Republic Serbia has produced and consumed natural gas domestically since 1952, but has always been net importer. Strategy of Energy Development in Serbia and, especially, National Action Plan for the Gasification on the Territory of Republic of Serbia dedicated special attention to gas economy development in respect with expected contribution in efficient energy use and environmental policy protection in our country. Option of expanded share of natural gas in fulfilling energy requirements in future is reasonable, considering natural gas with its energetic, ecological and economical characteristics as very suitable fuel. Also, in mid-term and most probably in long-term period, the gas import is expected to be more advantageous than oil import. The paper deals the basic features of natural gas consumption in Serbia in nineties and analyses the further development in gas sector for next period until 2015 based on strategic analyses. (auth)

Liquefied natural gas : a Canadian perspective : an energy market assessment

International Nuclear Information System (INIS)

2009-01-01

World requirements for energy and natural gas are expected to increase in the near future. This energy market assessment presented an overview of global liquefied natural gas (LNG) supply and demand, and discussed the potential effects that imported LNG may have on Canadian gas markets and energy infrastructure. Regasification projects will double the world's existing LNG receiving capacity by 2015. However, LNG pricing will still be indexed to the price of crude oil and oil products in the future. LNG price differences will affect trading opportunities as well as the flow of LNG between regions. North American LNG facility development will be influenced by outlooks for continental gas supply and demand. Current declines combined with recent increases in United States natural gas production from unconventional gas resources will reduce requirements for LNG in the near future, and may have a significant impact on long-term North American and global LNG requirements. Canada's existing facilities are located competitively with other terminals. 33 figs.

Renewable energy as a natural gas price hedge: the case of wind

International Nuclear Information System (INIS)

Berry, David

2005-01-01

Electric utilities use natural gas to fuel many of their power plants, especially those plants which provide electricity at peak and intermediate hours. Natural gas prices are highly volatile and have shown a general upward trend. Wind energy can provide a cost-effective hedge against natural gas price volatility or price increases. This conclusion is based on analysis of the costs of marginal conventional generation given the historical probability distribution of natural gas prices, the cost of wind energy, wind integration costs, transmission costs for wind energy, the capacity value of wind, and environmental benefits of wind energy for a hypothetical utility in the Southwestern United States. The efficacy of using wind energy as a hedge at a particular utility will depend on site specific conditions

In this paper, the greenhouse gas and energy balances of the production and use for space heating of substitute natural gas from biomass (bio-SNG) for space heat are analysed. These balances are compared to the use of natural gas and solid biomass as wood chips to provide the same service. The reduction of the greenhouse gas emissions (CO{sub 2}-eq.) - carbon dioxide, methane and nitrous oxide - and of the fossil primary energy use is investigated in a life cycle assessment (LCA). This assessment was performed for nine systems for bio-SNG; three types of gasification technologies (O{sub 2}-blown entrained flow, O{sub 2}-blown circulating fluidised bed and air-steam indirect gasification) with three different types of feedstock (forest residues, miscanthus and short rotation forestry). The greenhouse gas analysis shows that forest residues using the air-steam indirect gasification technology result in the lowest greenhouse gas emissions (in CO{sub 2}-eq. 32 kg MWh{sup -1} of heat output). This combination results in 80% reduction of greenhouse gas emissions when compared to natural gas and a 29% reduction of greenhouse gases if the forest residues were converted to wood chips and combusted. The gasification technologies O{sub 2}-blown entrained flow and O{sub 2}-blown circulating fluidised bed gasification have higher greenhouse gas emissions that range between in CO{sub 2}-eq. 41 to 75 kg MWh{sup -1} of heat output depending on the feedstock. When comparing feedstocks in the bio-SNG systems, miscanthus had the highest greenhouse gas emissions bio-SNG systems producing in CO2-eq. 57-75 kg MWh{sup -1} of heat output. Energy analysis shows that the total primary energy use is higher for bio-SNG systems (1.59-2.13 MWh MWh{sup -1} of heat output) than for the reference systems (in 1.37-1.51 MWh MWh{sup -1} of heat output). However, with bio-SNG the fossil primary energy consumption is reduced compared to natural gas. For example, fossil primary energy use is reduced by

2000-01-01

Natural gas with its abundant reserves, largely distributed all around the world, and with its low environmental impacts, should assert its position since the beginning of the 21. century. However, the fundamentals of our world are changing more and more rapidly and some short term events can modify this long term optimistic vision of natural gas development. This was the topic debated during a round table of the WOC 9 working committee of the CMG 2000 worldwide gas congress: the long term future of natural gas industry, the population need for a sustainable development, the potentialities of gas resources, the need for large scale interconnected energy networks, the new technologies favourable to the development of natural gas uses, the progressive 'decarbonization' of energy sources, the global warming and the role of R and D, the risks that could threat natural gas development.

US Department of Energy investments in natural gas R ampersand D: An analysis of the gas industry proposal

International Nuclear Information System (INIS)

Sutherland, R.J.

1992-01-01

The natural gas industry has proposed an increase in the DOE gas R ampersand D budget from about $100 million to about $250 million per year for each of the next 10 years. The proposal includes four programs: natural gas supplies, fuel cells, natural gas vehicles and stationary combustion systems. This paper is a qualitative assessment of the gas industry proposal and recommends a natural gas R ampersand D strategy for the DOE. The methodology is a conceptual framework based on an analysis of market failures and the energy policy objectives of the DOE's (1991) National Energy Strategy. This framework would assist the DOE in constructing an R ampersand D portfolio that achieves energy policy objectives. The natural gas supply program is recommended to the extent that it contributes to energy price stability. Stationary combustion programs are supported on grounds of economic efficiency and environmental quality. The fuel cell program is supported on grounds of environmental quality. The natural gas vehicle program may potentially contribute to environmental quality and energy price stability. The R ampersand D programs in natural gas vehicles and in fuel cells should be complemented with policies that encourage the commercialization and use of the technology, not merely its development

The article analyses Russia's Eastern energy strategy in the sectors of oil and natural gas, presenting its main aspects and examining it from the security perspective against the backdrop of official Russian documents. The goals set by the strategy are compared with the steps presently taken and planned by the Russian administration, as well as with short- and medium-term Russian energy policies in the sectors of oil and natural gas. The authors conclude that implementation of the Energy Strategy to 2030 in the sectors of oil and natural gas will be highly complicated in the Eastern vector of Russian politics and achievable only if new deposits are found. - Highlights: ► We compare goals of the Russia's Eastern energy strategy in the sectors of oil and natural gas with real policy.► In the Eastern vector are included China, both Korean states and Japan. ► For Russia's energy strategy to 2030 the Eastern market in the sector of oil and natural gas is advantageous and desirable. ► The present conditions can bring economic as well as political risks.

Natural gas to improve energy security in Small Island Developing States: A techno-economic analysis

Directory of Open Access Journals (Sweden)

Pravesh Raghoo

Full Text Available There is a paucity of studies on natural gas-based energy production in Small Island Developing States (SIDS even though technological improvements today are likely to make the application of natural gas more and more feasible. The development of natural gas in some of the regions of the Pacific, Africa, Indian Ocean and Caribbean attracts nearby countries and the coming up of the compressed natural gas (CNG technology which can serve regional markets are two motivations for SIDS to develop natural gas-based energy provision. A third factor concerns long-term energy security. Due to continued reliance on fossil fuels and slow uptake of renewable energy, there is a need to diversify SIDS’ energy mix for a sustainable electricity industry. Comparing the opportunities and constraints of liquefied natural gas (LNG and compressed natural gas (CNG in a SIDS-specific context, this paper discusses how to improve the integration of natural gas in prevailing energy regimes in SIDS as an alternative fuel to oil and complementary to renewable energy sources. To illustrate feasibility in practice, a techno-economic analysis is carried out using the island of Mauritius as an example. Keywords: Energy security, Natural gas, Small Island Developing States

1967-08-01

This report on the natural gas industry of Canada includes: composition and uses of natural gas, production statistics, exploration and development, reserve estimates, natural gas processing, transportation, and marketing. For the Canadian natural gas industry, 1966 was a year of moderate expansion in all phases, with a strong demand continuing for sulfur and liquid hydrocarbons produced as by-products of gas processing. Value of natural gas production increased to $199 million and ranked sixth in terms of value of mineral ouput in Canada. Currently, natural gas provides over 70% of Canada's energy requirements. Proved remaining marketable reserves are estimated to be in excess of a 29-yr supply.

Natural gas prices in the Maritimes : an energy market assessment

International Nuclear Information System (INIS)

2004-03-01

The National Energy Board monitors the supply and price of natural gas in the Maritimes. This report contains the results and analysis of a survey of the wholesale natural gas prices paid by Canadian buyers in the Maritimes from November 2002 to October 2003. The objective of the report is to improve the understanding of the market factors that influence wholesale natural gas prices in the Maritimes. A comparative evaluation of domestic and export prices shows that Canadian buyers have had access to gas at prices similar to the export market at St. Stephen, New Brunswick. Since the number of participants in the domestic market is low, only four large buyers have a major impact on average prices in the region. The challenge for small buyers will be to buy gas from others who can divert some of their own sales of use. However, these sellers may not want to over-commit to new firm sales in case they have to re-purchase the gas during shortages that may occur due to fluctuations in production or shipping. It was noted that a new gas supply into the region would support many buyers and sellers, and could lead to a more transparent Maritime natural gas market. The National Energy Board is satisfied that the Maritime natural gas market is currently performing as well as can be expected, given its young stage of development. 1 tab., 8 figs., 1 appendix

Is inexpensive natural gas hindering the grid energy storage industry?

International Nuclear Information System (INIS)

Hittinger, Eric; Lueken, Roger

2015-01-01

Grid energy storage is a maturing technology and forecasts of the industry's growth have been promising. However, recent years have realized little growth in actual deployments of grid-level storage and several high-profile storage companies and projects have failed. We hypothesize that falling natural gas prices have significantly reduced the potential profit from many U.S. energy storage projects since 2009 and quantify that effect. We use engineering–economic models to calculate the monthly revenue to energy storage devices providing frequency regulation and energy arbitrage in several electricity markets and compare that revenue to prevailing natural gas prices. We find that flywheel devices providing frequency regulation were profitable in months when natural gas prices were above $7/mcf, but face difficulties at current prices (around $4/mcf). For energy arbitrage alone, we find that the breakeven capital cost for large-scale storage was around $300/kWh in several key locations in 2004–2008, but is around $100/kWh in the same locations today. Though cost and performance improvements have been continually decreasing the effective cost of energy services from storage, fundamental market signals indicating the need for energy storage are at or near 10-year lows for both energy arbitrage and frequency regulation. - Highlights: • We use engineering–economic models to determine breakeven capital cost of storage. • Two applications are examined: frequency regulation and energy arbitrage. • For both services, potential revenue has decreased significantly since 2008. • We show a high correlation of revenue with natural gas price. • We demonstrate a causal relationship using the PHORUM grid modeling software.

Natural gas for power generation : issues and implications : an energy market assessment

International Nuclear Information System (INIS)

2006-06-01

This report presented a historical examination of trends in natural gas-fired generation as well as a perspective on the issues and potential implications of increasing reliance on natural gas. Potential changes to Canadian energy consumers were reviewed in addition to natural gas infrastructure and services. Electricity prices relating to natural gas generation were examined. A broad regional and continental perspective was employed to account for energy market integration and the fact that gas trends reflect developments outside of Canada. The report was divided into 2 sections: (1) an examination of the trend toward natural-gas fired generation of electricity in North America; and (2) an examination of issues in closer detail from a regional perspective followed by a discussion of the changes in generation and natural gas markets in western, eastern, and central North America. Questions arising from the analysis of specific regional supply, demand and infrastructure situations were also examined. Recommendations were presented for issues concerning the current gas market and the appropriate role of the government in ensuring adequate generation. Uncertainties in future natural gas supply were also considered. It was concluded that rapid industrial growth will continue to increase demand for natural gas and electricity supply. 5 figs

Can deployment of renewable energy put downward pressure on natural gas prices?

International Nuclear Information System (INIS)

Wiser, Ryan; Bolinger, Mark

2007-01-01

High and volatile natural gas prices have increasingly led to calls for investments in renewable energy. One line of argument is that deployment of these resources may lead to reductions in the demand for and price of natural gas. Many recent US-based modeling studies have demonstrated that this effect could provide significant consumer savings. In this article we evaluate these studies, and benchmark their findings against economic theory, other modeling results, and a limited empirical literature. We find that many uncertainties remain regarding the absolute magnitude of this effect, and that the reduction in natural gas prices may not represent an increase in aggregate economic wealth. Nonetheless, we conclude that many of the studies of the impact of renewable energy on natural gas prices appear to have represented this effect within reason, given current knowledge. These studies specifically suggest that a 1% reduction in US natural gas demand could lead to long-term average wellhead price reductions of 0.8-2%, and that each megawatt-hour of renewable energy may benefit natural gas consumers to the tune of at least $7.5-20

Natural gas cost for evaluating energy resource opportunities at Fort Stewart

Energy Technology Data Exchange (ETDEWEB)

Stucky, D.J.; Shankle, S.A.

1993-01-01

Ft. Stewart, a United States Army Forces Command (FORSCOM) installation located near Hinesville, Georgia, is currently undergoing an evaluation of its energy usage, which is being performed by Pacific Northwest Laboratory. In order to examine the energy resource opportunities (EROs) at Ft. Stewart, marginal fuel costs must be calculated. The marginal, or avoided, cost of gas service is used in conjunction with the estimated energy savings of an ERO to calculate the dollar value of those savings. In the case of natural gas, the costing becomes more complicated due to the installation of a propane-air mixing station. The propane-air station is being built under a shared energy savings (SES) contract. The building of a propane-air station allows Ft. Stewart to purchase natural gas from their local utility at an interruptible rate, which is lower than the rate for contracting natural gas on a firm basis. The propane-air station will also provide Ft. Stewart with fuel in the event that the natural gas supply is curtailed. While the propane-air station does not affect the actual cost of natural gas, it does affect the cost of services provided by gas. Because the propane-air station and the SES contract affect the cost of gas service, they must be included in the analysis. Our analysis indicates a marginal cost of gas service of 30.0 cents per therm, assuming a total propane usage by the mixing station of 42,278 gallons (38,600 therms) annually. Because the amount of propane that may be required in the event of a curtailment is small relative to the total service requirement, variations in the actual amount should not significantly affect the cost per therm.

2013-01-01

Abstract: CFD (Computational fluid dynamics) is used to evaluate the thermodynamic second-law effects of thermal radiation in turbulent diffusion natural gas flames. Radiative heat transfer processes in gas and at solid walls are identified as important causes of energy devaluation in the combusting flows. The thermodynamic role of thermal radiation cannot be neglected when compared to that of heat conduction and convection, mass diffusion, chemical reactions, and viscous dissipation. An energy devaluation number is also defined, with which the optimum fuel–air equivalence for combusting flows can be determined. The optimum fuel–air equivalence ratio for a natural gas flame is determined to be 0.7. The CFD model is validated against experimental measurements. - Highlights: • Thermodynamic effects of thermal radiation in combusting flows analyzed. • General equation for second-law analyses of combusting flows extended. • Optimum fuel–air equivalence ratio determined for natural gas flame

Quantifying the value that energy efficiency and renewable energy provide as a hedge against volatile natural gas prices

Bolinger, Mark; Wiser, Ryan; Bachrach, Devra; Golove, William

Advocates of energy efficiency and renewable energy have long argued that such technologies can mitigate fuel price risk within a resource portfolio. Such arguments--made with renewed vigor in the wake of unprecedented natural gas price volatility during the winter of 2000/2001--have mostly been qualitative in nature, however, with few attempts to actually quantify the price stability benefit that these sources provide. In evaluating this benefit, it is important to recognize that alternative price hedging instruments are available--in particular, gas-based financial derivatives (futures and swaps) and physical, fixed-price gas contracts. Whether energy efficiency and renewable energy can provide price stability at lower cost than these alternative means is therefore a key question for resource acquisition planners. In this paper we evaluate the cost of hedging gas price risk through financial hedging instruments. To do this, we compare the price of a 10-year natural gas swap (i.e., what it costs to lock in prices over the next 10 years) to a 10-year natural gas price forecast (i.e., what the market is expecting spot natural gas prices to be over the next 10 years). We find that over the past two years natural gas users have had to pay a premium as high as $0.76/mmBtu (0.53/242/kWh at an aggressive 7,000 Btu/kWh heat rate) over expected spot prices to lock in natural gas prices for the next 10 years. This incremental cost to hedge gas price risk exposure is potentially large enough - particularly if incorporated by policymakers and regulators into decision-making practices - to tip the scales away from new investments in variable-price, natural gas-fired generation and in favor of fixed-price investments in energy efficiency and renewable energy.

This paper surveyed the natural gas distribution systems employed in the Italian civil, industrial and thermoelectric sectors to identify those installations which can make use of gas decompression energy recovery systems (consisting of turbo-expanders or alternative expanders) to economically generate electric power. Estimates were then made of the total amount of potential energy savings. The study considered as eligible for energy savings interventions only those plants with a greater than 5,000 standard cubic meter per hour plant capacity. It was evaluated that, with suitable decompression equipment installed at 50 key installations (33 civil, 15 industrial), about 200 GWh of power could be produced annually, representing potential savings of about 22,000 petroleum equivalent tonnes of energy. A comparative analysis was done on three investment alternatives involving inputs of varying amounts of Government financial assistance

Canada's conventional natural gas resources : a status report : an energy market assessment

International Nuclear Information System (INIS)

2004-04-01

The National Energy Board monitors the supply of all energy commodities in Canada as well as the demand for Canadian energy commodities in domestic and export markets. Energy market assessment reports examine different facets of the Canadian energy market and include long term-assessments of Canada's supply and demand as well as near-term energy market issues. This report examines the geological potential for conventional natural gas resources. An estimate of those resources for Canada was also presented. The main objective of the report is to set the groundwork for future partnerships between provincial, territorial and federal agencies. The size of Alberta's conventional natural gas resources is being examined in partnership with the Alberta Energy and Utilities Board (EUB). The ultimate potential for conventional natural gas in British Columbia is being assessed by the British Columbia Ministry of Energy and Mines. The Board's internal assessment for 2004 has revealed an estimate of 207 trillion cubic feet for the ultimate of conventional natural gas in Alberta. This estimate is higher than the estimate provided by the Canadian Gas Potential Committee in 2001 and higher than the 1992 assessment of the EUB. It was noted that most undiscovered resources in Alberta will be found in the shallow Cretaceous zones, not in deep Devonian zones. The Board also revised its estimate for the Mackenzie Delta-Beaufort Sea region and the East Newfoundland Basin. The current estimate for ultimate potential of conventional natural gas in Canada is 501 trillion cubic feet, with the following distribution of the resources by basin: Western Canada Sedimentary Basin (54.5 per cent), Northern Canada (23.1 per cent), East Coast (18.3 per cent), West Coast (3.4 per cent), Ontario (0.5 per cent), and Gulf of St. Lawrence (0.3 per cent). 39 refs., 7 tabs., 13 figs

North American natural gas liquids pricing and convergence : an energy market assessment

International Nuclear Information System (INIS)

2001-05-01

A background on natural gas liquids (NGL) pricing was presented along with a discussion regarding the impact of energy price convergence. The high energy prices in the fall of 2000 were a result of many factors, including the high price of NGLs. All NGL components such as ethane, propane and butane can be used as petrochemical feedstock. In the winter of 2000/2001 the relationship between liquids and crude oil prices collapsed when high energy prices led to a situation where, for a short while, extraction of liquids from natural gas became uneconomic since producers got more value for NGLs left in the gas stream. As a result, when the supply and demand balances for NGL tightened in many regions of North America, NGL prices were reflecting the unprecedented high natural gas prices. This paper also explained how the four major North American NGL trading hubs in Alberta, Ontario, Kansas and Texas operate. The pricing events of 2000 have impacted on the NGL industry and energy prices remain an issue since both crude oil and natural gas price are forecasted to remain strong in the near future. 5 figs

Natural gas and renewable energy each contribute to economic growth, energy independence, and carbon mitigation, sometimes independently and sometimes collectively. Often, natural gas and renewables are considered competitors in markets, such as those for bulk electricity. This paper attempts to address the question, 'Given near- and long-term needs for abundant, cleaner energy sources and decarbonization, how can more compelling business models be created so that these two domestic forms of energy work in greater concert?' This paper explores revenue opportunities that emerge from systems-level perspectives in 'bulk energy' (large-scale electricity and natural gas production, transmission, and trade) and four 'distribution edge' subsectors: industrial, residential, commercial, and transportation end uses.

Growing natural gas usage

International Nuclear Information System (INIS)

Saarni, T.

1996-01-01

Finnish natural gas usage topped the 3.3 billion cubic metre mark last year, up 3.6 % on the 1994 figure. Growth has increased now for 12 years in a row. Thanks to offtake by large individual users, the pipeline network has been expanded from South-East Finland to the Greater Helsinki area and central southern Finland. Natural gas plays a much larger role in this region than the 10 % accounted for by natural gas nationally would indicate. The growth in the share of Finland's energy use accounted for by natural gas has served to broaden the country's energy supply base. Natural gas has replaced coal and oil, which has considerably reduced the level of emissions resulting form energy generation

It focuses on identifying factors that affect natural gas prices and describe the current functioning of domestic regional markets in British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, Quebec and in the Atlantic provinces.The report emphasizes the growth in demand for natural gas throughout North America, and the aggressive response by producers to the current high price environment with increased drilling programs. The report also predicts a supply and demand adjustment over time, and an accompanying relief in natural gas prices, although the Board is not able to predict with certainty any movements in commodity markets. The Board's findings indicate that domestic users of natural gas paid less than export customers until 1998, at which point the two prices have converged. The end result of the convergence was that Canadians have had access to natural gas under terms and conditions which were no less favourable than those in effect for export customers. The influence of electronic trading systems is reviewed, noting that spot markets and futures markets such as the NYMEX and AECO-C/NIT have had a significant impact on the pricing of natural gas, mostly by allowing market participants to manage price volatility by forward contracting. 1 tab., 42 figs., 1 glossary

The British Columbia natural gas market overview and assessment : an energy market assessment

International Nuclear Information System (INIS)

2004-04-01

The National Energy Board monitors the supply of all energy commodities in Canada along with the demand for Canadian energy commodities in domestic and export markets. This report provides an assessment of the natural gas market in British Columbia (BC) and discusses several issues facing the market. The main challenges facing the market in recent years have been rising prices, price spikes and increased price volatility. New exploration and development projects have been announced along with new gas pipeline projects that move gas to eastern markets. Industrial consumers are exploring fuel alternatives to reduce natural gas consumption. Despite these challenges, the Board believes the natural gas market in British Columbia is working well. Natural gas prices are integrated with the North American market, consumers have responded to higher prices by reducing demand, and producers have increased exploration and production. Price discovery has improved due to better pricing reporting standards and access to electronic gas trading at pricing points for BC gas. The small market size in British Columbia and the lack of storage in the Lower Mainland limit market liquidity in comparison with other major market centres. 20 figs

Natural gas pricing

Natural gas pricing is the heart and soul of the gas business. Price specifically affects every phase of the industry. Too low a price will result in short supplies as seen in the mid-1970s when natural gas was scarce and in tight supply. To fully understand the pricing of this energy commodity, it is important to understand the total energy picture. In addition, the effect and impact of world and US economies, and economics in general are crucial to understanding natural gas pricing. The purpose of this presentation will be to show the parameters going into US natural gas pricing including the influence of the many outside industry factors like crude oil and coal pricing, market drivers pushing the gas industry, supply/demand parameters, risk management for buyers and sellers, and other elements involved in pricing analysis

Energy Security prospects in Cyprus and Israel: A focus on Natural Gas

Directory of Open Access Journals (Sweden)

Constantinos Taliotis

2014-06-01

Full Text Available The global production of natural gas has increased from 1226 bcm in 1973 to 3282 bcm in 2010 and is projected to continue rising by an annual growth rate of 1.6% between 2010 to 2035. Cyprus and Israel have recently made major offshore discoveries of natural gas, which can supply to a great extent the two countries’ current domestic energy needs for the next few decades and still export a substantial volume. MESSAGE, a global optimization model was used to explore the possible interactions between the two countries’ energy systems. Scenarios are presented that assess the export potential for electricity (generated by gas-fired power plants, liquefied natural gas (LNG or gas-to-liquid products (GTL. The results are compared to a scenario without any available reserves to illustrate the financial benefits that will arise from the exploitation of the gas resources in the two countries.

The natural gas industry in the Czech Republic is one of the oldest in Europe. In the past, natural gas has played a modest role in the Czech energy supply: coal and town gas from coal and lignite were the major energy sources. However, more and more use is made of natural gas, imported from Russia (Gazprom) and Norway. Besides, the Czech natural gas distribution, transportation and storage system occupies a key position in the Central-European natural gas network

Natural gas transmission and distribution model of the National Energy Modeling System

International Nuclear Information System (INIS)

1997-02-01

The Natural Gas Transmission and Distribution Model (NGTDM) is the component of the National Energy Modeling System (NEMS) that is used to represent the domestic natural gas transmission and distribution system. NEMS was developed in the Office of Integrated Analysis and Forecasting of the Energy Information Administration (EIA). NEMS is the third in a series of computer-based, midterm energy modeling systems used since 1974 by the EIA and its predecessor, the Federal Energy Administration, to analyze domestic energy-economy markets and develop projections. From 1982 through 1993, the Intermediate Future Forecasting System (IFFS) was used by the EIA for its analyses, and the Gas Analysis Modeling System (GAMS) was used within IFFS to represent natural gas markets. Prior to 1982, the Midterm Energy Forecasting System (MEFS), also referred to as the Project Independence Evaluation System (PIES), was employed. NEMS was developed to enhance and update EIA's modeling capability by internally incorporating models of energy markets that had previously been analyzed off-line. In addition, greater structural detail in NEMS permits the analysis of a broader range of energy issues. The time horizon of NEMS is the midterm period (i.e., through 2015). In order to represent the regional differences in energy markets, the component models of NEMS function at regional levels appropriate for the markets represented, with subsequent aggregation/disaggregation to the Census Division level for reporting purposes

Domestic natural gas production was largely stagnant from the mid-1970s until about 2005. However, beginning in the late 1990s, advances linking horizontal drilling techniques with hydraulic fracturing allowed drilling to proceed in shale and other formations at much lower cost. The result was a slow, steady increase in unconventional gas production. The Joint Institute for Strategic Energy Analysis (JISEA) designed this study to address four related key questions, which are a subset from the wider dialogue on natural gas; regarding the life cycle greenhouse gas (GHG) emissions associated with shale gas compared to conventional natural gas and other fuels used to generate electricity; existing legal and regulatory frameworks governing unconventional gas development at federal, state, and local levels, and changes in response to the rapid industry growth and public concerns; natural gas production companies changing their water-related practices; and demand for natural gas in the electric sector.

Yoon, Sekwang; Binns, Michael; Park, Sangmin; Kim, Jin-Kuk

2017-01-01

A new NGL (natural gas liquids) recovery process configuration is proposed which can offer improved energy efficiency and hydrocarbon recovery. The new process configuration is an evolution of the conventional turboexpander processes with the introduction of a split stream transferring part of the feed to the demethanizer column. In this way additional heat recovery is possible which improves the energy efficiency of the process. To evaluate the new process configuration a number of different NGL recovery process configurations are optimized and compared using a process simulator linked interactively with external optimization methods. Process integration methodology is applied as part of the optimization to improve energy recovery during the optimization. Analysis of the new process configuration compared with conventional turbo-expander process designs demonstrates the benefits of the new process configuration. - Highlights: • Development of a new energy-efficient natural gas liquids recovery process. • Improving energy recovery with application of process integration techniques. • Considering multiple different structural changes lead to considerable energy savings.

Natural gas vehicles in Italy

Mariani, F.

1991-01-01

The technology of compressed natural gas (CNG) for road vehicles originated 50 years ago in Italy, always able to adapt itself to changes in energy supply and demand situations and national assets. Now, due to the public's growing concern for air pollution abatement and recent national energy policies calling for energy diversification, the commercialization of natural gas road vehicles is receiving new momentum. However, proper fuel taxation and an increased number of natural gas distribution stations are required to support this growing market potential. Operators of urban bus fleets stand to gain substantially from conversion to natural gas automotive fuels due to natural gas being a relatively cheap, clean alternative

Communication on climate, energy, natural gas and forests as a problem for energy planning

DEFF Research Database (Denmark)

Czeskleba-Dupont, Rolf

Danish energy planning has since its inception in the end of the 1970s been politically controversial, which led to language problems of communicating on alternatives (natural gas, nuclear energy). But previously alternative scenarios were in the 1990s successfully transformed into law...... that it can happen on the ground of wrong premises (on CO2 neutrality e.g.) that a shift say from natural gas to wood combustion can be interpreted as a solution to climate problems, whereas this in reality aggravates them. Not the least because forests because of continuously high emissions of CO2...

The Energy Regulatory Commission. The Regulation of Natural Gas in Mexico

International Nuclear Information System (INIS)

1995-01-01

In May of 1995 the Congress approved amendments to the Regulatory Law of Constitutional article 27 on Petroleum. This legal reform fundamentally redefined the petroleum industry and authorizes the private sector to construct, operate, and own natural gas transportation, storage and distribution systems-activities previously reserved to the state. To complement these reforms and to implement the legislative mandate of the Regulatory Law on Petroleum, the Natural Gas Regulation (Reglamento de Gas Natural) was issued in November 1995. The regulation reconciles the interests of the various natural gas industry participants and signifies a Federal Commitment to promote comprehensive development of the industry. In parallel with the development of the substantive legal framework, the law of the Comision Reguladora de Energia (CRE) was also enacted by Congress in October 1995 to strength the institutional framework and implemented the legal changes. This law defines the CRE as an agency of the Energy Ministry with technical, operational, and budgetary autonomy, and responsibility for implementing natural gas industry regulation. (Author)

1998-01-01

The steam and gas turbine power plant for combine heat (for district heating of Skopje - the capital of Macedonia) and power (connected to the grid) production is analyzed and determined. Two variants of power plants are analyzed: power plant with gas turbine, heat recovery steam generator and a back pressure steam turbine; and power plant with two gas turbines, two heat recovery steam generators (HRSG) and one back pressure steam turbine. The power plant would operate on natural gas as the main fuel source. It will be burnt in the gas turbine as well in the HRSG as an auxiliary fuel.The backup fuel for the gas turbine would be light oil. In normal operation, the HRSG uses the waste heat of the exhaust gases from the gas turbine. During gas turbine shutdowns, the HRSG can continue to generate the maximum steam capacity. The heat for district heating would be produce in HRSG by flue gases from the gas turbine and in the heat exchanger by condensed steam from back pressure turbine. The main parameters of the combined power plant, as: overall energy efficiency, natural gas consumption, natural gas saving are analyzed and determined in comparison with separated production of heat (for district heating) and power (for electrical grid).

2010-09-15

Increasing population and economic growth in developing countries has changed their energy consumption patterns. So, the conventional systems of energy supply have become inadequate to deal with rising energy demand. Iran has great reservoirs of natural gas and its natural gas usage is far more than average international standard. Dominance of natural gas share in energy basket in Iran, make it necessary to consider energy efficient technologies and solutions for this domain. In this study new technologies for increasing energy efficiency (EE) in natural gas delivery and consumption sub sectors are discussed and evaluated according to available infrastructures in Iran.

Natural gas outlook

Molyneaux, M.P.

1998-01-01

An overview of natural gas markets in Canada and in the United States was provided. The major factors that determine the direction of natural gas prices were depicted graphically. Price volatility has decreased in recent months. As expected, April through November total energy consumption reached historically high levels. Demand for natural gas during the summer of 1997 was not as strong as anticipated. Nuclear energy appears to be on the slippery slope, with natural gas-driven electricity projects to fill the void. Hydroelectricity had a strong showing in 1997. Prospects are less bright for 1998 due to above average temperatures. Canadian natural gas export capacity has increased 5.5 times between 1986 and estimated 1999 levels. Despite this, in 1997, deliveries to the United States were marginally behind expectations. Natural gas consumption, comparative fuel prices, natural gas drilling activity, natural gas storage capacity, actual storage by region, and average weekly spot natural gas prices, for both the U. S. and Canada, were also provided. With regard to Canada, it was suggested that Canadian producers are well positioned for a significant increase in their price realization mostly because of the increase in Canada's export capacity in 1997 (+175 Mmcf/d), 1998 (1,060 Mmcf/d) and potentially in 1999 or 2000, via the Alliance Pipeline project. Nevertheless, with current production projections it appears next to impossible to fill the 10.9 Bcf/d of export capacity that will be potentially in place by the end of 1999. tabs., figs

The Natural Gas Transmission and Distribution Model (NGTDM) is the component of the National Energy Modeling System (NEMS) that is used to represent the domestic natural gas transmission and distribution system. NEMS was developed in the Office of integrated Analysis and Forecasting of the Energy information Administration (EIA). NEMS is the third in a series of computer-based, midterm energy modeling systems used since 1974 by the EIA and its predecessor, the Federal Energy Administration, to analyze domestic energy-economy markets and develop projections. The NGTDM is the model within the NEMS that represents the transmission, distribution, and pricing of natural gas. The model also includes representations of the end-use demand for natural gas, the production of domestic natural gas, and the availability of natural gas traded on the international market based on information received from other NEMS models. The NGTDM determines the flow of natural gas in an aggregate, domestic pipeline network, connecting domestic and foreign supply regions with 12 demand regions. The methodology employed allows the analysis of impacts of regional capacity constraints in the interstate natural gas pipeline network and the identification of pipeline capacity expansion requirements. There is an explicit representation of core and noncore markets for natural gas transmission and distribution services, and the key components of pipeline tariffs are represented in a pricing algorithm. Natural gas pricing and flow patterns are derived by obtaining a market equilibrium across the three main elements of the natural gas market: the supply element, the demand element, and the transmission and distribution network that links them. The NGTDM consists of four modules: the Annual Flow Module, the Capacity F-expansion Module, the Pipeline Tariff Module, and the Distributor Tariff Module. A model abstract is provided in Appendix A

Natural gas: An essential source of energy in the Romanian economy

International Nuclear Information System (INIS)

Coconea, G.

1993-01-01

The Romanian natural gas industry has existed since the early 1900s. The share of natural gas in Romania's current energy consumption is around 40%. The state gas company Romgaz operates ca 150 gas fields and 3,600 producing wells, but only 20% of annual production is being replaced by new discoveries. Declining gas production is caused by such factors as improper well completion, delayed workovers, water encroachment, and sand consolidation. Romgaz also transports imported natural gas from Russia and provides transportation services to natural gas importers in neighboring countries. The gas transmission network comprises ca 11,000 km of pipelines and 82,800 kW of installed compressor capacity. The distribution system supplies gas to over 2.5 million customers over some 15,000 km of pipeline. Future projects include expansion of production and increasing recoverable reserves, modernization of equipment, constructing an interconnecting pipeline with the Ukraine, installing a liquefied natural gas terminal on the Black Sea, rehabilitating the gas transmission grid, and installing supervisory control and data acquisition systems. The gas consumption pattern of 1990 (57% industrial, 31% power generation, 8% households) is expected to change with a substantial increase in household and commercial supplies, as well as replacement of gas-fired generation with hydroelectric and nuclear generation. A governmental restructuring strategy is being implemented to enhance oil and gas production, to improve operational efficiency of the sector, and to address environmental pollution. Components of the strategy are outlined

Highlights: • Forecasting the recoverable energy from natural gas pressure reduction stations. • Electricity generation through pressure reduction stations via turboexpanders. • A thermodynamics analysis of PRS. - Abstract: Electricity generation or power recovery through pressure reduction stations (PRS) for general use has not been realized in Izmir. The main objective of the present study was to do a case study for calculating electricity to be recovered in one natural gas pressure reduction stations in Izmir. It is the first forecasting study to obtain energy from natural gas pressure-reducing stations in Izmir. Energy can be obtained from natural gas PRS with turbo-expanders instead of using throttle valves or regulators from the PRS. The exergy performance of PRS with TE is evaluated in this study. Exergetic efficiencies of the system and components are determined to assess their individual performances. Based upon pressure change and volumetric flow rate, it can be obtained by recovering average estimated installed capacity and annual energy 494.24 kW, 4113.03 MW h, respectively. In terms of estimated installed capacity power and annual energy, the highest level is 764.88 kW, approximately 6365.34 MW h, in Aliaga PRS. Also it can be seen that CO 2 emission factor average value is 295.45 kg/MW h

Sunoco Inc. is a subsidiary of Suncor Energy, one of Canada's largest integrated energy companies having total assets of $2.8 billion. As one of the major energy suppliers in the country, Sunoco Inc has a substantial stake in the emerging trends in the natural gas industry, including the Canadian natural gas price debate. Traditionally, natural gas prices have been determined by the number of pipeline expansions, weather, energy supply and demand, and storage levels. In addition to all these traditional factors which still apply today, the present day natural gas industry also has to deal with deregulation, open competition and the global energy situation, all of which also have an impact on prices. How to face up to these challenges is the subject of this discourse. tabs., figs

Canadian natural gas and climate change

International Nuclear Information System (INIS)

2002-03-01

The Canadian Gas Association (CGA) has expressed concerns regarding how the goal to reduce greenhouse gas emissions can be met. It also has concerns regarding the possible economic impacts of required measures to reduce emissions to 6 per cent below 1990 levels. The CGA argued that since the initial negotiations of the Kyoto Protocol, Canada's greenhouse gas emissions have increased significantly, meaning that if the agreement were to come into force, Canada would have to reduce emissions by about 29 per cent below the currently-projected 2008-2012 level. The report states that 28 per cent of Canada's energy needs are met by natural gas. Excluding energy use in transportation, natural gas contributes more than 40 per cent to Canada's energy portfolio. More than half of Canadian households rely on pipeline services and distribution companies to deliver natural gas for household use. The manufacturing sector relies on natural gas for more than half of its energy needs. Natural gas is a major energy source for the iron/steel, petroleum refining and chemical manufacturing industries. Natural gas is a cleaner-burning fuel than coal or crude oil, and its use results in fewer environmental impacts than other fossil fuels. Vehicles powered by natural gas produce 20 - 30 per cent less carbon dioxide emissions than vehicles powered by gasoline. Pipelines are also a more efficient way of transporting and distributing natural gas than marine transport, railways or trucks. The CGA recommends that policy development should emphasize the environmental benefits of natural gas and recognize its role as a bridge fuel to a cleaner energy-based economy. It also recommends that policies should be developed to encourage the use of natural gas in electricity generation to lower greenhouse gases and air pollutants such as oxides of nitrogen that cause smog

Natural gas: redistributing the economic surplus

The natural gas has a limited role in the Brazilian energy balance. This role in industrial countries and some developing countries is much more important. Historically this contrasting situation can be explained by the limited natural gas reserves Brazil used to have. Since the oil crisis however the Brazilian natural gas reserves increased substantially without a similar increase in the role of natural gas in the energy balance. The existing institutional arrangement generates a struggle for the economic rent generated by natural gas production and consumption that seems to be at the core of this question. Our paper estimates the economic rent generated by natural gas in Brazil and its distribution among producers and consumers: it points toward a new institutional arrangement that could arguably, generate a new role for the natural gas in the Brazilian energy balance.

The state of Quebec's energy industry was discussed at this conference. Quebec's energy market is distinct by the diversity of its clients, the resource exploitation sector and its types of industries. As such, the energy needs are specific and the strategies for developing natural gas should be adapted to meet these needs. This conference focused on recent energy policy developments at Quebec's Office of Energy and other regulatory bodies. Topics of discussion included the risks and opportunities of the natural gas export market; volatile gas prices; public consultation processes; perspectives of large energy consumers; hydrocarbon potential and exploration in Quebec; natural gas exploration and development in Quebec; energy security and strategies to address carbon dioxide emissions. Other topics of discussion included the investment climate in Quebec; the profitability of Canada's oil and gas sector and refining capacity in Quebec. The conference featured 17 presentations, of which 6 have been indexed separately for inclusion in this database. refs., tabs., figs

Natural gas reserves/total energy consumption: a useful new ratio for addressing global climate change concerns

International Nuclear Information System (INIS)

Siddiqi, T.A.

2002-01-01

Energy analysts have used the reserves/production ratios for oil and natural gas for decades as indicators of the ability of countries to maintain or increase their production of those fuels. The global community is now faced with the challenge of reducing carbon dioxide emissions from a variety of sources, with the energy sector being the largest contributor to the anthropogenic emissions of greenhouse gases. Natural gas has emerged as a highly desirable fuel, since it produces lower emissions of carbon dioxide than coal or oil for equivalent amounts of energy supplied. The ratio of a country's proven natural gas reserves to its total energy consumption is a good indicator of its ability to improve its air quality situation or address greenhouse gas reduction targets from domestic natural gas sources. This paper provides the ratio for several countries at different stages of development, and discusses some of the implications. In countries where exploration for natural gas has been limited, the estimated resources in place may sometimes be a more useful indicator than proven reserves, and could be used instead. (author)

This document comprises the Department of Energy (DOE) Natural Gas Multi-Year Program Plan, and is a follow-up to the `Natural Gas Strategic Plan and Program Crosscut Plans,` dated July 1995. DOE`s natural gas programs are aimed at simultaneously meeting our national energy needs, reducing oil imports, protecting our environment, and improving our economy. The Natural Gas Multi-Year Program Plan represents a Department-wide effort on expanded development and use of natural gas and defines Federal government and US industry roles in partnering to accomplish defined strategic goals. The four overarching goals of the Natural Gas Program are to: (1) foster development of advanced natural gas technologies, (2) encourage adoption of advanced natural gas technologies in new and existing markets, (3) support removal of policy impediments to natural gas use in new and existing markets, and (4) foster technologies and policies to maximize environmental benefits of natural gas use.

The Brazilian energy matrix has been showing a huge increase in the demand of natural gas due mainly to industries and power plants. Today the Brazilian gas market is supplied with gas produced by PETROBRAS and imported from Bolivia. To increase the Brazilian gas supply, on the short and middle term, PETROBRAS will import LNG (liquefied natural gas) and exploit the new offshore fields discovered on the pre-salt area. The only proven technology available today to bring this offshore gas to the market is the pipeline, but its costs for the pre-salt area are high enough to keep the solution economically attractive. So, PETROBRAS are evaluating and developing alternative ways to transport offshore gas, such as LNG, CNG (Compressed Natural Gas), GTS (Gas-to-Solids or Natural Gas Hydrates) and ANG (Adsorbed Natural Gas). Using information available in the literature, this paper analyses the main concepts of CNG and LNG floating unities. This paper also presents the PETROBRAS R and D results on ANG and GTS aiming at offshore application. (author)

LNG [liquefied natural gas]: Fueling energy demand in the Far East

International Nuclear Information System (INIS)

Brown, R.L.

1993-01-01

An overview is presented of the supply and demand outlook for liquefied natural gas (LNG) in the far east, and the basic elements of an LNG supply project in Japan. Power generation is the primary market for LNG in the far east, due to a preference for energy supply diversity, large undeveloped gas resources, drastic improvements in power generation technology, and environmental advantages of natural gas. India and mainland China represent huge potential markets, and projects are under discussion to bring gas by pipeline from Iran or Qatar to both Pakistan or India. The economics of LNG plant development in Japan, including large ($4 billion for field and plant development) capital costs, long-term contracts, government involvement, and gas prices are discussed. Falling yen/dollar exchange rates have substantially bettered the Japanese economy in terms of gas prices. 11 figs., 2 tabs

Following a decade-long upsurge in the use of natural gas in the energy sector (heating and especially electricity), new outlets for natural gas are being developed in the transport sector. For countries endowed with substantial local resources, development in this sector can help reduce oil dependence. In addition, natural gas is often used to reduce pollution, particularly in cities

US crude oil, natural gas, and natural gas liquids reserves: 1990 annual report

International Nuclear Information System (INIS)

1991-09-01

The primary focus of this report is to provide an accurate estimate of US proved reserves of crude oil, natural gas, and natural gas liquids. These estimates were considered essential to the development, implementation, and evaluation of natural energy policy and legislation. In the past, the government and the public relied upon industry estimates of proved reserves. These estimates were prepared jointly by the American Petroleum Institute (API) and the American Gas Association (AGA) and published in their annual report, Reserves of Crude Oil, Natural Gas Liquids, and Natural Gas in the United States and Canada. However, API and AGA ceased publication of reserves estimates after their 1979 report. By the mid-1970's, various federal agencies had separately established programs to collect data on, verify, or independently estimate domestic proved reserves of crude oil or natural gas. Each program was narrowly defined to meet the particular needs of the sponsoring agency. In response to recognized need for unified, comprehensive proved reserves estimates, Congress in 1977 required the Department of Energy to prepare such estimates. To meet this requirement, the EIA's reserves program was undertaken to establish a unified, verifiable, comprehensive, and continuing statistical series for proved reserves of crude oil and natural gas. The program was expanded to include proved reserves of natural gas liquids in the 1979 report. 36 refs., 11 figs., 16 tabs

Natural gas: an environmental-friendly solution?

International Nuclear Information System (INIS)

Vermeire, J.

1994-01-01

Since 1970, the portion of natural gas in energy consumption in Western-Europe has grown by 6 percent per year on the average. About 20 percent of the energy demand in Western-Europe is now covered by natural gas. It is forecasted that this growth will continue at a rate of 2 percent per year until 2010. The natural gas consumption will increase from 325 billion cubic metres in 1993 to 450 billion cubic metres per year in 2010. For the coming 10 to 15 years, the natural gas demand is covered by long-term contracts with gas producing countries. From 2010 on, additional contracts, covering 70 to 120 billion cubic metres per year are required. A shift in geographic distribution of countries from which natural gas will be imported by Western-European countries is expected, which implies high investments and additional costs for transport and distribution of natural gas. Due to its qualities with respect to environmental impact, yield, availability, and advanced technology, natural gas is the energy vector of the 21 first century. (A.S.)

Natural gas purchasing

Freedenthal, C.

1993-01-01

In recent years, natural gas has gained new momentum because of changes in marketing and regulations. The gas industry has always received an inordinate amount of regulatory control starting at the well head where the gas is produced to the consuming burner tip. Regulations have drastically impacted the availability of gas. Changes in the marketing and regulations have made the natural gas market sensitive at the point of production, the well head. Now, with plentiful supply and ease of transportation to bring the gas from the producing fields to the consumer, natural gas markets are taking advantage of the changed conditions. At the same time, new markets are developing to take advantage of the changes. This section shows consumers, especially the energy planners for large buyers of fuel, the advantages, sources and new methods of securing natural gas supplies. Background on how natural gas is produced and marketed are given. This section lists marketing sources, regulatory agencies and information groups available to help buyers and consumers of this important fuel for US industries and residences. 7 figs., 8 tabs

Fernandes, Elton; Fonseca, Marcus Vinicius de A; Alonso, P.S.R.

2005-01-01

This paper describes and analyzes the constraints hampering achievement of the 12% share planned for natural gas in Brazil's energy matrix by 2010, and advises policies for reaching that goal on the basis of forecasts and three probable scenarios for the development of the Brazilian economy. The 12% share goal was established in 1993 by the Ministry of Mines and Energy and confirmed in 2000, and is now in full development. The figures used to represent the estimates of natural gas demands in the three scenarios were obtained from the Integrated Energy Planning Model (MIPE--Modelo Integrado de Planejamento Energetico), which is a technical and economic forecasting model developed by a group of researchers linked to the Energy Planning Program run by the Graduate Engineering Programs Coordination Unit at the Rio de Janeiro Federal University (COPPE-UFRJ) under the sponsorship of Petrobras (a Brazilian enterprise operating in the oil and gas segment) and Eletrobras (a Brazilian enterprise in charge of electricity demand planning). The analysis of the constraints take place under the aegis of the objective proposed by the Brazilian Government. The authors suggest specific actions to be taken in four application areas of natural gas: industrial, electric power generation, domestic distribution and vehicular fleet conversions. All the actions proposed encourage the use of a fuel with low environmental impacts and high calorie power, replacing firewood and other polluting fuels and are evaluated relative to the impacts occurring in society, especially from the standpoint of social welfare in a developing country. The necessity of developing the goods and services infrastructure in the country to support the natural gas insertion in the Brazilian energy matrix is also addressed

Natural gas for New Brunswick: First report

International Nuclear Information System (INIS)

1998-01-01

The development of the gas field off Sable Island and the imminent construction of a gas pipeline which will deliver natural gas to New Brunswick has prompted a thorough examination of energy-related issues in the province. This report presents the findings of the provincial energy committee which examined the implications of the arrival of natural gas to the province. The committee held a series of public hearings and consultations, and also received written submissions. After a historical perspective on natural gas as an energy source in the province and a review of the gas industry participants and their interests, the report discusses such issues as gas pipeline economics, local distribution company operations, infrastructure development, the regulatory framework, energy market competition, regional price equity, development of in-province gas sources, pipeline access, pipeline laterals and expansions, establishment of gas distribution franchises, municipal involvement in gas development, the impact of gas industry development on electric utility restructuring, and the environmental benefits of natural gas. Finally, recommendations are made regarding how natural gas should be regulated and distributed

Natural gas supply, demand and price outlook

Natural gas consumption in the US grew 15.9 percent between 1986 and 1989. Its share of total primary energy use in the US grew from 22.5 percent to 23.8 percent. Despite unusually warm weather and an economic downturn, natural gas use in the first eight months of 1990 fell only modestly from its 1989 pace - while its market share of US total primary energy use has remained stable. The American Gas Association's Total Energy Resource Analysis energy modeling system (A.G.A.-TERA) projects continued growth in natural gas demand and supply. Natural gas is projected to gain a growing share of total US primary use. Natural gas prices are projected to be sufficient to encourage growth in well completions and reserve additions, yet competitive with electricity, fuel oil and other alternative forms of energy

The contribution of the DOE's R ampersand D budget in natural gas to energy price security

International Nuclear Information System (INIS)

Sutherland, R.J.

1992-01-01

The energy price volatility model suggests that some of the proposed natural gas programs can contribute to energy price stability. The sector most vulnerable to fuel price variations is, of course, the transportation sector. The most effective strategy to achieve energy pace stability is to reduce petroleum consumption in this sector. The natural gas vehicle program is therefore recommended as potentially important and worthy of further consideration. At this point, distinguishing the merits of various subprograms is not feasible. This result farther supports the conclusion that the DOE's energy R ampersand D portfolio is not efficiently balanced and an increase in oil and gas research should be a high priority. The DOE has responded favorably and has significantly increased its proposed research with the explicit objective of displacing oil in the transportation sector. The enhanced research and development program for energy security, in the NES, proposes major funding, increases in this area. To recommend the further increases proposed by the industry, a careful analysis of incremental benefits and costs is required. The proposed natural as supply program is intended to enhance the future supply of natural gas. As explained above, enhanced gas supplies can reduce the volatility of gas prices and severe the link between gas and oil prices. The gas supply program is recommended as a potentially important strategy to ensure energy price stability. The importance of this point merits restatement. Oil price volatility affects directly the transportation and industrial sectors. The residential, commercial and electric utility sectors are not highly oil dependent. However, oil prices have affected gas prices and gas is used extensively the residential, commercial, industrial and electric utility sectors. Energy price stability is enhanced in these sectors by severing, the link, between oil and gas prices

Use of natural gas for swimming facilities: Energy savings and environmental compatibility

International Nuclear Information System (INIS)

Ciocca, B.

1992-01-01

In the last twenty years, natural gas consumption has greatly increased in the civil sector and this trend will be confirmed in the next decade which will have a considerable increase in the domestic Italian distribution and in national supply networks. Swimming centres, particularly those equipped with covered swimming-pools and therefore characterized by continuous operation during the year, have significant energy consumption, with the same volume, compared with other civil users. This is due not only to the particular operating characteristics of the swimming pool but, in most cases, to the little attention payed to running costs and thus to energy savings. Natural gas, as a versatile fuel of good quality, can offer a valid contribution to the limitation of the energy consumption of swimming centres, as well as, to the abatement of air pollution, in particular, if it is employed together with new technologies such as the cogeneration and gas fuelled heat pumps

The experts of energy policy agree to predict a brilliant future for natural gas. Among fossil energies, natural gas produces the least quantity of CO 2 . Geological reserves are estimated to 65 years for gas and 43 years for petroleum. Throughout the world, industrial infrastructures of gas production, transport and distribution are being developed, for instance 430000 km of gas pipeline are planned. In western Europe half the increase of gas demand by 2010 will be due to electricity production. Innovative techniques using natural gas are studied in various fields: cogeneration, transport, urban heating and fuel cells. The gas-fed fuel cell is based on a reversed electrolysis: hydrogen produced by the decomposition of natural gas interacts with oxygen and yields electricity. (A.C.)

2008-01-01

Recent studies in Japan have suggested that natural gas hydrate (NGH) transportation of natural gas is more economical than liquefied natural gas (LNG) transportation systems for small, medium and remote gas fields. Researchers in Japan have built a 600 kg per day NGH production and pelletizing plant and regasification facility. This paper discussed feasibility studies conducted in southeast Asia to determine the unit's commercialization potential with large natural gas-related businesses including shipping companies and electric power utilities. The total supply chain was compared with the corresponding liquefied natural gas (LNG) and compressed natural gas (CNG) supply chains. The study also examined natural gas reserves, energy policies, the positioning of natural gas supplies, and future forecasts of natural gas demand. A conceptual design for an NGH supply chain in Indonesia was presented. Results of the study have demonstrated that the NGH chain is an appropriate and economically feasible transportation method for many areas in southeast Asia. 8 refs., 10 figs

Natural gas was for a long time reserved to the most noble uses in the industry. However, natural gas, which get a priori no captive market, has progressively imposed itself in all possible energy uses. The gas resources and abundant enough to represent the main contribution of the energy industry of the 21 century. With intrinsic qualities which make it an energy less polluting than the other fossil fuels, natural gas is the commercial energy source with the highest potential growth in the energy status of the future.

Effect of Energy Efficiency Standards on Natural Gas Prices

Energy Technology Data Exchange (ETDEWEB)

Carnall, Michael; Dale, Larry; Lekov, Alex

2011-07-26

A primary justification for the establishment of energy efficiency standards for home appliances is the existence of information deficiencies and externalities in the market for appliances. For example, when a long-term homeowner purchases a new gas-fired water heater, she will maximize the value of her purchase by comparing the life-cycle cost of ownership of available units, including both total installed cost - purchase price plus installation costs - and operating cost in the calculus. Choice of the appliance with the lowest life-cycle costs leads to the most economically efficient balance between capital cost and fuel cost. However, if the purchaser's expected period of ownership is shorter than the useful life of the appliance, or the purchaser does not pay for the fuel used by the appliance, as is often the case with rental property, fuel cost will be external to her costs, biasing her decision toward spending less on fuel efficiency and resulting in the purchase of an appliance with greater than optimal fuel usage. By imposing an efficiency standard on appliances, less efficient appliances are made unavailable, precluding less efficient purchases and reducing fuel usage. The reduction in fuel demanded by residential users affects the total demand for such fuels as natural gas, for example. Reduced demand implies that residential customers are willing to purchase less gas at each price level. That is, the demand curve, labeled D{sub 0} in Figure 1, shifts to the left to D{sub 1}. If there is no change in the supply function, the supply curve will intersect the demand curve at a lower price. Residential demand is only one component of the total demand for natural gas. It is possible that total demand will decline very little if demand in other sectors increases substantially in response to a decline in the price. If demand does decrease, modeling studies generally confirm the intuition that reductions in demand for natural gas will result in reductions

In 1998, Southwest Research Institute began a multi-year project to develop a working prototype instrument module for natural gas energy measurement. The module will be used to retrofit a natural gas custody transfer flow meter for energy measurement, at a cost an order of magnitude lower than a gas chromatograph. Development and evaluation of the prototype energy meter in 2002-2003 included: (1) refinement of the algorithm used to infer properties of the natural gas stream, such as heating value; (2) evaluation of potential sensing technologies for nitrogen content, improvements in carbon dioxide measurements, and improvements in ultrasonic measurement technology and signal processing for improved speed of sound measurements; (3) design, fabrication and testing of a new prototype energy meter module incorporating these algorithm and sensor refinements; and (4) laboratory and field performance tests of the original and modified energy meter modules. Field tests of the original energy meter module have provided results in close agreement with an onsite gas chromatograph. The original algorithm has also been tested at a field site as a stand-alone application using measurements from in situ instruments, and has demonstrated its usefulness as a diagnostic tool. The algorithm has been revised to use measurement technologies existing in the module to measure the gas stream at multiple states and infer nitrogen content. The instrumentation module has also been modified to incorporate recent improvements in CO{sub 2} and sound speed sensing technology. Laboratory testing of the upgraded module has identified additional testing needed to attain the target accuracy in sound speed measurements and heating value.

Agricultural demands for natural gas and liquified petroleum gas in the USA

1992-01-01

This study endeavours to determine whether farmers adjust their consumption of natural gas and liquefied petroleum gas in response to changes in the unit price of energy. A demand model is specified and estimated. The conclusions suggest that the unit price of natural gas (liquefied petroleum gas) is a factor impacting the quantity of natural gas (liquefied petroleum gas) demanded by farmers, but there is no indication that other types of energy are substitutes for natural gas or liquefied petroleum gas. Additionally, the number of acres irrigated is an important factor driving the demand for natural gas and liquefied petroleum gas. Finally, the estimated models of natural gas and liquefied petroleum gas demand were structurally stable over the period 1971-1989. (author)

As natural gas is about to become the first energy source in the world, is abundant and easy to transport, this collective publication addresses issues related to shale gas and to natural gas. The first part addresses shale gas. Four articles propose a global overview, comment the situation in the USA which, in eight years of time, reduced their oil dependency by half and became almost self-sufficient as far as gas is concerned, discuss technical and legal issues related to shale gas exploitation, discuss the perspective of evolution of the world gas markets, and notice that shale gas will not be a game changer in Europe. The second part addresses the natural gas. The articles discuss the possible influence of natural gas exploitation by Israel on the Middle-East geopolitical situation, the influence of the emergence of new producers in Africa (Tanzania and Mozambique), the contribution of gas-fuelled power station to the coverage of market risks, and the issue of European energy safety with a focus on the role of Turkey

Natural gas : a highly lucrative commodity

Exploration and production of natural gas has become highly profitable as natural gas is becoming a leading future commodity. With new technology, high demand and environmental benefits, natural gas is the preferred choice over petroleum as the leading source of energy to heat home and businesses. Canada is the world's third largest producer of natural gas with its Sable Offshore Energy Project being the fourth largest producing natural gas basin in North America. The basin will produce high quality sweet natural gas from 28 production wells over the course of the next 20 to 25 years. The gas will be transported to markets through Nova Scotia, New Brunswick and into the Northeastern United States via the Maritimes and Northeast Pipeline. The 1051 kilometer underground gas pipeline is currently running laterals to Halifax, Nova Scotia and Saint John, New Brunswick. Market studies are being conducted to determine if additional lines are needed to serve Cape Breton, Prince Edward Island and northern New Brunswick. A recent survey identified the following 5 reasons to convert to natural gas: (1) it is safe, (2) it is reliable, (3) it is easy to use, (4) it is cleaner burning and environmentally friendly compared to other energy sources, and (5) it saves the consumer money

This work aims the economics and the viability of Natural Gas Industrialization in Bolivia, by producing secondary fuels like gas to liquid (GTL)-diesel from natural gas (cleaner than the oil by-product), looking for a clean development with that environmentally well energy using this GTL process. Bolivia has resources that could fulfill these secondary energy resources from GTL. It is possible to process 30 MCMpd of gas obtaining profits from the gas and also from the liquid hydrocarbons that are found in it. Then the Bolivian GTL would present the following advantages: it would export diesel and/or gasoline and would not have to import it anymore.; the exportations of GTL-FT would reach 35 Mbpy, acquiring competitive prices; it would increase productive jobs not only due to the GTL itself, but also from secondary economy linked to GTL market; the use of GTL-FT diesel would bring a ''cleaner'' environment especially in the urban areas; finally, from the macroeconomic perspective, the investment in the plant construction and supporting works would generate a great amount of job offers.

Natural gas supply in Denmark - A model of natural gas transmission and the liberalized gas market

International Nuclear Information System (INIS)

Bregnbaek, L.

2005-01-01

In the wake of the liberalization of European energy markets a large area of research has spawned. This area includes the development of mathematical models to analyze the impact of liberalization with respect to efficiency, supply security and environment, to name but a few subjects. This project describes the development of such a model. In Denmark the parallel liberalization of the markets of natural gas and electricity and the existence of an abundance of de-centralized combined heat and power generators of which most are natural gas fired, leads to the natural assumption that the future holds a greater deal of interdependency for these markets. A model is developed describing network flows in the natural gas transmission system, the main arteries of natural gas supply, from a technical viewpoint. This yields a technical bounding on the supply available in different parts of the country. Additionally the economic structure of the Danish natural gas market is formulated mathematically giving a description of the transmission, distribution and storage options available to the market. The supply and demand of natural gas is put into a partial equilibrium context by integrating the developed model with the Balmorel model, which describes the markets for electricity and district heat. Specifically on the demand side the consumption of natural gas for heat and power generation is emphasized. General results and three demonstration cases are presented to illustrate how the developed model can be used to analyze various energy policy issues, and to disclose the strengths and weaknesses in the formulation.

Afgan, Naim H.; Pilavachi, Petros A.; Carvalho, Maria G.

2007-01-01

Geologically estimated natural gas resources are 500 Tcm. With the advance in geological science increase of estimated resources is expected. Natural gas reserves in 2000 have been proved to be around 165 Tcm. As it is known the reserves are subject to two constraints, namely: capital invested in the exploration and drilling technologies used to discover new reserves. The natural gas scarcity factor, i.e. ratio between available reserves and natural gas consumption, is around 300 years for the last 50 years. The new discovery of natural gas reserves has given rise to a new energy strategy based on natural gas. Natural gas utilization is constantly increasing in the last 50 years. With new technologies for deep drilling, we have come to know that there are enormous gas resources available at relatively low price. These new discoveries together with high demand for the environment saving have introduced a new energy strategy on the world scale. This paper presents an evaluation of the potential natural gas utilization in energy sector. As the criteria in this analysis resource, economic, environmental, social and technological indicators are used. Among the potential options of gas utilization following systems are considered: Gas turbine power plant, combine cycle plant, CHP power plant, steam turbine gas-fired power plant, fuel cells power plant. Multi-criteria method was used for the assessment of potential options with priority given to the Resource, Economic and Social Indicators. Results obtained are presented in graphical form representing priority list of potential options under specific constraints in the priority of natural gas utilization strategy in energy sector

Venezuela natural gas outlook

International Nuclear Information System (INIS)

Silva, P.

1991-01-01

This paper reports on the natural gas outlook for Venezuela. First of all, it is very important to remember that in the last few years we have had frequent and unforeseen changes in the energy, ecological, geopolitical and economical fields which explain why all the projections of demand and prices for hydrocarbons and their products have failed to predict what later would happen in the market. Natural gas, with its recognized advantages over other traditional competitors such as oil, coal and nuclear energy, is identified as the component that is acquiring more weight in the energy equation, with a strengthening projection, not only as a resource that covers demand but as a key element in the international energy business. In fact, natural gas satisfies 21% of overall worldwide energy consumption, with an annual increase of 2.7% over the last few years, which is higher than the global energy growth of other fossil fuels. This tendency, which dates from the beginning of the 1980's, will continue with a possibility of increasing over the coming years. Under a foreseeable scenario, it is estimated that worldwide use of natural gas will increase 40% over the next 10 years and 75% on a longer term. Specifically for liquid methane (LNG), use should increase 60% during this last decade. The LPG increase should be moderate due to the limited demand until 1995 and to the stable trends that will continue its use until the end of this century

Owing to the technological development of natural gas exploration and the increasing penetration of gas-fired power generation, gas and power systems inevitably interact with each other from both physical and economic points of view. In order to effectively assess the two systems' interdependency, this paper proposes a systematic modeling framework and constructs simulation platforms for coupled gas and power systems in an energy market environment. By applying the proposed approach to the Australian national electricity market (NEM) and gas market, the impacts of six types of market and system factors are quantitatively analyzed, including power transmission limits, gas pipeline contingencies, gas pipeline flow constraints, carbon emission constraints, power load variations, and non-electric gas load variations. The important interdependency and infrastructure weakness for the two systems are well studied and identified. Our work provides a quantitative basis for grid operators and policy makers to support and guide operation and investment decisions for electric power and natural gas industries.

A study was conducted to find practical ways to reduce Ontario's energy consumption and environmental emissions. A major portion of the study focused on the advantages of cogeneration in certain regions and sectors of Ontario. Substituting direct fuel heating with natural gas for electric heating was the principal recommendation. Results of a technical analysis of the effects of substituting electric heating with natural gas heating were described. One of the benefits of this substitution would be reduced fuel energy requirements for direct heating, relative to the two-step process of electricity generation followed by electric heating. It was suggested that natural gas should still be used for electricity generation because natural gas has many advantages as an electricity supply option including reductions in coal and uranium use and related emissions. It was recommended that developers and designers of energy systems seriously consider this option. 33 refs., 2 tabs., 4 figs

Israel-New natural gas producer in the Mediterranean

In 2009 and 2010, major offshore natural gas reserves were discovered near the State of Israel. This article examines Israel's newly discovered natural gas reserves and the implications of this discovery for Israel, the Middle East, and the Mediterranean region. The article will discuss Israel's energy security approach; the role of natural gas in Israel's energy consumption patterns; the organization of Israel's natural gas sector; regional political and security implications of the natural gas discoveries; the prospects for export, and the outlook for various natural gas markets. These new discoveries significantly improve Israel's energy security. They may also spur Israel to develop technologies related to utilization of natural gas in a variety of sectors, such as transportation. The discoveries may contribute to the emergence of a number of maritime border delimitation conflicts in the Eastern Mediterranean. At current volumes, the Israeli discoveries will not be a game-changer for gas markets in southern Europe or liquefied natural gas (LNG) markets. However, they will lead to expanded natural gas consumption in the region. In addition, offshore exploration efforts in Israel and in neighboring countries are intensifying. Additional discoveries may turn the Eastern Mediterranean region into a new source of natural gas and oil. - Highlights: → In 2009 and 2010, major natural gas deposits were discovered offshore of Israel's port city of Haifa. → They will satisfy a large portion of Israel's domestic energy consumption needs for a number of decades. → The gas discoveries have created an opportunity to fundamentally change the country's energy policies. → Additional discoveries may turn the Eastern Mediterranean region into a new source of natural gas and oil. → Israel could become a supplier of natural gas to neighbors in the Middle East region, such as Jordan.

Outlook for the continued convergence of natural gas and electricity markets and the impact on energy consumers

International Nuclear Information System (INIS)

DeWolf, R.

This presentation discussed the implications of converging natural gas and electricity markets with reference to natural gas supply, demand and prices. Convergence is an outcome of the increasing use of natural gas in power generation. The author stated his view that convergence of natural gas and electricity will continue, and even increase. The issue of deliverability versus reserves in North America was discussed. While both Canada and the United States have significant existing natural gas reserves, the deliverability is declining and incremental production will come at higher prices because of production challenges in remote and untapped regions. Outlooks by the Alberta Energy and Utilities Board and the National Energy Board indicate that traditional and maturing supply basins in Alberta will not be able to maintain the existing level of production. British Columbia has production opportunities, but they are offshore, and optimism for offshore production in eastern Canada is mixed. Gas supply in the United States is not expected to meet demand expectations. This presentation outlined incremental natural gas supplies for northern Canada, coalbed methane, eastern Canada, and offshore British Columbia. It also outlined the challenges of liquefied natural gas (LNG) projects in Canada, the United States and Mexico. The forecast for increasing natural gas prices has raised the issue of looking at alternatives to natural gas for power generation, but environmental issues continue to favour natural gas. tabs., figs

Green future of natural gas

A sectoral analysis of current trends in the use of natural gas in Italy shows that this energy source, now estimated to be covering 23.7% of total Italian national energy requirements, is fulfilling its role as an environmentally compatible, low cost and readily available energy alternative well suited to alleviate Italy's worrisome over-dependence on foreign supplied oil and reduce the severity of the urban air pollution problem (it being a low nitrogen oxide and carbon dioxide emitting, non-sulfur containing fuel). This paper expands this theme by giving a complete panorama of the natural gas market in Italy, sector by sector, and by coupling projections on the expected increased use of this energy source (as mandated by the National Energy Plan) with estimates of consequent reductions in air pollution based on a comparative analysis of fuel oil versus natural gas combustion

Ensuring the resilience, reliability, flexibility, and affordability of the U.S. electric grid is increasingly important as the country addresses climate change and an aging infrastructure. State and federal policy and actions by industry, non-profits, and others create a dynamic framework for achieving these goals. Three principle low-carbon generation technologies have formed the basis for multiple scenarios leading toward a low-carbon, resilient, and affordable power system. While there is no “silver bullet,” one avenue identified by key stakeholders is the opportunity to invest in natural gas (NG) and renewable resources, both of which offer abundant domestic resource bases and contribute to energy independence, carbon mitigation, and economic growth. NG and renewable electricity (RE) have traditionally competed for market share in the power sector, but there is a growing experience base and awareness for their synergistic use (Cochran et al. 2014). Building upon these observations and previous work, the Joint Institute for Strategic Energy Analysis (JISEA), in collaboration with the Center for the New Energy Economy and the Gas Technology Institute, convened a series of workshops in 2014 to explore NG and RE synergies in the U.S. power sector. This report captures key insights from the workshop series, Synergies of Natural Gas and Renewable Energy: 360 Degrees of Opportunity, as well as supporting economic valuation analyses conducted by JISEA researchers that quantify the value proposition of investing in NG and RE together as complements.

In Croatia, natural gas is an important source of energy, where its use exceeds other sources by one third. Composed primarily of the methane, natural gas from Croatian Podravina gas fields, beside other impurities, contains small amounts of radioactive elements. At Gas Treatment Plant (GTP) Molve, technological procedures for purification of natural gas and its distribution are performed. With yearly natural gas production of 3.5 109 m3 GTP Molve is major Croatian energy resource. Its safety and environment impact is matter of concern. Using different radioactivity measuring techniques the exposure of population to ionizing radiation were calculated at Central Natural Gas Station Molve and the underground wells. The measurement techniques included in-situ gamma spectrometric measurements, from which contribution to absorbed dose of the natural radionuclide in soil were calculated. Exposure dose measurements were performed using T.L.-dosimeters, and L.A.R.A. electronic dosimeters as well as field dose rate meter. Comparing used different radioactivity measuring methods, the correlations have been calculated. (authors)

This conference provided insight into how to prosper in an increasingly complex natural gas marketplace. The presentations from key industry players offered valuable information on natural gas purchasing strategies that are working in the current volatile price environment. Diminishing natural gas supplies in North America mean that higher prices and volatility will continue. Other market challenges stem from potential cost increases in gas transportation, unbundling of natural gas services, and the changing energy marketing environment. The main factors that will affect prices for the winter of 2004 were outlined along with risk management and the best pricing strategies for businesses. The key strategies for managing the risks associated with natural gas purchase contracts were also reviewed, along with the issue of converging natural gas and electricity markets and the impact on energy consumers. The conference featured 15 presentations, of which 4 have been indexed separately for inclusion in this database. refs., tabs., figs

This document deals with the foreseeable evolution of natural gas demand in the next 15 years. Natural gas consumption is growing faster than any other fossil fuel and, according to ENRON, the natural consumption growth will continue. The environmental aspect of natural gas use for power generation is presented, showing that gas use reduces pollution emissions (when compared with coal). On top of that, it appears that the conversion efficiency of gas is much higher than the conversion efficiency of coal steam. Eventually, natural gas resources should meet energy demand for decades.

Potential hazards of compressed air energy storage in depleted natural gas reservoirs.

Energy Technology Data Exchange (ETDEWEB)

Cooper, Paul W.; Grubelich, Mark Charles; Bauer, Stephen J.

2011-09-01

This report is a preliminary assessment of the ignition and explosion potential in a depleted hydrocarbon reservoir from air cycling associated with compressed air energy storage (CAES) in geologic media. The study identifies issues associated with this phenomenon as well as possible mitigating measures that should be considered. Compressed air energy storage (CAES) in geologic media has been proposed to help supplement renewable energy sources (e.g., wind and solar) by providing a means to store energy when excess energy is available, and to provide an energy source during non-productive or low productivity renewable energy time periods. Presently, salt caverns represent the only proven underground storage used for CAES. Depleted natural gas reservoirs represent another potential underground storage vessel for CAES because they have demonstrated their container function and may have the requisite porosity and permeability; however reservoirs have yet to be demonstrated as a functional/operational storage media for compressed air. Specifically, air introduced into a depleted natural gas reservoir presents a situation where an ignition and explosion potential may exist. This report presents the results of an initial study identifying issues associated with this phenomena as well as possible mitigating measures that should be considered.

Natural gas vehicles. An option for Europe

International Nuclear Information System (INIS)

Engerer, Hella; Horn, Manfred

2010-01-01

In Europe natural gas vehicles play a minor role. A decisive reason for this is the dependence of most European countries from gas imports. Except for Italy, there is no tradition to use natural gas as fuel. In addition, there is a lack of infrastructure (e.g. fuelling stations). In contrast to Europe, in Latin American and Asian countries natural gas vehicles are widespread. Some countries foster natural gas vehicles because they have own gas resources. Many countries must reduce the high air pollution in big cities. Environmental reasons are the main motive for the use of natural gas vehicles in Europe. In last years, high oil prices stimulated the use of natural gas as fuel. European governments have developed incentives (e.g. tax reductions) to foster natural gas vehicles. However, the focus is on hybrid technology and the electric car, which, however, need further technical improvement. In contrast, the use of natural gas in conventional engines is technically mature. Additional gas imports can be avoided by further improvements of energy efficiency and the use of renewable energy. In sum, the market penetration of natural gas as fuel should be promoted in Europe.

The inevitability of an energy transition from today's non-renewable fossil base toward a renewable energy base is considered from the viewpoint of the need for a national transition strategy. Then, one such strategy is offered. Its technological building blocks are described in terms of both energy use and energy supply. The strategy itself is then sketched at four points in its implementation; (1) initiation, (2) early transition, (3) late transition, and (4) completion. The transition is assumed to evolve from a heavily natural gas-dependent energy economy. It then proceeds through its transition toward a balanced, hybrid energy system consisting of both centralized and dispersed energy supply technologies supplying hydrogen and electricity from solar energy. Related institutional, environmental and economic factors are examined briefly.

The role of natural gas in power generation was discussed with reference to price implications and policy recommendations. New natural gas supply is not keeping pace with demand. Production is leveling out in traditional basins and industry investment is not adequate. In addition, energy deregulation is creating disconnects. This presentation included a map depicting the abundant natural gas reserves across North America. It was noted that at 2002 levels of domestic production, North America has approximately 80 years of natural gas. The AECO consensus wholesale natural gas price forecast is that natural gas prices in 2010 will be lower than today. The use of natural gas for power generation was outlined with reference to fuel switching, distributed generation, and central generation. It was emphasized that government, regulators and the energy industry must work together to address policy gaps and eliminate barriers to new investment. 13 figs

Natural gas could be an important alternative energy source in meeting some of the market demand presently met by liquid products from crude oil. This study was initiated to analyze three energy markets to determine if greater use could be made of natural gas or natural gas derived products and if those products could be provided on an economically competitive basis. The three markets targeted for possible increases in gas use were motor fuels, power generation, and the chemical feedstocks market. The economics of processes to convert natural gas to transportation fuels, chemical products, and power were analyzed. The economic analysis was accomplished by drawing on a variety of detailed economic studies, updating them and bringing the results to a common basis. The processes analyzed included production of methanol, MTBE, higher alcohols, gasoline, CNG, and LNG for the transportation market. Production and use of methanol and ammonia in the chemical feedstock market and use of natural gas for power generation were also assessed. Use of both high and low quality gas as a process feed stream was evaluated. The analysis also explored the impact of various gas price growth rates and process facility locations, including remote gas areas. In assessing the transportation fuels market the analysis examined production and use of both conventional and new alternative motor fuels

The ownership structure of Finland's leading natural gas company, Gasum, changed fundamentally in 1999, and the company is now no longer a subsidiary of Fortum Corporation. 'Our new strong and broad ownership base will enable us to develop the natural gas business and pipeline network in Finland in response to the requirements of our Finnish customers', says Antero Jaennes, Gasum's Chairman and CEO, who stresses that Gasum is committed to remaining the leading developer of the Finnish natural gas market and the number-one gas supplier. Natural gas usage in Finland in 1999 totalled 3.9 billion m 3 (38.7 TWh), unchanged from 1998. Natural gas accounted for 11% of Finland's total primary energy need, as it did in 1998. The proportion of natural gas used in district heating rose by 2% to 36%, and moved down 2% in power generation to 10%. Industry's use of natural gas fell 1% to 17%. 75% of natural gas was used in combined heat and power (CHP) generation in industry and district heating. In 2000, Gasum expects to sell 4 billion m 3 of natural gas (40 TWh)

This paper aims to select the optimal energetic scenario applied to a consumer with 100 000 inhabitants from the residential-tertiary sector, from the ecological, energetical and economic points of view. A series of seven scenarios based on natural gas has been analyzed. The authors proposed six scenarios for the combined heat and power generation using existing technologies and one scenario for separate generation of the two energy forms. To compare the seven energetic scenarios, the amount of thermal and electrical energy produced by each one had to be the same for a defined time period. To select the optimal energy scenario a multi-criteria NAIADE-based method has been used. Consequently, the optimal energy scenario has been established with respect to criteria groups: ecologic, economic, energetic and global where all criteria groups have been considered. The study results prove that a combined gas and steam turbine cycle is optimal technically, economically and ecologically as it is for each criteria group. A sensitivity analysis has been performed to establish the influence of various parameters in the identification of the optimal energy scenario.

For more than 25 years the Netherlands and Russia have supplied Italy with natural gas. Consequently, Italy was the first importer that did not receive natural gas from a neighbouring country, but from sources located more than a thousand kilometers away. These gas import pipelines, among other things, made it possible for Italy to grow into one of the largest gas countries in Europe. Today, natural gas accounts for well over a quarter of primary energy consumption and it is expected to reach a 37% peak by the year 2010. Since the 1950s, almost the entire oil and gas industry is owned by the state-owned holding company ENI ('Ente Nazionale Idrocarburi'). Although privatisation has gained momentum, it seems as if this holding will continue to dominate the gas market in the short term, because, in addition to large-scale import, ENI also controls the logistical elements, transmission and storage

The United States relies on natural gas for one-quarter of its energy needs. In 2001 alone, the nation consumed 21.5 trillion cubic feet of natural gas. A large portion of natural gas pipeline capacity within the United States is directed from major production areas in Texas and Louisiana, Wyoming, and other states to markets in the western, eastern, and midwestern regions of the country. In the past 10 years, increasing levels of gas from Canada have also been brought into these markets (EIA 2007). The United States has several major natural gas production basins and an extensive natural gas pipeline network, with almost 95% of U.S. natural gas imports coming from Canada. At present, the gas pipeline infrastructure is more developed between Canada and the United States than between Mexico and the United States. Gas flows from Canada to the United States through several major pipelines feeding U.S. markets in the Midwest, Northeast, Pacific Northwest, and California. Some key examples are the Alliance Pipeline, the Northern Border Pipeline, the Maritimes & Northeast Pipeline, the TransCanada Pipeline System, and Westcoast Energy pipelines. Major connections join Texas and northeastern Mexico, with additional connections to Arizona and between California and Baja California, Mexico (INGAA 2007). Of the natural gas consumed in the United States, 85% is produced domestically. Figure 1.1-1 shows the complex North American natural gas network. The pipeline transmission system--the 'interstate highway' for natural gas--consists of 180,000 miles of high-strength steel pipe varying in diameter, normally between 30 and 36 inches in diameter. The primary function of the transmission pipeline company is to move huge amounts of natural gas thousands of miles from producing regions to local natural gas utility delivery points. These delivery points, called 'city gate stations', are usually owned by distribution companies, although some are owned by

The mission of the US Department of Energy (DOE) Federal Energy Management Program (FEMP) is to lead the improvement of energy efficiency and fuel flexibility within the federal sector. Through the Pacific Northwest Laboratory (PNL), FEMP is developing a fuel-neutral approach for identifying, evaluating, and acquiring all cost-effective energy projects at federal installations; this procedure is entitled the Federal Energy Decision Screening (FEDS) system. Through a cooperative program between FEMP and the Army Forces Command (FORSCOM) for providing technical assistance to FORSCOM installations, PNL has been working with the Fort Lewis Army installation to develop the FEDS procedure. The natural gas and fuel oil assessment contained in this report was preceded with an assessment of electric energy usage that was used to implement a cofunded program between Fort Lewis and Tacoma Public Utilities to improve the efficiency of the Fort's electric-energy-using systems. This report extends the assessment procedure to the systems using natural gas and fuel oil to provide a baseline of consumption and an estimate of the energy-efficiency potential that exists for these two fuel types at Fort Lewis. The baseline is essential to segment the end uses that are targets for broad-based efficiency improvement programs. The estimated fossil-fuel efficiency resources are estimates of the available quantities of conservation for natural gas, fuel oils number-sign 2 and number-sign 6, and fuel-switching opportunities by level of cost-effectiveness. The intent of the baseline and efficiency resource estimates is to identify the major efficiency resource opportunities and not to identify all possible opportunities; however, areas of additional opportunity are noted to encourage further effort

In the United States, recent shale gas discoveries have generated renewed interest in using natural gas as a vehicular fuel, primarily in fleet applications, while outside the United States, natural gas vehicle use has expanded significantly in the past decade. In this report for the U.S. Department of Energy's Clean Cities Program - a public-private partnership that advances the energy, economic, and environmental security of the U.S. by supporting local decisions that reduce petroleum use in the transportation sector - we have examined the state of natural gas vehicle technology, current market status, energy and environmental benefits, implications regarding advancements in European natural gas vehicle technologies, research and development efforts, and current market barriers and opportunities for greater market penetration. The authors contend that commercial intracity trucks are a prime area for advancement of this fuel. Therefore, we examined an aggressive future market penetration of natural gas heavy-duty vehicles that could be seen as a long-term goal. Under this scenario using Energy Information Administration projections and GREET life-cycle modeling of U.S. on-road heavy-duty use, natural gas vehicles would reduce petroleum consumption by approximately 1.2 million barrels of oil per day, while another 400,000 barrels of oil per day reduction could be achieved with significant use of natural gas off-road vehicles. This scenario would reduce daily oil consumption in the United States by about 8%.

Natural gas utilization in the electricity sector in a framework of supporting an energy diversification policy: the case of Indonesia

International Nuclear Information System (INIS)

1992-01-01

Although the Government of Indonesia (GOI) has been trying to balance its economy, oil and gas (MIGAS) sector still has an important role. The revenue from exporting oil has been needed to sustain national economic development. For that reason, the GOI has determined to diversify and to develop alternative energy resources for domestic consumption. The alternative energy resources available are classified into non-renewable energy resources such as natural gas and coal; and renewable energy resources such as geothermal, biomass, solar energy, wind energy, ocean thermal energy conversion (OTEC), etc. Natural gas is one of the potential non-renewable energy resources available in Indonesia abundantly. The total potential reserves in Indonesia is estimated about 109.1 TSCF, which is including proven reserve of 80.2 TSCF. By the estimated production level of 2.0 TSCF per year for the fiscal year 1993/1994, these proven reserves can be still produced for 30 years more. Besides the reserves is available abundantly, the other advantage in developing natural gas for domestic consumption is a 'clean energy' rather than other fossil fuels. So that, it should be promoted to support the energy diversification and the clean environment policies. In the other side, electricity sector has a bigger opportunity than other sectors in supporting the energy diversification policy. There are several kinds of power generating plant which utilize various types of primary energy such as oil, gas, coal, geothermal, and hydro. Nevertheless, until this moment the utilization of natural gas in the electricity sector is still low of 15 percent. Recently, the growth of electricity demand in Indonesia is very high, especially in the Java-Bali grid system. There is a wide chance for natural gas to improve its role in electricity sector, and there is an economic variable which will determine the development of natural gas reserve, that is natural gas price itself. 4 refs., 2 figs., 4 tabs

Liquid natural gas occupies an increasing position in the energy mix of the USA

2002-01-01

Although the profitability of using liquid natural gas (LNG) depends on the fluctuations of the gas price, LNG will play an increasing role in the ''energy mix'' of the USA. The amount of LNG imported by the USA rose by 175% from 1998 to 2001. There are at present four receiving stations for LNG in the USA and they will probably be extended. Plans to build gas-powered power stations in California will increase the demand for natural gas in the coming years. Several companies have announced their desire to build receiving stations for LNG. There is, however, some opposition from environmentalists

Natural gas is more than gas power plants

International Nuclear Information System (INIS)

Lind, Oddvar

Through the Statpipe gas line at Karmoey, Norway supplies 20% of the natural gas on the European market. The pipeline is 'leaking' a little bit of gas to the local communities at Karmoey and Haugesund. These communities have replaced 65% of their oil consumption with natural gas, which is a fine contribution to a better environment. The supplier of the natural gas, Gasnor ASA in this case, claims an energy efficiency of 90% at the end user because the gas burns directly and the loss in the pipeline is minimal. The efficiency of natural gas utilisation is twice that of the planned gas power stations in West-Norway, subtracting the losses in the electrical network. Gasnor ASA competes with oil suppliers and, if necessary, with electric utilities. The county hospital at Haugesund is quoted as an example. The hospital has two large boilers with dual fuel burners. They have been using natural gas since 1998 because it was worth while both economically and environmentally. The use of natural gas in the transport sector would be very important, but the necessary infrastructure is very little developed. For instance, five diesel-powered ferries on the Boknafjord emit as much NOx as the planned gas power plant at Kaarstoe

Full Text Available Hydrates of the natural gas in the lithosphere are a very important potential source of energy that will be probably used in the coming decades. It seems as promising accumulation of the standard gas to form hydrates synthetically, stored, and disengage him when is peak demand. Storage of natural gas or biomethane in hydrates is advantageous not only in terms of storage capacity, but also from the aspect of safety storage hydrates. The gas stored in such form may occurs at relatively high temperatures and low pressures in comparison to other Technologies of gas- storage. In one cubic meter of hydrate can be stored up to 150 m3 of natural gas, depending on the conditions of thermobaric hydrate generation. This article discusses the design of the facility for the continuous generation of hydrates of natural gas measurement methodology and optimal conditions for their generation.

Economic Impacts of Increased U.S. Exports of Natural Gas: An Energy System Perspective

Kemal Sarıca

Full Text Available With the recent shale gas boom, the U.S. is expected to have very large natural gas resources. In this respect, the key question is would it be better to rely completely on free market resource allocations which would lead to large exports of natural gas or to limit natural gas exports so that more could be used in the U.S.. After accounting for the cost of liquefying the natural gas and shipping it to foreign markets, the current price difference leaves room for considerable profit to producers from exports. In addition, there is a large domestic demand for natural gas from various sectors such as electricity generation, industrial applications, and the transportation sector etc. A hybrid modeling approach has been carried out using our version of the well-known MARket ALlocation (MARKAL-Macro model to keep bottom-up model richness with macro effects to incorporate price and gross domestic product (GDP feedbacks. One of the conclusion of this study is that permitting higher natural gas export levels leads to a small reduction in GDP (0.04%–0.17%. Higher exports also increases U.S. greenhouse gas (GHG emissions and electricity prices (1.1%–7.2%. We also evaluate the impacts of natural gas exports in the presence of a Clean Energy Standard (CES for electricity. In this case, the GDP impacts are similar, but the electricity and transport sector impacts are different.

Natural gas in Latin America

International Nuclear Information System (INIS)

1997-01-01

Despite having proven reserves equal to that of North America, natural gas has traditionally played a minor role in the energy policies of Latin American countries, being considered secondary to oil. There has, therefore, been a neglect of the sector with a resultant lack of an adequate infrastructure throughout the region, perhaps with the exception of Argentina. However, with a massive increase in energy demand, growing concerns with environmental matters and a need to reduce the massive pollution levels in major cities in the region, natural gas is forecast to play a much greater role in Latin America's energy profile, with final consumption forecast to rise at 5.4% per annum for the next 15 years. This book assesses both the development of the use of natural gas in the power industrial sector and proposals for its growth into the residential, commercial and transport sectors. It analyses the significant investment required and the governments' need to turn to the private sector for investment and innovation. Natural Gas in Latin America analyses the possibilities and pitfalls of investing in the sector and describes the key trends and issues. It analyses all aspects of the gas industry from exploration and production to transportation and distribution to end users. (Author)

Highlights: • Low-temperature processes for of high CO_2 content natural gas have been modelled. • Energy and exergy analyses have been performed. • The Dual Pressure distillation scheme has the best thermodynamic performances. • There is a synergy between cryogenic natural gas purification and LNG production. - Abstract: Due to the rapid increase of the World’s primary energy demand of the last decades, low-temperature processes for the purification of natural gas streams with high carbon dioxide content has gained interest, since they allow to make profitable exploitation of low-quality gas reserves. Low temperature purification processes allow the direct production of a methane stream at high purity and at low-temperature, suitable conditions for the direct synergistic integration with natural gas cryogenic liquefaction processes, while CO_2 is obtained in liquid phase and under pressure. In this way, it can be pumped for transportation, avoiding significant compression costs as for classical CO_2 capture units (where carbon dioxide is discharged in gas phase and at atmospheric pressure), and further uses such as Enhanced Oil Recovery (EOR) or underground storage. In this paper, the three most common natural gas low-temperature purification techniques have been modelled and their performances have been evaluated through energy and exergy analyses. Specifically, the dual pressure low-temperature distillation process, the anti-sublimation process and a hybrid configuration have been considered. It is found that the dual pressure low-temperature distillation scheme reach the highest thermodynamic performances, resulting in the best values of exergy efficiency and equivalent methane requirements with respect to the other configurations. This is mainly due to the distributed temperature profile along a distillation column, resulting in a less irreversible heat exchanging process.

A series of overhead viewgraphs accompanied this presentation which focused on various aspects of the natural gas industry in Mexico. Some of the viewgraphs depicted statistics from 1998 regarding natural gas throughput from various companies in North America, natural gas reserves around the world, and natural gas reserves in Mexico. Other viewgraphs depicted associated and non-associated natural gas production from 1988 to 1998 in million cubic feet per day. The Burgos Basin and the Cantarell Basin gas production from 1997 to 2004 was also depicted. Other viewgraphs were entitled: (1) gas processing infrastructure for 1999, (2) cryogenic plant at Cd. PEMEX, (3) average annual growth of dry natural gas production for 1997-2004 is estimated at 5.2 per cent, (4) gas flows for December 1998, (5) PGPB- interconnect points, (6) U.S. Mexico gas trade for 1994-1998, (7) PGPB's interconnect projects with U.S., and (8) natural gas storage areas. Technological innovations in the industry include more efficient gas turbines which allow for cogeneration, heat recovery steam generators which reduce pollutant emissions by 21 per cent, cold boxes which increase heat transfer efficiency, and lateral reboilers which reduce energy consumption and total costs. A pie chart depicting natural gas demand by sector shows that natural gas for power generation will increase from 16 per cent in 1997 to 31 per cent in 2004. The opportunities for cogeneration projects were also reviewed. The Comision Federal de Electricidad and independent power producers represent the largest opportunity. The 1997-2001 investment program proposes an 85 per cent sulphur dioxide emission reduction compared to 1997 levels. This presentation also noted that during the 1998-2001 period, total ethane production will grow by 58 tbd. 31 figs

Turkey's natural gas necessity, consumption and future perspectives

Turkey is an important candidate to be the 'energy corridor' in the transmission of the abundant oil and natural gas resources of the Middle East and Middle Asia countries to the Western market. Furthermore, Turkey is planning to increase its oil and gas pipeline infrastructure to accommodate its increased energy consumption. Naturally, Turkish natural gas usage is projected to increase remarkably in coming years, with the prime consumers, expected to be industry and power plants. Energy demand of Turkey is growing by 8% annually, one of the highest rates in the world. In addition, natural gas consumption is the fastest growing primary energy source in Turkey. Gas sales started at 0.5 bcm (billion cubic meters), in 1987 and reached approximately 22 bcm in 2003. This article deals with energy policies and natural gas consumption of Turkey. Besides modernization of present lines and realization of capacity increase, new lines will also be needed. In this context, Turkey, due to its geographical location is, in an important position to vary European supply. Therefore, Turkey's role as a transitory area gains importance

Pakistan is an energy deficient country and heavily depends on imported energy. Natural gas is a dominating source of commercial energy in the country. This paper presents the natural gas consumption trends and future demand projections for Pakistan. The paper also investigates the potential utilization options of natural gas in the country. The study indicates that the natural gas consumption in the country increased rapidly at an average growth rate of about 6.8% per annum during the last three decades. Currently, natural gas contributes about 44.2% of the primary commercial energy supply in the country. Power, Fertilizer, General industry and Domestic sectors are the major consumers of gas in the country. The paper concludes the natural gas demand in the country is projected to increase to about 34-64 MTOE (Million Tonnes of Oil Equivalent) by the year 2018. Enhancement in the indigenous exploration and modulation of gas and import of gas from central Asian Sates is essential for meeting the growing gas demand, protecting the environment and increasing the economic independence in the country.

The exchange of experience with experts engaged in the US gas supply industry has shown that natural gas can be supplied there at a much lower price than in West Germany and that for this reason the price is not the main incentive to save energy. The low prices, which apply also to other forms of energy although not to the same extent, are a consequence of the energy policy pursued by the US government. The representatives of the gas supply industry are not in favour of this policy and attenpts have been made for some considerable time to effect a change in policy. As long as these attempts are not attended with success, the US gas supply industry is trying to achieve its aim by pointing out that natural gas is a national resource and that additional supplies will become available provided that present users adopt energy saving measures. The gas supply industry cooperates closely with the appliance manufacturers and retailers. Joint efforts have been made to help users reduce their energy bills by employing appliances that require less gas and by acquainting them with methods devised for making proper use of energy. The gas supply industry is further strongly interested in coal as a source of energy for largely substituting SNG for natural Gas.

Natural Gas Transmission and Distribution Model of the National Energy Modeling System. Volume 1

1998-01-01

The Natural Gas Transmission and Distribution Model (NGTDM) is the component of the National Energy Modeling System (NEMS) that is used to represent the domestic natural gas transmission and distribution system. The NGTDM is the model within the NEMS that represents the transmission, distribution, and pricing of natural gas. The model also includes representations of the end-use demand for natural gas, the production of domestic natural gas, and the availability of natural gas traded on the international market based on information received from other NEMS models. The NGTDM determines the flow of natural gas in an aggregate, domestic pipeline network, connecting domestic and foreign supply regions with 12 demand regions. The purpose of this report is to provide a reference document for model analysts, users, and the public that defines the objectives of the model, describes its basic design, provides detail on the methodology employed, and describes the model inputs, outputs, and key assumptions. Subsequent chapters of this report provide: an overview of NGTDM; a description of the interface between the NEMS and NGTDM; an overview of the solution methodology of the NGTDM; the solution methodology for the Annual Flow Module; the solution methodology for the Distributor Tariff Module; the solution methodology for the Capacity Expansion Module; the solution methodology for the Pipeline Tariff Module; and a description of model assumptions, inputs, and outputs.

Trading in LNG and natural gas

International Nuclear Information System (INIS)

1992-01-01

We have examined the market for natural gas from a number of viewpoints, starting with the role of natural gas in the global energy market where its 20% share of primary energy demand has been captured in the space of almost as many years. In discussion regional energy markets we cover the disparities between supply and demand which give rise to trade by pipeline, and by sea in the form of liquefied natural gas (LNG). Both have in fact increased steadily in recent years, yet even in 1991, only 12-15% of total gas production was traded across international boundaries, whereas for oil it was closer to 40%. For the moment pipeline trade remains heavily concentrated in Europe and North America, and it is in the LNG sector where the spread of projects, both existing and planned, is more global in nature. We examine the development of LNG trades and the implications for shipping. Finally, we look at transportation costs, which are likely to be an important component in the viability of many of the natural gas export schemes now under review. There is good reason to be ''bullish'' about parts of the natural gas industry but this Report suggests that there are areas of concern which could impinge on the development of the market in the 1990s.

The Maritimes natural gas market overview and assessment : an energy market assessment

International Nuclear Information System (INIS)

2003-06-01

The National Energy Board continually monitors the supply of all energy commodities in Canada along with the demand for Canadian energy commodities in domestic and export markets. This report provides an assessment of the functioning of the natural gas market in the Maritimes and discusses several issues facing the market. The focus of the report is on the existing markets served by the Maritimes and Northeast Pipeline (M and NP) in Nova Scotia and New Brunswick. It also includes Prince Edward Island, another Maritime market that may be served by the pipeline before the end of the decade. Since the initiation of the Sable Offshore Energy (SOE) Project more than 3 years ago, pipeline facilities have been built off the mainline M and NP system to serve Halifax and Point Tupper in Nova Scotia, and Saint John, Moncton, and St. George in New Brunswick. Enbridge Gas New Brunswick has built distribution facilities in Fredericton and Oromocto, New Brunswick to serve large industrial, commercial and residential consumers. A distribution system has not been set up for residential or commercial customers in Nova Scotia. Approximately 20 per cent of the Scotian production is being consumed in the Maritimes, while 80 per cent of the gas produced from the SOE Project is being exported to the United States. Despite the high export, the Board is satisfied that the market is working to the benefit of Canadians because energy users in the Maritimes already have access to a variety of fuels at competitive prices. The Maritimes also benefited from the development of the natural gas industry and the export market has provided a large anchor market necessary for the development of offshore reserves. Domestic demand has also grown due to a pipeline system policy that has maintained low transportation rates to domestic users. The challenges facing the Maritimes gas market include the fact than many of the markets in the Maritimes are small, thereby reducing the economics of serving these

Institutional change in European natural gas markets and implications for energy security: Lessons from the German case

International Nuclear Information System (INIS)

Westphal, Kirsten

2014-01-01

This article focuses on institutional change in the German gas market driven by EU internal market and climate policies. It argues that institutional change has functional externalities for energy security. The German gas market provides a useful case study, as Germany is the biggest continental gas market, a major hub and transport country which has largely privatised, unbundled and separated its natural gas undertakings. Transition is ongoing, tending towards an internal market. Inter/national natural gas economics is in flux. Institutional evolution has repercussions for corporate and market structures, the operating of the system and the realization of transactions. Changes in the institutional framework crucially affect energy security, which is often associated with institutional stability. On the basis of this case study, it is argued herein that the security of natural gas supplies should be reexamined in the context of the developments described above, since overall the institutional changes in natural gas security lag behind the EU’s internal natural gas market development. - Highlights: • EU natural gas market regulation primarily aims to establish competitive markets. • German/EU regulatory approach has externalities for supply security. • Institutional changes and breaks with path dependencies take place in Germany/the EU. • Institutional change results in increasing uncertainty and complexity. • Subsequent change in perceptions and expectations may destabilise trade relations

Natural Gas Regulation

The regulation of Natural Gas. Natural gas Regulation clarifies and consolidates the legal and institutional framework for development of the industry through six principal elements: 1) Establishment of a vision of the industry. 2) Development of regulatory objectives. 3) Determination of relationships among industry participants. 4) Clear specification of the role of PEMEX in the industry. 5) Definition of the functions of the Regulatory authority. 6) Creation of a transition regime. In parallel with the development of the substantive legal framework, the law of the Comision Reguladora de Energia (CRE) was also enacted by Congress in October 1995 to strength the institutional framework and implement the legal changes. This law defines the CRE as an agency of the Energy Ministry with technical, operational, and budgetary autonomy, and responsibility for implementing natural gas industry regulation. (Author)

Studies have shown that the demand for crude oil exceeds supply and other energy sources are needed to met the shortfall. Natural gas and coal are the only 2 current energy sources that have the global capacity to, by themselves, address increased energy demand in a timely manner. Both these resources have been used primarily for power generation and heating. This paper discussed the transition that will likely occur in which natural gas and coal will be used increasingly as transportation fuels. It presented data comparing the environmental impact of using methane versus coal and proposed natural gas as the future green fuel. A strengths, weaknesses, opportunities and threats (SWOT) analysis was conducted to obtain a better understanding of the current Canadian natural gas market. The strengths include recent discoveries in the Horn River Basin and the Montney plays in British Columbia which are expected to triple natural gas production within the next decade. The weaknesses include an oversupply of gas compared to current demand; gas prices are currently in a range that are barely economic for many shale plays; and Canadian gas is disadvantaged for sales in the United States by additional pipeline transportation costs. The opportunities include global export opportunities of liquefied natural gas (LNG) through the proposed Kitimat LNG export facility and others off the west coast of Canada. The threat facing natural gas development is the strong competition for market share with coal. However, emissions data and energy efficiencies provide evidence to support the choice to use natural gas. 5 refs., 2 tabs., 26 figs.

The threat facing natural gas development is the strong competition for market share with coal. However, emissions data and energy efficiencies provide evidence to support the choice to use natural gas. 5 refs., 2 tabs., 26 figs.

The natural gas industry in Portugal

International Nuclear Information System (INIS)

Kheloufi, S.

2004-01-01

This article makes a synthesis of the evolution of the natural gas sector in Portugal since the end of the 1990's. The aim of the energy policy of Portugal was the creation of a liberalized energy market capable to ensure the security of the energy supplies and to encourage the energy efficiency in order to reduce the environmental impact. The success of the introduction of natural gas in Portugal perfectly fulfills these goals. Since 1997, the natural gas consumption has increased significantly. The start-up of the methane terminal of Sines allows the diversification of the supply sources and contributes to the growth of the offer. The opening of the market is under development. It will allow the main consumers to select their supplier among those present on the Portuguese market. GALP company should keep its leader position and its daughter company 'Gas du Portugal' should reach 300 MW of power generation capacities by 2005 with the development of multi-energy services. The creation of an Iberian energy market between Spain and Portugal should speed up in 2004 leading to deep modifications in the energy sector of southern Europe. (J.S.)

Explaining experience curves for new energy technologies. A case study of liquefied natural gas

International Nuclear Information System (INIS)

Greaker, Mads; Lund Sagen, Eirik

2008-01-01

Many new energy technologies seem to experience a fall in unit price as they mature. In this paper we study the unit price of liquefying natural gas in order to make it transportable by ship to gas power installations all over the world. Our point of departure is the experience curve approach, however unlike many other studies of new energy technologies, we also seek to account for autonomous technological change, scale effects and the effects of upstream competition among technology suppliers. To our surprise we find that upstream competition is by far the most important factor contributing to the fall in unit price. With respect to the natural gas business, this may have implications for the future development in prices as the effect of increased upstream competition is temporary and likely to weaken a lot sooner than effects from learning and technological change. Another more general policy implication, is that while promoting new energy technologies, governments must not forget to pay attention to competition policy. (author)

The price of natural gas

International Nuclear Information System (INIS)

Bakhtiari, A.M.S.

2001-01-01

Natural gas used to be a relatively cheap primary energy source, always at a discount to crude oil (on a comparative British thermal unit basis). It gradually evolved into a major resource during the 20th century - reaching a 24 per cent share of global primary energy in 1999. In the year 2000, natural gas prices in the USA rose to unheard-of highs of 10/million US dollars Btu, ushering in a new era, with natural gas at a 120 per cent premium to crude oil. This clearly was a watershed for gas, somehow similar to the 1973-74 watershed for oil prices. And similarly, any return to the status quo-ante looks rather improbable, although a number of experts (alongside the International Energy Agency) still believe the 2000 price 'spike' to have been ''only transitory''. The consequences of higher gas prices (at a level equal to crude oil prices on a Btu basis) will be multifaceted and momentous, altering habits and uses in downstream industries and economic sectors, as well as providing added income for major gas-exporters, such as Russia, Canada and Algeria. Another potential consequence of the 2000 watershed might be to propel US standard prices (such as the 'Henry Hub' spot) to international status and gas price-setter, as the 'WTI spot' became an 'international benchmark' for crude oils in the post-1993 era. For the time being, the equality of gas and oil prices has become the new norm; but, in the longer term, a discount of crude oil relative to natural gas might be envisaged, as the latter is a cleaner fuel and emits less carbon dioxide when used.

Natural-gas supply-and-demand problems

International Nuclear Information System (INIS)

Hatamian, H.

1998-01-01

World natural-gas consumption quadrupled in the 30 years from 1966 to 1996, and natural gas now provides 22% of the total world energy demand. The security of natural-gas supply is paramount and rests with the suppliers and the consumers. This paper gives an overview of world natural-gas supply and demand and examines the main supply problems. The most important nonpredictable variables in natural-gas supply are worldwide gas price and political stability, particularly in regions with high reserves. Other important considerations are the cost of development/processing and the transport of natural gas to market, which can be difficult to maintain if pipelines pass through areas of political instability. Another problem is that many countries lack the infrastructure and capital for effective development of their natural-gas industry. Unlike oil, the cost of transportation of natural gas is very high, and, surprisingly, only approximately 16% of the total world production currently is traded internationally

Driving on natural gas (CNG, Compressed Natural Gas) has been the talk of the industry for many years now. Although the benefits of natural gas as an engine fuel have become well-known, this phenomenon does not seem to gain momentum in the Netherlands. Over the last few months, however, the attitude towards CNG seems to be changing. Energy companies are increasingly engaged in commercial activities, e.g. selling natural gas at petrol stations, an increasing number of car manufacturers are delivering natural gas vehicles ex-works, and recently the NGV (Natural Gas Vehicles) Holland platform was set up for the unequivocal marketing of natural gas as an engine fuel

Preliminary formation analysis for compressed air energy storage in depleted natural gas reservoirs :

Energy Technology Data Exchange (ETDEWEB)

Gardner, William Payton

2013-06-01

The purpose of this study is to develop an engineering and operational understanding of CAES performance for a depleted natural gas reservoir by evaluation of relative permeability effects of air, water and natural gas in depleted natural gas reservoirs as a reservoir is initially depleted, an air bubble is created, and as air is initially cycled. The composition of produced gases will be evaluated as the three phase flow of methane, nitrogen and brine are modeled. The effects of a methane gas phase on the relative permeability of air in a formation are investigated and the composition of the produced fluid, which consists primarily of the amount of natural gas in the produced air are determined. Simulations of compressed air energy storage (CAES) in depleted natural gas reservoirs were carried out to assess the effect of formation permeability on the design of a simple CAES system. The injection of N2 (as a proxy to air), and the extraction of the resulting gas mixture in a depleted natural gas reservoir were modeled using the TOUGH2 reservoir simulator with the EOS7c equation of state. The optimal borehole spacing was determined as a function of the formation scale intrinsic permeability. Natural gas reservoir results are similar to those for an aquifer. Borehole spacing is dependent upon the intrinsic permeability of the formation. Higher permeability allows increased injection and extraction rates which is equivalent to more power per borehole for a given screen length. The number of boreholes per 100 MW for a given intrinsic permeability in a depleted natural gas reservoir is essentially identical to that determined for a simple aquifer of identical properties. During bubble formation methane is displaced and a sharp N2methane boundary is formed with an almost pure N2 gas phase in the bubble near the borehole. During cycling mixing of methane and air occurs along the boundary as the air bubble boundary moves. The extracted gas mixture changes as a

Accounting for fuel price risk: Using forward natural gas prices instead of gas price forecasts to compare renewable to natural gas-fired generation

Energy Technology Data Exchange (ETDEWEB)

Bolinger, Mark; Wiser, Ryan; Golove, William

2003-08-13

Against the backdrop of increasingly volatile natural gas prices, renewable energy resources, which by their nature are immune to natural gas fuel price risk, provide a real economic benefit. Unlike many contracts for natural gas-fired generation, renewable generation is typically sold under fixed-price contracts. Assuming that electricity consumers value long-term price stability, a utility or other retail electricity supplier that is looking to expand its resource portfolio (or a policymaker interested in evaluating different resource options) should therefore compare the cost of fixed-price renewable generation to the hedged or guaranteed cost of new natural gas-fired generation, rather than to projected costs based on uncertain gas price forecasts. To do otherwise would be to compare apples to oranges: by their nature, renewable resources carry no natural gas fuel price risk, and if the market values that attribute, then the most appropriate comparison is to the hedged cost of natural gas-fired generation. Nonetheless, utilities and others often compare the costs of renewable to gas-fired generation using as their fuel price input long-term gas price forecasts that are inherently uncertain, rather than long-term natural gas forward prices that can actually be locked in. This practice raises the critical question of how these two price streams compare. If they are similar, then one might conclude that forecast-based modeling and planning exercises are in fact approximating an apples-to-apples comparison, and no further consideration is necessary. If, however, natural gas forward prices systematically differ from price forecasts, then the use of such forecasts in planning and modeling exercises will yield results that are biased in favor of either renewable (if forwards < forecasts) or natural gas-fired generation (if forwards > forecasts). In this report we compare the cost of hedging natural gas price risk through traditional gas-based hedging instruments (e

Canadian natural gas market: dynamics and pricing

International Nuclear Information System (INIS)

2000-01-01

This publication by the National Energy Board is part of a continuing program of assessing applications for long-term natural gas export licences. The market-based procedure used by the Board is based on the premise that the marketplace will generally operate in a way that will ensure that Canadian requirements for natural gas will be met at fair market prices. The market--based procedure consists of a public hearing and a monitoring component. The monitoring component involves the on-going assessment of Canadian energy markets to provide analyses of major energy commodities on either an individual or integrated commodity basis. This report is the result of the most recent assessment . It identifies factors that affect natural gas prices and describes the functioning of regional markets in Canada. It provides an overview of the energy demand, including recent trends, reviews the North American gas supply and markets, the natural gas pricing dynamics in Canada, and a regional analysis of markets, prices and dynamics in British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, Quebec and the Atlantic provinces. In general, demand growth outstripped growth in supply, but natural gas producers throughout North America have been responding to the current high price environment with aggressive drilling programs. The Board anticipates that in time, there will be a supply and demand response and accompanying relief in natural gas prices. A review of the annual weighted average border price paid for Alberta gas indicates that domestic gas users paid less than export customers until 1998, at which point the two prices converged, suggesting that Canadians have had access to natural gas at prices no less favourable than export customers. The influence of electronic trading systems such as NYMEX and AECO-C/NIT have had significant impact on the pricing of natural gas. These systems, by providing timely information to market participants. enables them to manage price

To fully exert the important role of natural gas in building a modern energy security system in China: An understanding of China's National l3th Five-Year Plan for Natural Gas Development

2017-07-01

Full Text Available Along with the introduction of 13th Five-Year Plans in succession for natural gas development programmed by governments at all levels and much more attention paid to haze governance by relevant departments, natural gas, as one of the major energy sources, has ushered in a strategic opportunity era. In view of this, based upon China's National 13th Five-Year Plan for Natural Gas Development formulated by the National Development and Reform Commission, the developing trend of natural gas sector was predicted in the period of 13th Five-Year Plan in terms of supply side, demand side, pricing system, infrastructure construction, etc. and some feasible proposals were made on the whole industrial chain. In terms of the supply side, natural gas will be of availability, accessibility, assurance, affordability, and accountability in the production and supply chains. In terms of the demand side, air pollution treatment will indirectly stimulate gas consumption increase. Gas power generation will become the dominant. Natural gas as a transportation fuel will bring a good new opportunity. Thus it is believed that as the present natural gas development is restricted by both gas pricing system and infrastructure construction, further reform should be strengthened to break the barriers of systems and mechanisms; and that due to many uncertainties in the natural gas market, the decisive role of market in the resource allocation should be fully exerted to ensure the main force of natural gas in building a dependable energy strategic system in present and future China.

Natural gas demand prospects in Korea

Kwon, Young-Jin [Korea Electric Power Corp. (KEPCO), Seoul (Korea, Republic of)

1997-06-01

Korea s natural gas demand has increase enormously since 1986. Natural gas demand in Korea will approach to 29 million tonnes by the year 2010, from little over 9 million tonnes in 1996. This rapid expansion of natural gas demand is largely due to regulations for environmental protection by the government as well as consumers preference to natural gas over other sources of energy. Especially industrial use of gas will expand faster than other use of gas, although it will not be as high as that in European and North America countries. To meet the enormous increase in demand, Korean government and Korea Gas Corporation (KOGAS) are undertaking expansion of capacities of natural gas supply facilities, and are seeking diversification of import sources, including participation in major gas projects, to secure the import sources on more reliable grounds.

Natural gas is the major indigenous source of energy in Bangladesh and accounts for almost one-half of all primary energy used in the country. Per capita and total energy use in Bangladesh is still very small, and it is important to understand how energy, and natural gas demand will evolve in the future. We develop a dynamic econometric model to understand the natural gas demand in Bangladesh, both in the national level, and also for a few sub-sectors. Our demand model shows large long run income elasticity - around 1.5 - for aggregate demand for natural gas. Forecasts into the future also show a larger demand in the future than predicted by various national and multilateral organizations. Even then, it is possible that our forecasts could still be at the lower end of the future energy demand. Price response was statistically not different from zero, indicating that prices are possibly too low and that there is a large suppressed demand for natural gas in the country. - Highlights: → Natural gas demand is modeled using dynamic econometric methods, first of its kind in Bangladesh. → Income elasticity for aggregate natural gas demand in Bangladesh is large-around 1.5. → Demand is price insensitive, indicating too low prices and/or presence of large suppressed demand. → Demand forecasts reveal large divergence from previous estimates, which is important for planning. → Attempts to model demand for end-use sectors were successful only for the industrial sector.

Nordic cooperation within natural gas research is discussed. A reorganization of this cooperation has recently taken place. It is explained that common Nordic resources are now to be concentrated within 7 areas, one of which is the area of energy/industrial policies, regional policies and agriculture and forestry, all under the common heading of ''Economy''. The plan of activities within this area includes international cooperation within the European Communities, the European Energy Charter, the International Energy Agency and will involve the energy policy situation in eastern Europe and the Baltic countries, the electric power and natural gas markets in the northern countries, energy related environmental questions and Nordic energy research cooperation. Nordic research activities constitute 2% of research resources within the OECD. The basis for Nordic research cooperation (for example a common cultural background) is described, and suggestions are made as to how it should be administrated. The Nordic energy research programme for 1991-1994 embodies bioenergy and the environment, fuel cells, energy and the society, solid fuels, district heating and petroleum technology. The status report for the nordic gas market, which represents the Nordic gas companies' evaluation of the Nordic gas market, is summarized, and Nordic research activities related to gas utilization are shortly commented upon.

Pricing the (European) option to switch between two energy sources: An application to crude oil and natural gas

International Nuclear Information System (INIS)

Gatfaoui, Hayette

2015-01-01

We consider a firm, which can choose between crude oil and natural gas to run its business. The firm selects the energy source, which minimizes its energy or production costs at a given time horizon. Assuming the energy strategy to be established over a fixed time window, the energy choice decision will be made at a given future date T. In this light, the firm's energy cost can be considered as a long position in a risk-free bond by an amount of the terminal oil price, and a short position in a European put option to switch from oil to gas by an amount of the terminal oil price too. As a result, the option to switch from crude oil to natural gas allows for establishing a hedging strategy with respect to energy costs. Modeling stochastically the underlying asset of the European put, we propose a valuation formula of the option to switch and calibrate the pricing formula to empirical data on a daily basis. Hence, our innovative framework handles widely the hedge against the price increase of any given energy source versus the price of another competing energy source (i.e. minimizing energy costs). Moreover, we provide a price for the cost-reducing effect of the capability to switch from one energy source to another one (i.e. hedging energy price risk). - Highlights: • We consider a firm, which chooses either crude oil or natural gas as an energy source. • The capability to switch offers the firm a hedge against energy commodity price risk. • A European put option prices the ability to switch from crude oil to natural gas. • The capability to switch between two energy sources reduces the firm's energy costs. • The discount illustrates the efficiency of the energy management policy (e.g. timing).

Natural Gas Container Transportation: the Alternative Way to Solve the World’s Energy Transportation Problems

Full Text Available The container gas transportation for low and medium level consumers as an alternative to pipelines is considered. The options for gas supply schemes, based on road and rail transport are given. The advantages and disadvantages of both types of gas transporting are described, the areas of their effective using are separated in the article. Promising implementations of technology in environment of economic crisis and also considering world trends of energy development are presented. The most advanced organization of compressed gas condensate transportation of unprepared gas fields in large diameter universal cylindrical balloons (up to 1000 mm are reasoned. The problem of compressed gas sea transportation are well disclosed, but the alternative ways of gas transportation by land are not investigated enough. Compressed Natural Gas (CNG Technology - is new promising technology for natural gas transportation by specially designed vessels – CNG-vessels. The feature of this technology is that natural gas can be downloaded directly near gas deposits and unloaded - directly into the customer's network. This eliminates significant capital investments in underwater pipelining or gas liquefaction plants. The main objects of investment are CNG-vessels themselves. The most attractive places for implementation of CNG-technology are sea (offshore natural gas deposits. Numerous international experts estimate the natural gas transportation by CNG-vessels in 1.5-2.0 times more cost-beneficial in comparison with offshore pipelines transportation, or in comparison with LNG (Liquefied Natural Gas shipping with natural gas transportation volume between 0.5 and 4.0 billion cubic meters per year on the route from 250 to 2,500 sea miles.

Ocelík, Petr; Osička, Jan

2014-01-01

The advent of unconventional resources of natural gas has altered the order on global as well as continental gas markets. With rising liquidity, the position of established dominant suppliers is eroding. We focus on the initial response of Russia, the leading supplier of natural gas to Europe, to the new situation, building the research on unit-level constructivism and discourse analysis. We use frame analysis to reveal what image of unconventional resources was constructed in Russian foreign energy policy discourse (FEPD) in the period between 2009 and 2011, when the “unconventional revolution” did not yet have any sharp contours. We conclude that in Russian FEPD the unconventionals are considered as a distinctive and inferior source of energy compared to conventional natural gas. Emphasis is put on their economic irrationality and environmental hazards. The bottom line of the discourse is the idea that there is a choice between conventional and unconventional sources, with this choice being framed as one between good and bad, or right and wrong. - Highlights: • We examine the image of “unconventional gas” in Russian foreign energy policy discourse. • Two main frames (reliable supplier and triumphant natural gas) were identified. • Two main argumentation schemes (economic and environmental) were identified. • The “unconventional gas” is defined as a mistaken and inferior source of energy

Natural gas prices

Since the 1970s, many electric utilities and industrial boiler fuel users have invested in dual fuel use capability which has allowed them to choose between natural gas, residual fuel oil, and in some instances, coal as boiler fuels. The immediate reason for this investment was the need for security of supply. Wellhead regulation of natural gas prices had resulted in shortages during the 1970s. Because many industrial users were given lowest priority in pipeline curtailments, these shortages affected most severely boiler fuel consumption of natural gas. In addition, foreign supply disruptions during the 1970s called into question the ready availability of oil. Many boiler fuel users of oil responded by increasing their ability to diversify to other sources of energy. Even though widespread investment in dual fuel use capability by boiler fuel users was initially motivated by a need for security of supply, perhaps the most important consequence of this investment was greater substitutability between natural gas and resid and a more competitive boiler fuel market. By the early 1980s, most boiler fuel users were able to switch from one fuel to another and often did for savings measured in pennies per MMBtu. Boiler fuel consumption became the marginal use of both natural gas and resid, with coal a looming threat on the horizon to both fuels

An overview of the Bulgarian natural gas industry is presented. The starting point was the discovery of the indigenous Chiren gas-field in 1967. The first agreement with the ex-USSR for supply of natural gas and construction of main pipelines was signed in 1968. The state gas company BULGARGAZ is responsible for transportation, storage, distribution, processing and marketing of the gas to over 150 industrial companies in the country, as well as for the transportation services to gas importers in neighboring Turkey. The GAZSTROJMONTAZH company accomplish the construction of the local and transit pipelines to Turkey and Greece, as well as of some objects in Iran, Syria, Ukraine and Germany. In the past 20 years, 87890 million m 3 natural gas from Russia are supplied and 846 million m 3 - from domestic sources. The share of natural gas in the overall energy balance is 13.6% for 1992. The restructuring and further development of gas industry require to take into account some factors as: security in supply; investments for technical assurance; pricing policy for natural gas; development of private business. Some administrative problems are also mentioned. 2 tabs., 1 fig

Improving efficiency and effectiveness in natural gas regulation : discussion paper

International Nuclear Information System (INIS)

Rounding, M.C.

2004-11-01

Energy market liberalization is a world trend that has prompted the deregulation of natural gas and electricity over the past twenty years in North America. The Ontario Energy Board and the National Energy Board are conducting public hearings on natural gas regulation in response to the request by Canadian energy industries for better regulatory streamlining. The following 5 issues regarding natural gas regulation in Canada have been examined: (1) system gas in a regulated market, (2) natural gas infrastructure investments and capital renewal, (3) improving efficiency in gas regulation, (4) expectations of performance-based regulation (PBR) in the natural gas industry, and (5) the debate whether further deregulation of the natural gas industry is beneficial. This paper discusses the impact that natural gas regulation has had on the efficiency and competitiveness of the industry and its affect on customers and other stakeholders. It focuses on the efficiency of the regulatory process and examines regulatory objectives, best practices and performance indicators. The factors that determine the efficiency of natural gas regulation include alternative regulatory models, structure of the regulatory agency, regulatory framework approaches, and outcomes for the natural gas industry. The relationship between the government and the regulator was also examined in terms of their abilities to implement policy. A comparative evaluation between energy regulators in Canada, the United States, Australia and the United Kingdom was presented. The balancing of short-term and long-term objectives for gas supply and planning issues was also addressed. 17 refs

Density functional theory was performed for thermodynamic predictions on natural gas, whose B3LYP/6-311++G(d,p), B3LYP/6-31+G(d), CBS-QB3, G3, and G4 methods were applied. Additionally, we carried out thermodynamic predictions using G3/G4 averaged. The calculations were performed for each major component of seven kinds of natural gas and to their respective air + natural gas mixtures at a thermal equilibrium between room temperature and the initial temperature of a combustion chamber during the injection stage. The following thermodynamic properties were obtained: internal energy, enthalpy, Gibbs free energy and entropy, which enabled us to investigate the thermal resistance of fuels. Also, we estimated an important parameter, namely, the specific heat ratio of each natural gas; this allowed us to compare the results with the empirical functions of these parameters, where the B3LYP/6-311++G(d,p) and G3/G4 methods showed better agreements. In addition, relevant information on the thermal and mechanic resistance of natural gases were investigated, as well as the standard thermodynamic properties for the combustion of natural gas. Thus, we show that density functional theory can be useful for predicting the thermodynamic properties of natural gas, enabling the production of more efficient compositions for the investigated fuels.

During the 1990's, natural gas was the energy source with the fastest rate of growth in the world energy balance. Nevertheless, recent evolutions of the energy context, in particular in terms of prices, have had a rather strong impact on the progress of the different energy sources penalizing gas a little. Beyond this competition between energies, which may increase, the medium-term perspectives of natural gas development is in keeping with an environment full of uncertainties. This article presents: the world supply and demand prospects for 2010-2015 (impact of high gas prices on other energy sources, occurrence of production constraints, political decisions of producing countries and world gas industry balance), trends on main markets (North America, Europe, Asia-Oceania), and international trade.

The role of various atmospheric pollutants in environmental changes and the global water cycle, carbon cycle, and energy balance is explained. The role of sulfur dioxide and nitrogen oxides in acid deposition is also outlined. The pollutants that contribute to environmental problems include nitrogen oxides and volatile organic compounds, carbon dioxide, and other greenhouse gases. The potential for natural gas utilization to mitigate some of these pollution problems is explored. Natural gas combustion emits less carbon dioxide and nitrogen oxides than combustion of other fossil fuel, and also does not produce sulfur dioxide, particulates, or volatile organics. Other pollution controlling opportunities offered by natural gas include the use of low-polluting burners, natural gas vehicles, and cogeneration systems. 18 figs., 4 tabs

Short-term natural gas consumption forecasting

Energy forecasting requirements for Slovenia's natural gas market were investigated along with the cycles of natural gas consumption. This paper presented a short-term natural gas forecasting approach where the daily, weekly and yearly gas consumption were analyzed and the information obtained was incorporated into the forecasting model for hourly forecasting for the next day. The natural gas market depends on forecasting in order to optimize the leasing of storage capacities. As such, natural gas distribution companies have an economic incentive to accurately forecast their future gas consumption. The authors proposed a forecasting model with the following properties: two submodels for the winter and summer seasons; input variables including past consumption data, weather data, weather forecasts and basic cycle indexes; and, a hierarchical forecasting structure in which a daily model was used as the basis, with the hourly forecast obtained by modeling the relative daily profile. This proposed method was illustrated by a forecasting example for Slovenia's natural gas market. 11 refs., 11 figs

This presentation provided a perspective of Arctic energy resource development and the impact that science and technology will have on the American National Energy Policy (NEP). The role of the NEP is to provide energy security for the United States by ensuring dependable, affordable and sustainable energy for the future. The United States Department of Energy (DOE) conducts a wide range of energy and research activities that contribute to energy efficiency advances that help meet rising energy demand and reduce pollution emissions. In May 2001, the NEP proposed 100 recommendations, of which half focus on energy efficiency and developing renewable energy sources. The Clean Coal Power Initiative is also based on technological innovation and focuses on a program called FutureGen to build and operate a zero emission coal-fired power plant to produce both electricity and hydrogen. These initiatives could result in major changes in America's energy scenario. The provisions of the Energy Bill in streamlining the regulatory process for the proposed Alaska gas pipeline were outlined. The 2004 Annual Energy Outlook for the United States indicates that a pipeline from the Mackenzie Delta to Alberta would be constructed first, followed by one from Alaska. The North Slope Alaska natural gas pipeline will likely be operational by 2018 and add 4.5 BCF per day to meet growing natural gas demand in the United States. The National Petroleum Council's report on America's long-term natural gas supply and demand situation claims that lower-48 and traditional Canadian natural gas basins will be able to supply 75 per cent of the U.S. demand by the year 2025. The remainder will be made up by Alaskan natural gas, liquefied natural gas (LNG) and gas from new sources in Canada such as coalbed methane, methane hydrates, and oil sands

Environmental regulations in Mexico could dramatically increase demand for natural gas in the following years. This increase could lead to gas price shocks and a counter-intuitive increase in carbon emissions. The effect would be accentuated if Mexico lacks the funds required to carry on with investments in gas development and processing capacity. With the use of a dynamic computer model, this study addresses responses of the Mexican oil and gas industries to perturbations such as: changes in regulatory and environmental policies; changes in institutional arrangements such as those arising from market liberalization; and lack of availability of investment funds. The study also assesses how regulatory policies can be designed to minimize the economic inefficiencies arising from the business cycle disruptions that some perturbations may cause. In addition, this study investigates how investment responses will shape the Mexican energy sector in the future, particularly with respect to both the relative importance of different fuels for power generation and heating purposes and the nature of competition in the Mexican natural gas market. Furthermore, this study explores the direct consequences of these responses on the level of carbon emissions. (Author)

Prospects for the natural gas supply in Europe

Bergmann, B.

An overview is given of the current significance of and future prospects for natural gas in Europe. Special attention is given to the impressive development of natural gas in the energy markets of Europe during the last 20 years, the development of demand for natural gas, the procurement situation, and political framework conditions. By virtue of the environmental and energy political dictates governing modern industrial societies, the European gas economy finds itself dealing in an excellent product whose share in the energy market will continue to grow. The decisive challenge lies in procuring additional quantities, which will largely have to come from outside the territory of the European Community. In order to succeed in this task the gas economies need an energy political framework that strengthens, and not weakens, their position in the Community. (orig./HSCH) [de

Administration of the natural gas shortage in the USA

Energy Technology Data Exchange (ETDEWEB)

Pluge, W [Koeln Univ. (Germany, F.R.). Inst. fuer Energiewirtschaft

1978-05-01

The natural gas deficit is basically a consequence of the price policy of the U.S. government which keeps the prices of natural gas transported from one state to another subject to a maximum-price regulation. In the course of this development, the U.S. natural gas market has been characterized by three different types of shortage since the early seventies. There are regional differences in the administration of the shortage. Compared to the alternatives the rationing plan of the Federal Energy Regulatory Commission (FERC) is the best solution from on overall economic point of view, but it is rather impracticable and hard to put through completely. Natural gas rationing in the USA did not prevent temporary production losses and unemployment due to shortage. If the maximum-price regulation policy for natural gas is continued, the supply deficit for this energy carrier will become even greater. If, as the National Energy Plan proposes, the maximum-price regulation for natural gas would also pertain to the intrastate market in the future, natural gas shortages would occur there, too.

Transit of Natural Gas. Monitoring Report on the Implementation of the Transit Provisions of the Energy Charter Treaty

International Nuclear Information System (INIS)

2007-03-01

Natural gas is transported over increasingly large distances from producers to consumers. Most of this transportation takes place by pipelines and often involves crossing multiple national borders. Recent events demonstrated that disputes over energy transit can quickly have multilateral implications for gas supply, demonstrating the need for a framework for reliable cross-border gas flows. The Energy Charter Treaty (ECT) provides a set of binding rules that cover the entire energy chain, including the terms to transport energy across various national jurisdictions. The transit provisions of the Treaty support the reliability of established flows and the creation of new transport capacity, thus contributing to the reliability of gas transit. The Energy Charter's Group on Trade and Transit monitors and assists in the implementation of the ECT and its instruments on trade and transit and suggests improvements of implementation. The present report monitors the implementation of the Energy Charter transit principles for natural gas by giving an analysis of its legislative and practical aspects in selected member countries of the ECT constituency

Natural gas and crude oil

Valais, M.R.

Two main development could gradually modify these traditional features of natural gas markets and prices. First, environmental pressures and the tightening of emission standards and of the quality specifications for fuels should work in favor of natural gas. Second the increasing distance of resources in relation to the major consuming zones should bring about a considerable development of international natural gas trade. International expansion should mark the development of the gas industry in the coming decades. This evolution will give natural gas an importance and a role appreciably closer to those of oil on the world energy scene. But it is obvious that such a development can come about only at the cost of considerable investments for which the economic viability is and will remain dependent on the level of the prices of natural gas as the inlet to its consuming markets. This paper attempts to answer the questions: Will these markets accept a new scale of value for gas in relation to other fossil fuels, including oil, which will take into account new environmental constraints and which will be able to fulfill the formidable financial needs of the gas industry in the coming decades?

Natural gas contracts in efficient portfolios

Energy Technology Data Exchange (ETDEWEB)

Sutherland, R.J.

1994-12-01

This report addresses the {open_quotes}contracts portfolio{close_quotes} issue of natural gas contracts in support of the Domestic Natural Gas and Oil Initiative (DGOI) published by the U.S. Department of Energy in 1994. The analysis is a result of a collaborative effort with the Public Service Commission of the State of Maryland to consider {open_quotes}reforms that enhance the industry`s competitiveness{close_quotes}. The initial focus of our collaborative effort was on gas purchasing and contract portfolios; however, it became apparent that efficient contracting to purchase and use gas requires a broader consideration of regulatory reform. Efficient portfolios are obtained when the holder of the portfolio is affected by and is responsible for the performance of the portfolio. Natural gas distribution companies may prefer a diversity of contracts, but the efficient use of gas requires that the local distribution company be held accountable for its own purchases. Ultimate customers are affected by their own portfolios, which they manage efficiently by making their own choices. The objectives of the DGOI, particularly the efficient use of gas, can be achieved when customers have access to suppliers of gas and energy services under an improved regulatory framework. The evolution of the natural gas market during the last 15 years is described to account for the changing preferences toward gas contracts. Long-term contracts for natural gas were prevalent before the early 1980s, primarily because gas producers had few options other than to sell to a single pipeline company, and this pipeline company, in turn, was the only seller to a gas distribution company.

Ideas and suggestions for marketing natural gas

Goldammer, D [Thyssengas G.m.b.H., Duisburg (Germany, F.R.)

1980-04-01

The changes in the situation on the world energy market have also affected the gas supply business. This led to a re-examination of the marketing concept for natural gas. The impetus to this came from the procurement situation, the rational use of energy, the appearance of new technologies and the need to arrive at a pricing policy in line with the market. All this required a great deal of PR work and more extensive cooperation. Clarification of some points will require a market analysis to show how long-term plans will have to be established. Sales promotion activities for natural gas will have to show that the aim is to use natural gas as a substitute in high-efficiency applications rather than to increase the consumption of energy. The various activities must be closely coordinated.

The new East Coast natural gas market

Market demand for natural gas in Canada's Maritime provinces was discussed. The Atlantic market represents the largest potential region, currently without access to natural gas in Canada or the United States. Maritimes and Northeast Pipelines and the Sable Offshore Energy partners have made great efforts to introduce and market natural gas as well as to provide pipeline transportation services in the Maritimes and New England markets. Maritimes and Northeast Pipelines is a partnership project with Westcoast Energy, Mobil Oil, and Duke Energy. Theirs is the first pipeline project to deliver gas, but it will certainly not be the last gas project in the region. Maritimes and Northeast Pipelines now has 180,000 MMBtu/day of phased-in Canadian load committed to firm service agreements for delivery in the first 24 months of operation. In addition to these firm service agreements, an additional 60,000 MMBtu/day is signed for future lateral extensions to service emerging markets. figs

Issues in Energy Economics Led by Emerging Linkages between the Natural Gas and Power Sectors

International Nuclear Information System (INIS)

Platt, Jeremy B.

2007-01-01

Fuel prices in 2006 continued at record levels, with uranium continuing upward unabated and coal, SO 2 emission allowances, and natural gas all softening. This softening did not continue for natural gas, however, whose prices rose, fell and rose again, first following weather influences and, by the second quarter of 2007, continuing at high levels without any support from fundamentals. This article reviews these trends and describes the remarkable increases in fuel expenses for power generation. By the end of 2005, natural gas claimed 55% of annual power sector fuel expenses, even though it was used for only 19% of electric generation. Although natural gas is enormously important to the power sector, the sector also is an important driver of the natural gas market-growing to over 28% of the market even as total use has declined. The article proceeds to discuss globalization, natural gas price risk, and technology developments. Forces of globalization are poised to affect the energy markets in new ways-new in not being only about oil. Of particular interest in the growth of intermodal traffic and its a little-understood impacts on rail traffic patterns and transportation costs, and expected rapidly expanding LNG imports toward the end of the decade. Two aspects of natural gas price risk are discussed: how understanding the use of gas in the power sector helps define price ceilings and floors for natural gas, and how the recent increase in the natural gas production after years of record drilling could alter the supply-demand balance for the better. The article cautions, however, that escalation in natural gas finding and development costs is countering the more positive developments that emerged during 2006. Regarding technology, the exploitation of unconventional natural gas was one highlight. So too was the queuing up of coal-fired power plants for the post-2010 period, a phenomenon that has come under great pressure with many consequences including increased

Energy efficiency at Hydro-Quebec: Why forget the substitution of electricity by natural gas?

International Nuclear Information System (INIS)

Bernard, J.-T.

1994-01-01

Hydro-Quebec has launched an energy program which will cost $1.9 billion and which intends to save 9.3 TWh of electricity consumption by the year 2000, equivalent to 5.6% of the forecasted electricity consumption. The program only considers electricity and ignores other energy sources. An analysis is conducted to determine whether the subsidies that Hydro-Quebec is prepared to spend in each sector of the program would be sufficient to make up the difference between the cost of electricity and that of natural gas for the end-user. A positive response to this question will allow identification of a less costly way that Hydro-Quebec could realize its energy efficiency objectives. The analysis takes into account the marginal cost of electricity production, the average cost of energy efficiency measures, electricity prices, and the prices of natural gas and of gas-burning equipment. The results of a detailed analysis of four typical cases in the residential and commercial sectors indicate that market segments exist in which an energy efficiency program that includes substitution of other forms of energy for electricity would be preferable to a simple reduction in electricity consumption. However, the rationale for the Hydro-Quebec program is that electricity prices are based on historical average costs; as a result, electricity prices are lower than marginal costs. This problem should be addressed before considering expensive energy efficiency programs where the least-cost alternative is not even considered. 5 refs., 1 fig., 2 tabs

The paper discusses the natural gas market and environmental needs with topics as follow: Importance of the North Sea region; sustainable development on the balance between economic use and environmental protection; role of natural gas in meeting energy demand: market needs, technologies, environmental aspects. According to the author, natural gas causes minimal pollutants because it contains virtually no pollutant-forming substances such as heavy metals, sulphur, chlorine or fluorine. No solid residues exist in the combustion space such as ash, slag, dust or soot, and the formation of thermal NO x through natural gas combustion has decreased to a very large extent as a result of technical advances. Natural gas can make a significant contribution towards reducing CO 2 emissions due to its very high hydrogen content. 12 figs

Energy and exergy recovery in a natural gas compressor station – A technical and economic analysis

Kostowski, Wojciech J.; Kalina, Jacek; Bargiel, Paweł; Szufleński, Paweł

2015-01-01

Highlights: • Energy and exergy flow in a natural gas compressor station. • Operational efficiency only 18.3% vs. 35.1% nominal. • 3 energy/exergy recovery systems proposed. • Up to 168.9 GW h/y electricity and 6.5 GW h/y heat recoverable. • Legal obstacles: operators not allowed to produce electricity. - Abstract: The paper presents possible solutions to improve the thermodynamic performance of a natural gas compressor station equipped with various type of compressor units and operated at part-load conditions. A method for setting a simplified energy and exergy balance based on the available metering information has been presented. For a case study plant, it has been demonstrated that the current part-load operation leads to a significant decrease in energy and exergy efficiency compared to the nominal state of machinery. Three alternative improvement strategies have been proposed: (1) installation of a heat recovery hot water generator for covering the existing heat demand of the plant; (2) installation of a heat recovery thermal oil heater for covering the existing heat demand and driving an organic Rankine cycle (ORC) for electricity generation; (3) installation of a heat recovery thermal oil heater with and ORC and gas expanders for switching into full-load operation of the gas turbine unit. Energy and exergy performance of the proposed strategies as well as their economic feasibility have been analyzed. The second scenario involving an ORC unit provides the highest local energy savings, however, its economic feasibility is not achieved under the current part-load operating conditions. A hypothetic scenario of the same station operated at full-load due to an increased gas transmission capacity demonstrate the economic feasibility (possible under optimistic price conditions). Finally, it has been shown that the possibility of waste energy recovery from natural gas transmission systems (in particular, from compressor stations) depends on legal

Worldwide natural gas is forecasted to be the fastest growing primary energy source. In Egypt, natural gas is recently playing a key role as one of the major energy sources. This is supported by adequate gas reserves, booming gas industry, and unique geographical location. Egypt's current proven gas reserves accounted for about 62 TCF, in addition to about 100 TCF as probable gas reserves. As a result, it was decided to enter the gas exporting market, where gas is transported through pipelines as in the Arab Gas pipelines project and as a liquid through the liquefied natural gas (LNG) projects in Damietta, and ld ku. With the start up of these currently implemented LNG projects that are dealing with the very low temperatures (down to -162 degree c), the gas has to be subjected to a regular analysis in order to check the compliance with the required specifications. Mercury is a trace component of all fossil fuels including natural gas, condensates, crude oil, coal, tar sands, and other bitumens. The use of fossil hydrocarbons as fuels provides the main opportunity for emissions of mercury they contain to the atmospheric environment: while other traces exist in production, transportation and processing systems

1992-01-01

The evolution of energy market shares (electricity, natural gas and oil products) in Quebec's residential and commercial sectors in the 1980s shows that energy source relative prices have influenced consumer behavior as expected. A set of comparisons from space and water heating markets in these sectors with regard to prices paid by consumers and costs incurred by society in general is presented. For the residential sector, it is seen that consumers pay only a fraction of the cost for electric space and water heating; the same service could be provided at smaller cost by natural gas. For the commercial sector, the electricity and natural gas tariffs convey the appropriate message with respect to the cost incurred in providing the service. 6 refs., 7 tabs

This PowerPoint presentation identified natural gas as part of the electricity solution. It reviewed price implications and policy recommendations. New natural gas supply is not keeping pace with demand. Production is leveling out in traditional basins and industry investment is not adequate. In addition, energy deregulation is creating disconnects. This presentation included a map depicting the abundant natural gas reserves across North America. It was noted that at 2002 levels of domestic production, North America has approximately 80 years of natural gas. The AECO consensus wholesale natural gas price forecast is that natural gas prices in 2010 will be lower than today. The use of natural gas for power generation was outlined with reference to fuel switching, distributed generation, and central generation. It was emphasized that government, regulators and the energy industry must work together to address policy gaps and eliminate barriers to new investment. tabs., figs

Securing growth markets for natural gas

The Industry Development Strategy 2000-2005 (IDS) identifies the major growth markets for natural gas, as the industry readies itself for the challenges of the new millenium. An integral part of this process is to examine the key barriers to market expansion, and to devise strategies that both The Australian Gas Association (AGA) and the wider industry can pursue to underpin improvement in overall gas consumption. This is the task of the IDS which examines the opportunities confronting the industry over the next five year period. The significant growth prospects of the gas industry both in the short term (2000-2005) and long term (2005-2015) are indicated in two comprehensive and independent studies. The first, Australian Energy Market Developments and Projections to 2014-15, was released earlier this year by the Australian Bureau of Agricultural and Resource Economics (the ABARE Energy Report). The second, Natural Gas Consumption in Australia to 2015-Prospects by State, Industry and Sector, was commissioned by the AGA, and was completed by the National Institute of Economic and Industry Research in September 1999 (NIEIR Report). Both reports indicate that in terms of consumption levels, in the period up to 2015 the gas industry is forecast to more than double its current size. Natural gas is also projected to increase its primary energy share ranking from third to second place

The development of the worldwide natural gas industry and the importance that this energy source has acquired in the energy matrix of various countries has given rise to certain uneasiness amongst the importing countries regarding the increase in gas dependence. This preoccupation is due to the fact that natural gas occurs in concentrated areas and that its major producers have joined together in the Gas Exporter Countries Forum, giving rise to a debate of the possibility of this Forum developing into cartel configuration. This paper aims at an analysis of the viability of cartel formation in the natural gas industry, following the same model as that of the oil industry. Considering the basic conditions necessary for successful cartel activities in the natural gas industry, the text presents some factors that can indeed contribute towards collusion among the exporting countries. However, the positive effects that a gas cartel can generate for the exporting countries are not guaranteed. On the contrary, what is actually observed are conditions favorable to the rupture of collusive deals and to an increase in the penetration of substitute energy sources, given that monopoly prices are fixed to the natural gas by the cartel.

The determining factors of natural gas demand in domestic sector

International Nuclear Information System (INIS)

Cadoret, I.

1992-01-01

Natural gas plays an important role in domestic sector. For example, in France, Italy, Germany and United-Kingdom the natural gas share in energy demand of domestic sector is respectively 26%, 44%, 34% and 63%. A study of energy policies, natural gas industry structure and tarification system of this four countries indicates that gas development is linked to the government and petroleum companies policy. Econometric models estimation show by another way that when natural gas is introduced in domestic sector, the demand follows the distribution network. When the market is saturated, the demand changes with energy price and household income. 8 refs., 2 tabs., 5 figs

Energy transition: gas asserts its assets

International Nuclear Information System (INIS)

Passebon, Philippe; Lesquel, Emmanuelle; Leroux, Hugo

2016-01-01

Even though it is a fossil energy, gas has a role to play in energy transition as it emits less CO 2 than oil or coal. In this context, it can be used to fill the gaps due to intermittency of some renewable energies, and moreover can also be obtained from organic matter, and then becomes also a renewable source. A set of articles addresses and illustrates these different issues: the development of technologies to exploit methane, the role of substitute for gas, the assets of methane, of natural gas and of biogas, the transformation of electricity into gas in order to easily store energy (notably in the network gas according to the power-to-gas principle), the development of biomass-based methane, the replacement of oil by LNG (liquefied natural gas) in industry and transports (road and sea transport notably)

Adsorptive storage of natural gas

International Nuclear Information System (INIS)

Yan, Song; Lang, Liu; Licheng, Ling

2001-01-01

The Adsorbed Natural Gas (ANG) storage technology is reviewed. The present status, theoretical limits and operational problems are discussed. Natural gas (NG) has a considerable advantage over conventional fuels both from an environmental point of view and for its natural abundance. However, as well known, it has a two fold disadvantage compared with liquid fuels: it is relatively expensive to transport from the remote areas, and its energy density (heat of combustion/volume) is low. All these will restrict its use. Compressed natural gas (CNG) may be a solution, but high pressures are needed (up to 25 MPa) for use in natural-gas fueled vehicles, and the large cost of the cylinders for storage and the high-pressure facilities necessary limit the practical use of CNG. Alternatively, adsorbed natural gas (ANG) at 3 - 4 MPa offers a very high potential for exploitation in both transport and large-scale applications. At present, research about this technology mainly focuses on: to make adsorbents with high methane adsorption capacity; to make clear the effects of heat of adsorption and the effect of impurities in natural gas on adsorption and desorption capacity. This paper provides an overview of current technology and examines the relations between fundamentals of adsorption and ANG storage. (authors)

Preliminary assessment of the availability of U.S. natural gas resources to meet U.S. transportation energy demand

International Nuclear Information System (INIS)

Singh, M. K.; Moore, J. S.

2002-01-01

Recent studies have indicated that substitutes for conventional petroleum resources will be needed to meet U.S. transportation energy demand in the first half of this century. One possible substitute is natural gas which can be used as a transportation fuel directly in compressed natural gas or liquefied natural gas vehicles or as resource fuel for the production of hydrogen for fuel cell vehicles. This paper contains a preliminary assessment of the availability of U.S. natural gas resources to meet future U.S. transportation fuel demand. Several scenarios of natural gas demand, including transportation demand, in the U.S. to 2050 are developed. Natural gas resource estimates for the U. S. are discussed. Potential Canadian and Mexican exports to the U.S. are estimated. Two scenarios of potential imports from outside North America are also developed. Considering all these potential imports, U.S. natural gas production requirements to 2050 to meet the demand scenarios are developed and compared with the estimates of U.S. natural gas resources. The comparison results in a conclusion that (1) given the assumptions made, there are likely to be supply constraints on the availability of U.S. natural gas supply post-2020 and (2) if natural gas use in transportation grows substantially, it will have to compete with other sectors of the economy for that supply-constrained natural gas

After an opening speech, which insisted on the fact that natural gas is now recognized as a low greenhouse gas emission energy source, and a presentation of the gas demand scenario for 2030, two round tables addressed the new utilizations of natural gas (LNG for ships and vehicles, power generation, biomethane, cryogenics, heating systems), and the contributions of new technologies (and more especially digital systems) in the natural gas market and gas utilities

Natural gas and production of electricity

International Nuclear Information System (INIS)

Defago, E.

2005-01-01

The forthcoming power supply shortage in Switzerland due to increasing consumption is discussed, as are the possibilities for securing the future supply. Today, the main sources are hydroelectric (roughly 55 %) and nuclear (40 %) power. The share of electricity from natural gas amounts to only 1.4 %. The possibilities of further economic production of hydropower are practically exhausted. Therefore, further electric power has to be either imported or generated from other energy sources (renewable, nuclear, fossil) in the country itself. Due to the low acceptance of nuclear energy and the limited potential of renewable energy sources, natural gas is the most favoured candidate. The advantages of distributed production in cogeneration plants are compared with the centralized production in larger plants using combined cycles. Finally, a project currently under development is presented: an existing thermal power plant fueled with heavy fuel oil shall be refurbished and converted to natural gas as the new fuel

Liquefied Natural Gas for Trucks and Buses

International Nuclear Information System (INIS)

James Wegrzyn; Michael Gurevich

2000-01-01

Liquefied natural gas (LNG) is being developed as a heavy vehicle fuel. The reason for developing LNG is to reduce our dependency on imported oil by eliminating technical and costs barriers associated with its usage. The U.S. Department of Energy (DOE) has a program, currently in its third year, to develop and advance cost-effective technologies for operating and refueling natural gas-fueled heavy vehicles (Class 7-8 trucks). The objectives of the DOE Natural Gas Vehicle Systems Program are to achieve market penetration by reducing vehicle conversion and fuel costs, to increase consumer acceptance by improving the reliability and efficiency, and to improve air quality by reducing tailpipe emissions. One way to reduce fuel costs is to develop new supplies of cheap natural gas. Significant progress is being made towards developing more energy-efficient, low-cost, small-scale natural gas liquefiers for exploiting alternative sources of natural gas such as from landfill and remote gas sites. In particular, the DOE program provides funds for research and development in the areas of; natural gas clean up, LNG production, advanced vehicle onboard storage tanks, improved fuel delivery systems and LNG market strategies. In general, the program seeks to integrate the individual components being developed into complete systems, and then demonstrate the technology to establish technical and economic feasibility. The paper also reviews the importance of cryogenics in designing LNG fuel delivery systems

Safety implications of bridging the energy supply/demand gap in Nigeria through associated natural gas utilization

International Nuclear Information System (INIS)

Akeredolu, Funso A.; Sonibare, Jacob A.

2007-01-01

There exists a wide energy supply/demand gap in Nigeria. The local generation of electricity meets only 31% of the demand of 10000 MW. By contrast, only 39.6% of the total installed capacity for electricity generation is achieved, owing to aging infrastructure, etc. The energy demand/supply pattern and infrastructure critically reviewed thus suggested the need to increase the electricity generation capacity. Furthermore, Nigeria flares 77% of her associated natural gas. Apart from the environmental penalties that flaring represents, in monetary terms, over the 110 years' life of Nigeria's gas reserves, a conservative estimate of the cost of the gas so-flared was $330 billion (based on $20/barrel average price of crude). It was safely inferred that the way forward in meeting the country's energy demand should include a strong element of gas utilization. In previous publications by this group, it was established that while domestic cooking could reduce the flared gas by about 5.4%, a cohesive policy on associated gas use for electricity generation could eliminate gas flaring. For domestic utilization of the associated gas, burner design and safety concerns were identified as the key challenges to overcome. The paper reports the effectiveness of odorizers in leakage detection/ prevention by the local consumers. It also discusses the issue of prevention of gas explosions. The previous cases of gas accidents were reviewed. The safety approaches proffered in the paper identified the relevant areas of research for safe delivery and consumption of natural gas in Nigeria.

Distributed Energy Generation Systems Based on Renewable Energy and Natural Gas Blending: New Business Models for Economic Incentives, Electricity Market Design and Regulatory Innovation

Science.gov (United States)

Nyangon, Joseph

Expansion of distributed energy resources (DERs) including solar photovoltaics, small- and medium-sized wind farms, gas-fired distributed generation, demand-side management, and energy storage poses significant complications to the design, operation, business model, and regulation of electricity systems. Using statistical regression analysis, this dissertation assesses if increased use of natural gas results in reduced renewable energy capacity, and if natural gas growth is correlated with increased or decreased non-fossil renewable fuels demand. System Generalized Method of Moments (System GMM) estimation of the dynamic relationship was performed on the indicators in the econometric model for the ten states with the fastest growth in solar generation capacity in the U.S. (e.g., California, North Carolina, Arizona, Nevada, New Jersey, Utah, Massachusetts, Georgia, Texas, and New York) to analyze the effect of natural gas on renewable energy diffusion and the ratio of fossil fuels increase for the period 2001-2016 to policy driven solar demand. The study identified ten major drivers of change in electricity systems, including growth in distributed energy generation systems such as intermittent renewable electricity and gas-fired distributed generation; flat to declining electricity demand growth; aging electricity infrastructure and investment gaps; proliferation of affordable information and communications technologies (e.g., advanced meters or interval meters), increasing innovations in data and system optimization; and greater customer engagement. In this ongoing electric power sector transformation, natural gas and fast-flexing renewable resources (mostly solar and wind energy) complement each other in several sectors of the economy. The dissertation concludes that natural gas has a positive impact on solar and wind energy development: a 1% rise in natural gas capacity produces 0.0304% increase in the share of renewable energy in the short-run (monthly) compared

Industrial natural gas supply options in British Columbia

International Nuclear Information System (INIS)

1994-01-01

Information is provided on the availability and cost of natural gas in British Columbia for use by firms interested in establishing gas-intensive industrial facilities in the province. British Columbia has an abundant supply of natural gas, originating mainly from deposits in the westernmost part of the Western Canadian Sedimentary Basin in the northeast part of the province. Recoverable resources in British Columbia are estimated at 1,000-1,400 billion m 3 . Over 200 producers compete to sell natural gas for both domestic and export markets. Gathering, processing, and transmission of the gas is undertaken mainly by the Westcoast Energy pipeline system, and distribution is undertaken by several distribution utilities. At present, all large industrial gas users buy their firm gas requirements directly from gas producers, often using gas marketers or brokers to assist in purchasing. Regulation of the gas industry is performed by the British Columbia Utilities Commission, which sets rules for energy supply contracts, and by the National Energy Board, which sets tolls for gathering, processing, and transporting gas. Factors affecting gas pricing are discussed, with reference to both the wellhead price and the cost of gathering, processing, and transportation. Firm gas costs for two hypothetical industrial loads in British Columbia are illustrated. Potential intensive uses of natural gas in the province are outlined, including power generation, liquefaction for export, manufacturing, production of direct reduced iron, and as petrochemical feedstocks. 5 figs., 2 tabs

Gas hydrate is a naturally occurring, ice-like substance that forms when water and gas combine under high pressure and at moderate temperatures. Methane is the most common gas present in gas hydrate, although other gases may also be included in hydrate structures, particularly in areas close to conventional oil and gas reservoirs. Gas hydrate is widespread in ocean-bottom sediments at water depths greater than 300–500 meters (m; 984–1,640 feet [ft]) and is also present in areas with permanently frozen ground (permafrost). Several countries are evaluating gas hydrate as a possible energy resource in deepwater or permafrost settings. Gas hydrate is also under investigation to determine how environmental change may affect these deposits.

Measuring energy security: Trends in the diversification of oil and natural gas supplies

Cohen, Gail; Joutz, Frederick; Loungani, Prakash

2011-01-01

We present evidence on one facet of energy security in OECD economies-the extent of diversification in sources of oil and natural gas supplies. Viewed from the perspective of the energy-importing countries as a whole, there has not been much change in diversification in oil supplies over the last decade, but diversification in sources of natural gas supplies has increased steadily. We document the considerable cross-country heterogeneity in the extent of diversification. We also show how the extent of diversification changes if account is taken of the political risk attached to suppliers; the size of the importing country; and transportation risk. - Highlights: → Global diversification is constant but large differences exist among countries. → Political risk and distance have large impacts on diversity measures. → Size has little impact on diversity measures. → France, US, and UK show low vulnerability for both fuels. → Smaller European countries show high vulnerability for both fuels.

Operation and planning of coordinated natural gas and electricity infrastructures

Science.gov (United States)

Zhang, Xiaping

Natural gas is becoming rapidly the optimal choice for fueling new generating units in electric power system driven by abundant natural gas supplies and environmental regulations that are expected to cause coal-fired generation retirements. The growing reliance on natural gas as a dominant fuel for electricity generation throughout North America has brought the interaction between the natural gas and power grids into sharp focus. The primary concern and motivation of this research is to address the emerging interdependency issues faced by the electric power and natural gas industry. This thesis provides a comprehensive analysis of the interactions between the two systems regarding the short-term operation and long-term infrastructure planning. Natural gas and renewable energy appear complementary in many respects regarding fuel price and availability, environmental impact, resource distribution and dispatchability. In addition, demand response has also held the promise of making a significant contribution to enhance system operations by providing incentives to customers for a more flat load profile. We investigated the coordination between natural gas-fired generation and prevailing nontraditional resources including renewable energy, demand response so as to provide economical options for optimizing the short-term scheduling with the intense natural gas delivery constraints. As the amount and dispatch of gas-fired generation increases, the long-term interdependency issue is whether there is adequate pipeline capacity to provide sufficient gas to natural gas-fired generation during the entire planning horizon while it is widely used outside the power sector. This thesis developed a co-optimization planning model by incorporating the natural gas transportation system into the multi-year resource and transmission system planning problem. This consideration would provide a more comprehensive decision for the investment and accurate assessment for system adequacy and

1989-01-01

The Gas Analysis Modeling System is a large computer-based model for analyzing the complex US natural gas industry, including production, transportation, and consumption activities. The model was developed and first used in 1982 after the passage of the NGPA, which initiated a phased decontrol of most natural gas prices at the wellhead. The categorization of gas under the NGPA and the contractual nature of the natural gas market, which existed at the time, were primary factors in the development of the basic structure of the model. As laws and regulations concerning the natural gas market have changed, the model has evolved accordingly. Recent increases in competition in the wellhead market have also led to changes in the model. GAMS produces forecasts of natural gas production, consumption, and prices annually through 2010. It is an engineering-economic model that incorporates several different mathematical structures in order to represent the interaction of the key groups involved in the natural gas market. GAMS has separate supply and demand components that are equilibrated for each year of the forecast by means of a detailed transaction network

Natural gas fuel is a green fuel and becoming very demanding because it is environmental safe and clean. Furthermore, this fuel emits lower levels of potentially harmful by-products into the atmosphere. Most of the explored crude natural gas is of sour gas and yet, very viable and cost effective technology is still need to be developed. Above all, methanation technology is considered a future potential treatment method for converting the sour natural gas to sweet natural gas.

Natural gas: a rose by any other name

Natural gas is expected to provide 30% of the European Union's energy demand by 2020 as compared with 20% in 1995. Although price is still used as a selling point for gas, its increasing popularity and market share are assisted by its image. It is perceived as both 'clean' and 'modern' and indeed its environmental credentials are good compared with those of oil and coal. A gigajoule of energy generated using oil or gas produces 53% or 83% more carbon dioxide, respectively, than using natural gas because of the combustion efficiency of the methane molecule. The significance of the adjective 'natural' as an added marketing advantage is discussed. (UK)

The reform of the EEG in Germany, a positive global development in natural gas, the decline in oil prices, questions about the security of supply in Europe, and not least the effect of the decision by E.on at the end of 2014 have moved the gas industry. Gas has the lowest CO{sub 2} emissions of fossil fuels. Flexibility, storability, useful for networks and the diversity in the application make it an ideal partner for renewable energy. However, these complementary properties are valued at wind and photovoltaics internationally and nationally different. The situation in the gas power plants remains tense. LNG - liquefied natural gas - is on the rise.

Climate change, global warming, urban air pollution, energy supply uncertainty and depletion, and rising costs of conventional energy sources are, among others, potential socioeconomic threats that our community faces today. Transportation is one of the primary sectors contributing to oil consumption and global warming, and natural gas (NG) is considered to be a relatively clean transportation fuel that can significantly improve local air quality, reduce greenhouse-gas emissions, and decrease the energy dependency on oil sources. Internal combustion engines (ignited or compression) require only slight modifications for use with natural gas; rather, the main problem is the relatively short driving distance of natural-gas-powered vehicles due to the lack of an appropriate storage method for the gas, which has a low energy density. The U.S. Department of Energy (DOE) has set some targets for NG storage capacity to obtain a reasonable driving range in automotive applications, ruling out the option of storing methane at cryogenic temperatures. In recent years, both academia and industry have foreseen the storage of natural gas by adsorption (ANG) in porous materials, at relatively low pressures and ambient temperatures, as a solution to this difficult problem. This review presents recent developments in the search for novel porous materials with high methane storage capacities. Within this scenario, both carbon-based materials and metal-organic frameworks are considered to be the most promising materials for natural gas storage, as they exhibit properties such as large surface areas and micropore volumes, that favor a high adsorption capacity for natural gas. Recent advancements, technological issues, advantages, and drawbacks involved in natural gas storage in these two classes of materials are also summarized. Further, an overview of the recent developments and technical challenges in storing natural gas as hydrates in wetted porous carbon materials is also included

The Pricing of natural gas

International Nuclear Information System (INIS)

Nese, Gjermund

2004-11-01

The report focuses on the pricing of natural gas. The motivation has been the wish of the Norwegian authorities to increase the use of natural gas and that this should follow market conditions. The pricing of gas occurs at present in various ways in the different markets. The report identifies to main factors behind the pricing. 1) The type of market i.e. how far the liberalization of the gas markets has gone in the various countries. 2) The development within the regulation, climate and tax policies. The gas markets are undergoing as the energy markets in general, a liberalization process where the traditional monopoly based market structures are replaced by markets based on competition. There are great differences in the liberalization development of the various countries, which is reflected in the various pricing principles applied for the trade of gas in the countries. The analysis shows that the net-back-pricing is predominant in some countries i.e. that the price is in various ways indexed towards and follow the development of the price of alternative energy carriers so that the gas may be able to compete. The development towards trade places for gas where the pricing is based on offer and demand is already underway. As the liberalization of the European gas markets progresses it is expected that the gas price will be determined increasingly at spot markets instead of through bilateral agreements between monopolistic corporations. The development within the regulation, climate and tax policies and to what extent this may influence the gas prices in the future, are also studied. There seem to be effects that may pull in both directions but it is evident that these political variables will influence the gas pricing in the international market to a large extent and thereby also the future internal natural gas market

Gunnung, P.

2000-01-01

The structure of two EPA programs directed towards wasted energy in buildings, reducing emissions, increasing energy efficiency and maximizing profits are described. The programs are based on a partnership approach between EPA and participants, and involve elements of plans and performance benchmarks, an integrated approach and communications and demonstration of successful initiatives. EPA provides planning and technical support in the form of a website, software tools, manuals, electronic sources and a purchasing tool kit. The Energy STAR Building Partnership has over 3,000 participants, and can boast of a cumulative saving of over $ 1.4 billion in energy bills and carbon dioxide emission reduction of 44.1 billion pounds, resulting from efficiency upgrades. The Natural Gas Partnership between the EPA and the oil and natural gas industry to cost effectively reduce methane emissions from the production, transmission, and distribution of natural gas also has had a number of successful initiatives such as replacement or retrofit of high bleed pneumatic devices, installation of flash tank separators on glycol dehydrators and other partner-reported projects such as replacement of wet seals with dry seals on compressors and connecting glycol pump to vapour recovery unit. As a results of these and other initiatives, annual methane emission was reduced by 22.2 bcf in 1998 as opposed to 3.4 bcf prior to the beginning of the program in 1993. Approximately 67 per cent of all reductions can be attributed to partner innovation. Overall assessment is that the program is innovative, achieves both economic and environmental goals, facilitates government and industry cooperation and is living proof that non-regulatory, cooperative programs work

This books includes two articles, each with an abstract dealing with the economic aspects of natural gas usage and solar energy usage both depending on the data about weather forecasting. The demand of natural gas depends on weather and the analysis of gas usage is required in a rate case in order to properly estimate the volumes and revenues that would be recovered from current rate under conditions of normal weather. The actual uses of the principal types of solar energy systems, based on their climatic, technological and economical context are needed for future estimation concerning this energy sources which would have a more significant role in the future

A series of overhead viewgraphs accompanied this presentation which presented an update of North American natural gas supply. Some of the graphs depicted the following: (1) natural gas consumption in the United States, (2) U.S. imports of Canadian natural gas, (3) natural gas prices differential: Henry Hub versus Empress, (4) natural gas production in the U.S., and (5) Baker Hughes active rig count, U.S. gas rigs. First Energy's view of U.S. natural gas supply is that the estimate of 50.0 Bcf/d for U.S. domestic production is looking too high. The first quarter 1999 exit production rates are behind expectations. U.S. domestic natural gas expenditure budgets are still down by more than 40 per cent compared to 1998 levels. The impact that this will have on prices was discussed. 21 figs

The Energy Modeling Forum (EMF) was established in 1976 at Stanford University to provide a structural framework within which energy experts, analysts, and policymakers could meet to improve their understanding of critical energy problems. The ninth EMF study, North American Natural Gas Markets, was conducted by a working group comprised of leading natural gas analysts and decision-makers from government, private companies, universities, and research and consulting organizations. The EMF 9 working group met five times from October 1986 through June 1988 to discuss key issues and analyze natural gas markets. This third volume includes technical papers that support many of the conclusions discussed in the EMF 9 summary report (Volume 1) and full working group report (Volume 2). These papers discuss the results from the individual models as well as some nonmodeling analysis related to US natural gas imports and industrial natural gas demand. Individual papers have been processed separately for inclusion in the Energy Science and Technology Database.

Turkey is an important candidate to be the 'energy corridor' in the transmission of the abundant oil and natural gas resources of the Middle East and Middle Asia countries to the Western market. Furthermore, Turkey is planning to increase its oil and gas pipeline infrastructure to accommodate its increased energy consumption. Naturally, Turkish natural gas usage is projected to increase remarkably in coming years, with the prime consumers, expected to be industry and power plants. Energy demand of Turkey is growing by 8% annually, one of the highest rates in the world. In addition, natural gas consumption is the fastest growing primary energy source in Turkey. Gas sales started at 0.5 bcm (billion cubic meters), in 1987 and reached approximately 22 bcm in 2003. This article deals with energy policies and natural gas consumption of Turkey. Besides modernization of present lines and realization of capacity increase, new lines will also be needed. In this context, Turkey, due to its geographical location is, in an important position to vary European supply. Therefore, Turkey's role as a transitory area gains importance.

The future of the US natural gas market

Linden, H.R.

1993-01-01

The United States gas industry is entering a period when it will have an excellent opportunity to recapture the 30 percent share of the primary energy market it enjoyed in 1973. In spite of unresolved problems stemming from its drastic restructuring during the Reagan and Bush administrations, most aspects of today's political and regulatory climate favor a substantial expansion of natural gas use in the economy. Combined with the now nearly universal recognition that Lower-48 natural gas resources and North American resources as a whole are abundant and recoverable at relatively low cost, this has created unusually high levels of preference for natural gas as a primary energy source. The favorable outlook for the US gas industry at the start of 1993 is the result of an extremely positive political, regulatory, and business climate for expanded use of natural gas, supported by a Lower-48 resource base capable of meeting expected levels of demand at competitive costs for at least 25 years. This assumes continued advances in the whole spectrum of technologies from exploration and production to end use that halted and partially reversed the sharp 1973 to 1986 decline of gas share of the US energy market. In addition to the uncertainties that cloud this assumption, as the gas industry's commitment to aggressive support of R ampersand D seems to be faltering, there are other problems that need to be resolved to ensure the full realization of the potential of gas as the bridge fuel to a sustainable energy system

This report sunnnarizes the research by an Energy Modeling Forum working group on the evolution of the North American natural gas markets between now and 2010. The group's findings are based partly on the results of a set of economic models of the natural gas industry that were run for four scenarios representing significantly different conditions: two oil price scenarios (upper and lower), a smaller total US resource base (low US resource case), and increased potential gas demand for electric generation (high US demand case). Several issues, such as the direction of regulatory policy and the size of the gas resource base, were analyzed separately without the use of models.

Electric utilities and the demand for natural gas

Energy Technology Data Exchange (ETDEWEB)

Uri, N D; Atkinson, S

1976-03-01

The scarcity of natural gas has given rise to a series of priorities of deliveries based on end use and drafted by the Federal Power Commission. The U.S. Supreme Court, on June 7, 1972, held that the Commission has jurisdiction over curtailments in the service of gas in interstate commerce to both resale and direct industrial customers. This decision reversed a Fifth Circuit Court ruling that protected direct industrial customers from curtailments. The FPC priority curtailments are classed from 1 to 9, for which electric utilities are concentrated in classes 4 to 9. As weather conditions become more severe, not only do the residential and commercial consumers demand more electrical energy, they also demand more natural gas. The result is that there is less natural gas available for electric utilities to use for generation so they change to an alternative fuel. A demand model for the short term for natural gas for electric utilities is given; primary factors involve the price of natural gas, the prices of substitute fuels, and the demand for electrical energy by the various consumer classes.

Natural gas, whose primary constituent is methane, has been considered a convincing alternative for the growth of the energy supply worldwide. Adsorbed natural gas (ANG), the most promising methane storage method, has been an active field of study in the past two decades. ANG constitutes a safe and low-cost way to store methane for natural gas vehicles at an acceptable energy density while working at substantially low pressures (3.5-4.0 MPa), allowing for conformable store tank. This work serves to review the state-of-the-art development reported in the scientific literature on adsorbents, adsorption theories, ANG conformable tanks, and related technologies on ANG vehicles. Patent literature has also been searched and discussed. The review aims at illustrating both achievements and problems of the ANG technologies- based vehicles, as well as forecasting the development trends and critical issues to be resolved of these technologies.

For the planning of the natural gas sector in the mark of the analysis integrated energy planning, it is required of the simultaneous study of a great quantity of present factors in the development of this industry, which could give an idea of the diversity of circumstances that it allow a successful evolution of the gas sector. The national market of the natural gas, was limited by offer restrictions and for lack of an appropriate infrastructure of production and transport of this energy. The existent markets until the present time (1997) they have been developed around to the discovered locations in three defined areas that is: Atlantic Coast, where they are the most important producing fields in free gas; Santander and Huila departments, and the center of the country. The readiness of new discovered reserves of gas in Cusiana, Cupiagua, Opon and the perspectives of others in Volcanero, Florena and Pauto, they have strengthened the politics of overcrowding of gas consumption, whose fundamental objective is to develop a efficient and more convenient energy consumption for the country, by means of the energy resources substitution of high cost, initially for GLP and later on for the overcrowding of the natural gas

Energy market liberalization is a world trend that has prompted the deregulation of natural gas and electricity over the past twenty years in North America. The Ontario Energy Board and the National Energy Board are conducting public hearings on natural gas regulation in response to the request by Canadian energy industries for better regulatory streamlining. The following 5 issues regarding natural gas regulation in Canada have been examined: (1) system gas in a regulated market, (2) natural gas infrastructure investments and capital renewal, (3) improving efficiency in gas regulation, (4) expectations of performance-based regulation (PBR) in the natural gas industry, and (5) the debate whether further deregulation of the natural gas industry is beneficial. This paper examines if a competitive market exists in natural gas distribution and discusses the opportunities for further deregulation of the distribution and storage aspects of the industry. It was noted that the regulatory regime in Ontario will depend on how the Ontario Energy Board deals with issues regarding natural gas storage services. This paper also examines if new storage facilities can charge cost-based or market-based prices as well as the appropriate rate of return on capital to be used to determine those rates. It also examines what the requirement for non-discriminatory access to and from new storage facilities to the Dawn Hub and access to transmission capacity on Union Gas's Dawn to Trafalger pipeline system. Alternative fuels, franchises, bypasses, gated communities, distributed generation, market power and policy issues are the main factors that are considered in assessing the competition in natural gas distribution. It was concluded that further deregulation of the natural gas distribution system in Ontario is not warranted since there is not much possibility in developing a competitive market for distribution services in the short-term. However, the development of storage facilities

The study, 'Assesment of greenhouse gas emission from natural gas' by independent consultants Energetics Pty Ltd, shows that natural gas has significantly fewer greenhouses gas emissions than either black or brown cola for the defined life cycle stages. The life cycle emissions from natural gas use by an Australian Major User are approximately 50% less than the emissions from Victorian brown coal and approximately 38% less than the emissions from Australian average black coal. Australian Best Practice gas fired electricity generation is estimated to emit between 514 and 658 kg CO 2 e/MWh. By comparison, Australian Best Practice coal-fired electricity generation is estimated to emit between 907 and 1,246 kg CO 2 e/MWh for black and brown coal respectively. Greenhouse gas emissions from Australian Best Practice gas-fired electricity generation using combined cycle gas turbines (including full fuel cycle emissions) vary from 41% to 46% of the emissions from brown coal-fired electricity generation and 57% to 64% of emissions from black coal-fired electricity generation. Greenhouse gas emissions from direct gas supply water heating range from 1,470 to 2,042 kilograms per annum. This compares with emissions of 1,922 to 2,499 kg for electric heating from gas-fired electricity generation and 3,975 to 5,393 kg for coal-fired electricity generation. The implications for greenhouse policy nationally are also discussed, emphasising the need to review national energy policy, currently tied to 'fuel neutrality' doctrine

This article aims to analyze the possibility of insertion of hydrogen in the vehicular natural gas or even the insertion of the hydrogen in the compressed natural gas used in Brazil. For the production of this hydrogen, the spilled turbinable energy from Itaipu would be harnessed. The calculation of production can be extended to other power plants which are close to the natural gas pipelines, where the hydrogen would be introduced. Then, it was analyzed the consumption of natural gas in vehicles in Brazil, the regulation of transportation, the sales of compressed natural gas to fuelling station, the specifications that the piped gas should follow to be sold, and how much hydrogen could be accepted in the mix.

The natural gas is natural origin energy (fossil fuel); it contains predominantly 90 percent methane; does not require transformation process for its use; is supplied the 24 hours to commerce, industries and homes by underground pipes; it is lighter than air; it is not corrosive, nor absorbent or toxic. For those reasons a study was performed where it is widely justified why the natural gas ought to be used in vehicles. [Spanish] El gas natural es un energetico de origen natural (combustible fosil), contiene predominantemente 90 por ciento de metano, no requiere proceso de transformacion para su utilizacion, llega directamente las 24 horas del dia a los hogares, comercios e industrias por tuberias subterraneas, es mas ligero que el aire, no es corrosivo, no es absorbente y no es toxico. Por esas razones se hizo un estudio donde se justifica ampliamente porque el gas natural debe utilizarse en vehiculos.

As low carbon-emitting fossil fuel, the natural gas is mainly used for power generation and industrial applications. It is also used for heating and cooling in commercial and residential buildings as well as in transport industry. Although the natural gas reaches the end-user mainly through pipelines (if gas is available locally), the liquefied form is the most viable alternative to transport natural gas from far away location to the end user. The economic progress in Asia and other parts of the world creates huge demand for energy (oil, gas and coal). As low carbon-emitting fuel, the demand for gas especially in liquefied form is progressively rising. Having 7th largest shale gas reserve (437 trillion cubic feet recoverable), Australia has become one of the world's major natural gas producers and exporters and is expected to continue a dominating role in the world gas market in foreseeable future. This paper reviews Australia's current gas reserve, industries, markets and LNG production capabilities.

Oil and natural gas strategies for North American energy markets: a submission by the Canadian Association of Petroleum Producers

International Nuclear Information System (INIS)

2001-04-01

This proposal by the Canadian Association of Petroleum Producers (CAPP) focuses on improving North American energy markets and addressing the challenges involved in meeting continental energy requirements by urging a renewed policy effort to enhance the current market-based policies of free trade and competition that have already proven to respond to market changes better than command-control government policies. The proposal urges new strategies to support development of the oil and natural gas resources of North America, and the development of additional infrastructure to bring oil and natural gas supplies to market. The new strategy should be based on the success of free trade to increase non-discriminatory treatment of energy investment and trade in energy commodities, recognize resource development in North America as a policy priority, and reform regulatory practices to facilitate responsible, market-driven resource activity. The new strategy should also ensure competitive tax and royalty regimes as well as consistent and compatible environmental policies that eliminate layering and duplication and are competitive among the various jurisdictions. It should also recognize the continental and global nature of energy supply and the increasing interdependence of the partner nations' economies, encourage research and development, and ensure co-ordinated action on frontier natural gas development within a framework of inter-jurisdictional cooperation. Overall, the document is a thorough, credible presentation of the first principles of the oil and gas markets and an important first step towards influencing energy policy on a continental scale. 2 maps, 5 figs
