    Energy Technology Data Exchange (ETDEWEB)

    Hurlbut, D. J.; Haase, S.; Turchi, C. S.; Burman, K.

    2012-06-01

    In January 2012, the National Renewable Energy Laboratory delivered to the Department of the Interior the first part of a study on Navajo Generating Station (Navajo GS) and the likely impacts of BART compliance options. That document establishes a comprehensive baseline for the analysis of clean energy alternatives, and their ability to achieve benefits similar to those that Navajo GS currently provides. This analysis is a supplement to NREL's January 2012 study. It provides a high level examination of several clean energy alternatives, based on the previous analysis. Each has particular characteristics affecting its relevance as an alternative to Navajo GS. It is assumed that the development of any alternative resource (or portfolio of resources) to replace all or a portion of Navajo GS would occur at the end of a staged transition plan designed to reduce economic disruption. We assume that replacing the federal government's 24.3% share of Navajo GS would be a cooperative responsibility of both the U.S. Bureau of Reclamation (USBR) and the Central Arizona Water Conservation District (CAWCD).

  2. Nuclear energy as almost unique alternative for future clean reliable power

    International Nuclear Information System (INIS)

    The oil peak is predicted to appear by the end of 2020, which opens a wide range of options for the mankind from self-annihilation to the smartest energetic solutions. The thermal pollution having so low efficiency is still acceptable if no carbon is burned. There is a planetary thermal limitation to several Pw (1015 W), representing less than 1% from the total power received from the sun. This shows that the energy production may grow another 1000 times without visible consequences. The need for the nuclear power replacement of the actual thermal power plants is of about 1 Tw (1012 W), representing about 1000 nuclear reactors. Knowing that 1 Gw thermal power reactor requires an average 100 tons of fuel per year, there will be a serious shortage of nuclear fuel, as soon as this program will be launched. There are other opportunities offered by the nuclear power related to the hydrogen-powered transportation, which come to solve the other aspect of the carbon-based pollution. In spite of all these advantages the nuclear power is the giant able to solve the mankind's problems for the next 1000 years. Unfortunately, this is now a giant with clay legs if the fuel and waste economy are not well set, by minimizing the amount of fuel immobilized as waste and a better waste treatment. The nuclear energy is not the unique energetic alternative, the use of renewable energie in planetary cooperation is by far the best option, but there is an imperious need to back them by strong, clean and compact nuclear sources

  9. Hydrogen as alternative clean fuel: Economic analysis

    International Nuclear Information System (INIS)

    In analogy to biofuel production from biomasses, the electrolytic conversion of other renewable energies into hydrogen as an alternative clean fuel is considered. This solution allows the intermittent renewable energy sources, as photovoltaics and wind energy, to enhance their development and enlarge the role into conventional fuel market. A rough economic analysis of hydrogen production line shows the costs, added by electrolysis and storage stages, can be recovered by properly accounting for social and environmental costs due to whole cycle of conventional fuels, from production to use. So, in a perspective of attaining the economic competitiveness of renewable energy, the hydrogen, arising from intermittent renewable energy sources, will be able to compete in the energy market with conventional fuels, making sure that their substitution will occur in a significant amount and the corresponding environment

    In 2003, the National Association of Regulatory Utility Commissioners (NARUC) and National Energy Technology Laboratories (NETL) collaboratively established the International Clean Energy Coalition (ICEC). The coalition consisting of energy policy-makers, technologists, and financial institutions was designed to assist developing countries in forming and supporting local approaches to greenhouse gas mitigation within the energy sector. ICEC's work focused on capacity building and clean energy deployment in countries that rely heavily on fossil-based electric generation. Under ICEC, the coalition formed a steering committee consisting of NARUC members and held a series of meetings to develop and manage the workplan and define successful outcomes for the projects. ICEC identified India as a target country for their work and completed a country assessment that helped ICEC build a framework for discussion with Indian energy decisionmakers including two follow-on in-country workshops. As of the conclusion of the project in 2010, ICEC had also conducted outreach activities conducted during United Nations Framework Convention on Climate Change (UNFCCC) Ninth Conference of Parties (COP 9) and COP 10. The broad goal of this project was to develop a coalition of decision-makers, technologists, and financial institutions to assist developing countries in implementing affordable, effective and resource appropriate technology and policy strategies to mitigate greenhouse gas emissions. Project goals were met through international forums, a country assessment, and in-country workshops. This project focused on countries that rely heavily on fossil-based electric generation.

This tool has been used to provide assistance to several projects in the Northeast, Mid-Atlantic, Intermountain and Pacific Regions. The tool was disseminated to the CEACs and supplemented by a Training Webinar and a How to Guide IDEA produced a US Community Energy Development Guide to support mayors, planners, community leaders, real estate developers and economic development officials who are interested in planning more sustainable urban energy infrastructure, creating community energy master plans and implementing CHP/ District Energy systems in cities, communities and towns. IDEA has collected industry data and provided a comprehensive data set containing information on District Energy installations in the US. District energy systems are present in 49 states and the District of Columbia. Of the 597 systems 55% were DE alone while the remainder was some combination of CHP, district heating, and district cooling. District energy systems that do not currently involve electric generation are strong near-term candidates for the adoption of CHP due to the magnitude of their aggregated thermal load. This data has helped inform specific and targeted initiatives including technical assistance provided by the CEAC’s for EPA’s Boiler MACT Compliance by large District Heating System boilers. These outcomes have been greatly enabled by the close coordination and collaboration with DOE CEAC leadership and with the eight regional US DOE Clean Energy Application Centers and the award’s incremental funding has allowed IDEA to leverage our resources to be an effective champion for Clean Energy.

    The Clean Energy Infrastructure Educational Initiative represents a collaborative effort by the University of Dayton, Wright State University and Sinclair Community College. This effort above all aimed to establish energy related programs at each of the universities while also providing outreach to the local, state-wide, and national communities. At the University of Dayton, the grant has aimed at: solidfying a newly created Master's program in Renewable and Clean Energy; helping to establish and staff a regional sustainability organization for SW Ohio. As well, as the prime grantee, the University of Dayton was responsible for insuring curricular sharing between WSU and the University of Dayton. Finally, the grant, through its support of graduate students, and through cooperation with the largest utilities in SW Ohio enabled a region-wide evaluation of over 10,000 commercial building buildings in order to identify the priority buildings in the region for energy reduction. In each, the grant has achieved success. The main focus of Wright State was to continue the development of graduate education in renewable and clean energy. Wright State has done this in a number of ways. First and foremost this was done by continuing the development of the new Renewable and Clean Energy Master's Degree program at Wright State . Development tasks included: continuing development of courses for the Renewable and Clean Energy Master's Degree, increasing the student enrollment, and increasing renewable and clean energy research work. The grant has enabled development and/or improvement of 7 courses. Collectively, the University of Dayton and WSU offer perhaps the most comprehensive list of courses in the renewable and clean energy area in the country. Because of this development, enrollment at WSU has increased from 4 students to 23. Secondly, the grant has helped to support student research aimed in the renewable and clean energy program.

  6. Clean Cities Guide to Alternative Fuel Commercial Lawn Equipment (Brochure)

    Energy Technology Data Exchange (ETDEWEB)

    2011-10-01

    Guide explains the different types of alternative fuel commercial mowers and lists the makes and models of the ones available on the market. Turf grass is a fixture of the American landscape and the American economy. It is the nation's largest irrigated crop, covering more than 40 million acres. Legions of lawnmowers care for this expanse during the growing season-up to year-round in the warmest climates. The annual economic impact of the U.S. turf grass industry has been estimated at more than $62 billion. Lawn mowing also contributes to the nation's petroleum consumption and pollutant emissions. Mowers consume 1.2 billion gallons of gasoline annually, about 1% of U.S. motor gasoline consumption. Commercial mowing accounts for about 35% of this total and is the highest-intensity use. Large property owners and mowing companies cut lawns, sports fields, golf courses, parks, roadsides, and other grassy areas for 7 hours per day and consume 900 to 2,000 gallons of fuel annually depending on climate and length of the growing season. In addition to gasoline, commercial mowing consumes more than 100 million gallons of diesel annually. Alternative fuel mowers are one way to reduce the energy and environmental impacts of commercial lawn mowing. They can reduce petroleum use and emissions compared with gasoline- and diesel-fueled mowers. They may also save on fuel and maintenance costs, extend mower life, reduce fuel spillage and fuel theft, and promote a 'green' image. And on ozone alert days, alternative fuel mowers may not be subject to the operational restrictions that gasoline mowers must abide by. To help inform the commercial mowing industry about product options and potential benefits, Clean Cities produced this guide to alternative fuel commercial lawn equipment. Although the guide's focus is on original equipment manufacturer (OEM) mowers, some mowers can be converted to run on alternative fuels. For more information about propane

    weighed again showing typical contaminant deposition levels of approximately 0.00300g per part. They were then cleaned by the solvent or process being tested and then weighed a third time which allowed for the calculation of the cleaning efficiency of the test solvent or process.Based on preliminary experiments, five solvents (ethanol, isopropanol, acetone, ethyl acetate, and tert-butyl acetate) were down selected for further testing. When coupled with ultrasonic agitation, these solvents removed hydrocarbon contaminants as well as Vertrel MCA and showed improved removal of perfluorinated greases. Supercritical carbon dioxide did an excellent job dissolving each of the five contaminants but did a poor job of removing Teflon particles found in the perfluorinated greases. Plasma cleaning efficiency was found to be dependent on which supply gas was used, exposure time, and gas pressure. Under optimized conditions it was found that breathing air, energized to the plasma phase, was able to remove nearly 100% of the contamination.These findings indicate that alternative cleaning methods are indeed able to achieve precision levels of cleanliness. Currently, our team is working with a commercial cleaning company to get independent verification of our results. We are also evaluating the technical and financial aspects of scaling these processes to a size capable of supporting the future cleaning needs of KSC.

    Alternative energy technologies are greatly hindered by significant limitations in materials science. From low activity to poor stability, and from mineral scarcity to high cost, the current materials are not able to cope with the significant challenges of clean energy technologies. However, recent advances in the preparation of nanomaterials, porous solids, and nanostructured solids are providing hope in the race for a better, cleaner energy production. The present contribution critically reviews the development and role of mesoporosity in a wide range of technologies, as this provides for critical improvements in accessibility, the dispersion of the active phase and a higher surface area. Relevant examples of the development of mesoporosity by a wide range of techniques are provided, including the preparation of hierarchical structures with pore systems in different scale ranges. Mesoporosity plays a significant role in catalysis, especially in the most challenging processes where bulky molecules, like those obtained from biomass or highly unreactive species, such as CO2 should be transformed into most valuable products. Furthermore, mesoporous materials also play a significant role as electrodes in fuel and solar cells and in thermoelectric devices, technologies which are benefiting from improved accessibility and a better dispersion of materials with controlled porosity.

    dilute concentration environment resulted in carbon steel corrosion rates that were less than 150 mpy. These rates are manageable in that chemical cleaning processes could proceed for limited time without significant wall loss. Further optimization of the Alternative Enhance Chemical Cleaning (AECC) process should focus on testing in solutions of this dilute concentration and low temperature regime. (2) In general, for the nitric acid based reagent, the aluminum oxide phase environments resulted in higher corrosion rates than the iron oxide phase environments. (3) In general, for the sulfuric acid based reagent, the iron oxide phase environments resulted in higher corrosion rates than the aluminum oxide phase environments. (4) In general, for the nitric acid based reagent, the HM sludge simulant environments resulted in higher corrosion rates than the PUREX sludge simulant environments. This result agrees with the previous observation that the aluminum oxide phases are more aggressive than the iron oxide phase environments in the nitric acid reagent. (5) Pitting was more likely to occur in the sulfuric acid based reagents than in the nitric acid based reagents. (6) Pitting occurred only in the iron based pure oxide phases and the sludge simulants. No pitting was observed in the aluminum based pure oxide phases. (7) Pitting tended to occur more frequently in tests that involved the dilute mineral acid reagent. (8) Pitting was more severe at the higher temperature for a given mineral acid concentration. (9) Pitting was more severe at a higher mineral acid concentration for a given temperature. (10) Based on the combined results of the open circuit potential and cathodic polarization testing, there was a low propensity for hydrogen evolution in solutions where sludge has been dissolved.

To realize highly efficient utilization of coal, low pollution and low cost are great and impendent tasks. These difficult problems can be almost resolved through establishing large-scale pithead power stations using two-stage highly efficient dry coal-cleaning system before coal burning, which is a highly efficient, clean and economical strategy considering the current energy and environmental status of China. All these will be discussed in detail in this paper.

  18. Alternative bio-based fuels for aviation: the clean airports program

    International Nuclear Information System (INIS)

    The Renewable Aviation Fuels Development Center at Baylor University in Waco, Texas, has been designated as the national coordinator of the Clean Airports Program. The U.S. Dept. of Energy (US DOE) conferred this designation in March 1996. This program, a spin-off of the Clean Cities Program, was initiated to increase the use of alternative fuels in aviation. The two major fuels used in aviation are the current piston engine aviation gasoline and the current turbine engine fuel. The environmental impact of each of these fuels is significant. Aviation gasoline (100LL), currently used in the general aviation piston engine fleet, contributes 100% of the emissions containing lead in the U.S. today. Turbine engine fuel (jet fuel) produces two major environmental impacts: a local one, in the vicinity of the airports, and a global impact on climate change. The Clean Airports Program was established to achieve and maintain clean air at and in the vicinity of airports, through the use of alternative fuel-powered air and ground transportation vehicles.

    New methods are needed to accelerate clean energy policy adoption. To that end, this study proposes an innovative financing scheme for renewable and energy efficiency deployment. Financing barriers represent a notable obstacle for energy improvements and this is particularly the case for low income households. Implementing a policy such as PACE—property assessed clean energy—allows for the provision of upfront funds for residential property owners to install electric and thermal solar systems and make energy efficiency improvements to their buildings. This paper will inform the design of better policies tailored to the creation of the appropriate conditions for such investments to occur, especially in those countries where most of the population belongs to the low-middle income range facing financial constraints.

    Many factors have emerged for change towards cleaner and more efficient technologies and services: climate change, increasing oil demands, and rising living standards in many parts of the world are putting an ever-increasing strain on the environment. Recently, these drivers have fueled the formation of a clean energy venture capital market where both independent venture capitalists (VCs) and corporate venture capitalists (CVCs) have invested in clean energy start-ups. Financing of clean energy market creation is the focus of this dissertation. The dissertation contributes to several bodies of literature in the area of entrepreneurship, new industry creation, corporate venturing, and venture capital research. The dissertation uses a grounded theory approach. The study is guided by three data collection approaches with an emphasis on the first two. First, interviews with European and North American VC and CVC firms that have invested in the clean energy sector were carried out. Second, a clean energy venture financing survey that consisted of qualitative, essay-format questions and some quantitative questions was carried out. Third, interviews with clean energy stakeholders were carried out in order to gain a better understanding of the emerging sector. The research results consist of three main findings. First, the research results suggest that clean energy ventures face the following three main entrepreneurial challenges: financing, market education, and growth management. A further study of three clean energy industry categories revealed additional challenges that varied according to the industry development stage. Second, the results demonstrate that, from a venture capitalist perspective, clean energy venture risk characteristics can be divided into two groups: generally recognized risk characteristics and cognitive risk characteristics. The identified generally recognized risk characteristics were market demand and adaptation, incompatibility with the VC model

    The author discusses efforts by the Asia Alternative Energy Unit (ASTAE) of the World Bank in supporting alternative energy source projects in Asia. Energy growth rates have been as high as 18% per year, with power capacity doubling each decade in the 1960`s, 70`s and 80`s. Much of this has come from fossil fuel projects coupled with major hydroelectric projects. One consequence is developing air pollution loads originating in Asia. ASTAE has been supporting pilot programs in applying alternative energy sources. The goal has been to mainstream renewable energy sources in World Bank operations, by working with managers from different countries to: include renewable energy in country assistance strategies and sectorial development plans; provide assistance to renewable energy initiatives; expand initiatives to new countries, sectors and technologies.

    Zheng, Nina; Fridley, David

    2011-06-15

    In addition to promoting energy efficiency, China has actively pursued alternative energy development as a strategy to reduce its energy demand and carbon emissions. One area of particular focus has been to raise the share of alternative energy in China’s rapidly growing electricity generation with a 2020 target of 15% share of total primary energy. Over the last ten years, China has established several major renewable energy regulations along with programs and subsidies to encourage the growth of non-fossil alternative energy including solar, wind, nuclear, hydro, geothermal and biomass power as well as biofuels and coal alternatives. This study thus seeks to examine China’s alternative energy in terms of what has and will continue to drive alternative energy development in China as well as analyze in depth the growth potential and challenges facing each specific technology. This study found that despite recent policies enabling extraordinary capacity and investment growth, alternative energy technologies face constraints and barriers to growth. For relatively new technologies that have not achieved commercialization such as concentrated solar thermal, geothermal and biomass power, China faces technological limitations to expanding the scale of installed capacity. While some alternative technologies such as hydropower and coal alternatives have been slowed by uneven and often changing market and policy support, others such as wind and solar PV have encountered physical and institutional barriers to grid integration. Lastly, all alternative energy technologies face constraints in human resources and raw material resources including land and water, with some facing supply limitations in critical elements such as uranium for nuclear, neodymium for wind and rare earth metals for advanced solar PV. In light of China’s potential for and barriers to growth, the resource and energy requirement for alternative energy technologies were modeled and scenario analysis

    Providing clean water and energy for about nine billion people on the earth by midcentury is a daunting challenge. Major investments in efficiency of energy and water use and deployment of all economical energy sources will be needed. Separations technology has an important role to play in producing both clean energy and water. Some examples are carbon dioxide capture and sequestration from fossil energy power plants and advanced nuclear fuel cycle scemes. Membrane separations systems are under development to improve the economics of carbon capture that would be required at a huge scale. For nuclear fuel cycles, only the PUREX liquid-liquid extraction process has been deployed on a large scale to recover uranium and plutonium from used fuel. Most current R and D on separations technology for used nuclear fuel focuses on ehhancements to a PUREX-type plant to recover the minor actinides (neptunium, americiu, and curium) and more efficiently disposition the fission products. Are there more efficient routes to recycle the actinides on the horizon? Some new approaches and barriers to development will be briefly reviewed.

  7. Clean option: An alternative strategy for Hanford Tank Waste Remediation

    International Nuclear Information System (INIS)

    Disposal of high-level tank wastes at the Hanford Site is currently envisioned to divide the waste between two principal waste forms: glass for the high-level waste (HLW) and grout for the low-level waste (LLW). The draft flow diagram shown in Figure 1.1 was developed as part of the current planning process for the Tank Waste Remediation System (TWRS), which is evaluating options for tank cleanup. The TWRS has been established by the US Department of Energy (DOE) to safely manage the Hanford tank wastes. It includes tank safety and waste disposal issues, as well as the waste pretreatment and waste minimization issues that are involved in the ''clean option'' discussed in this report. This report describes the results of a study led by Pacific Northwest Laboratory to determine if a more aggressive separations scheme could be devised which could mitigate concerns over the quantity of the HLW and the toxicity of the LLW produced by the reference system. This aggressive scheme, which would meet NRC Class A restrictions (10 CFR 61), would fit within the overall concept depicted in Figure 1.1; it would perform additional and/or modified operations in the areas identified as interim storage, pretreatment, and LLW concentration. Additional benefits of this scheme might result from using HLW and LLW disposal forms other than glass and grout, but such departures from the reference case are not included at this time. The evaluation of this aggressive separations scheme addressed institutional issues such as: radioactivity remaining in the Hanford Site LLW grout, volume of HLW glass that must be shipped offsite, and disposition of appropriate waste constituents to nonwaste forms

    This paper discussed Canada's attempt in international negotiations to gain credits for energy exports that may result in greenhouse gas emission reductions in the United States. It examined how well founded this position is from an environmental perspective and in terms of international equity and political reality. The author emphasized that the clean energy export issue does not provide a legitimate reason to delay Canada's ratification of the Kyoto Protocol, and cautioned that further renegotiation of Kyoto targets for the first commitment period would not be practical and would jeopardize Canada's international standing. The author did note, however, that for the second commitment period, this issue could be reintroduced. Although the problem can potentially be resolved by granting credits to producers and exempting emissions, it was suggested that the most effective approach would be for countries to factor energy export considerations into their negotiating positions

We find that optimally reactive PC scaffolds provide the cleanest graphene transfers without any annealing, after extensive comparison with optical microscopy, x-ray photoelectron spectroscopy, atomic force microscopy, and scanning tunneling microscopy. Comparatively, films transferred with PLA, PPA, PMMA/PC, and PMMA have a two-fold higher roughness and a five-fold higher chemical doping. Using PC scaffolds, we demonstrate the clean transfer of CVD multilayer graphene, fluorinated graphene, and hexagonal boron nitride. Our annealing free, PC transfers enable the use of atomically-clean nanomaterials in biomolecule encapsulation and flexible electronic applications. (paper)

However, estimates indicate that a 20% increase in capacity is needed over that time to meet the rapidly growing demand. The most common incentives for energy efficiency in the Southeast are loans and rebates; however, total public spending on energy efficiency is limited. The most common state-level policies to support renewable energy development are personal and corporate tax incentives and loans. The region produced 1.8% of the electricity from renewable resources other than conventional hydroelectricity in 2009, half of the national average. There is significant potential for development of a biomass market in the region, as well as use of local wind, solar, methane-to-energy, small hydro, and combined heat and power resources. Options are offered for expanding and strengthening state-level policies such as decoupling, integrated resource planning, building codes, net metering, and interconnection standards to support further clean energy development. Benefits would include energy security, job creation, insurance against price fluctuations, increased value of marginal lands, and local and global environmental paybacks.

    2014-04-01

    Full Text Available Nowadays renewable sources are preferred over the non renewable source to generate the energy. The rapid rates of exhausting non-renewable resources have completed us to look out for new avenues in energy generation. According to global energy scenario, developed countries are adopting renewable resources as major source of energy. Geothermal energy originates from the original formation of the planet, from radioactive decay of minerals, and from solar energy absorbed at the surface. Geothermal energy is derived from the hot interior of the earth. The earth is a reservoir of heat energy, most of which is buried and is observed during episodes of volcanic eruption at the surfaces. Geothermal is one of the most promising renewable source of energy which is plentiful, eco-friendly, reliable and clean source of energy available in earth crust. In our country there is wide scope for the utilization of geothermal energy with proper strategically approach to meet the energy requirement. The future prospects of this heat energy as a sustainable source of renewable energy are indeed promising. Today India is the fifth largest consumer of electricity and by 2030 it will become third largest overtaking Japan and Russia according to statistical data available by Energy Planning Commission, Government of India.

  1. Alternative Enhanced Chemical Cleaning Basic Studies Results FY09

    Energy Technology Data Exchange (ETDEWEB)

    Due to the need to close waste storage tanks, chemical cleaning methods are needed for the effective removal of the heels. Oxalic acid is the preferred cleaning reagent for sludge heel dissolution, particularly for iron-based sludge, due to the strong complexing strength of the oxalate. However, the large quantity of oxalate added to the tank farm from oxalic acid based chemical cleaning has significant downstream impacts. Optimization of the oxalic acid cleaning process can potentially reduce the downstream impacts from chemical cleaning. To optimize oxalic acid usage, a detailed understanding of the chemistry of oxalic acid based sludge dissolution is required. Additionally, other acid systems may be required for specific waste components with low solubility in oxalic acid and as a means to reduce oxalic acid usage in general. Solubility tests were conducted using non-radioactive, pure metal phases known to be the primary phases present in High Level Waste sludge. The metal phases studied included the aluminum phases gibbsite and boehmite and the iron phases magnetite and hematite. Hematite and boehmite are expected to be the most difficult iron and aluminum phases to dissolve. These mineral phases have been identified in both SRS and Hanford High Level Waste sludge. Acids evaluated for dissolution included oxalic, nitric, and sulfuric acids. The results of the solubility tests indicate that oxalic and sulfuric acids are more effective for the dissolution of the primary sludge phases. For boehmite, elevated temperature will be required to promote effective phase dissolution in the acids studied. Literature reviews, thermodynamic modeling, and experimental results have all confirmed that pH control using a supplemental proton source (additional acid) is critical for minimization of oxalic acid usage during the dissolution of hematite. These results emphasize the importance of pH control in optimizing hematite dissolution in oxalic acid and may explain the somewhat

    Coalbed methane (CBM) has the potential to emerge as a significant clean energy resource. It also has the potential to replace other diminishing hydrocarbon reserves. The latest developments in technologies and methodologies are playing a key role in harnessing this unconventional resource. Some of these developments include adaptations of existing technologies used in conventional oil and gas generations, while others include new applications designed specifically to address coal's unique properties. Completion techniques have been developed that cause less damage to the production mechanisms of coal seams, such as those occurring during cementing operations. Stimulation fluids have also been engineered specifically to enhance CBM production. Deep coal deposits that remain inaccessible by conventional mining operations offer CBM development opportunities.

    International Nuclear Information System (INIS)

    The New Brunswick Market Design Committee will address environmental concerns within the context of the new energy policy and market rules for the newly restructured electric power industry. The new rules that come with power restructuring will in some ways facilitate environmental protection but they can also complicate it. With open access markets, it will be possible to coordinate evolving energy frameworks with current environmental objectives. Restructuring provides an opportunity to create incentives and guidelines to operate in an environmentally sustainable manner, as suggested in the New Brunswick Energy Policy, White Paper which outlines green pricing, the development of a provincial Climate Change Action Plan, and promotion of alternative energy. The Market Design Committee examined the environmental concerns listed within the White Paper that pertain to the generation and transmission of electricity. These include the integration of energy and environmental policy. Other issues addressed in this report were trans-boundary and global air emissions, the development of a provincial climate change action plan, and a federal-provincial climate change framework agreement. New Brunswick will encourage the development of pilot studies that demonstrate the benefits of renewable and alternative technologies and that help promote the market to manufacture, sell and maintain renewable and alternative technologies in small-scale on-site power generation. This report also discussed the 4 key air pollutants for which specific treatment has been defined, including sulphur dioxide, nitrogen oxides, mercury and carbon dioxide. Recommendations for reducing these emissions include the use of renewable energy sources, the use of lower carbon fuels, increased efficiency of power transmission/generation/distribution systems, reducing power demand by the industrial sector, and promoting energy efficient building codes. 34 refs., 1 tab

    2010-05-15

    With the depletion of conventional resources and the increasing concerns about the environment, emphasis has been put on developing clean energy. Clean energy is expected to become one of the main industrial sectors within the next decade, thus creating numerous jobs. While significant investments have been made by several countries to shift to clean energy, Canada is investing in highly polluting resources such as the tar sands. It is shown that if Canada were to match U.S. efforts in terms of clean energy on a per person basis, they would need to invest 11 billion additional dollars and this would result in the creation of 66,000 clean energy jobs. This paper showed that Canada is falling behind in terms of clean energy and the authors recommend that the Canadian government match U.S. investments and design policies in support of clean energy and put a price on carbon so as to favor the development of the clean energy sector and its consequent job creation.

SELF is a 501(c)(3) and a certified Community Development Financial Institution (CDFI). SELF is a community-based lending organization that operates the Clean Energy Loan Program, which focuses on improving the overall quality of life of underserved populations in Florida with an emphasis on home energy improvements and cost-effective renewable energy alternatives. SELF was launched in 2010 through the creation of the non-profit organization and with a $2.9 million Energy Efficiency and Conservation Block (EECBG) grant from the U.S. Department of Energy (DOE). SELF has its main office and headquarters in St. Lucie County, in the region known as the Treasure Coast in East-Central Florida. St. Lucie County received funding to create SELF as an independent non-profit institution, outside the control of local government. This was important for SELF to create its identity as an integral part of the business community and to help in its quest to become a Community Development Financial Institution (CDFI). This goal was accomplished in 2013, allowing SELF to focus on its mission to increase energy savings while serving markets that have struggled to find affordable financial assistance. These homeowners are most impacted by high energy costs. Energy costs are a disproportionate percentage of household expenses for low to moderate income (LMI) households. Electricity costs have been steadily rising in Florida by nearly 5% per year. Housing in LMI neighborhoods often includes older inefficient structures that further exacerbate the problem. Despite the many available clean energy solutions, most LMI property owners do not have the disposable income or equity in their homes necessary to afford the high upfront cost

    In an effort to develop and optimize chemical cleaning methods for the removal of sludge heels from High Level Waste tanks, solubility tests have been conducted using nonradioactive, pure metal phases. The metal phases studied included the aluminum phase gibbsite and the iron phases hematite, maghemite, goethite, lepidocrocite, magnetite, and wustite. Many of these mineral phases have been identified in radioactive, High Level Waste sludge at the Savannah River and Hanford Sites. Acids evaluated for dissolution included oxalic, nitric, and sulfuric acids and a variety of other complexing organic acids. The results of the solubility tests indicate that mixtures of oxalic acid with either nitric or sulfuric acid are the most effective cleaning solutions for the dissolution of the primary metal phases in sludge waste. Based on the results, optimized conditions for hematite dissolution in oxalic acid were selected using nitric or sulfuric acid as a supplemental proton source. Electrochemical corrosion studies were also conducted (reported separately; Wiersma, 2010) with oxalic/mineral acid mixtures to evaluate the effects of these solutions on waste tank integrity. The following specific conclusions can be drawn from the test results: (1) Oxalic acid was shown to be superior to all of the other organic acids evaluated in promoting the dissolution of the primary sludge phases. (2) All iron phases showed similar solubility trends in oxalic acid versus pH, with hematite exhibiting the lowest solubility and the slowest dissolution. (3) Greater than 90% hematite dissolution occurred in oxalic/nitric acid mixtures within one week for two hematite sources and within three weeks for a third hematite sample with a larger average particle size. This dissolution rate appears acceptable for waste tank cleaning applications. (4) Stoichiometric dissolution of iron phases in oxalic acid (based on the oxalate concentration) and the formation of the preferred 1:1 Fe to oxalate complex

    In February 2009, the U.S. and Canada established the Clean Energy Dialogue, aiming at identifying ways to reduce greenhouse gases, in order to fight against global warming. This initiative led to the development of an action plan by joint Canada-U.S. working groups that comprise activities in three defined areas: the development of clean energy technology, the construction of a more efficient energy grid, and the expansion of research and development (R&D). The objective is to improve available modes of environmentally responsible energy production, minimize waste in energy transportation and delivery, and set up new alternatives. This document is a study used as a source of information by the working group. It will allow a better understanding of the scientific production, give an overview of the various collaboration and trends around the world in the field of clean energy R&D and in three subfields of interest: future generation biofuels, clean engines/vehicles and energy efficiency homes and buildings. This scientometric study shows that, in clean energy R&D, the U.S. and Canada are among the 15 leading countries. In clean energy R&D and in the three subfields, Canada's strongest affinities are generally with the U.S., Turkey and China. Sweden and Turkey stand out as having levels of impact and specialization that are above the world level. Clean energy R&D is examined as a whole before focusing on scientific activity in future generation biofuels, clean energy vehicles and green buildings. An insight of the relative strengths and weaknesses of Canada and the U.S. in these areas appears within the presented data. Leading Canadian and U.S. research institutions are also considered for a better understanding of their involvement in these fields and to determine those that were the most active in terms of Canada/U.S. cross-border collaborations. 19 tabs., 15 figs.

    This paper presents the results of a joint Westinghouse Hanford Company (Westinghouse Hanford)-Pacific Northwest Laboratory (PNL) study that considered the feasibility of treating radioactive waste before disposal to reduce the inventory of long-lived radionuclides, making the waste more suitable for geologic disposal. The treatment considered here is one in which waste would be chemically separated so that long-lived radionuclides can be treated using specific processes appropriate for the nuclide. The technical feasibility of enhancing repository performance by this type of treatment is considered in this report. A joint Westinghouse Hanford-PNL study group developed a concept called the Clean Use of Reactor Energy (CURE), and evaluated the potential of current technology to reduce the long-lived radionuclide content in waste from the nuclear power industry. The CURE process consists of three components: chemical separation of elements that have significant quantities of long-lived radioisotopes in the waste, exposure in a neutron flux to transmute the radioisotopes to stable nuclides, and packaging of radionuclides that cannot be transmuted easily for storage or geologic disposal. 76 refs., 32 figs., 24 tabs.

    Solubility testing with simulated High Level Waste tank heel solids has been conducted in order to evaluate two alternative chemical cleaning technologies for the dissolution of sludge residuals remaining in the tanks after the exhaustion of mechanical cleaning and sludge washing efforts. Tests were conducted with non-radioactive pure phase metal reagents, binary mixtures of reagents, and a Savannah River Site PUREX heel simulant to determine the effectiveness of an optimized, dilute oxalic/nitric acid cleaning reagent and pure, dilute nitric acid toward dissolving the bulk non-radioactive waste components. A focus of this testing was on minimization of oxalic acid additions during tank cleaning. For comparison purposes, separate samples were also contacted with pure, concentrated oxalic acid which is the current baseline chemical cleaning reagent. In a separate study, solubility tests were conducted with radioactive tank heel simulants using acidic and caustic permanganate-based methods focused on the “targeted” dissolution of actinide species known to be drivers for Savannah River Site tank closure Performance Assessments. Permanganate-based cleaning methods were evaluated prior to and after oxalic acid contact.

    For four years, WWF and Roland Berger have tracked developments in the global clean energy technology (cleantech) sector and ranked countries according to their cleantech sales. The 3rd annual 'Clean Economy, Living Planet' report ranks 40 countries based on the 2011 sales value of the clean energy technology products they manufacture. The report shows that the EU has lost its position to China as the leader in the fast growing global cleantech energy manufacturing sector. However, when cleantech sales are weighted as a percentage of GDP, Denmark and Germany occupied the first and third position globally. Last year the sector's global sales value rose by 10% to almost 200 billion euros, close to the scale of consumer electronics manufacturing. It is projected to overtake oil and gas equipment in the next three years.

    We consider a monopolistic firm producing a good while polluting and using a fossil energy. This firm can adopt a clean technology by incurring an investment cost decreasing exponentially with the adoption date. This clean technology does not pollute and has a lower production cost because it uses a renewable energy. We determine the optimal adoption date for the firm in the cases where it is regulated at each period of time and when it is not regulated. Interestingly, the regulated firm ado...

    This is the Final Technical Report for DOE's Energy Efficiency and Conservation Block Grant, Award No. DE-EE0003813, submitted by St. Lucie County, FL (prime recipient) and the Solar and Energy Loan Fund (SELF), the program's third-party administrator. SELF is a 501(c)(3) and a certified Community Development Financial Institution (CDFI). SELF is a community-based lending organization that operates the Clean Energy Loan Program, which focuses on improving the overall quality of life of underserved populations in Florida with an emphasis on home energy improvements and cost-effective renewable energy alternatives. SELF was launched in 2010 through the creation of the non-profit organization and with a $2.9 million Energy Efficiency and Conservation Block (EECBG) grant from the U.S. Department of Energy (DOE). SELF has its main office and headquarters in St. Lucie County, in the region known as the Treasure Coast in East-Central Florida. St. Lucie County received funding to create SELF as an independent non-profit institution, outside the control of local government. This was important for SELF to create its identity as an integral part of the business community and to help in its quest to become a Community Development Financial Institution (CDFI). This goal was accomplished in 2013, allowing SELF to focus on its mission to increase energy savings while serving markets that have struggled to find affordable financial assistance. These homeowners are most impacted by high energy costs. Energy costs are a disproportionate percentage of household expenses for low to moderate income (LMI) households. Electricity costs have been steadily rising in Florida by nearly 5% per year. Housing in LMI neighborhoods often includes older inefficient structures that further exacerbate the problem. Despite the many available clean energy solutions, most LMI property owners do not have the disposable income or equity in their homes necessary to afford the high upfront cost

  8. REVIEW OF ALTERNATIVE ENHANCED CHEMICAL CLEANING OPTIONS FOR SRS WASTE TANKS

    Energy Technology Data Exchange (ETDEWEB)

    Hay, M.; Koopman, D.

    2009-08-01

    A literature review was conducted to support the Task Technical and Quality Assurance Plan for Alternative Enhanced Chemical Cleaning (AECC) for sludge heel removal funded as part of the EM-21 Engineering and Technology program. The goal was to identify potential technologies or enhancements to the baseline oxalic acid cleaning process for chemically dissolving or mobilizing Savannah River Site (SRS) sludge heels. The issues with the potentially large volume of oxalate solids generated from the baseline process have driven an effort to find an improved or enhanced chemical cleaning technology for the tank heels. This literature review builds on a previous review conducted in 2003. A team was charged with evaluating the information in these reviews and developing recommendations of alternative technologies to pursue. The new information in this report supports the conclusion of the previous review that oxalic acid remains the chemical cleaning agent of choice for dissolving the metal oxides and hydroxides found in sludge heels in carbon steel tanks. The potential negative impact of large volumes of sodium oxalate on downstream processes indicates that the amount of oxalic acid used for chemical cleaning needs to be minimized as much as possible or the oxalic acid must be destroyed prior to pH adjustment in the receipt tank. The most straightforward way of minimizing the volume of oxalic acid needed for chemical cleaning is through more effective mechanical cleaning. Using a mineral acid to adjust the pH of the sludge prior to adding oxalic acid may also help to minimize the volume of oxalic acid used in chemical cleaning. If minimization of oxalic acid proves insufficient in reducing the volume of oxalate salts, several methods were found that could be used for oxalic acid destruction. For some waste tank heels, another acid or even caustic treatment (or pretreatment) might be more appropriate than the baseline oxalic acid cleaning process. Caustic treatment of high

    Technology development in the clean energy and broader clean tech space has proven to be challenging. Long-standing methods for advancing clean energy technologies from science to commercialization are best known for relatively slow, linear progression through research and development, demonstration, and deployment (RDD&D); and characterized by well-known valleys of death for financing. Investment returns expected by traditional venture capital investors have been difficult to achieve, particularly for hardware-centric innovations, and companies that are subject to project finance risks. Commercialization support from incubators and accelerators has helped address these challenges by offering more support services to start-ups; however, more effort is needed to fulfill the desired clean energy future. The emergence of new strategic investors and partners in recent years has opened up innovative opportunities for clean tech entrepreneurs, and novel commercialization models are emerging that involve new alliances among clean energy companies, RDD&D, support systems, and strategic customers. For instance, Wells Fargo and Company (WFC) and the National Renewable Energy Laboratory (NREL) have launched a new technology incubator that supports faster commercialization through a focus on technology development. The incubator combines strategic financing, technology and technical assistance, strategic customer site validation, and ongoing financial support.

  11. Boost matrix converters in clean energy systems

    Science.gov (United States)

    Karaman, Ekrem

    This dissertation describes an investigation of novel power electronic converters, based on the ultra-sparse matrix topology and characterized by the minimum number of semiconductor switches. The Z-source, Quasi Z-source, Series Z-source and Switched-inductor Z-source networks were originally proposed for boosting the output voltage of power electronic inverters. These ideas were extended here on three-phase to three-phase and three-phase to single-phase indirect matrix converters. For the three-phase to three-phase matrix converters, the Z-source networks are placed between the three-switch input rectifier stage and the output six-switch inverter stage. A brief shoot-through state produces the voltage boost. An optimal pulse width modulation technique was developed to achieve high boosting capability and minimum switching losses in the converter. For the three-phase to single-phase matrix converters, those networks are placed similarly. For control purposes, a new modulation technique has been developed. As an example application, the proposed converters constitute a viable alternative to the existing solutions in residential wind-energy systems, where a low-voltage variable-speed generator feeds power to the higher-voltage fixed-frequency grid. Comprehensive analytical derivations and simulation results were carried out to investigate the operation of the proposed converters. Performance of the proposed converters was then compared between each other as well as with conventional converters. The operation of the converters was experimentally validated using a laboratory prototype.

  12. Enhanced understanding of energy ratepayers: Factors influencing perceptions of government energy efficiency subsidies and utility alternative energy use

    International Nuclear Information System (INIS)

    This study explores factors related to energy consumers' perceptions of government subsidies for utility provided energy efficiency (EE) programs and for utility providers' use of more clean/alternative energy sources. Demographic factors, attitudes, planned purchases, and perceptions of utility provider motives in relation to governmental and utility provider EE initiatives (i.e. providing discounts and coupons for CFL bulbs), plus the influence of gain- and loss-framed messages are investigated. Over 2000 respondents completed a 16 item phone survey. Hierarchical regression explained 38% of the variance in reactions regarding government subsidies of the cost of utility provided EE programs and 43% of the variance in perceptions involving whether utility companies should use of more clean or alternative forms of energy. Gender and party differences emerged. Loss-framed messages were more important when the issue was government subsidies. Both gain- and loss-framed messages were important when clean/alternative energy was the issue. - Highlights: • Over 2000 ratepayers were surveyed on their attitudes, planned behaviors and perceptions towards energy efficiency programs. • Almost 40% of how ratepayers feel about government subsidies and utility use of clean/alternative energy was explained. • Loss-framed messages were more effective when the dependent variable was ratepayer perception of government subsidies

    2012-02-22

    This project provides educational opportunities creating both a teaching facility and center for public outreach. The facility is the largest solar array in Nebraska. It was designed to allow students to experience a variety of technologies and provide the public with opportunities for exposure to the implementation of an alternative energy installation designed for an urban setting. The project integrates products from 5 panel manufacturers (including monocrystalline, polycrystalline and thin film technologies) mounted on both fixed and tracking structures. The facility uses both micro and high power inverters. The majority of the system was constructed to serve as an outdoor classroom where panels can be monitored, tested, removed and replaced by students. As an educational facility it primarily serves students in the Creighton University and Metropolitan Community College, but it also provides broader educational opportunities. The project includes a real-time dashboard and a historical database of the output of individual inverters and the corresponding meteorological data for researcher and student use. This allows the evaluation of both panel types and the feasibility of installation types in a region of the country subject to significant temperature, wind and precipitation variation.

  15. Solar energy for buildings: clean energies utilisation and development

    International Nuclear Information System (INIS)

    The move towards a de-carbonized world, driven partly by climate science and partly by the business opportunities it offers, will need the promotion of environmentally friendly alternatives, if an acceptable stabilization level of atmospheric carbon dioxide is to be achieved. This requires the harnessing and use of natural resources that produce no air pollution or greenhouse gases and provides comfortable coexistence of human, livestock, and plants. This article presents a comprehensive review of energy sources, and the development of sustainable technologies to explore these energy sources. It also includes potential renewable energy technologies, efficient energy systems, energy savings techniques and other mitigation measures necessary to reduce climate changes. The article concludes with the technical status of the ground source heat pumps (GSHP) technologies. (full text)

  1. New Air Cleaning Strategies for Reduced Commercial Building Ventilation Energy

    Energy Technology Data Exchange (ETDEWEB)

    Sidheswaran, Meera; Destaillats, Hugo; Sullivan, Douglas P.; Fisk, William J.

    2010-10-27

    Approximately ten percent of the energy consumed in U.S. commercial buildings is used by HVAC systems to condition outdoor ventilation air. Reducing ventilation rates would be a simple and broadly-applicable energy retrofit option, if practical counter measures were available that maintained acceptable concentrations of indoor-generated air pollutants. The two general categories of countermeasures are: 1) indoor pollutant source control, and 2) air cleaning. Although pollutant source control should be used to the degree possible, source control is complicated by the large number and changing nature of indoor pollutant sources. Particle air cleaning is already routinely applied in commercial buildings. Previous calculations indicate that particle filtration consumes only 10percent to 25percent of the energy that would otherwise be required to achieve an equivalent amount of particle removal with ventilation. If cost-effective air cleaning technologies for volatile organic compounds (VOCs) were also available, outdoor air ventilation rates could be reduced substantially and broadly in the commercial building stock to save energy. The research carried out in this project focuses on developing novel VOC air cleaning technologies needed to enable energy-saving reductions in ventilation rates. The minimum required VOC removal efficiency to counteract a 50percent reduction in ventilation rate for air cleaning systems installed in the HVAC supply airstream is modest (generally 20percent or less).

    For decades, America has anticipated the transformational impact of clean energy technologies. But even as costs fell and technology matured, a clean energy revolution always seemed just out of reach. Critics often said a clean energy future would "always be five years away." This report focuses on four technology revolutions that are here today. In the last five years they have achieved dramatic reductions in cost and this has been accompanied by a surge in consumer, industrial and commercial deployment. Although these four technologies still represent a small percentage of their total market, they are growing rapidly. The four key technologies this report focuses on are: onshore wind power, polysilicon photovoltaic modules, LED lighting, and electric vehicles.

  10. Clean energy: Revisiting the challenges of industrial policy

    International Nuclear Information System (INIS)

    Large public investments in clean energy technology arguably constitute an industrial policy. One rationale points to market failures that have not been corrected by other policies, most notably greenhouse gas emissions and dependence on oil. Another inspiration for clean energy policy reflects economic arguments of the 1980s. It suggests strategic government investments would increase U.S. firms' market share of a growing industry and thus help American firms and workers. This paper examines the reasoning for clean energy policy and concludes that: •While a case can be made that subsidizing clean energy might help address market failures, the case may be narrower than some assert, and turning theory into sound practice is no simple feat. •An appropriate price on greenhouse gases is an essential precondition to ensuring efficient incentives to develop and deploy cost-effective emissions-abating technologies. However, efficient prices alone are unlikely to generate efficient levels of basic research and development by private firms. •Government investments in clean energy are unlikely to produce net increases in employment in the long run, in part because pushing home-grown technologies at taxpayers' expense offers no guarantee that the eventual products ultimately would not be manufactured somewhere else. •Spending on clean energy technologies is not well suited to fiscal stimulus. The authors recommend that: •Federal energy spending should invest in technologies with the lowest expected cost of abatement and highest probability of market penetration. •Funding decisions ought to be insulated – as much as possible – from rent-seeking by interest groups, purely political distortions, and the parochial preferences of legislators. - Highlights: ► Clean energy technology policy may be less justifiable than many assert, and doing it well is hard. ► The government should appropriately price greenhouse gas emissions and fund technology R and D.

    2011-02-15

    Clean Cities is a government-industry partnership sponsored by the U.S. Department of Energy's (DOE) Vehicle Technologies Program, which is part of the Office of Energy Efficiency and Renewable Energy. Working with its network of about 100 local coalitions and more than 6,500 stakeholders across the country, Clean Cities delivers on its mission to reduce petroleum consumption in on-road transportation. In its work to reduce petroleum use, Clean Cities focuses on a portfolio of technologies that includes electric drive, propane, natural gas, renewable natural gas/biomethane, ethanol/E85, biodiesel/B20 and higher-level blends, fuel economy, and idle reduction. Over the past 17 years, Clean Cities coalitions have displaced more than 2.4 billion gallons of petroleum; they are on track to displace 2.5 billion gallons of gasoline per year by 2020. This Clean Cities Strategic Plan lays out an aggressive five-year agenda to help DOE Clean Cities and its network of coalitions and stakeholders accelerate the deployment of alternative fuel and advanced technology vehicles, while also expanding the supporting infrastructure to reduce petroleum use. Today, Clean Cities has a far larger opportunity to make an impact than at any time in its history because of its unprecedented $300 million allocation for community-based deployment projects from the American Recovery and Reinvestment Act (ARRA) (see box below). Moreover, the Clean Cities annual budget has risen to $25 million for FY2010 and $35 million has been requested for FY2011. Designed as a living document, this strategic plan is grounded in the understanding that priorities will change annually as evolving technical, political, economic, business, and social considerations are woven into project decisions and funding allocations. The plan does not intend to lock Clean Cities into pathways that cannot change. Instead, with technology deployment at its core, the plan serves as a guide for decision-making at both the

    Innovative approaches are needed to address the needs of the 1.3 billion people lacking electricity, while simultaneously transitioning to a decarbonized energy system. With particular focus on the energy needs of the underserved, we present an analytic and conceptual framework that clarifies the heterogeneous continuum of centralized on-grid electricity, autonomous mini- or community grids, and distributed, individual energy services. A historical analysis shows that the present day is a unique moment in the history of electrification where decentralized energy networks are rapidly spreading, based on super-efficient end-use appliances and low-cost photovoltaics. We document how this evolution is supported by critical and widely available information technologies, particularly mobile phones and virtual financial services. These disruptive technology systems can rapidly increase access to basic electricity services and directly inform the emerging Sustainable Development Goals for quality of life, while simultaneously driving action towards low-carbon, Earth-sustaining, inclusive energy systems.

    A literature review was conducted to support the Task Technical and Quality Assurance Plan for Alternative Enhanced Chemical Cleaning (AECC) for sludge heel removal funded as part of the EM-21 Engineering and Technology program. The goal was to identify potential technologies or enhancements to the baseline oxalic acid cleaning process for chemically dissolving or mobilizing Savannah River Site (SRS) sludge heels. The issues with the potentially large volume of oxalate solids generated from the baseline process have driven an effort to find an improved or enhanced chemical cleaning technology for the tank heels. This literature review builds on a previous review conducted in 2003. A team was charged with evaluating the information in these reviews and developing recommendations of alternative technologies to pursue. The new information in this report supports the conclusion of the previous review that oxalic acid remains the chemical cleaning agent of choice for dissolving the metal oxides and hydroxides found in sludge heels in carbon steel tanks. The potential negative impact of large volumes of sodium oxalate on downstream processes indicates that the amount of oxalic acid used for chemical cleaning needs to be minimized as much as possible or the oxalic acid must be destroyed prior to pH adjustment in the receipt tank. The most straightforward way of minimizing the volume of oxalic acid needed for chemical cleaning is through more effective mechanical cleaning. Using a mineral acid to adjust the pH of the sludge prior to adding oxalic acid may also help to minimize the volume of oxalic acid used in chemical cleaning. If minimization of oxalic acid proves insufficient in reducing the volume of oxalate salts, several methods were found that could be used for oxalic acid destruction. For some waste tank heels, another acid or even caustic treatment (or pretreatment) might be more appropriate than the baseline oxalic acid cleaning process. Caustic treatment of high

    Full Text Available This paper analyzes the current situation in the sphere of alternative energy engineering in Russia. On the one hand, the national economy and the population in general do not have problems with energy supply and Russia in general is the world's largest exporter of energy. On the other hand, centralized energy supply covers only one third of its territory and two-thirds are in the area of decentralized and autonomous power supply. In the current situation, energy sources that are independent of centralized networks based on clean technologies are a promising alternative. The paper assesses the current state of alternative energy development in the world and in Russia, its potential and prospects. It was found out that development and qualitative improvement of the regulatory framework should have priority for alternative energy mastering in Russia as well as active joint action of government, business and civic leaders to gradually consolidate in public consciousness and behaviour of a new culture of energy consumption based on the rules of economy and environmental safety. The analysis of the proposals for the development of alternative energy industries in Russia was made. Particular attention is paid to energy saving experience and energy efficiency in housing services and public utilities. Questions on the creation and development of formal and informal institutions of non-conventional energy sources usage are asked.

    Full Text Available In many countries of the world investments are made for obtaining energy efficiency, pursuing to increase the generation of non-polluting fuels due to the fact that energy is vital for any economy. The increase in non-polluting fuels and in renewable energy generation might lead to diminishing the dependence of countries less endowed with conventional energy resources on oil and natural gas from Russia or from Arab countries. Nevertheless, environmental issues represent serious questions facing the mankind, requiring the identification, prevention, and why not, their total solving.European Union countries depend on imports of energy, especially on oil imports. At the same time, the European Union countries record a high volume of greenhouse gas emissions, substances adding to global warming. The transport sector is the main consumer of fossil fuels and generator of greenhouse gas emissions. Therefore, diversifying the energy supply used in the transport sector with less polluting sources is an essential objective of the European Union policy in the transport, energy and environment sector. Road transports’ is the sector recording the highest consumption of energy and the highest volume of greenhouse gas emissions.The use of ecologic fuels in the transport sector is an important factor for achieving the objectives of European policies in the field. It is yet to be seen to what extent alternative energy sources are damaging to the environment, as it is a known fact that even for them is recorded a certain level of negative externalities.

    The primary objective of this study is to develop representative indications of the relative energy use, associated CO2 emissions, and total equivalent warming impact (TEWI) of viable options to replace CFCs in their major energy-related application areas. It was motivated, in part, by a concern that most attention to date has focused on the DIRECT global warming effect of CFC's and their alternatives, with adequate attention being paid to the INDIRECT effect of the CO2 emissions arising from the differences in energy consumption by systems using different alternatives. The DIRECT and INDIRECT contributions are combined in this analysis to determine the TEWI of the various technical options. The study is international in scope and takes into account significant differences in present CFC end-use practices, sources of energy, and other societal factors between Europe, Japan, and North America. This study should be considered an overview of key issues.

    The direct carbon fuel cell technology provides excellent conditions for conversion of chemical energy of carbon-containing solid fuels directly into electricity. The technology is very promising since it is relatively simple compared to other fuel cell technologies and accepts all carbon-reach substances as possible fuels. Furthermore, it makes possible to use atmospheric oxygen as the oxidizer. In this paper the results of authors' recent investigations focused on analysis of the performance of a direct carbon fuel cell supplied with graphite, granulated carbonized biomass (biocarbon), and granulated hard coal are presented. The comparison of the voltage-current characteristics indicated that the results obtained for the case when the cell was operated with carbonized biomass and hard coal were much more promising than those obtained for graphite. The effects of fuel type and the surface area of the cathode on operation performance of the fuel cell were also discussed.

    Metal hydrides are a fascinating class of materials that can be utilized for a surprising variety of clean energy applications, including smart solar collectors, smart windows, sensors, thermal energy storage, and batteries, in addition to their traditional application for hydrogen storage. Over the past decade, research on metal hydrides for hydrogen storage increased due to global governmental incentives and an increased focus on hydrogen storage research for polymer electrolyte membrane fuel cell operation. Tremendous progress has been made in so-called complex metal hydrides for hydrogen storage applications with the discovery of many new hydrides containing covalently bound complex anions. Many of these materials have applications beyond hydrogen storage and are being investigated for lithium-ion battery separator and anode materials. In this issue of MRS Bulletin , we present the state of the art of key evolving metal-hydride-based clean energy technologies with an outlook toward future needs.

  19. Metal oxide electrocatalysts for alternative energy technologies

    Pacquette, Adele Lawren

    This dissertation focuses on the development of metal oxide electrocatalysts with varying applications for alternative energy technologies. Interest in utilizing clean, renewable and sustainable sources of energy for powering the planet in the future has received much attention. This will address the growing concern of the need to reduce our dependence on fossil fuels. The facile synthesis of metal oxides from earth abundant metals was explored in this work. The electrocatalysts can be incorporated into photoelectrochemical devices, fuel cells, and other energy storage devices. The first section addresses the utilization of semiconductors that can harness solar energy for water splitting to generate hydrogen. An oxysulfide was studied in order to combine the advantageous properties of the stability of metal oxides and the visible light absorbance of metal chalcogenides. Bi 2O2S was synthesized under facile hydrothermal conditions. The band gap of Bi2O2S was smaller than that of its oxide counterpart, Bi2O3. Light absorption by Bi 2O2S was extended to the visible region (>600 nm) in comparison to Bi2O3. The formation of a composite with In 2O3 was formed in order to create a UV irradiation protective coating of the Bi2O2S. The Bi2O2S/In 2O3 composite coupled with a dye CrTPP(Cl) and cocatalysts Pt and Co3O4 was utilized for water splitting under light irradiation to generate hydrogen and oxygen. The second section focuses on improving the stability and light absorption of semiconductors by changing the shapes and morphologies. One of the limitations of semiconductor materials is that recombination of electron-hole pairs occur within the bulk of the materials instead of migration to the surface. Three-dimensional shapes, such as nanorods, can prevent this recombination in comparison to spherical particles. Hierarchical structures, such as dendrites, cubes, and multipods, were synthesized under hydrothermal conditions, in order to reduce recombination and improve

    Full Text Available Effective institutional arrangements at local and national levels are important for promotion of renewable energy in a country. The present study attempts to examine the institutional arrangements for development of domestic clean energy in rural northwest Pakistan. The survey data were collected from 100 randomly selected households in District Swat in northwest Pakistan. The data were analyzed using descriptive statistics and Chi-Square test was applied wherever needed. The study describes that very limited number of public and private organizations were working on CD (Clean Development in the area. Surprisingly, no institutional arrangements exclusively meant for domestic clean energy promotion were observed in the area. The study concludes that the objectives of Kyoto Protocol in Pakistan can be achieved only if the government and NGOs (Non-Governmental Organizations work together to initiate cost-effective renewable energy interventions, particularly in rural areas. This will not only improve the socioeconomic and environmental conditions in the local context, but will play a key role in achieving the SDGs (Sustainable Development Goals of the United Nation?s post-2015 development agenda.

  3. Environmental impacts of energy alternatives

    International Nuclear Information System (INIS)

    Indian society today is concerned about the health and environmental risks of technologies. The major environmental issues of concern for technologies available for electricity generation are air emissions, management of wastes generated and land requirements. The production of electricity in India is primarily composed of a mix of thermal and hydroelectric power plants with nuclear energy currently contributing to an extent of slightly above 2.0%. For maintaining a decent living standard the present electricity generation has to be increased manifold and with the existing commercially available technologies this can lead to a greater impact on the environment in the immediate vicinity of plant unless a judicious mix is chosen. India which hardly contributed 1 of the global pollution in the year 1950 contributes about 20% now and with the growth in electricity generation its contribution will also be slightly increasing and hence environment will have to be one of the guiding factors in future choice of technologies for the growth of electric power generation. Indian coal has a very high ash content (30 - 50 %) and hence the fly ash problem in India can be severe. During the year 1993-94 approximately 33 million tonnes of fly ash was generated in India from the coal fired thermal power stations. The land requirement for disposal of this ash is continuously increasing. The disposal of fly ash near water bodies will also create difficulties as in addition to radionuclides, toxic trace elements may also get washed out. Pollution from the use of coal will have a definite effect on the environment in addition to depletion of the energy source

  4. Rare Earths and Clean Energy: analyzing China's upper hand

    International Nuclear Information System (INIS)

    An ominous but avoidable resource crunch in the so-called 'rare earth elements' is now threatening the development of a number of key industries from energy to defense to consumer electronics. As key components in the latest generation of technologies, including specialized magnets for windmills and hybrid cars, lasers for range finders and 'smart' munitions, and phosphors for LCD screens, demand for these rare metals is expected to grow rapidly in the years to come. But decades of under-investment in the mining and separation of these elements across the globe has left the industry ill-prepared to meet thi s growing demand. Over the years, only China has recognized the strategic significance of these resources and has succeeded in gaining a near monopoly on production, currently churning out 97% of the world' s rare earth oxides. Faced with problems of its own, and eager to use its resource advantage to master higher levels of value-added production of rare earth-dependent products, China has increasingly limited the rest of the world's access to these raw materials. This only complicates what was already projected to be a problematic resource shortage. This issue demands a higher quality of public debate. Rare earth consuming countries outside of China have only recently become aware of their dependence and started to take stock of the risks. Time is of the essence. Bringing new supplies online to meet growing demand is a long, complicated and risky process but is nevertheless necessary to ensure the development of high tech industries, notably clean energy. Accessible reserves of rare earths do exist outside of China and mitigating the effects of the looming shortage requires opening up these reserves to production. Yet, as the Chinese experience attests, there are substantial risks to the environment associated with mining and separating rare earths. Care must be taken to ensure responsible mining practices across the globe. Longer-term solutions, such as

    2015-03-01

    Full Text Available Given the overwhelming scientific evidence on climate change, voluntary reduction of greenhouse gas emissions is becoming increasingly important, especially as diplomatic efforts to secure the commitment of United Nations has proven ineffective. Brazil believes its energy matrix is sufficiently renewable and clean. This may be the reason why there aren’t more official efforts to certify reduced emissions due to the use of clean energy sources. Nevertheless, there are financial incentives for using clean energy sources.  In order to avoid the misuse of financial incentives, the electricity regulator in Brazil has developed strict oversight methodology. However, there is no data on avoided emissions. Herein we propose methodology to certify GHG emission reductions using governance best principles. This methodology is based on official data, calculates the emissions avoided and the equivalent reforestation required to produce the same effect, thus making the results tangible for a less specialized audience. We also describe our practical experience with 120 consuming units that add up to over 1,500 GWh/year.

  7. Clean air and energy: from conflict to reconciliation

    International Nuclear Information System (INIS)

    Unconstrained energy resource development in the Rocky Mountain west is likely to threaten the environment and the health and well-being of the people. Impacts may be associated with visibility degradation, toxic concentrations of gases, and deposition of acidic or toxic substances. Because the possible benefits of energy development in the region are very large, there is great concern that constraints imposed by air quality regulation may preclude the use of important resources or make unduly expensive energy produced from the region. The conflict between energy and clean air in the region is exacerbated by non-energy sources, such as copper smelters and urban areas, that already pose significant environmental threats. The hard policy question is not how to preserve clean air resources or how to develop energy but how to achieve and balance both goals. The effects and regulatory costs and benefits of air pollution control are discussed, and policy directions to protect air quality while pursuing energy development are presented

    Low-carbon energy innovation is essential to combat climate change, promote economic competitiveness, and achieve energy security. Using U.S. patent data and additional patent-relevant data collected from the Internet, we map the landscape of low-carbon energy innovation in the United States since 1975. We isolate 10,603 renewable and 10,442 traditional energy patents and develop a database that characterizes proxy measures for technical and commercial impact, as measured by patent citations and Web presence, respectively. Regression models and multivariate simulations are used to compare the social, institutional, and geographic drivers of breakthrough clean energy innovation. Results indicate statistically significant effects of social, institutional, and geographic variables on technical and commercial impacts of patents and unique innovation trends between different energy technologies. We observe important differences between patent citations and Web presence of licensed and unlicensed patents, indicating the potential utility of using screened Web hits as a measure of commercial importance. We offer hypotheses for these revealed differences and suggest a research agenda with which to test these hypotheses. These preliminary findings indicate that leveraging empirical insights to better target research expenditures would augment the speed and scale of innovation and deployment of clean energy technologies.

    ECAS compared various advanced energy conversion systems that can use coal or coal-derived fuels for baseload electric power generation. It was conducted in two phases. Phase 1 consisted of parametric studies. From these results, 11 concepts were selected for further study in Phase 2. For each of the Phase 2 systems and a common set of ground rules, performance, cost, environmental intrusion, and natural resource requirements were estimated. In addition, the contractors defined the state of the associated technology, identified the advances required, prepared preliminary research and development plans, and assessed other factors that would affect the implementation of each type of powerplant. The systems studied in Phase 2 include steam systems with atmospheric- and pressurized-fluidized-bed boilers; combined cycle gas turbine/steam systems with integrated gasifiers or fired by a semiclean, coal derived fuel; a potassium/steam system with a pressurized-fluidized-bed boiler; a closed-cycle gas turbine/organic system with a high-temperature, atmospheric-fluidized-bed furnace; a direct-coal-fired, open- cycle magnetohydrodynamic/steam system; and a molten-carbonate fuel cell/steam system with an integrated gasifier. The sensitivity of the results to changes in the ground rules and the impact of uncertainties in capital cost estimates were also examined.

The report highlights that while clean energy technology deployment has made steady progress and energy efficiency improvements have been made, continued reliance on fossil fuels to meet growth in global energy demand presents a significant challenge. Scaling-up the deployment of renewable energy, in addition to improving end-use efficiency, enhancing the efficiency of fossil fuel based power generation, and supporting the widespread deployment of CCS will, therefore, also be crucial aspects of the transition to a cleaner energy future. Because the G-20 group of countries represent close to 80% of energy-related CO2 emissions, by developing and deploying energy efficiency and clean energy technologies, they are presented with a unique opportunity to make collective progress in transitioning the global energy system. IEA Deputy Executive Director Richard Jones emphasised the importance of G-20 efforts, saying, 'The IEA welcomes this important collaboration with the G-20. Enhanced deployment of clean energy technologies and of energy efficiency improvements offers energy security and environmental benefits. It will also enable cost savings over the medium and long term -- an aspect that is particularly relevant at a time of economic uncertainty. We believe that enhanced policy assessment and analysis, building on this initial report, will enable governments to take more cost effective and efficient policy decisions.' This report was issued on the authority of the IEA Executive Director, it does not necessarily represent the views of IEA Member countries or the G20.

  15. Ethanol as an alternative source of energy

    International Nuclear Information System (INIS)

    Pakistan, at present facades huge shortage of energy that has disabled several industries and has worsened the living standards of a common man. Its economy mainly depends upon agriculture but relies heavily on imported petroleum to meet the necessities. The importance of national resources as an alternative energy resource is thus greatly felt. The sugar cane industry of Pakistan holds a potential to provide such an alternative fuel as bio ethanol that can be produced entirely from molasses. This paper looks deeper into scope of ethanol as one replacement that can reduce the financial and environmental cost of petroleum based fuels. (author)

    Hydroelectric energy has been in recent times placed as an important future source of renewable and clean energy. The advantage of hydropower as a renewable energy is that it produces negligible amounts of greenhouse gases, it stores large amounts of electricity at low cost and it can be adjusted to meet consumer demand. This noble vision however is becoming more challenging due to rapid urbanization development and increasing human activities surrounding the catchment area. Numerous studies have shown that there are several contributing factors that lead towards the loss of live storage in reservoir, namely geology, ground slopes, climate, drainage density and human activities. Sediment deposition in the reservoir particularly for hydroelectric purposes has several major concerns due to the reduced water storage volume which includes increase in the risk of flooding downstream which directly effects the safety of human population and properties, contributes to economic losses not only in revenue for power generation but also large capital and maintenance cost for reservoir restorations works. In the event of functional loss of capabilities of a hydropower reservoir as a result of sedimentation or siltation could lead to both economical and environmental impact. The objective of this paper is aimed present the importance of hydropower as a source of renewable and clean energy in the national energy mix and the increasing challenges of sustainability.

    2015-11-01

    Full Text Available Water management has recently become a major concern for many countries. During the last century consumption of water and energy has been increased in the world. This trend is anticipated to continue in the decades to come. One of the greatest reasons is the unplanned industrial activities deteriorating environment in the name of rising standard of life. What is needed is the avoidance of environmental pollution and maintenance of natural balance, in the context of sustainable development. However, Turkey’s geographical location has several advantages for extensive use of most of the renewable energy resources. There is a large variation in annual precipitation, evaporation and surface run-off parameters, in Turkey. Precipitation is not evenly distributed in time and space throughout the country. There are 25 hydrological basins in Turkey. But the rivers often have irregular regimes. In this situation the main aim is to manage and use the water resources for renewable, sustainable and clean energy. This paper deals with water management for renewable, sustainable and clean energy in Turkey.

The model explicitly allows for the interaction and substitution between fossil fuels, defined as a non-renewable resource derived from some fixed initial stock, and alternative energy, defined as renewable resource whose production requires capital input. The dynamics of the model depict a unique balance growth to a saddle point. The consumption path temporarily peaks, when fossil fuels are plentif...

  1. An assessment of alternatives for replacing Freon 113 in bench type electrical circuit board cleaning at Fermi National Accelerator Laboratory

    International Nuclear Information System (INIS)

    Fermilab is presently phasing out all solvents containing Freon-113 (CFC-113) as part of the continuing Waste Minimization Program. These solvents are used primarily in cleaning the flux off of electronic circuit boards after soldering, specifically in bench type work. Title VI of the Clean Air Act mandates a production phase-out for ozone depleting substances, like CFC-113, by the year 2000. Our study addresses this issue by evaluating and choosing alternative non-CFC solvents to replace the CFC-1 13 solvents at Fermilab. Several potential non-CFC cleaning solvents were tested. The evaluation took place in three parts: controlled experimental evaluation, chemical composition evaluation, and employee performed evaluation. First, we performed a controlled nine-step procedure with the potential solvents where each was evaluated in categories such as cleaning effectiveness, odor, residue, type of output and drying time. Next, we listed the chemical composition of each solvent. We noted which solvents contained hydrochlorofluorocarbons because they are targeted for phase-out in the future and will be recognized as interim solutions only. Finally, after preliminary testing, five solvents were chosen as the best options. These solvents were sent to be tested by Fermilab employees who use such materials. Their opinions are valuable not only because they are knowledgeable in this field, but also because they will be using the solvents chosen to replace the CFC-113 solvents. The results favored two ''best alternatives'': Safezone Solvent Flux Remover by Miller-Stephenson and E-Series CFC Free Flux-Off 2000 by Chemtech. Another possible solution also pursued is the no-clean solder option. In our study, we were not able to thoroughly investigate the many types of no-clean solders because of time and financial constraints. The testing that was done, however, showed that no-clean solder was a viable alternative in many cases

  2. Cleaning the air with renewable energy : briefing note

    International Nuclear Information System (INIS)

    The Clean Air Renewable Energy Coalition promotes the development of the renewable energy industry in Canada. It acknowledges the effort that the Canadian government has taken to advance investment in renewable energy, but the Coalition is concerned that these investments alone will not achieve the desired objectives without additional policy development by federal, provincial and territorial governments. This report presents an overview of 7 proposals designed to promote and advance renewable energy in Canada. The benefits of these proposals include cleaner air, improved health, engaging public and industry participation in climate change initiatives, and fostering innovation and entrepreneurship in the sector. Brief details were presented for the following 7 proposals: (1) establish a national low-impact renewable energy target for Canada, (2) increase the Wind Power Production Incentive (WPPI) to 2.7 cent per kilowatt hour to ensure appropriate investment in wind energy and harmonization with the United States, (3) extend incentive programs similar to the WPPI to other renewable energy technologies, (4) work with other levels of government to implement policy mechanisms to meet the recommended national renewable energy target, (5) expand the Market Incentive Program (MIP) funding to 30 million dollars per year to 2012 and consult with the provinces and territories to develop a broad-based consumer green energy rebate and education program, (6) identify mechanisms to ensure a meaningful role for renewable energy to contribute to the country's climate change strategy, and (7) develop a Wind Energy Mapping and Wind Measurement Initiative. In a recent update, the Coalition states that low environmental impact renewable energy needs market recognition for its environmental and social benefits. In general, these benefits are not financially valued in energy market pricing. In addition, energy sources that impact significantly on the environment are not financially

  4. Barriers to clean development mechanism renewable energy projects in Mexico

    International Nuclear Information System (INIS)

    Mexico is not reaching its full potential to capture benefits from clean development mechanism (CDM) projects because of its limited market for independent power producers (IPPs) and the barriers imposed on these entities by the state-run electric utility that controls most of the country's generation and transmission. This state-run entity has pursued CDM revenues only in isolated cases where international financial assistance was given because it is bound by law to pursue the least-cost generation option for its customers. Recent changes in Mexican legislation that provide incentives for renewable energy development could open the marketplace for these types of projects. (author)

    Global energy demand is increasing rapidly and due to intensive consumption of different forms of fuels, there are increasing concerns over the reduction in readily available conventional energy resources. Because of the deleterious atmospheric effects of fossil fuels and the uncertainties of future energy supplies, there is a surge of interest to find environmentally friendly alternative energy sources. Hydrogen (H2) has attracted worldwide attention as a secondary energy carrier, since it is the lightest carbon-neutral fuel rich in energy per unit mass and easy to store. Several methods and technologies have been developed for H2 production, but none of them are able to replace the traditional combustion fuel used in automobiles so far. Extensively modified and renovated methods and technologies are required to introduce H2 as an alternative efficient, clean, and cost-effective future fuel. Among several emerging renewable energy technologies, photobiological H2 production by oxygenic photosynthetic microbes such as green algae and cyanobacteria or by artificial photosynthesis has attracted significant interest. In this short review, we summarize the recent progress and challenges in H2-based energy production by means of biological and artificial photosynthesis routes. PMID:25899392

    Hay, M; King, W; Martino, C

    2009-12-18

    Preliminary studies in the EM-21 Alternative Chemical Cleaning Program have focused on understanding the dissolution of Hematite (a primary sludge heel phase) in oxalic acid, with a focus on minimizing oxalic acid usage. Literature reviews, thermodynamic modeling, and experimental results have all confirmed that pH control, preferably using a supplemental proton source, is critical to oxalate minimization. With pH control, iron concentrations as high as 0.103 M have been obtained in 0.11 M oxalic acid. This is consistent with the formation of a 1:1 (iron:oxalate) complex. The solubility of Hematite in oxalic acid has been confirmed to increase by a factor of 3 when the final solution pH decreases from 5 to below 1. This is consistent with literature predictions of a shift in speciation from a 1:3 to 1:1 as the pH is lowered. Above a solution pH of 6, little Hematite dissolves. These results emphasize the importance of pH control in optimizing Hematite dissolution in oxalic acid.

    1994-12-01

    As part of the Strategic Environmental Research and Development Program (SERDP) a clean, agile manufacturing of explosives, propellants and pyrotechniques (CANPEP) effort set about to identify new approaches to materials and processes for producing propellants, explosives and pyrotechniques (PEP). The RDX based explosive PBXN-109 and gun propellant M-43 were identified as candidates for which waste minimization and recycling modifications might be implemented in a short time frame. The binders, additives and plasticizers subgroup identified cast non-curable thermoplastic elastomer (TPE) formulations as possible replacement candidates for these formulations. Paste extrudable explosives were also suggested as viable alternatives to PBXN-109. Commercial inert and energetic TPEs are reviewed. Biodegradable and hydrolyzable binders are discussed. The applicability of various types of explosive formulations are reviewed and some issues associated with implementation of recyclable formulations are identified. It is clear that some processing and weaponization modifications will need to be made if any of these approaches are to be implemented. The major advantages of formulations suggested here over PBXN-109 and M-43 is their reuse/recyclability. Formulations using TPE or Paste could by recovered from a generic bomb or propellant and reused if they met specification or easily reprocessed and sold to the mining industry.

    Predictions are made concerning the development of alternative energy sources in the light of the present national energy situation. Particular emphasis is given to the impact of alternative fuels development on aviation fuels. The future outlook for aircraft fuels is that for the near term, there possibly will be no major fuel changes, but minor specification changes may be possible if supplies decrease. In the midterm, a broad cut fuel may be used if current development efforts are successful. As synfuel production levels increase beyond the 1990's there may be some mixtures of petroleum-based and synfuel products with the possibility of some shale distillate and indirect coal liquefaction products near the year 2000.

For many of the organizations tapped to administer these funds, however, this is a relatively new role that presents the challenge of using public funds in the most effective and innovative fashion possible. Fortunately, each state is not alone in its efforts; many other U.S. states and a number of countries are undertaking similar efforts. Early lessons are beginning to be learned by clean energy funds about how to effectively target public funds towards creating and building renewable energy markets. A number of innovative programs have already been developed that show significant leadership by U.S. states in supporting renewable energy. It is important that clean energy fund administrators learn from this emerging experience.

    The issue of the sustainability of energy supply has attracted worldwide concern given the rapid depletion of fossil energy sources amid increasingly worsening environmental pollution and the drive to develop alternative, environment-friendly, renewable energy sources and energy carriers to secure our energy supply and sustainable development. Hydrogen is considered to be among the best solutions available, although technical barriers, in particular effective hydrogen storage, need to be dealt with. Quasi-one-dimensional carbon nanotubes (CNTs) with rich nanosized pore structures are considered to be a potential hydrogen storage medium; however, controversy over and discrepancies in both the experimental and theoretical results do exist. Therefore, the latest research progress in and the current situation pertaining to hydrogen storage in CNTs are reviewed and discussed in detail. Moreover, CNTs can have wide applications as alternative energy storage media, utilizing fully their unique structural characteristics. We summarize and analyse the advantages as well as the research progress made in using CNTs as electrode materials in lithium-ion batteries and supercapacitors. Further, future applications of CNTs in the energy storage field are explored.

  6. Making Clean Energy with a Kerr Black Hole

    CERN Document Server

    Li, L X

    2000-01-01

    In this paper we present a model for making clean energy with a Kerr black hole. Consider a Kerr black hole with a dense plasma torus spinning around it. A toroidal electric current flows on the surface of the torus, which generates a poloidal magnetic field outside the torus. On the surface of the tours the magnetic field is parallel to the surface. The closed magnetic field lines winding around the torus compress and confine the plasma in the torus, as in the case of tokamaks. Though it is unclear if such a model is stable, we look into the consequences if the model is stable. If the magnetic field is strong enough, the baryonic contamination from the plasma in the torus is greatly suppressed by the magnetic confinement and a clean magnetosphere of electron-positron pairs is built up around the black hole. Since there are no open magnetic field lines threading the torus and no accretion, the power of the torus is zero.

    International Nuclear Information System (INIS)

    Algal Turfs and Algal Turf Scrubbers (ATS) Algal Turfs are bio diverse communities of unicellular to filamentous algae of all major algal phyla. Algal Turf Scrubbers (ATS) are bioengineered ecosystems dominated by algal turfs. They clean water to very high quality, and remove CO2 from the atmosphere by capturing solar energy at rates 10 times that of agriculture and 50 times that of forestry. ATS was invented at the Smithsonian Institution, by scientist, Walter Adey in the 1980s as a tool for controlling water quality in highly diverse model ecosystems. The technology received extensive R and D for aqua cultural, municipal, and industrial water cleaning by Dr. Adey, using venture capital, through the 1990s. Later, Hydro Mentia, Inc., of Ocala, Florida, engineered ATS to landscape scale of 20-50 Mgpd (it is important to note that this is a modular system, capable of expanding to any size.) A 2005 independent study of ATS, by the South Florida Water Management District and the IFAS Institute of the University of Florida, certified ATS as 5-100 times more cost efficient at removing nutrients from Everglades canal waters than the next competitor, the STA, a managed marsh system. ATS and STA were the final contestants in a 15-year study of nine technologies, and ATS was the only technology that created a use able byproduct.

    The paper features a basic outline of the situation in the energy sector of the Czech Republic. It brings information about the current state of the country's energy mix and indicative targets of the State Energy Policy. Though coal and nuclear energy will remain the country's energy staples, great stress is also put on the growth of share of renewable and alternative energy sources. Out of these, the greatest potential in the Czech Republic is that of biomass and waste. To make the use of these sources cost-effective, it is necessary to put stress on heat and power cogeneration.

    Between 2010 and 2013, the U.S. Department of Energy (DOE) funded the Southeast Clean Energy Application Center (SE-CEAC), co-located at the North Carolina Solar Center at NC State University (NCSU) and at Mississippi State University. The SE-CEAC was one of eight regional CEACs established to promote and assist in transforming the market for combined heat and power (CHP), district energy (DE) and waste heat to power (WHP) throughout the U.S. CHP locates power generation at the point of demand and makes productive use of the residual thermal energy for process and space heating in factories and businesses, thus lowering the cost of meeting electricity and heat requirements and increasing energy efficiency. The overall goal of the SE-CEAC was to support end-user implementation and overall market transformation for CHP and related clean energy technologies. Five objectives were targeted to achieve the goal: 1. Market Analysis and Information Dissemination 2. Outreach and Education for Potential CHP End-users 3. Policy Support for State and Regional Stakeholders 4. Technical Assistance to Support CHP Deployment 5. Collaboration with DOE and other CEACs Throughout the project, the CEACs provided key services of education and outreach, technical assistance and market analysis in support of project objectives. These services were very effective at achieving key objectives of assisting prospective CHP end-users and informing policy makers, utilities and others about the benefits of CHP. There is a marked increase in the awareness of CHP technologies and applications as an energy resource among end-users, policymakers, utility regulators, electric utilities and natural gas utilities in the Southeast region as a result. At the end of 2013, a number of best-practice policies for CHP were applied or under consideration in various Southeast states. The SE-CEAC met its targets for providing technical assistance with over 50 analyses delivered for 412 MW of potential end

  11. Microalgae: An Alternative Source of Renewable Energy

    Directory of Open Access Journals (Sweden)

    A. Z. A. Saifullah

    2016-08-01

    Full Text Available This paper presents an overview on the potentiality of microalgae with particular emphasis as a sustainable renewable energy source for biodiesel. One of the most important dilemmas of the modern world is to supply maximal amount of energy with minimal environmental impact. The total energy demand of our planet is increasing with population growth whereas the fossil fuel reserves are dwindling swiftly. Biodiesel produced from biomass is widely considered to be one of the most sustainable alternatives to fossil fuels and a viable means for energy security and environmental and economic sustainability. But as a large area of arable land is required to cultivate biodiesel producing terrestrial plants, it may lead towards food scarcity and deforestation. Microalgae have a number of characteristics that allow the production concepts of biodiesel which are significantly more sustainable than their alternatives. Microalgae possess high biomass productivity, oils with high lipid content, fast growth rates, possibility of utilizing marginal and infertile land, capable of growing in salt water and waste streams, and capable of utilizing solar light and CO2 gas as nutrients.

  12. Wind energy. Views on the environment: clean and green

    Energy Technology Data Exchange (ETDEWEB)

    Gray, Thomas O.

    1999-12-01

    As the United States grapples with the issue of global climate change resulting from fossil fuel combustion, and as the U.S. Congress and individual state legislatures consider restructuring the electric utility industry, lawmakers should keep in mind the environmental preferability of renewable energy sources such as wind and the long, continuing record of public support for them. This is particularly important in view of restructuring, which will have the effect of shifting decisions about the type and quantity of new power plants to be built from utility executives to the general public. Preliminary information suggests that ''green,'' or environmentally-friendly, power sources could win a significant market share. In addition to creating new demand for clean energy sources, this development is likely to create a committed, educated political constituency for clean energy that has not existed in the past. In such an altered environment for the selection of new generation, public attitudes on the desirability of various power sources will become much more important than they have in the past. The purpose of this paper is to briefly summarize public opinion surveys on the environment in general, renewable energy in general, and wind energy in particular in that order, using data gathered from polling in the U.S., the United Kingdom, and Canada. At this writing, more than 16 years after the first wind plants began going up in California, there is a solid and growing body of information available on public acceptance of wind energy. This paper draws on more than 25 surveys conducted over the years on wind and renewables, as well as individual findings on attitudes on the environment from other polls. An abbreviated summary of the public attitudes reviewed in this document is as follows: Views on the Environment: Public concern about protecting the environment, and particularly those aspects of the environment that relate to human health, such as

  13. Clean air renewable energy (CARE) coalition : a case study

    International Nuclear Information System (INIS)

    This paper highlights the opportunity for new partnerships between business and non-governmental organizations in the field of sustainable development through the growing convergence of interests. The authors also briefly describe both Suncor Energy and the Pembina Institute for Appropriate Development stances on sustainable development. Since 1990, both organizations have collaborated on the future of the emerging renewable energy industry. Renewable energy represents an energy source diversification through the regional creation of jobs and improved air quality and associated benefits resulting from the reductions in greenhouse gas emissions. The Clean Air Renewable Energy Coalition (Coalition) was established in December 2000 in order to assess the barriers to capital investment in the renewable energy industry. It was revealed that the international community as a whole was further ahead than Canada in terms of renewable support, production and export of technology and services. Some of the challenges facing the industry are: low demand for renewables and low supply. The coalition allowed for the joint identification of desired policy changes, such as new tax incentives for renewable energy supply and demand. Efforts were made in inviting the support of industry, municipalities and environmental non governmental organizations. The list of members that have joined the coalition to date was shown. The coalition is asking for consumer green energy credit, designed for the creation of demand and the education of the general public, and producer incentives to increase supply. The proposals were explained, as well as the strategic principles underlying them. A new tax incentive was announced in the December 2001 Canadian federal budget. The authors concluded by mentioning some future opportunities and the lessons learned on the importance of the right partners, of broad-based advocacy, of targeted and focuses messages, and of evolutionary change

  16. Clean/alternative fueled fleet programs - 1990 Amendments to the Clean Air Act, the Colorado Air Pollution Prevention and Control Act, and Denver City and County regulations

    International Nuclear Information System (INIS)

    Despite substantial regulations for nearly two decades, attainment of this ambient standards for ozone and carbon monoxide (CO) remain difficult goals to achieve, Even with of ozone precursors and CO. The 1990 Amendments to the Clean Air Act (CAA90) prescribe further reductions of mobile source emissions. One such reduction strategy is using clean fuels, such as methanol, ethanol, or other alcohols (in blends of 85 percent or more alcohol with gasoline or other fuel), reformulated gasoline or diesel, natural gas, liquified petroleum gas, hydrogen, or electricity. There are regulatory measures involving special fuels which will be required in areas heavily polluted with ozone and CO. The state of Colorado recently passed the 1992 Air Pollution Prevention and Control Act which included provisions for the use of alternative fuels which will be implemented in 1994. In addition to adhering to the Colorado state regulations, the city and county of Denver also have regulations pertaining to the use of alternative fuels in fleets of 10 or more vehicles. Denver's program began in 1992. This paper will address the issue of fleet conversion and its impact on industry in Colorado, and Denver in particular

    Solubility testing with actual High Level Waste tank sludge has been conducted in order to evaluate several alternative chemical cleaning technologies for the dissolution of sludge residuals remaining in the tanks after the exhaustion of mechanical cleaning and sludge sluicing efforts. Tests were conducted with archived Savannah River Site (SRS) radioactive sludge solids that had been retrieved from Tank 5F in order to determine the effectiveness of an optimized, dilute oxalic/nitric acid cleaning reagent toward dissolving the bulk non-radioactive waste components. Solubility tests were performed by direct sludge contact with the oxalic/nitric acid reagent and with sludge that had been pretreated and acidified with dilute nitric acid. For comparison purposes, separate samples were also contacted with pure, concentrated oxalic acid following current baseline tank chemical cleaning methods. One goal of testing with the optimized reagent was to compare the total amounts of oxalic acid and water required for sludge dissolution using the baseline and optimized cleaning methods. A second objective was to compare the two methods with regard to the dissolution of actinide species known to be drivers for SRS tank closure Performance Assessments (PA). Additionally, solubility tests were conducted with Tank 5 sludge using acidic and caustic permanganate-based methods focused on the “targeted” dissolution of actinide species.

    2015-07-06

    The testing presented in this report is in support of the investigation of the Alternative Chemical Cleaning program to aid in developing strategies and technologies to chemically clean radioactive High Level Waste tanks prior to tank closure. The data and conclusions presented here were the examination of the corrosion rates of A285 carbon steel and 304L stainless steel when interacted with the chemical cleaning solution composed of 0.18 M nitric acid and 0.5 wt. % oxalic acid. This solution has been proposed as a dissolution solution that would be used to remove the remaining hard heel portion of the sludge in the waste tanks. This solution was combined with the HM and PUREX simulated sludge with dilution ratios that represent the bulk oxalic cleaning process (20:1 ratio, acid solution to simulant) and the cumulative volume associated with multiple acid strikes (50:1 ratio). The testing was conducted over 28 days at 50°C and deployed two methods to invest the corrosion conditions; passive weight loss coupon and an active electrochemical probe were used to collect data on the corrosion rate and material performance. In addition to investigating the chemical cleaning solutions, electrochemical corrosion testing was performed on acidic and basic solutions containing sodium permanganate at room temperature to explore the corrosion impacts if these solutions were to be implemented to retrieve remaining actinides that are currently in the sludge of the tank.

  20. Clean energy industries and rare earth materials: Economic and financial issues

    International Nuclear Information System (INIS)

    In the last few years, rare earth materials (REM) prices have experienced a strong increase due to geopolitical and sustainability issues. Financial markets could already have factored in concerns about shortages of REM supplies into clean energy companies’ valuations. We use a multifactor market model for the period January 2006 to September 2012 to analyze the impact of REM price trends – specifically dysprosium and neodymium – on six clean energy indices (NYSE–BNEF) tracking the world's most important companies in the clean energy sector. The results show that during period of price increase, there is a negative relationships between REM price changes and the stock market performance of some clean energy indices. The European clean energy index is also negatively affected, and this effect could be relevant to policy makers, considering that Europe is implementing some relevant policy actions to support the development of the clean energy industry. - Highlights: • Clean energy is an industry with a double-digit growth market rate in the last years. • Rare earth materials are a key component in the development process of this industry. • Recently REMs’ prices have skyrocketed and the clean energy industry is in turmoil. • We analyze the effect of REMs price on the stock market performances of clean industry. • We find negative relation between REMs price increase and stock market performances

    2012-01-01

    Oxygen systems are susceptible to fires caused by particle and nonvolatile residue (NVR) contaminants, therefore cleaning and verification is essential for system safety. . Cleaning solvents used on oxygen system components must be either nonflammable in pure oxygen or complete removal must be assured for system safety. . CFC -113 was the solvent of choice before 1996 because it was effective, least toxic, compatible with most materials of construction, and non ]reactive with oxygen. When CFC -113 was phased out in 1996, HCFC -225 was selected as an interim replacement for cleaning propulsion oxygen systems at NASA. HCFC-225 production phase-out date is 01/01/2015. HCFC ]225 (AK ]225G) is used extensively at Marshall Space Flight Center and Stennis Space Center for cleaning and NVR verification on large propulsion oxygen systems, and propulsion test stands and ground support equipment. . Many components are too large for ultrasonic agitation - necessary for effective aqueous cleaning and NVR sampling. . Test stand equipment must be cleaned prior to installation of test hardware. Many items must be cleaned by wipe or flush in situ where complete removal of a flammable solvent cannot be assured. The search for a replacement solvent for these applications is ongoing.

    1978-04-01

    The Workshop on Alternative Energy Strategies, conducted from 1974 through 1977, was an international study group formed to develop consistent national energy alternatives within a common analytical framework and global assumptions. A major component of this activity was the demand program, which involved preparation of highly disaggregated demand estimates based upon estimates of energy-consuming activities and energy requirements per unit of activity reported on a consistent basis for North America, Europe, and Japan. Comparison of the results of these studies reveals that North America requires more energy per unit of activity in many consumption categories, that major improvements in efficiency will move North America close to current European and Japanese efficiencies, and that further improvements in European and Japanese efficiencies may be anticipated as well. When contrasted with expected availabilities of fuels, major shortfalls of oil relative to projected demands emerge in the eighties and nineties. Some approaches to investment in efficiency improvements which will offset these difficulties are discussed.

    2010-05-01

    High initial costs can impede the deployment of clean energy technologies. Financing can reduce these costs. And, state, municipal, and utility-sponsored loan programs have emerged to fill the gap between clean energy technology financing needs and private sector lending. In general, public loan programs are more favorable to clean energy technologies than are those offered by traditional lending institutions; however, public loan programs address only the high up-front costs of clean energy systems, and the technology installed under these loan programs rarely supports clean energy production at levels that have a notable impact on the broader energy sector. This report discusses ways to increase the impact of these loan programs and suggests related policy design considerations.

    An electrical vehicle environment was established to promote research and technology development in the area of high power energy management. The project incorporates a topology that permits parallel development of an alternative energy delivery system and an energy storage system. The objective of the project is to develop technologies, specifically power electronics, energy storage electronics and controls that provide efficient and effective energy management between electrically powered devices in alternative energy vehicles plugin electric vehicles, hybrid vehicles, range extended vehicles, and hydrogen-based fuel cell vehicles. In order to meet the project objectives, the Vehicle Energy Management System (VEMS) was defined and subsystem requirements were obtained. Afterwards, power electronics, energy storage electronics and controls were designed. Finally, these subsystems were built, tested individually, and integrated into an electric vehicle system to evaluate and optimize the subsystems performance. Phase 1 of the program established the fundamental test bed to support development of an electrical environment ideal for fuel cell application and the mitigation of many shortcomings of current fuel cell technology. Phase 2, continued development from Phase 1, focusing on implementing subsystem requirements, design and construction of the energy management subsystem, and the integration of this subsystem into the surrogate electric vehicle. Phase 2 also required the development of an Alternative Energy System (AES) capable of emulating electrical characteristics of fuel cells, battery, gen set, etc. Under the scope of the project, a boost converter that couples the alternate energy delivery system to the energy storage system was developed, constructed and tested. Modeling tools were utilized during the design process to optimize both component and system design. This model driven design process enabled an iterative process to track and evaluate the impact

    International Nuclear Information System (INIS)

    This study aims to investigate the barriers which impede the promotion of Energy Efficient Building (EEB), and to propose solutions to alleviate these barriers by capturing the benefits from Clean Development Mechanism (CDM), in the context of China. Through comprehensive literature review, eight types of significant barriers are identified, including weak enforcement of government policies, market inefficiency, information barrier, small and scattering buildings, fragmentation of the construction industry, perceived high risk, higher initial cost, and difficulty in energy management. To overcome the barriers, the potential of CDM to facilitate EEB promotion is then discussed. These barriers are verified and potential solutions are tested with a questionnaire survey conducted among five professional groups in China, i.e. designers, project managers, quantity surveyors, marketing managers and property managers. The results suggest that they generally identified with the barriers. However, their limited awareness of CDM implies that corresponding policies should be formulated and implemented to improve their capability of providing more EEBs with CDM. - Highlights: ► Eight types of significant barriers to the implement of EEB are identified. ► The sources and roots of barriers are verified with the industry professionals. ► Benefits of CDM to EEB are discussed. ► There is limited awareness of CDM in building sector. ► Overcoming or alleviating these barriers through CDM and other sources are proposed

    Reinhardt, Michael Henry

    An electric vehicle heating system and a solar thermal coffee dryer are presented as case studies in alternative energy system design optimization. Design optimization tools are compared using these case studies, including linear programming, integer programming, and fuzzy integer programming. Although most decision variables in the designs of alternative energy systems are generally discrete (e.g., numbers of photovoltaic modules, thermal panels, layers of glazing in windows), the literature shows that the optimization methods used historically for design utilize continuous decision variables. Integer programming, used to find the optimal investment in conservation measures as a function of life cycle cost of an electric vehicle heating system, is compared to linear programming, demonstrating the importance of accounting for the discrete nature of design variables. The electric vehicle study shows that conservation methods similar to those used in building design, that reduce the overall UA of a 22 ft. electric shuttle bus from 488 to 202 (Btu/hr-F), can eliminate the need for fossil fuel heating systems when operating in the northeast United States. Fuzzy integer programming is presented as a means of accounting for imprecise design constraints such as being environmentally friendly in the optimization process. The solar thermal coffee dryer study focuses on a deep-bed design using unglazed thermal collectors (UTC). Experimental data from parchment coffee drying are gathered, including drying constants and equilibrium moisture. In this case, fuzzy linear programming is presented as a means of optimizing experimental procedures to produce the most information under imprecise constraints. Graphical optimization is used to show that for every 1 m2 deep-bed dryer, of 0.4 m depth, a UTC array consisting of 5, 1.1 m 2 panels, and a photovoltaic array consisting of 1, 0.25 m 2 panels produces the most dry coffee per dollar invested in the system.

    The Clean Air Act Amendments (CAAA) of 1990 rely primarily on the use of market incentives to stimulate least-cost compliance choices by electric utilities. Because of the potential risks associated with selecting Clean Coal Technologies (CCTs) and the public-good nature of technology commercialization, electric utilities may be reluctant to adopt CCTs as part of their compliance strategies. This paper examines the nature of the risks and perceived impediments to adopting CCTs as a compliance option. It also discusses the incentives that regulatory policy makers could adopt to mitigate these barriers to CCT adoption. (VC)

    The Clean Energy Ministerial (CEM) is a high-level global forum to share best practices and promote policies and programs that advance clean energy technologies and accelerate the transition to a global clean energy economy. The CEM works to increase energy efficiency, expand clean energy supply, and enhance clean energy access worldwide. To achieve these goals, the CEM pursues a three-part strategy that includes high-level policy dialogue, technical cooperation, and engagement with the private sector and other stakeholders. Each year, energy ministers and other high-level delegates from the 23 participating CEM governments come together to discuss clean energy, review clean energy progress, and identify tangible next steps to accelerate the clean energy transition. The U.S. Department of Energy, which played a crucial role in launching the CEM, hosted the first annual meeting of energy ministers in Washington, DC, in June 2010.

    2003-07-01

    The Environmental Law and Policy Center of Illinois has recently released several publications promoting clean energy development to improve environmental quality and public health for the Midwest. This presentation emphasized how the clean energy development plan can create new jobs and stimulate economic growth. For example, the electric power industry is currently relying on 1950's energy technology. Modernizing the electricity industry would be good for both the economy and the environment. Repowering the industry would promote energy efficiency and renewable energy sources. The presentation also compared a business-as-usual (BAU) scenario and a clean energy development plan scenario for 2010 and 2020. It was suggested that policy changes may be required to ensure change. In the BAU scenario, electricity demand would increase annually, large additions of natural gas capacity would be used to meet the demand, and coal plants would increase their output. Under the clean energy development plan, electricity demand would flatten out, coal and nuclear plants would be replaced with renewables (mostly wind) or clean, natural gas generation. Under the clean energy development plan NOx would be reduced by 71 per cent, SOx by 56 per cent, mercury by 50 per cent, and carbon dioxide by 51 per cent. The clean energy development plan improves the environment by reducing air and water pollution and improves electricity reliability. 8 tabs., 20 figs.

  17. Methodology and data used for estimating the complex-wide impacts of alternative environmental restoration clean-up goals

    International Nuclear Information System (INIS)

    This paper describes the methodologies and data used for estimating the complex-wide impacts of alternative strategies for conducting remediation of all DOE sites and facilities, but does not address issues relating to Waste Management capabilities. Clean-up strategies and their corresponding goals for contaminated media may be driven by concentration-based regulatory standards, land-use standards (e.g., residential, industrial, wild life reserve, or totally restricted), risk-based standards, or other standards determined through stakeholder input. Strategies implemented to achieve these goals usually require the deployment of (a) clean-up technologies to destroy, remove, or contain the contaminants of concern; (b) institutional controls to prevent potential receptors from coming into contact with the contaminants; or (c) a combination of the above

    The U.S. Department of Energy Pacific Region Clean Energy Application Center (PCEAC) was formed in 2009 by the U.S. Department of Energy (DOE) and the California Energy Commission to provide education, outreach, and technical support to promote clean energy -- combined heat and power (CHP), district energy, and waste energy recovery (WHP) -- development in the Pacific Region. The region includes California, Nevada, Hawaii, and the Pacific territories. The PCEAC was operated as one of nine regional clean energy application centers, originally established in 2003/2004 as Regional Application Centers for combined heat and power (CHP). Under the Energy Independence and Security Act of 2007, these centers received an expanded charter to also promote district energy and waste energy recovery, where economically and environmentally advantageous. The centers are working in a coordinated fashion to provide objective information on clean energy system technical and economic performance, direct technical assistance for clean energy projects and additional outreach activities to end users, policy, utility, and industry stakeholders. A key goal of the CEACs is to assist the U.S. in achieving the DOE goal to ramp up the implementation of CHP to account for 20% of U.S. generating capacity by 2030, which is estimated at a requirement for an additional 241 GW of installed clean technologies. Additional goals include meeting the Obama Administration goal of 40 GW of new CHP by 2020, key statewide goals such as renewable portfolio standards (RPS) in each state, California’s greenhouse gas emission reduction goals under AB32, and Governor Brown’s “Clean Energy Jobs Plan” goal of 6.5 GW of additional CHP over the next twenty years. The primary partners in the PCEAC are the Department of Civil and Environmental Engineering and the Energy and Resources Group (ERG) at UC Berkeley, the Advanced Power and Energy Program (APEP) at UC Irvine, and the Industrial Assessment Centers (IAC

    The Clean Energy Partnership (CEP)- an alliance of currently sixteen leading companies in Germany- shows that it may be doable to establish hydrogen as 'fuel of the future'. With Air Liquide, Berliner Verkehrsbetriebe (BVG), BMW, Daimler, EnBW, Ford, GM/Opel, Hamburger Hochbahn, Honda, Linde, Shell, Siemens, Total, Toyota, Vattenfall Europe and Volkswagen, the project partners include technology, oil and utility companies as well as major car manufacturers and two leading public transport companies of the two biggest German cities. The goal of CEP is to test using hydrogen- and fuel-cell technology on an everyday basis in the mobility sector with regard to individual traffic and public transport. Challenges are the use and supply of ''green'' hydrogen as well the serial production of hydrogen vehicles as well as the extension of the hydrogen filling station network. Nevertheless, Germany is a frontrunner when it comes to hydrogen mobility with currently 15 stations and 50% green hydrogen offered already today. (orig.)

    2015-12-01

    Numerous climate change education efforts exist that aim to enable citizens and society to make informed decisions addressing environmental and societal issues arising from climate change. To extend the reach and impact of these efforts, it is necessary to coordinate them in order to reach a greater collective impact. The Collective Impact model, as described by Kania & Kramer (2011), requires five elements: 1) a common agenda; 2) shared measurement systems; 3) mutually reinforcing activities; 4) continuous communication; and 5) a well-funded backbone support organization. The CLEAN Network, as an example of a rudimentary form of such an organization, engages in continuous communication through weekly teleconferences, an active listserv and other activities to share resources, activities, and ideas that is moving the network to develop common understandings that will likely lead to the development of effective collective impact on increasing climate and energy literacy. A Spring 2013 survey of the CLEAN Network provided insight as to how the CLEAN Network was addressing member needs and identified what other support was needed to increase its collective impact. In addition, community discussions identified the components needed for an effective overarching backbone support organization. A Fall 2015 survey of the CLEAN Network and the broader climate change education community is being conducted to examine 1) how the CLEAN Network make up and needs have evolved and how they compare to the broader community, and 2) to gather further input into the shaping of the elements of collective impact on climate and energy literacy. This presentation will describe the results from the 2015 survey and compare them to the 2013 survey and the community discussions. This will include describing the CLEAN Network's evolving professional make up, engagement of its members network activities, the importance of the network to members; how the findings compare with the broader climate

    2015-12-01

    The need for continuous monitoring of polychlorinated biphenyls (PCBs) has necessitated the development of analytical techniques that are sensitive and selective with minimal reagent requirement. In light of this, we developed a column for clean-up of soil and sediment extracts, which is less demanding in terms of the amount of solvent and sorbent. The dual-layer column consists of acidified silica gel and molecularly imprinted polymers (MIPs). MIPs were synthesized via aqueous suspension polymerization using PCB 15 as the dummy template, 4-vinylpyridine as the functional monomer and ethylene glycol dimethacrylate as the cross-linker and the obtained particles characterized via SEM, BET, and batch rebinding assays. Pre-concentration of the spiked real-world water sample using MISPE gave recoveries between 85.2 and 104.4% (RSD clean-up of extracts from complex matrices provided recoveries of 91.6-102.5% (RSD clean-up using acidified silica (70.4-90.5%; RSD clean-up procedure for continuous monitoring of PCBs. Method detection limits were 0.01-0.08 ng g(-1) and 0.002-0.01 ng mL(-1) for solid matrices and water, respectively.

  3. Essays on Infrastructure Design and Planning for Clean Energy Systems

    Science.gov (United States)

    Kocaman, Ayse Selin

    The International Energy Agency estimates that the number of people who do not have access to electricity is nearly 1.3 billion and a billion more have only unreliable and intermittent supply. Moreover, current supply for electricity generation mostly relies on fossil fuels, which are finite and one of the greatest threats to the environment. Rising population growth rates, depleting fuel sources, environmental issues and economic developments have increased the need for mathematical optimization to provide a formal framework that enables systematic and clear decision-making in energy operations. This thesis through its methodologies and algorithms enable tools for energy generation, transmission and distribution system design and help policy makers make cost assessments in energy infrastructure planning rapidly and accurately. In Chapter 2, we focus on local-level power distribution systems planning for rural electrification using techniques from combinatorial optimization. We describe a heuristic algorithm that provides a quick solution for the partial electrification problem where the distribution network can only connect a pre-specified number of households with low voltage lines. The algorithm demonstrates the effect of household settlement patterns on the electrification cost. We also describe the first heuristic algorithm that selects the locations and service areas of transformers without requiring candidate solutions and simultaneously builds a two-level grid network in a green-field setting. The algorithms are applied to real world rural settings in Africa, where household locations digitized from satellite imagery are prescribed. In Chapter 3 and 4, we focus on power generation and transmission using clean energy sources. Here, we imagine a country in the future where hydro and solar are the dominant sources and fossil fuels are only available in minimal form. We discuss the problem of modeling hydro and solar energy production and allocation, including

    Gazing the introduction target for fiscal 2000 and 2010, the paper arranged comprehensively and systematically the trend in Japan and overseas of clean energy cars and described subjects. Themes of the study to be promoted in terms of electric cars are: Li secondary batteries, heightening of performance of batteries such as Ni-hydrogen, power generation/power storage hybridization to make the long-distance travel possible. For the price reduction, the body is so made as to make it possible to select three kinds of power unit, that is, gasoline, hybrid, and electricity. Low noise and easy operation are also important. As to natural gas vehicles, the price is more than three times as high as that of gasoline vehicles, and relaxation of the related regulations on metal tanks, the Road Traffic Act, etc. is necessary. It is indispensable to establish quantity production and technical standards and reduce cost by the remodeling for bi-fueling with gasoline engines, development of FRP tanks, etc. Methanol vehicles are the closest to gasoline vehicles, but the introduction is delayed having no groups for generalization. Solar and hydrogen cars are promising, but are on a stage of developing the basic technology. 43 figs., 104 tabs.

    In order for renewable energy to play a dominant role in the global electricity supply mix, emerging renewable energy technologies - such as wave, tidal, enhanced geothermal, and 3rd generation photovoltaic technologies - must prove their technical merits and achieve cost parity with conventional sources of supply. BC Hydro, a government-owned electric utility, launched an Alternative and Emerging Energy Strategy that describes its role as an enabler of technology innovation. This paper describes BC Hydro's goal, objectives and actions to accelerate the commercialization that will yield a diversity of supply options and a growing, local clean-tech cluster.

    2003-01-01

    Societies in the 21st century require enormous amounts of energy to drive the machines of commerce and to sustain the lifestyles that many people have come to expect. Today, most of this energy is derived from oil, natural gas, and coal, supplemented by nuclear power. Local exceptions exist, but oil is by far the most common source of energy worldwide. Oil resources, however, are nonrenewable and concentrated in only a few places around the globe, creating uncertainty in long-term supply for many nations. At the time of the Middle East oil embargo of the 1970s, about a third of the United States oil supply was imported, mostly from that region. An interruption in the flow of this import disrupted nearly every citizen’s daily life, as well as the Nation’s economy. In response, the Federal Government launched substantial programs to accelerate development of means to increasingly harness “alternative energies”—primarily biomass, geothermal, solar, and wind. The new emphasis on simultaneously pursuing development of several sources of energy recognized the timeless wisdom found in the proverb of “not putting all eggs in one basket.” This book helps explain the role that geothermal resources can play in helping promote such diversity and in satisfying our Nation’s vast energy needs as we enter a new millennium. For centuries, people have enjoyed the benefits of geothermal energy available at hot springs, but it is only through technological advances made during the 20th century that we can tap this energy source in the subsurface and use it in a variety of ways, including the generation of electricity. Geothermal resources are simply exploitable concentrations of the Earth’s natural heat (thermal energy). The Earth is a bountiful source of thermal energy, continuously producing heat at depth, primarily by the decay of naturally occurring radioactive isotopes—principally of uranium, thorium, and potassium—that occur in small amounts in all rocks

    This report builds on the emerging body of literature seeking to identify quantitative connections between clean energy policy and renewable energy. The methods presented test the relationships between a broad set of policies and clean energy resources (energy efficiency, biomass, geothermal, solar, and wind). Energy efficiency findings are an initial foray into this type of analysis and indicate significant connections between reduced energy use and buildings codes, energy efficiency resource standards (in some cases), and electricity price. Renewable energy findings specify that there is most often a relationship between state policies and solar and wind development, indicating that while policies might apply to a wide variety of renewable resources, further tailoring of policy specifics to resource needs may lead to increased development of a wider variety of renewable energy resources. Further research is needed to refine the connections between clean energy development and policy, especially in the area of the impact of the length of time that a policy has been in place.

    The Mesaba Energy Project is a nominal 600 MW integrated gasification combine cycle power project located in Northeastern Minnesota. It was selected to receive financial assistance pursuant to code of federal regulations (?CFR?) 10 CFR 600 through a competitive solicitation under Round 2 of the Department of Energy?s Clean Coal Power Initiative, which had two stated goals: (1) to demonstrate advanced coal-based technologies that can be commercialized at electric utility scale, and (2) to accelerate the likelihood of deploying demonstrated technologies for widespread commercial use in the electric power sector. The Project was selected in 2004 to receive a total of $36 million. The DOE portion that was equally cost shared in Budget Period 1 amounted to about $22.5 million. Budget Period 1 activities focused on the Project Definition Phase and included: project development, preliminary engineering, environmental permitting, regulatory approvals and financing to reach financial close and start of construction. The Project is based on ConocoPhillips? E-Gas? Technology and is designed to be fuel flexible with the ability to process sub-bituminous coal, a blend of sub-bituminous coal and petroleum coke and Illinois # 6 bituminous coal. Major objectives include the establishment of a reference plant design for Integrated Gasification Combined Cycle (?IGCC?) technology featuring advanced full slurry quench, multiple train gasification, integration of the air separation unit, and the demonstration of 90% operational availability and improved thermal efficiency relative to previous demonstration projects. In addition, the Project would demonstrate substantial environmental benefits, as compared with conventional technology, through dramatically lower emissions of sulfur dioxide, nitrogen oxides, volatile organic compounds, carbon monoxide, particulate matter and mercury. Major milestones achieved in support of fulfilling the above goals include obtaining Site, High Voltage

  15. Interfacial Effects in Polymer Membranes for Clean Energy

    Science.gov (United States)

    Soles, Christopher

    2013-03-01

    Polymeric membranes are critical components in several emerging clean energy technologies. Examples include proton exchange membranes for hydrogen fuel cells, anion exchange membranes for alkaline fuel cells, flow batteries, and even block copolymer membranes for solid electrolytes/separators in lithium ion and other battery technologies. In all of these examples the function of the membrane is to physically separate two reactive electrodes or reactants, but allow the transport or exchange of specific ions through the membrane between the active electrodes. The flow of the charged ionic species between the electrodes can be used to balance the flow of electrons through an external electrical circuit that connects the electrodes, thereby storing or delivering charge electrochemically. In this presentation I will review the use of polymeric membranes in electrochemical energy storage technologies and discuss the critical issues related to the membranes that hinder these technologies. In particular I will also focus on the role the polymer membrane interface on device performance. At some point the polymer membrane must be interfaced with an active electrode or catalyst and the nature of this interface can significantly impact performance. Simulations of device performance based on bulk membrane transport properties often fail to predict the actual performance and empirical interfacial impedance terms usually added to capture the device performance. In this presentation I will explore the origins of this interfacial impedance in the different types of fuel cell membranes (proton and alkaline) by creating model thin film membranes where all of the membrane can be considered interfacial. We then use these thin films as a surrogate for the interfacial regions of a bulk membrane and then quantify the structure, dynamics, and transport properties of water and ions in the confined interfacial films. Using neutron reflectivity, grazing incidence X-ray diffraction, and

  17. Promotional issues on alternative energy technologies in Nepal

    International Nuclear Information System (INIS)

    Alternative energy technologies are being disseminated in many countries with an objective to reduce the uses of traditional and commercial energy sources. These technologies convert local resources to usable energy forms. Since the scale of these technologies is small, their implementation is targeted mainly to individual households or small communities. However, due to various constraints, these implementation programmes have not been very successful. In this paper, the author introduces the main characteristics of alternative energy technologies used in Nepal and discusses promotional barriers for their implementation. It is hoped that this paper would help energy policy makers to devise better alternative energy programmes

While it is widely accepted that rising oil prices are good for the financial performance of alternative energy companies, there has been relatively little statistical work done to measure just how sensitive the financial performance of alternative energy companies are to changes in oil prices. In this paper, a four variable vector autoregression model is developed and estimated in order to investigate the empirical relationship between alternative energy stock prices, technology stock prices, oil prices, and interest rates. Our results show technology stock prices and oil prices each individually Granger cause the stock prices of alternative energy companies. Simulation results show that a shock to technology stock prices has a larger impact on alternative energy stock prices than does a shock to oil prices. These results should be of use to investors, managers and policy makers. (author)

    2014-10-01

    The Washoe Tribe of Nevada and California was awarded funding to complete the Washoe Tribe Alternative Energy Feasibility Study project. The main goal of the project was to complete an alternative energy feasibility study. This study was completed to evaluate “the potential for development of a variety of renewable energy projects and to conduct an alternative energy feasibility study that determines which alternative energy resources have the greatest economic opportunity for the Tribe, while respecting cultural and environmental values” (Baker-Tilly, 2014). The study concluded that distributed generation solar projects are the best option for renewable energy development and asset ownership for the Washoe Tribe. Concentrating solar projects, utility scale wind projects, geothermal, and biomass resource projects were also evaluated during the study and it was determined that these alternatives would not be feasible at this time.

    The capital intensive nature of clean energy technologies suggests that manufacturing clean energy equipment has the potential to support state and local economic development efforts. However, manufacturing siting decisions tend to be complex and multi-variable decision processes that require in-depth knowledge of specific markets, the logistical requirements of a given technology, and insight into global clean tech trends. This presentation highlights the potential of manufacturing in supporting economic development opportunities while also providing examples of the financial considerations affecting manufacturing facility siting decisions for wind turbine blades and solar PV. The presentation also includes discussion of other more qualitative drivers of facility siting decisions as gleaned from NREL industry interviews and discusses strategies state and local policymakers may employee to bolster their chances of successfully attracting clean energy manufacturers to their localities.

    Development of a comprehensive and effective global clean technology cooperation framework will require years of experimenting and evaluation with new instruments and institutional arrangements before it is clear what works on which scale and in which region or country. In presenting concrete examples, this paper aims to set the first step in that process by highlighting successful models and innovative approaches that can inform efforts to ramp up clean energy technology cooperation. This paper reviews current mechanisms and international frameworks for global cooperation on clean energy technologies, both within and outside of the UNFCCC, and provides selected concrete options for scaling up global cooperation on clean energy technology RD&D, enabling environment, and financing.

  14. Managing intellectual property rights in cross-border clean energy collaboration: The case of the U.S.–China Clean Energy Research Center

    International Nuclear Information System (INIS)

    This paper examines how the United States and China are implementing the most ambitious model of bilateral clean energy technology cooperation to date: The U.S.–China Clean Energy Research Center (CERC). It finds that the CERC has been able to generate new IP through RD and D activities, though minimal IP has come from collaborative activities involving both U.S. and Chinese participants. Many participants reported that the CERC's Technology Management Plan (TMP) mitigated their IP concerns, though few have tested its efficacy or enforceability. While it is too early to comprehensively assess the efforts of the CERC, it is increasingly evident that the CERC provides a model for collaborative clean energy RD and D that is unique in the history of U.S.–China collaborations in this area. The TMP may ultimately play an important role in building trust among the consortia participants, which could lead to even more constructive collaborations in the future, and serve as a model for future bilateral cooperation agreements. Without sustained support, and continued attention to IP concerns, it will be even harder for China and the United States to make progress towards true cross-national research collaborations which ultimately could produce considerable global benefits, particularly in the clean energy field. - Highlights: • The CERC has been able to generate new IP through collaborative RD and D activities. • Minimal IP has come from cross-national collaborative activities. • The TMP has mitigated IP concerns, though few have tested its enforceability. • The CERC provides a unique model for collaborative clean energy RD and D. • The TMP may ultimately help to build trust among the consortia participants

    In June 2009, the State of Hawaii enacted an Energy Efficiency Portfolio Standard (EEPS) with a target of 4,300 gigawatt hours (GWh) by 2030 (Hawaii 2009). Upon setting this goal, the Hawaii Clean Energy Initiative, Booz Allen Hamilton (BAH), and the National Renewable Energy Laboratory (NREL), working with select local stakeholders, partnered to execute the first key step toward attaining the EEPS goal: the creation of a high-resolution roadmap outlining key areas of potential electricity savings. This roadmap was divided into two core elements: savings from new construction and savings from existing buildings. BAH focused primarily on the existing building analysis, while NREL focused on new construction forecasting. This report presents the results of the Booz Allen Hamilton study on the existing building stock of Hawaii, along with conclusions on the key drivers of potential energy efficiency savings and on the steps necessary to attain them.

    2009-07-01

    The author outlines the strong current development of wind and solar energy in China, with an increasing and already rather high wind energy production, and a solar panel production which is, until now, mostly exported. He observes that the development of these industries is based on economic, political and security issues: China is now strongly dependent on energy imports (even coal imports), looks to reduce the social cost of pollution and environment degradation, and wants to be a major actor of the renewable energy sector. The development of this sector is mainly financed by public investments, but the clean sector is weakened by the slow development of distribution networks, and by a too fragmented production market. The author discusses the new approach adopted by the Chinese government to overcome these drawbacks, and the consequences of this approach for the international context

  19. Renewable energy projects under the clean development mechanism : myth or reality?

    International Nuclear Information System (INIS)

    This paper discussed the fate of Renewable Energy (RE) in Canada. The importance of RE is now increasing from both an environmental and energy security perspective, and has been projected as a key solution to climate change problems. RE is also one of the key greenhouse gas (GHG) mitigation options to be considered under the Clean Development Mechanism (CDM). Canada possesses more than 100 GW of technical potential for RE resources, including wind, solar and small hydro. Less than 10 per cent of this potential has been exploited to date. A number of programs have been developed to facilitate the deployment of Renewable Energy Technologies (RETs), including financial incentives, renewable portfolio standards and green power procurement policies. However, Canadian policies are less aggressive than those of other countries. This study showed that the supply of certified emission reductions (CERs) resulting from negative and low cost CDM options, such as energy efficiency improvements, afforestation and reforestation, could surpass the total demand for CERs during the first commitment period of the Kyoto Protocol. Implementation of RE projects under the CDM could be undermined. It was recommended that increased support of the Global Environment Facility (GEF), use of the Special Climate Change Fund, and special attention to RE from both host and investing countries should become mandatory as alternative strategies to promote RE. In addition, it should be acknowledged that the development of RETs faces a number of barriers and challenges, including competition from conventional energy technologies; lack of customer and investor confidence; regulatory and institutional barriers; and technical barriers such as transmission access. 19 refs., 1 tab

  20. Agent-Based Modleing of Power Plants Placement to Evaluate the Clean Energy Standard Goal

    Energy Technology Data Exchange (ETDEWEB)

    Omitaomu, Olufemi A [ORNL

    2014-01-01

    There is a political push for utilities to supply a specified share of their electricity sales from clean energy resources under the clean energy standard (CES). The goal is to achieve 80% clean energy by 2035. However, there are uncertainties about the ability of the utility industry to ramp up quickly even with the incentives that will be provided. Water availability from the streams is one of the major factors. The contiguous United States is divided into eighteen water regions, and multiple states share water from a single water region. Consequently, water usage decisions made in one state (located upstream of a water region that crosses multiple states) will greatly impact what is available downstream in another state. In this paper, an agent-based modeling approach is proposed to evaluate the clean energy standard goal for water-dependent energy resources. Specifically, using a water region rather than a state boundary as a bounding envelope for the modeling and starting at the headwaters, virtual power plants are placed based on the conditions that there is: (i) suitable land to site a particular power plant, (ii) enough water that meet regulatory guidelines within 20 miles of the suitable land, and (iii) a 20-mile buffer zone from an existing or a virtual power plant. The results obtained are discussed in the context of the proposed clean energy standard goal for states that overlap with one water region.

    Herrera, Hugo Francisco Lopez

    As world population grows, and its technology evolves, the demand for electricity inexorably increases. Until now most of this electricity has been produced via fossil fuels, non-renewable energy resources that are irreversibly deteriorating our environment. On the economical aspect it does not get any better. Let's not forget market rules, the higher the demand and lower the offer, the higher the price we will have to pay. Oil is an excellent example. Some countries try to solve this situation with Pharaohnic projects, i.e. investing absurd amounts of money in 'green electricity' building monstrous dams to power equally monstrous hydroelectric power plants. The only problem with this is that it is not green at all---it does have an enormous environmental impact---it is extremely complicated and expensive to implement. It is important to point out, that this research project does not try to solve world's thirst for electricity. It is rather aimed to help solve this problematic at a much lower scale---it should be considered as an extremely small step in the right direction. It focuses on satisfying the local electricity needs with renewable, non-contaminating and locally available resources. More concisely, this project focuses on the attainment and use of hydrogen as an alternate energy source in El Paso/Juarez region. Clean technology is nowadays available to produce hydrogen and oxygen, i.e. the photoelectrolysis process. Photovoltaic cells coupled with electrolytic devices can be used to produce hydrogen and oxygen in a sustainable manner. In this research, simulation models of hybrid systems were designed and developed. They were capable to compare, predict and evaluate different options for hydrogen generation. On the other hand, with the produced hydrogen from the electrolysis process it was possible to generate electricity through fuel cells. The main objectives of the proposed research were to define how to use the resources for the attainment of hydrogen

    An assessment of the state of the art in refrigeration and insulation technologies is carried out to evaluate the potential for efficient substitutes for CFCs and HCFCs to facilitate the transition to a CFC-free environment. Opportunities for improved efficiency in domestic refrigeration, building chillers, commercial refrigeration and industrial refrigeration are evaluated. Needs for alternate refrigerants, improved components, and/or alternate cycles are identified. A summary of on-going research is presented in each area, and the potential roles of industry and government are considered. The most promising approaches for refrigeration technology fall into these categories: (1) improved vapor compressor cycles with alternate fluids, (2) Stirling cycle development and (3) advances in absorption technology. A summary of on-going research into advanced insulation, focused on vacuum-based insulation technology refrigeration is developed. Insulation applications considered include appliances, transport refrigeration, and buildings. Specific recommendations for a long-term R&D agenda are presented. The potential benefits, research, general approach, and probability of success are addressed.

  7. Alternative Approaches to High Energy Density Fusion

    Science.gov (United States)

    Hammer, J.

    2016-10-01

    This paper explores selected approaches to High Energy Density (HED) fusion, beginning with discussion of ignition requirements at the National Ignition Facility (NIF). The needed improvements to achieve ignition are closely tied to the ability to concentrate energy in the implosion, manifested in the stagnation pressure, Pstag. The energy that must be assembled in the imploded state to ignite varies roughly as Pstag-2, so among other requirements, there is a premium on reaching higher Pstag to achieve ignition with the available laser energy. The U.S. inertial confinement fusion program (ICF) is pursuing higher Pstag on NIF through improvements to capsule stability and symmetry. One can argue that recent experiments place an approximate upper bound on the ultimate ignition energy requirement. Scaling the implosions consistently in spatial, temporal and energy scales shows that implosions of the demonstrated quality ignite robustly at 9-15 times the current energy of NIF. While lasers are unlikely to reach that bounding energy, it appears that pulsed-power sources could plausibly do so, giving a range of paths forward for ICF depending on success in improving energy concentration. In this paper, I show the scaling arguments then discuss topics from my own involvement in HED fusion. The recent Viewfactor experiments at NIF have shed light on both the observed capsule drive deficit and errors in the detailed modelling of hohlraums. The latter could be important factors in the inability to achieve the needed symmetry and energy concentration. The paper then recounts earlier work in Fast Ignition and the uses of pulsed-power for HED and fusion applications. It concludes with a description of a method for improving pulsed-power driven hohlraums that could potentially provide a factor of 10 in energy at NTF-like drive conditions and reach the energy bound for indirect drive ICF.

    Scaling up for alternative energy such as solar, wind, and biofuel raises a number of environmental issues, notably changes in land use and adverse effects on wildlife. Airports offer one of the few land uses where reductions in wildlife abundance and habitat quality are necessary and socially acceptable, due to risk of wildlife collisions with aircraft. There are several uncertainties and limitations to establishing alternative energy production at airports, such as ensuring these facilities do not create wildlife attractants or other hazards. However, with careful planning, locating alternative energy projects at airports could help mitigate many of the challenges currently facing policy makers, developers, and conservationists.

    One of the pillars that holds up the stability and economic development of our society is the need to ensure a reliable and affordable supply of energy that meets our current energy needs. The high dependence on fossil fuels, our main source of primary energy, has many drawbacks mainly caused by greenhouse gases. It is urgent to address this unsustainable energy future through innovation, adoption of new energy alternatives and better use of existing technologies. In this context, hydrogen associated to renewable energy is probably an important part of that future. This paper presents a real demonstrator of energy generation and storage through the clean production of hydrogen from small wind energy. Thus, this demonstrator will allow the study of the technical and econonmic feasibility of hydrogen production. Wind energy will be stored as hydrogen for a later use. In this way hydrogen represents a form of no-loss energy battery. The use of small wind energy allows a more modular and scattered production even in developing countries. In this way, we avoid the transport of hydrogen and the electricity to produce it, improving system efficiency. Moreover, small wind systems require a lower initial investment in infrastructure which will facilitate the development of a separate market for hydrogen production. (orig.)

    A laboratory pilot study has been undertaken with the material that showed the most promise (high capacity and low pressure drop) based on the literature review and associated calculations. The best-performing air cleaner was a commercially available pleated filter that contained a thin layer of small activated carbon particles between two sheets of non-woven fibrous webbing. We will refer to this unit as the ''ozone filter'' although it is marketed for removal of volatile organic compounds (VOCs) from automobile passenger compartments. This pilot study strongly suggests that ozone air cleaning can be practical in commercial air handling systems; however, further tests are needed to assess air cleaner performance under a wider range of conditions.

  6. Transition through co-optation: Harnessing carbon democracy for clean energy

    Science.gov (United States)

    Meng, Kathryn-Louise

    This dissertation explores barriers to a clean energy transition in the United States. Clean energy is demonstrably viable, yet the pace of clean energy adoption in the U.S. is slow, particularly given the immediate threat of global climate change. The purpose of this dissertation is to examine the factors inhibiting a domestic energy transition and to propose pragmatic approaches to catalyzing a transition. The first article examines the current political-economic and socio-technical energy landscape in the U.S. Fossil fuels are central to the functioning of the American economy. Given this centrality, constellations of power have been constructed around the reliable and affordable access of fossil fuels. The fossil fuel energy regime is comprised of: political-economic networks with vested interests in continued fossil fuel reliance, and fixed infrastructure that is minimally compatible with distributed generation. A transition to clean energy threatens the profitability of fossil fuel regime actors. Harnessing structural critiques from political ecology and process and function-oriented socio-technical systems frameworks, I present a multi-level approach to identifying pragmatic means to catalyzing an energy transition. High-level solutions confront the existing structure, mid-level solutions harness synergy with the existing structure, and low-level solutions lie outside of the energy system or foster the TIS. This is exemplified using a case study of solar development in Massachusetts. Article two presents a case study of the clean energy technological innovation system (TIS) in Massachusetts. I examine the actors and institutions that support cleantech development. Further, I scrutinize the actors and institutions that help sustain the TIS support system. The concept of a catalyst is presented; a catalyst is an actor that serves to propel TIS functions. Catalysts are critical to facilitating anchoring. Strategic corporate partners are identified as powerful

  10. Clean energy funds: An overview of state support for renewable energy

    Energy Technology Data Exchange (ETDEWEB)

    Bolinger, Mark; Wiser, Ryan

    2001-04-01

    Across the United States, as competition in the supply and delivery of electricity has been introduced, states have sought to ensure the continuation of ''public benefits'' programs traditionally administered or funded by electric utilities. Many states have built into their restructuring plans methods of supporting renewable energy sources. One of the most popular policy mechanisms for ensuring such continued support has been the system-benefits charge (SBC), a non-bypassable charge to electricity customers (usually applied on a cents/kWh basis) used to collect funds for public purpose programs. Thus far, at least fourteen states have established SBC funds targeted in part towards renewable energy. This paper discusses the status and performance of these state renewable or ''clean'' energy funds supported by system-benefits charges. As illustrated later, existing state renewable energy funds are expected to collect roughly $3.5 billion through 2012 for renewable energy. Clearly, these funds have the potential to provide significant support for clean energy technologies over at least the next decade. Because the level of funding for renewable energy available under these programs is unprecedented and because fund administrators are developing innovative and new programs to fund renewable projects, a certain number of program failures are unavoidable. Also evident is that states are taking very different approaches to the distribution of these funds and that many lessons are being learned as programs are designed, implemented, and evaluated. Our purpose in this paper is therefore to relay early experience with these funds and provide preliminary lessons learned from that experience. It is our hope that this analysis will facilitate learning across states and help state fund managers develop more effective and more coordinated programs. Central to this paper are case studies that provide information on the SBC-funded renewable

    Proposed federal clean energy initiatives and climate legislation have suggested significant increases to federal funding for clean energy deployment and investment. Many states and utilities have over a decade of experience and spend billions of public dollars every year to support EE/RE deployment through programs that reduce the cost of technologies, provide financing for EE/RE projects, offer technical assistance, and educate market participants. Meanwhile, constraints on public expenditures at all levels of government continue to call upon such programs to demonstrate their value. This report reviews the results of these programs and the specific financial incentives and financing tools used to encourage clean energy investment. Lessons from such programs could be used to inform the future application of EE/RE incentives and financing tools. These lessons learned apply to use of distributed resources and the historical focus of these EE/RE programs.

  13. Off-momentum collimation and cleaning in the energy ramp in the LHC

    CERN Document Server

    Quaranta, Elena; Giulini Castiglioni Agosteo, Stefano Luigi Maria

    This Master thesis work has been carried out at CERN in the framework of the LHC (Large Hadron Collider) Collimation project. The LHC is a two-beam proton collider, built to handle a stored energy of 360MJ for each beam. Since the energy deposition from particle losses could quench the superconducting magnets, a system of collimators has been installed in two cleaning insertions in the ring and in the experimental areas. The achievable LHC beam intensity is directly coupled to the beam loss rate and, consequently, to the cleaning eciency of the collimation system. This study analyses the collimation cleaning performance in dierent scenarios inside the accelerator. First, simulations are performed of the transverse losses in the LHC collimation system during the acceleration process. The results are compared with data taken during a dedicated session at the LHC machine. Simulations are also performed to predict the collimation eciency during future operation at higher energy. Furthermore, an investigation of t...

  14. Framework for Evaluating the Total Value Proposition of Clean Energy Technologies

    Energy Technology Data Exchange (ETDEWEB)

    Pater, J. E.

    2006-02-01

    Conventional valuation techniques fail to include many of the financial advantages of clean energy technologies. By omitting benefits associated with risk management, emissions reductions, policy incentives, resource use, corporate social responsibility, and societal economic benefits, investors and firms sacrifice opportunities for new revenue streams and avoided costs. In an effort to identify some of these externalities, this analysis develops a total value proposition for clean energy technologies. It incorporates a series of values under each of the above categories, describing the opportunities for recapturing investments throughout the value chain. The framework may be used to create comparable value propositions for clean energy technologies supporting investment decisions, project siting, and marketing strategies. It can also be useful in policy-making decisions.

Several federal energy clusters were previously identified, including Hampton Roads, Virginia, which was subsequently studied in detail. This study provides an analysis of three additional diverse federal energy clusters. The analysis shows that there are potential sites in various federal energy clusters that could be evaluated further for placement of an integral pressurized-water reactor (iPWR) to support meeting federal clean energy goals.

  19. Alternative Dark Energy Models: An Overview

    2004-01-01

    A large number of recent observational data strongly suggest that we live in a flat, accelerating Universe composed of $\\sim$ 1/3 of matter (baryonic + dark) and $\\sim$ 2/3 of an exotic component with large negative pressure, usually named {\\bf Dark Energy} or {\\bf Quintessence}. The basic set of experiments includes: observations from SNe Ia, CMB anisotropies, large scale structure, X-ray data from galaxy clusters, age estimates of globular clusters and old high redshift galaxies (OHRG's). Such results seem to provide the remaining piece of information connecting the inflationary flatness prediction ($\\Omega_{\\rm{T}} = 1$) with astronomical observations. Theoretically, they have also stimulated the current interest for more general models containing an extra component describing this unknown dark energy, and simultaneously accounting for the present accelerating stage of the Universe. An overlook in the literature shows that at least five dark energy candidates have been proposed in the context of general re...

    Johnson, R. W.

    1978-01-01

    The space solar power concept is concerned with the use of a Space Power Satellite (SPS) which orbits the earth at geostationary altitude. Two large symmetrical solar collectors convert solar energy directly to electricity using photovoltaic cells woven into blankets. The dc electricity is directed to microwave generators incorporated in a transmitting antenna located between the solar collectors. The antenna directs the microwave beam to a receiving antenna on earth where the microwave energy is efficiently converted back to dc electricity. The SPS design promises 30-year and beyond lifetimes. The SPS is relatively pollution free as it promises earth-equivalence of 80-85% efficient ground-based thermal power plant.

  2. Environmental effects of alternative energy policies

    International Nuclear Information System (INIS)

    The exponential increase of the energy consumption has reduced the possibility to pollute air and land so much that the detrimental external effects of economic activities must be regarded in energy modelling. That means to analyse the interdependent connections between the economic system and the environment and to picture the structure of the real system on a mathematical model. To do this, System Dynamics models were developed. Beside the relevant technical variables also sociological variables such as 'public pressure' or 'lobby pressure' were regarded. So it was possible to break open the 'ceteris paribus' assumption of the constant sociological and political influences. The environmental effect of various policies to meet the energy demand were critically examined in simulation runs. It was demonstrated that the pollution of the atmosphere will decrease in the beginning of the 80ies. This is based on the implementation of a new energy technology with a lower pollution and, on the other side, on the increasing amount of pollution control. (orig.)

    Scrap tires that are not recycled through retreading constitute a serious solid-waste problem, but also offer energy-conservation opportunities through their use as: (1) solid fuel (displaced energy = 15,000 Btu/lb or 35 kJ/g); (2) derived fuel and chemical feedstock (11,000 to 23,000 Btu/lb or 25 to 53.5 kJ/g); (3) virgin rubber compound substitute in traditional rubber products (34,000 to 40,000 Btu/lb or 79 to 93 kJ/g); and (4) asphalt additive for paving applications (90,000 Btu/lb or 210 kJ/g). Both the energy of the displaced fuel and material and the energy consumed preparing the tires for the above uses have been included, where possible, in these estimates. Also provided is a summary of the available data on the cost and requisite scale of operation for the various end use processes.

    The Lansing Community College Alternative Energy Center was created with several purposes in mind. The first purpose was the development of educational curricula designed to meet the growing needs of advanced energy companies that would allow students to articulate to other educational institutions or enter this growing workforce. A second purpose was the professional development of faculty and teachers to prepare them to train tomorrow's workforce and scholars. Still another purpose was to design, construct, and equip an alternative energy laboratory that could be used for education, demonstration, and public outreach. Last, the Center was to engage in community outreach and education to enhance industry partnerships, inform decision makers, and increase awareness and general knowledge of hydrogen and other alternative energy technologies and their beneficial impacts on society. This project has enabled us to accomplish all of our goals, including greater faculty understanding of advanced energy concepts, who are now able to convey this knowledge to students through a comprehensive alternative energy curriculum, in a facility well-equipped with advanced technologies, which is also being used to better educate the public on the advantages to society of exploring alternative energy technologies.

    1981-08-01

    A 10-MW solar-thermal generating plant and a 100-MW integrated coal-gasification combined cycle (IGCC) power facility are being built to develop a wide range of renewable, alternative power sources by 1990. The solar-thermal generating plant will use steam at 500 C and 100 kg/sq cm to produce 10 MW of electricity. It consists of a 1818 heliostat array, each weighing 1155 kg and having 12 mirrors which are rotated at either 0.25 deg/min (for sun following) or 22.5 deg/min (for major focusing and defocusing). A master control system allows both fully automatic and manual operation, and a beam-characterization system permits the operator to check the alignment of each heliostat individually. A central receiver, consisting of 24 panels of tubing, produces steam at 500 C and 100 kg/sq cm. The thermal storage unit uses crushed granite to absorb 50 kWht/cu m, allowing the plant to operate after sundown. The IGCC plant integrates the coal-gasification plant and the combined-cycle unit, demonstrating operational flexibility and reliability, load-following capability, and compliance with environmental regulations. The gasifier produces 79,300 cu m/h of a mixture of 51% CO and 36% H at 1370 C,and the gas turbine regenerates 65 MW through its own generator.

  16. Energy rape seed - Non-food alternatives

    International Nuclear Information System (INIS)

    The aim of the project is to evaluate possibilities to use agrobiomass for several energy end use sectors. The reference is common European approach where ethanol and rape seed oil is produced for transportation sector. The production costs are approximately 3 - 4 times higher compared to non taxed refinery price of gasoline and diesel fuel. This is also the case for energy crops compared to peat and coal. For Finnish conditions several other options are studied including technical and economical assessments. Solid fuels in form of energy crops like reed canary grass, salix-SRF and straw are evaluated as a feed to multifuel fluid bed boilers and as a futuristic scenario also for flashpyrolysis oil production. Rape seed oil is tested by Neste Oy as a biocomponent in heating oil and as a biocomponent in diesel fuel in engines by VTT. According to present results about 10 - 20 % rape seed oil can be mixed unprocessed to heating oils. Agrofibre production is studied in a laboratory phase with two advanced cooking methods to produce a high value product as a fraction of a biorefinery. The aim of the project is to identify possible research and development paths for future activities. With present prices no agrobiomass is today economically competitive with other fuels. (author)

  17. Wind energy technology: an option for a renewable clean environment energy. Low impact renewable energy: options for a clean environment and healthy Canadian economy

    International Nuclear Information System (INIS)

    As Canada debates ways to address climate change, the country's low-impact renewable energy industries want to ensure that Canadians are provided with all of the options available to them. Accordingly, they have come together to create Options for a Clean Environment and Healthy Canadian Economy. Recognizing there is no 'silver bullet' solution to climate change, this document identifies an important suite of measures that, along with others, will allow Canada to achieve its long-term economic and environmental goals. The measures described in this document represent an investment in Canada's future. If implemented, they will reduce annual greenhouse gas (GHG) emissions by more than 12 million tonnes (Mt) by the year 2010 (roughly 8% of Canada's reduction target), create thousands of new jobs, and reduce health-care costs by millions of dollars each year. The most significant dividends from these measures, however, will occur after 2010 as a result of having set in motion fundamental changes in the attitudes of Canadians and the nature of the Canadian energy market. By 2020, the spin-off actions prompted by these measures will likely have resulted in GHG reductions twice as great as those achieved in 2010. This document highlights the opportunities associated specifically with Canada's low-impact renewable energy resources. These are non-fossil-fuel resources that are replenished through the earth's natural cycles and have a minimal impact on the environment and human health. They include wind, solar, earth energy, run-of-river hydro and sustainable biomass fuels. These resources can replace fossil fuels in a variety of areas, including electricity and space and water heating. Fuel cells, although not a renewable resource in themselves, are a promising technology that in combination with renewables have the potential to deliver versatile low-impact electricity. The document also identifies opportunities associated with the increased use of passive renewable energy

  19. Energy Revolution. A Sustainable Pathway to a Clean Energy Future for Europe. A European Energy Scenario for EU-25

    International Nuclear Information System (INIS)

    Greenpeace and the Institute of Technical Thermodynamics, Department of Systems Analysis and Technology Assessment of the German Aerospace Center (DLR),have developed a blueprint for the EU energy supply that shows how Europe can lead the way to a sustainable pathway to a clean energy future. The Greenpeace energy revolution scenario demonstrates that phasing out nuclear power and massively reducing CO2-emissions is possible. The scenario comes close to a fossil fuels phase-out by aiming for a 80% CO2 emissions reduction by 2050.The pathway in this scenario achieves this phase-out in a relatively short time-frame without using technological options (such as 'clean coal') that are ultimately dead ends, deflecting resources from the real solutions offered by renewable energy. Whilst there are many technical options that will allow us to meet short-term EU Kyoto targets (-8% GHG by 2010), these may have limited long-term potential. The Greenpeace Energy Revolution Scenario shows that in the long run, renewable energy will be cheaper than conventional energy sources and reduce EU's dependence from world market prices from imported fossil and nuclear fuels.The rapid growth of renewable energy technologies will lead to a large investment in new technologies.This dynamic market growth will result in a shift of employment opportunities from conventional energy-related industries to new occupational fields in the renewable energy industry. Renewable energy is expected to provide about 700,000 jobs in the field of electricity generation from renewable energy sources by 2010

    The joint effort by Polish and American organizations in Krakow has accomplished a great deal in just a few years. In particular, the low emission sources program has had major successes. Poland and America have a lot to learn from each other in the clean and economical use of coal. Both our countries are major producers and users of coal. Both have had to deal with the emissions of particulate and organics from coal combustion. We were fortunate, since our free market economy and democratic government helped us deal with a lot of these problems in the 1950s. In Poland, the freedom to solve these problems has evolved only in the last few years. In the first phase of the program, Polish and American engineers ran combustion tests on boilers and stoves in Krakow. They also performed analyses on the cost and feasibility of various equipment changes. The results of the first phase were used in refining the spreadsheet model to give better estimates of costs emissions. The first phase also included analyses of incentives for proceeding with needed changes. These analyses identified actions needed to create a market for the goods and services which control pollution. Such actions could include privatization, regulation, or financial incentives. The second phase of the program consisted of public meetings in Chicago, Washington, and Krakow. The purpose of the meetings was to inform U.S. and Polish firms about the results of phase 1 and to encourage them to compete to take part in phase 3. The third phase currently underway consists of the commercial ventures that were competitively selected. These ventures were consistent with recommendations unanimously made by the BSC. The three phases of the Polish-American program are discussed.

    This report summarizes task 1 of the Clean Air Heat Pump project - modelling and simulation on energy savings when using the clean air heat pump for ventilation, air cleaning and energy recovery. The total energy consumption of the proposed ventilation systems using clean air heat pump technology was calculated by a theoretical model and compared with the reference ventilation systems (conventional ventilation systems). The energy compared between the two systems includes energy used for heating, cooling and fan. The simulation and energy saving calculation was made for the application of the clean air heat pump in three typical climate conditions, i.e. mild-cold, mild-hot and hot and wet climates. Real climate data recorded from three cities in 2002 was used for the calculation. The three cities were Copenhagen (Denmark), Milan (Italy) and Colombo (Sir Lanka) which represent the above three typical climate zones. For the Danish climate (the mild cold climate), the calculations show that the ventilation system using clean air heat pump technology can save up to 42% of energy cost in winter compared to the conventional ventilation system. The energy saving in summer can be as high as 66% for the ventilation system with humidity control and 9% for the ventilation system without the requirement of humidity control. Since the Danish summer climate is very mild, over 80% of the yearly energy consumption for ventilation is used during winter season. It is, therefore, estimated that more than 35% annual energy saving for ventilation is expected in Denmark using the clean air heat pump ventilation technology. For the mild hot climate, e.g. the Italian climate, the calculations show that up to 63% of the energy saving can be achieved in summer season. For the winter mode, 17% reduction of the energy cost can be expected for the domestic use. For industrial use, the energy cost of the clean air heat pump may not be favourable due to the industrial price of gas in Italy is

  12. Energy and global warming impacts of CFC alternative technologies for foam building insulations

    International Nuclear Information System (INIS)

    Chlorofluorocarbons (CFCS) have been used as blowing agents in foam insulation, as the working fluids in cooling and refrigeration equipment, and as solvents in general and precision cleaning applications since their introduction in the 1930s. The number of applications and volumes of CFCs used grew at a tremendous pace during the 1960s and 1970s, but in the mid-1980s it was confirmed that these extremely useful chemicals contribute to the destruction of stratospheric zone and that they are the primary cause of the CFCs have also been found to be second only to carbon dioxide as a factor causing increased greenhouse warming. These chemicals are being phased out of use rapidly to protect the ozone layer and it is very important that the replacements for CFCs do not result in a net increase in global warming by introducing less efficient processes that lead to higher energy use and increased carbon dioxide emissions. A study was conducted to identify those alternative chemicals and technologies that could replace CFCs in energy related applications before the year 2000, and to assess the total potential impact of those alternatives on global warming. The analysis for this project included an estimate of the direct effects from the release of blowing agents, refrigerants, and solvents into the atmosphere and the indirect effects of carbon dioxide emissions resulting from energy use for commercial and residential building insulation, household and commercial refrigeration, building and automobile air conditioning, and general metal and electronics solvent cleaning. This paper focuses on those aspects of the study relevant to building insulation. In general the hydrofluorocarbon (HFC) and hydrochlorofluorocarbon alternatives for CFCs lead to large and sometimes dramatic reductions in total equivalent warming impact, lifetime equivalent C02 emissions (TEWI). Most of the reductions result from decreased direct effects without significant changes in energy use

    The purposes, objectives and technology path-ways for alternative energy development are discussed with the aim of reaching sustainable energy development in China. Special attention has been paid to alternative power and alternative vehicle fuels. Instead of limiting alternative energy to energy sources such as nuclear and renewable energy, the scope of discussion is extended to alternative technologies such as coal power with carbon capture and sequestration (CCS), electric and hydrogen vehicles. In order to take account of the fact that China's sustainable energy development involves many dimen-sions, a six-dimensional indicator set has been established and applied with the aim of comprehensively evaluating different technology pathways in a uniform way. The ana-lysis reaches the following conclusions: (a) in the power sector, wind power, nuclear power and hydro power should be developed as much as possible, while R&D of solar power and coal power with CCS should be strengthened continuously for future deployment. (b) in the transporta-tion sector, there is no foreseeable silver bullet to replace oil on a large scale within the time frame of 20 to 30 years. To ease the severe energy security situation, expedient choices like coal derived fuels could be developed. However, its scale should be optimized in accordance to the trade-off of energy security benefits, production costs and environmental costs. Desirable alternative fuels (or technologies) like 2nd generation biofuels and electrical vehicles should be the subject of intensive R&D with the objective to be cost effective as early as possible.

    Elk Valley Rancheria; Tribe; renewable energy; energy options analysis. The Elk Valley Rancheria, California ('Tribe') is a federally recognized Indian tribe located in Del Norte County, California, in the northwestern corner of California. The Tribe, its members and Tribal enterprises are challenged by increasing energy costs and undeveloped local energy resources. The Tribe currently lacks an energy program. The Tribal government lacked sufficient information to make informed decisions about potential renewable energy resources, energy alternatives and other energy management issues. To meet this challenge efficiently, the Tribe contracted with Frank Zaino and Associates, Inc. to help become more energy self-sufficient, by reducing their energy costs and promoting energy alternatives that stimulate economic development. Frank Zaino & Associates, Inc. provided a high level economic screening analysis based on anticipated electric and natural gas rates. This was in an effort to determine which alternative energy system will performed at a higher level so the Tribe could reduce their energy model by 30% from alternative fuel sources. The feasibility study will identify suitable energy alternatives and conservation methods that will benefit the Tribe and tribal community through important reductions in cost. The lessons learned from these conservation efforts will yield knowledge that will serve a wider goal of executing energy efficiency measures and practices in Tribal residences and business facilities. Pacific Power is the provider of electrical power to the four properties under review at $ 0.08 per Kilowatt-hour (KWH). This is a very low energy cost compared to alternative energy sources. The Tribe used baseline audits to assess current and historic energy usage at four Rancheria owned facilities. Past electric and gas billing statements were retained for review for the four buildings that will be audited. A comparative assessment of the various

    The generation of electricity in Brazil is concentrated in hydroelectric generation, renewable and clean source, but that does not satisfy all the demand and leads to necessity of a supplementary thermal sources portion. Considering the predictions of increase in demand for electricity in the next years, it becomes necessary to insert new sources to complement the production taking into account both the volume being produced and the needs of environmental preservation. Thus, nuclear power can be considered a potential supplementary source for electricity generation in Brazil as well as the country has large reserves of fissile material, the generation emits no greenhouse gases, the country has technological mastery of the fuel cycle and it enables the production of large volumes of clean energy. The objective of this study is to demonstrate the potential of nuclear energy in electricity production in Brazil cleanly and safely, ensuring the supplies necessary to maintain the country's economic growth and the increased demand sustainable. For this, will be made an analysis of economic and social indicators of the characteristics of our energy matrix and the availability of our sources, as well as a description of the nuclear source and arguments that justify a higher share of nuclear energy in the matrix of the country. Then, after these analysis, will notice that the generation of electricity from nuclear source has all the conditions to supplement safely and clean supply of electricity in Brazil. (author)

    International Nuclear Information System (INIS)

    Antigonish is located along the northeastern shores of mainland Nova Scotia, bounded by the Gulf of St. Lawrence and the Bay of St. George. This document investigated the local effects of climate change in the area and on known renewable energy alternatives that are currently being used around the world, and how those same options could be applied to Antigonish. Examples of each energy option were applied to industrial, institutional and residential sectors, and the local effects of climate change were also examined. The renewable energy alternatives were probed against a variety of criteria and were compared on a cost basis. Focusing on the resources available in Antigonish, each energy alternative was rated on a scale of 1 to 10, with one being the best option. The top 5 renewable energy alternatives for Antigonish were identified as: (1) geothermal heating through a heat pump; (2) solar thermal for small business, institutional or residential applications; (3) small scale wind for commercial, institutional or farm practices; (4) biomass plants for secondary material, particularly forestry residue; and, (5) low-head hydro generating stations. The broad range of uses for these renewable energy resources were described. In order to reduce dependence on traditional energy sources, the examples described the potential changes for industry, institutional and residential applications. 74 refs., 6 figs.

The use of alternative energies in this industry has been in place for a while now. This paper discusses the application of various alternative energy sources to assist powering the Goodwyn Alpha (A Platform, located on the North West Shelf (NWS of Australia. The three alternative energy sources under discussion are: wind, wave and solar. The extraction devices used are the Horizontal and Vertical-Axis Wind Turbines - for wind; Pelamis, PowerBuoy and Wave Dragon - for wave; and the solar parabolic dish of SunBeam and Photovoltaic (PV cells of SunPower - for solar. These types of devices are installed within the same offshore platform area. Technical, environmental and economic aspects are taken into consideration before the best selection is made. The results showed that PowerBuoy used for wave energy, is the best device to be used on offshore platforms where operators could save up to 9% of power; $603,083 of natural gas; and 10,848 tonnes of CO2 per year.

  14. Clean Energy for Tomorrow: Towards Zero Emission and Carbon Free Future: A Review

    Full Text Available Fuel cell technology using hydrogen energy is an advanced green energy technology for the future use. This is green, sustainable, clean and very environmental friendly. Green house gases emission from industrial activities has been proven beyond doubt as the main cause of global warming and climate changes. The finite world energy supply that consists nearly 90% of fossil fuel which is depleted; an energy crisis because of widening fossil fuel production and demand gaps. Many nations responded to anticipate energy crisis by diversifying their fuel resources to include renewable and alternative energy and developing green energy technology for the future. Despite political announcements on renewable energy, fossil fuels will continue to dominate energy resources for some time to come and carbon emission will increase but global nuclear energy expansion is uncertain because of international tensions and general public fears of another Chernobyl or Fogoshima disasters or a nuclear terrorist attack. Biofuels are plagued by the conflict between crops for fuel and crops for food and there is a shift of interest towards crop biomass wastes. The further expansion of hydrogen energy is constrained by costs and safety in hydrogen transport and storage. Fuel cell research and development has shifted from older AFC, PAFC and MCFC whose entry into the market were stalled by intractable operational and durability problems, to more promising PEMFC, DMFC and SOFC. A new type of fuel cell, the microbial fuel cell (MFC is also gaining some attention because of sustainable way of simultaneously reducing BOD and COD of wastewater and provide power; combined wastewater treatment and power (CWTP. The main thrust in PEMFC research and development is cost reduction of membrane and electrocatalyst by substitution of cheap and more efficient organic-inorganic nanocomposite membranes and nanoinorganic electrocatalyst as well as lower electrocatalyst loading and cost

  16. Locally Appropriate Energy Strategies for the Developing World: A focus on Clean Energy Opportunities in Borneo

    Science.gov (United States)

    Shirley, Rebekah Grace

    This dissertation focuses on an integration of energy modeling tools to explore energy transition pathways for emerging economies. The spate of growth in the global South has led to a global energy transition, evidenced in part by a surge in the development of large scale energy infrastructure projects for the provision of reliable electricity service. The rational of energy security and exigency often usher these large scale projects through to implementation with minimal analysis of costs: social and environmental impact, ecological risk, or opportunity costs of alternative energy transition pathways foregone. Furthermore, development of energy infrastructure is inherently characterized by the involvement of a number of state and non-state actors, with varying interests, objectives and access to authority. Being woven through and into social institutions necessarily impacts the design, control and functionality of infrastructure. In this dissertation I therefore conceptualize energy infrastructure as lying at the intersection, or nexus, of people, the environment and energy security. I argue that energy infrastructure plans and policy should, and can, be informed by each of these fields of influence in order to appropriately satisfy local development needs. This case study explores the socio-techno-environmental context of contemporary mega-dam development in northern Borneo. I describe the key actors of an ongoing mega-dam debate and the constellation of their interaction. This highlights the role that information may play in public discourse and lends insight into how inertia in the established system may stymie technological evolution. I then use a combination of power system simulation, ecological modeling and spatial analysis to analyze the potential for, and costs and tradeoffs of, future energy scenarios. In this way I demonstrate reproducible methods that can support energy infrastructure decision making by directly addressing data limitation barriers. I

    Replacing inefficient kerosene lighting with electric lighting or other clean alternatives can rapidly achieve development and energy access goals, save money and reduce climate warming. Many of the 250 million households that lack reliable access to electricity rely on inefficient and dangerous simple wick lamps and other kerosene-fueled light sources, using 4 to 25 billion liters of kerosene annually to meet basic lighting needs. Kerosene costs can be a significant household expense and subsidies are expensive. New information on kerosene lamp emissions reveals that their climate impacts are substantial. Eliminating current annual black carbon emissions would provide a climate benefit equivalent to 5 gigatons of carbon dioxide reductions over the next 20 years. Robust and low-cost technologies for supplanting simple wick and other kerosene-fueled lamps exist and are easily distributed and scalable. Improving household lighting offers a low-cost opportunity to improve development, cool the climate and reduce costs.

  4. The contribution of foreign direct investment to clean energy use, carbon emissions and economic growth

    International Nuclear Information System (INIS)

    The paper investigates the contributions of foreign direct investment (FDI) net inflows to clean energy use, carbon emissions, and economic growth. The paper employs cointegration tests to examine a long-run equilibrium relationship among the variables and fixed effects models to examine the magnitude of FDI contributions to the other variables. The paper analyzes panel data of 19 nations of the G20 from 1971 to 2009. The test results indicate that FDI has played an important role in economic growth for the G20 whereas it limits its impact on an increase in CO2 emissions in the economies. The research finds no compelling evidence of FDI link with clean energy use. Given the results, the paper discusses FDI's potential role in achieving green growth goals. - Highlights: ► FDI inflows strongly lead to economic growth in the G20. ► FDI inflows lead to an increase in energy use in the G20. ► FDI inflows are in no relation to CO2 emissions in the G20. ► FDI inflows are in no relation to clean energy use in the G20. ► Economic growth is in negative relation to CO2 emissions in the G20

  5. Financing clean energy development in the emerging economies: the need for innovation

    International Nuclear Information System (INIS)

    The World Energy Council's Commission ''Energy for Tomorrow's World'' points out that the emerging economies (the developing countries and the economies in transition) face increasingly daunting challenges in meeting their energy service requirements and in ensuring their energy needs are met in an environmentally-sustainable manner. Rising to the environmental challenge will require the diffusion of cleaner and more efficient energy production, transportation and end-use technologies. Greater efficiency is required if only to reduce growing shortages in meeting national power requirements. Against this backdrop, this article will examine: whether or not the funding needs of clean energy development in the emerging economies are being met; and what kinds of financial innovation might be required to accelerate the diffusion of cleaner energy technologies.

    A set of density-functional calculations for clean and O-covered Al(111) are presented. At low O coverages the potential energy surface (PES) of chemisorbed O is investigated. The PES indicates large barriers (0.8 eV) against O diffusion and a large corrugation of the equilibrium O height over...... the Al(111) while only a moderate energy gain (5 eV per atom) is found upon Oz dissociation over the surface. The possible existence of ''hot'' O adatoms after O-2 dissociation is discussed on the basis of the presented PES and existing dynamical simulations on model potentials. At high O coverages...... an attractive O-O interaction is identified together with an enhancement in the dipole moment induced per O atom. Finally, Tersoff-Hamann-type scanning tunneling microscopy (STM) topographs are derived based on the calculated one-electron wave functions and spectra. For the clean Al(111) a theoretical STM...

    The project has been designed to reduce energy consumption for air purification by 30% while having a payback period of maximum 3 years. The project has achieved very significant results which are far above the target. Particularly satisfying is the wide range of new components that are launched in late 2012. By implementing the newly developed system at 100% cleaning (LPC 13 ventilators and Dynamic multistep control) in relation to Best Practice (SKOV's original system with DA600 fans) in a concrete pigsty, a saving of 61% and a simple payback of 1.7 years is achieved. Similarly, it is found that the energy used for pump operation can be reduced by 37% with the new Dynamic sprinkling control. At 20% cleaning a potential saving of 15% per year and a payback period of between 0 and 5 years was found, which is dependent on the desired performance as the capacities in the bio-filter's upper capacity range between 26 thousand to 30 thousand m3 / h entails costs for an additional extraction unit in the new solution. Furthermore, the newly developed components proved highly suitable for standard installations without air cleaning where a savings potential is 53% and the payback period 1.5 years. Product-wise, the project formed the basis for the development of: 1. New energy-efficient ventilation units (LPC11, 12,13) that are suitable for air purification; 2. A new energy-saving control principle (Dynamic Multi-Step) which is particularly suitable for low-energy ventilators; 3. A new energy-saving flow measurement system for ventilating ducts (Dynamic air to the central exhaust); 4. An energy-saving pressure control in common ducts (pressure control as a function of outside temperature); 5. Proposal for a new energy-saving pump operation for sprinkling of biological filters (Dynamic sprinkling). (LN)

  9. Long-term alternative energy R and D strategies

    International Nuclear Information System (INIS)

    Within the coming decades a transition must be initiated from oil and gas to 'unlimited' primary energy sources, i.e., nuclear and solar energy. Ever more expensive fossil energy forms will have to provide for an intermediary solution to the growing global energy demand. While a rather clear-cut picture of the energy problem has emerged on the global level, a straightforward translation to the national or even to the company level is not available. The current study contract between the European Economic Community and the International Institute for Applied Systems Analysis (IIASA) is a first exercice designed to transfer the global results to the intermediary level of the ''Subregion'' of the European Community. In operational terms the contract aims at identifying long-term (up to 2030) alternative energy R and D strategies for twelve European countries that would be consistent with the global scenarios, identified by IIASA

    The alternative forms of energy transmission from ocean thermal energy conversion (OTEC) plants are compared. The chemical energy carriers considered are the following: gaseous and liquid hhydrogen, liquid ammonia, methanol, gasoline, and methane. The assessment assumes that each of the above energy carriers were transported by barge and/or pipeline. The delivered costs of energy using the above chemical energy carriers are compared for different offshore distances. When comparing the delivered cost of chemical energy with transmission of electricity by submarine cables, the outputs are converted to a common form. Thus, in addition to presenting the production and transportation costs and overall energy efficiency of the chemical energy carriers, we have provided a discussion of the equipment, capital and operating costs, and efficiencies of converting the delivered hydrogen and ammonia into electricity. A concise technical assessment and economic analysis of components associated with the conversion, storage, transportation, and shore-based receiving facilities for the conversion of OTEC mechanical energy to chemical energy, and in some cases conversion of delivered chemical energy to electricity are presented.

    1. To evaluate the role of new energy sources in meeting future needs it is necessary to choose the correct context with regard to pattern of energy usage and quality as well as quantity of energy required; 2. present official forecasts of exponential growth in energy demand are almost certainly wildly exaggerated, particularly in the electricity sector; 3. official statements identify an anticipated 'energy gap' which can be filled only with nuclear electricity; the data do not support any such conclusion, either as regards the 'gap' or as regards the capability of filling it with nuclear electricity; 4. the fast breeder reactor, the focus of future UK planning, has a long and depressing history everywhere it has been developed; its technical and economic characteristics seem likely to make virtually all other options cheaper, easier and safer; 5. nuclear fusion, if it can be developed at all, may remove an essential constraint on the amount of man-made energy added to the planetary system; 6. research and development of solar, wind, tidal and wave energy all warrant far more substantial support, although their wide-scale introduction will require many years; 7. nuclear proponents have implied that the choice is either nuclear electricity or sun, wind and waves; such an implication is without substance, since it ignores the reborn UK coal industry; 8. the UK should undertake a major programme of development of small-scale total-energy coal-fired fluidized-bed systems, on the urban sites of existing CEGB stations due for shut-down; 9. the public should insist that the planners look at the real world and plan accordingly.

    1989-07-01

    As a result of the Montreal Protocol that limits the production of ozone-depleting refrigerants, manufacturers are searching for alternatives to replace the R12 that is presently used in residential refrigerator-freezers. Before an alternative can be selected, several issues must be resolved. Among these are energy impacts, system compatibility, cost, and availability. In an effort to determine the energy impacts of some of the alternatives, energy consumption tests were performed in accordance with section 8 of the Association of Home Appliance Manufacturers (AHAM) standard for household refrigerators and household freezers. The results are presented for an 18 cubic foot (0.51 cubic meter), top-mount refrigerator-freezer with a static condenser using the following refrigerants: R12, R500, R12/Dimethyl-ether (DME), R22/R142b, and R134a. Conclusions from the AHAM test are that R500 and R12 /DME have a reduced energy consumption relative to R12 when replaced in the test unit with no modifications to the refrigeration system. Run times were slightly lower than R12 for both refrigerants indicating a higher capacity. While the R134a and R22/R142b results were less promising, changes to the refrigeration system, such as a different capillary tube or compressor, may improve performance.

  20. Survey on alternative energy for industrial processes in Indonesia

    International Nuclear Information System (INIS)

    In consequence of the national industrial development, it is necessary to supply a lot of energy. This paper presented a discussion about the option of supplying nuclear processed heat as alternative energy sources for industry especially in Java island. The electrical energy requirement can be estimated rising. The stock and the requirement of energy in Indonesia is unbalance. If the oil production rate is constant, such as that of today, it can be estimated that the oil stock would be over in 20 years. The country is trying to difertify its source of energy and reduce its dependence on oil. High Temperature Reactor (HTR) produces electric and also heat at various temperature in the form of steam and gas. Heat processes from a high temperature reactor, could be used in industry for supplying heat for coal hidroforming, gasification of coal, metal annealing, petrochemical hydrogenation, distillation, purification of petrochemicals, evaporation, water heat, etc. (author). 8 refs, 1 fig., 5 tabs

    This study was conducted to develop market intelligence related to clean energy technologies in Northern California, including both commercial and demonstration technologies. The study was developed as a tool for exploring engagement between Canadian and Californian businesses and partnering opportunities. The study examined technologies for solar power and photovoltaics; hydrogen and fuel cells; and waste-to-energy. A list of more than 150 organizations, government agencies, business associations, and utilities was prepared. The survey also included the establishment of contact points with large facilities, public spaces, bus fleets, and major capital projects. Fifty-nine interviews were also conducted as part of the study. Results of the study indicated that the biggest challenge concerning most individuals was the need to reduce energy consumption while maintaining reliability. Many interviewees expressed an interest in operating waste-to-energy facilities. Fifty interviewees indicated that they were planning to use or already used solar technologies. An analysis of clean energy needs was also included. The study indicated that many local governments are reluctant to embrace new, highly visible technologies. Only sophisticated organizations with unique energy demands have considered the use of fuel cell technologies. 1 fig

    2012-08-01

    In 2010 and 2011, Republicans and Democrats proposed mandating clean power generation in the electricity sector. To evaluate public support for a national clean energy standard (NCES), we conducted a nationally representative survey that included randomized treatments on the sources of eligible power generation and programme costs. We find that the average US citizen is willing to pay US$162 per year in higher electricity bills (95% confidence interval: US$128-260), representing a 13% increase, in support of a NCES that requires 80% clean energy by 2035. Support for a NCES is lower among non-whites, older individuals and Republicans. We also employ our statistical model, along with census data for each state and Congressional district, to simulate voting behaviour on a NCES by Members of Congress assuming they vote consistently with the preferences of their median voter. We estimate that Senate passage of a NCES would require an average household cost below US$59 per year, and House passage would require costs below US$48 per year. The results imply that an `80% by 2035' NCES could pass both chambers of Congress if it increases electricity rates less than 5% on average.

  6. Understanding and accepting fusion as an alternative energy source

    International Nuclear Information System (INIS)

    Fusion, the process that powers our sun, has long promised to be a virtually inexhaustible source of energy for mankind. No other alternative energy source holds such bright promise, and none has ever presentd such formidable scientific and engineering challenges. Serious research efforts have continued for over 30 years in an attempt to harness and control fusion here on earth. Scientists have made considerable progress in the last decade toward achieving the conditions required for fusion power, and recent experimental results and technological progress have made the scientific feasibility of fusion a virtual certainty. With this knowledge and confidence, the emphasis can now shift toward developing power plants that are practical and economical. Although the necessary technology is not in hand today, the extension to an energy producing system in 20 years is just as attainable as was putting a man on the moon. In the next few decades, the world's population will likely double while the demand for energy will nearly quadruple. Realistic projections show that within the next generation a significant fraction of our electric power must come from alternative energy sources. Increasing environmental concerns may further accelerate this timetable in which new energy sources must be introduced. The continued development of fusion systems to help meet the energy needs of the future will require greater public understanding and support of this technology. The fusion community must do more to make the public aware of the fact that energy is a critical international issue and that fusion is a viable and necessary energy technology that will be safe and economical. 12 refs., 8 figs

    Traditionally, DNA extracts from biological evidence items have been concentrated and rinsed using microdialysis filtration units, including the Centricon(®) and Microcon(®) centrifugal filter devices. As an alternative to microdialysis filtration, we present an optimized method for using NucleoSpin(®) XS silica columns to concentrate and clean-up aqueous extracts from the organic extraction of DNA from biological samples. The method can be used with standard organic extraction and dithiothreitol (DTT)-based differential extraction methods with no modifications to these methods prior to the concentration and clean-up step. Extracts from laboratory-prepared bloodstains, saliva and semen stains have been successfully amplified with both qPCR and STR assays. Finally, the total time to process a set of samples with the NucleoSpin(®) XS column is approximately 30 min vs. approximately 1.5h with the Centricon(®) YM-100 filter device.

  8. The Clean-Development Mechanism, stochastic permit prices and energy investments

    International Nuclear Information System (INIS)

    We analyze the impact on energy investments stemming from different emission permit classes, by considering permits that are allocated inside the European Emission Trading Scheme and secondary Certified Emission Reduction (sCER) permits originating from the Clean Development Mechanism. One price taking firm which is subject to emission regulation has the choice to invest in gas or wind power plant. The firm faces uncertainty regarding stochastically evolving permit prices, while it receives a premium on the electricity price for wind energy. As a first step, we determine the value of the option to invest into a gas power plant over time. Then, we calculate the investment probability of a gas power investment in a range of policy scenarios. We find that allowing the usage of sCER permits in the present policy framework has a positive impact on gas power investment. Decoupling the price processes has a similar effect. If the quota of sCER permits is doubled, the decrease in the investment probability for wind power is large. We carry out sensitivity tests for different parameter values, and find that investment behavior changes significantly with differing interest rates, the wind energy premium and volatility. - Highlights: • We model the impact of two CO2 permit classes on energy investments. • We present a real-options framework accounting for uncertainty. • Clean Development Mechanism permits have a negative influence on investment into renewable energy. • Interest rate and volatility values have a strong impact on the results

    The absence of reliable access to clean energy and the services it provides imposes a large disease burden on low-income populations and impedes prospects for development. Furthermore, current patterns of fossil-fuel use cause substantial ill-health from air pollution and occupational hazards. Impending climate change, mainly driven by energy use, now also threatens health. Policies to promote access to non-polluting and sustainable sources of energy have great potential both to improve public health and to mitigate (prevent) climate disruption. There are several technological options, policy levers, and economic instruments for sectors such as power generation, transport, agriculture, and the built environment. However, barriers to change include vested interests, political inertia, inability to take meaningful action, profound global inequalities, weak technology-transfer mechanisms, and knowledge gaps that must be addressed to transform global markets. The need for policies that prevent dangerous anthropogenic interference with the climate while addressing the energy needs of disadvantaged people is a central challenge of the current era. A comprehensive programme for clean energy should optimise mitigation and, simultaneously, adaption to climate change while maximising co-benefits for health--eg, through improved air, water, and food quality. Intersectoral research and concerted action, both nationally and internationally, will be required. PMID:17868819

  12. Geothermal energy resource: an alternative to energy source in Kenya

    Energy Technology Data Exchange (ETDEWEB)

    1999-07-01

    Kenya energy potential lies in the use of geothermal resources. Currently the country relies heavily on imported petroleum fuels and biomass. Electricity is derived from hydropower which is currently 570 MW with an additional 30MW imported from Uganda; thermal 136MW and geothermal 45MW. Geothermal potential in Kenya currently stands at 2000MW. Other potential areas include Suswa, Longonot, Menengai, Korosi, Paka, Silai, Emurungogolak, Namarunu, Barrier and Homa Hill. Geothermal exploration is taking place at Olkaria, Eburru and L. Bogoria, all in the Kenya rift valley. Other potential areas include the Nyanza rift. Exploitation of this potential would meet the current and future electricity needs of the country. Geothermal resources is a relatively environmentally friendly source of energy. The technology of production is well developed to minimise gas and water vapour emissions into the atmosphere. For example, at Olkaria Geothermal Station, the production system has a cooling tower where hot water steam mixture is cooled. Only 5% of the water, representing 70% of the condensed steam is lost from the cooling tower through evaporation. The cooled water, at a temperature of 23degC is injected back into the well for the recharge of the steam reservoir. (Author)

  13. Making Clean Energy with a Kerr Black Hole: A Tokamak Model for Gamma-Ray Bursts

    Science.gov (United States)

    Li, Li-Xin

    2000-11-01

    In this paper we present a model for making clean energy with a Kerr black hole. Consider a Kerr black hole with a dense plasma torus spinning around it. A toroidal electric current flows on the surface of the torus, which generates a poloidal magnetic field outside the torus. On the surface of the torus the magnetic field is parallel to the surface. The closed magnetic field lines winding around the torus compress and confine the plasma in the torus, as in the case of tokamaks. Although it is unclear whether such a model is stable, we look into the consequences if the model is stable. If the magnetic field is strong enough, the baryonic contamination from the plasma in the torus is greatly suppressed by the magnetic confinement, and a clean magnetosphere of electron-positron pairs is built up around the black hole. Since there are no open magnetic field lines threading the torus and no accretion, the power of the torus is zero. If some magnetic field lines threading the black hole are open and connect with loads, clean energy can be extracted from the Kerr black hole by the Blandford-Znajek mechanism. The model may be relevant to gamma-ray bursts. The energy in the Poynting flux produced by the Blandford-Znajek mechanism is converted into the kinetic energy of the electron-positron pairs in the magnetosphere around the black hole, which generates two oppositely directed jets of electron-positron pairs with superhigh bulk Lorentz factors. The jets collide and interact with the interstellar medium, which may produce gamma-ray bursts and the afterglows.

  14. Outreach and education to ensure a clean energy future for all - 59339

    International Nuclear Information System (INIS)

    As the nuclear industry continues to grow throughout the world, we find that support from government officials, local business leaders and the general public is becoming more and more important. In order to help raise awareness and inform these various publics, AREVA expanded upon a best practice from its worldwide operations and recently established a Community Advisory Council in the United States. The member organizations represent a variety of grassroots and minority organizations from across the United States and are active in various ways in local, state and federal arenas. AREVA's objective for the Council is simple - listen to concerns, engage in dialogue and raise awareness about the intrinsic link existing between energy, CO2 emissions, global warming, and economic growth, so these same people can make decisions when it comes to energy sources in the future. We want our members to help us better understand their communities, listen to their concerns and answer their questions openly and honestly. AREVA understands that this outreach and education are just the first steps toward helping clean energy sources grow. We must maintain regular dialog and operate in a safe manner, because in the long run, it is these community members who will ensure energy security for the country. And it is only by working together as an industry that we can ensure a safe, clean air future for generations to come, no matter where in the world we live. (authors)

    A planning study was made for DOE on alternate fuels for non-highway transportation (aircraft, rail, marine, and pipeline). The study provides DOE with a recommendation of what alternate fuels may be of interest to non-highway transportation users from now through 2025 and recommends R and D needed to allow non-petroleum derived fuels to be used in non-highway transportation. Volume III contains all of the references for the data used in the preliminary screening and is presented in 4 subvolumes. Volume IIIA covers the background information on the various prime movers used in the non-highway transportation area, the physical property data, the fuel-prime mover interaction and a review of some alternate energy forms. Volume IIIB covers the economics of producing, tranporting, and distributing the various fuels. Volume IIIC is concerned with the environment issues in production and use of the fuels, the energy efficiency in use and production, the fuel logistics considerations, and the overall ratings and selection of the fuels and prime movers for the detailed evaluation. Volume IIID covers the demand-related issues.

    Building Energy Performance Standards (BEPS) were mandated by the Energy Conservation Standards for New Buildings Act of 1976 (Title III of Energy Conservation and Production Act) to promote energy efficiency and the use of renewable resources in new buildings. The report analyzes alternative Federal strategies and their component policy instruments and recommends a strategy for achieving the goals of the Act. The concern is limited to space conditioning (heating, cooling, and lighting) and water heating. The policy instruments considered include greater reliance on market forces; research and development; information, education and demonstration programs; tax incentives and sanctions; mortgage and finance programs; and regulations and standards. The analysis starts with an explanation of the barriers to energy conservation in the residential and commercial sectors. Individual policy instruments are then described and evaluated with respect to energy conservation, economic efficiency, equity, political impacts, and implementation and other transitional impacts. Five possible strategies are identified: (1) increased reliance on the market place; (2) energy consumption tax and supply subsidies; (3) BEPS with no sanctions and no incentives; (4) BEPS with sanctions and incentives (price control); and (5) BEPS with sanctions and incentives (no price controls). A comparative analysis is performed. Elements are proposed for inclusion in a comprehensive strategy for conservation in new buildings. (MCW)

    Energy production in Laos is still dominated by traditional fuels. Fuelwood in the main source of energy and most of the energy is consumed at households for cooking. Increase in the number of cars and motorbikes is rapidly increasing the use of imported petroleum products. Electrification is one of the central targets of the Lao government. The electrification rate has increased fast in Laos and in the year 2010 over 70 % households had electricity supply. The target is to have 90 % access to electricity by the year 2020. The World Bank regards the electrification of Lao PDR to be a success story. This paper deals with the present and future energy consumption in Laos. First the historical trends of energy use in different sectors are analysed. The future scenarios are constructed using LaoLinda model. Four different future alternative development paths are analysed using the model results. The energy use data source for the analysis is from the Ministry of Energy and Mines (MEM) of Lao PDR. Economic and other data is from the Department of Statistics of Lao PDR.

    Climate change will have far reaching impacts that the citizens of tomorrow will need to be prepared to address. In order for the citizens of tomorrow to be prepared, there is a clear need to support teachers in improving their understanding of the climate system and give them the resources to help their students develop that understanding. CLEAN (http://cleanet.org) is a National Science Digital Library (http://www.nsdl.org) project that is stewarding a collection of resources for teaching climate and energy science in grades 6-16. The collection contains classroom activities, lab demonstrations, visualizations, simulations, videos, and more. We have implemented a series of nine interactive webinars (iWebinars), each of which focuses on an aspect of the Essential Principles of Climate Science, pairs a scientist and a teacher to convey the science and how to teach that science using the vetted resources in the CLEAN collection, and gives the participants the opportunity to ask questions and discuss with the presenters and each other how they would use the resources in their classrooms and what else they would need to effectively teach the topic under discussion. The iWebinars were recorded and posted to the CLEAN portal (http://cleanet.org/clean/community/webinars/index.html) so that the participants and others can view them in the future. In this presentation, we will describe the scope and structure of the iWebinars; how the scientist's and teacher's presentations were coordinated to most effectively help the participants learn both the science and how to best convey it to their students; and how we involved the teachers in discussions to deepen their engagement and learning.

    2011-06-01

    Over ninety percent of Mongolia's energy load is run through the Central Energy System. This primary grid provides Mongolia's capital, Ulaanbaatar, with the power it uses to function. In the first half of 2010 the Central Energy System managed 1739.45 million kWhs, a 4.6 percent increase from 2009. If this growth rate continues, by 2015 Ulaanbaatar's three power plants will be unable to generate enough heat and electricity to meet the city's needs. Currently, plans have been proposed to rehabilitate the aging coal power plants. However, rising maintenance costs and growing emission levels make the long-term sustainability of this solution uncertain. The following paper analyzes the capital, maintenance, and decommissioning costs associated with the current rehabilitation plans and compares them with a nuclear alternative.

    be unused and convert it to electricity or useful thermal energy. Recycled energy produces no or little increase in fossil fuel consumption and pollutant emissions. Examples of energy recycling methods include industrial gasification technologies to increase energy recovery, as well as less traditional CHP technologies, and the use of energy that is typically discarded from pressure release vents or from the burning and flaring of waste streams. These energy recovery technologies have the ability to reduce costs for power generation. This report is a preliminary study of the potential contribution of this ''new'' generation of clean recycled energy supply technologies to the power supply of the United States. For each of the technologies this report provides a short technical description, as well as an estimate of the potential for application in the U.S., estimated investment and operation costs, as well as impact on air pollutant emission reductions. The report summarizes the potential magnitude of the benefits of these new technologies. The report does not yet provide a robust cost-benefit analysis. It is stressed that the report provides a preliminary assessment to help focus future efforts by the federal government to further investigate the opportunities offered by new clean power generation technologies, as well as initiate policies to support further development and uptake of clean power generation technologies.

    2007-04-20

    This technical memorandum (TM) describes the technology requirements for three alternative energy technologies for which pilot and/or commercial projects on the U.S. Outer Continental Shelf (OCS) are likely to be proposed within the next five to seven years. For each of the alternative technologies--wind, wave, and ocean current--the TM first presents an overview. After each technology-specific overview, it describes the technology requirements for four development phases: site monitoring and testing, construction, operation, and decommissioning. For each phase, the report covers the following topics (where data are available): facility description, electricity generated, ocean area (surface and bottom) occupied, resource requirements, emissions and noise sources, hazardous materials stored or used, transportation requirements, and accident potential. Where appropriate, the TM distinguishes between pilot-scale (or demonstration-scale) facilities and commercial-scale facilities.

  2. An international partnership approach to clean energy technology innovation: Carbon capture and storage

    Yang, Xiaoliang

    Is a global research partnership effective in developing, deploying, and diffusing clean energy technologies? Drawing on and extending innovation system studies, this doctoral dissertation elaborates an analytical model for a global technology learning system; examines the rationales, mechanisms, and effectiveness of the United States-- China Clean Energy Research Center Advanced Coal Technology Consortium (CERC-ACTC); and analyzes government's role in developing and implementing carbon capture and storage technologies in the United States (U.S.) and China. Studies have shown that successful technology innovation leads to economic prosperity and national competence, and prove that technology innovation does not happen in isolation but rather within interactive systems among stakeholders. However, the innovation process itself remains unclear, particularly with regard to interactive learning among and between major institutional actors, including technology developers, regulators, and financial organizations. This study seeks to advance scholarship on the interactive learning from the angle of global interactive learning. This dissertation research project seeks, as well, to inform policy-makers of how to strengthen international collaboration in clean energy technology development. The U.S.--China CERC-ACTC announced by Presidents Obama and Hu in 2009, provided a unique opportunity to close this scholarly gap. ACTC aimed to "advance the coal technology needed to safely, effectively, and efficiently utilize coal resources including the ability to capture, store, and utilize the emissions from coal use in both nations " through the joint research and development by U.S. and Chinese scientists and engineers. This dissertation project included one-year field research in the two countries, with in-depth interviews of key stakeholders, a survey of Consortium participants, analysis of available data, and site visits to collaborative research projects from 2013-2014.

    1979-01-01

    As various alternative energy technologies such as photovoltaics, wind, fuel cells, and batteries are emerging as potential sources of energy for the future, the need arises for development of suitable power-conditioning systems to interface these sources to their respective loads. Since most of these sources produce dc electricity and most electrical loads require ac, an important component of the required power-conditioning units is a dc-to-ac inverter. The discussions deal with the development of power conditioners for each alternative energy technology. Discussion topics include assessments of current technology, identification of operational requirements with a comparison of requirements for each source technology, the identification of future technology trends, the determination of mass production and marketing requirements, and recommendations for program direction. Specifically, one working group dealt with source technology: photovoltaics, fuel cells and batteries, and wind followed by sessions discussing system size and application: large grid-connected systems, small grid-connected systems, and stand alone and dc applications. A combined group session provided an opportunity to discuss problems common to power conditioning development.

  5. Renewable Energy Investment in Emerging Markets: Evaluating Improvements to the Clean Development Mechanism

    2014-06-01

    Full Text Available In the past, industrialized countries have invested in or financed numerous renewable energy projects in developing countries, primarily through the Clean Development Mechanism (CDM of the Kyoto Protocol. However, critics have pointed to its bureaucratic structure, problems with additionality and distorted credit prices as ill-equipped to streamline renewable energy investment. In this paper, we simulate the impact of policy on investment decisions on whether or not to invest in wind energy infrastructure in India, Brazil and China. Data from 2,578 past projects as well as literature on investor behaviour is used to inform the model structure and parameters. Our results show that the CDM acts differently in each country and reveal that while streamlining the approval process and reconsidering additionality can lead to non-trivial increase in total investment, stabilizing policy and decreasing investment risk will do the most to spur investment.

  6. Alternate Energy Sources for Thermalplastic Binding Agent Consolidation

    Energy Technology Data Exchange (ETDEWEB)

    Frame, B.J.

    1999-01-01

    A study was conducted to investigate microwave and electron beam technologies as alternate energy sources to consolidate fiber coated with a thermoplastic binding agent into preforms for composite molding applications. Bench experiments showed that both microwave and electron beam energy can produce heat sufficient to melt and consolidate a thermoplastic binding agent applied to fiberglass mat, and several two- and three-dimensional fiberglass preforms were produced with each method. In both cases, it is postulated that the heating was accomplished by the effective interaction of the microwave or electron beam energy with the combination of the mat preform and the tooling used to shape the preform. Both methods contrast with conventional thermal energy applied via infrared heaters or from a heated tool in which the heat to melt the thermoplastic binding agent must diffuse over time from the outer surface of the preform toward its center under a thermal gradient. For these reasons, the microwave and electron beam energy techniques have the potential to rapidly consolidate thick fiber preforms more efficiently than the thermal process. With further development, both technologies have the potential to make preform production more cost effective by decreasing cycle time in the preform tool, reducing energy costs, and by enabling the use of less expensive tooling materials. Descriptions of the microwave and electron beam consolidation experiments and a summary of the results are presented in this report.

  8. Depletion of energy or depletion of knowledge alternative use of energy resources

    International Nuclear Information System (INIS)

    This research paper is about the depletion of Energy resources being a huge problem facing the world at this time. As available energy sources are coming to a shortage and measures are be taken in order to conserve the irreplaceable energy resources that leads to sustainability and fair use of energy sources for future generations. Alternative energy sources are being sought; however no other energy source is able to provide even a fraction of energy as that of fossil fuels. Use of the alternative energy resources like wind corridors (Sindh and Baluchistan), fair use of Hydro energy (past monsoon flooding can produce enough energy that may available for next century). Uranium Resources which are enough for centuries energy production in Pakistan (Dhok Pathan Formation) lying in Siwalick series from Pliocene to Pleistocene. Among all of these, my focus is about energy from mineral fuels like Uranium from Sandstone hosted deposits in Pakistan (Siwalik Series in Pakistan). A number of uranium bearing mineralized horizons are present in the upper part of the Dhok Pathan Formation. These horizons have secondary uranium mineral carnotite and other ores. Uranium mineralization is widely distributed throughout the Siwaliks The purpose of this paper was to introduce the use of alternative energy sources in Pakistan which are present in enough amounts by nature. Pakistan is blessed with wealth of natural resources. Unfortunately, Pakistan is totally depending on non renewable energy resource. There are three main types of fossil fuels: coal, oil and natural gas. After food, fossil fuel is humanity's most important source of energy. Pakistan is among the most gas dependent economies of the world. Use of fossil fuel for energy will not only increase the demand of more fossils but it has also extreme effects on climate as well as direct and indirect effects to humans. These entire remedial thinking can only be possible if you try to use alternative energy resources rather than

  9. Leading global energy and environmental transformation: Unified ASEAN biomass-based bio-energy system incorporating the clean development mechanism

    International Nuclear Information System (INIS)

    In recent years, the ten member countries in the Association of Southeast Asia Nations (ASEAN) have experienced high economic growth and, in tandem, a substantial increment in energy usage and demand. Consequently, they are now under intense pressure to secure reliable energy supplies to keep up with their growth rate. Fossil fuels remain the primary source of energy for the ASEAN countries, due to economic and physical considerations. This situation has led to unrestrained emissions of greenhouse gases to the environment and thus effectively contributes to global climate change. The abundant supply of biomass from their tropical environmental conditions offers great potential for ASEAN countries to achieve self-reliance in energy supplies. This fact can simultaneously transform into the main driving force behind combating global climate change, which is associated with the usage of fossil fuels. This research article explores the potential and advantages for ASEAN investment in biomass-based bio-energy supply, processing and distribution network with an emphasis on regional collaborations. It also investigates the implementation and operational challenges in terms of political, economic and technical factors for the cross-border energy scheme. Reliance of ASEAN countries on the clean development mechanism (CDM) to address most of the impediments in developing the project is also under scrutiny. Unified co-operation among ASEAN countries in integrating biomass-based bio-energy systems and utilising the clean development mechanism (CDM) as the common effort could serve as the prime example for regional partnerships in achieving sustainable development for the energy and environmental sector in the future. -- Highlights: →A study that explores feasibility for ASEAN investment in biomass-based bio-energy. →Focus is given on regional supply, processing and distribution network. →Cross-border implementation and operational challenges are discussed thoroughly.

  10. Biogas : Animal Waste That Can be Alternative Energy Source

    Directory of Open Access Journals (Sweden)

    2006-09-01

    Full Text Available Biogas is a renewable energy which can be used as alternative fuel to replace fossil fuel such as oil and natural gas . Recently, diversification on the use of energy has increasingly become an important issue because the oil sources are depleting . Utilization of agricultural wastes for biogas production can minimize the consumption of commercial energy source such as kerosene as well as the use of firewood . Biogas is generated by the process of organic material digestion by certain anaerobe bacteria activity in aerobic digester . Anaerobic digestion process is basically carried out in three steps i.e. hydrolysis, acidogenic and metanogenic . Digestion process needs certain condition such as C : N ratio, temperature, acidity and also digester design . Most anaerobic digestions perform best at 32 - 35°C or at 50 - 55°C, and pH 6 .8 - 8 . At these temperatures, the digestion process essentially converts organic matter in the present of water into gaseous energy . Generally, biogas consists of methane about 60 - 70% and yield about 1,000 British Thermal Unit/ft 3 or 252 Kcal/0.028 m3 when burned . In several developing countries, as well as in Europe and the United States, biogas has been commonly used as a subtitute environmental friendly energy . Meanwhile, potentially Indonesia has abundant potential of biomass waste, however biogas has not been used maximally .

    This paper summarizes the principles and conceptual design of an integrated alternative energy system for use in typical farming communities in developing countries. A system is described that, utilizing the Sun and methane produced from crop waste, would supply sufficient electric and thermal energy to meet the basic needs of villagers for water pumping, lighting, and cooking. The system is sized to supply enough pumping capacity to irrigate 101 ha (249 acres) sufficiently to optimize annual crop yields for the community. Three economic scenarios were developed, showing net benefits to the community of $3,578 to $15,547 anually, payback periods of 9.5 to 20 years, and benefit-to-cost ratios of 1.1 to 1.9.

    In 2013, the U.S. Department of Energy (DOE) released the Revolution Now report, highlighting four transformational technologies: land-based wind power, silicon photovoltaic (PV) solar modules, light-emitting diodes (LEDs), and electric vehicles (EVs). That study and its 2014 update showed how dramatic reductions in cost are driving a surge in consumer, industrial, and commercial adoption for these clean energy technologies—as well as yearly progress. In addition to presenting the continued progress made over the last year in these areas, this year’s update goes further. Two separate sections now cover large, central, utility-scale PV plants and smaller, rooftop, distributed PV systems to highlight how both have achieved significant deployment nationwide, and have done so through different innovations, such as easier access to capital for utility-scale PV and reductions of non-hardware costs and third-party ownership for distributed PV. Along with these core technologies

  15. The convenient truth LPG: clean energy for a low carbon world

    International Nuclear Information System (INIS)

    In the context of climate change, no one solution is future-proof. It is going to take a coordinated worldwide effort to find the right mix of energy policies while balancing diverse and sometimes competing priorities. The WLPGA Climate Change Working Group (CCWG) seeks to demonstrate that the technologies needed to continue current rates of development while mitigating climate change already exist and that LP gas can be a major part of today's solutions to this challenge. LP gas is not a zero-GHG fuel. However, in most cases it can make major and immediate contributions to delivering real GHG emissions reductions. In some ways LP Gas can claim to be ahead of its time, for its clean-burning, low-carbon advantage is available at once, so that even using today's technology, most industries can exceed Kyoto GHG reduction targets by switching to LP Gas. The fact is that LP Gas produces lower GHG emissions compared to conventional energy supplies in virtually every application it is used, from stationary applications such as water heating, space heating, cooking and industrial boilers to transportation applications. There are opportunities to switch to clean burning LP gas for virtually every industry as a means meet GHG targets. LP gas is also portable, making it a perfect complement to distributed renewable energy source such as solar, wind and wave energy (and soon the fuel cell), thereby reducing our reliance centrally produced electricity. LP Gas used in combination with these renewable sources also can improve energy reliability while reducing the overall life-cycle costs. The portable and clean burning nature of LP Gas also makes it an ideal substitute for solid fuels in domestic cooking and heating applications. Household solid fuel use, overwhelmingly concentrated in developing countries, accounts for up to 30% of black carbon emissions worldwide according to some statistics. Switching to LP Gas could lower global GHG emissions as well as help to diminish

    2012-11-01

    Summit Texas Clean Energy, LLC (STCE) is developing the Texas Clean Energy Project (TCEP or the project) to be located near Penwell, Texas. The TCEP will include an Integrated Gasification Combined Cycle (IGCC) plant with a nameplate capacity of 400 megawatts electric (MWe), combined with the production of urea fertilizer and the capture, utilization and storage of carbon dioxide (CO2) sold commercially for regional use in enhanced oil recovery (EOR) in the Permian Basin of west Texas. The TCEP will utilize coal gasification technology to convert Powder River Basin subbituminous coal delivered by rail from Wyoming into a synthetic gas (syngas) which will be cleaned and further treated so that at least 90 percent of the overall carbon entering the facility will be captured. The clean syngas will then be divided into two high-hydrogen (H2) concentration streams, one of which will be combusted as a fuel in a combined cycle power block for power generation and the other converted into urea fertilizer for commercial sale. The captured CO2 will be divided into two streams: one will be used in producing the urea fertilizer and the other will be compressed for transport by pipeline for offsite use in EOR and permanent underground sequestration. The TCEP was selected by the U.S. Department of Energy (DOE) Office of Fossil Energy (FE) for cost-shared co-funded financial assistance under Round 3 of its Clean Coal Power Initiative (CCPI). A portion of this financial assistance was budgeted and provided for initial development, permitting and design activities. STCE and the DOE executed a Cooperative Agreement dated January 29, 2010, which defined the objectives of the project for all phases. During Phase 1, STCE conducted and completed all objectives defined in the initial development, permitting and design portions of the Cooperative Agreement. This topical report summarizes all work associated with the project objectives, and additional work

    Balachandran, Dave; John, Arun

    2014-04-01

    The force of adhesion of 50 nm diameter diamond-like carbon sphere probes to three quartz substrates was measured using an atomic force microscope. The force of adhesion was measured prior to cleaning, within 10 minutes after cleaning, after storage in an N2-purged cabinet, and after storage in an N2-purged vacuum oven. The evaluated cleaning recipes were SC1-like, SPM-like, and HF-based, each followed by ultra-pure deionized water (UPW) rinse and spin drying. The measurements were conducted in a Class 100 clean room at approximately 50% relative humidity. In addition, contact angle measurements were made on three additional quartz substrates using UPW before cleaning, after cleaning, and throughout N2 storage. The adhesion force increased after cleaning as compared to the pre-cleaned state, continued to increase until reaching a maximum after 5 days of N2 storage, and then decreased after 26 days for all three substrates. One substrate was then stored in a vacuum oven for 3 days, and the adhesion force decreased to 46% of the pre-cleaned state. The contact angle was reduced from over 30° before cleaning to 0° immediately after cleaning. During subsequent N2 storage, the contact angle increased to 5° or greater after 18 hours for the substrate cleaned with the HF-based recipe and after 15 days for the substrates cleaned by the SC1-like and SPM-like recipes.

  20. Evolution of competition in energy alternative pathway and the influence of energy policy on economic growth

    International Nuclear Information System (INIS)

    This work is devoted to the evolution of the competition of energy alternative pathway in China, and the influence of energy policy on economic growth by using a dynamical system method. Firstly, the relation between energy and economic growth is taken into account, and a dynamic evolution model is established. It is observed that Hopf bifurcation and chaotic behavior occurs with the varying investment in renewable energy production. Secondly, when there is no policy intervention in energy market, the evolution of competition in energy alternative pathway is also investigated. Thirdly, the system parameters are also identified by using an artificial neural network method on the basis of certain empirical statistical data in China, and the dynamics of the parameters-identified system are studied. Finally, the influences of energy policy on economic growth are empirically analyzed, and some policy recommendations are given based on the results of empirical analysis. - Highlights: • Modeling the energy economy system via the method of dynamic system. • Attaining the chaotic attractor of the energy production and economic system. • Discovering the Hopf bifurcation when the investment changes. • Proposing the alternative pathway of free competition in energy production. • Determining the turning points of parameters related to policy regulation

  1. Mesoporous Carbon-based Materials for Alternative Energy Applications

    Cross, Kimberly Michelle

    Increasing concerns for the escalating issues activated by the effect of carbon dioxide emissions on the global climate from extensive use of fossil fuels and the limited amount of fossil resources has led to an in-depth search for alternative energy systems, primarily based on nuclear or renewable energy sources. Recent innovations in the production of more efficient devices for energy harvesting, storage, and conversion are based on the incorporation of nanostructured materials into electrochemical systems. The aforementioned nano-electrochemical energy systems hold particular promise for alternative energy transportation related technologies including fuel cells, hydrogen storage, and electrochemical supercapacitors. In each of these devices, nanostructured materials can be used to increase the surface area where the critical chemical reactions occur within the same volume and mass, thereby increasing the energy density, power density, electrical efficiency, and physical robustness of the system. Durable corrosion resistant carbon support materials for fuel cells have been designed by adding conductive low cost carbon materials with chemically robust ceramic materials. Since a strict control of the pore size is mandatory to optimize properties for improved performance, chemical activation agents have been utilized as porogens to tune surface areas, pore size distributions, and composition of carbon-based mesoporous materials. Through the use of evaporative self-assembly methods, both randomly disordered and surfactant-templated, ordered carbon-silica nanocomposites have been synthesized with controlled surface area, pore volume, and pore size ranging from 50-800 m2/g, 0.025-0.75 cm3/g, and 2-10 nm, respectively. Multi-walled carbon nanotubes (MWNTs) ranging from 0.05-1.0 wt. % were added to the aforementioned carbon-silica nanocomposites, which provided an additional increase in surface area and improved conductivity. Initially, a conductivity value of 0.0667 S

  2. Economic Aspects of Air and Gas Cleaning for Nuclear Energy Processes

    International Nuclear Information System (INIS)

    In this paper the basic requirements for control of gaseous and particulate effluents are given as applied to problems of feed material production, isotope separation, fuel element fabrication, fuel recovery and reactor operation. There are also instances where non-radioactive nuclear materials with toxic or nuisance effluents such as from beryllium and zirconium production are of concern and these too must be controlled at reasonable costs. The factors involved in capital and operating costs of gas cleaning equipment and the types of applications in the United States are described in some detail. Gaseous effluent problems have, of course, been attacked and controlled by several types of device but their performance has been measured on a comparable basis. It is thus possible to judge operating characteristics on an economic basis as related to power consumption, adsorbent costs, space charges, corrosion problems and other operational factors. The United States Atomic Energy Commission through its contract with the Harvard University Air Cleaning Laboratory has initiated an evaluation program with cooperation, from the various facilities and contractors to the Commission. In this study the basic factors necessary to obtain quantitative cost delineation and evaluation have been outlined and some preliminary findings will be presented. The paper also presents a review of other economic studies made in the United States on particular process or facility applications. (author)

    This thesis presents an exploratory analysis about the institutional factors affecting the reforms of the eletricity sector in developing countries. In particular the thesis researches the process of technology selection and the factors and incentives affecting the choice between clean and unclean technologies. The co-evolutionary character of technological and institutional aspects are studied within a focus on the Costa Rican experience. Empirical evidence from the clustering process developed in Costa Rica is examined and an analytical framework is developed for a clearer understanding of the reforms that constrain the use of clean energy. The research presented here has shown the co-evolutionary character of technological and institutional selection processes, and how both influence the particular path where technology selection is defined. It has been also found that the specific institutional framework in developing countries that supports the governance mechanisms is a crucial factor when explaining technological specialisation as well as the performance of the sector, at the national level. Among the main factors within the local institutional framework, it has been found that ownership structure and market architecture as well as the governmental regulatory framework are essential elements explaining the governance structure, and to some extent, technology selection in the electricity sector. Those factors are the rules of the game by which producers define the specific technology to be implemented. (au)

    Fuel cells are an emerging technology with high potential, but also with significant market uncertainty. Fuel cells are currently in the transition from field trials to commercial introduction, and firms need to consider whether the technology fulfils the reliability and cost requirements of their current and upcoming products. This paper presented a framework to assist managers in finding the suitable valuation method for comparing different alternatives with emerging fuel cell technology. The dynamic valuation approaches of decision tree analysis, real options and system dynamics were discussed as they help in choosing the optimal timing and product structure over a long time period. Three examples of applications with fuel cells were briefly presented. The paper also addressed how the suggested valuation methods could be applied to them. These applications included maritime buoys; removable crisis management energy source container; and electrification of public transportation. It was concluded that the fuel cell technology has already become economically feasible in certain application areas. Improving technical reliability and cost reductions will make fuel cells even more competitive alternatives in new application areas. 9 refs., 1 tab., 1 fig.

    We consider general curvature-invariant modifications of the Einstein-Hilbert action that become important only in regions of extremely low space-time curvature. We investigate the late-time evolution of the universe in such models, examining the possibilities for cosmic acceleration and other ultimate destinies. The models generically possess de Sitter space as an unstable solution and exhibit an interesting set of attractor solutions which, in some cases, provide alternatives to dark energy models. We show that modifications of the form f( R) are ruled out by solar system tests of gravitation. In addition, we also review the Palatini method of variation for such theories and contrast it with the metric variation approach.

    Magain, Pierre

    2016-01-01

    Time is a parameter playing a central role in our most fundamental modelling of natural laws. Relativity theory shows that the comparison of times measured by different clocks depends on their relative motions and on the strength of the gravitational field in which they are embedded. In standard cosmology, the time parameter is the one measured by fundamental clocks, i.e. clocks at rest with respect to the expanding space. This proper time is assumed to flow at a constant rate throughout the whole history of the Universe. We make the alternative hypothesis that the rate at which cosmological time flows depends on the global geometric curvature the Universe. Using a simple one-parameter model for the relation between proper time and curvature, we build a cosmological model that fits the Type Ia Supernovae data (the best cosmological standard candles) without the need for dark energy nor probably exotic dark matter.

The dual nature of fusion energy science provides an unfolding panorama of exciting intellectual challenge and a promise of an attractive energy source for generations to come. The goal of this report is a comprehensive understanding of plasma behavior leading to an affordable and attractive fusion energy source.

  10. Dynamic overall energy balance of clean and impurity-contaminated tokamak reactors

    International Nuclear Information System (INIS)

    The energy balance of fusion reactors was investigated from the viewpoints of both physics and engineering requirements, but most of the previous investigations have been static analyses. On the other hand, dynamic behavior was studied for clean plasma. The energy balance for impurity-contaminated reactors should be investigated dynamically because impurities shorten the burning time considerably. Moreover, it is necessary to evaluate the energy balance of the whole reactor system, including engineering aspects that support plasma burning over a complete cycle. The reactor system to be analyzed should be self-consistent with regard to plasma-physics and reactor-engineering parameters, and realistic engineering limitations must be imposed. A zero-dimensional model is assumed, and the dynamic overall energy balance is investigated over a complete cycle (from the initial heating stage until the beginning of the next discharge). Simultaneous time-dependent differential equations are solved for particle density and ion and electron temperatures based on trapped particle mode losses

    Zinaman, O.; Miller, M.; Bazilian, M.

    2014-04-01

    This paper seeks to briefly characterize the evolving role of power sector regulation. Given current global dynamics, regulation of the power sector is undergoing dramatic changes. This transformation is being driven by various factors including technological advances and cost reductions in renewable energy, energy efficiency, and demand management; increasing air pollution and climate change concerns; and persistent pressure for ensuring sustainable economic development and increased access to energy services by the poor. These issues add to the already complex task of power sector regulation, of which the fundamental remit remains to objectively and transparently ensure least-cost service delivery at high quality. While no single regulatory task is trivial to undertake, it is the prioritization and harmonization of a multitude of objectives that exemplifies the essential challenge of power sector regulation. Evolving regulatory roles can be understood through the concept of existing objectives and an additional layer of emerging objectives. Following this categorization, we describe seven existing objectives of power sector regulators and nine emerging objectives, highlighting key challenges and outlining interdependencies. This essay serves as a preliminary installment in the Clean Energy Regulatory Initiative (CERI) series, and aims to lay the groundwork for subsequent reports and case studies that will explore these topics in more depth.

    2007-04-01

    Two series of ordered mesoporous materials, SBA-15 silica and CMK-3 carbon were synthesized. The ordered nanostructure of these materials was confirmed by TEM and XRD analysis. Structural parameters including the specific surface area, pore volume and pore size distribution were determined on the basis of nitrogen adsorption data at 77 K. Potential applications of these materials were explored in relation to the CO 2 sequestering, methane storage and fuel desulfurization. Initial studies of both materials showed their usefulness for environmental and clean energy applications. SBA-15 modified with triethanolamine showed a very good adsorption selectivity for CO 2 while its adsorption reversibility was retained. Also, this material after CuCl deposition was useful for removal of fuel thiophenes. However, CMK-3 was shown to be promising material for storage of natural gas. As high as 41 wt.% of methane was stored in this material in the presence of appropriate amount of water.

    This analysis identifies candidate locations, in a broad sense, where there are high concentrations of federal government agency use of electricity, which are also suitable areas for near-term SMRs. Near-term SMRs are based on light-water reactor (LWR) technology with compact design features that are expected to offer a host of safety, siting, construction, and economic benefits. These smaller plants are ideally suited for small electric grids and for locations that cannot support large reactors, thus providing utilities or governement entities with the flexibility to scale power production as demand changes by adding additional power by deploying more modules or reactors in phases. This research project is aimed at providing methodologies, information, and insights to assist the federal government in meeting federal clean energy goals.

  16. Health and economic costs of alternative energy sources

    International Nuclear Information System (INIS)

    National energy policy requires realistic totalling of costs in assessing energy alternatives. The Biomedical and Environmental Assessment Division (BEAD) at Brookhaven is estimating health and environmental costs of energy production and use. It was estimated that the production of electric power from all sources in the USA in 1975 was associated with 2000-19,000 deaths and 29,000-48,000 disabilities; this is roughly 0.2-2% of total deaths in the USA for ages 1-74. The estimated health effects associated with a total fuel cycle standardized to produce 1010kWh electric power were: from coal, estimated deaths 10-200, estimated disabilities 300-500; from oil, estimated deaths 3-150, estimated disabilities 150-300; from gas, estimated deaths 0.2, estimated disabilities 20; from nuclear power, estimated deaths 1-3, estimated disabilities 8-30. The differences in the year 2000 between health impacts of the US energy system under normal growth expectations and under conditions of a nuclear moratorium were estimated. On the assumption that the nuclear moratorium would require 200 additional 1000-MW(e) coal-fired power plants and that, with improved control technology, sulphur emissions were equivalent to 0.5% sulphur coal (12,500Btu/lb), additional estimated deaths were 1500-18,000 annually. By the same assumptions, it turns out that a nationwide nuclear moratorium could lead to low economic losses initially that would rise rapidly after the year 2000, so that the cost to the USA in 2010 would be US $109x109. Summing the costs for 1975 through 2050, the present value of these losses would be US $77x109 or US $595x109, depending on whether public decisions are to be based on a 10% or 5% discount rate.

  19. Credits/exemptions for clean energy exports in the context of a Canadian GHG strategy

    International Nuclear Information System (INIS)

    Greenhouse gas emissions is a global issue because the effect of a tonne of carbon dioxide emissions is independent of where it occurs, or during which stage or production, distribution and final use of a given product. International trade complicates the relationship between the final use of goods and where the emissions associated with their production and distribution occur. Besides the large bilateral trade with the US in automobiles and parts, Canada's exports lean largely toward energy intensive commodities such as oil, gas, chemicals, steel, pulp and paper, and aluminum. In consequence, there is a high volume of greenhouse gas emissions in Canada associated with goods produced for consumption elsewhere. Under the Kyoto Protocol, this growing export of energy intensive goods, creates a greenhouse gas inventory burden for Canadians. The author noted that the Kyoto Protocol greenhouse gas accounting system attributes upstream emissions to the exporter. It was argued that since Canada's natural gas exports to the United States reduce their coal consumption for electricity generation and fuel oil for industrial boilers, Canada should have its greenhouse gas inventory adjusted through either a credit for clean energy exports or through exemption of upstream emissions. 7 figs

  20. Alternative concept for a fast energy amplifier accelerator driven reactor

    International Nuclear Information System (INIS)

    Recently Rubbia et al. introduced a conceptual design of a Fast Energy Amplifier (EA) as an advanced innovative reactor which utilizes a neutron spallation source induced by protons as an external source in a subcritical array imbibed a molten lead coolant which, besides being breeder and waste burner, generates energy. This paper introduces some qualitative changes in Rubbia's concept such as more than one point of spallation, in order to reduce the requirement in the energy and current of the accelerator, and mainly to make a more flat neutron distribution. The subcritical core which in Rubbia's concept is an hexagonal array of pins immersed in a molten lead coolant is replaced by a concept of a solid lead calandria with the fuel elements in channels cooled by helium, allowing on line refueling or shuffling, and the utilization of a direct thermodynamic cycle (Brayton), which is more efficient than a vapor cycle. Although the calculations to demonstrate the feasibility of the EA alternative concept are underway and not yet finished, these ideas do not violate the basic physics of the EA, as showed in this paper, with evident advantages in the fuel cycle (on line refueling); reduced requirements in the accelerator complex, which is more realistic and economical in today accelerators technology; and finally the utilization of He as coolant compared with molten Pb is more close to the proved technology given the know how of gas cooled reactors and more efficient from the thermodynamic point of view, allowing simplification and the utilization in other process, besides electricity generation, as hydrogen generation.
