrate the advantages of increase control over scaffold composition. The ultimate goal is to achieve an ideal skin substitute that provides an effective and scar-free wound healing.

Skin substitutes have important roles in the treatment of deep dermal and full thickness wounds of various aetiologies. At present, there is no ideal substitute in the market. Skin substitutes can be divided into two main classes, namely, biological and synthetic substitutes. The biological skin substitutes have a more intact extracellular matrix structure, while the synthetic skin substitutes can be synthesised on demand and can be modulated for specific purposes. Each class has its advantages and disadvantages. The biological skin substitutes may allow the construction of a more natural new dermis and allow excellent re-epithelialisation characteristics due to the presence of a basement membrane. Synthetic skin substitutes demonstrate the advantages of increase control over scaffold composition. The ultimate goal is to achieve an ideal skin substitute that provides an effective and scar-free wound healing.

    2008-01-01

    This issue of Alternatives newsletter features 4 main articles dealing with: 1 - July 1, 2007 - electricity and gas markets open to competition: first telecommunications, now energy. Starting July 1, 2007, every one of the European Union's 500 million consumers is free to chose a supplier for electricity and natural gas. How will this work? A road map. 2 - Oil and gas pipelines, vital energy arteries: they criss-cross the planet over land and under sea, offering an alternative to sea lanes. How do these strategically placed pipelines work to transport fossil fuels? 3 - Warming of the Earth's northern latitudes: what are the consequences?: Dr. Oleg Anisimov, one of the experts on the Intergovernmental Panel on Climate Change (IPCC) that met in April 2007, reviews the consequences of human activity on permafrost, that huge expense of ice covering almost 20% of the Earth's surface. 4 - Nuclear power, an alternative to costly fossil fuels: part two of a report on the World energy outlook. This publication of the International Energy agency predicts that nuclear power will continue to be one of the main sources of energy supply for the next 25 years

  11. Low-rank coal study. Volume 4. Regulatory, environmental, and market analyses

    Energy Technology Data Exchange (ETDEWEB)

    1980-11-01

    The regulatory, environmental, and market constraints to development of US low-rank coal resources are analyzed. Government-imposed environmental and regulatory requirements are among the most important factors that determine the markets for low-rank coal and the technology used in the extraction, delivery, and utilization systems. Both state and federal controls are examined, in light of available data on impacts and effluents associated with major low-rank coal development efforts. The market analysis examines both the penetration of existing markets by low-rank coal and the evolution of potential markets in the future. The electric utility industry consumes about 99 percent of the total low-rank coal production. This use in utility boilers rose dramatically in the 1970's and is expected to continue to grow rapidly. In the late 1980's and 1990's, industrial direct use of low-rank coal and the production of synthetic fuels are expected to start growing as major new markets.

  12. The French biogas market by 2020. Injected biogas, co-generation, fuel biomethane, and so on: which challenges and perspectives for the market and the different actors on the medium term?

    International Nuclear Information System (INIS)

    2016-03-01

    As the French biogas market keeps on developing, as its growth potential on the medium term is doubtless, and as always more farmers and waste-water treatment plants are equipped with biogas plants, many technical problems remain to be solved, objectives will not be reached, and new regulations and measures are introduced by public authorities to support the sector. In order to provide an overview of this context, this report proposes an analysis of the market and of its perspectives (presentation of determining factors, analysis of the activity evolution until 2015, analysis of the main biogas producing sectors, provisional scenario by 2020), an analysis of the external environment (support measures, impact of regulation, assessments of waste supplies, focus on some other structural factors like economy de-industrialisation and difficult acceptance of biogas projects). The report also analyses the business model of operators (income, financing, investments, burdens, relationships between actors) and their financial situation (site profitability, over-costs related to technical difficulties). The last part addresses challenges and highlights: sector consolidation (takeovers, construction of large sites), new perspectives of valorisation with presentation of a case study, security of supplies through partnerships, and technique improvements

  13. Creating a super market

    Katz, M.

    1994-01-01

    FERC (Federal Energy Regulatory Commission) Order 636 changed gas marketing procedures in October 1993 by disengaging the remaining linkages between producers, pipeline companies and LDCs. By erasing the pipelines' already disappearing role as gas suppliers, Order 636 made LDCs entirely responsible for obtaining their own gas supply, transportation and storage. So, many LDCs turned to gas marketing companies -- not only for more gas, but also for many of the services that the pipelines and gas suppliers used to provide. The process is giving the gas marketing companies a whole new role in life -- perhaps even a whole new life. Unlike LDCs and the pipelines, gas marketers are largely unregulated and, as such, are moving into or looking at a host of new areas: Helping customers manage and economize their energy use, not only with natural gas but with other fuels as well; Marketing electricity and fuel oil in addition to natural gas; Laying pipelines and serving local industrial customers the LDCs haven't been able to serve economically; and Selling natural gas to individual residential customers, the last remaining exclusive domain of the LDCs. The paper discusses the new roles for gas marketing companies and what is left for LDCs

  15. Potential Fusion Market for Hydrogen Production Under Environmental Constraints

    International Nuclear Information System (INIS)

    Konishi, Satoshi

    2005-01-01

    Potential future hydrogen market and possible applications of fusion were analyzed. Hydrogen is expected as a major energy and fuel mediun for the future, and various processes for hydrogen production can be considered as candidates for the use of fusion energy. In order to significantly contribute to reduction of CO 2 emission, fusion must be deployed in developing countries, and must substitute fossil based energy with synthetic fuel such as hydrogen. Hydrogen production processes will have to evaluated and compared from the aspects of energy efficiency and CO 2 emission. Fusion can provide high temperature heat that is suitable for vapor electrolysis, thermo-chemical water decomposition and steam reforming with biomass waste. That is a possible advantage of fusion over renewables and Light water power reactor. Despite of its technical difficulty, fusion is also expected to have less limitation for siting location in the developing countries. Under environmental constraints, fusion has a chance to be a major primary energy source, and production of hydrogen enhances its contribution, while in 'business as usual', fusion will not be selected in the market. Thus if fusion is to be largely used in the future, meeting socio-economic requirements would be important

  18. Balancing the market

    International Nuclear Information System (INIS)

    Steve Kidd

    2007-01-01

    The uranium market still retains arrangements developed in the mists of time, but now is an appropriate time for something new to be developed. Quoted uranium prices continue to move sharply upwards. It can be argued that the long period of price depression followed by such a dramatic spike indicates that the uranium market is not functioning as it really should. Nevertheless, the particular characteristics of the uranium business should ensure that it should arguably have much calmer market conditions. Much of the problem relates to lack of market liquidity and transparency. Prices are published on a weekly and monthly basis by informed observers and are based on information they glean from market participants.The infrastructure issue of much of the nuclear fuel supply business is slowly but surely getting addressed by the required new investment, but the uranium market is still in need of something new.The question then remains about the longer-term market. To some extent, having a more transparent and liquid spot market will go some way towards addressing this. It will undoubtedly take some entrepreneurial leadership to induce this to happen, plus realisation that the current marketplace cannot be in the long-term interest of either buyers or sellers.

    Many of the deficiencies with human tissue epikeratoplasty might be improved by the use of a suitable synthetic lenticule. Potential biomaterials for epikeratoplasty include collagen (types I, III, or IV), collagen-hydrogel copolymers, bioactive synthetics, and coated hydrogels. The biomaterial must be engineered to achieve strict specifications of optical clarity, support of epithelial migration and adhesion, permeability to solutes, and stability to corneal proteases. Attaching synthetic lenticules to the cornea without cutting Bowman's layer by adhesives, laser welding, or direct adhesion may also improve the efficacy of synthetic epikeratoplasty.

    2017-03-01

    Synthetic biology is an emerging interdisciplinary field of biotechnology that involves applying the principles of engineering and chemical design to biological systems. Biosafety professionals have done an excellent job in addressing research laboratory safety as synthetic biology and gene editing have emerged from the larger field of biotechnology. Despite these efforts, risks posed by synthetic biology are of increasing concern as research procedures scale up to industrial processes in the larger bioeconomy. A greater number and variety of workers will be exposed to commercial synthetic biology risks in the future, including risks to a variety of workers from the use of lentiviral vectors as gene transfer devices. There is a need to review and enhance current protection measures in the field of synthetic biology, whether in experimental laboratories where new advances are being researched, in health care settings where treatments using viral vectors as gene delivery systems are increasingly being used, or in the industrial bioeconomy. Enhanced worker protection measures should include increased injury and illness surveillance of the synthetic biology workforce; proactive risk assessment and management of synthetic biology products; research on the relative effectiveness of extrinsic and intrinsic biocontainment methods; specific safety guidance for synthetic biology industrial processes; determination of appropriate medical mitigation measures for lentiviral vector exposure incidents; and greater awareness and involvement in synthetic biology safety by the general occupational safety and health community as well as by government occupational safety and health research and regulatory agencies.

  1. Finding Hope in Synthetic Biology.

    2017-04-01

    For some, synthetic biology represents great hope in offering possible solutions to many of the world's biggest problems, from hunger to sustainable development. Others remain fearful of the harmful uses, such as bioweapons, that synthetic biology can lend itself to, and most hold that issues of biosafety are of utmost importance. In this article, I will evaluate these points of view and conclude that although the biggest promises of synthetic biology are unlikely to become reality, and the probability of accidents is fairly substantial, synthetic biology could still be seen to benefit humanity by enhancing our ethical understanding and by offering a boost to world economy.

    1989-01-01

    Computational synthetic geometry deals with methods for realizing abstract geometric objects in concrete vector spaces. This research monograph considers a large class of problems from convexity and discrete geometry including constructing convex polytopes from simplicial complexes, vector geometries from incidence structures and hyperplane arrangements from oriented matroids. It turns out that algorithms for these constructions exist if and only if arbitrary polynomial equations are decidable with respect to the underlying field. Besides such complexity theorems a variety of symbolic algorithms are discussed, and the methods are applied to obtain new mathematical results on convex polytopes, projective configurations and the combinatorics of Grassmann varieties. Finally algebraic varieties characterizing matroids and oriented matroids are introduced providing a new basis for applying computer algebra methods in this field. The necessary background knowledge is reviewed briefly. The text is accessible to stud...

    2017-01-01

    This landmark monograph presents the most recent mathematical developments in the analysis of ionospheric distortions of SAR images and offers innovative new strategies for their mitigation. As a prerequisite to addressing these topics, the book also discusses the radar ambiguity theory as it applies to synthetic aperture imaging and the propagation of radio waves through the ionospheric plasma, including the anisotropic and turbulent cases. In addition, it covers a host of related subjects, such as the mathematical modeling of extended radar targets (as opposed to point-wise targets) and the scattering of radio waves off those targets, as well as the theoretical analysis of the start-stop approximation, which is used routinely in SAR signal processing but often without proper justification. The mathematics in this volume is clean and rigorous – no assumptions are hidden or ambiguously stated. The resulting work is truly interdisciplinary, providing both a comprehensive and thorough exposition of the field,...

  7. Radioimmunoassay of synthetic steroids

    Energy Technology Data Exchange (ETDEWEB)

    Raynaud, J -P; Bucourt, R; Salmon, J

    1975-12-01

    The sensitivity of a radioimmunoassay depends on the intrinsic association constant of the interaction between ligand and antibody. Its specificity depends on the position of the chain which forms the link with the antigen. Thus, an antibody specific of estradiol has been obtained by coupling estradiol to albumin via a chain at position 7. For synthetic steroids the structure of which is sufficiency different from that of natural hormones, the requirements for a sensitive assay method not involving chromatography are simply maximum affinity and positioning of the couple at a site which does not undergo metabolic attack. These criteria were used to develop assays for R 2858 and R 2453 which obviate the need to administer radioactive product in clinical pharmacology. Cross-reaction with structural analogs may be used to assay competitors. Thus, R 2323 antibody, highly specific for endogenous steroids, may be used to assay other trienes such as R 1697 (trenbolone) and R 2010 (norgestrienone).

    Battelle's Economic Analysis of PEM Fuel Cell Systems project was initiated in 2003 to evaluate the technology and markets that are near-term and potentially could support the transition to fuel cells in automotive markets. The objective of Battelle?s project was to assist the DOE in developing fuel cell systems for pre-automotive applications by analyzing the technical, economic, and market drivers of direct hydrogen PEM fuel cell adoption. The project was executed over a 6-year period (2003 to 2010) and a variety of analyses were completed in that period. The analyses presented in the final report include: Commercialization scenarios for stationary generation through 2015 (2004); Stakeholder feedback on technology status and performance status of fuel cell systems (2004); Development of manufacturing costs of stationary PEM fuel cell systems for backup power markets (2004); Identification of near-term and mid-term markets for PEM fuel cells (2006); Development of the value proposition and market opportunity of PEM fuel cells in near-term markets by assessing the lifecycle cost of PEM fuel cells as compared to conventional alternatives used in the marketplace and modeling market penetration (2006); Development of the value proposition of PEM fuel cells in government markets (2007); Development of the value proposition and opportunity for large fuel cell system application at data centers and wastewater treatment plants (2008); Update of the manufacturing costs of PEM fuel cells for backup power applications (2009).

    1993-01-01

    Synthetic rubber markets in North America bounced back in no uncertain terms last year, with demand climbing an impressive 9.5%, to 2.97 million m.t.; and, according to the International Institute of Synthetic Rubber Producers (IIS-RP; Houston) latest five-year forecast, producers can look forward to a 3.3% increase in demand during 1993. This growth rate outpaced out 1992 forecast and demonstrates the resilience of the synthetic rubber industry, says William E. Tessemer, managing director of IISRP. We expect demand in 1993 to surpass 1992 and level off at a 2%/year growth rate for synthetic rubber - 2.5% including thermoplastic elastomers [TPEs]-over the 1993-97 period. The improvement reflects signs of a recovery in North America, especially the pickup in the auto and tire industry. The two major tire rubbers - styrene butadiene and polybutadiene rubber - notched up double-digit gains, and other materials that have autos uses, such as nitrile rubber and many of the specialty elastomers, also advanced strongly

    Yeasts are efficient biofuel producers with numerous advantages outcompeting bacterial counterparts. While most synthetic biology tools have been developed and customized for bacteria especially for Escherichia coli, yeast synthetic biological tools have been exploited for improving yeast to produce fuels and chemicals from renewable biomass. Here we review the current status of synthetic biological tools and their applications for biofuel production, focusing on the model strain Saccharomyces cerevisiae We describe assembly techniques that have been developed for constructing genes, pathways, and genomes in yeast. Moreover, we discuss synthetic parts for allowing precise control of gene expression at both transcriptional and translational levels. Applications of these synthetic biological approaches have led to identification of effective gene targets that are responsible for desirable traits, such as cellulosic sugar utilization, advanced biofuel production, and enhanced tolerance against toxic products for biofuel production from renewable biomass. Although an array of synthetic biology tools and devices are available, we observed some gaps existing in tool development to achieve industrial utilization. Looking forward, future tool development should focus on industrial cultivation conditions utilizing industrial strains. © FEMS 2015. All rights reserved.

    Purpose: To prevent bending of fuel rods caused by the difference of irradiation growth between coupling fuel rods and standards fuel rods thereby maintain the fuel rod integrity. Constitution: The f value for a fuel can (the ratio of pole of zirconium crystals in the entire crystals along the axial direction of the fuel can) of a coupling fuel rod secured by upper and lower tie plates is made smaller than the f value for the fuel can of a standard fuel rod not secured by the upper and the lower tie plates. This can make the irradiation growth of the fuel can of the coupling fuel rod greater than the irradiation growth of the fuel can of the standard fuel rod and, accordingly, since the elongation of the standard fuel rod can always by made greater, bending of the standard fuel rod can be prevented.

  17. Fuel cells - a perspective

    International Nuclear Information System (INIS)

    Biegler, T.

    2005-01-01

    Unfortunately, fuel cell publicity conveys expectations and hopes that are often based on uncritical interpretations of the underlying science. The aim here is to use that science to analyse how the technology has developed and what can realistically be delivered by fuel cells. There have been great achievements in fuel cell technology over the past decade, with most types reaching an advanced stage of engineering development. But there has been some muddled thinking about one critical aspect, fuel cell energy efficiency. The 'Carnot cycle' argument, that fuel cells must be much more efficient than heat engines, is a red herring, of no help in predicting real efficiencies. In practice, fuel cells are not always particularly efficient and there are good scientific reasons for this. Cost reduction is a big issue for fuel cells. They are not in principle especially simple devices. Better engineering and mass production will presumably bring costs down, but because of their inherent complexity there is no reason to expect them to be cheap. It is fair to conclude that predictions of fuel cells as commonplace components of energy systems (including a hydrogen economy) need to be treated with caution, at least until major improvements eventuate. However, one type, the direct methanol fuel cell, is aimed at a clear existing market in consumer electronics

    A significant expansion of the bioethanol production in Brazil could be a national developing project. As a matter of fact, aiming to reduce the dependence upon the fossil fuels, various countries have been incremented the use of bioethanol in their energetic matrix, not only to add directly to the gasoline but also to the fabrication of carburan. Many countries programs are specially highlighted, which have fixed goals of participation of biofuels in their matrixes to terms less than 20 years. In this book, the necessary conditions will be examined in order the Brazil to attend to sugar cane bioethanol world demand for replacing approximately 10% of the gasoline global consumption in the year 2025, which could correspond to a production of 205 billions of bioethanol liters per year, requiring an additional area of 24 Mha for the sugar cane cultivation.

    This report provides supplemental information to the assessment of target markets provided in Appendix A of the 2012 Next Generation Nuclear Plant (NGNP) Industry Alliance (NIA) business plan [NIA 2012] for deployment of High Temperature Gas-Cooled Reactors (HTGRs) in the 2025 – 2050 time frame. This report largely reiterates the [NIA 2012] assessment for potential deployment of 400 to 800 HTGR modules (100 to 200 HTGR plants with 4 reactor modules) in the 600-MWt class in North America by 2050 for electricity generation, co-generation of steam and electricity, oil sands operations, hydrogen production, and synthetic fuels production (e.g., coal to liquids). As the result of increased natural gas supply from hydraulic fracturing, the current and historically low prices of natural gas remain a significant barrier to deployment of HTGRs and other nuclear reactor concepts in the U.S. However, based on U.S. Department of Energy (DOE) Energy Information Agency (EIA) data, U.S. natural gas prices are expected to increase by the 2030 – 2040 timeframe when a significant number of HTGR modules could be deployed. An evaluation of more recent EIA 2013 data confirms the assumptions in [NIA 2012] of future natural gas prices in the range of approximately $7/MMBtu to $10/MMBtu during the 2030 – 2040 timeframe. Natural gas prices in this range will make HTGR energy prices competitive with natural gas, even in the absence of carbon-emissions penalties. Exhibit ES-1 presents the North American projections in each market segment including a characterization of the market penetration logic. Adjustments made to the 2012 data (and reflected in Exhibit ES-1) include normalization to the slightly larger 625MWt reactor module, segregation between steam cycle and more advanced (higher outlet temperature) modules, and characterization of U.S. synthetic fuel process applications as a separate market segment.
