    The coal world experienced a true upheaval in the past five years World coal consumption went up 28 % between 2000 and 2005, as a result of the strong growth in Chinese demand. The growth should continue in the coming years: electrical plant builders' orders are mainly for coal. The regained interest in coal is based on the constraints experienced by competing energies (increase in oil and natural gas prices, geopolitical uncertainties, supply difficulties) and by the abundant reserves of coal in the world and the competitiveness of its price. The strong growth in world coal demand comes with a change in rules governing steam coal trading. While long term bilateral agreements were most common until the late nineties, there has been a true revolution in coal marketing since 2000: spot contracts, stock exchange emergence and futures contracts, price indexes. In a few years, the steam coal market has become a true commodities market, overtaking many more goods. The price of coal has also gone through strong variations since 2003. Whereas the price had been stable for decades, in 2004 the strong increase in China' s demand for coal and iron ore resulting in transport shortage, caused a strong increase in CAF coal prices. Since then, prices have gone down, but remain higher than the Eighties and Nineties levels. In spite of the increase, coal remains available at more competitive prices than its competing energies.

    Wood Mackenzie operates coal consulting offices in several cities around the world and is the number one consulting company in terms of global coal coverage. The company offers a unique mine-by-mine research methodology, and owns a proprietary modeling system for coal and power market forecasting. This presentation provided an overview of global thermal markets as well as recent market trends. Seaborne markets have an impact on price far greater than the volume of trade would imply. Research has also demonstrated that the global thermal coal market is divided between the Pacific and Atlantic Basins. The current status of several major coal exporting countries such as Canada, the United States, Venezuela, Colombia, Indonesia, Australia, China, South Africa, and Russia was displayed in an illustration. The presentation included several graphs indicating that the seaborne thermal coal market is highly concentrated; traditional coal flow and pricing trends shift as Asian demand growth and supply constraints lead to chronic under supply; coal prices have risen to historic highs in recent times; and, the Asian power sector demand is a major driver of future growth. The correlation between oil and gas markets to thermal coal was illustrated along with two scenarios of coal use in the United States in a carbon-constrained world. The impact of carbon legislation on coal demand from selected coal regions in the United States was also discussed. Wood Mackenzie forecasts a very strong growth in global thermal coal demand, driven largely by emerging Asian economies. tabs., figs

  4. US and world coal trade

    Stevens, B

    1988-07-01

    This paper reviews the US's coal trade with other countries in the world. Despite being pressed to support domestic coal producers, US utilities are looking towards Colombia for more of their supplies. Whilst the amount of Colombian coal imported into the US is small, it is a combination of this and coal imported from Australia, Canada and China which is causing concern. Studies indicate that the volume of coal imported into the US may rise to 3 Mt/year within three years. Coal exports may suffer if Brazil bans the import of significant quantities of US coking coal in retaliation against American trade sanctions against Brazilian computer import barriers. Also, Romania is expected to impose tariffs on US imports which will have an impact on US coal exported to Romania. US remains the top coal exporter to the European Communities but its lead was cut back due to a big rise of Australian export. A portion of EC market has also been lost to the USSR and Poland. Meanwhile, Japan is resisting buying US's steam coal because it is too expensive.

  5. Development of coal international trade

    Energy Technology Data Exchange (ETDEWEB)

    1983-11-01

    Most of the coal produced today is still for domestic consumption but international trade will grow in the future. This development requires investments and time for the realization of terminals, means of transport and preparation. Problems of land and sea transport and their influence on cost are examined. Environmental problems are briefly evolved. Charges, ship size, capacity are given for 1983/84 and estimated for 1987/90 in tables for main exporting countries (Australia, Canada, South Africa, USA and South America) and for importing European countries.

  6. The future of coal trading. Part 1: obstacles to coal trading

    International Nuclear Information System (INIS)

    Schafer, W.; Vaninetti, J.

    1998-01-01

    'Trading' as used in this article means routine buying and selling of futures contracts or options and other derivatives of future contracts. The variable nature of coal, lack of liquidity, and the coal industry's understanding and acceptance of commodity trading concepts are identified as three major barriers to successful trading of a coal futures contract. The article discusses these obstacles

  8. Coal refuse reclamation project

    Energy Technology Data Exchange (ETDEWEB)

    Zellmer, S.D.

    1979-04-06

    A 13.8 ha abandoned coal refuse site in southwestern Illinois was reclaimed by recontouring the refuse material and covering it with a minimum 30 cm of soil. The reclamation procedure included determination of the site's final land use, collection of preconstruction environmental data, and development and implementation of engineering plans. The project is demonstrating methods that can be used to reclaim abandoned coal refuse sites, and a multidisciplinary approach is being used to evaluate postconstruction environmental and economic effects of the reclamation effort. Surface water quality has shown significant improvement and plant cover is becoming established on the site. Soil microbial populations are developing and wildlife habitats are forming. The economic value of the site and adjacent properties has increased substantially and the area's aesthetic value has been enhanced. This project is providing valuable design data for future reclamation efforts of this type.

  9. Global Coal Trade. From Tightness to Oversupply

    International Nuclear Information System (INIS)

    Cornot-Gandolphe, Sylvie

    2013-01-01

    Over the past four years, international coal trade has been reshaped by China's surging imports. China, which was still a net exporter in 2008, became the world's first coal importer in 2011, taking over the position that Japan has occupied for three decades. Its imports have continued their rising trend and reached a record level in 2012, despite the country's economic slowdown. China imported 289 million tons of coal in 2012, up 30% over 2011. It now accounts for 23% of global imports. Although China is the world's largest coal producer, several factors have contributed to the sudden rise in its imports, including the higher cost of domestic coal relative to international prices and bottlenecks in transporting domestic coal to south-eastern provinces. More recently, another event shook the international coal business: the United States have been back on the market. The collapse of U.S. gas prices, to $4/million Btu in 2011 and even $2.75/million Btu in 2012, linked with the 'shale gas revolution', has made coal uncompetitive in the electricity sector, its main outlet on the U.S. market. U.S. coal demand dropped 4% in 2011 and 11% in 2012. The reduction in domestic demand has forced U.S. miners to look for overseas outlets. Their exports surged by 31% in 2011 and 16% in 2012. They reached 112 million tons in 2012, more than twice the level of 2009. The United States, which almost disappeared from the international steam coal market in the 2000's, have regained a larger share of the total coal export market, 9% in 2012, against 6% in 2009. These developments, although not directly linked, have a huge impact on the global market and pricing of coal. Chinese imports have helped the market to quickly recover from its low level of 2008-2009. The speed and magnitude of China's coal imports even shifts the market from a sluggish to a tight situation. Prices started to rise after their collapse in the second half of 2008 caused by the economic and financial crisis

    2012-05-15

    In recent years, there has been a convergence of international trade with traditional domestic markets, with import increasing into many coal producing regions, the influence of trade on domestic markets has been twofold. Firstly, imported coal displaces domestic production, and in doing so, secondly international price trends may drive prices of what remains of the indigenous market for coal. While international trade does not provide any additional benefits in terms of reduced CO2 at a coal-fired power stations, importing coal provides many benefits, such as cost savings, improved coal quality, enhanced supply diversity, and often fills a gap which is left where domestic supply is unable to fulfil. This report examines the various factors that have led to rise in popularity of seaborne-traded coal, and seeks to discuss the future of domestically produced coal in some of the major coal markets of the world.

  14. The coal question that emissions trading has not answered

    International Nuclear Information System (INIS)

    Pearse, Rebecca

    2016-01-01

    Can emissions trading assist with the task of placing a limit on coal production and consumption in Australia? This paper outlines a critical political economy perspective on coal and a flagship ‘market mechanism’ for emissions reduction. The prospects for an effective emissions trading scheme in coal-dominated economies are considered in light of its theoretical justifications as well as recent attempts to price carbon in Australia. Emissions trading is a weak instrument that does not address real-world failures of coal governance. At their theoretical best, carbon prices produce marginal changes to the cost structure of production. In practice, the Australian case demonstrates emissions trading is an attempt to displace the emissions reduction task away from coal, through compensation arrangements and offsetting. In light of the urgent need to rapidly reduce global emissions, direct regulation and democratisation of coal production and consumption should be flagship climate policy. - Highlights: • Emissions trading schemes (ETS) are weak instruments for placing a limit on coal. • Pre-existing failures of coal governance cannot be addressed by emissions trading. • Considerable transfers of public wealth to coal companies occurred as part of the Australian ETS. • Carbon offset arrangements spatially displace responsibility for reducing emissions away from coal.

  15. Clean Coal Diesel Demonstration Project

    2006-10-31

    A Clean Coal Diesel project was undertaken to demonstrate a new Clean Coal Technology that offers technical, economic and environmental advantages over conventional power generating methods. This innovative technology (developed to the prototype stage in an earlier DOE project completed in 1992) enables utilization of pre-processed clean coal fuel in large-bore, medium-speed, diesel engines. The diesel engines are conventional modern engines in many respects, except they are specially fitted with hardened parts to be compatible with the traces of abrasive ash in the coal-slurry fuel. Industrial and Municipal power generating applications in the 10 to 100 megawatt size range are the target applications. There are hundreds of such reciprocating engine power-plants operating throughout the world today on natural gas and/or heavy fuel oil.

    The NOXSO Clean Coal Project will consist of designing, constructing, and operating a commercial-scale flue-gas cleanup system utilizing the NOXSO Process. The process is a waste-free, dry, post-combustion flue-gas treatment technology which uses a regenerable sorbent to simultaneously adsorb sulfur dioxide (SO{sub 2}) and nitrogen oxides (NO{sub x}) from flue gas from coal-fired boilers. The NOXSO plant will be constructed at Alcoa Generating Corporation`s (AGC) Warrick Power Plant near Evansville, Indiana and will treat all the flue gas from the 150-MW Unit 2 boiler. The NOXSO plant is being designed to remove 98% of the SO{sub 2} and 75% of the NO{sub x} when the boiler is fired with 3.4 weight percent sulfur, southern-Indiana coal. The NOXSO plant by-product will be elemental sulfur. The elemental sulfur will be shipped to Olin Corporation`s Charleston, Tennessee facility for additional processing. As part of the project, a liquid SO{sub 2} plant has been constructed at this facility to convert the sulfur into liquid SO{sub 2}. The project utilizes a unique burn-in-oxygen process in which the elemental sulfur is oxidized to SO{sub 2} in a stream of compressed oxygen. The SO{sub 2} vapor will then be cooled and condensed. The burn-in-oxygen process is simpler and more environmentally friendly than conventional technologies. The liquid SO{sub 2} plant produces 99.99% pure SO{sub 2} for use at Olin`s facilities. The $82.8 million project is co-funded by the US Department of Energy (DOE) under Round III of the Clean Coal Technology program. The DOE manages the project through the Pittsburgh Energy Technology Center (PETC).

  17. The evolution of hard coal trade in the Pacific market

    International Nuclear Information System (INIS)

    Ekawan, Rudianto; Duchene, Michel; Goetz, Damien

    2006-01-01

    This article analyses the evolution of hard coal trade in the Asia Pacific region, known as the Pacific market, from the 1980s to the present years. It investigates the development of the trade pattern, the nature of contracts, the price setting, the supply demand and the future of trade. Over the last two decades, the international trade in the Pacific market has achieved dramatic increases in coal commerce. This achievement is due to strong demand in Japan and North-east Asian countries and progressive coal export in Australia and Indonesia. It is likely that this market will continue to expand and become a more important market in replacing the Atlantic market. In this market, historically, long-term supply contracts were usual and concluded between producer and consumer. Even recently, there are still annual contracts, but with a small number of deals. In contrast, spot transactions are now becoming more important. Previously, Japan had been influential in price setting by establishing 'a benchmark price' with Australian coal suppliers. Afterward 'a reference price' was becoming a trend. Nowadays, spot price indices, such as the Barlow Jonker, the Barlow Jonker ACR and globalCOAL, have become important to set the price. The Pacific market growth is not without problems. The exporter countries, particularly Australia and Indonesia, have some challenges that if they are not resolved at present, it would implicate the performance of the coal trade

    The New England Power Company (NEPCO) recently converted Brayton Point Power Station Units 1, 2, and 3 from oil to coal. The coal conversion project is the largest coal conversion project in the nation to date. Stone and Webster Engineering Corporation (SWEC) was hired as the engineer/constructor for the project. Units 1 and 2 are 250-MW Combustion Engineering boilers, and Unit 3 is a 650-MW Babcock and Wilcox boiler. All three units were originally designed to burn pulverized coal but were converted to oil during the years of low oil prices. Studies performed by NEPCO and SWEC indicated that the areas discussed in the following paragraphs required upgrading before the units could efficiently burn coal and meet Federal and State environmental requirements. All units have been converted and are operating. This paper discusses design modifications required to burn coal, startup, and initial operating problems, and solutions.

    2000-09-01

    The close of 1999 marked the completion of the Demonstration Period of the Wabash River Coal Gasification Repowering Project. This Final Report summarizes the engineering and construction phases and details the learning experiences from the first four years of commercial operation that made up the Demonstration Period under Department of Energy (DOE) Cooperative Agreement DE-FC21-92MC29310. This 262 MWe project is a joint venture of Global Energy Inc. (Global acquired Destec Energy's gasification assets from Dynegy in 1999) and PSI Energy, a part of Cinergy Corp. The Joint Venture was formed to participate in the Department of Energy's Clean Coal Technology (CCT) program and to demonstrate coal gasification repowering of an existing generating unit impacted by the Clean Air Act Amendments. The participants jointly developed, separately designed, constructed, own, and are now operating an integrated coal gasification combined-cycle power plant, using Global Energy's E-Gas{trademark} technology (E-Gas{trademark} is the name given to the former Destec technology developed by Dow, Destec, and Dynegy). The E-Gas{trademark} process is integrated with a new General Electric 7FA combustion turbine generator and a heat recovery steam generator in the repowering of a 1950's-vintage Westinghouse steam turbine generator using some pre-existing coal handling facilities, interconnections, and other auxiliaries. The gasification facility utilizes local high sulfur coals (up to 5.9% sulfur) and produces synthetic gas (syngas), sulfur and slag by-products. The Project has the distinction of being the largest single train coal gasification combined-cycle plant in the Western Hemisphere and is the cleanest coal-fired plant of any type in the world. The Project was the first of the CCT integrated gasification combined-cycle (IGCC) projects to achieve commercial operation.

    The goal of the U.S. Department of Energy's (DOE) Clean Coal Technology (CCT) Program is to provide the energy marketplace with advanced, more efficient, and environmentally responsible coal utilization options by conducting demonstrations of new technologies. These demonstration projects are intended to establish the commercial feasibility of promising advanced coal technologies that have been developed to a level at which they are ready for demonstration testing under commercial conditions. This document serves as a DOE post-project assessment (PPA) of the Healy Clean Coal Project (HCCP), selected under Round III of the CCT Program, and described in a Report to Congress (U.S. Department of Energy, 1991). The desire to demonstrate an innovative power plant that integrates an advanced slagging combustor, a heat recovery system, and both high- and low-temperature emissions control processes prompted the Alaska Industrial Development and Export Authority (AIDEA) to submit a proposal for this project. In April 1991, AIDEA entered into a cooperative agreement with DOE to conduct this project. Other team members included Golden Valley Electric Association (GVEA), host and operator; Usibelli Coal Mine, Inc., coal supplier; TRW, Inc., Space & Technology Division, combustor technology provider; Stone & Webster Engineering Corp. (S&W), engineer; Babcock & Wilcox Company (which acquired the assets of Joy Environmental Technologies, Inc.), supplier of the spray dryer absorber technology; and Steigers Corporation, provider of environmental and permitting support. Foster Wheeler Energy Corporation supplied the boiler. GVEA provided oversight of the design and provided operators during demonstration testing. The project was sited adjacent to GVEA's Healy Unit No. 1 in Healy, Alaska. The objective of this CCT project was to demonstrate the ability of the TRW Clean Coal Combustion System to operate on a blend of run-of-mine (ROM) coal and waste coal, while meeting strict

    2014-11-01

    Full Text Available In 1869, with the opening of the Suez Canal, world trade entered a new era of development. The commercial routes linking the Far East to the western countries were shortened considerably as compared to the maritime corridor around the Cape of Good Hope. In 1914, the opening of the Panama Canal sealed the new deal in world trade, opening for business the shortest commercial routes around the world. After 145 years from the inauguration of the Suez Canal, world trade is on the eve of a new expansion. Two major projects: the expansion of both the Suez and Panama canals, planned to be completed in the next two years, will double their transit capacity. This paper does a comparative analysis of these two strategic projects, underlining the main benefits for Egypt, Panama and world trade, based on the available statistical data, reports and literature in the field.

    2005-03-30

    As part of the U.S. Department of Energy (DoE) initiative to improve the efficiency of coal-fired power plants and reduce the pollution generated by these facilities, DOE has funded the High-Pressure Coal Combustion Kinetics (HPCCK) Projects. A series of laboratory experiments were conducted on selected pulverized coals at elevated pressures with the specific goals to provide new data for pressurized coal combustion that will help extend to high pressure and validate models for burnout, pollutant formation, and generate samples of solid combustion products for analyses to fill crucial gaps in knowledge of char morphology and fly ash formation. Two series of high-pressure coal combustion experiments were performed using SRI's pressurized radiant coal flow reactor. The first series of tests characterized the near burner flame zone (NBFZ). Three coals were tested, two high volatile bituminous (Pittsburgh No.8 and Illinois No.6), and one sub-bituminous (Powder River Basin), at pressures of 1, 2, and 3 MPa (10, 20, and 30 atm). The second series of experiments, which covered high-pressure burnout (HPBO) conditions, utilized a range of substantially longer combustion residence times to produce char burnout levels from 50% to 100%. The same three coals were tested at 1, 2, and 3 MPa, as well as at 0.2 MPa. Tests were also conducted on Pittsburgh No.8 coal in CO2 entrainment gas at 0.2, 1, and 2 MPa to begin establishing a database of experiments relevant to carbon sequestration techniques. The HPBO test series included use of an impactor-type particle sampler to measure the particle size distribution of fly ash produced under complete burnout conditions. The collected data have been interpreted with the help of CFD and detailed kinetics simulation to extend and validate devolatilization, char combustion and pollutant model at elevated pressure. A global NOX production sub-model has been proposed. The submodel reproduces the performance of the detailed chemical

    In recent years, there has been a convergence of international trade with traditional domestic markets. As imports continue to increase in many coal producing regions, the influence of trade on domestic markets has been twofold. Firstly, imported coal displaces domestic production and, secondly, international price trends may drive prices of what remains of the indigenous market for coal. While international trade does not provide any additional benefits in terms of reduced CO2 at coalfired power stations, importing coal provides many benefits, such as cost savings, improved coal quality, enhanced supply diversity, and often fills a gap which domestic supply is unable to fulfil. This report examines how coal markets have evolved over the decades with utilities and heavy industry moving away from their seemingly secure yet captive markets of domestic coal to procuring more supplies from the international market to satisfy the need of cost reduction and better and consistent quality of fuel product. The various factors that have led to a rise in popularity of seaborne traded coal, and the future of domestically produced coal in the Pacific market are discussed. This is in one of three reports which examine the changing trends in coal imports over the long term in three geographical regions: a global perspective, the Atlantic market and the Pacific market.

    Emissions Trading started within EU at the beginning of 2005. It caused substantial changes to the business environment of energy companies and energy intensive industry. The planning of Emissions Trading is a complicated process and companies will need consulting, IT systems and other services. Emissions Trading introduces a new factor of production emission allowances, which are tradable commodities. In future, Emissions Trading emissions, emission allowances and the prices of emission allowances have to be considered during the fuel purchasing and the energy production planning. And the best possible knowledge of the own emissions balance and market situation has a monetary value when trading emission allowances. Allocation of emission allowances has done in each country according to National Allocation Plan (NAP), accepted by EU. Finland itself and thus also the Finnish companies will be net buyers of emission allowances in long run. That means commonly that the Finnish companies have to buy more allowances meaning some extra costs to the companies. That's why it is very important to develop and provide to the companies an innovatory emissions planning, follow-up, management and reporting systems. With good emission balance management the extra costs of Emissions Trading will be as low as possible. In ECO2 project, Empower together with Power-Deriva, developed Expert services, Emissions Balance Management and Reporting services and Risk Management services for Emissions Trading and needed software and tools for these services.

    Johnson, C.J.

    1997-08-01

    The Workshop brought together experts from APEC economies to discuss important issues related to coal development, trade and consumption in the APEC region, with a focus on Indonesia. Papers ranged from broad regional coal-related issues to specific policy and contract terms. The host, Indonesia, was selected as the focus of the workshop because it: (a) has APEC's fastest growing electricity sector, (b) is in the process of switching from oil based electricity generation to coal and natural gas-based generation, (c) is among the fastest growing coal exporters in APEC, and (d) has a contract system for coal development that has been widely accepted by foreign investors. In addition, Indonesia is in the process of revising its coal policies, and might benefit from the timely discussions in this workshop. The papers presented in the workshop spanned the coal chain from coal resources and reserves, conversion technologies, economics and markets, legal and policy issues, to community and cultural concerns. Participants represented government, industry and academic interests, and provided perspectives of coal and technology suppliers, consumers, energy policy makers and legal experts

    Coal world production represents 3.5 billions of tons, plus 900 millions of tons of lignite. 50% of coal is used for power generation, 16% by steel making industry, 5% by cement plants, and 29% for space heating and by other industries like carbo-chemistry. Coal reserves are enormous, about 1000 billions of tons (i.e. 250 years of consumption with the present day rate) but their exploitation will be in competition with less costly and less polluting energy sources. This documents treats of all aspects of coal: origin, composition, calorific value, classification, resources, reserves, production, international trade, sectoral consumption, cost, retail price, safety aspects of coal mining, environmental impacts (solid and gaseous effluents), different technologies of coal-fired power plants and their relative efficiency, alternative solutions for the recovery of coal energy (fuel cells, liquefaction).

    Szpor, Aleksander

    2017-01-01

    This is one of the 6 country case-studies commissioned to collect experience on past coal transitions. The 6 countries are: Czech Republic, the Netherlands, Poland, Spain, UK, USA. Their role in the Coal Transitions project was to provide background information for a Synthesis Report for decision makers, and provide general lessons for national project teams to take into account in developing their coal transitions pathways for the future. The restructuring of the Polish coal sector is inextricably related to the democratic transformation which began in 1989. The economic dimension of the transformation is manifested in the shift from central planning to the free market. Although this process brought economic growth, it has had severe social costs. The main goals of the coal sector restructuring were to achieve its profitability and competitiveness on the global market. However, even with a very quick down-sizing of production and employment, which positively affected the mines' productivity, these goals were not achieved. Neither the profitability of the sector nor the sustainability of the labour restructuring were achieved. There were three main reasons for lack of success in this process. Firstly, the rapid changes of governments making impossible implementation of long term strategies and ensure implementation of market rules in the sector. Secondly, the pressure from trade unions on sustaining the status quo - state owed structure of mining companies, professional privileges and increasing salaries. Thirdly, the lack of sufficient incentives for retraining the miners and revitalising the areas exposed the most on the coal sector restructuring. Content: Introduction; Historical background; Structure of the coal and energy sector; Policies for the restructuring of the coal sector: Main actors in the process, Governmental programs, Instruments for easing the restructuring processes; Conclusions and lessons learnt

    Investigations in the joint research project `Microbial transformation of coal and coal relevant structures` supported by the Ministry of Education, Science, Research and Technology (BMBF) of the Federal Republic of Germany and coordinated by the DMT-Gesellschaft fuer Forschung und Pruefung mbH (DMT) are focussed on research and development of biotechnological coal conversion processes. Up to now investigations carried out in the project lead to a number of important results. During work on the project a great number of different microorganisms was found able to degrade or solubilize coal or lignite. Enzymatic as well as regulation mechanisms of the microbial depolymerization processes have been characterized successfully. (orig.)

  17. The impact of TTIP agreement on the European Union-United States coal trade potential

    2016-01-01

    Full Text Available The main aim of the paper is to assess the impact of currently negotiated TTIP agreement (Transatlantic Trade and Investment Partnership on the use of hard coal in the EU and the US. Hard coal is the most important fuel in global electricity generation. This also applies to the United States, a leading manufacturer and exporter of this energy source. The US coal is exported to the EU market. The article presents the estimated exports of hard coal from the US to the EU. Due to the fact that price has a major impact on the size of exports, the paper presents the estimated prices, including freight costs, of power coal for the analyzed scenarios. According to one scenario, the US and European prices will be equalized (including freight costs by 2020, while from 2025 on the comparative advantage and competitiveness of the US hard coal will decrease. Taking into account the fact that the export of coal from the United States is free from customs duties, the acceptance of TIPP should not affect the currently existing trade between the two continents and the amount of exported coal. Nevertheless, the question of hard coal economy cannot be separated from other sectors of the energy market, which can be significantly affected by the future agreement.

    The province of Saskatchewan experienced significant growth between 2005 and 2008. The growing economy included an abundance of different commodities and made Saskatchewan the newest hub for the latest technologies and investment. This report outlined the various opportunities in Saskatchewan for a coal to liquids plant and its technologies. The coal from southern Saskatchewan is generally lignite, which is found in the Ravenscrag Formation near the Big Muddy Badlands. The report discussed the Ravenscrag Formation as well as mining activity that was largely concentrated near Estevan and Bienfait in southeastern Saskatchewan, where Sherritt International operated two surface mines. The Coronach Poplar River Power Station, located 10 kilometres north of the Canada-United States border in southern Saskatchewan was also discussed. Population density, labour, land use, First Nations, and proximity to major centres were factors that were discussed. The programs that were identified included the Saskatchewan immigrant nominee program, an alternative program to the Canadian federal immigration program for those who want to come to Saskatchewan as a permanent resident of Canada; the Weyburn-Midale carbon dioxide project, the world's first carbon dioxide measuring, monitoring and verification initiative; and the Federated Co-op in Regina, a 100,000 barrel/day refinery located close to the Coronach area in Saskatchewan. Political climate, access to the electrical grid, access to water, access to major pipelines, access to rail lines, and access to highways were other topics that were presented. It was concluded that southern Saskatchewan had a broad range of opportunities for a coal to liquids plant. The area has numerous advantages including access to rail and pipelines. refs., tabs., figs., appendices.

    The Trade and Development Program (TDP), a U.S. Government agency, provides funding for US firms to carry out feasibility studies, consultancies, and other planning services related to major projects in developing countries. By providing assistance in project planning, TDP promotes economic development; at the same time, TDP helps US firms get involved in projects that offer significant export opportunities. TDP has programs throughout the developing world, including Central and Eastern Europe, and has recently been authorized to operate in the Newly Independent States (NIS) of the former Soviet Union. The vast size and population of this region, as well as its tremendous infrastructural and basic industrial needs, present new challenges to TDP. The basic TDP program is described below; it is likely to be modified somewhat to meet the specific requirements of the NIS

    The Wabash River Coal Gasification Repowering Project (WRCGRP), a joint venture between Destec Energy, Inc. and PSI Energy, Inc., began commercial operation in November of 1995. The Project, selected by the United States Department of Energy (DOE) under the Clean Coal Program (Round IV) represents the largest operating coal gasification combined cycle plant in the world. This Demonstration Project has allowed PSI Energy to repower a 1950`s vintage steam turbine and install a new syngas fired combustion turbine to provide 262 MW (net) of electricity in a clean, efficient manner in a commercial utility setting while utilizing locally mined high sulfur Indiana bituminous coal. In doing so, the Project is also demonstrating some novel technology while advancing the commercialization of integrated coal gasification combined cycle technology. This paper discusses the first year operation experience of the Wabash Project, focusing on the progress towards achievement of the demonstration objectives.

  1. Investment practices in Australian coal: the practice and profit of quasi-integration in the Australia-Japan coal trade

    International Nuclear Information System (INIS)

    Colley, Peter

    1997-01-01

    The Australian coal industry has frequently been described as a perpetual case of 'profitless prosperity'. Industry literature on the subject usually sources this problem to government charges on the industry and to labour costs. However, these alleged problems do not appear to have diminished the enthusiasm for new investment in the industry. This study argues that a more complete explanation must look at who is investing in the Australian coal industry, what the rationale for those investments is, how they are financed and what their specific profitability is. The particular examination made here is of the quasi-integration investment practices of Japanese trading, steel and power companies -easily the largest group of buyers in the international coal trade. The close co-operation between Japanese government and business in this strategic raw materials industry is documented, as are the methods of subsidised investment. An examination of the financial performance of these companies' Australian coal investments shows that the profitability of their investments is significantly below that of most other investors in Australian mining over a recent 5-year period. Taken together, there is significant support for the conclusion that a process of co-ordinated quasi-integration has taken place and that the principal aim of such investments has not been to make profits from coal-mining.

    1992-01-01

    After reviewing clean coal technologies currently under study in the United States, Australia, and Japan, under the current climate of global warming concerns, one concludes that some of these technologies might well be commercialised soon, especially if some kind of 'emission trading' regime is encouraged after the 1992 United Nations Conference on Environmental and Development (UNCED, Rio de Janeiro, Brazil, June 1992). Some alternative financing possibilities under various emission trading regimes are studied for a 'sample' technology to illustrate the issues involved in clean-coal technology penetration. It is concluded that a financial 'carbon saving credit' alone might prove sufficient to stimulate such penetration. (author)

    The aim of this DTI project is to establish good quality plant and rig data to demonstrate the effect of changing coal fineness on carbon burnout in a controlled manner, which can then be used to support computational fluid dynamics (CFD) and engineering models of the process. The modelling elements of the project were completed by Mitsui Babcock Energy Ltd., and validated using the data produced by the other partners. The full scale plant trials were successfully completed at Powergen's Kingsnorth Power Station and a full set of tests were also completed on Powergen's CTF. During these test both carbon-in-ash and NOx levels were seen to increase with increasing fuel particle size. Laboratory analysis of fly ash produced during the plant and rig trials revealed that only small differences in char morphology and reactivity could be detected in samples produced under significantly different operating conditions. Thermo Gravimetric Analysis was also undertaken on a range of PF size fractions collected form mills operating at different conditions. 3 refs., 13 figs., 1 tab.

  6. International coal trade: the evolution of a global market

    International Nuclear Information System (INIS)

    1998-01-01

    The international coal market has developed over the last 25 years to a mature stable market, largely free of government involvement. It is evident, however, that while the coal market is considered widely to be reliable and mature, there is only limited understanding of the way in which the market operates. Understanding energy market mechanisms is fundamental to encourage confidence in the continuing performance of liberalized markets. This publication seeks to address this need by providing a brief descriptive analysis of the operation of the coal market. The report draws attention to the considerable changes that have been experienced to date in the market, where freely operating market mechanisms have coped well. Further change is on the horizon. Coal demand in Europe is stagnating while growing rapidly in Asia. The once-dominant European market remains the region where price is formed but the Asian market is growing rapidly and becoming more flexible. Increasing competition for market share, low margins, and pressure on utilities to reduce costs as electricity markets are liberalized, will continue to stimulate productivity improvement and may lead to innovations in marketing to cope with stable real prices, high transport, and transaction costs

    The goal of the U.S. Department of Energy (DOE) Clean Coal Technology Program (CCT) is to furnish the energy marketplace with a number of advanced, more efficient, and environmentally responsible coal utilization technologies through demonstration projects. These projects seek to establish the commercial feasibility of the most promising advanced coal technologies that have developed beyond the proof-of-concept stage. This document serves as a DOE post-project assessment (PPA) of a project selected in CCT Round IV, the Wabash River Coal Gasification Repowering (WRCGR) Project, as described in a Report to Congress (U.S. Department of Energy 1992). Repowering consists of replacing an existing coal-fired boiler with one or more clean coal technologies to achieve significantly improved environmental performance. The desire to demonstrate utility repowering with a two-stage, pressurized, oxygen-blown, entrained-flow, integrated gasification combined-cycle (IGCC) system prompted Destec Energy, Inc., and PSI Energy, Inc., to form a joint venture and submit a proposal for this project. In July 1992, the Wabash River Coal Gasification Repowering Project Joint Venture (WRCGRPJV, the Participant) entered into a cooperative agreement with DOE to conduct this project. The project was sited at PSI Energy's Wabash River Generating Station, located in West Terre Haute, Indiana. The purpose of this CCT project was to demonstrate IGCC repowering using a Destec gasifier and to assess long-term reliability, availability, and maintainability of the system at a fully commercial scale. DOE provided 50 percent of the total project funding (for capital and operating costs during the demonstration period) of$438 million

    WR Grace and Co. are planning a feasibility study for a plant to produce 5000 tons/day of methanol and 6000 tons/day of carbon dioxide from captive coal reserves in Colorado. The study will be performed by Energy Transition Co. (ETCo). The producers would be used for pipeline transmission of pulverised coal, probably to California. At the destination the coal would go to a power station, the methanol to a gas turbine and the carbon dioxide to an oil producer for tertiary recovery.

  9. The outlook for the U.S. coal industry and U.S.-Japanese coal trade

    Ellerman, A.D.

    1988-01-01

    The U.S. coal industry is stable and efficient, and in good position to respond to any increase in export demand over the next ten years. After the 1973 and 1978--79 oil price increases and the resulting growth in world demand for coal, the industry responded with extensive investment in coal mines; the transportation industry similarly made large investments in coal handling equipment and port facilities. However, as a result of the expansion in world production facilities and the less than anticipated growth in coal demand, the United States now has excess capacity---in the mining, transport and port terminal industries. The coal industry's large capital investments, followed by cost cutting improvements in response to excess capacity, have paid off in greatly increased productivity. Between its low point in 1978, and 1985, average tons per miner-hour grew by 55 percent, or at an average annual rate of 6.4 percent. This gain has been passed on to coal customers in the form of lower prices. Between 1976 and 1985, FOB mine prices in constant dollars declined by 26.9 percent, or at a rate of 3.4 percent per year; the trend continued in 1986 with an additional 4.8 percent price decline

    A test burn of two Alaskan coals was conducted at TRW`s Cleveland test facility in support of the Healy Clean Coal Project, as part of Clean Coal Technology III Program in which a new power plant will be constructed using a TRW Coal Combustion System. This system features ash slagging technology combined with NO{sub x} and SO{sub x} control. The tests, funded by the Alaska Industrial Development and Export Authority (AIDEA) and TRW, were conducted to verify that the candidate Healy station coals could be successfully fired in the TRW coal combustor, to provide data required for scale-up to the utility project size requirements, and to produce sufficient flash-calcined material (FCM) for spray dryer tests to be conducted by Joy/NIRO. The tests demonstrated that both coals are viable candidates for the project, provided the data required for scale-up, and produced the FCM material. This report describes the modifications to the test facility which were required for the test burn, the tests run, and the results of the tests.

    The Interagency Coal Export Task Force was formed in the Spring of 1980 at the direction of the President, in support of the international efforts of the United States, encouraging the use of coal. Its purpose was to report on possible courses of action to increase United States steam coal exports in a manner consistent with other national policies, including our commitment to environmental protection. The Task Force assembled existing data, developed significant new information regarding the international coal market and undertook analyses of apparent problems underlying coal exports. The Task Force contributed to a public awareness of the fact that increased coal exports will serve both the domestic and international interests of the United States. Based upon extensive, independent field studies in Europe and the Far East, the Task Force concludes that there will be significant growth in world demand for steam coal. Such growth has already begun, has contributed to the almost seven-fold increase in United States overseas steam coal exports for 1990 over 1979, and is expected to continue beyond the end of this century. The growth in world steam coal trade projected in the report does not guarantee United States coal exporters a large or expanding share of the market. The United States' role depends on the buying strategies of the consuming countries, the policies and prices of competing exporters, and the actions taken by the United States to maintain reasonable prices, prompt delivery and dependable quality. Projections of United States steam coal exports, therefore, rest upon a number of highly uncertain factors which are discussed in some detail.

The CCT Demonstration Program is a government and industry cofunded technology development effort to demonstrate a new generation of innovative coal utilization processes in a series of commercial-scale facilities. The ENCOAL{reg_sign} Corporation, a wholly-owned subsidiary of Bluegrass Coal Development Company (formerly SMC Mining Company), which is a subsidiary of Ziegler Coal Holding Company, submitted an application to the DOE in August 1989, soliciting joint funding of the project in the third round of the CCT Program. The project was selected by DOE in December 1989, and the Cooperative Agreement (CA) was approved in September 1990. Construction, commissioning, and start-up of the ENCOAL{reg_sign} mild coal gasification facility was completed in June 1992. In October 1994, ENCOAL{reg_sign} was granted a two-year extension of the CA with the DOE, that carried through to September 17, 1996. ENCOAL{reg_sign} was then granted a six-month, no-cost extension through March 17, 1997. Overall, DOE provided 50 percent of the total project cost of $90,664,000. ENCOAL{reg_sign} operated the 1,000-ton-per-day mild gasification demonstration plant at Triton Coal Company's Buckskin Mine near Gillette, Wyoming, for over four years. The process, using Liquids From Coal (LFC{trademark}) technology originally developed by SMC Mining Company and SGI International, utilizes low-sulfur Powder River Basin (PRB) coal to produce two new fuels, Process-Derived Fuel (PDF{trademark}) and Coal-Derived Liquids (CDL{trademark}). The products, as alternative fuel sources, are capable of significantly lowering current sulfur emissions at industrial and utility boiler sites throughout the nation thus reducing pollutants causing acid rain.

This document serves as a DOE post-project assessment (PPA) of a project selected in CCT Round IV, the Wabash River Coal Gasification Repowering (WRCGR) Project, as described in a Report to Congress (U.S. Department of Energy 1992). Repowering consists of replacing an existing coal-fired boiler with one or more clean coal technologies to achieve significantly improved environmental performance. The desire to demonstrate utility repowering with a two-stage, pressurized, oxygen-blown, entrained-flow, integrated gasification combined-cycle (IGCC) system prompted Destec Energy, Inc., and PSI Energy, Inc., to form a joint venture and submit a proposal for this project. In July 1992, the Wabash River Coal Gasification Repowering Project Joint Venture (WRCGRPJV, the Participant) entered into a cooperative agreement with DOE to conduct this project. The project was sited at PSI Energy's Wabash River Generating Station, located in West Terre Haute, Indiana. The purpose of this CCT project was to demonstrate IGCC repowering using a Destec gasifier and to assess long-term reliability, availability, and maintainability of the system at a fully commercial scale. DOE provided 50 percent of the total project funding (for capital and operating costs during the demonstration period) of$438 million. Construction for the demonstration project was started in July 1993. Pre-operational tests were initiated in August 1995, and construction was completed in November 1995. Commercial operation began in November 1995, and the demonstration period was completed in December

    The proposed project would result in a combined-cycle power plant with lower emissions and higher efficiency than most existing coal-fired power plants of comparable size. The net plant heat rate (energy content of the fuel input per useable electrical generation output; i.e., Btu/kilowatt hour) for the new repowered unit would be a 21% improvement over the existing unit, while reducing SO 2 emissions by greater than 90% and limiting NO x emissions by greater than 85% over that produced by conventional coal-fired boilers. The technology, which relies on gasified coal, is capable of producing as much as 25% more electricity from a given amount of coal than today's conventional coal-burning methods. Besides having the positive environmental benefit of producing less pollutants per unit of power generated, the higher overall efficiency of the proposed CGCC project encourages greater utilization to meet base load requirements in order to realize the associated economic benefits. This greater utilization (i.e., increased capacity factor) of a cleaner operating plant has global environmental benefits in that it is likely that such power would replace power currently being produced by less efficient plants emitting a greater volume of pollutants per unit of power generated

    This report describes the tasks, which Bergbau-Forschung has carried out in the field of steam gasification of coal in cooperation with partners and contractors during the reference phase of the project. On the basis of the status achieved to date it can be stated, that the mode of operation of the gas-generator developed including the direct feeding of caking high volatile coal is technically feasible. Moreover through-put can be improved by 65% at minimum by using catalysts. On the whole industrial application of steam gasification - WKV - using nuclear process heat stays attractive compared with other gasification processes. Not only coal is conserved but also the costs of the gas manufactured are favourable. As confirmed by recent economic calculations these are 20 to 25% lower. (orig.) [de

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

    This Environmental Monitoring Plan (EMP) provides the mechanism to evaluate the integrated coal combustion/emission control system being demonstrated by the Healy Clean Coal Project (HCCP) as part-of the third solicitation of the US Department of Energy (DOE) Clean Coal Technology Demonstration Program (CCT-III). The EMP monitoring is intended to satisfy two objectives: (1) to develop the information base necessary for identification, assessment, and mitigation of potential environmental problems arising from replication of the technology and (2) to identify and quantify project-specific and site-specific environmental impacts predicted in the National Environmental Policy Act (NEPA) documents (Environmental Impact Statement and Record of Decision). The EMP contains a description of the background and history of development of the project technologies and defines the processes that will take place in the combustion and spray dryer absorber systems, including the formation of flash-calcined material (FCM) and its use in sulfur dioxide (SO{sub 2}) removal from the flue gases. It also contains a description of the existing environmental resources of the project area. The EMP includes two types of environmental monitoring that are to be used to demonstrate the technologies of the HCCP: compliance monitoring and supplemental monitoring. Compliance monitoring activities include air emissions, wastewater effluents, and visibility. Monitoring of these resources provide the data necessary to demonstrate that the power plant can operate under the required state and federal statutes, regulations, and permit requirements.

  6. Managing trade-offs in landscape restoration and revegetation projects.

    Landscape restoration projects often have multiple and disparate conservation, resource enhancement, and sometimes economic objectives, since projects that seek to meet more than one objective tend to be viewed more positively by funding agencies and the community. The degree to which there are trade-offs among desired objectives is an important variable for decision makers, yet this is rarely explicitly considered. In particular, the existence of ecological thresholds has important implications for decision-making at both the project level and the regional level. We develop a model of the possibilities and choices for an agency seeking to achieve two environmental objectives in a region through revegetation of a number of sites. A graphical model of the production possibilities sets for a single revegetation project is developed, and different trade-off relationships are discussed and illustrated. Then the model is used to demonstrate the possibilities for managing all such projects within a region. We show that, where there are thresholds in the trade-off relationship between two objectives, specialization (single- or dominant-objective projects) should be considered. This is illustrated using a case study in which revegetation is used to meet avian biodiversity and salinity mitigation objectives. We conclude that where there are sufficient scientific data, explicit consideration of different types of trade-offs can assist in making decisions about the most efficient mix and type of projects to better achieve a range of objectives within a region.

    This is one of the 6 country case-studies commissioned to collect experience on past coal transitions. The 6 countries are: Czech Republic, the Netherlands, Poland, Spain, UK, USA. Their role in the Coal Transitions project was to provide background information for a Synthesis Report for decision makers, and provide general lessons for national project teams to take into account in developing their coal transitions pathways for the future. Over the past decade, the US started to cut down the production and the use of coal, which was affected by unfavorable market dynamics and changing federal regulatory environment. Even before the shale gas revolution and uptake of renewables diminish the use of coal in power generation, coal communities were struggling to meet ends. The regional cost differences between producing states, such as the Appalachian and the Powder River Basins, indicates that coal-impacted communities and workers have lived through the impacts of coal transition at varying magnitudes and time periods. In the period between 2014 and 2016, we have seen the crash of major US coal companies due to declining demand for US coal domestically and internationally. Furthermore, Obama administration's climate change policies negatively impacted coal-fired power plants with additional GHG emission requirements, contributing to declining domestic demand for coal. Combined with market downturn, US coal producers already struggle to pay for high operational costs and legal liabilities under bankruptcy conditions. With under-funded state budgets, coal states are also grappling with financial exposure resulting from pension, health care and reclamation liabilities of bankrupt coal companies. In 2016, former President Obama announced the Power Plus Plan to aid coal-impacted communities and workers to prepare for a low carbon future. The federal budget plan targeted diversification of local economies, funding of health and pension funds of miners and retraining for

    The need for a so-called 'just transition' is acknowledged, away from carbon intensive activities, such as coal production and use. But what might a just transition look like in practice? What specific risks need to be managed and what are the best approaches to managing them? There is an urgent need to develop a deeper understanding of these issues. It is to this need that this report tries to respond. It provides a summary of lessons from six historical case studies of regional coal mining transitions that have occurred or are ongoing in Europe and the United States in recent decades. These case studies and this report were developed as part of a broader project led by IDDRI and Climate Strategies, entitled 'Coal Transitions: Research and Dialogue on the Future of Coal'. This project seeks to utilise these historical lessons to facilitate the development of feasible coal transition scenarios in large coal producing countries today'

    The Central Arkansas Energy Project has as its objective the conversion of coal in a central location to a more readily usable energy source, medium Btu gas (MBG), for use at dispersed locations as fuel for power production and steam generation, or as a feedstock for chemical processing. The project elements consist of a gasification facility to produce MBG from coal, a pipeline to supply the MBG to the dispersed sites. The end of line users investigated were the repowering or refueling of an existing Arkansas Power and Light Co. Generating station, an ammonia plant, and a combined cycle cogeneration facility for the production of steam and electricity. Preliminary design of the gasification plant including process engineering design bases, process flow diagrams, utility requirements, system description, project engineering design, equipment specifications, plot plan and section plot plans, preliminary piping and instrument diagrams, and facilities requirements. Financial analyses and sensitivities are determined. Design and construction schedules and manpower loadings are developed. It is concluded that the project is technically feasible, but the financial soundness is difficult to project due to uncertainty in energy markets of competing fuels.

    The calorific value of coal is an important factor for the economic operation of coal-fired power plant. However, calorific value is tremendous difference between the different coal, and even if coal is from the same mine. Restricted by the coal market, most of coal fired power plants can not burn the designed-coal by now in China. The properties of coal as received are changing so frequently that pulverized coal firing is always with the unexpected condition. Therefore, the researches on the...

    2003-01-01

    In this paper, the gasification conditions, the gasifier structure, the measuring system and the gasification rationale of a pilot project experiment of underground coal gasification (UCG) in the Liuzhuang Colliery, Tangshan, are illustrated. The technique of two-phase underground coal gasification is proposed. The detection of the moving speed and the length of the gasification working face is made using radon probing technology. An analysis of the experiment results indicates that the output of air gas is 3000 m 3 /h with a heating value of about 4.18 MJ/m 3 , while the output of water gas is 2000 m 3 /h with a heating value of over 11.00 MJ/m 3 , of which H 2 content is above 40% with a maximum of 71.68%. The cyclical time of two-phase underground gasification is 16 h, with 8 h for each phase. This prolongs the time when the high-heating value gas is produced. The moving speed of the gasification working face in two alternative gasifiers is identified, i.e. 0.204 and 0.487 m/d, respectively. The success of the pilot project experiment of the underground gasification reveals the strides that have been made toward the commercialization of the UCG in China. It also further justifies the reasonability and feasibility of the new technology of long channel, big section, two-phase underground gasification. A conclusion is also drawn that the technology of the pilot project experiment can be popularized in old and discarded coal mines

    concerns about climate change problem. Carbon Capture and Storage (CCS) is being considered as a promising carbon mitigation technology, especially for large point sources such as coal power plants. Gasification of coal helps in better utilization of this resource offering multiple advantages such as pollution prevention, product flexibility (syngas and hydrogen) and higher efficiency (combined cycle). It also enables the capture of CO2 prior to the combustion, from the fuel gas mixture, at relatively lesser cost as compared to the post-combustion CO2 capture. CCS in gasification projects is considered as a promising technology for cost-effective carbon mitigation. Although many projects (power and non-power) have been announced internationally, very few large-scale projects have actually come up. This paper looks at the various aspects of CCS applications in gasification projects, including the technical feasibility and economic viability and discusses an Indian perspective. Impacts of including CCS in gasification projects (e.g. IGCC plants) have been assessed using a simulation tool. Integrated Environmental Control Model (IECM) - a modelling framework to simulate power plants - has been used to estimate the implications of adding CCS units in IGCC plants, on their performance and costs.

    Despite efforts to improve energy effi-ciency and increase the usage of renewable energy carriers, fossil fuels and nuclear energy will continue to be important sources of global energy supply for the coming decades. Present global oil and gas supply is characterized by a concentration of production in a few world areas, mainly the Middle East and the Former Soviet Union, and a transport from these regions to the industrialized countries. Depletion of conventional reserves, especially oil, in combination with a surge for energy in emerging economies, as China and India, how-ever, is expected to change this picture in the future: unconventional resources in other world regions may be exploited to cover the surge energy demand, infrastructure for energy transport along new routes may have to be established. To provide a data base for such ques-tions, this report gives an overview of the current global resource situation for coal, natural gas, oil and uranium. In the first part, an assessment of the con-ventional and unconventional reserves and resources as well as their supply costs is given for the different regions of the world. The second part describes the current energy trade infrastructure between world regions and estimates the costs for existing and new trade links between these regions. (orig.)

    The survey purpose is to identify availability of coal resources for liquefaction in major coal producing countries in the Pacific basin area. Therefore, collection is carried out on such data as coal existing conditions, coal qualities, production quantities, and infrastructures on coal mines being operated and projects under development or investigation. Coal samples are collected in wide range and exhaustively unbiased to particular coal fields and mines to acquire data to perform selection and evaluation of coals that can be fed to coal liquefying plants. The present survey was intended to acquire fundamental data for the liquefying coal selection, such as coal existing conditions, natures, and infrastructures for the coal resources, taking up as the survey object countries the State of Alaska, U.S.A. and Indonesia. The coal types as the object of the survey are mainly sub-bituminous coal, and additionally brown coal and partly bituminous coal. The amount of coal deposit as the subject of the investigation is 100 million tons or more as the verified reserve. The subject areas cover coal mines in the State of Alaska, U.S.A. (Northern Alaska, Nenana, Beluga, and Matanuska coal fields), and Indonesia (the Sumatra and Kalimantan islands). The survey items are made up of 14 items (see the coal mine survey tables in JN0040851). (NEDO)

    This paper describes a UK Department of Trade and Industry-supported collaborative project entitled `The Effects of Coal Quality on Emission of Oxides of Nitrogen (NO{sub x}) and Carbon Burnout in Pulverised Coal-fired Utility Boilers`. The project involved extensive collaboration between the UK power generators, boiler and burner manufacturers and research groups in both industry and academia, together with several of the world`s leading computational fluid dynamics (CFD) `software houses`. The prime objectives of the project were to assess the relationship between NO{sub x} emissions and carbon burnout and to develop and validate predictive tools for assessing coals. Experimental work was carried out on various laboratory-scale apparatus and on single burner test facilities ranging from 160 kW{sub th} to 40 MW{sub th} in size and measurements were obtained from full-scale 500 MW{sub e} utility boiler trials. This data and basic coal data were then used to develop mathematical models to predict full-scale boiler performance with respect to NO{sub x} emissions and carbon-in-ash. Results showed good correlations for NO{sub x} and carbon burnout when comparing data from full-scale and large-scale rig trials. Laboratory-scale tests were found to be useful but the influence of burner aerodynamics was more difficult to quantify. Modelling showed that predicted NO{sub x} emissions were encouragingly close to measured emissions but predicting carbon burnout was less successful. 24 refs., 4 figs., 6 tabs.

    This is one of the 6 country case-studies commissioned to collect experience on past coal transitions. The 6 countries are: Czech Republic, the Netherlands, Poland, Spain, UK, USA. Their role in the Coal Transitions project was to provide background information for a Synthesis Report for decision makers, and provide general lessons for national project teams to take into account in developing their coal transitions pathways for the future. The UK has virtually completed its move away from the production and use of coal - an astonishing transformation for an economy that once relied overwhelmingly on coal power. This is however a transformation that was never really 'planned' and the move away from coal started long before concerns about climate change achieved political prominence. Until as late as November 2015, for example, there was no government commitment to phase out coal in UK electricity generation. But it was already happening, and some of the most rapid change was actually in 2016, triggered in particular by the impact of a 'carbon tax' which has tipped the economics away from coal to gas-fired generation. A handful of coal-fired power stations will remain on the grid for a few years to help meet peak demand, but to all intents the UK is already entering the post-coal era. Whether this has been achieved without undue pain to coal mining areas is however deeply questionable. Job losses were for many years managed by a combination of redundancies and transfers to surviving mines. Redundancy payments, welfare benefits and early access to pensions provided support former miners, and careers advice and training was on offer. Most former miners have now reached retirement age. The big problem for mining communities has been replacement of the lost jobs. The UK has a long history of efforts to regenerate areas affected by coal closures and there is clear evidence that this has delivered positive results in the form of new jobs. Nevertheless, there continues to

    This paper explores the effects of financial development, economic growth, coal consumption and trade openness on environmental performance using time series data over the period 1965–2008 in case of South Africa. The ARDL bounds testing approach to cointegration has been used to test the long run relationship among the variables while short run dynamics have been investigated by applying error correction method (ECM). The unit root properties of the variables are examined by applying Saikkonen and Lütkepohl (2002. Econometric Theory 18, 313–348) structural break unit root test. Our findings confirmed long run relationship among the variables. Results showed that a rise in economic growth increases energy emissions, while financial development reduces it. Coal consumption has significant contribution to deteriorate environment in South African economy. Trade openness improves environmental quality by reducing the growth of energy pollutants. Our empirical results also verified the existence of environmental Kuznets curve. This paper opens up new insights for South African economy to sustain economic growth by controlling environment from degrdation through efficient use of energy. - Highlights: • We found that a rise in economic growth increases energy emissions. • We found that financial development lowers energy emissions. • We found that coal consumption significantly deteriorate environment. • We found that trade openness improves environmental quality. • Existence of EKC is also found

    1992-01-01

    This paper reports that surging oil trade in the Asia-Pacific region is spawning a number of big petroleum storage projects there. Among the biggest are those in Indonesia and Singapore. A group led by Singapore's Sembawang Group plans to build a $272 million (Singapore) oil storage terminal on Karimun Island in Riau province, Indonesia. Other participants include Kuo International, Hong Kong, and likely companies from Japan, Europe, and the U.S. According to press reports from Jakarta and Singapore, Van Ommeren Terminals of Netherlands was also reportedly involved in negotiations on the projects. A joint venture agreement was expected to be signed by the third quarter. Plans call for building a terminal with a capacity of 1.5 million cu m on the island, where Sembawang has a 100 year lease. Ultimately, Sembawang and Indonesian company Bangun Cipta want to develop the site as an industrial city with petrochemical plants, engineering and manufacturing industries, and shipyards. Semabawang Project Engineering recently completed a feasibility study of the Karimun storage project

  8. Company-level profile of international coal trade: 1985-1990

    1992-01-01

    This article profiles the 61 parent companies from 21 countries which, in 1990, were responsible for 88% of world coal exports. The profile categorizes the parent companies according to their principal business activity, establishes the extent to which their operations are transnational, identifies those with the fastest growing coal exports and investigates the relationship between exporting and profitability. Its main findings are that the majority of coal exports are produced by companies for which coal is not their main business activity, that half of the companies in the study are transnationals but only a quarter are transnational in coal and that, in the context of declining profit margins between 1985 and 1990, there is no evidence of a relationship between the profitability of a company's coal operations and its propensity to export

    UK ports and rail operators have invested heavily to improve available capacity, but now imports are leveling off. In January to May 2007, UK coal imports totalled 19.2 mt, a drop of 6% compared to the same period in 2006. Indigenous production dropped more drastically, 23.8% to 6.62 mt. UK coal demand will be determined by such factors as the Large Combustion Plant Directive. There appears to be a second wave in the 'dash for gas' generation game as gas prices have fallen. Investment at Immingham's terminal has enabled the UK to cope with increased coal imports. ABP is now considering another coal terminal outside the locks at Hull. These plans are outlined in the article. Coal handling at Newcastle is also reported. 3 figs., 1 photos.

    Full Text Available Active growth of trade volume between India and Africa which has increased in twenty times since the beginning of the twenty-first century or in seventy times since 1991, certainly actualized a question of features of the modern Indo-African relations. In this regard the purpose of article is consideration of features of policy of India to the African countries. The author does the short historical review of the Indo-African relations, and considers key spheres of realization of modern regional strategy of India on the African continent - humanitarian projects, foreign trade and investments. The main methods of research are the comparative-historical approach and the statistical analysis, being used for identification of positive or negative dynamics of development of the Indo-African cooperation. Now the African region takes strategic significance for India. Rapid economic development of the African countries and increase in a standard of living of the population turn the continent into a perspective sales market of the Indian goods and services. Besides, India actively develops humanitarian projects and renders the financial help to many African countries. However, India faces set of problems and factors - geographical remoteness, the discrimination and racism, instability of political systems of many African countries and the African policy of China. The active economic policy of China on the African continent has compelled India to develop cooperation with the countries of Africa more actively. In recent years India also as well as China tries to make active and modernize the economic and humanitarian policy in Africa. Struggle for commodity markets of the goods and services in Africa makes Africa by strategic region not only in the Indo-Chinese relations, but in foreign policy of India as a whole.

    The paper described a summary of the 1995 study on coal liquefaction and gasification under the New Sunshine Project. As for coal liquefaction, a study was made of liquefaction characteristics and catalysts of various coals. Also studied were liquefaction conditions for quality improvement of liquefaction products, an evaluation method of quality of coal liquid, and a utilization method of coal liquid. In order to prevent carbonization and realize effective liquefaction, a study was conducted for elucidation of the reaction mechanism of high pressure hydrogenation. In a 150t/d pilot plant using hydrogen transfer hydrogenation solvents, the NEDOL method was studied using various catalysts and kinds of coals. This is a step prior to data acquisition for engineering, actual construction of equipment and operation. A 1t/d process supporting unit is a unit to support it. The unit conducts studies on slurry letdown valves and synthetic iron sulfide catalysts, screening of Chinese coals, etc. As to coal gasification, the paper added to the basic research the combined cycle power generation using entrained flow coal gasification for improvement of thermal efficiency and environmental acceptability and the HYCOL method for hydrogen production. 68 refs., 40 figs.

    Among the EDS, H-Coal and SRC-2 lined up in the coal liquefaction project of the U.S., the SRC is aimed at producing 6,000 t/day as a module for a 30,000 t/day commercial plant. They expect Ash contents (iron, sulfur, etc.) in coal without basically using catalysts. The products are applicable to fuels for electricity and gas for the moment. In the element technology, there are some problems in manufacturing hydrogen by gasification of residuals as well as in slurry systems, reaction towers, etc.. In the 30,000 ton commercial plant, the coal-liquefied oil costs $19.89/bbl (price as of 1978) assuming coal costs $29.47; therefore, the feasibility is strong as a substitute for petroleum. Japan's share for the required funds will be 86.8 billion yen (if 250 yen per dollar). Since the kinds of coal are conceivably increased in number through the improvement of the process, the Pacific rim countries and these which lie on the Indian Ocean are assumed to be the major coal producing countries for Japan. The stability in storage of coal-liquefied oil is experimentally excellent, as is the compatibility with petroleum products for example. Great results can be expected in the technical know-how and the spread of element technology for Japan. (NEDO)

    The article presents an overview of global demand and trade in hard coal (steam and coking). Coal demand has grown steadily over the past thirty years but coal trade has and will continue to grow at a faster rate. Transport contributes a relatively high proportion to the final price. Demand growth is strongest in countries with limited resources while production is declining in some countries with mature mining industries. There is a shift to demand in Asian markets. Spot contracts and tender transactions are replacing long-term contracts and e-commerce is developing. Prices are expected to remain stable, relative to those of oil and gas. China is expected to remain the world's second longest supplier of coal. 9 refs., 13 figs.

    The exploration project in Indonesia covered geological mapping, drilling, geophysical logging, underground water pumping tests, vertical seismic profiling (VSP), and seismic reflection survey. Ten boreholes were drilled. Moreover, coal property analysis, geotechnical rock test, geochemical analysis, and the like were conducted by examining core specimens sampled from the boreholes. It was found that there are three main coal beds which continuously extend to the two ends of the synclinic structure. It was also found that there is a 6m-thick coal bed 200m further below the three main coal beds, and it is estimated to produce approximately 6,000kcal/kg. Coal from two of the three beds produces 5,000kcal/kg, containing but a little ash and sulfur. Coal from the third includes 1.17% of sulfur. Coal in all the beds is summed up, and then it is estimated that there is approximately 1,054-million tons of coal in reserve in the South Arahan area. (NEDO)

    This is one of the 6 country case-studies commissioned to collect experience on past coal transitions. The 6 countries are: Czech Republic, the Netherlands, Poland, Spain, UK, USA. Their role in the Coal Transitions project was to provide background information for a Synthesis Report for decision makers, and provide general lessons for national project teams to take into account in developing their coal transitions pathways for the future. Spain has had a long tradition of coal mining at least since the 18. century. However, it is also one of the jurisdictions committing to phase-out of subsidies and implementing it in recent times. This case study discusses the main features of the coal transition in Spain, the factors influencing this transition as well as the policies which both drove it and accompanied their detrimental socioeconomic effects on the workers and regions. The analysis is based on a desktop research of relevant documents, including official communications from the Ministry of Industry (MINETUR) and the European Commission as well as statements of position from the industry association (CARBUNION) and labour unions (UGT and CCOO). Documents on national coal from other institutions (Foundations, NGOs) have also been consulted. Finally, an analysis of articles in the mass media has been carried out. This contains useful statements from different types of stakeholders. A strong reduction in production and employment in the coal industry has been experienced at least in the last two decades in this country. Successive plans by the government have aimed at reducing coal production, early retirement of workers and closing mines. Caught in the middle of the mining coalition on the one hand and EU legislation and public opinion on the other, the government has had to approve drastic measures leading to phase out. On the other hand, it has tried to accompany the phase out with measures which have tried to mitigate the negative impact on the affected zones

    While coal appears as an inescapable resource to answer the energy needs of the 21. century, its highly CO 2 emitting combustion represents a major risk with respect to the requirements of the fight against climate change. In the first part of this book, the basic aspects of energy markets are explained and in particular the role that coal is going to play in the world's energy supplies. In the second part, the new coal usages are presented, which, combined with CO 2 capture and sequestration techniques, should allow to conciliate a massive use of coal and the respect of environmental constraints. This book is based on the works presented in February 2008 by the French institute of petroleum (IFP) about the new outlets of coal and the risks for climate change. Content: 1 - coal, energy of the 21. century: abundant and well distributed reserves; growing up world production; exponential world demand; international trade: still limited but in full expansion; 2 - Technologies for a CO 2 -free coal: CO 2 capture and sequestration technologies; towards poly-generation; production of coal-derived liquid fuels; 3 - Appendices: coals formation; coal in China: status and perspectives; coal in the USA: status and perspectives; coal in India: status and perspectives; COACH: an ambitious European project; CBM - E-CBM, status and perspectives.

    Development of coal-water-fuel (CWF) technology has to-date been predicated on the use of high-rank bituminous coal only, and until now the high inherent moisture content of low-rank coal has precluded its use for CWF production. The unique feature of the Alaskan project is the integration of hot-water-drying (HWD) into CWF technology as a beneficiation process. Hot-water-drying is an EERC developed technology unavailable to the competition that allows the range of CWF feedstock to be extended to low-rank coals. The primary objective of the Alaskan Project, is to promote interest in the CWF marketplace by demonstrating the commercial viability of low-rank coal-water-fuel (LRCWF). While commercialization plans cannot be finalized until the implementation and results of the Alaskan LRCWF Project are known and evaluated, this report has been prepared to specifically address issues concerning business objectives for the project, and outline a market development plan for meeting those objectives.

    The US Department of Energy (DOE) has prepared this EA to assess the environmental impacts of the commercial application of lignite fuel enhancement. The proposed demonstration project would be implemented at Great River Energy's Coal Creek Station near Underwood, North Dakota. The proposed project would demonstrate a technology to increase the heating value of lignite and other high-moisture coals by reducing the moisture in the fuels. Waste heat that would normally be sent to the cooling towers would be used to drive off a percentage of the moisture contained within the lignite. Application of this technology would be expected to boost power-generating efficiencies, provide economic cost savings for lignite and sub-bituminous power plants, and reduce air emissions. The proposed project would be constructed on a previously disturbed site within the Coal Creek Station and no negative impacts would occur in any environmental resource area.

    1982-01-01

    Under the with-project scenario, WyCoalGas is projected to make a difference in the long-range future of Converse County. Because of the size of the proposed construction and operations work forces, the projected changes in employment, income, labor force, and population will alter Converse County's economic role in the region. Specifically, as growth occurs, Converse County will begin to satisfy a larger portion of its own higher-ordered demands, those that are currently being satisfied by the economy of Casper. Business-serving and household-serving activities, currently absent, will find the larger income and population base forecast to occur with the WyCoalGas project desirable. Converse County's economy will begin to mature, moving away from strict dependence on extractive industries to a more sophisticated structure that could eventually appeal to national, and certainly, regional markets. The technical demand of the WyCoalGas plant will mean a significant influx of varying occupations and skills. The creation of basic manufacturing, advanced trade and service sectors, and concomitant finance and transportation firms will make Converse County more economically autonomous. The county will also begin to serve market center functions for the smaller counties of eastern Wyoming that currently rely on Casper, Cheyenne or other distant market centers. The projected conditions expected to exist in the absence of the WyCoalGas project, the socioeconomic conditions that would accompany the project, and the differences between the two scenarios are considered. The analysis is keyed to the linkages between Converse County and Natrona County.

    This article described the proposed Dodds-Roundhill Coal Gasification Project. This first commercial coal gasification plant in Canada will be developed by Edmonton-based Sherritt International Corporation, in a 50/50 partnership with the Ontario Teachers' Pension Plan. The project will include a surface coal mine and a coal gasification facility located approximately 80 km southeast of Edmonton, Alberta. Coal gasification is emerging as a clean alternative for converting coal into energy products. It involves the gasification process which breaks down coal to produce hydrogen, carbon monoxide and carbon dioxide, collectively known as synthesis gas (syngas). The syngas can then be used for fuel, as a petrochemical feedstock, or it can be further processed into hydrogen for use by bitumen upgraders and crude oil refineries in Alberta. Carbon dioxide, which is highly concentrated are relatively easy to capture will be either sequestered or used in enhanced oil recovery. Construction will begin in mid-2009 following project application and an environmental impact assessment. 3 figs.

    The uncertainty about the planned CO 2 trade of the European Union (EU) is very great. For the possible buyers in this politically created market the risks may be great and difficult to assess. The most effective way of forcing a reduction of emissions is trading emission licences. But this requires taking a stand on issues of very unpleasant nature. And the Kyoto protocol evades these questions, it is a thin document right from the beginning. Trade in emission licences is one of the three so-called flexible mechanisms of the Kyoto agreement. The second mechanism is joint implementation in which one industrialized country carries out emission reduction actions in another industrialized country. The third is the mechanism of clean development, in which one industrialized country takes remedial actions in a developing country. It is unclear how these mechanisms are to act in accordance with each other, both in the Kyoto Protocol and on the level of the EU. The biggest and most fundamental uncertainty, both on the EU and global levels, relates to the fact that the partners have not decided how to define the right of ownership of emissions of a certain size

    During this period effort was devoted to: formulation of system performance goals in the areas of production cost, miner safety, miner health, environmental impact, and coal conservation, survey and in depth assessment of promising technology, and characterization of potential resource targets. Primary system performance goals are to achieve a return on incremental investment of 150% of the value required for a low risk capital improvement project and to reduce deaths and disability injuries per million man-hour by 50%. Although these performance goals were developed to be immediately applicable to the Central Appalachian coal resources, they were also designed to be readily adaptable to other coals by appending a geological description of the new resource. The work done on technology assessment was concerned with the performance of the slurry haulage system.

  14. Environmental considerations of coal gasification technology and the Wabash River Repowering Project

    Lessig, W.S.; Frederick, J.D.

    1993-01-01

    The Clean Air Act Amendments of 1990 have mandated a significant reduction in sulfur dioxide emissions. Coal gasification can assist coal burning utilities in meeting this challenge. The use of combustion turbines in the cycle is an important factor in terms of efficiency and pollution control technologies. The gasification process can be utilized in several applications including 'repowering' existing coal-fired facilities as well as new 'greenfield' projects. This paper addresses the environmental benefits of the repowering application at PSI Energy's Wabash River Station. The environmental impacts of air, water, solid waste, trace hazardous air pollutants, and fuel sources are addressed. Specifically, sulfur removal is discussed on both a technical and an economic level

    This report presents the results of (researches on solvolysis liquefaction mechanisms and reaction promotion with oil- and coal-based solvents), conducted as part of the research and development project for coal liquefaction techniques. The FY 1981 program includes researches on (1) the effects of liquefaction reaction conditions on liquefaction yield and production of light products for coal species of low degree of carbonization, including brown coal, (2) the effects of pretreatment of coal on its liquefaction reactivity, and (3) up-grading of the solvolysis coal liquid (SCL). For the item (1), HA240 (hydrogenated Ashland's A240) is used to investigate its liquefaction capacity for various coal species of low degree of carbonization, including brown coal. For the item (2), the effects of pretreatment in a hot water bath with reflux was investigated for sub-bituminous coal in the FY 1980. In the FY 1981, various pretreatment methods are attempted for enhancing liquefaction reactivity of brown coal. As a result, it is found that ash content of brown coal is decreased to one-third of the initial level, when it is treated in a diluted hydrochloric acid bath with reflux. For the item (3), SCL hydrogenated by Birch reduction (B-SCL, 1) is compared with H-SCL with respect to properties, structures and thermal crackability, to discuss the items required for the catalyst to be used in the second stage by clarifying effectiveness of the catalyst.

    2004-01-01

    Although there are a number of possible links between emission trading and project-based mechanisms, the focus of this paper is on linking domestic GHG emission trading schemes with: (1) domestic; and, (2) international (JI and CDM) GHG reduction project activities. The objective is to examine some of the challenges in linking DETs and project-based mechanisms, as well as some possible solutions to address these challenges. The link between JI / CDM and intergovernmental international emissions trading (i.e. Article 17 of the Kyoto Protocol) is defined by the Kyoto Protocol, and therefore is not covered in this paper. The paper is written in the context of: (a) countries adhering to the Kyoto Protocol and elaborating their strategies to meet their GHG emission commitments, including through the use of the emissions trading and project-based mechanisms. For example, the European Union (EU) will be commencing a GHG Emissions Trading Scheme in January 2005, and recently, the Council of ministers and the European Parliament agreed on a text for an EU Linking Directive allowing the use of JI and CDM emission units in the EU Emission Trading Scheme (EU-ETS); and (b) all countries (and/or regions within countries) with GHG emission obligations that may choose to use domestic emissions trading and project-based mechanisms to meet their GHG commitments. The paper includes the following elements: (1) an overview of the different flexibility mechanisms (i.e. GHG emissions trading and PBMs), including a brief description and comparisons between the mechanisms (Section 3); (2) an exploration of the issues that emerge when project-based mechanisms link with domestic emissions trading schemes, as well as possible solutions to address some of the challenges raised (Section 4); (3) a case study examining the EU-ETS and the EU Linking Directive on project-based mechanisms, in particular on how the EU is addressing in a practical context relevant linking issues (Section 5); (4) a

    Executive Summary-Introduction: The concepts of a global environment and economy are strongly and irrevocably linked to global energy issues. Worldwide coal production and international coal trade are projected to increase during the next several decades in an international energy mix that is still strongly dependent on fossil fuels. Therefore, worldwide coal use will play an increasingly visible role in global environmental, economic, and energy forums. Policy makers require information on coal, including coal quality data, to make informed decisions regarding domestic coal resource allocation, import needs and export opportunities, foreign policy objectives, technology transfer policies, foreign investment prospects, environmental and health assessments, and byproduct use and disposal issues. The development of a worldwide, reliable, coal quality database would help ensure the most economically and environmentally efficient global use of coal. The U.S. Geological Survey (USGS), in cooperation with many agencies and scientists from the world's coal producing countries, originally undertook a project to obtain representative samples of coal from most of the world's producing coal provinces during a limited period of time (roughly 1998-2005), which is called the World Coal Quality Inventory (WoCQI). The multitude of producing coal mines, coal occurrences, or limited accessibility to sites in some countries can preclude collecting more than a single sample from a mine. In some areas, a single sample may represent an entire coal mining region or basin. Despite these limitations in sampling and uneven distribution of sample collection, the analytical results can still provide a general overview of world coal quality. The USGS intends to present the WoCQI data in reports and, when possible, in Geographic Information System (GIS) products that cover important coal bearing and producing regions.

    The federal and most provincial governments are encouraging coal as an energy source. Coal production will increase 4-5 times by 2000 and world trade double with further increases to 2025. The Canadian steel industry is producing near capacity and forecasts a growth rate of 4% over the next ten years. Problems facing Canadian steel industry include the E1k River project, St. Lawrence toll increases, environmental coal requirements, and Chinese crude steel. Coal industry should have an excellent future if the Canadian governments can fill their leadership roles.

    One of the great challenges for policy makers in the twenty first century is turning out to be global climate change caused by greenhouse gas emissions. Recent setbacks in international negotiations do not preclude the imposition of national emission targets. One option being studied to increase the economic efficiency of meeting these targets is the creation of emissions trading markets. The exploration of credit trading in the field of greenhouse gas emissions is carried out under the banner of the Greenhouse Gas Emission Reduction Trading (GERT) Pilot Project. One of its objectives is the development of the institutional framework required for the Clean Development Mechanism (CDM), Joint Implementation (JI), and other international credit trading programs. To ensure credits are awarded to projects in a fair and transparent manner, technical, methodological, and administrative processes must be put in place. The determination of project baselines and project boundaries represent two of the main challenges confronting policy makers in awarding the credits. A review of baseline and boundary methods was initiated by GERT, and this report also contains a description of the main advantages and drawbacks of the various methods being considered. Lessons learned and opportunities are especially important for GERT to provide proper guidance to developers. The context and rationale for baselines and boundary setting are first explored in this report, as well as the issues of importance, and common criteria for the evaluation of alternative methods. The principal options for baseline determination, advantages and disadvantages, and applicability in various contexts were reviewed in section 2. The topic of avoided electricity use, and how to set consistent baselines for it are discussed in section 3. Project boundary is the topic of section 4, including leakage, upstream and downstream emissions, rebound and positive spillover effects, and means by which these issues can de

    This paper reports the investigation on coal types for coal gasification in the Sunshine Project. With regard to the status of existence, production and dressing of coals as the material for coal gasification and liquefaction, summarized site investigations and sampling were performed on underground mining coal mines being operated in Japan. Test sample coals are put into a data file as the important fundamental data for gasification and liquefaction characteristics tests at the Japan Coal Energy Center. The sampling investigation is planned to start in fiscal 1988. The coal mines having been investigated to date include: Taiheiyo Coal Mine (Kushiro), Mitsui Coal Mining Industry (Miike), Matsushima Coal Mine (Ikejima), Mitsubishi Coal Mining Industry (Minami O-Yubari), Sumitomo Coal Akabira Coal Mine (Akabira), Mitsui Coal Mining Industry (Ashibetsu), and Sorachi Coal Mine (Sorachi). Coal beds subjected to the sampling were selected upon carefully discussing with the site engineers on the current status of the coal mine, and the coal beds that could be operated in the future. The sampling method was such that the whole coal bed from the upper bed to the lower bed at the facing was sampled and put into vinyl sampling bags each at about 2 kg as the target. (NEDO)

    In consideration of the coal situation in the Asia/Pacific region, a study was made of effects of the expansion of coal trade by IPP on supply/demand of general coal in Asia. When aggregating increases in demand of general coal for electric power use in ten Asian counties, they will be an increase of 130.75 million tons in 2005 over 1997. Fifty nine percent of it is equivalent to the increase by IPP and exceeds the demand expanded by electric utilities operators. Further, a possibility is predicted of contracts and coal quality being different from until now. However, there will be a lot of cases in which plans of constructing power plants in Asia are not so developed as expected except Japan, Korea and Taiwan, and also the effect of the currency crisis starting in Thailand largely affects. In terms of the coal supply, countries which export general coal are only China and Indonesia. Indonesian coal is expanding its production and export rapidly and remarkably. The environmental control in Asia has been tightening, and the fuel selected by IPP is mainly coal rather than natural gas. 40 refs., 94 figs., 179 tabs.

    The Clean Coal Technology Demonstration Program (CCT Program), a model of government and industry cooperation, responds to the Department of Energy's (DOE) mission to foster a secure and reliable energy system that is environmentally and economically sustainable. The CCT Program represents an investment of over $5.2 billion in advanced coal-based technology, with industry and state governments providing an unprecedented 66 percent of the funding. With 26 of the 38 active projects having completed operations, the CCT Program has yielded clean coal technologies (CCTs) that are capable of meeting existing and emerging environmental regulations and competing in a deregulated electric power marketplace. The CCT Program is providing a portfolio of technologies that will assure that U.S. recoverable coal reserves of 274 billion tons can continue to supply the nation's energy needs economically and in an environmentally sound manner. As the nation embarks on a new millennium, many of the clean coal technologies have realized commercial application. Industry stands ready to respond to the energy and environmental demands of the 21st century, both domestically and internationally, For existing power plants, there are cost-effective environmental control devices to control sulfur dioxide (S02), nitrogen oxides (NO,), and particulate matter (PM). Also ready is a new generation of technologies that can produce electricity and other commodities, such as steam and synthetic gas, and provide efficiencies and environmental performance responsive to global climate change concerns. The CCT Program took a pollution prevention approach as well, demonstrating technologies that remove pollutants or their precursors from coal-based fuels before combustion. Finally, new technologies were introduced into the major coal-based industries, such as steel production, to enhance environmental performance.

    Following the earthquake of 2001 in the Kutch district of Gujarat (India), the state government and corporate investors have focussed on the coastal areas of Kutch, India's largest district, for economic and infrastructure development. Within a decade of industrialisation of this landscape, these projects have had profound impacts on the environment, livelihoods and futures of its Kutchi inhabitants. Today, the coastline between the old Kandla and Mundra ports is drawn into a three-way battle between International Financial Institutions (IFIs) investing in coal projects, technical experts of sustainable development and international anti-coal campaigners. These three groups have selectively engaged the project affected Kutchis on the importance of economic development, environmental management and climate change. But the affected local people comprising artisanal fisherfolk who belong to a minority community, economically powerful salt and agricultural farmers and a traditional pastoral community of camel herders, frame, debate and act upon the impacts of the project in pragmatic ways. The range of remedies sought by them can be located between the practical expediency of everyday life and ethical questions about correct action. These remedies offer a glimpse of what regulatory bodies should be paying attention to rather than abstract or procedural justice. - Highlights: • The Bhuj earthquake of 2001 lead to the economic reshaping of Kutch. • Coal based imports, transportation and power generation has undermined local livelihood and ecology. • Without remedies, affected people are drawn into corporate patronage relations. • Impacts need to be addressed soon, close to the site, and with local involvement. • If embedded in the locality, energy regulation can become mutually beneficial.

    The purpose of this report is to document and summarize activities associated with Fluor's efforts on the Tri-State Synfuels Project. The proposed facility was to be coal-to-transport fuels facility located in Henderson, Kentucky. Tri-State Synfuels Company was participating in the project as a partner of the US Department of Energy per terms of a Cooperative Agreement resulting from DOE's synfuel's program solicitation. Fluor's initial work plan called for preliminary engineering and procurement services to the point of commitment for construction for a Sasol Fischer-Tropsch plant. Work proceeded as planned until October 1981 when results of alternative coal-to-methanol studies revealed the economic disadvantage of the Synthol design for US markets. A number of alternative process studies followed to determine the best process configuration. In January 1982 Tri-State officially announced a change from Synthol to a Methanol to Gasoline (MTG) design basis. Further evaluation and cost estimates for the MTG facility eventually led to the conclusion that, given the depressed economic outlook for alternative fuels development, the project should be terminated. Official announcement of cancellation was made on April 13, 1982. At the time of project cancellation, Fluor had completed significant portions of the preliminary engineering effort. Included in this report are descriptions and summaries of Fluor's work during this project. In addition location of key project data and materials is identified and status reports for each operation are presented.

    Emissions trading has been an integral part of Ontario's air quality strategy since December 31, 2001. Ontario has adopted the 'cap, credit and trade' type of emissions trading system, a hybrid that takes the best features of pure 'cap-and-trade' and 'baseline-and-credit' type systems. It covers nitric oxide and sulphur dioxide. The Ontario Emissions Trading Code supplements Ontario Regulation 397/01 and sets out rules for renewable energy projects and conservation projects for which applications for emission allowances can be made. This Code describes the rules for the creation and transfer of emission reduction credits (ERCs). It also explains the rules for the operation of the registry that has been established to provide information to the public about the emissions trading program and records decisions about credit creation and credit and allowance retirement. 3 tabs

    This paper describes the achievements in the Sunshine Project in fiscal 1993 in the investigation for coal type selection. The investigation is purposed to elucidate the status of existence and resources of coals as the raw material for coal gasification and liquefaction, the coal quality features, and the gasification and liquefaction characteristics. The results will be used as the fundamental materials for technological development. Discussions will also be given on the coal applicability to the composite gasification power generation system in which liquefied residue generated in the process are mixed with the supplied coal. Coal quality analysis and a liquefaction test under the standard condition were completed on 389 test samples composed of 136 kinds of coals produced in Canada, Australia, the U.S.A., China and Indonesia. Coal types were enumerated according to the oil yield. A gasification test was performed on the specific gravity separated coals of Chinese coals to discuss the effect of change in the ash amount on the gasification characteristics. A partial coal combustion test revealed that fuel ratio, oxygen partial pressure, and oxygen molar fraction parameters affect the combustion characteristics. The micro-gravity field is effective in discussing the combustion characteristics of particulate groups of dust coal. A coal oxidizing test was performed, wherein oxidizing characteristics and spontaneous ignition performance were estimated successfully from temperature rise of heat stored in coal. The coal type matrix data were prepared. (NEDO)

  2. Strengthening national coal transitions to raise climate ambition. Issue Brief. Part of the 'Coal Transitions: Research and Dialogue on the Future of Coal' Project

    The issue of coal transitions is coming into focus in both national and international climate policy discussions. There are several drivers of this. At one level, the Paris Agreement marked a significant shift in the pace, scope and ambition of global climate change mitigation action. Consequently, it is now clear that coal will need to play a more and more diminished role in the global energy mix in the coming decades, despite carbon capture and storage (CCS) technologies. It is also increasingly clear that non-climate policy-related factors, such as rapid declines in the cost of renewable energy and battery storage, will continue to challenge the previously strong role of steam coal in the global energy mix (Randall, 2015). The business-as-usual scenario is therefore evolving quickly and the downside risks to coal demand appear to be increasing. The accumulation of these factors has in turn led to a call for an assurance of 'just transition', especially from stakeholders-notably coal sector workers and their communities-whose economic livelihoods depend on the future of an industry that will be in decline. In this context, parties to the UNFCCC will be called upon via the Facilitative Dialogue of 2018 to re-evaluate the adequacy progress and subsequently to revise their levels of ambition in their nationally determined contributions (NDCs). This moment presents an important opportunity for governments to raise the overall ambition of their policies on coal transition. But how should they do this? (author)

    For the engineer interchange project (coal mine technology field), field survey for collecting information was made on the level and trend of production technology through visits to some coal industry organizations by specialists in Russia which is one candidate for the engineer training project by sending and receiving. Although coal is positioned as an important energy resource in Russia, poor business performance and a decrease in production are reported because of privatization and cur off of subsidies during a transfer period to a market economy. In addition, severe environment surrounding the Russian coal industry such as a delay of facility renewal due to poor funds, overage facilities, and moral reduction of workers due to a rationing delay has a potential for further reduction of production. The research group thus surveyed the current state of the Russian coal industry such as actual production structures, actual coal mines, technical levels, and various problem points in Moscow and Baykal districts.

    This is a report on the training for coal technology which two Japanese engineers received in Australia. In Chapter 3 (Outline of Australia), they studied the national land, constitution of the national land, population, history, politics, economy and trade. In Chapter 4 (Coal geology), they read lecture data of university. In Chapter 5 (Outline of coal supply/demand), the coal export amount from Australia is 167 million tons. Steam coal of a little less than 50% is exported to Japan. In Chapter 6 (Coal mining technology), 100 million tons of NSW state and 100 million and 570 thousand tons of QLD state are mined by underground mining and open pit mining. Training was conducted on overburden/drilling/transportation of the open pit mining coal. As coal mining methods of underground mining, they learned the board and pillar coal mining and high wall mining as an extension of open pit mining. In Chapter 7 (Coal preparation), they observed/studied the jig, heavy media separator, heavy media cyclone separator, flotation equipment, spiral ore dressing equipment, fine powder centrifugal dewatering equipment, thickener, sieve, etc. They studied by data or by observation in Chapters 8 (Outline of coal mine), 9 (Outline of export port), 10 (Outline of railroad transportation), and 11 (Quality management).

    Carbon dioxide is considered to be the main challenge for the coal-based power generation as well as for any other industrial application of coal. Poland's energy sector is primarily based on coal combustion that covers almost 90% of demand. Future development of that sector depends on the restriction on value of carbon dioxide emission or trading allowances. There are two main technological approaches to development of new coal based generation capacity, namely: gasification and pre-combustion capture; supercritical combustion and post-combustion capture. The current situation in development of three this type projects in Poland is presented.

    The first part of this report comments the evolution of coal demand which has doubled during the last 35 years for different reasons (increase of electricity production, development of China and India), but is still based on local production although coal international trade increased indeed quicker than coal demand. It notices that there is still a lot of coal available for the future, and that demand will keep on increasing. It outlines that coal will have to reduce its impacts on the environment, and presents the technologies which will allow this reduction. It also presents the technologies for CO 2 capture and storage (CCS), and evokes its regulatory issues and its environmental impacts. Some research and development projects in CCS in different countries (Europe, Germany, United States, Australia) are presented. Finally, it stresses the importance of a global deployment of much less polluting technologies to limit greenhouse gas emissions

    The Chiyoda Thoroughbred CT-121 flue gas desulfurization (FGD) process at Georgia Power`s Plant Yates completed a two year demonstration of its capabilities in late 1994 under both high- and low-particulate loading conditions. This $43 million demonstration was co-funded by Southern Company, the Electric Power Research Institute and the DOE under the auspices of the US Department of Energy`s Round II Innovative Clean Coal Technology (ICCT) program. The focus of the Yates Project was to demonstrate several cost-saving modifications to Chiyoda`s already efficient CT-121 process. These modifications included: the extensive use of fiberglass reinforced plastics (FRP) in the construction of the scrubber vessel and other associated vessels, the elimination of flue gas reheat through the use of an FRP wet chimney, and reliable operation without a spare absorber module. This paper focuses on the testing results from the last trimester of the second phase of testing (high-ash loading). Specifically, operation under elevated ash loading conditions, the effects of low- and high-sulfur coal, air toxics verification testing results and unexpected improvements in byproduct gypsum quality are discussed.

    China's economic growth is expected to continue into the next decades, accompanied by a sustained urbanization and industrialization. The associated increase in demand for land, water resources and rich foods will deepen the challenge to sustainably feed the population and balance environmental and agricultural policies. In previous work, Inner Mongolia was identified as a target province for trade or agricultural policies aimed at water-use efficiency improvements, due to its large production relying on particularly significant irrigation water use. In addition, water scarcity issues may arises in the greater Beijing area, which represents the largest urban area of arid Northern China. Increasing residential and industrial water demand in this region may lead to fewer available water for irrigation. For these reasons, it is important to estimate the impacts of specific policies aiming at reducing excessive water use for crop production in Inner Mongolia, as well as exploring ways to mitigate pressure on water resources in dry urban areas. In this study, we use socio-economic projections to assess the future state of China's virtual water trade (VWT) network. We then quantify the effects of agricultural policies on the national VWT system and on the efficiency of food trade in terms of water resources. This study addresses the following questions: (1) How future socio-economic changes will affect China's food trade and associated water transfers? (2) To which extent localized reductions of irrigated area can decrease agricultural water use while maintaining national food security? (3) How would these policies affect China's domestic and international VWT network and induced water resources savings (losses)?

  9. Outlook and challenges to coal in Asia: 1994--2015

    International Nuclear Information System (INIS)

    1996-02-01

    The two key threats to coal's long term dominance in Asia are: (1) its uneven distribution of reserves and lack of adequate rail transportation infrastructure, and (2) growing environmental concerns about coal-related pollution. Even with increased attention to emissions control for coal, continued growth in coal consumption is expected to result in further deterioration of the environment in Asia for another one to two decades. China will remain the largest polluter in Asia, but it's believed it will become Asia's largest user of emissions control technology by 2015. The authors have subjectively weighed the above constraints to increased coal use in preparing the projections of the future role of coal in the Asian region. This paper shows past trends in coal production and consumption, plus projections of coal production, consumption and trade over the 1994--2015 period. The projections in this paper are useful as a general indicator of long term patterns in Asia. However, there are too many uncertainties about economic growth rates and energy and environmental policies to suggest that the projections will be accurate for every economy. This paper concludes with the preliminary results of research under way, which suggests that increasing economic wealth in China is the most important factor in solving China's coal-related pollution problems

    The purpose of the present study is to elucidate coal quality features of different types of coals and identify the relationship between the coal quality features and the liquefaction characteristics by performing liquefaction characteristic evaluation tests. Based on the result therefrom, a method is established for coal field assessment that can estimate yield of liquefaction in coal fields and coal mines to serve for selection of coal types suitable for liquefaction. Coal quality feature surveys and liquefaction characteristics evaluation tests under the standard conditions have been completed on 48 coal types including Canadian, Australian and American coals. Elucidating the coal quality features of different coals can specify parameters for the coal quality features related to the liquefaction characteristics. Coal ranks elucidate the vitrinite reflectance, structure constituent factors the vitrinite content, composite factors the volatile matter content, quantity of heat generation, and number of H/C and O/C atoms. Investigating the relationship between the coal quality features and the liquefaction characteristics can provide fundamental data for primary screening of raw material coals for liquefaction. The result of the liquefaction characteristics evaluation test under the standard conditions can be the detailed comparative data relative to data derived from the simplified liquefaction characteristics test that is performed to estimate liquefaction yield of specific coal field and coal mine.

    Participation by US firms in the development of Clean Coal. Technology (CCT) projects in foreign countries will help the United States achieve multiple national objectives simultaneously--addressing critical goals related to energy, environmental technology, industrial competitiveness and international trade. US participation in these projects will result in an improved global environment, an improvement in the balance of payments and an increase in US jobs. Meanwhile, host countries will benefit from the development of economically- and environmentally-sound power facilities. The Clean Air Act Amendments of 1990 (Public Law 101-549, Section 409) as supplemented by a requirement in the Energy Policy Act of 1992 (Public Law 102-486, Section 1331(f)) requires that the Secretary of Energy, acting through the Trade Promotion Coordinating Committee Subgroup on Clean Coal Technologies, submit a report to Congress with information on the status of recommendations made in the US Department of Energy, Clean Coal Technology Export Programs, Report to the United States Congress, February 1992. Specific emphasis is placed on the adequacy of financial assistance for export of CCTS. This report fulfills the requirements of the Act. In addition, although this report focuses on CCT power projects, the issues it raises about the financing of these projects are also relevant to other CCT projects such as industrial applications or coal preparation, as well as to a much broader range of energy and environmental technology projects worldwide.

  13. A Multi-Objective Trade-Off Model in Sustainable Construction Projects

    2017-10-01

    Full Text Available Based on the consideration of the relative importance of sustainability-related objectives and the inherent nature of sustainable construction projects, this study proposes that the contractor can balance the levels of efforts and resources used to improve the overall project sustainability. A multi-objective trade-off model using game theory was established and verified through simulation and numerical example under a moral hazard situation. Results indicate that effort levels of the contractor on sustainability-related objectives are positively related to the outcome coefficient while negatively to the coefficients of effort cost of the relevant objectives. High levels of the relative importance of sustainability-related objectives contribute to high levels of effort of the contractor. With the variation in effort levels and the coefficient of benefit allocation, the project net benefit increases before declining. The function of project benefit has a marked peak value, with an inverted “U” shape. An equilibrium always exists as for the given relative importance and coefficients of the effort costs of sustainability-related objectives. Under this condition, the owner may offer the contractor a less intense incentive and motivate the contractor reasonably arranging input resources. The coefficient of benefit allocation is affected by the contractor characteristic factors and the project characteristic factors. The owner should balance these two types of factors and select the most appropriate incentive mechanism to improve the project benefit. Meanwhile, the contractor can balance the relative importance of the objectives and arrange the appropriate levels of effort and resources to achieve a sustainability-related objective. Very few studies have emphasized the effects of the relative importance of sustainability-related objectives on the benefits of sustainable construction projects. This study therefore builds a multi-objective trade

    This paper reports that one of the main characteristics of international coal trade in the 1980's was a much higher growth rate recorded in steam coal trade than in coking coal trade. Another was that coal import in Asia started to expand rapidly at the start of the 1980's. Increased coal imports by Asian countries is primarily attributed to growing steam coal imports. Steam coal accounted for more than two-thirds of the additional coal imports by Asian countries between 1980 and 1988. Nonetheless, coking coal still forms the largest segment of Pacific coal trade. Only in the early 1990's is steam coal trade expected to exceed coking coal trade in the Pacific

    The total busbar electric generating costs were estimated for locations in ten regions of the United States for base-load nuclear and coal-fired power plants with a startup date of January 2000. For the Midwest region a complete data set that specifies each parameter used to obtain the comparative results is supplied. When based on the reference set of input variables, the comparison of power generation costs is found to favor nuclear in most regions of the country. Nuclear power is most favored in the northeast and western regions where coal must be transported over long distances; however, coal-fired generation is most competitive in the north central region where large reserves of cheaply mineable coal exist. In several regions small changes in the reference variables could cause either option to be preferred. The reference data set reflects the better of recent electric utility construction cost experience (BE) for nuclear plants. This study assumes as its reference case a stable regulatory environment and improved planning and construction practices, resulting in nuclear plants typically built at the present BE costs. Today's BE nuclear-plant capital investment cost model is then being used as a surrogate for projected costs for the next generation of light-water reactor plants. An alternative analysis based on today's median experience (ME) nuclear-plant construction cost experience is also included. In this case, coal is favored in all ten regions, implying that typical nuclear capital investment costs must improve for nuclear to be competitive

  17. Projected costs of generating electricity from nuclear and coal-fired power stations for commissioning in 1995

    1986-01-01

    This report updates and extends the previous NEA study, ''The Costs of Generating Electricity in Nuclear and Coal-fired Power Stations'', published by the OECD in late 1983. Despite the changed expectations concerning coal prices and the considerable movements in exchange rates since the first study was completed, the conclusions remain essentially the same. Nuclear Power is projected to be economically superior by a significant margin to coal-fired plants for base load electricity production in Europe, Japan and some regions of North America. In areas of North America in close proximity to supplies of cheap coal, this would be the more economic fuel, unless future nuclear investment costs can be reduced to match the best US and Canadian experience. In all regions considered, the economic advantage of both coal and nuclear over oil and gas-fired plants for commissioning in the mid-1990s is expected to be substantial. These conclusions are based on an analysis of cost projections for 900 MWe to 1400 MWe Light Water Reactors to be commissioned in 1995, operating at a levelised load factor of about 72 per cent over an assumed 25 years economic life and calculated with a 5 per cent (real) discount rate. This parallels the reference reactor selected for the NEA report ''The Economics of the Nuclear Fuel Cycle'', which was published by the OECD in June 1985, though it deviates somewhat from the reference conditions of the previous generation cost study. Contemporary coal-fired stations ranging in capacity from 330 MWe to 700 MWe with the same assumed economic life and load factor provide the basis for comparison. Some data are included on CANDU Pressurised Heavy Water Reactors, and a brief comment is annexed on the relevance of the comparisons for the smaller plants that may be of interest to countries with smaller electricity networks or where special circumstances apply

    This report was prepared in response to the guidance provided by the Congress in the course of the Fiscal Year 1995 appropriations process for the Department of Energy`s (DOE) Office of Fossil Energy (FE). As described in detail below, DOE was directed to make the international dissemination of Clean Coal Technologies (CCTs) an integral part of its policy to reduce greenhouse gas emissions in developing countries. Congress directed DOE to solicit ``Statements of Interest`` in commercial projects employing CCTs in countries projected to have significant growth in greenhouse gas emissions. Additionally, DOE was asked to submit to the Congress a report that analyzes the information contained in the Statements of Interest, and that identifies the extent to which various types of Federal incentives would accelerate the commercial availability of these technologies in an international context. In response to DOE`s solicitation of 18 November 1994, 77 Statements of Interest were received from 33 companies, as well as five additional materials. The contents of these submittals, including the requested Federal incentives, the CCTs proposed, the possible host countries, and the environmental aspects of the Statements of Interest, are described and analyzed in the chapters that follow.

    A program to demonstrate Solvent Refined Coal (SRC) technology has been initiated by the US Department of Energy (DOE) in partnership with two industrial groups. Project management responsibility has been assigned to the Oak Ridge Operations Office (ORO) of DOE. ORO requested that the Oak Ridge National Laboratory assess current research and development (R and D) activities and develop recommendations for those activities that might contribute to successful completion of the SRC demonstration plant projects. The objectives of this final report are to discuss in detail the problem areas in SRC; to discuss the current and planned R and D investigations relevant to the problems identified; and to suggest appropriate R and D activities in support of designs for the SRC demonstration plants. Four types of R and D activities are suggested: continuation of present and planned activities; coordination of activities and results, present and proposed; extension/redirection of activities not involving major equipment purchase or modifications; and new activities. Important examples of the first type of activity include continuation of fired heater, slurry rheology, and slurry mixing studies at Ft. Lewis. Among the second type of activity, coordination of data acquisition and interpretation is recommended in the areas of heat transfer, vapor/liquid equilibria, and physical properties. Principal examples of recommendations for extension/redirection include screening studies at laboratory scale on the use of carbonaceous precoat (e.g., anthracite) infiltration, and 15- to 30-day continuous tests of the Texaco gasifier at the Texaco Montebello facility (using SRC residues).

    The thesis comprises four interrelated essays featuring modelling and analysis of coal markets. Each of the four essays has a dedicated chapter in this thesis. Chapters 2 to 4 have, from a topical perspective, a backward-looking focus and deal with explaining recent market outcomes in the international coal trade. The findings of those essays may serve as guidance for assessing current coal market outcomes as well as expected market outcomes in the near to medium-term future. Chapter 5 has a forward-looking focus and builds a bridge between explaining recent market outcomes and projecting long-term market equilibria. Chapter 2, Strategic Behaviour in International Metallurgical Coal Markets, deals with market conduct of large exporters in the market of coals used in steel-making in the period 2008 to 2010. In this essay I analyse whether prices and trade-flows in the international market for metallurgical coals were subject to non-competitive conduct in the period 2008 to 2010. To do so, I develop mathematical programming models - a Stackelberg model, two varieties of a Cournot model, and a perfect competition model - for computing spatial equilibria in international resource markets. Results are analysed with various statistical measures to assess the prediction accuracy of the models. The results show that real market equilibria cannot be reproduced with a competitive model. However, real market outcomes can be accurately simulated with the non-competitive models, suggesting that market equilibria in the international metallurgical coal trade were subject to the strategic behaviour of coal exporters. Chapter 3 and chapter 4 deal with market power issues in the steam coal trade in the period 2006 to 2008. Steam coals are typically used to produce steam either for electricity generation or for heating purposes. In Chapter 3 we analyse market behaviour of key exporting countries in the steam coal trade.

    This paper describes the demonstrative project for coal preparation technology, as a part of the measures against environmental pollution due to the structuring of demonstration and dissemination basis for clean coal technologies in China, The results for fiscal 1999 is reported. In the utilization of coal in China, a problem of urgency is the highly efficient selection and removal of sulfur contents in raw coal. Coal production in Chongquing City is yearly 30 million tons, of which 90% contains sulfur contents of 3% or higher. At Jinjia Colliery of Panjiang Coal and Electric Co. Ltd., Guizhou Province, a site for the present project, a number of coal seams are unsuitable for single utilization because of high sulfur contents. The coal preparation technologies to be introduced are expected to improve coal preparation efficiency and desulfurization ratio in terms of both the washability of raw coal and the accuracy of the coal washer. This is the third year of the project, with the following activities performed, namely, research/design, manufacturing/procurement of equipment, design for construction work, training of operators or the like, and documentation. The manufacturing and procurement are for such equipment as vacuum disk filter with accessories, waste water thickener, pressure filter for tailings with accessories, flocculant pump/piping, slurry tank/pump, high-shear mixer with accessories, and electric instrumentation. All the equipment arrived at the site in January, 2001. (NEDO)

    The paper described JCOAL`s project on the exchange of technical coal engineers of China. In the project on sending of engineers to China in the first term, coal mine engineers of Japan (Taiheiyo Coal Mine, Kushiro Works, Training Center) were sent to the Daitun coal-thermal power plant, Peixuan city, Jiangsu province, in September, 1997 to introduce the production control technology in Japan. They contributed to the heightening of productivity in coal mines in China. Eighteen Chinese participated in the training. Mechanization has been comparatively well in progress, and it was 83% in coal mining and 91% in drilling. The kind of coal is mostly a raw material coal. The stuff members are 30,000, and expert engineers are 4,200. The plant has an output of 130,000 kWh, owns its railroad, is run on the general multiple management, and is largely developing. The project on sending of engineers to China in the last term was carried out in February 1998 for tracing/confirming how the results of the training conducted in September are made the most of and if or not there is something bad and for obtaining the detailed data. A certain degree of promotion and effects were able to be confirmed. A project on training of the head, sub-head, etc. who were invited to Japan to lean production/management control was also carried out in November and December 1997. 1 tab.

    With the development of clean coal technology, modern coal-fired power plants have achieved the similar emission standards as gas power plants. However, due to the impressions of high pollution and high emission in traditional coal-fired power plants, such projects are often opposed by local residents, which hinder the promotion of this technology. This manuscript aims to investigate public attitudes toward these projects and to analyze the influencing mechanisms of the factors of public support. The conceptual model was built with sense of place, trust and environmental attitude as the independent variables, benefit and cost perceptions as the mediating variables and public support as the dependent variable. The model was tested and modified by structural equation modelling. The results revealed that sense of place had a slight indirect impact (−0.043) on public support through benefit perception, whereas trust had a direct impact (0.332) on public support and indirect impacts (0.298) through benefit and cost perceptions. Environmental attitude had indirect impacts on public support through benefit perception (0.180) and cost perception (−0.115). In addition, policy suggestions on decision-making, project publicity and compensation strategy are proposed to enhance public support for similar projects. - Highlights: • This manuscript aims at eliminating the NIMBY effects on modern coal-fired power plant project. • A SEM model is proposed to explore how potential factors affect public support. • Trust is the dominant influencing factor to improve public support with both direct and indirect impacts. • Environmental attitude can also have positive effect on public support through rational compensation plans.

    Title IV of the Clean Air Act Amendments of 1990 (P.L. 101-549) uses tradeable SO 2 allowances as a means of reducing acidic emissions from the electricity generating industry. The use of emission allowances generates two important results; first, utilities are given the flexibility to choose their optimal (least cost) compliance strategies and second, the use of emission allowances creates greater incentives for the development and commercialization of innovative emissions control technology. Clean Coal Technologies (CCTs) are able to generate electricity more efficiently, use a wide variety of coal grades and types, and dramatically reduce emissions of SO 2 , NO x , CO 2 , and PM per kWh. However, development and adoption of the technology is limited by a variety of regulatory and technological risks. The use of SO 2 emission allowances may be able to provide incentives for utility (and nonutility) adoption of this innovative technology. Emission allowances permit the utility to minimize costs on a systemwide basis and provides rewards for addition emission reductions. As CCTs are a more efficient and low emitting source of electricity, the development and implementation of this technology is desirable. This paper will explore the relationship between the incentives created by the SO 2 allowance market and CCT development. Regulatory hindrances and boons for the allowance market shall also be identified to analyze how market development, state mandates, and incentive regulation will effect the ability of allowances to prompt CCT adoption

    This study attempts to estimate the current stage of the permafrost environment in the Muli coal mining area, an opencast mining site in the Qinghai-Tibet plateau, China. The estimation is done by regarding this site's permafrost environment as a system which was divided into three subsystems consisting of permafrost freeze-thaw erosion sensibility, permafrost thermal stability, and permafrost ecological fragility. The subsystems were characterized with their influencing indicators, each of which was assigned with a weight according to analytic hierarchy process. The relationship between these indictors is established using an environmental evaluation model based on grey system theory. The evaluated results show that currently the normalised grey relation projection values (GRPV) of permafrost freezing-thawing erosion sensibility, permafrost thermal stability, permafrost ecological fragility and permafrost environment are 0.58 (general situation), 0.47 (bad situation), 0.63 (general situation) and 0.56 (general situation), respectively. These values imply that the permafrost environment has been deteriorated to a certain degree by human activities and potentially could be further degraded. However, at this degree, a new equilibrium could be achieved if the current environmental degradation ratio is held and if effective treatments are constructed against further damages.

    This paper reports the achievements in the Sunshine Project in fiscal 1988 in studies on the studies of the initial process in liquefaction. It is intended to identify the swelling phenomenon in coal particles in the coal slurry preparation and preheating processes, and change in the slurry viscosity associated with the heating. The slurry viscosity starts decreasing from around 300 degrees C at which the liquefying reaction begins, and decreases sharply at around 350 degrees C. Therefore, rise in the viscosity at temperatures below 300 degrees C is caused by factors other than the liquefying reaction. The rise starting at 100 to 120 degrees C is due to absorption of the solvent by coal. The rise starting at 210 to 260 degrees C requires further discussions. The equilibrium swelling ratio was measured on different types of coals by using the hydrogenated anthracene oil solvent. No coals swelled at 100 degrees C. The temperature of 200 degrees C largely divides coals into those swelling and those not swelling. At 300 degrees C, the coals were divided into those shrinking after largely swelling, those not swelling and those swelling monotonously. For consideration of the utilization as an auxiliary solvent, petroleum-based heavy oil was used to perform coal liquefaction to discuss effects of the solvent on the liquefaction rates. (NEDO)

    For too many years, problems associated with frozen coal have plagued the companies who mine it, the companies who handle it in transit and the utilities and other industrial concerns that finally burn it. But never before has the magnitude of the frozen coal problem been as great as it is today because of two primary factors, i.e. (1) the majority of coal currently transported and used has been ground to a very fine mesh that absorbs water readily, thus providing more surface area for freezing, and (2) the substantially increased importance of coal, indeed, the now critical necessity for more coal to be used in displacing dangerously uncertain foreign oil supplies that currently account for 50 percent of our daily domestic oil consumption. Frozen coal problems can and do have a devastating effect upon the ability to provide energy from coal during harsh winter months when it is not needed. The majority of these problems have been involved with removing frozen coal from rail cars. To allay the problem, numerous techniques have been tried, all with some measure of success. As an example, certain chemicals have been sprayed on the coal; another common treatment has been widespread use of thaw sheds, which, whether electrically or gas-fired, are all energy intensive, time consuming, hard on rail equipment and expensive to operate over long periods of time. From sledge hammers and crow bars to gas-fired jets and electric thaw sheds, available mechanical de-icing methods often damage coal handling equipment, are time consuming and, therefore, very expensive when demurrage losses must be added to significant investment and/or operating costs.

    This advance survey on Russia has performed visiting surveys and information collection at coal related organizations inside Japan and in overseas countries on production technology levels, trends and technology exchange needs in overseas coal producing countries. The project is intended to serve for improvement in the contents of and smooth execution of the engineer exchange project in the 'coal mine technology field. It was carried out by expertise people as the site surveys and the engineer reception and exchange surveys. Because of the economic crisis that has hit Russia in 1998, unprofitable coal mines were closed one after another under the coal mine scrap and build policy under the initiative of the World Bank. This situation is giving serious impacts on coal mines in the Far East Russia and the coastal areas. However, the importance of coal as the primary energy source has not been changed at all in the Far East Russia. Thus, the areas have fallen into a situation that they must rely on a great amount of introduced and imported coals as a result of weakening in coal mines in the Far Eastern area on the other hand. This paper reports mainly the situation in which the coal industries in the coastal areas are placed, and the possibilities of technology exchange. (NEDO)

    This data book summarized the proceedings and the technical report of the management committee on the Japan-China geological structure survey based on the consultation concluded between NEDO and China's bureau of coal field geology and a report meeting on the Yu Xian project. In the exploration, conducted were the boring survey of 10 boreholes, seismic survey of 2D (71 traverse lines, 180.105km) and 3D (1.5km{sup 2}), VSP (6 holes (345 shots)) and the low velocity band survey (2,072 shots). The geological structure of the area presented the syncline structure with a gentle line associated with foldings and a number of faults and was classified into the medium class or the class of a little complication in the Chinese standard. The number of the faults confirmed in this exploration totaled 57. Coal reserves by coal seam were 157.22 million tons at No. 5 seam and 102.57 million tons at No. 1 seam. The total amount of the two seams was 79.1% of the total coal amount in all area. The coal quality of Nos. 1 and 5 was brown coal - flame coal in the Chinese classification, and subbituminous coal B - subbituminous coal C in the ASTM classification. The coal, however, cannot be used for process raw coal. There is a technical potentiality of the fixed bed pressurized gasification. (NEDO)

    In early 1991, British Coal reviewed its existing personnel and manpower planning systems and concluded they were inadequate for the future needs of the business. With wages accounting for 40% British Coal's 1990/91 operational costs, the Corporation targeted manpower management as an area to deliver further improvements. British Coal's strategy to continue to improve productivity required payroll and personnel related systems which could support new flexible working hours and variable shifts. This strategy would enable machine running time to be increased, leading to improved productivity levels. 3 figs.

    The proposed Sage Creek Coal Project is analysed with respect to environmental impacts, international concerns and public concerns. Although information available to date is insufficient to pursue an analysis enabling a determination of the full social and environmental cost of the project, basic concerns and issues have been elucidated. Emphasis is given to the potential adverse effects on existing fish species and on wildlife species, particularly grizzly bear, moose and mountain goat. Because the area affected by the project includes both Canadian and U.S. territory, environmental objectives of the U.S. government for the Upper Flathead Valley ecosystem must also be considered in any future B.C. government decisions. Public opposition to the project from an environmental standpoint is documented. The report concludes the preferred option for a Ministry of Environment position is to recommend the project not proceed.

  19. The European Coal Market: Will Coal Survive the EC's Energy and Climate Policies?

    International Nuclear Information System (INIS)

    Cornot-Gandolphe, Sylvie

    2012-01-01

    The European coal industry is at a crossroads. The European Commission (EC) Energy Policy by 2020, the 20/20/20 targets, is not favourable to coal: a 20% decrease in CO 2 emissions does not favour coal compared with natural gas, its main competitor in electricity generation; a 20% increase in energy efficiency will lead to a decrease in energy/coal consumption; a 20% increase in renewables will displace other energy sources, including coal. The recent EC Energy road-map to 2050 targets a cut in GHG emissions by 80-95%. Under such a tough emissions reduction target, the future use of coal is tied with CCS technologies for which public acceptance and an adequate CO 2 price are crucial. The Large Combustion Plants Directive has already had a huge impact on EU coal-fired electricity generation. In UK, a third of coal-fired power capacity will be closed by the end of 2015 at the latest. Phase III of the EU Emissions Trading Scheme requires CO 2 allowances to be auctioned from January 2013, adding a new burden on fossil fuel power plants. The end of state aid to European hard coal production by 2018, in line with EC Council Decision 2010/787/EU, means that domestic production is going to decrease. Does this mean the end of coal in Europe? Maybe not, and certainly not by 2020, although its future after that date is quite uncertain. Coal provides 17% of the EU s primary energy supply, and represents 25% of electricity generation. With the phasing out of nuclear energy in some countries (mainly Germany), coal has gained a period of grace before the transition to a less-carbonised economy. Its consumption by European power utilities increased by 7% in the first half of 2012, boosted by low CO 2 prices and relatively high gas prices. European production still accounts for 60% of the total coal supply in the EU. Coal therefore gives the EU a certain degree of independence and contributes to its security of supply. Hard coal and lignite represent approximately 80% of EU

    Out of the research and development on the 1991 Sunshine Project, the results of coal liquefaction/gasification are reported. The basic research of coal liquefaction/gasification is conducted. The research plan for a 150 ton/day scale pilot plant (PP) is worked out for the development of bituminous coal liquefaction technology by NEDOL process. Data of PSU (Process Support Units) operation, especially, are studied. Concerning the data obtained through dismantling of the 50 ton/day PP in Australia which uses Australian Victoria coal due to completion of its operation and also obtained from its support research, they are reflected in the design of a demonstration plant, and the results are arranged for study. Research and development on refining technology of coal-derived liquid such as Illinois coal liquid and on application technology of its products are made. For the development of coal-use hydrogen production technology, conducted is the research of a high temperature gasification PP by entrained flow bed process which is the core of the coal gasification technology. Elementary study with a 2 ton/day furnace is made for the development of the entrained flow bed coal gasification combined cycle power generation system. Also conducted are PP construction, adjusting operation and the overall research operation.

    We have continued our laboratory studies of forward gasification in small blocks of coal mounted in 55-gal drums. A steam/oxygen mixture is fed into a small hole drilled longitudinally through the center of the block, the coal is ignited near the inlet and burns toward the outlet, and the product gases come off at the outlet. Various diagnostic measurements are made during the course of the burn, and afterward the coal block is split open so that the cavity can be examined. Development work continues on our mathematical model for the small coal block experiments. Preparations for the large block experiments at a coal outcrop in the Tono Basin of Washington State have required steadily increasing effort with the approach of the scheduled starting time for the experiments (Fall 1981). Also in preparation is the deep gasification experiment, Tono 1, planned for another site in the Tono Basin after the large block experiments have been completed. Wrap-up work continues on our previous gasification experiments in Wyoming. Results of the postburn core-drilling program Hoe Creek 3 are presented here. Since 1976 the Soviets have been granted four US patents on various aspects of the underground coal gasification process. These patents are described here, and techniques of special interest are noted. Finally, we include ten abstracts of pertinent LLNL reports and papers completed during the quarter.

    While the introduction and adaptation of the Longwall excavation technology were carried forward for coal producing countries in the Pacific region, U.S.A. information was collected by making tours of coal mines in the West and Washington/Colorado/Utah States, with the intention of ascertaining technological trend so as to carry out efficient technological transfer, and for the purpose of replenishing the contents and contributing to the smooth implementation of the engineer exchange project in 'coal mine technological field'. The coal reserves are 400 billion tons, with 840 million tons produced and with 80 million tons exported; not less than 56% of the U.S. domestic electricity rests on coal. Production by open-pit mining is the majority while the output by underground mining is 38%; the Longwall method has increased as a digging method, taking 18% of all digging output. The productivity is 4.24 ton/person per day and ranks as the world highest. The coal mining technological trend in the U.S. can be summarized as follows. The coal mining output in the West is increasing, with the number of mines decreasing, so that the output per mine is increasing. With the output ratio by open-pit mining increasing, the digging method in the mine is being changed to the Longwall. (NEDO)

    This project has been performed with an intention of making visiting surveys and information collection at coal related organizations in overseas coal producing countries on production technology levels and trends. The project is intended to serve for improvement in the contents of and smooth execution of the engineer exchange project in the 'coal mine technology field. It was carried out by the site surveys. The surveys revealed that the situation of the American coal industry is expected of stable increase in the demand and supply in the future, but the coal price is on the falling trend, and therefore, the industry is compelled to further increase the intensity and enhance the productivity. The industry is strongly influenced by the amended air pollution prevention act and nature destruction problems, hence further coal mine curtailment is estimated. Under such a background, it was found that the long-wall mining process progressing toward larger scale and higher productivity, and the high-wall mining process that provides higher productivity at lower cost and has less impact on the environmental problems can continue development in mountainous areas, particularly in the Appalachian area. The high-wall mining process mines coal at exposed facings on the side of a mountain by using a continuous miner, and transports the coal using machines. (NEDO)

    In this report the Government has provided information on recent trends in Australia's energy trade and examined the implications of recent changes in those trends for the remainder of the 1980's. The opportunities for Australia as an energy exporter in the years ahead have been identified, along with related policy issues. The Committee has concluded that energy export projections made as recently as two years ago which foreshadowed massive increases in exports of coal, gas and uranium from Australia over the next couple of decades must now be considered excessively optimistic, given slack world economic conditions and the softer trend in world oil prices. The Committee has, however, cautioned against becoming too gloomy and of taking the immediate past period as a basis for projecting the longer term.

The survey was conducted of a locational possibility of a coal liquefaction commercial plant to be located at mine site in South Sumatra for Banko coal raw material. The improved BCL process was applied in which the results of the study by NBCL Takasago Research Institute were reflected. Further, the hydrogen production was studied by gasification of Banko coal, and the comparison was made with the conventional natural gas reforming method. As a result of the study using information/knowledge obtained during the conceptual design of Australian brown coal, the construction cost of commercial scale liquefaction plant with the Banko coal processing amount of 30,000 tons/day became 549.8 billion yen in the case of using natural gas as raw material for hydrogen production. This construction cost is the lowest as compared with 601.7 billion yen in the demonstrative BCL process and with 577.1 billion yen in the advanced BCL process. This is a process making use of features of Banko coal. The process for hydrogen production by the steam reforming method using natural gas has an advantage of increasing the production amount of coal-derived liquid the most of the three other methods.

    This survey in Europe surveyed the current status of the coal industry, supporting directions and policies of governments on the coal industry, and summarized the information thereof. The survey included movements in policies and activities in transfer of technologies to overseas countries by governments and corporations of different countries, and the current status of the coal technology training project. The survey covered Britain and Germany. The British coal industry is facing a serious difficulty because the electric power industry being the major coal purchaser has changes its sourcing to natural gas. In addition, the open-cut mining which has been considered high in productivity has no further hope of big progress due to regulations in the environmental aspects. However, as a result of having performed positively research and development on production cost reduction, the production efficiency has grown excellently. Using this situation as the base, positive advancement into overseas countries is being carried out. The German coal industry has, in spite of having reduced the production size and the number of coal mines, shifted coal purchasers to electric power generation and steel making areas, and its quality and supply capability stand equivalent to those of imported coals.

    Full Text Available Mining is unsurprisingly considered a high-risk occupation because it involves continuous hard labour under highly demanding and stressful conditions. Many of these work stressors can impair individuals’ well-being in both a physiological and psychological sense. The aims of this study were to assess the prevalence of burnout and depressive symptoms and to evaluate aspects of proactive coping among underground coal miners in Serbia. The study involved 46 male underground coal miners. Burnout was measured with the Copenhagen Burnout Inventory, depression was assessed with the Patient Health Questionnaire-9, and level of proactive coping was measured with the Proactive Coping Inventory. The results showed a low level of burnout syndrome among the underground coal miners (12.46±4.879. Depression was slightly above the minimum (1.2±2.094, and the majority of the participants had no symptoms of depression (93.5%. Overall, the underground coal miners’ ability to proactively cope with work stress was very good (42.17±6.567. This is in contrast to the findings of the few previous international studies and is a good basis for further research using a larger sample in Serbia.

    Multiple economic and geologic factors are driving fundamental changes in the nation’s energy system, weakening coal’s dominance as a fuel for electricity generation, with significant implications for places like West Virginia that are heavily dependent on coal for economic activity. Some of these factors include low natural gas prices, rising labor costs and declining productivity, economic competition with other coal mining regions, environmental regulations to reduce pollution and safeguard public health, state energy efficiency and renewable electricity standards, falling costs of renewable energy resources like wind and solar, and the likely prospect of future limits on greenhouse gas emissions. This analysis uses an input–output model to examine the effects on West Virginia’s economy from these multiple factors by exploring a range of scenarios for coal production through 2020. In addition to changes in the coal industry, hypothetical investments in additional sectors of the economy are considered as a way to gauge potential alternative economic opportunities. This paper offers recommendations to policymakers for alternative economic development strategies needed to create new jobs and diversify the state’s economy, and highlights the importance of transition assistance at the federal level.

    This Green Helmet Project is intended to suppress generation of environment polluting substances in association with coal utilization in Thailand by demonstrating and improving the proliferation infrastructure for the clean coal technology to be used widely in Thailand. The project is also intended to serve for stabilized assurance of energies for Japan. The demonstration project related to briquette manufacturing facilities executed as one of the 'Projects to support introduction of environment friendly coal utilization system' is intended to manufacture at low cost a briquette which is low in odor, free of smoke, and suppressed largely of sulfur oxide generation. The briquette is made by adding clayish minerals, sulfur, a fixing agent and a binder into brown coal being a low grade coal. The project implements proliferation of the technology to reduce environmental load associated with coal utilization in developing countries according to the situation and needs of the counterpart countries. The present project has performed the site surveys and guidance of operation and maintenance techniques as follow-up works of the demonstration project having been completed by cooperation between Japan and Thailand. It is considered that what had been intended in the beginning has been achieved sufficiently. (NEDO)

    Highlights: • A real option-based model for the valuation of CDM projects is proposed. • This study investigates the impact of energy policies on the value of CDM projects. • Level of target emission and its schedule should be carefully designed. • Government subsidy facilitates the implementation of CDM projects. • Period for free emission allowance prevents promoting CDM projects. - Abstract: Emission trading has been considered a primary policy tool for emission reduction. Governments establish national targets for emission reduction and assign emission reduction goals to private entities to accomplish the targets. To attain the goal, private entities should perform offset projects that can produce emission credits or buy emission credits from the market. However, it is not easy for private entities to decide to implement the projects because energy policies associated with emission trading keep changing; thus, the future benefits of the offset projects are quite uncertain. This study presents a real option-based model to investigate how uncertain energy policies affect the financial viability of an offset project. A case study showed that the establishment of a target emission was attractive to the government because it could make the CDM project financially viable with a small amount of government subsidy. In addition, the level of the government subsidy could determine the investment timing for the CDM project. In this context, governments should be cautious in designing energy policies, because even the same energy policies could have different impacts on private entities. Overall, this study is expected to assist private entities in establishing proper investment strategies for CDM projects under uncertain energy policies

    1980-07-01

    An abandoned underground coal mine waste area in Macoupin County, Illinois, has been reclaimed for demonstration and research purposes near the city of Staunton. According to federal law, end uses of reclaimed coal mines must be determined in part by local concerns. This study examined local residents' preferences for land uses and their social and economic evaluations of reclamation at the Macoupin County site. Personal interviews with 119 residents revealed preferences for recreational use of the demonstration area; however, responses were probably influenced by prior awareness of land-use intentions. Generally, very positive evaluations of the reclamation were received. Willingness to pay for reclamation appears to be linked to fulfillment of desired recreational uses on the site and socioeconomic status of the respondent. In general, the research results provide further evidence that the value of abatement of environmental damage from mining is recognized and supported in economic terms at the public level.

    Full Text Available This paper analyses the applicability of well-known risk management methodologies in energy efficiency projects in the industry. The possibilities of application of the selected risk management methodology are demonstrated within the project of the plants for injecting pulverized coal into blast furnaces nos. 1 and 2, implemented by the company US STEEL SERBIA d.o.o. in Smederevo. The aim of the project was to increase energy efficiency through the reduction of the quantity of coke, whose production requires large amounts of energy, reduction of harmful exhaust emission and increase productivity of blast furnaces through the reduction of production costs. The project was complex and had high costs, so that it was necessary to predict risk events and plan responses to identified risks at an early stage of implementation, in the course of the project design, in order to minimise losses and implement the project in accordance with the defined time and cost limitations.

    In early 1991 British Coal reviewed its existing personnel and manpower planning systems and concluded they were inadequate for the future needs of the business. British Coal`s strategy to continue to improve productivity required payroll and personnel related systems which could support new flexible working hours and variable shifts. This strategy would enable machine running time to be increased, leading to improved productivity levels. The Corporation chose to install a distributed, integrated computer system, code named `Compass` to devolve many of the responsibilities for the management and payment of the industrial workforce from Corporate headquarters` functions to all its collieries. The system consists of eight main software systems: an on-line, real-time time and attendance system; a ristering system; a colliery personnel system; a strategic manpower planning system; a local data capture system; a central, core payroll system; a corporate personnel database; and a fail-safe, resilience system. The article describes the technology used and discusses the benefits of the system which started operations in autumn 1993. 3 figs.

    Full Text Available Corporate social responsibility (CSR in mining areas has increased momentum especially in countries like India where it has been made mandatory. The primary objective of this paper is to document actual social challenges of mining in field areas and find out how companies in the coal sector can work in a systematic manner to achieve uplift of affected communities. The first part of the paper draws evidence from three different bodies of literature, i.e. CSR and coal mining, capacity building and livelihood generation in mining areas. We try to converge the literature to propose a novel framework for livelihood generation work through capacity building with the help of CSR investments. The paper also documents a live case of planning and the implementation of capacity building activities in Muriadih coal mines in the Jharkhand state of India and offers lessons to both business and policy makers. The proposed framework has only been experimented in a local context, yet has the potential to be replicated in other mining areas.

    The present Japan-China joint development project is intended to study liquefaction performance of different types of Chinese coals, select coal types suitable for coal liquefaction, and serve for enhancement in the coal liquefaction technologies employed by the Chinese side. Since a small continuous testing device has been installed in fiscal 1982 and begun with the trial operation in March 1983, the liquefaction test has been performed for about five years, and is scheduled to continue another three years. Chinese coals produced in seven provinces and two autonomous regions have been subjected to the coal type selection, on which discussions were given for liquefying reaction characteristics by using autoclave testing and small continuous testing devices. As a result, circulation tests were performed by the end of fiscal 1987 on five coal types, namely Beisu coal, Texgxian coal, Xianfeng coal, Shenmu coal, and Meihekou coal. Data were acquired during the circulation and at the equilibrium. Comparison of the results of tests on these five coal types with the results having been acquired from the 0.1-t/d BSU in Japan before modification verified the result being nearly reasonable.

    1993-01-01

    Indonesia's coal mining sector is expanding rapidly. Much of the increase in coal production since the mid-1980s has been exported. Indonesian coal mining companies have large expansion programs and continuing strong export growth is projected for the remainder of the 1990s. The low mining costs of indonesian coal, together with proximity to Asian markets, mean that Indonesia is well placed to compete strongly with other thermal coal exporters and win market share in the large and expanding thermal coal market in Asia. However, there is significant uncertainty about the likely future level of Indonesia's exportable surplus of coal. The government's planned expansion in coal fired power generation could constrain export growth, while the ability of producers to meet projected output levels is uncertain. The purpose in this article is to review coal supply and demand developments in Indonesia and, taking account of the key determining factors, to estimate the level of coal exports from Indonesia to the year 2000. This time frame has been chosen because all currently committed mine developments are expected to be on stream by 2000 and because it is difficult to project domestic demand for coal beyond that year. 29 refs., 8 tabs., 7 figs

    Today, tourism represents one of the backbones of Croatian economy and one of the main factors of its growth. Combined with catering trade sector, tourism represents a significant energy consumer that has the tendencies of future growth. Since services sector, which tourism–catering trade sector is a part of, is not yet well described regarding future energy balances it would be very interesting to see how could possible future growth in tourism influence energy consumption of the services sector in Croatia. Through this paper long term energy demand projections of tourism–catering trade sector were studied with special emphasis on future growth of tourism in Croatia as well as different mechanisms that might lead to certain energy savings. Bottom-up approach was chosen as the most suitable one since it allows better quantification of different measures, technological or legal, that would influence future energy demand. Downside of this approach is extensive input data that is required to analyse and model future energy demand which is roughly divided into heating/cooling section and all other consumption. Results show that additional energy savings in the tourism–catering trade sector are possible if careful and rational demand side planning is in place. -- Highlights: ► Future energy demand of Croatian touristm–catering trade sector has been modelled. ► Model is roughly divided into two basic modes (heating/cooling and all other consumption). ► Different factors influencing future energy demand were implemented into the model. ► Possibilities for energy efficiency improvements have been presented.

    2015-07-01

    This paper reviews the environmental problems, impacts and risks associated with the generation and disposal of produced water by the emerging coal seam gas (CSG) industry and how it may be relevant to Australia and similar physical settings. With only limited independent research on the potential environmental impacts of produced water, is it necessary for industry and government policy makers and regulators to draw upon the experiences of related endeavours such as mining and groundwater extraction accepting that the conclusions may not always be directly transferrable. CSG is widely touted in Australia as having the potential to provide significant economic and energy security benefits, yet the environmental and health policies and the planning and regulatory setting are yet to mature and are continuing to evolve amidst ongoing social and environmental concerns and political indecision. In this review, produced water has been defined as water that is brought to the land surface during the process of recovering methane gas from coal seams and includes water sourced from CSG wells as well as flowback water associated with drilling, hydraulic fracturing and gas extraction. A brief overview of produced water generation, its characteristics and environmental issues is provided. A review of past lessons and identification of potential risks, including disposal options, is included to assist in planning and management of this industry.

    Highlights: • Sizing of biomass fired cogeneration block is performed for existing heating plant. • Mathematical model for cogeneration block optimisation is presented. • Impact of financial support mechanisms on optimal solution is discussed. • Influence of short term variations of prices and support intensity is presented. • Different design parameters are suggested by economic and technical quality indices. - Abstract: The paper presents results of design parameters optimisation of a wood chips fired steam boiler based heat and power block in a sample project of coal fired municipal heating plant modernisation. The project assumes the conversion of the heating plant into a dual fuel heat and power plant. The problem that is presented is selection of cogeneration block structure and thermodynamic parameters taking into account financial support mechanisms for cogeneration and renewable energy technologies. There are examined energy conversion and financial performances of the project. The results show that without the financial support the project is not profitable although it generates savings of primary energy of fossil fuels. If an administrative incentives are applied the optimal technical solution is different than suggested by energy conversion efficiency or fossil fuel savings. Financial calculations were performed for Polish marked conditions in the years 2011 and 2014 showing the impact of relatively short term variations of prices and support intensity on optimal plant design parameters

    The opportunity cost for carbon dioxide (CO 2 ) emissions has become a new factor influencing investments in heat and power production capacity globally, and in particular in countries with a greenhouse gas emissions trading system, such as the European Union Emissions Trading Scheme (EU ETS). There is a considerable power capacity investment need in the coming decades in Finland, in Europe and globally. As the economic lifetime of an investment in heat and power capacity typically ranges from 20-40 years, 'carbon finance' and the EU ETS therefore introduce a considerable and fundamental price risk to the investment problem. In Europe, the price risk is present in all investments and divestments of power production licences or capacity, be it a green-field plant, a retrofit of an existing plant or an acquisition. The objective of the INVIS research project was to extend the knowledge on strategic implications of emissions trading in investments into heat and power generation. This report gives an overview on the main findings of the project. The focus of INVIS project was on (1) quantitative investment appraisal and (2) methods rather than tools or parameter values. Particular attention in the INVIS project was paid to the incorporation of emissions trading in new methods of investment appraisal, which aim at taking into account the value of real options, rights to postpone or revise decisions. The EU ETS modifies the quantitative investment appraisal of heat and power plants directly through the emission allowance price and the number of free allowances and indirectly through impacts on output prices, input prices, taxation, and subsidies. From the risk perspective, the most problematic impact seems to be the regulatory uncertainty in the number of free allowances, which can turn out to be a barrier for investment in fossil-fuel-fired thermal power plants - even combined-cycle gas turbines. The emission allowance price is a stochastic variable, which implies it is

    1989-07-01

    This paper describes the achievements in the Sunshine Project in fiscal 1988 in studies on coal liquefaction. The liquefaction mechanisms may be conceived to work in the following three manners: radicals produced by spontaneous bond and cleavage of coal molecules draw out hydrogen from the donor and stabilize it; bond, cleavage and stabilization due to hydrogenation from the donor to coal aromatic nucleus; and cleavage and stabilization due to work of active hydrogen discharged from the donor. How these mechanisms contribute to composition of the products depends on coals, liquefying conditions, and reactivity of the donor. Selection of the donor solvent requires design by which high liquefaction yield can be obtained with small amount of solvent. The oil plus asphaltene yield could have been approached to the ideal value through the moving liquefaction of gaseous phase hydrogen and catalyst-free hydrogen, with the 4HFL to coal ratio at 1.5 to 1. The gaseous phase hydrogen was found effective in reducing 4HFL. Liquefaction residual oil manufactured from Morwell brown coal subjected to BCL was hydrogenated in single stage or two stages to compare and discuss the solvent sorting constituents, reactivity of CLVR, and how the catalytic activity deteriorates. The cause for the catalyst deterioration was elucidated, and considerations were given on catalysts and reaction conditions for lightening and refining of CLVR. (NEDO)

    Full Text Available Currently, there are considerable discrepancies between China’s central government and some local governments in attitudes towards coal to liquids (CTL technology. Energy return on investment (EROI analysis of CTL could provide new insights that may help solve this dilemma. Unfortunately, there has been little research on this topic; this paper therefore analyses the EROI of China’s Shenhua Group Direct Coal Liquefaction (DCL project, currently the only DCL commercial project in the world. The inclusion or omission of internal energy and by-products is controversial. The results show that the EROIstnd without by-product and with internal energy is 0.68–0.81; the EROIstnd (the standard EROI without by-product and without internal energy is 3.70–5.53; the EROIstnd with by-product and with internal energy is 0.76–0.90; the EROIstnd with by-product and without internal energy is 4.13–6.14. Furthermore, it is necessary to consider carbon capture and storage (CCS as a means to control the CO2 emissions. Considering the added energy inputs of CCS at the plant level, the EROIs decrease to 0.65–0.77, 2.87–3.97, 0.72–0.85, and 3.20–4.40, respectively. The extremely low, even negative, net energy, which may be due to high investments in infrastructure and low conversion efficiency, suggests CTL is not a good choice to replace conventional energy sources, and thus, Chinese government should be prudent when developing it.

    With the development of world's business and trade, coal has become a large part of the import and export goods in the international market. The total amount of coal trade has risen a lot. China is rich in coal resources. According to the estimate made by some experts, the reserve which has been explored recently could be exploited hundreds of years. China's output of raw coal has risen a lot during the past forty years. China coal industry has developed rapidly since the 1980s. It is possible for China to become a big coal export country since it has rich resources and increasing output. The paper suggests four steps which must be taken to expand coal exports in China: improve the level of management and administration of coal mines so as to raise the economic benefit; the follow-up production capacity of the present mines must be enhanced rapidly; step up construction of new large-scale mines; and China's coal washing capacity must be improved speedily since the low capacity has seriously influenced the improvement of coal quality.

    Purpose - Indiana is listed among the top ten coal states in the USA and annually mines about 35 million short tons (million tons) of coal from the vast reserves of the US Midwest Illinois Coal Basin. The implementation and commercialization of clean coal technologies is important to the economy of the state and has a significant role in the state's energy plan for increasing the use of the state's natural resources. Coal is a substantial Indiana energy resource and also has stable and relatively low costs, compared with the increasing costs of other major fuels. This indigenous energy source enables the promotion of energy independence. The purpose of this paper is to outline the significance of clean coal projects for achieving this objective. Design/methodology/approach - The paper outlines the clean coal initiatives being taken in Indiana and the research carried out at the Indiana Center for Coal Technology Research. Findings - Clean coal power generation and coal for transportation fuels (coal-to-liquids - CTL) are two major topics being investigated in Indiana. Coking coal, data compilation of the bituminous coal qualities within the Indiana coal beds, reducing dependence on coal imports, and provision of an emissions free environment are important topics to state legislators. Originality/value - Lessons learnt from these projects will be of value to other states and countries.

    The 10 MW Demonstration of the Gas Suspension Absorption (GSA) program is a government and industry co-funded technology development. The objective of the project is to demonstrate the performance of the GSA system in treating a 10 MW slipstream of flue gas resulting from the combustion of a high sulfur coal. This project involves design, fabrication, construction and testing of the GSA system. The Project Performance and Economics Report provides the nonproprietary information for the ``10 MW Demonstration of the Gas Suspension Absorption (GSA) Project`` installed at Tennessee Valley Authority`s (TVA) Shawnee Power Station, Center for Emissions Research (CER) at Paducah, Kentucky. The program demonstrated that the GSA flue-gas-desulfurization (FGD) technology is capable of achieving high SO{sub 2} removal efficiencies (greater than 90%), while maintaining particulate emissions below the New Source Performance Standards (NSPS), without any negative environmental impact (section 6). A 28-day test demonstrated the reliability and operability of the GSA system during continuous operation. The test results and detailed discussions of the test data can be obtained from TVA`s Final Report (Appendix A). The Air Toxics Report (Appendix B), prepared by Energy and Environmental Research Corporation (EERC) characterizes air toxic emissions of selected hazardous air pollutants (HAP) from the GSA process. The results of this testing show that the GSA system can substantially reduce the emission of these HAP. With its lower capital costs and maintenance costs (section 7), as compared to conventional semi-dry scrubbers, the GSA technology commands a high potential for further commercialization in the United States.

    Under the 1990 Clean Air Act Amendments (CAAA), scrubbing and emission allowance trading will play complementary roles. This paper reviews Phase I announced strategies and presents projections of technology controls, coal switching and industry-wide SO 2 removal costs under different assumptions about trading. The principal uncertainties characterizing today's planning environment are discussed -- ranging from changing expectations for fuel costs to swings in allowance prices and questions about regulation and new operating procedures. Economic forecasting is difficult. A clearer picture of Phase 2 strategies is emerging from EPRI's integrated analysis of fuel, technology and allowance markets -- based on collaboration between A. Van Horn and K. White (management consultants) and T. Hewson (Energy Ventures Analysis). About half the SO 2 reductions required in Phase 2 are likely to come from technology controls and half from coal switching. With trading, the highest cost open-quotes scrubsclose quotes and open-quotes switchesclose quotes can be avoided, more upgrading of low-cost scrubbing is expected, and the role of switching grows to a small extent. Additional benefits from trading, averaging and banking allowances are: better sequencing of technology controls, less stringent specs for equipment, and added flexibility/risk-sharing opportunities in contract arrangements

    The paper summed up the FY 1999 results of the survey conducted based on the agreement on the Tanjung Enim IV coal exploration project which was concluded between NEDO and Indonesia's Ministry of Mining Energy. The survey was made for an area of approximately 40km{sup 2} which is a north block of the south Arahan region, Tanjung Enim, South Sumatra, Indonesia. To grasp the succession of strata/rock facies/geological structure and the state of existence of the coal seams to be drilled, surveys were conducted on ground surface and boreholes. A total of 10 holes was test-drilled, and all the boreholes were physically logged. As a result of the survey, each of A1, A2, B, C and E coal seams was confirmed as main seams. A1, A2 and B seams are low in ash and sulfur contents with heating values of approximately 4,800 kcal/kg, C seam is high in sulfur content, and E seam is high in heating value, 6,000 kcal/kg. As coal seams for open pit mining, existence of A, B and C seams is expected which lay in the shallow part from ground surface to sea level of 0m and in the range of depth of approximately 100m. The proved coal reserves of these coals were estimated at 189 million tons. (NEDO)

  14. The Indonesian coal industry

    International Nuclear Information System (INIS)

    Cook, A.; Daulay, B.

    2000-01-01

    In this comprehensive article the authors describe the origins and progress of the Indonesian coal industry and the role it plays, and will play, in the domestic energy scene and world coal trade. In the '80s, the Indonesian coal industry laid the basis for major expansion such that coal production rose from under a million tonnes in 1983 to 10.6 million tonnes in 1990, 50.9 million tonnes by 1996 and 61.2 million tonnes in 1992. At the same time, exports have increased from 0.4 million tonnes to 44.8 million tonnes. Current export levels are higher than originally expected, due in part to a slow down in the construction of electric power stations and a partial switch to natural gas. This has slowed the rate at which domestic coal demand has built up. The majority of coals currently exported are low rank steam coals, but some of the higher rank and very low ash coals are used for blast furnace injection, and a very small proportion may even be used within coking blends, even though they have poor coking properties. The Indonesian coal industry has developed very rapidly over the last six years to become a significant exporter, especially within the ASEAN context. The resources base appears to be large enough to support further increases in production above those already planned. It is probable that resources and reserves can be increased above the current levels. It is likely that some reserves of high value coals can be found, but it is also probable that the majority of additions to reserves will be lower in rank (and therefore quality) compared with the average of coals currently being mined. Reserves of qualities suitable for export will support that industry for a considerable period of time. However, in the longer term, the emphasis of production will increasingly swing to the domestic market

    This program is aimed at establishment of the techniques for milling of brown coal treated by primary dehydration and slurry adjustment, and secondary hydration plant, as part of the project for developing the techniques for liquefaction of brown coal. Brown coal (Australian Yallourn coal) treated by primary dehydration, solvents (creosote and decrystallized anthracene), and catalysts are used as the stock samples, to investigate the coal characteristics with respect to milling crushability, dehydration and liquefaction reactivity, and the slurries are prepared by changing coal charge rate, solvent and preparation temperature, to collect the data regarding, e.g., coal concentration, coal particle size, moisture level and liquefaction reactivity. It is found that milling crushability tends to decrease as coal charge rate or solvent/coal ratio increases whether creosote or decrystallized anthracene is used as the solvent. Milling crushability is unaffected by slurry preparation temperature. Content of residual moisture in the slurry decreases to 1% or less, when slurry preparation temperature is increased to 100 degrees C or higher. Liquefaction reactivity of the slurry shows slight dependence on slurry preparation temperature, when it is increased to 180 degrees C. (NEDO)

    This paper describes the achievements in the Sunshine Project in fiscal 1992 in studies on improving the efficiency of coal gasification. Three kinds of coals were gasified under the atmosphere of hydrogen, He or CO2 by using the TPR method. The sulfur removing rate varies depending on coals even under the same reaction atmosphere, and so does the degree of influence of the atmospheric gases depending on coals. Very little effect of the atmospheric gases was found on the sulfur removing rate in Taiheiyo and Wandoan coals. While Tatung coal presents the same removing rate under the atmosphere of He and CO2, it shows 1.8 times greater removing rate under the hydrogen atmosphere. Generation patterns for H{sub 2}S and COS also vary depending on coal types and atmospheric gases. Inorganic sulfur shows the same behavior in the reaction process regardless of coal type and atmosphere, but organic sulfur behaves differently. The sulfur removing rate is determined by how easily the organic sulfur can be removed, which attributes to the difference in kinds and structures of organic sulfur compounds in the coal, together with the gas generation patterns. In order to discuss gasification of char, investigations were performed on effects of coal types and heat treatment temperatures, with regard to the gasification characteristics that can be estimated from the industrial and element analyses.

    2001-01-01

    In this paper we demonstrate that the institutional arrangement (or: design) of Joint Implementation (JI) and the Clean Development Mechanism (CDM) has a decisive impact on their cost-effectiveness. We illustrate our arguments by statistically analyzing the costs from 94 Activities Implemented Jointly (AIJ) pilot phase projects as well as by adjusting these data on the basis of simple mathematical formulas. These calculations explicitly take into account the institutional differences between JI (sinks, no banking) and the CDM (banking, no sinks) under the Kyoto Protocol and also show the possible effects on credit costs of alternative design options. However, our numerical illustrations should be viewed with caution, because AIJ is only to a limited extent representative of potential future JI and CDM projects and because credit costs are not credit prices. Some of the main figures found in this study are: an average cost figure per unit of emission reduction for AIJ projects of 46 dollar per ton of carbon dioxide equivalent ($/Mg CO 2 -eq), an average potential JI credit cost figure which is lowered to 37 $/Mg CO 2 -eq by introducing banking and an average of 6 $/Mg CO 2 -eq per credit for potential low-cost CDM projects which includes sinks. However, at CoP6 in November 2000 in The Hague (The Netherlands), the Parties to the Framework Convention on Climate Change (FCCC) did not (yet) reach consensus on the institutional details of the project-based mechanisms, such as the possible arrangement of early JI action or the inclusion of sinks under the CDM. 55 refs

    Coal is and will remain the world's most abundant and widely distributed fossil fuel. Burning coal, however, can pollute and it produces carbon dioxide. Clean coal technologies address this problem. The widespread deployment of pollution-control equipment to reduce sulphur dioxide, Nox and dust emissions from industry is just one example which has brought cleaner air to many countries. Since the 1970s, various policy and regulatory measures have created a growing commercial market for these clean coal technologies, with the result that costs have fallen and performance has improved. More recently, the need to tackle rising CO2 emissions to address climate change means that clean coal technologies now extend to include those for CO2 capture and storage (CCS). This short report from the IEA Coal Industry Advisory Board (CIAB) presents industry's considered recommendations on how to accelerate the development and deployment of this important group of new technologies and to grasp their very signifi cant potential to reduce emissions from coal use. It identifies an urgent need to make progress with demonstration projects and prove the potential of CCS through government-industry partnerships. Its commercialisation depends upon a clear legal and regulatory framework,public acceptance and market-based financial incentives. For the latter, the CIAB favours cap-and-trade systems, price supports and mandatory feed-in tariffs, as well as inclusion of CCS in the Kyoto Protocol's Clean Development Mechanism to create demand in developing economies where coal use is growing most rapidly. This report offers a unique insight into the thinking of an industry that recognises both the threats and growing opportunities for coal in a carbon constrained world.

    This final report presents the research work carried out on the Coal Surface Control for Advanced Physical Fine Coal Cleaning Technologies project, sponsored by the US Department of Energy, Pittsburgh Energy Technology Center (DOE/PETC). The project was to support the engineering development of the selective agglomeration technology in order to reduce the sulfur content of US coals for controlling SO[sub 2] emissions (i.e., acid rain precursors). The overall effort was a part of the DOE/PETCs Acid Rain Control Initiative (ARCI). The overall objective of the project is to develop techniques for coal surface control prior to the advanced physical fine coal cleaning process of selective agglomeration in order to achieve 85% pyrite sulfur rejection at an energy recovery greater than 85% based on run-of-mine coal. The surface control is meant to encompass surface modification during grinding and laboratory beneficiation testing. The project includes the following tasks: Project planning; methods for analysis of samples; development of standard beneficiation test; grinding studies; modification of particle surface; and exploratory R D and support. The coal samples used in this project include three base coals, Upper Freeport - Indiana County, PA, Pittsburgh NO. 8 - Belmont County, OH, and Illinois No. 6 - Randolph County, IL, and three additional coals, Upper Freeport - Grant County- WV, Kentucky No. 9 Hopkins County, KY, and Wyodak - Campbell County, WY. A total of 149 drums of coal were received.

    In the course of a research project sponsored by the State of North Rhine-Westphalia the mine surveying methods used when measuring deformation on open cut batters were further developed, by taking into account the special conditions prevailing in open cuts, to such an extent that the essential monitoring of soil movements can be carried out reliably and promptly. As an integral part of an optimised, accurate geodetic measurement of points, the direct measurement of longitude across the open cut was introduced as a rapid measuring method. The aerophotogrammetric measurement of points is practically as accurate as terrestrial surveying. The author describes the prototype of an automatically operated instrument system for the monitoring of points. In conclusion he also stresses that the first promising advance has already been made as regards the sufficiently accurate monitoring of rock movements in boreholes.

  9. Coal: Less than lackluster

    International Nuclear Information System (INIS)

    1994-01-01

    Not many in the world coal industry will remember 1993 as a good year. The reasons for the poor state of affairs were first the weak economic climate, and second, the energy glut. For the first time after expanding steadily since the 70s, seaborne trade in hard coal fell by about 4% to 350M mt. Steam coal accounted for a good half of this volume. While demand continued to rise in the newly industrialized countries of the Pacific area, imports into Europe of both coking coal and steam coal fell sharply. The United States, CIS, and Canada had to accept substantial losses of export volume. Australia, as well as South Africa, Colombia, and Indonesia consolidated their market positions and Poland, too, recorded high volumes available for export. The positive news came from Australia, where in mid-December the New South Wales coal industry reported an increase in the net profit after tax from $A83M (about $55M) to $A98M (about $126M) in 1992/1993. This success was however ascribed less to an improvement in the fundamental mining indicators than to the fall in the Australian dollar and the lowering of corporate tax. The reduction in capital investment by 26% down to $A330M (after the previous year when it had also been cut by 25%) is seen by the chairman of the NSW Coal Assoc. as not auguring well for the industry's ability to meet the forecast growth in demand to the year 2000

    This paper describes the achievements in the Sunshine Project in fiscal 1991 on research of coal liquefying catalysts and a method for analyzing liquefied oil. Alkalis and alkali earth metals present during coal liquefied oil hydrogenation treatment deteriorate the activity remarkably as an effect of metal deposition from an Mo-based catalyst on the activity deterioration. Discussions were given on hydrogenating decomposition paths for bi-cyclic compounds by using reaction of model substances. Preliminary discussions were given jointly under the Japanese and Canadian technical cooperation on enhancing the quality of co-treated oil in the coal liquefaction, and on catalysts used therein. A 1-t/d PSU circulating solvent was studied to support the NEDO's bituminous coal liquefaction program. Analyses were carried out on acenaphthenes, biphenyls, phenanthrenes, and anthracenes in the oil liquefied from Wandoan coal. Discussions were given on CoMo/Al{sub 2}O{sub 3} on the effects of catalyst concentrations and particle sizes in the coal liquefying reaction. In order to elucidate different non-covalently bonded high-order structures of coal polymer assemblies, chemical treatment was applied to coals under a relatively mild condition (room temperature to 150 degrees C). Chemical structures as a result of the non-covalent bond in the coals were investigated from change due to the treatment in the pyridine extraction characteristics. (NEDO)

    This paper describes the achievements in the Sunshine Project in fiscal 1991 on research of coal liquefying catalysts and a method for analyzing liquefied oil. Alkalis and alkali earth metals present during coal liquefied oil hydrogenation treatment deteriorate the activity remarkably as an effect of metal deposition from an Mo-based catalyst on the activity deterioration. Discussions were given on hydrogenating decomposition paths for bi-cyclic compounds by using reaction of model substances. Preliminary discussions were given jointly under the Japanese and Canadian technical cooperation on enhancing the quality of co-treated oil in the coal liquefaction, and on catalysts used therein. A 1-t/d PSU circulating solvent was studied to support the NEDO's bituminous coal liquefaction program. Analyses were carried out on acenaphthenes, biphenyls, phenanthrenes, and anthracenes in the oil liquefied from Wandoan coal. Discussions were given on CoMo/Al{sub 2}O{sub 3} on the effects of catalyst concentrations and particle sizes in the coal liquefying reaction. In order to elucidate different non-covalently bonded high-order structures of coal polymer assemblies, chemical treatment was applied to coals under a relatively mild condition (room temperature to 150 degrees C). Chemical structures as a result of the non-covalent bond in the coals were investigated from change due to the treatment in the pyridine extraction characteristics. (NEDO)

    In 2003 the May/June issue of CoalTrans International speculated that coal liquefaction would become viable due to falling coal prices. This has not proved the case but the sustained high oil price is sparking new interest. A survey by Energy Intelligence and Marketing Research during November 2005 revealed a growth in the number of projects under development or at the feasibility stage. The article reports projects in China, the USA, Australia, New Zealand, the Philippines and India. China is commissioning the first wave of large liquefaction plants. The key question is whether other countries, particularly the USA, will follow.

In a report on a 'current utilization status and effectiveness of a non-destructive electromagnetic vibrator shock source,' an electromagnetic vibrator shock source out of several new coal exploration technologies which are combinations of test boring and seismic prospecting is taken up, and is compared, in terms of technical feature and cost effectiveness, with the seismic reflection survey technique that uses an explosive shock source, and then a conclusion is reported that an electromagnetic vibration shock source method is superior. Using the new electromagnetic method, a seismic wave frequency is so chosen as to be suitable for a given depth. Since it is non-destructive and emits less noise, it is expected that it will serve in various fields other than coal mining. (NEDO)

    The survey was finished in the final fiscal year (FY 2000) of the Tanjung Enim IV Coal Exploration Project between Japan and Indonesia, and a report was summarized on the preliminary coal mining plan. In the design of the optimum mining area and pit, in terms of 3 cases of coal price of $8, $10, and $12/ton, the pit design was made considering rivers, houses, power transmission lines, etc., and the actual coal yield was asked. In the case of coal price of $8/ton, the actual coal yield in pit was 315 million tons in north block and 171 million tons in south block. In the case of coal price of $10/ton, pits are expandable in north block, but not in south block. For all the pit shapes designed, long-term mining plans were worked out. In each of the cases of coal production amount of 1 million, 3 million and 5 million tons, indicated were secular changes in overburden amount and coal quality because of the difference in mining direction. Further studies were made on the deposition plan, simulation of models of mining heavy machines, coal mine facilities, economical efficiency of coal mines, etc. (NEDO)

  1. Coal resources availability in Botswana

    1990-01-01

    This paper reports that Southern Africa, and Botswana in particular, is well-endowed with relatively large reserves of coal. The existence of coal in Botswana has been known since the end of the last century. Exploration activities by the Geological Survey and the private sector led to the discovery of major deposits and by the late 1960s reserves capable of supporting a mine at Morupule for the domestic market has been confirmed. The oil crises of 1973-74 and 1978-79 stimulated increased interest in coal exploration the world over and Botswana attracted several private sector companies looking for coal that could be traded on the international market. As a result vast resources and reserves of low to medium quality bituminous coal, suitable for the export market, were proved. Resources amounting to 21,680 million tonnes of in situ coal had been revealed by 1987. Reserves of possible economic exploitation are estimated at 10,180 million tonnes in two coal field areas, namely the Morupule Coal Field and the Mmamabula Coal Field. Since the collapse of oil prices and consequently coal prices in the mid-1980s, enthusiasm for coal exploration has plummeted and relatively little prospecting has taken place. The coal occurs within the Upper Carboniferous to Jurassic Karoo Supergroup which underlies some 60 percent of the country's land surface. The western part of the country is mantled by the Kalahari beds, a top layer of unconsolidated sands masking bedrock geology. Although coal seams have been intersected in boreholes in this western area, most exploration activity has taken place in the eastern part of the country where the Morupule and Mmamabula coal fields are located. It is in the east that most of the population is concentrated and infrastructure has been developed

    Coal, the world's most abundant fossil fuel, is very important to the world's economy. It represents about 70% of the world's fossil energy reserves. It produces about 27% of the world's primary energy, 33% of the world's electricity, and it is responsible for about $21 billion in coal trade - in 1990, 424 million tons were traded on the international market. And, most importantly, because of its wide and even distribution throughout the world, and because of its availability, coal is not subject to the monopolistic practices of other energy options. How coal can meet future fuel demand in an economical, efficient and environmentally responsive fashion, with particular reference to the new technologies and their US applications is discussed.

    This report examines current technologies and those likely to be used to produce cleaner coal and coal products, principally for use in power generation and metallurgical applications. Consideration is also given to coal production in the leading coal producing countries, both with developed and developing industries. A range of technologies are considered. These include the coal-based liquid fuel called coal water mixture (CWM) that may compete with diesel, the production of ultra-clean coal (UCC) and coal liquefaction which competes with oil and its products. Technologies for upgrading coal are considered, especially for low rank coals (LRC), since these have the potential to fill the gap generated by the increasing demand for coal that cannot be met by higher quality coals. Potential advantages and downsides of coal upgrading are outlined. Taking into account the environmental benefits of reduced pollution achieved through cleaner coal and reduced transport costs, as well as other positive aspects such as a predictable product leading to better boiler design, the advantages appear to be significant. The drying of low rank coals improves the energy productively released during combustion and may also be used as an adjunct or as part of other coal processing procedures. Coal washing technologies vary in different countries and the implications of this are outlined. Dry separation technologies, such as dry jigging and electrostatic separation, are also described. The demonstration of new technologies is key to their further development and demonstrations of various clean coal technologies are considered. A number of approaches to briquetting and pelletising are available and their use varies from country to country. Finally, developments in upgrading low rank coals are described in the leading coal producing countries. This is an area that is developing rapidly and in which there are significant corporate and state players. 81 refs., 32 figs., 3 tabs.

    This report describes the geologic setting for the Deep Saline Reservoirs and Coal Seams in the Ohio River Valley CO{sub 2} Storage Project area. The object of the current project is to site and design a CO{sub 2} injection facility. A location near New Haven, WV, has been selected for the project. To assess geologic storage reservoirs at the site, regional and site-specific geology were reviewed. Geologic reports, deep well logs, hydraulic tests, and geologic maps were reviewed for the area. Only one well within 25 miles of the site penetrates the deeper sedimentary rocks, so there is a large amount of uncertainty regarding the deep geology at the site. New Haven is located along the Ohio River on the border of West Virginia and Ohio. Topography in the area is flat in the river valley but rugged away from the Ohio River floodplain. The Ohio River Valley incises 50-100 ft into bedrock in the area. The area of interest lies within the Appalachian Plateau, on the western edge of the Appalachian Mountain chain. Within the Appalachian Basin, sedimentary rocks are 3,000 to 20,000 ft deep and slope toward the southeast. The rock formations consist of alternating layers of shale, limestone, dolomite, and sandstone overlying dense metamorphic continental shield rocks. The Rome Trough is the major structural feature in the area, and there may be some faults associated with the trough in the Ohio-West Virginia Hinge Zone. The area has a low earthquake hazard with few historical earthquakes. Target injection reservoirs include the basal sandstone/Lower Maryville and the Rose Run Sandstone. The basal sandstone is an informal name for sandstones that overlie metamorphic shield rock. Regional geology indicates that the unit is at a depth of approximately 9,100 ft below the surface at the project site and associated with the Maryville Formation. Overall thickness appears to be 50-100 ft. The Rose Run Sandstone is another potential reservoir. The unit is located approximately 1

    The low-temperature carbonization process of coal is a technology to produce high grade reformed coal corresponding to bituminous coal and coal oil corresponding to heavy oil from subbituminous coal and supply them at prices close to the present market ones. From viewpoints of diversified sources and multiple export harbors, an initial-stage survey was conducted of the whole flow from new development of undeveloped mining areas in the northwest of Sumatra, Indonesia to bringing by ships to Japan of products reformed by LFC process of the US SGI`s low-temperature carbonization technology. Clean coal prepared after mining is produceable at a little higher than $12. At processing ability of 10,000 tons/day of raw coal, production is expected of approximately 5,700 tons/day of solid products of more than 6,500 kcal/kg and approximately 1,000 tons/day of low sulfur C heavy oil class oil. The finished cost of solid products is about $25/ton, which becomes about $40/ton at the harbor price in Japan. In conclusion, the project to enhance the quality of subbituminous coal by the low-temperature carbonization is promising as a total system. 10 refs., 54 figs., 30 tabs.

    This report documents the results of two system related analyses to support the Exploration Technology Development Program (ETDP) Energy Storage Project. The first study documents a trade study to determine the optimum Li-ion battery cell capacity for the ascent stage battery for the Altair lunar lander being developed under the Constellation Systems program. The battery cell capacity for the Ultra High Energy (UHE) Li-ion battery initially chosen as the target for development was 35 A-hr; this study concludes that a 19.4 A-hr cell capacity would be more optimum from a minimum battery mass perspective. The second study in this report is an assessment of available low temperature Li-ion battery cell performance data to determine whether lowering the operating temperature range of the Li-ion battery, in a rover application, could save overall system mass by eliminating thermal control system mass normally needed to maintain battery temperature within a tighter temperature limit than electronics or other less temperature sensitive components. The preliminary assessment for this second study indicates that the reduction in the thermal control system mass is negated by an increase in battery mass to compensate for the loss in battery capacity due to lower temperature operating conditions.

    Five energy companies in the Netherlands want to build additional coal-fired power plants: Essent and Nuon, the German company RWE and E.ON and the Belgian company Electrabel. Coal-fired power plants emit 70 percent more CO2 than gas-fired power plants. Especially because of the threat to the climate Greenpeace believes that no more coal-fired power plants should be built. In this publication Greenpeace explores the pollution, the working conditions and human rights with regard to the exploitation of coal. That has been elaborated for the three countries from which Dutch energy companies import coal: South Africa, Colombia and Indonesia. In addition to information about the origin of coal also insight is given into the coal market (stocks and use), the enormous coal transport and the world trade [nl

    Full Text Available Introduction: Economic effects of membership in the WTO in recent years, has been one of the most important issues for Iranian economy. If Iran joins the WTO, in this process, tariff reduction in agricultural sector will be one of the policies which has to be employed. Therefore, investigating economic effects of tariff reduction or even its elimination in this sector will be necessary in running effective policies to minimize the probabilistic losses of accession. Tariffs on agricultural products in Iran are determined merely on the basis of annual country economy, and have no long term strategy. Government is just obliged to impose effective tariffs on agricultural products imports, in order to protect local productions. On the other hand, according to the census of population and housing, the share of agricultural sector in employment has reduced during the past decade. Moreover, Iran central bank information indicated the reduction in the share of agricultural sector in GDP for the past decade. Declining the share of agriculture in production and employment, considering the high number of university graduates in the field of agriculture along with rising unemployment rate of this group, motivated this study to investigate the effect of tariff reduction in this sector on macroeconomic variables. Materials and Methods: This study analyzed the welfare effects of import tariffs reduction in agricultural sector from Iran most important commercial partners and vice versa, using the Global Trade Analysis Project (GTAP, based on computable general equilibrium (CGE model. Moreover, the effects of tariffs reduction, is investigated on output, price level and transfer of production factors between different economic sectors. In order to simulate the above model, we used GTAP version 8 which covers 57 commodities and 113 regions with economic information of these regions. This model uses Social Accounting Matrix of countries as data information. Our

    In relation to the circulating fluidized bed boiler which reduces the amount of sulfur oxides emitted in coal utilization, a verification project was carried out on installation of the equipment and spread activity in China and the Philippines contributing to the control of environmental pollutant associated with coal utilization and the effective use of energy. At the Fanshan area, installed was a 10t/h internal circulating fluidized bed boiler. At the performance test, coal includes around 7% of impurities such as stone, and the impurities should be excluded continuously at the time of actual run. Therefore, the boiler efficiency had to be changed from 89.5% to 85.8%. Further, power generation facilities have not yet been finished, and the overall operation of boiler turbine has not been executed. At the Zibo area, a 30t/h external circulating fluidized bed boiler was installed. The boiler efficiency reached 86.1%, over the targeted value. At the Batangas area in the Philippines, a 10t/h internal circulating fluidized bed boiler was installed. The boiler efficiency reached 85.8%, over the designed value. About the coal produced in the Philippines, slagging was feared, but the combustion state was favorable. 82 figs., 21 tabs.

    It is an important issue to expand stable coal supply areas for Japan, especially to assure stable supply of overseas coals. The investigations on geological structures in foreign countries perform surveys on geological structures in overseas coal producing countries and basic feasibility studies. The investigations select areas with greater business risks in coal producing countries and among private business entities. The geological structure investigations were carried out on China, Indonesia and Malaysia and the basic feasibility studies on Indonesia during fiscal 1994. The basic coal resource development investigations refer to the results of previous physical explorations and drilling tests to develop practical exploration technologies for coal resources in foreign countries. The development feasibility studies on overseas coals conduct technological consultation, surface surveys, physical explorations, and trial drilling operations, and provide fund assistance to activities related thereto. Fiscal 1994 has provided fund assistance to two projects in Indonesia and America. Fund loans are provided on investigations for development and import of overseas coals and other related activities. Liability guarantee for development fund is also described.

    Swedish consumption of coal and coke during 1991 and trends in technology, environment and market aspects of coal use are reported. Steam coal use in the heating sector was unchanged from 1991, 1.2 Mtons. Reduced consumption in smaller district heating units (due to conversion to biofuels and gas) was compensated by increased use for power generation in cogeneration plants. Coal consumption in industry fell 0.10 Mton to 0.84 Mton due to lower production in one industry branch. Import of steam coal was 1.1 Mton (down 0.5 Mton from 1990) since new rules for strategic reserves allowed a reduction of stocks. During the last five years stocks have been reduced by 2 Mtons. Import of metallurgical coal was 1.6 Mton, unchanged from 1990. The report also gives statistics for the coal using plants in Sweden, on coal R and D, and on emission laws for coal firing.

    2003-01-01

    Watershed-based trading and offset systems are being developed to improve policy-maker?s and regulator?s ability to assess nonpoint source impacts in watersheds and to evaluate the efficacy of using market-incentive programs for preserving environmental quality. An overview of the history of successful and failed trading programs throughout the United States suggests that certain political, economic, and scientific conditions within a temporal and spatial setting help meet water quality standards. The current lack of spontaneous trading among dischargers does not mean that a marketable permit trading system is an inherently inefficient regulatory approach. Rather, its infrequent use is the result of institutional and informational barriers. Improving and refining the earth science information and technologies may help determine whether trading is a suitable policy for improving water quality. However, it is debatable whether or not environmental information is the limiting factor. This paper reviews additional factors affecting the potential for instituting a trading policy. The motivation for investigating and reviewing the history of offsets and trading was inspired by a project in the preliminary stages being developed by U.S. Geological Survey Western Geographic Science Center and the Environmental Protection Agency Region IX. An offset feasibility study will be an integrated, map-based approach that incorporates environmental, economic, and statistical information to investigate the potential for using offsets to meet mercury Total Maximum Daily Loads in the Sacramento River watershed. A regional water-quality offset program is being studied that may help known point sources reduce mercury loading more cost effectively by the remediation of abandoned mines or other diffuse sources as opposed to more costly treatment at their own sites. An efficient offset program requires both a scientific basis and methods to translate that science into a regulatory decision

    Within Germany, subsidies to the domestic coal industry are raising taxes, increasing electricity prices, constraining industry competitiveness and causing distortions to resource allocation decisions. Coal assistance policies raise the costs of German industry, particularly those which use coal and electricity. In the case of assistance to steaming coal production, subsidies are less explicit, making the direct cost of continued support to the industry less obvious. If Germany deregulated its coal industry, it would become a major coal importer, conceivably importing as much as 60 Mt a year. Such an increase in import demand would raise world coal trade volume significantly. The impact of liberalisation on world coal prices would depend on the extent and timing of liberalisation and the responsiveness of suppliers to the increased import demand. 13 refs., 5 figs., 2 tabs.

At each of the project implementation sites, lectures were given on technical matters, technical know-how was exchanged, and study tours were organized to facilities concerned, which meant to promote the diffusion of the related technologies throughout China and, eventually, to contribute to the enhancement of environmental protection. The main subjects at the seminars included the introduction of GAP (green aid plan) projects in China, introduction of the outlines of technologies related to the model projects, verification and achievements, latest trends, and measures for the diffusion of the technologies. Study tours were made, and videos were shown relating to the local conditions. Every one of the seminars was successfully attended by 60-70 participants. (NEDO)

    The paper summarized the results of the surveys in the final fiscal year (FY 2000) and in the past five years of the Tanjung Enim IV Coal Exploration Project between Japan and Indonesia. In FY 2000, conducted in the South Arahan area were the surface reconnaissance (50km+ACI-2), boring survey (11 holes, 1,847m), borehole physical logging (11 holes), reflection method seismic survey (3 traverse lines), pumping test, coal analysis (112 specimens), etc. As a result of the exploration/study made during 5 years, coal reserves in the South Arahan area were 223 million tons in north block (proved coal reserves: 213 million tons) and 332 million tons (proved coal reserves: 303 million tons) in south block. The coal in the area is in the depth of {+-}0m from surface, and the coal reserve is enough for large scale open pit mining. Further, coal reserves in the Banjarsari area were 442 million tons (proved coal reserves: 330 million tons) in the whole area and 223 million tons (proved coal reserves: 214 million tons) in the syncline part. About the syncline part promising as that for open pit mining, the overburden ratio was divided into three for calculation: 2:1, 3:1 and 4:1 or below. (NEDO)

  1. Projections of air toxic emissions from coal-fired utility combustion: Input for hazardous air pollutant regulators

    1993-01-01

    The US Environmental Protection Agency (EPA) is required by the 1990 CAAA to promulgate rules for all ''major'' sources of any of these HAPs. According to the HAPs section of the new Title III, any stationary source emitting 10 tons per year (TPY) of one HAP or 25 TPY of a combination of HAPs will be considered and designated a major source. In contrast to the original National Emission Standards for Hazardous Air Pollutants (NESHAP), which were designed to protect public health to ''an ample margin of safety,'' the new Title III, in its first phase, will regulate by industrial category those sources emitting HAPs in excess of the 10/25-TPY threshold levels, regardless of health risks. The trace elements normally associated with coal mineral matter and the various compounds formed during coal combustion have the potential to produce hazardous air toxic emissions from coal-fired electric utilities. Under Title III, the EPA is required to perform certain studies, prior to any regulation of electric utilities; these studies are currently underway. Also, the US Department of Energy (DOE) maintains a vested interest in addressing those energy policy questions affecting electric utility generation, coal mining, and steel producing critical to this country's economic well-being, where balancing the costs to the producers and users of energy with the benefits of environmental protection to the workers and the general populace remains of significant concern

    Following a legal agreement with the European Union (EU), Philip Morris International (PMI) commissions a yearly report ('Project Star', PS) on the European illicit cigarette trade from KPMG, the global accountancy firm. Review of PS 2010 report. Comparison with data from independent sources including a 2010 pan-European survey (N=18,056). Within PS, data covering all 27 EU countries are entered into a model. While the model itself seems appropriate, concerns are identified with the methodologies underlying the data inputs and thus their quality: there is little transparency over methodologies; interview data underestimate legal non-domestic product partly by failing to account for legal cross-border sales; illicit cigarette estimates rely on tobacco industry empty pack surveys which may overestimate illicit; and there is an over-reliance on data supplied by PMI with inadequate external validation. Thus, PMI sales data are validated using PMI smoking prevalence estimates, yet PMI is unable to provide sales (shipment) data for the Greek islands and its prevalence estimates differ grossly from independent data. Consequently, comparisons with independent data suggest PS will tend to overestimate illicit cigarette levels particularly where cross-border shopping is frequent (Austria, Finland, France) and in Western compared with Eastern European countries. The model also provides data on the nature of the illicit cigarette market independent of seizure data suggesting that almost a quarter of the illicit cigarette market in 2010 comprised PMI's own brands compared with just 5% counterfeited PMI brands; a finding hidden in PMI's public representation of the data. PS overestimates illicit cigarette levels in some European countries and suggests PMI's supply chain control is inadequate. Its publication serves the interests of PMI over those of the EU and its member states. PS requires greater transparency, external scrutiny and use of independent data. Published by the BMJ

    Having the Mining Industry Restructuring Public Corporation located in the city of Katowice, Poland as the counterpart, a feasibility study has been executed on a project to utilize coal bed gas for power generation. Selected for the study are the 'Budryk coal mine' owned by KWK 'Budryk' Coal Company and the 'Pniowek coal mine' owned by Jastrzebie Coal Company. Since the Pniowek coal mine can utilize the whole quantity of recovered methane by 2001, the Budryk coal mine was selected as the object of the project. As a result of the trial calculation on the economy when the new gas power plant is installed in the Budryk coal mine, the energy substitution effect was found to equal to a power amount at transmission terminal of 6 MWh/year. Furthermore, when proliferation effect is taken into consideration, an enormous effect can be expected if new coal mines are developed and the existing cola mines will go further deeper, because the Silesian coal mine presently has the coal resource quantity of 57 billion tons and the annual gas discharge quantity of 750 million m{sup 3}. Therefore, if the technologies to recover, manage and utilize the gas are established at the Budryk coal mine, a large effect leading to an aspiration would be expected under the current situation of the structural reorganization under which the Polish coal companies are placed.

    The US Department of Energy is performing comprehensive assessments of toxic emissions from eight selected coal-fired electric utility units. This program responds to the Clean Air Act Amendments of 1990, which require the US Environmental Protection Agency (EPA) to evaluate emissions of hazardous air pollutants (HAPs) from electric utility power plants for Potential health risks. The resulting data will be furnished to EPA utility power plants and health risk determinations. The assessment of emissions involves the collection and analysis of samples from the major input, process, and output streams of each of the eight power plants for selected hazardous Pollutants identified in Title III of the Clean Air Act. Additional goals are to determine the removal efficiencies of pollution control subsystems for these selected pollutants and the Concentrations associated with the particulate fraction of the flue gas stream as a function of particle size. Material balances are being performed for selected pollutants around the entire power plant and several subsystems to identify the fate of hazardous substances in each utility system. Radian Corporation was selected to perform a toxics assessment at a plant demonstrating an Innovative Clean Coal Technology (ICCT) Project. The site selected is Plant Yates Unit No. 1 of Georgia Power Company, which includes a Chiyoda Thoroughbred-121 demonstration project.

    The U.S. Geological Survey (USGS) conducted the National Coal Quality Inventory (NaCQI) between 1999 and 2005 to address a need for quality information on coals that will be mined during the next 20-30 years. Collaboration between the USGS, State geological surveys, universities, coal burning utilities, and the coal mining industry plus funding support from the Electric Power Research Institute (EPRI) and the U.S. Department of Energy (DOE) permitted collection and submittal of coal samples for analysis. The chemical data (proximate and ultimate analyses; major, minor and trace element concentrations) for 729 samples of raw or prepared coal, coal associated shale, and coal combustion products (fly ash, hopper ash, bottom ash and gypsum) from nine coal producing States are included. In addition, the project identified a new coal reference analytical standard, to be designated CWE-1 (West Elk Mine, Gunnison County, Colorado) that is a high-volatile-B or high-volatile-A bituminous coal with low contents of ash yield and sulfur, and very low, but detectable contents of chlorine, mercury and other trace elements.

  10. The economics of international coal markets

    Paulus, Moritz

    2012-07-13

    In the scope of four related essays this thesis analyses the Chinese domestic coal sector and coal trade policies and their respective impact on international steam coal trade economics. In particular, the thesis investigates the role of domestic transport infrastructure investment policies as well as Chinese coal export and import controls and the potential exertion of market power through such trade instruments. For this purpose, several spatial equilibrium models have been developed that enable simulation runs to compare different policy scenarios. These models also permit ex-post analyses to empirically test hypotheses of non-competitive market conduct of individual players under the assumption of Cournot behaviour. These model-based analyses yield, among others, the following findings: If coal is converted into electricity early in the Chinese energy supply chain, worldwide marginal costs of supply are substantially lower than if coal is transported via railway. This can reduce China's dependence on international imports significantly. Allocation of welfare changes, particularly in favour of Chinese consumers while rents of international producers decrease. If not only seaborne trade but also interactions and feedbacks between domestic coal markets and international trade markets are accounted for, trade volumes and prices of a China - Indonesia duopoly fit the real market outcome best in 2008. Real Chinese export quotas have been consistent with simulated exports under a Cournot-Nash strategy. Uncertainties with regard to future Chinese coal demand and coal sector policies generate significant costs for international investors and lead to a spatial and temporal reallocation of mining and infrastructure investments. The potential exertion of Chinese demand side market power would further reduce the overall investment activity of exporters.

  15. Modeling the international competitiveness of Botswana's coal

    Science.gov (United States)

    Fichani, Khaulani

    Botswana has vast proven deposits of steam coal, which for a long time it has wanted to develop but without much success. The main objectives of this study are: (1) to analyze the time schedule of coal exports likely to be forthcoming from Botswana and the land routes for these exports; (2) to determine the competitiveness of Botswana's coal in the world steam coal markets and (3) to make recommendations on the appropriate policy for the exploitation of this coal. To accomplish these objectives, we construct a model of the seaborne steam coal trade consisting of exporters and importers with a substantial share in this trade. We econometrically estimate the long run marginal cost functions for net exporters and employ these to construct a spatial and dynamic model of the world steam coal trade with elastic supply and inelastic demand. This model is applied to simulate Botswana's competitiveness in this trade over the period 1995 to 2010 from a 1990 base year with a decision criterion that minimizes the sum of discounted capital costs of mine development, variable supply costs, rail and maritime transportation costs. Finally, we employ the model to forecast the likely optimal size of mine, timing of production capacity and choice of export port for Botswana's coal for the years 2005 and 2010. The base year for the forecast is 2000. The simulation results indicate that Botswana's coal would have been competitive in the steam coal markets of Western Europe and Asia. The forecast results indicate that Botswana's coal would also be competitive in these markets in the future. These results are least sensitive to changes in rail transportation and variable supply costs but are sensitive to capital costs for mine development.

Geological engineering problem has large effect on the protection and productivity of underground coal mines. Promotion of long wall mining has contributed to reduction of disasters, however, recently deaths due to roof collapse and wall collapse are on the increase. A roof evaluation technique was developed for adequate selection of mining methods and support design, and its standardization and diffusion are in promotion. Integration and improvement advanced in facility technology because of worldwide integration by acquisition of coal mine facility manufacturers. Introduction of high-power high-capacity facilities is increasing with introduction of large long wall working faces, and development of rear transport system technology and labor saving by remote control are also in promotion according to such trend. As automation and labor saving technology of mining facilities, the automated direction detection and control system by laser and gyroscope is under development. (NEDO)

    The project represents a landmark assessment of the potential of low-NO(sub x) burners, advanced overtire air, and neural-network control systems to reduce NO(sub x) emissions within the bounds of acceptable dry-bottom, wall-fired boiler performance. Such boilers were targeted under the Clean Air Act Amendments of 1990 (CAAA). Testing provided valuable input to the Environmental Protection Agency ruling issued in March 1994, which set NO(sub x) emission limits for ''Group 1'' wall-fired boilers at 0.5 lb/10(sup 6) Btu to be met by January 1996. The resultant comprehensive database served to assist utilities in effectively implementing CAAA compliance. The project is part of the U.S. Department of Energy's Clean Coal Technology Demonstration Program established to address energy and environmental concerns related to coal use. Five nationally competed solicitations sought cost-shared partnerships with industry to accelerate commercialization of the most advanced coal-based power generation and pollution control technologies. The Program, valued at over$5 billion, has leveraged federal funding twofold through the resultant partnerships encompassing utilities, technology developers, state governments, and research organizations. This project was one of 16 selected in May 1988 from 55 proposals submitted in response to the Program's second solicitation. Southern Company Services, Inc. (SCS) conducted a comprehensive evaluation of the effects of Foster Wheeler Energy Corporation's (FWEC) advanced overfire air (AOFA), low-NO(sub x) burners (LNB), and LNB/AOFA on wall-fired boiler NO(sub x) emissions and other combustion parameters. SCS also evaluated the effectiveness of an advanced on-line optimization system, the Generic NO(sub x) Control Intelligent System (GNOCIS). Over a six-year period, SCS carried out testing at Georgia Power Company's 500-MWe Plant Hammond Unit 4 in Coosa, Georgia.

    The revival of coal prices is providing record profits for Australian coal producers. As the world's largest coal exporter, any move in coal prices has significant ramifications for the Australian economy. The coal boom of the mid-1980s resulted in a massive increase in mine capacity and subsequently excess supply. This resulted in the decade between 1990 and 2000 seeing benchmark prices for coking coal in Japan plummeting to $US 39 a tonne (down from around the $US 52 mark) and a price of $US 28 for a tonne of steaming coal. Asia's financial problems, late in the decade coupled with a rapid fall in Asian steel making, also added to our coal export woes. As a result for most of the 1990s, Australia's coal sector delivered inadequate returns, was seen as over-capitalised and suffered from a profound investor indifference. But the sector is now seeing a definite turnaround in fortunes. Prices for thermal coal are on the rise and the benchmark coking coal prices to Asia have also jumped. Market analysts reported the price for contract deliveries of thermal coal in April this year were $US 34.50 ($AUD 69.35) up by $US 5.75 from the same time last year. The increased production is expected on the back of a continued rise in export demand, further improvement in prices, significant improvements in mine productivity, a weak Australian dollar and the probability of new projects and mine extensions going into operation. The improved returns have also flowed into rising valuations for listed coal miners. Over the last year, coal miners such as MIM and Gympie Gold, have delighted in share price gains of 12 per cent and 55 per cent respectively. These sort of performances are being repeated across the Australian industry

    The basic experimental researches were carried out for coal liquefaction by solvolysis. The studied items include hydrogenation conditions for treating the primary liquefied products, asphalt, pitch and model solvents (e.g., anthracene oil) in the presence of a commercial catalyst, solvolysis conditions for finely divided, molten coal using a hydrogenation recycled solvent, hydrotreating solvents, analysis of solvolysis-liquefied products, and liquefaction capacity of fractionated solvents for finely divided, molten coal. The studied items for separation of minerals include settlement at high temperature of the solid residue from the first liquefaction stage, and changed coal particle size distribution as a result of the first-stage liquefaction reactions in the presence of a hydrogenation solvent. The experimental study results indicate that conversion of finely divided molten coal into asphaltenes and preasphaltenes is notably accelerated in the phase-II coal liquefaction process by solvolysis, when a hydrotreating solvent is used for the first stage solvolysis process.

There are no major changes on the horizon that are likely to alter the role of the US as a modest coal supplier to the Asia-Pacific region. The downward trend in US coal exports to Asia is expected to continue over the 1997--2010 period. But economic and policy changes underway in Asia are likely to result in periodic coal shortages, lasting a few months to a year, and short term increased export opportunities for US coal. US coal exports to Asia are projected to fluctuate within the following ranges over the 2000--2010 period: 10--17 million tons in total exports, 6--12 million tons in thermal coal exports, and 4--9 million tons in coking coal exports. The most important role for US coal, from the perspective of Asian coal importing countries, is to ensure a major alternative source of coal supplies that can be turned to in the event of unforeseen disruptions in coal supplies from the Asia-Pacific region or South Africa. However, the willingness of consumers to pay a premium to ensure US export capacity is declining, with increased emphasis on obtaining the lowest cost coal supplies

    for irrigation can already be documented. Due to drier summers induced by climate change, this phenomenon is expected to gain more importance in the future. Related to water quantity and quality it is crucial to think about the diverging interests between the supply of the population with national agricultural products and the preservation of the water bodies, their ecological value and their other ecosystem services (e.g. drinking water supply). The project AProWa attempts to elucidate trade-offs of national goals for water protection and agricultural production in Switzerland by involving stakeholders from agricultural administration (Federal Office for Agriculture, FOAG), agricultural research (Agroscope), water research (Swiss Federal Institute of Aquatic Science and Technology, Eawag) and environmental protection (Federal Office for the Environment, FOEN). This is done by applying multi-criteria decision analysis facilitating consensus regarding goals and possible activities and alternatives to reach these goals. This is followed by an evaluation of main conflicts and prioritized research gaps. We present preliminary results from workshops and interdisciplinary discussion groups that encompass an objectives hierarchy reflecting agricultural production and water conservation goals. Furthermore, an inventory of agricultural practices and water protection measures is presented, enabling their evaluation for the provision of agricultural production while sustaining aquatic ecosystems.

    Development has been carried out on a Chinese coal liquefaction technology jointly by Japan and China. The Japanese side fabricated and built a small continuous testing equipment. Shenbei coal produced in Liaoning Province, Tienju coal produced in Gansu Province and Shenmu coal produced in Shaanxi Province were used as test sample coals. These coals were crushed, washed with water, sorted, dried, pulverized below 100 mesh, and used as the test samples. For catalysts, a reagent Fe{sub 2}O{sub 3} and S as an auxiliary catalyst made in China were used. Anthracene oil freed from crystal was used as a starting solvent when making one-through operation and recycling operation. Hydrogen used had purity of 99.5% or higher. The current fiscal year has performed smoothly to the end either of the one-through operation or the solvent circulating operation on RUN-2200, 2300 (Chenbei coal) and 2,400, 2500 (Tienju coal). Operation of 2600, 2700 (Shenmu coal) experienced noise in the stirrer of the reactor, and leakage of the circulating gas from the recycled gas compressor. In addition, the differential pressure during operating the last run has increased to 50 k, when the temperature and pressure were reduced, and substances clogging the reactor inlet line were removed. Three kinds of the liquefied oils were brought back to Japan for detailed analyses. (NEDO)

  7. Permit trading and credit trading

    This paper compares emissions trading based on a cap on total emissions (permit trading) and on relative standards per unit of output (credit trading). Two types of market structure are considered: perfect competition and Cournot oligopoly. We find that output, abatement costs and the number...... of firms are higher under credit trading. Allowing trade between permit-trading and credit-trading sectors may increase in welfare. With perfect competition, permit trading always leads to higher welfare than credit trading. With imperfect competition, credit trading may outperform permit trading....... Environmental policy can lead to exit, but also to entry of firms. Entry and exit have a profound impact on the performance of the schemes, especially under imperfect competition. We find that it may be impossible to implement certain levels of total industry emissions. Under credit trading several levels...

    This paper describes the achievements in the Sunshine Project in fiscal 1990 on research of coal liquefying catalysts and a method for analyzing liquefied oil. Regenerating deteriorated hydrogenating catalysts for coal liquefied oil makes the restoration non-reversible because of residual sulfate. Discussions were given on the regenerating mechanisms. It was found that adding Ru enhances activity of an Ni-Mo catalyst for hydrogenating denitrification and hydrogenation. In studying coal liquefying reaction, a basic study was performed to analyze a catalytic mechanism in the hydrogenating decomposition. Sequential lightening reaction process is being analyzed at molecular levels on coal, preasphaltene, asphaltene and oil. Investigations were carried out on hydrogenating denitrification, deoxygenation, ring opening, decomposition mechanism and catalytic action. A study on precision structural analysis has begun on PSU circulating solvent as a NEDO bituminous coal liquefaction supporting technology. In fiscal 1990, a preliminary study was performed to identify the overall image of the composition of the Wandoan coal liquefied oil. Detailed analysis was executed on naphthalenes and their hydrides. This paper also describes composition analysis and reaction analysis by using the GC/MS ion chromatogram method. It also dwells on the study on catalyst utilizing systems. (NEDO)

    Full Text Available District heating technologies should be efficient, effective and environmentally friendly. The majority of the communal heating systems in Poland produce district hot water in coal-fired boilers. A large number of them are considerably worn out, low-efficient in the summer time and will not comply with forthcoming regulations. One of the possible solution for such plants is repowering with new CHP systems or new boilers fuelled with fuels alternative to coal. Optimisation analysis of the target configuration of municipal heat generating plant is analysed in the paper. The work concerns repowering the existing conventional heat generating plant according to eight different scenarios of the plant configuration meeting technical and environmental requirements forecasted for the year of 2035. The maximum demand for heat of the system supplied by the plant is 185 MW. Taking into account different technical configurations on one side, and different energy and fuel prices on the other side, the comparative cost-benefits analysis of the assumed scenarios has been made. The basic economical index NPV (net present value has been derived for each analysed scenario and the results have been compared and discussed. It was also claimed that the scenario with CHP based on ICE engines is optimal.

    This paper describes the achievements in the Sunshine Project in fiscal 1992 in studies on liquefying reaction in coal, and reforming of the products. High conversion rate was attained in the co-treatment of bitumen and Taiheiyo coals by using highly dispersing oil soluble solvent without performing coking, even if the asphaltene concentration is high. When a very highly acidic trifluoromethane sulfonic acid catalyst is used, hydrogenation and conversion to solubilized low molecules is possible even with a solvent having low affinity with coal. Swelling effect by tetralin is remarkable in pulverized coal, and the conversion rate was improved greatly under high-pressure hydrogen. When naphtha of the Wandoan coal liquefied oil is given extraction treatment with base and acid/base, the gas production decreases noticeably when hydrogenating and refining the extracts, resulting in reduced hydrogen consumption and improved oil recovery rate. Furthermore, when the extraction treated naphtha is hydrogenated, denitrification can be achieved completely. Kerosene and light oil liquefied from the Wandoan coal were cracked by fluidity contact, whereas the light gravity product yield due to the decomposition was found low because of containing a great amount of two-ring aromatics. The pressure crystal deposition method using solvent is effective in separation of high-melting point compounds including anthracene from heavy gravity oil. (NEDO)

    The geological survey was carried out which is needed for coal mine design in the Yu Xian coal mine area, Yu Xian coal field, Hebei province, China. The term of survey was 5 years from 1996 to 2000. Activities are mainly for seismic survey and boring survey. Japan was in charge of the seismic survey, and China in charge of the boring survey. Both attained the goal. The results of the activities were summed up in the following 7 items: 1) outline of the survey; 2) general investigation; 3) state of the exploration related materials/machinery; 4) field survey; 5) items of survey; 6) results of the survey; 7) conclusion. In 6), the geological analysis, coal quality survey and coal amount survey were conducted. In the geological analysis, analyzed were the succession of strata, geological structure, and the situation of existence of coal seams. In 7), the following were made clear: geological structure of the survey area, coal seam, coal quality, hydrological geology, other conditions of drilling technology, and coal amount. The coal amount was 328.34 million tons in a total of A/B/C class coals. The total coal amount of Nos. 1 and 5 coal seams was 259.79 million tons, which was 79.1% of the total coal amount in all area. The average thickness of Nos. 1 and 5 coal seams, which are the main minable coal seams, was 3.10m and 2.66m, respectively. (NEDO)

    The report deals mainly with coal consumption, but also gives some information about technology, environmental aspects and markets. Data have been collected by questionnaires or via telephone. The use of steam coal for heating was 0.8 Mtons (down 20% from 1994). Cogeneration plants were the main users. Taxes and environmental reasons cause a reduction of the coal use that will probably continue the next years. Use of steam coal in industry has been constant at a level of 0.7 Mtons. The import of metallurgical coal rests constant at a level of 1.6 Mtons. 1.2 Mtons of coke was produced, and 0.3 Mtons imported. The PFBC-plant at Vaertan, Stockholm used 0.13 Mtons of coal, while some coal fired power plants have been converted to peat and wood fuels. The average price of steam coal imported to Sweden in 1995 was 333 SEK/ton, 6% higher than in 1994. The contract prices for delivery 1996 are about the same as at the end of 1995. All cogeneration plants have some sort of SO 2 removal system, mostly wet-dry. The largest plant, at Vaesteraas, has recently invested in a SCR system for NO x removal. Most other plants are using low NO x burners or SNCR systems, based on ammonia or urea, which reduce the emissions 50 - 70%. Some statistic about the world coal market is also given in the report

    2008-07-01

    Coal is and will remain the world’s most abundant and widely distributed fossil fuel. Burning coal, however, can pollute and it produces carbon dioxide. Clean coal technologies address this problem. The widespread deployment of pollution-control equipment to reduce sulphur dioxide, Nox and dust emissions from industry is just one example which has brought cleaner air to many countries. Since the 1970s, various policy and regulatory measures have created a growing commercial market for these clean coal technologies, with the result that costs have fallen and performance has improved. More recently, the need to tackle rising CO2 emissions to address climate change means that clean coal technologies now extend to include those for CO2 capture and storage (CCS). This short report from the IEA Coal Industry Advisory Board (CIAB) presents industry’s considered recommendations on how to accelerate the development and deployment of this important group of new technologies and to grasp their very signifi cant potential to reduce emissions from coal use. It identifies an urgent need to make progress with demonstration projects and prove the potential of CCS through government-industry partnerships. Its commercialisation depends upon a clear legal and regulatory framework,public acceptance and market-based financial incentives. For the latter, the CIAB favours cap-and-trade systems, price supports and mandatory feed-in tariffs, as well as inclusion of CCS in the Kyoto Protocol’s Clean Development Mechanism to create demand in developing economies where coal use is growing most rapidly. This report offers a unique insight into the thinking of an industry that recognises both the threats and growing opportunities for coal in a carbonconstrained world.

    Between 1990 and 2007, 15 southern white (Ceratotherium simum simum) and black (Diceros bicornis) rhinoceroses on average were killed illegally every year in South Africa. Since 2007 illegal killing of southern white rhinoceros for their horn has escalated to >950 individuals/year in 2013. We conducted an ecological–economic analysis to determine whether a legal trade in southern white rhinoceros horn could facilitate rhinoceros protection. Generalized linear models were used to examine the socioeconomic drivers of poaching, based on data collected from 1990 to 2013, and to project the total number of rhinoceroses likely to be illegally killed from 2014 to 2023. Rhinoceros population dynamics were then modeled under 8 different policy scenarios that could be implemented to control poaching. We also estimated the economic costs and benefits of each scenario under enhanced enforcement only and a legal trade in rhinoceros horn and used a decision support framework to rank the scenarios with the objective of maintaining the rhinoceros population above its current size while generating profit for local stakeholders. The southern white rhinoceros population was predicted to go extinct in the wild El Grano de los Datos de Costo Económico con Referencia Espacial y de Beneficio a la Biodiversidad y la Efectividad de una Estrategia de Determinación de Costos Resumen Entre 1990 y 2007, en promedio fueron cazados ilegalmente cada año 15 rinocerontes sureños blancos (Ceratotherium simum simum) y negros (Diceros bicornis) en Sudáfrica.

    in equipment for burning pellets instead of coal. In Linkoeping waste of rubber is mixed with coal. Also Soederenergi AB has rebuilt their three coal boilers and replaced 100 % of the coal by peat and wood fuels. Coal is a reserve fuel. Several co-generation plants like Linkoeping, Norrkoeping, Uppsala and Oerebro use both coal and forest fuels. The use of coal is then concentrated to the electricity production. The average price of steam coal imported in Sweden in 1998 was 370 SEK/ton or the same as in 1997. For the world, the average import price fell about 6 USD/ton to 32 USD/ton. The price fall was concentrated to the 4th quarter. The prices have continued to fall during 1999 as a result of the crisis in Asia but are now stabilising as a result of increasing oil prices. All Swedish plants meet their emission limits of dust, SO{sub 2} and NO{sub x}, given by county administrations or concession boards. The co-generation plants have all some sort of SO{sub 2}-removal system. Mostly used is the wet-dry method. The biggest co-generation plant, in Vaesteraas, has recently invested in a catalytic NO{sub x}-cleaning system type SCR, which is reducing the emission level 80-90 %. Most other plants are using low NO{sub x}- burners or injection systems type SNCR, based on ammonium or urea, which are reducing the emissions 50-70 %. A positive effect of the recently introduced NO{sub x}-duties is a 60 % reduction compared to some years ago, when the duties were introduced. World hard coal production was about 3 700 tons in 1998, a minor decrease compared to 1997. The trade, however, has increased about 3 % to 520 mill tons. The coal demand in the OECD-countries has increased about 1,7 % yearly during the last ten years. The coal share of the energy supply is about 20% in the OECD-countries and 27% in the whole world. Several sources estimate a continuing growth during the next 20 years in spite of an increasing use of natural gas and nuclear power. The reason is a strong

In the development of a plasma sub-burner and the basic research for its verification, a pulverized coal burning plasma sub-burner is designed and fabricated, a basic burning experiment is conducted for the plasma sub-burner, and plasma stabilization in a pulverized coal flow is simulated. In the verification study of the ignition by the plasma sub-burner in a pulverized coal-fired furnace, it is found that the newly-developed plasma sub-burner satisfies the prescribed operating conditions in the system and that the ignition of pulverized coal takes place across the air ratio range of 0.5-1.5 when pulverized coal is fed to the sub-burner. It is also found that NOx is reduced a great deal when a plasma operating on an orifice gas of air or nitrogen is generated in a gas which contains NOx. (NEDO)

    In this paper, a primal dual programming model of international coking coal trade is constructed to test for non-competitive market behaviour. World trade in 1996 is simulated under perfect competition and various non-competitive market structures. Statistical tests are used to compare simulated trade flows with actual data. Assuming Cournot-Nash behaviour, an all consumer oligopsony market structure is preferred to alternative models. Under an all consumer oligopsony world coking coal prices and trade are lower than under perfect competition. Under an oligopsonistic structure welfare gains from productivity increases in Australian coal mines might largely accrue to coal buyers

    1994-01-01

    The Clean Coal Technology Program is a government and industry cofunded effort to demonstrate a new generation of innovative coal processes in a series of full-scale showcase`` facilities built across the country. Begun in 1986 and expanded in 1987, the program is expected to finance more than $6.8 billion of projects. Nearly two-thirds of the funding will come from the private sector, well above the 50 percent industry co-funding expected when the program began. The original recommendation for a multi-billion dollar clean coal demonstration program came from the US and Canadian Special Envoys on Acid Rain. In January 1986, Special Envoys Lewis and Davis presented their recommendations. Included was the call for a 5-year, $5-billion program in the US to demonstrate, at commercial scale, innovative clean coal technologies that were beginning to emerge from research programs both in the US and elsewhere in the world. As the Envoys said: if the menu of control options was expanded, and if the new options were significantly cheaper, yet highly efficient, it would be easier to formulate an acid rain control plan that would have broader public appeal.

    Indonesia's fire and haze problem is increasingly being ascribed to large-scale forest conversion and land clearing activities making way for pulpwood, rubber and oil palm plantations. Fire is the cheapest tool available to small holders and plantation owners to reduce vegetation cover and prepare and fertilize extremely poor soils. Fires that escaped from agricultural burns have ravaged East Kalimantan forests on the island of Borneo during extreme drought periods in 1982-1983, 1987, 1991, 1994 and 1997-1998. Estimates based on satellite data and ground observations are that more than five million hectares were burned in East Kalimantan during the 1997/1998 dry season. Not only were the economic losses and ecological damage from these surface fires enormous, they ignited coal seams exposed at the ground surface along their outcrops.Coal fires now threaten Indonesia's shrinking ecological resources in Kutai National Park and Sungai Wain Nature Reserve. Sungai Wain has one of the last areas of unburned primary rainforest in the Balikpapan-Samarinda area with an extremely rich biodiversity. Although fires in 1997/1998 damaged nearly 50% of this Reserve and ignited 76 coal fires, it remains the most valuable water catchment area in the region and it has been used as a reintroduction site for the endangered orangutan. The Office of Surface Mining provided Indonesia with the capability to take quick action on coal fires that presented threats to public health and safety, infrastructure or the environment. The US Department of State's Southeast Asia Environmental Protection Initiative through the US Agency for International Development funded the project. Technical assistance and training transferred skills in coal fire management through the Ministry of Energy and Mineral Resource's Training Agency to the regional offices; giving the regions the long-term capability to manage coal fires. Funding was also included to extinguish coal fires as

    Coal liquefaction produces new and clean energy by performing hydrogenation, decomposition and liquefaction on coal under high temperatures and pressures. NEDO has been developing bituminous coal liquefaction technologies by using a 150-t/d pilot plant. It has also developed quality improving and utilization technologies for liquefied coal, whose practical use is expected. For developing coal gasification technologies, construction is in progress for a 200-t/d pilot plant for spouted bed gasification power generation. NEDO intends to develop coal gasification composite cycle power generation with high efficiency and of environment harmonious type. This paper summarizes the results obtained during fiscal 1994. It also dwells on technologies to manufacture hydrogen from coal. It further describes development of technologies to manufacture methane and substituting natural gas (SNG) by hydrogenating and gasifying coal. The ARCH process can select three operation modes depending on which of SNG yield, thermal efficiency or BTX yield is targeted. With respect to promotion of coal utilization technologies, description is given on surveys on development of next generation technologies for coal utilization, and clean coal technology promotion projects. International coal utilization and application projects are also described. 9 figs., 3 tabs.

    This paper describes the achievements in the Sunshine Project in fiscal 1992 on research of coal liquefying catalysts and a method for analyzing liquefied oil. Oxidative regeneration was performed on an Ni-W based waste catalyst used in reforming (hydrogenating) coal liquefied light oil fraction. If the regeneration can be done with low oxygen partial pressure and step-wise temperature rise, the activity after the regeneration can be restored to the level of a new catalyst, with sulfate production being suppressed. Model reaction was discussed by changing the amount of W and Mo carried by alumina. Suppressing the carrying amount can control the hydrogenation activity and the hydrogenating decomposition activity. Comparison was given on compositions of woods and such hydrogenation products as peat and coal. Analysis was performed on composition of the circulating solvent used in the NEDO bituminous coal liquefying PSU. In the initial stage of the operation, the solvent had higher concentrations in the groups of compounds not having alkyl groups, and compounds having the alkyl groups increased in the end of the operation. Discussions were given also on index materials to control the operation of solvent hydrogenating process. Efficient preparation conditions were discussed on an iron sulfide particulate catalyst that utilizes surface reaction of a solid metal while mechanical impact such as vibration is being given. Effects of the catalyst concentration in coal liquefaction were experimented by using oil soluble molybdenum, wherein no change was found in the reaction mechanism. (NEDO)

    This project addresses DOE's interest in advanced concepts for controlling emissions of air toxics from coal-fired utility boilers. We are determining the feasibility of developing a biochemical process for the precombustion removal of substantial percentages of 13 inorganic hazardous air pollutant (HAP) precursors from coal. These HAP precursors are Sb, As, Be, Cd, Cr, Cl, Co, F, Pb, Hg, Mn, Ni, and Se. Although rapid physical coal cleaning is done routinely in preparation plants, biochemical processes for removal of HAP precursors from coal potentially offer advantages of deeper cleaning, more specificity, and less coal loss. Compared to chemical processes for coal cleaning, biochemical processes potentially offer lower costs and milder process conditions. Pyrite oxidizing bacteria, most notably Thiobacillusferrooxidans, are being evaluated in this project for their ability to remove HAP precursors from U.S. coals

    The article briefly profiles the coal market for non-utility generation (NUG). Coal consumption by NUGs, currently estimated at around 6.1 million tons, is projected to reach nearly 13.6 million tons by 1995 and 21.2 million tons by 2000. If the projected growth is achieved the NUG market may become one of the strongest market segments for the coal industry into the next century. 3 figs., 2 tabs

    Underground coal gasification has potential in Alberta. This presentation provided background information on underground coal gasification and discussed groundwater and the Laurus Energy demonstration project. A multi-disciplined approach to project assessment was described with particular reference to geologic and hydrogeologic setting; geologic mapping; and a hydrogeologic numerical model. Underground coal gasification involves the conversion of coal into synthesis gas or syngas. It can be applied to mined coal at the surface or applied to non-mined coal seams using injection and production wells. Underground coal gasification can effect groundwater as the rate of water influx into the coal seams influences the quality and composition of the syngas. Byproducts created include heat as well as water with dissolved concentrations of ammonia, phenols, salts, polyaromatic hydrocarbons, and liquid organic products from the pyrolysis of coal. A process overview of underground coal gasification was also illustrated. It was concluded that underground coal gasification has the potential in Alberta and risks to groundwater could be minimized by a properly designed project. refs., figs.

    One of the major technology challenges in the next decade will be to develop means of using coal imaginatively as a source of chemicals and in a more energy-efficient manner. The Clean Air Act will help to diminish the acid rain but will not reduce CO 2 emissions. The Department of Energy (DOE) is fostering many innovations that are likely to have a positive effect on coal usage. Of the different innovations in the use of coal fostered by DOE, two are of particular interest. One is the new pressurized fluid bed combustion (PFBC) combined-cycle demonstration. The PFBC plant now becoming operational can reduce SO 2 emissions by more than 90% and NO x emissions by 50-70%. A second new technology co-sponsored by DOE is the Encoal mild coal gasification project that will convert a sub-bituminous low-BTU coal into a useful higher BTU solid while producing significant amounts of a liquid fuel

    After enduring contract price cuts over the past two years of almost 17% for thermal coal and 23% for hard coking coal, the New South Wales coal industry is looking forward to a reversal of fortune for 2001. Increased export demand, improved prices, significant improvements in mine site productivity, a weak Australian dollar and the probability of a number of new projects or extensions progressing to development are likely to result in an increase in NSW saleable production to around 110 million tonnes (Mt) in 2000-01. Sharply weaker coal prices over the past two years, intensified international competition and the Asian economic downturn had a negative impact on profitability, investment, exports and employment in the NSW coal industry. As a result, the industry has undergone substantial restructuring. The restructuring process has led to a consolidation in ownership, reduced production costs and improved operational efficiency. The outcome is an industry well positioned to take advantage of the positive market conditions and one likely to experience levels of profitability not achieved over the past few years

  19. New Source Review and coal plant efficiency gains: How new and forthcoming air regulations affect outcomes

    Forthcoming carbon dioxide (CO 2 ) regulations for existing power plants in the United States have heightened interest in thermal efficiency gains for coal-fired power plants. Plant modifications to improve thermal efficiency can trigger New Source Review (NSR), a Clean Air Act requirement to adopt of state-of-the-art pollution controls. This article explores whether existing coal plants would likely face additional pollution control requirements if they undertake modifications that trigger NSR. Despite emissions controls that are or will be installed under the Mercury and Air Toxics Standards (MATS) and Clean Air Interstate Rule (CAIR) or its replacement, 80% of coal units (76% of capacity) that are expected to remain in operation are not projected to meet the minimum NSR requirements for at least one pollutant: nitrogen oxides or sulfur dioxide. This is an important consideration for the U.S. Environmental Protection Agency and state policymakers as they determine the extent to which CO 2 regulation will rely on unit-by-unit thermal efficiency gains versus potential flexible compliance strategies such as averaging, trading, energy efficiency, and renewable energy. NSR would likely delay and add cost to thermal efficiency projects at a majority of coal units, including projects undertaken to comply with forthcoming CO 2 regulation. - Highlights: • We explore the status of the U.S. coal-fired fleet relative to New Source Review (NSR) requirements. • Modifications to improve thermal efficiency can trigger NSR. • Thermal efficiency gains may also be an important strategy for forthcoming CO 2 regulation. • 80% Of non-retiring coal-fired units are projected not to meet minimum NSR requirements. • NSR is an important consideration for the design of CO 2 regulations for existing plants

    The paper discusses the global energy demand situation as presented at the last World Energy Congress. The total energy demand was calculated for each country and projected to 2100. The paper then discusses the energy situation in the United States, especially the forecasted demand for crude oil and natural gas liquids. Imports will be needed to make up the shortfall in domestic production. The shortfall in conventional petroleum could be supplied by converting coal into liquid fuels. Currently the cost of high quality coal liquids is too high to compete with petroleum, but trends suggest that the price will be competitive in the year 2030 using current technology. Continuing research on coal liquefaction will reduce the price of coal liquids so that coal liquids could play a significant role sooner

    Clean Coal Technology is an arbitrary terminology that has gained increased use since the 1980s when the debate over acid raid issues intensified over emissions of sulfur dioxide and nitrogen oxides. In response to political discussions between Prime Minister Brian Mulroney of Canada and President Ronald Reagan in 1985, the US government initiated a demonstration program by the Department of Energy (DOE) on Clean Coal Technologies, which can be categorized as: 1. precombustion technologies wherein sulfur and nitrogen are removed before combustion, combustion technologies that prevent or lower emissions as coal is burned, and postcombustion technologies wherein flue gas from a boiler is treated to remove pollutants, usually transforming them into solids that are disposed of. The DOE Clean Coal Technology (CCT) program is being carried out with $2.5 billion of federal funds and additional private sector funds. By the end of 1989, 38 projects were under way or in negotiation. These projects were solicited in three rounds, known as Clean Coal I, II, and III, and two additional solicitations are planned by DOE. Worldwide about 100 clean coal demonstration projects are being carried out. This paper lists important requirements of demonstration plants based on experience with such plants. These requirements need to be met to allow a technology to proceed to commercial application with ordinary risk, and represent the principal reasons that a demonstration project is necessary when introducing new technology

    2006-01-01

    Will coal electrical plants be more competitive in the coming years? Answering this one cannot be limited to merely comparing estimates based on reference electricity production costs. The competitiveness of coal will indeed depend on the final product marketed, as the MWhs are not equal: is the purpose to produce base, half-base MWh? Does the electrical equipment structure require flexible MWh (for instance in the event of significant intermittent renewable energy amounts), and therefore plants able to adjust their power rapidly? But the competitiveness of coal will also depend on many factors that will correct reference cost estimates: uncertainties, risks, externalities. These factors will need to be appreciated on a case by case basis. We introduce some of the reasoning used to better appreciate the future competitiveness of coal, and the main factors conditioning it in three contrasting regions of the world: Europe, USA, china.

    This report summarizes state water laws likely to affect the development of coal slurry pipelines. It was prepared as part of a project to analyze environmental issues related to energy transportation systems. Coal slurry pipelines have been proposed as a means to expand the existing transportation system to handle the increasing coal shipments that will be required in the future. The availability of water for use in coal slurry systems in the coal-producing states is an issue of major concern.

    Energy Technology Data Exchange (ETDEWEB)

    1982-04-01

    This study was initiated because of the anticipated rapid growth in trained personnel requirements in bituminous coal mining, and because the industry had already experienced significant problems in recruiting skilled manpower in the course of its employment expansion during the 1970's. Employment in bituminous coal mining is projected to nearly double, from 234,000 in 1977 to 456,000 in 1995, as the net result of a projected threefold increase in coal output to nearly 2.0 billion in 1995 and of an expected significant improvement in overall productivity. A large proportion of current coal mining employees are in occupations which require significant amounts of training for effective work performance. Employment growth to 1955 will be most rapid in those occupations requiring the greatest training or educational preparation. The new training infrastructure which has emerged to meet these needs includes both internal, company-operated training programs and those offered by various external providers. Among the latter are: Vocational schools, community colleges, and university extension departments; public agencies, such as MSHA and state mining departments; coal industry trade associations; and vendors or training consultant groups. The Conference Board survey of coal industry training programs, conducted in late 1979, was designed to provide comprehensive data on the scope of the coal industry's own training activities and on related training issues, based on a mail questionnaire survey addressed to all companies producing 300,000 or more tons per year. The training programs are described with emphasis on time changes, regional effects and implications for a coordinated plan.

    In Europe, international division is in progress as the result of market internationalization, and the coal market is experiencing an increasingly intensive competition in the storm of deregulation. The coal industry of Britain is away from a crisis for the time being, thanks to a new 5-year contract concluded with the electric utilities who are the primary purchasers, but it has to compete with imported coal and natural gas. The industry is also hit by the control imposed on the development of new opencast coal mines. Production is on the decline in the German coal market, which is one the largest in Western Europe, due to reduced subsidies, unfavorable geological conditions, lowered price, etc. The German coal industry is positively striving to exploit coal mines overseas and to export coal mining technologies. In Spain and France, the coal industry is forced to shrink and, in France, there is a plan to terminate coal mining completely in 2005. In Poland, the introduction of market economy has resulted in the influx of low-price coal from Russia etc., and all the Polish mines are now in the red. Its joining the European Union in the near future will further increase the pressure from other nations. It is learned that in Britain, Germany, etc., coal businesses are accelerating their transfer of technology to developing countries and are positively strengthening their presence abroad. (NEDO)

    The report deals with the use of coal and coke during 1996. Some information about techniques, environmental questions and markets are also given. Data have been collected by questionnaires to major users and by telephone to minor users. Preliminary statistical data from SCB have also been used. The use of steam coal for heating purposes during 1996 was 1,2 mill tons and 50% higher than in 1995. The increase is probably temporary and due to high prices of electricity because of lack of water power. The co-generation plants were the main users of coal. The minor plants have increased their use of forest fuels. Probably the use of steam coal will go down in the immediate years both in the heat generating and the co-generation plants. During the top year 1987 coal was used in 18 hotwater plants and 11 co-generation plants. 1996 these figures are 3 and 12. Taxes and environmental reasons explain this trend. The use of steam coal in the industry has been constant at the level 700 000 tons. This level is supposed to be constant or to vary with business cycles. The import of metallurgical coal in 1996 was 1,6 mill tons like the year before. 1,2 mill tons coke were produced. The coke consumption in the industry was 1,5 mill tons. 0,3 mill tons of coke were imported. The average price of steam coal imported in Sweden in 1996 was 340 SEK/ton or 2% higher than in 1995. For the world, the average import price was 51,5 USD/ton, nearly the same as the year before. The contract prices for delivery during 1997 are about equal as the end of 1996.

    2011-07-01

    This report focuses mainly on developments to improve the performance of coal-based power generation technologies, which should be a priority -- particularly if carbon capture and storage takes longer to become established than currently projected. A close look is taken of the major ongoing developments in process technology, plant equipment, instrumentation and control. Coal is an important source of energy for the world, particularly for power generation. To meet the growth in demand for energy over the past decade, the contribution from coal has exceeded that of any other energy source. Additionally, coal has contributed almost half of total growth in electricity over the past decade. As a result, CO2 emissions from coal-fired power generation have increased markedly and continue to rise. More than 70% of CO2 emissions that arise from power generation are attributed to coal. To play its role in a sustainable energy future, its environmental footprint must be reduced; using coal more efficiently is an important first step. Beyond efficiency improvement, carbon capture and storage (CCS) must be deployed to make deep cuts in CO2 emissions. The need for energy and the economics of producing and supplying it to the end-user are central considerations in power plant construction and operation. Economic and regulatory conditions must be made consistent with the ambition to achieve higher efficiencies and lower emissions. In essence, clean coal technologies must be more widely deployed.

    The following report deals with the use of coal and coke during 1997. Some information about technic, environmental questions and markets are also given. Data have been collected by questionnaires to major users and by telephone to minor users. Preliminary statistical data from SCB have also been used. The use of steam coal for heating purposes during 1997 was 730 000 tons and about 500 000 tons lower than in 1996. The extremely high figures of 1996 were due to twice the production of electricity because of lack of hydro power. The co-generation plants were the main users of coal. The minor plants have increased their use of forest fuels. Probably the use of steam coal will go down in the immediate years both in the heat generating and the co-generating plants. Some foreign analysts, however, estimate a doubled use of coal for energy use after 2020 because of the plans to phase out the nuclear power. During the top year 1987 coal was used in 18 hot water plants and 11 co-generation plants. 1997 these figures are 2 and 8. Taxes and environmental reasons explain this trend. The use of steam coal in the industry has been constant at the level 700 000 tons. This level is supposed to be constant or to vary with business cycles. The import of metallurgical coal in 1997 was 1.6 mill tons like the year before. 1.2 mill tons coke were produced. The coke consumption in the industry was 1.5 Mill tons. 0.3 mill tons of coke were imported. Several other plants have plans to replace the coal with forest fuels, waste fuels and NG. Even the biggest plant, Vaesteraas, has plans to build a block for bio fuels. Helsingborg has started to use wood pellets. The pellets replace most of the coal for the heat production in the co-generation plant. Norrkoeping Kraft AB has taken a fluid bed boiler for different fuels in operation, leading to more than half the coal consumption compared with previous years. They have also rebuilt one of their travelling grates for bio fuels. Stockholm

    Present context of the EU Co2 Emission Trading System (EU ETS) from 2008, involves new measures directed towards a large portion of present emissions sources. Currently there is no basis in statistics figures to offset the consequences of these international obligations in SSB models. In the model projections is nevertheless necessary to model both the current instruments and expected future changes in the rules and forms of association. This paper documents the Ministry of Finance to establish a arrangements for implementing Norway's association with the EU ETS in the model MSG6. It also addresses the EU ETS policy instruments interacting with other objectives and instruments of climate policy, including the Kyoto commitments and various domestic Climate tax systems. The European emissions trading price affect the Norwegian economy through several channels. Firstly, allowances mean that the EU ETS will cover activities that gets an emission rate equal to the permit price, which will influence the players to reduce emissions through various adaptations. Second, the remaining emissions occur subject to quotas, and the proportion who do not receive free allowances will give the state the auction revenue / proceeds. Third, quotas purchased in international markets will affect account surplus. This paper outlines various solutions and concludes by recommending a system that easily can be adapted for studies of any interaction between the EU ETS system and other climate policy objectives. The system can also be easily updated to new data.(eb)

    To verify the clean coal technology to be diffused in China and consolidate its diffusion basis, demonstration project of circulating fluidized bed boiler was conducted through the cooperation with China which is positive in its introduction. This report describes its characteristics. Coal and limestone are supplied in a lower part of combustion chamber, and are mixed with circulating ash by fluidized air for combustion. Densely fluidized bed the same as the bubbling fluidized bed is formed in the lower part of combustion chamber, which provides excellent stability in ignition and combustion. Particles including ash, char and limestone formed during the combustion are discharged into the cyclone through the convection heat transfer part at the outlet of combustion chamber with the combustion gas flow. Since the gas temperature is lowered to 400 to 500degC at the convection heat transfer part, troubles of the ash circulating system can be prevented. The combustion gas separated from ash at the cyclone is discharged through the heat exchanger and precipitator, and the collected ash is returned to the lower part of combustion chamber. In FY 1997, design, fabrication, procurement/inspection, field survey/meeting, survey of visitors/meeting, and education were carried out. 4 figs., 4 tabs.

    A 1 T/D solvent-extraction type coal liquefaction test plant was constructed and operated to obtain the technical data for the design of, and establish the techniques for, an efficient coal liquefaction plant. The FY 1980 program includes surveys on the materials for coal liquefaction plants, covering those already developed and under development, to clarify the problematical points; drafting the test schedules; and conceptual designs of the material testing facilities. The major problems involved in the materials for coal liquefaction plants include erosion by fluidizing coal slurry, hydrogen embrittlement of the reactor materials, and corrosion by the liquefaction products (e.g., stress-corrosion cracking of austenitic steel, and corrosion by organic acids). The surveys on materials research trends suggest that USA seems to concentrate their research efforts on the reactor materials. The corrosion tests are mostly of in-plant tests, but the stress corrosion and slurry erosion tests are conducted on a laboratory scale. The conceptual designs are drawn for some testing units, e.g., the loop type material testing unit and basic testing unit for jet-spray type slurry erosion. (NEDO)

    The present study, as part of the studies on coal liquefying technologies, was originally intended to develop optimal catalysts that make it possible to manufacture a liquid fuel from hydrogenation treatment of coal, and establish optimal reaction operation for the liquefaction process. To achieve the intentions, studies were moved forward on the following four sub-themes: (1) fundamentals and developmental research on catalysts for the direct liquefaction, (2) chemical structures of organic constituents in the coal liquefaction process, (3) research on the optimal reaction operation in the direct coal liquefaction process, and (4) studies on nature and behavior of ash constituent in the coal liquefaction process. The current fiscal year has performed the discussions on the following items based on the achievements attained by fiscal 1987: 1. as a study on liquefaction catalysts, (1) a study on properties of liquefaction catalysts, and (2) a study on characteristics of the liquefying reaction; 2. as a study on the analytic method, (1) a study on the liquefying reaction analyzing method, and (2) a study on the liquefied oil property analyzing method. In Item 1-(1), a prototype zeolite-based catalyst having high hydrogenating decomposition activity was used to execute a reaction to lighten the liquefied oil. As a result, it was revealed that the liquefied oil can be lightened efficiently by having the oil go through a two-stage reforming reaction. (NEDO)

    The report deals with the use of coal and coke in Sweden during 1994. Some information about technology, environmental questions and markets are also given. Data have been collected by questionnaires to major users and by telephone to minor users. Preliminary statistical data from Statistics Sweden have also been used.The use of steam coal for heating purposes has been unchanged during 1994 at a level of 1 Mtons. The production in the cogeneration plants has been constant, but has increased for electricity production. The minor plants have increased their use of forest fuels. The use of steam coal will probably go down in the next years both for heat and cogeneration plants. During the top year 1987 coal was used in 18 hot water and 11 cogeneration plants. 1994 these figures are 3 and 12. Taxes and environmental reasons explain this trend. The use of steam coal in industry has been constant at the level 0.7 Mtons. The import of metallurgical coal in 1993 was 1.6 Mtons, like 1992. Import of 0.3 Mtons of coke gives the total consumption of coke in industry as 1.5 Mtons. the average price of steam coal imported to Sweden was 317 SEK/ton, 3% higher than 1993. All Swedish plants meet their emission limit of dust, SO 2 and NO x as given by county administrations or concession boards. The cogeneration plants all have some SO 2 removal system. The biggest cogeneration plant (Vaesteraas) has recently invested in a SCR NO x cleaning system. Most other plants use low NO x burners or SNR injection systems based on ammonia or urea. 2 figs, 13 tabs

    Full Text Available An analysis was made of comments in media reports on the selected case, the „Orzesze” mining project, posted by Internet users on news websites during the period July 2014 - December 2016 This article is an attempt to examine the relationship with the Other/Alien when thinking about conflicts around investment projects which will interfere with the surrounding social and natural environment. The article considers the theories on the sources of conflict and the development of the conflict process and its consequences and suggests possible courses of action to prevent the escalation of such conflicts particularly with respect to the “Orzesze” mining project in the Upper Silesia, Poland. Taking into account that the Data, Relationship, Value, and Interest conflicts can all be sources of conflict, it should be underlined that good social communication is extremely important in the prevention and resolution of conflicts and the mitigation of their destructive influence. In a cooperation/communication oriented environment it would be much easier to focus on finding solutions rather than finding the guilty party as this can lead to an escalation of the conflict as searching for the guilty party is inextricably linked with the desire to win or to take revenge.

    The Asian region is unique in the world in having the highest economic growth rate, the highest share of coal in total primary energy consumption and the highest growth rate in electricity generation capacity. The outlook for the next two decades is for accelerated efforts to control coal related emissions of particulates and SO 2 and to a lessor extent NO x and CO 2 . Only Japan has widespread use of Clean Coal Technologies (CCTs) however a number of economies have plans to install CCTs in future power plants. Only CCTs for electricity generation are discussed, and are defined for the purpose of this paper as technologies that substantially reduce SO 2 and/or NO x emissions from coal-fired power plants. The main theses of this paper are that major increases in coal consumption will occur over the 1990-2010 period, and this will be caccompanied by major increases in coal related pollution in some Asian economies. Coal fired electricity generation is projected to grow at a high rate of about 6.9 percent per year over the 1990-2010 period. CCTs are projected to account for about 150 GW of new coal-fired capacity over the 1990-2010 period of about one-third of all new coal-fired capacity. A speculative conclusion is that China will account for the largest share of CCT additions over the 1990-2010 period. Both the US and Japan have comparative advantages that might be combined through cooperation and joint ventures to gain a larger share of the evolving CCT market in Asia. 5 refs., 7 figs., 4 tabs

    The construction and operation of large-scale energy or resource development projects are accompanied by environmental, social, and economic changes or impacts. Impact assessment is the key tool used to determine which impact areas will most severely affect the community and will thus need to be managed. Impact management, only recently recognized as part of the assessment process, includes public and private actions to ameliorate impacts. The use of available impact management strategies can affect the outcome or change in the social and economic environment in a community. Therefore, an inventory of available strategies and the capabilities of local governments to use such strategies should be an integral part of any social and economic impact assessment. This provides a link between impact assessment and management. This report provides an introductory analysis to some of the more complex issues raised by social and economic impact management, with experiences cited from Western coal-development communities. Following an introduction, the paper is divided into sections corresponding to the major social and economic impacts experienced by rural communities surrounding an energy development. Each section contains a brief introductory description of the types of problems typically associated with the impact sector, and a discussion of management strategies either proposed or implemented for the impact. The management strategies are presented in tabular form, indicating the level of government responsible for implementation. 10 tables, 72 references. (MCW)

    The acid rain control legislation has prompted the Department of Energy (DOE) to seek new technology using the Clean Coal Technology program solicitation. The main goal of the program is to reduce SO 2 emissions below 9 Mt/a (10 million stpy) and NO x emission below 5.4 Mt/a (6 million stpy) by the year 2000. This would be accomplished by using precombustion, combustion, post combustion and conversion technology. Utilities are considering installing new scrubbers, switching fuel or possibly deep clean. However, the time required to implement the control technology is short. Due to the legislation, about 110 plants will have to adopt one of the approaches. This paper reports that in characterization of coal, Ames Laboratory used a scanning electron microscope- based, automated image analysis (SEM-AIA) technique to identify coal and mineral matter association. Various forms of organic sulfur were identified using peroxyacetic acid oxidation of coal. This was followed by subsequent microscopic, GC-MS, and HRMS analysis by Southern Illinois University. In ultrafine grinding of coal, it was reported by the Mining and Mineral Institute of Alabama that silica sand or flint shot used less energy compared to steel ball mills

    This final project report presents the activities and accomplishments of the ''Coal Combustion Products Extension Program'' conducted at The Ohio State University from August 1, 2000 to June 30, 2005 to advance the beneficial uses of coal combustion products (CCPs) in highway and construction, mine reclamation, agricultural, and manufacturing sectors. The objective of this technology transfer/research program at The Ohio State University was to promote the increased use of Ohio CCPs (fly ash, FGD material, bottom ash, and boiler slag) in applications that are technically sound, environmentally benign, and commercially competitive. The project objective was accomplished by housing the CCP Extension Program within The Ohio State University College of Engineering with support from the university Extension Service and The Ohio State University Research Foundation. Dr. Tarunjit S. Butalia, an internationally reputed CCP expert and registered professional engineer, was the program coordinator. The program coordinator acted as liaison among CCP stakeholders in the state, produced information sheets, provided expertise in the field to those who desired it, sponsored and co-sponsored seminars, meetings, and speaking at these events, and generally worked to promote knowledge about the productive and proper application of CCPs as useful raw materials. The major accomplishments of the program were: (1) Increase in FGD material utilization rate from 8% in 1997 to more than 20% in 2005, and an increase in overall CCP utilization rate of 21% in 1997 to just under 30% in 2005 for the State of Ohio. (2) Recognition as a ''voice of trust'' among Ohio and national CCP stakeholders (particularly regulatory agencies). (3) Establishment of a national and international reputation, especially for the use of FGD materials and fly ash in construction applications. It is recommended that to increase Ohio's CCP utilization rate from 30% in 2005 to

    The paper attempts to assess the impact of variability of selected geological (deposit) parameters on the value and risks of projects in the hard coal mining industry. The study was based on simulated discounted cash flow analysis, while the results were verified for three existing bituminous coal seams. The Monte Carlo simulation was based on nonparametric bootstrap method, while correlations between individual deposit parameters were replicated with use of an empirical copula. The calculations take into account the uncertainty towards the parameters of empirical distributions of the deposit variables. The Net Present Value (NPV) and the Internal Rate of Return (IRR) were selected as the main measures of value and risk, respectively. The impact of volatility and correlation of deposit parameters were analyzed in two aspects, by identifying the overall effect of the correlated variability of the parameters and the indywidual impact of the correlation on the NPV and IRR. For this purpose, a differential approach, allowing determining the value of the possible errors in calculation of these measures in numerical terms, has been used. Based on the study it can be concluded that the mean value of the overall effect of the variability does not exceed 11.8% of NPV and 2.4 percentage points of IRR. Neglecting the correlations results in overestimating the NPV and the IRR by up to 4.4%, and 0.4 percentage point respectively. It should be noted, however, that the differences in NPV and IRR values can vary significantly, while their interpretation depends on the likelihood of implementation. Generalizing the obtained results, based on the average values, the maximum value of the risk premium in the given calculation conditions of the "X" deposit, and the correspondingly large datasets (greater than 2500), should not be higher than 2.4 percentage points. The impact of the analyzed geological parameters on the NPV and IRR depends primarily on their co-existence, which can be

    The survey has given an eye to the coal that it can be easily burnt together with combustible waste and supplements unstable generation of waste. Thus, the establishment of the Energy Center at the place where infrastructure of coal will be arranged, a lot of combustible waste will be expected to generate and a considerable aniybt if energy will be used, has been planned, and this survey is intended to study the scale of Energy Center, its economy and the problems to be solved. In power plant project using RDF for above-mentioned local governments, the construction of power plant and the renewal time of the existing incinerator to RDF facility can be planned separately in this system. The power plant will be economically constructed and the amount of coal can be decreased in accordance with increased RDF to meet wide range of refuse treatment. In FY 1997, the actual situation of the waste treatment and the infrastructure of coal supply was surveyed, and selection of the place suitable for the Energy Center and its scale was studied. 69 figs., 50 tabs.

    In the destructive distillation of bituminous coal, heavy hydrocarbon oil, such as petroleum, kerosine, shale oil, and heavy tar oil, obtained in some cases during the process, is added to the coal, which is then distilled under pressure and at a comparatively low temperature regulated so as to produce a large proportion of hydrocarbon oils and a small proportion of permanent gas. In one method, about 5 to 10 parts of hydrocarbon oil are mixed with 100 parts of crushed or ground coal, and the mixture is heated in a closed vessel, provided in some cases with an agitator, under a pressure of about 60 lb/in/sup 2/, and the temperature may be gradually raised to 350/sup 0/C and then to about 500/sup 0/C.

    CoalVal is a menu-driven Windows program that produces cost-of-mining analyses of mine-modeled coal resources. Geological modeling of the coal beds and some degree of mine planning, from basic prefeasibility to advanced, must already have been performed before this program can be used. United States Geological Survey mine planning is done from a very basic, prefeasibility standpoint, but the accuracy of CoalVal's output is a reflection of the accuracy of the data entered, both for mine costs and mine planning. The mining cost analysis is done by using mine cost models designed for the commonly employed, surface and underground mining methods utilized in the United States. CoalVal requires a Microsoft Windows? 98 or Windows? XP operating system and a minimum of 1 gigabyte of random access memory to perform operations. It will not operate on Microsoft Vista?, Windows? 7, or Macintosh? operating systems. The program will summarize the evaluation of an unlimited number of coal seams, haulage zones, tax entities, or other area delineations for a given coal property, coalfield, or basin. When the reader opens the CoalVal publication from the USGS website, options are provided to download the CoalVal publication manual and the CoalVal Program. The CoalVal report is divided into five specific areas relevant to the development and use of the CoalVal program: 1. Introduction to CoalVal Assumptions and Concepts. 2.

    Development of a bituminous coal liquefaction technology (NEDOL method) can be judged appropriate as a national project in the comprehensive view with the 21st century just around the corner. It is a fact that this project has spent the national budget not in a small amount. There is no prospect of the technology to be put into practical use in Japan at the present time. The coal liquefaction technology is a technology required inevitably in the situation where shortage of crude oil supply may endanger the existence of a nation. Therefore, there is sufficient significance in having demonstrated the effectiveness of the NEDOL method which can be applied to a large number of coal types and expected of high liquefaction yield. The contents of the 'technological package' to be prepared are so demanded that its usefulness can be retained until the time of a demonstration plant design and operation will come in the future. It is also desired that the human resources and the testing devices will be kept ensured, and the technologies developed under this project will be maintained and expanded. The present technology has low necessity of immediately putting into practical use in Japan at the present time. However, the technology should be kept available for use at any time, and retained for use in an urgent situation. (NEDO)

    Minister of the Soviet coal industry evaluates social and economic development plan of the Soviet coal industry from 1981 to 1985. Planned coal production should increase to 770-800 Mt, exceeding coal production in 1980 by 53 to 83 Mt. Proportion of coal mined by surface methods will further increase. Investment program concentrates on: construction of the Kansk-Achinsk fuel and energy basin, construction of the South Yakut coal basin and further development of surface mines in the Ehkibastuz basin. Proportion of coal mined in the Kuzbass will increase to 45% of the total coal output. Construction of the Kansk-Achinsk basin has the highest priority among the investment projects. Investment projects (construction of new coal mines and modernization of existing mines) in major coal basins in 1981 are analyzed. Mining machines and equipment for underground and surface black and brown coal mining are evaluated. Plans for developing new mining systems are described (e.g. narrow web coal cutter with chainless haulage system for thin and medium coal seams with drive system with power ranging from 110 to 315 kW). The following types of machines are discussed: coal cutters, shearer loaders, heading machines, belt conveyors, loaders. Selected social problems associated with manpower shortages for underground mining and for coal mines operating under extreme climatic conditions are also discussed.

    This research was intended to find the desirable direction of technological development, by discussing the effects of coal gasification/liquefaction technologies from every angle, for the purpose coping with the social demand for steadily and continuously obtaining clean energy. This year, the examination was conducted not only on the energy conversion technologies of coal gasification/liquefaction, but also on the impact generating from the entire supply system of coal energy from coal mine development to mining, transportation, storage and conversion to secondary energy. For this purpose, while the outline was grasped of coal resources in the world as well as each technology for the mining, transportation, storage, electric power generation by gasification, and high calorie gasification, a case study was made on the assumption that electric power generation and high calorie gasification were conducted by importing 1,000 tons of coal from overseas, extracting the impact on the basis of this case study. In addition, examination was made on the position of coal energy in the energy supply of the future, with an impact investigated on condition that about 300 million tons were imported equivalent to roughly 16% of energy supply in the year 2000 or about.

    This paper describes the achievements at the Government Industrial Development Laboratory, Hokkaido in the Sunshine Project in fiscal 1990. Surveys were carried on different catalytic activities for co-liquefaction of various types of coals. The Ru system was found preferable in acquiring fatty family products of low boiling points. Reactions of co-liquefaction constituents do not progress independently, but have positive interaction. Adding Ru is effective in accelerating hydrogenation of condensed aromatic rings and hydrogenation of cleaving nucleus, but in view of the hydrogenating decomposition capability, the Mo-system may be better. In a liquefaction plant test, diesel oil was manufactured by reforming and improving the Yallourn coal light oil. However, the oxygen content was too high, aggravating the temperature distribution control in catalyst bed, and not having achieved the intended denitrification rate. Discussions were given on co-liquefaction of the depressurization residues of Cold Lake (CLVB[vacuum bottom])/Athabasca (ATVB) and Battle River coal. The CLCVB and ATVB were turned into lower molecules easily through hydrogenation treatment. The reaction characteristics reflected the characteristics of medium oil. Depolymerization of coal has progressed faster in ATVB. In the study on the engineering property values, discussions were given on behavior of solid particles in a bubble column, and gas hold-up of slurry. (NEDO)

    This paper describes the achievements in the Sunshine Project in fiscal 1990 on research of coal liquefying reaction. The research contributes to developing a coal liquefaction technology as one of the methods for manufacturing clean energy and chemical raw materials from coal. In the fundamental study on the liquefaction, primarily liquefied heavy constituents in different types of coals were divided into such constituents as HI, TI, and THFI to discuss the performance and coking behavior of each constituent as solvent. Furthermore, effects of hydrogenation treatment were also elucidated. Decomposing reaction was performed on different heavy products to discuss effects of the reaction conditions. In the liquefying reaction using petroleum-based heavy oil as solvent, different shale oils were used in experiments for comparison with the case of using tar sand bitumen. In the study of reforming the product, comparison was carried out on reactions in hydrogenation treatment and contact decomposition of medium to heavy fractions of liquefied oil. A separation experiment was made on hetero compounds by means of solvent extraction and pressure crystallization of liquefied oil naphtha and light oil fraction. Effects of additive were investigated in an engine test on the stabilized and balanced light oil fraction. Discussions were given on high level utilization of heat treated oil recovered from residues in liquefaction distillation. (NEDO)

Los Alamos National Laboratory in the U.S. thought of a concept of the technology to produce hydrogen from coal and recover CO2 at the same time for underground fixation, and is proceeding with the practical application. The process does not need oxygen, combustion, nor heating to be newly made. What is needed except coal is only water and lime, both of which can be recycled. The process, which discharges nothing into the air, is a closed cycle. The HyPr-RING process in Japan is a technology to decompose coal in high temperature (about 650 degrees C)/high pressure (100-200 atm) water for hydrogen formation, absorbing the formed CO2 by CaO, etc. Both of the processes have the problem, but it is necessary to make information exchanges since Japan and the U.S. devised the process at the same time.

    CONSOL R D is conducting a three-year program to characterize process and product streams from direct coal liquefaction process development projects. The program objectives are two-fold: (1) to obtain and provide appropriate samples of coal liquids for the evaluation of analytical methodology, and (2) to support ongoing DOE-sponsored coal liquefaction process development efforts. The two broad objectives have considerable overlap and together serve to provide a bridge between process development and analytical chemistry.

    The need to remove the bulk of ash contained in flue gas from coal-fired power plants coupled with increasingly strict environmental regulations in the USA result in increased generation of solid materials referred to as coal utilisation by-products, or CUBs. More than 40% of CUBs were sold or reused in the USA in 2004 compared to less than 25% in 1996. A goal of 50% utilization has been established for 2010. The American Coal Ash Association (ACCA) together with the US Department of Energy's Power Plant Improvement Initiative (PPPI) and Clean Coal Power Initiative (CCPI) sponsor a number of projects that promote CUB utilization. Several are mentioned in this report. Report sections are: Executive summary; Introduction; Where do CUBs come from?; Market analysis; DOE-sponsored CUB demonstrations; Examples of best-practice utilization of CUB materials; Factors limiting the use of CUBs; and Conclusions. 14 refs., 1 fig., 5 tabs., 14 photos.

    At the last moment Kosice managed to overcome the threat of a more than 30-percent heating price increase. The biggest local heat producer, Teplaren Kosice, is running out of coal supplies. The only alternative would be gas, which is far more expensive. The reason for this situation was a dispute of the heating plant with one of its suppliers, Kimex. Some days ago, the dispute was settled and the heating plant is now expecting the first wagon loads of coal to arrive. These are eagerly awaited, as its supplies will not last for more than a month. It all started with a public tender for a coal supplier. Teplaren Kosice (TEKO) announced the tender for the delivery of 120,000 tons of coal in June. Kimex, one of the traditional and biggest suppliers, was disqualified in the course of the tender. The winners of the tender were Slovenergo, Bratislava and S-Plus Trade, Vranov nad Toplou. TEKO signed contracts with them but a district court in Kosice prohibited the company from purchasing coal from these contractors. Kimex filed a complaint claiming that it was disqualified unlawfully. Based on this the court issued a preliminary ruling prohibiting the purchase of coal from the winners of the tender. The heating plant had to wait for the final verdict. The problem was then solved by the company's new Board of Directors, who were appointed in mid October who managed to sign new contracts with the two winners and Kimex. The new contracts cover the purchase of 150-thousand tons of coal, which is 30,000 more than in the original tender specification. Each company will supply one third. (authors)

    During the second half of the 1990's Coal Bed Methane (CBM) production increased dramatically nationwide to represent a significant new source of income and natural gas for many independent and established producers. Matching these soaring production rates during this period was a heightened public awareness of environmental concerns. These concerns left unexplained and under-addressed have created a significant growth in public involvement generating literally thousands of unfocused project comments for various regional NEPA efforts resulting in the delayed development of public and fee lands. The accelerating interest in CBM development coupled to the growth in public involvement has prompted the conceptualization of this project for the development of a CBM Primer. The Primer is designed to serve as a summary document, which introduces and encapsulates information pertinent to the development of Coal Bed Methane (CBM), including focused discussions of coal deposits, methane as a natural formed gas, split mineral estates, development techniques, operational issues, producing methods, applicable regulatory frameworks, land and resource management, mitigation measures, preparation of project plans, data availability, Indian Trust issues and relevant environmental technologies. An important aspect of gaining access to federal, state, tribal, or fee lands involves education of a broad array of stakeholders, including land and mineral owners, regulators, conservationists, tribal governments, special interest groups, and numerous others that could be impacted by the development of coal bed methane. Perhaps the most crucial aspect of successfully developing CBM resources is stakeholder education. Currently, an inconsistent picture of CBM exists. There is a significant lack of understanding on the parts of nearly all stakeholders, including industry, government, special interest groups, and land owners. It is envisioned the Primer would being used by a variety of

    China's energy supply is dominated by coal, making projections of future coal production in China important. Recent forecasts suggest that Chinese coal production may reach a peak in 2010–2039 but with widely differing peak production levels. The estimated URR (ultimately recoverable resources) influence these projections significantly, however, widely different URR-values were used due to poor understanding of the various Chinese coal classification schemes. To mitigate these shortcomings, a comprehensive investigation of this system and an analysis of the historical evaluation of resources and reporting issues are performed. A more plausible URR is derived, which indicates that many analysts underestimate volumes available for exploitation. Projections based on the updated URR using a modified curve-fitting model indicate that Chinese coal production could peak as early as 2024 at a maximum annual production of 4.1 Gt. By considering other potential constraints, it can be concluded that peak coal in China appears inevitable and immediate. This event can be expected to have significant impact on the Chinese economy, energy strategies and GHG (greenhouse gas) emissions reduction strategies. - Highlights: • Review of Chinese coal geology and resources/reserves. • Presentation of the Chinese coal classification system. • Forecasting future Chinese coal production using Hubbert curves. • Critical comparison with other forecasts. • Discussions transportation, environmental impact, water consumption, etc

    The coal sector in Kazakhstan is said to have enough reserves to last over 100 years, but the forecasted reserves are expected to last several hundreds of years. This makes investing in the fuel and energy sector of the country an attractive option for many international and private organisations. The proven on-shore reserves will ensure extraction for over 30 years for oil and 75 years for gas. The future development of the domestic oil sector depends mainly on developing the Kazakh sector of the Caspian Sea. The coal sector, while not a top priority for the Kazakh government, puts the country among the world's top ten coal-rich countries. Kazakhstan contains Central Asia's largest recoverable coal reserves. In future, the development of the raw materials base will be achieved through enriching and improving the quality of the coal and the deep processing of coal to obtain fluid fuel and synthetic substances. Developing shale is also topical. The high concentration of methane in coal layers makes it possible to extract it and utilise it on a large scale. However, today the country's energy sector, which was largely established in the Soviet times, has reached its potential. Kazakhstan has about 18 GW of installed electricity capacity, of which about 80% is coal fired, most of it built before 1990. Being alert to the impending problems, the government is planning to undertake large-scale modernisation of the existing facilities and construct new ones during 2015-30. The project to modernise the national electricity grid aims to upgrade the power substations to ensure energy efficiency and security of operation. The project will result in installation of modern high-voltage equipment, automation and relay protection facilities, a dispatch control system, monitoring and data processing and energy management systems, automated electricity metering system, as well as a digital corporate telecommunication network.

    For the purpose of getting petroleum substitution energy and reducing greenhouse effect gas emission, an investigational study was carried out of the project for methane gas recovery/utilization at the Donbassa coal mine in Ukraine. At the Donbassa coal mine, degassing by test boring is being conducted to reduce the gas emission at coal face for safety, but most of the gas is discharged into the air. In this project, the following were studied: degassing boring/gas induction from bore hole/measurement in gas induction pipe, gas recovery system combined with gas induction in flyash, and installation/operation of gas engine power generation facilities (1,710kW x 7 units) with exhaust heat recovery boiler using the recovered methane gas as fuel. The results obtained were the petroleum substitution amount of 31,000 toe/y and the amount of greenhouse effect gas reduction of 480,000 t/y. In the economical estimation, the initial investment amount was 3 billion yen, the profitability of the total investment used was 2.9%, and the internal earning rate was 6.5%. (NEDO)

    Evaluation was given on improvement measures to enhance quality of coal in Shanxi Province in China (Datong coal), which is exported to Japan in a large quantity. Quality problems in the Datong coal are mixture of foreign materials and quality level variation. In spite of the demands from the Japanese side, no large progress has been made in the past decade. As a result of discussions, the following improvement measures were enumerated: review on works at blast boring facings, more thorough cleaning of freight cars at the mines, exhaustive separation and recovery of plus 50 mm in coal dressing, completely mechanized boring, dressing treatment on coals purchased from other mines, whole grain size dressing treatment, establishment of the sales system of one mine selling one kind of coal, use of dedicated freight cars for Datong coal for export in railway transportation, assurance of dedicated coal storage yards in embarking ports, and improvement in the blending system at embarking ports. Understanding on quality control by highest executives at the Datong Mining Bureau and managers of each mine has been considerably deepened through the present investigation having been done over two fiscal years. As a result, the quality control mechanism was structured, the whole grain size dressing is performed, simplified dressing facilities were newly installed, and magnet separators were installed additionally.

    Evaluation was given on coal production quantity and coal transportation capability in areas scheduled of future development in Karimantan, Indonesia. Discussions were given on an optimal coal transportation system in East Karimantan Province. The coal production quantity in East Karimantan in fiscal 1999 was 35.27 million tons, accounting for 48% of the total Indonesian coal production. Production of 81.90 million tons is anticipated in 2020. Quality of the coal being produced is low in ash and high in water content in general. Calorific power is 5800 kcal or more. Sulfur content is 0.5% or more, not necessarily a low sulfur coal. The result of analyzing the optimal transportation routes by using the LP model may be summarized as follows: such scenarios are regarded to be largely profitable and advantageous that assume making railways utilizable as the land transportation in addition to use of trucks, belt conveyers, and barges, expanding coal terminals at the ports of PBCT, KPC, BCT and NPLCT, and newly building ports at Tarakan, TgSengatta, BPCTH, and Mangkapadie.

    1979-10-01

    This paper examines statistics on world coal production and world coal reserves with figures from 1860 to 1974 provided in tables and graphs. Eighty percent of the total world coal reserves (92% of world brown coal reserves) lie in the USA and USSR. The recent increase in total coal reserve estimates is due to exploration in western USA and in the USSR east of the Urals. Depth and thickness of the world's coal seams are shown in graphs and variations in coal quality are discussed. Problems associated with the anticipated substantial increase in coal production up to the year 2000 are considered. Encouraging higher coal production is the successful development of highly mechanized underground mining techniques and highly productive heavy surface mining equipment which allows excavation at increased depths. Surface mining is expected to make up 50% of total world mining operations in the near future. More complete deposit exploitation also contributes to higher coal production. Low international ship freight rates would facilitate future world coal trade. Obstacles are seen as: high, long term investments due to the fact that coal reserves lie far from populated and industrialized areas; opening new mines; transportation costs and infrastructure development.

The following items are discussed based on the achievements obtained by fiscal 1985: in the studies on coal liquefying catalysts, (1) a study on selectively liquefying catalysts, in which elucidation is made on effects of catalyst carriers on reaction selectivity and life of coal liquefying catalysts, and fundamental data are accumulated toward designing the catalysts with respect to catalyst carriers capable of selective hydrogenating reactions, and to carrying conditions; and (2) a study on solvent properties and reaction conditions. in which Mo-based catalysts are used to perform kinetic discussions on the relationship between the liquefying reaction conditions and compositions of solvents and produced oil to accumulate data for elucidating the action mechanisms of the Mo-based catalysts. In the study of the liquefied oil analyzing method, discussions are carried out on a measuring technology to expand the conventional method for liquefied oil analysis to hard-to-volatilize components. For the light and medium oils, an analyzing method will be established that utilizes effectively the NMR method and the MS method that have been established to date. (NEDO)

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

    The present research project involved a study of the depolymerisation of brown coal constituents. The purpose of the depolymerisation experiments, which were carried out with fungi as well as their (acellular) enzymes, was to obtain products with a potential market value. Research focussed on one of the key enzymes of lignocellulose degradation, namely manganese (II) peroxidase (MnP). The effects of this enzyme on the depolymerisation of brown coal was studied in detail in acellular systems. The insights gained in this way then served as a basis for optimising the fungal and enzymatic depolymerisation processes for maximum yields of low-molecular products. The experiments carried out during the period under review were oriented to finding new types of lignolytically active organisms, isolating lignolytic enzymes and immobilising them on natural support materials, and further examining the action spectrum of MnP. Different model substrates were used in order to gain information on what bond types are MnP-cleavable and on possible reaction products. Substrates were either fixed to silica gel as support material or used without support material. The idea of using substrates fixed to support materials was motivated by the need to distinguish between intracellular and extracellular reactions involving the fungal mycelium.

    The project objective is to assess the degree of applicability of in-seam seismic technology in Spanish coal mines for use as a tool to predict the presence of irregularities in coal seams. By the very nature of coal mining, a large number of in-seam seismic research results are put directly to the test by the ensuing underground operations. The statistics from this continuous process of verification in other countries show this method to be extremely successful. Indeed, the use of the method has become habitual and it is recognised as an efficient instrument for aiding the location of faults and other irregularities in coal seams. 3 figs., 2 tabs.

    The article considers trade development in major dry bulk commodities, coal, cement, iron ore and grains. Aspects covered for coal are production and exports. All coal mines in Poland are state owned. Coal production has fallen from an annual output in excess of 190 mta in the late 1980s, to under 150 mt in 1990. Output for 1991 is forecast at around 142 mt. Exports have also declined from 36 mtce in the late 1980s to an estimated 20 mt in 1991. Various factors are cited for the changing fortunes of Poland's coal industry but the most significant is the introduction of market forces to a previously centrally planned economy. Topics discussed for coal include: restructuring the coal industry for privatisation; eliminating subsidies; and export destinations. 5 tabs., 6 photos.

    In 1994, a memorandum on the research cooperation was agreed between NEDO and BPPT (The Agency for the Assessment and Application Technology) in Indonesia, based on the request for the coal liquefaction technology cooperation from BPPT. It includes the following items: conference for professionals to be held, invitation and training of Indonesian engineers, activity for joint field survey and potential survey of location of coal liquefaction commercial plant. Further in 1997, the secondary memorandum was concluded for the potential survey for securing the hydrogen required for coal liquefaction by coal gasification. The survey was summarized as the potential survey for location of coal liquefaction. In the testing study for improving economical efficiency of liquefaction process, it was made clear that the higher the Fe content of Banko coal is, the higher the reaction of liquefaction is, and that Fe compounds in coal show catalysis. In the Soroako area in Sulawesi island, there are the nickel mine run by PT. Inco. Soroako limonite is promising as catalyst material for commercial-scale coal liquefaction. In the gasification method, the plant construction cost increases, but the production amount of coal-derived liquid can be increased. That is more profitable than the production of hydrogen from natural gas. (NEDO)

    The goal of this project was to acquire experimental data required to assess the feasibility of a Direct Coal power plant based upon an Electrochemical Looping (ECL) of Liquid Tin Anode Solid Oxide Fuel Cell (LTA-SOFC). The objective of Phase 1 was to experimentally characterize the interaction between the tin anode, coal fuel and cell component electrolyte, the fate of coal contaminants in a molten tin reactor (via chemistry) and their impact upon the YSZ electrolyte (via electrochemistry). The results of this work will provided the basis for further study in Phase 2. The objective of Phase 2 was to extend the study of coal impurities impact on fuel cell components other than electrolyte, more specifically to the anode current collector which is made of an electrically conducting ceramic jacket and broad based coal tin reduction. This work provided a basic proof-of-concept feasibility demonstration of the direct coal concept.

    To conduct studies on the combustion of coal water fuels (CWFs) an appropriate facility was designed and constructed. The main components were (1) a high-temperature isothermal laminar flow furnace that facilitates observation of combustion events in its interior. The design of this system and its characterization are described in Chapter 1. (2) Apparatus for slurry droplet/agglomerate particle generation and introduction in the furnace. These devices are described in Chapters 1 and 3 and other attached publications. (3) An electronic optical pyrometer whose design, construction theory of operation, calibration and performance are presented in Chapter 2. (4) A multitude of other accessories, such as particle fluidization devices, a suction thermometer, a velocimeter, high speed photographic equipment, calibration devices for the pyrometer, etc., are described throughout this report. Results on the combustion of CWF droplets and CWF agglomerates made from micronized coal are described in Chapter 3. In the same chapter the combustion of CWF containing dissolved calcium magnesium acetate (CMA) axe described. The combustion behavior of pre-dried CWF agglomerates of pulverized grain coal is contrasted to that of agglomerates of micronized coal in Chapter 4. In the same chapter the combustion of agglomerates of carbon black and diesel soot is discussed as well. The effect of CMA on the combustion of the above materials is also discussed. Finally, the sulfur capture capability of CMA impregnated micronized and pulverized bituminous coals is examined in Chapter 5.

A comparative process synthesis, modelling and thermal assessment was conducted for the production of Bio-synthetic natural gas (SNG and hydrogen from supercritical water refining of a lipid extracted algae feedstock integrated with onsite heat and power generation. The developed reactor models for product gas composition, yield and thermal demand were validated and showed conformity with reported experimental results, and the balance of plant units were designed based on established technologies or state-of-the-art pilot operations. The poly-generative cases illustrated the thermo-chemical constraints and design trade-offs presented by key process parameters such as plant organic throughput, supercritical water refining temperature, nature of desirable coproducts, downstream indirect production and heat recovery scenarios. The evaluated cases favoring hydrogen production at 5 wt. % solid content and 600 °C conversion temperature allowed higher gross syngas and CHP production. However, mainly due to the higher utility demands the net syngas production remained lower compared to the cases favoring BioSNG production. The latter case, at 450 °C reactor temperature, 18 wt. % solid content and presence of downstream indirect production recorded 66.5%, 66.2% and 57.2% energetic, fuel-equivalent and exergetic efficiencies respectively.

It undertook a series...... of simulations examining regional integration and intra-African trade barrier reductions. The results for tariff elimination on intra-African trade are promising. But the real news is in confirming that these barriers are not as significant as the various trade-related barriers except for tariffs. Especially...... impressive results were forecast by simulating a modest 20% reduction in the costs associated with the particular African problem of transit time delays at customs, terminals and internal land transportation. These gains are significantly above both just intraAfrican tariff elimination and what may...

    ENGLISH ABSTRACT:The trade-off between time, cost, and quality is one of the important problems of project management. This problem assumes that all project activities can be executed in different modes of cost, time, and quality. Thus a manager should select each activity’s mode such that the project can meet the deadline with the minimum possible cost and the maximum achievable quality. As the problem is NP-hard and the objectives are in conflict with each other, a multi-objective meta-heuristic called CellDE, which is a hybrid cellular genetic algorithm, is implemented as the optimisation method. The proposed algorithm provides project managers with a set of non-dominated or Pareto-optimal solutions, and enables them to choose the best one according to their preferences. A set of problems of different sizes is generated and solved using the proposed algorithm. Three metrics are employed for evaluating the performance of the algorithm, appraising the diversity and convergence of the achieved Pareto fronts. Finally a comparison is made between CellDE and another meta-heuristic available in the literature. The results show the superiority of CellDE.

    This report deals with use of coal and coke during 1993; information about techniques, environmental questions and markets are also given. Use of steamcoal for heating purposes has been reduced about 3 % during 1993 to 1,0 mill tons. This is the case especially for the heat generating boilers. Production in co-generation plants has been constant and has increased for electricity production. Minor plants have increased their use of forest fuels, LPG and NG. Use of steamcoal will probably go down in the immediate years both in heat generating and co-generating plants. Coal-based electricity has been imported from Denmark during 1993 corresponding to about 400 000 tons of coal, when several of our nuclear plants were stopped. Use of steamcoal in the industry has been constant at 700 000 tons. This level is supposed to be constant or to vary with business cycles. The import of metallurgical coal in 1993 was 1,6 mill tons like the year before. 1,2 mill tons coke were produced. Coke consumption in industry was 1,4 mill tons. 0,2 mill tons of coke were imported. Average price of steamcoal imported to Sweden in 1993 was 308 SEK/ton or 13 % higher than in 1992; this can be explained by the dollar price level increasing 34% in 1993. For the world, the average import price was 50,0 USD/ton, a decrease of 6 %. The coal market during 1993 was affected by less consumption in Europe, shut downs of European mines and decreasing prices. High freight price raises in Russia has affected the Russian export and the market in northern Europe. The prices have been stabilized recently. All Swedish plants meet emission limits of dust, SO 2 and NO x . Co-generation plants all have some sort of SO 2 -removal system; the wet-dry method is mostly used. A positive effect of the recently introduced NO x -duties is a 40% reduction

    At the coalfield of Wuda (Inner Mongolia, PR China) extensive underground coal fires cause widespread thermal and oxidative effects in coal seams. Within phase B of the Coal Fire Research Project of the Sino-German Initiative, methods for innovative fire-extinguishing technologies were investigated in multifaceted research approaches. Extensive investigations of oxidative and thermally affected coal seams in coal fire zone 18 were conducted in 2008 prior to application of new fire-extinguishing methods. We present results from the outcrop of coal seam No. 4 in the fire zone 18. The coal of seam No. 4 is of Early Permian age and belongs stratigraphically to the Shanxi Formation. The unaffected coal displays a high volatile bituminous A rank with a background value of random vitrinite reflectance ranging from 0.90 to 0.96 % Rr. Coal channel samples were coallected at actively extracted coal faces along multiple profiles with surface temperatures ranging from about 50° to 600°C. Microscopic examinations revealed a variety of products of coal exposure to the fire. Within coal samples, a marked rise in vitrinite reflectance from background values to 5.55% Rr (6.00 % Rmax) is encountered. In addition, a number of coal samples showed suppressed vitrinite reflectances ranging between 0.82 to 0.88% Rr. Further, seemingly heat unaffected coal samples display intensive development of oxidations rims at coal grain edges and cracks as well as shrinkage cracks and formation of iron oxides/hydroxides. Instead, thermally affected coal samples with higher coalification grade are further characterised by development of macropores (devolatilisation pores) in vitrinitic streaks, transformation of liptinite to meta-liptinite and micrinite as well as by natural coke particles of mostly porous nature and fine to coarse grained anisotropic mosaic. Coal petrographic investigations confirmed a hypothesis that both, oxidations as well as low temperature carbonisation govern the thermal

    Japan-China joint coal survey was made through seismic prospecting by Japanese group and drilling prospecting by Chinese group. Mei-Xian mine property includes coal seams of the Jurassic period, and is covered with the quaternary period stratum without any coal seam. The base of the quaternary period stratum exists at depth of 50-400m, while the coal seams at depth of 300-700m. Among 11 existing seams, the 1st and 5th seams are main objects for prospecting. The 5th seam of 0.2-8.96m (2.95m in average) thick is the most expected important one, distributing all over the mine property. The 5th seam also has branch seams spreading over 2.5km from east to west and 1.2km from south to north in the center part of the mine property. The 1st seam of 0-8.62m (2.90m in average) thick is most thick in the south part of the mine property. The theoretical amount of coal deposits in the whole coal seam is estimated to be nearly 290,000,000t by Chinese group (nearly 50% of it in the 5th seam). That is also estimated to be nearly 346,000,000t by Japanese group (155,000,000t in the 5th seam). Both 1st and 5th seams are composed of sub-bituminous coal. (NEDO)

    Coal mining is one of Australia's most important industries. It was estimated that coal washery rejects from black coal mining was approximately 1.82 billion tonnes from 1960 to 2009 in Australia, and is projected to produce another one billion tonnes by 2018 at the current production rate. To ensure sustainability of the Australian coal industry, we have explored a new potential pathway to create value from the coal waste through production of liquid fuels or power generation using produced syngas from waste coal gasification. Consequently, environmental and community impacts of the solid waste could be minimized. However, the development of an effective waste coal gasification process is a key to the new pathway. An Australian mine site with a large reserve of waste coal was selected for the study, where raw waste coal samples including coarse rejects and tailings were collected. After investigating the initial raw waste coal samples, float/sink testing was conducted to achieve a desired ash target for laboratory-scale steam gasification testing and performance evaluation. The preliminary gasification test results show that carbon conversions of waste coal gradually increase as the reaction proceeds, which indicates that waste coal can be gasified by a steam gasification process. However, the carbon conversion rates are relatively low, only reaching to 20-30%. Furthermore, the reactivity of waste coal samples with a variety of ash contents under N{sub 2}/air atmosphere have been studied by a home-made thermogravimetric analysis (TGA) apparatus that can make the sample reach the reaction temperature instantly.

    This report discusses the geologic framework and petroleum geology used to assess undiscovered petroleum resources in the Bohaiwan basin province for the 2000 World Energy Assessment Project of the U.S. Geological Survey. The Bohaiwan basin in northeastern China is the largest petroleum-producing region in China. Two total petroleum systems have been identified in the basin. The first, the Shahejie&ndashShahejie/Guantao/Wumishan Total Petroleum System, involves oil and gas generated from mature pods of lacustrine source rock that are associated with six major rift-controlled subbasins. Two assessment units are defined in this total petroleum system: (1) a Tertiary lacustrine assessment unit consisting of sandstone reservoirs interbedded with lacustrine shale source rocks, and (2) a pre-Tertiary buried hills assessment unit consisting of carbonate reservoirs that are overlain unconformably by Tertiary lacustrine shale source rocks. The second total petroleum system identified in the Bohaiwan basin is the Carboniferous/Permian Coal–Paleozoic Total Petroleum System, a hypothetical total petroleum system involving natural gas generated from multiple pods of thermally mature coal beds. Low-permeability Permian sandstones and possibly Carboniferous coal beds are the reservoir rocks. Most of the natural gas is inferred to be trapped in continuous accumulations near the center of the subbasins. This total petroleum system is largely unexplored and has good potential for undiscovered gas accumulations. One assessment unit, coal-sourced gas, is defined in this total petroleum system.

    Surveys are carried out on the current status of information control systems for development projects being performed or planned in developing coal liquefaction technologies. The conception for structuring a coal liquefaction database (CLDB) is made clear to manage comprehensively and utilize effectively the information in the systems. Section 3 investigated and analyzed the current status of data processing for experimental plants. The data for each experimental plant are processed individually. Therefore, it is preferable that the CLDB shall be provided with accommodating locations to receive respective data. Section 4 put into order the flows of operation and information in the coal liquefaction research, and depicted an overall configuration diagram for the system. Section 5 discusses problems in structuring this system. There is a large number of problems to be discussed from now on, not only in the technological aspect, but in analyzing the organizational roles of NEDO and commissioned business entities, and the needs of users. The last section summarizes the steps and schedule for developing this system. The development steps should preferably be implemented stepwise along the progress of the experimental plants, in such an order as the fundamental database, analysis database and engineering database.

    agreement on a variety of methodological issues was reached on both sides of the Atlantic. Since 1993 the study has continued in Europe as the ExternE-Project, and now involves an international team of more than 30 organisations. The current study has 4 principal objectives; 1) To design a unified methodology for quantifying the various social costs associated with the production and consumption of energy. 2) To produce a framework to account for the external costs that result from incremental use of different fuels. 3) To use the methodology in an international comparative analysis. 4) To identify critical methodological issues and research requirements. At the same time as the publication of the present report, further reports are being published on the other major fuel cycles for electricity generation, including uranium, lignite, oil, gas, wind and biomass. In addition a further volume, providing greater detail on the methodology used for assessment of the fossil fuel cycles will also be published shortly. This document assesses the progress made in quantifying environmental and health damages associated with the coal fuel cycle. Estimates of impacts have been made following critical review of existing data and models rather than from original basic research. This review has been performed by a multi-disciplinary team including specialists in the fields of health, forestry, ecology, materials science, atmospheric chemistry and physics, energy technology, computer science and economics

    A study has been carried out into the feasibility of developing an electricity trading mechanism which would allow consumers to purchase electricity which has been derived from renewable energy resources. This study was part funded by the European Commission (ALTENER), the Department of Trade and Industry and a number of private sector companies. The trading mechanism is known as the Green Pool. As a result of the findings of this study discussions are being held with potential generators and suppliers to establish a Green Pool plc. The aim is to encourage the development of new renewable energy projects outside the NFFO and SRO schemes. The Green Pool plc will be owned by the generators and its main objective will be to market the electricity produced by its members. (Author)

  5. Energy strategy would slow coal's growth, says DOE

    1991-01-01

    The National Energy Strategy (NES) recently announced by the Bush Administration would slow the growth in use of coal by hundreds of millions of tons of coal by hundreds of millions of tons after 2000, according to the Department of Energy's (DOE) own figures. If today's policies are continued, coal consumption will nearly triple by 2030. Current annual consumption of more than 900 million tons (19 quadrillion Btus) would rise to 1,550 million tons in 2010 and to nearly 2,600 million tons by 2030. Coal's share of electricity generation, now about 55%, would grow to 75% by 2030 under the current policy base assumptions of the DOE. The NES, however, projects that surge of nuclear power plant construction will stem the growth of coal use. The strategy would still increase coal use, from 19 quadrillion Btus today to about 28 quads in 2010, but to only 32 quads by 2030. By 2030, coal would account for less than 50% of electricity generation under the NES. Total clean coal technologies capacity is substantially lower under the NES scenario case than under the clean coal actions alone. The strategy also contains good news for the coal industry in the short run. It holds out two main goals for coal policy: maintaining coal's competitiveness while meeting environmental, health and safety requirements; and creating a favorable export climate for US coal and coal technology

    The need for environmentally responsible electricity generation is a worldwide concern. Because coal is available throughout the world at a reasonable cost, current research is focusing on technologies that use coal with minimal environmental effects. The United States government is supporting research on clean coal technologies (CCTs) to be used for new capacity additions and for retrofits to existing capacity. To promote the worldwide adoption of US CCTs, the US Department of Energy, the US Agency for International Development, and the US Trade and Development Program sponsored a two-week seminar titled Clean Coal Technologies -- An International Seminar. Nineteen participants from seven countries were invited to this seminar, which was held at Argonne National Laboratory in June 1991. During the seminar, 11 US CCT vendors made presentations on their state-of-the-art and commercially available technologies. The presentations included technical, environmental, operational, and economic characteristics of CCTs. Information on financing and evaluating CCTs also was presented, and participants visited two CCT operating sites. The closing evaluation indicated that the seminar was a worthwhile experience for all participants and that it should be repeated. The participants said CCT could play a role in their existing and future electric capacity, but they agreed that more CCT demonstration projects were needed to confirm the reliability and performance of the technologies

    For the follow-up project, to promote the diffusion of results of the clean coal technology (CCT) model projects, experts of circulating fluidized bed boilers were dispatched, to guide and advise for the operation of facilities introduced in these projects. The purpose of these projects is to diffuse the CCTs, and to support the promotion of environmental measures. Some guidance and advice about operation processes, data processing, operation regulation, maintenance, and boiler maintenance works were provided to the Ministry of Energy and Electric Power Corporation of the Philippines. Semirara, Malangas, and Samar coals in the Philippines were used for the tests. The boiler facilities could be operated by Philippine operators themselves. Based on the guidance and advice about operation processes, combustion tests using various Philippine coals were also planned and conducted by themselves. The maintenance techniques were transferred to Philippine operators through the inspection, repair and advice. The Philippine side understood the technologies well, and the circulating fluidized bed boiler technology was independently educated in the Philippines. 23 figs., 16 tabs.

    For the purpose of the improvement of coal utilization technology and environmental preservation, the paper conducted the pre-survey of the introduction of coke oven gas desulfurization facilities in China and pre-survey of potentiality of the environmentally friendly type coal utilization system in India. The pre-survey in China was made for Anyang Steel Group Co. Ltd. and Laiwu Steel Group Co. Ltd. to judge their adaptability as site for the demonstrative project on the introduction of coke oven gas desulfurization facilities. As a result, it was confirmed that the former satisfied the conditions on Japan side such as the space for installation and prospect for fund raising. However, the amount of COG treatment was larger than that planned at Japan side, and it was found that as to the recovered sulfur, the company wanted the solid sulfur different from the fused sulfur planned at Japan side. In the survey in India, explanations were made to India of CFBC and the fluidized bed cement sintering system, bio-briquette production facilities, facilities for environmental measures, coal reforming technology, etc. At the same time, the site survey was made to examine/analyze possibilities of spread/development of Japan's CCT.

    This final report presents the research work carried out on the Coal Surface Control for Advanced Physical Fine Coal Cleaning Technologies project, sponsored by the US Department of Energy, Pittsburgh Energy Technology Center (DOE/PETC). The project was to support the engineering development of the selective agglomeration technology in order to reduce the sulfur content of US coals for controlling SO{sub 2} emissions (i.e., acid rain precursors). The overall effort was a part of the DOE/PETCs Acid Rain Control Initiative (ARCI). The overall objective of the project is to develop techniques for coal surface control prior to the advanced physical fine coal cleaning process of selective agglomeration in order to achieve 85% pyrite sulfur rejection at an energy recovery greater than 85% based on run-of-mine coal. The surface control is meant to encompass surface modification during grinding and laboratory beneficiation testing. The project includes the following tasks: Project planning; methods for analysis of samples; development of standard beneficiation test; grinding studies; modification of particle surface; and exploratory R&D and support. The coal samples used in this project include three base coals, Upper Freeport - Indiana County, PA, Pittsburgh NO. 8 - Belmont County, OH, and Illinois No. 6 - Randolph County, IL, and three additional coals, Upper Freeport - Grant County- WV, Kentucky No. 9 Hopkins County, KY, and Wyodak - Campbell County, WY. A total of 149 drums of coal were received.

    Chemical and petrographic analysis was conducted on coals from the Anadyrya and Bukhti Ugol'noi deposits. Characteristics of the most prevalent type of vitrinite coals in both regions are presented here. Anadyrya coals belong to a transitional phase between brown coal and long flame. Ultravitrinite coals predominate. Gas coals from Bukti Ugol'noi have a higher carbon content than Anadyrya coals. They also have a higher hydrogen content and yield of initial resin. In several cases there was also a higher yield of volatile substances. Chukotka coals are characterized by a 10 percent higher initial resin yield than equally coalified Donetsk coals, other indicators were equal to those of Donetsk coals. Because of this, Chukotka coals are suitable for fuel in power plants and as raw materials in the chemical industry. (15 refs.) (In Russian)

    2013-07-01

    Global consumption of commercial energy totalled 18 Gt of coal equivalent in 2010. With a 28% share, coal ranked second after oil as one of the major sources of primary energy and natural gas (at 21%) ranked third. Gross power generation with coal was approximately 41% and gas 22%. Natural gas as a global commodity is growing rapidly with the advent of unconventional sources such as shale gas. Recently, gas has become the fuel of choice for new power generating plants in some countries. Overall production of coal has increased in the same time-frame. The share of coal in electricity production was constant in Europe from early 2000 but recently increased. This was due to the high cost of gas in Europe and a low emissions penalty levied by the regulator, making coal currently more competitive in Europe compared to gas. Coal utilisation continues to increase in Asia but is facing serious competition with gas in the USA, where the share of electricity generated with coal dropped in 2012. However, natural gas used to generate electricity in early 2013 was below the high level seen during the comparable 2012 period, when low natural gas prices led to significant displacement of coal by natural gas for power generation. The current consensus in the USA is that while coal may recover ground in the short term, it loses in the long term as coal plants are retired. The discovery, production and availability of significant amounts of gas have implications for not only the price of natural gas but also the price of coal as well as supply and demand, and utilisation of both fuels internationally. The interaction between coal and gas in the global markets today is investigated in this review and the near-term outlook and impact on both fuels is presented. In this report, reserves, production and trade, supply and demand, pricing, utilisation and consumption, public attitudes and finally near/short to medium-term prospects are discussed for both coal and gas.

    2002-01-01

    The trading of greenhouse gas (GHG) emissions is being suggested as an effective economic way to meet Canada's Kyoto target. Emissions trading is a market-based instrument that can help achieve environmental improvements while using the market to absorb the economical and effective measures to achieve emissions reductions. Placing a value on emissions means that in order to minimize costs, companies will be motivated to apply the lowest-cost emission reductions possible for regulatory approval. The two main types of emissions trading that exist in Canada are the trading of emissions that lead to the formation of smog or acid rain, and the trading of greenhouse gas emissions that lead to climate change. Since carbon dioxide is the most prevalent GHG, making up approximately 75 per cent of Canadian GHG emissions, the trading of units of GHGs is often referred to as carbon trading. The impact that emissions trading will have on municipal operations was the focus of this primer. The trading of GHG involves buying and selling of allowances of GHGs between contracting parties, usually between one party that is short of GHG credits and another that has excess credits. The 3 common approaches to emissions trading include allowance trading (cap and trade), credit trading (baseline and credit), and a hybrid system which combines both credit and allowance trading systems. The issues that impact municipalities include the debate regarding who owns the credits from landfills, particularly if power is generated using landfill gas and the power is sold as green power. Other viable questions were also addressed, including who can claim emission reduction credits if a city implements energy efficiency projects, or fuel substitution programs. Also, will municipalities be allowed to trade internationally, for example, with municipalities in the United States, and how should they spend their money earned from selling credits. This report also presents highlights from 3 emissions

    Background Following a legal agreement with the European Union (EU), Philip Morris International (PMI) commissions a yearly report (‘Project Star’, PS) on the European illicit cigarette trade from KPMG, the global accountancy firm. Methods Review of PS 2010 report. Comparison with data from independent sources including a 2010 pan-European survey (N=18 056). Findings Within PS, data covering all 27 EU countries are entered into a model. While the model itself seems appropriate, concerns are identified with the methodologies underlying the data inputs and thus their quality: there is little transparency over methodologies; interview data underestimate legal non-domestic product partly by failing to account for legal cross-border sales; illicit cigarette estimates rely on tobacco industry empty pack surveys which may overestimate illicit; and there is an over-reliance on data supplied by PMI with inadequate external validation. Thus, PMI sales data are validated using PMI smoking prevalence estimates, yet PMI is unable to provide sales (shipment) data for the Greek islands and its prevalence estimates differ grossly from independent data. Consequently, comparisons with independent data suggest PS will tend to overestimate illicit cigarette levels particularly where cross-border shopping is frequent (Austria, Finland, France) and in Western compared with Eastern European countries. The model also provides data on the nature of the illicit cigarette market independent of seizure data suggesting that almost a quarter of the illicit cigarette market in 2010 comprised PMI's own brands compared with just 5% counterfeited PMI brands; a finding hidden in PMI's public representation of the data. Conclusions PS overestimates illicit cigarette levels in some European countries and suggests PMI's supply chain control is inadequate. Its publication serves the interests of PMI over those of the EU and its member states. PS requires greater transparency, external scrutiny and

    This paper examines whether some elements of Japan's resource acquisition strategies might have caused price and other distortions of market behaviour in the Pacific metallurgical coal trade. The industry chosen for investigation is that of steel manufacture, and the traded resources commodity examined is coking coal, which is the primary energy input for blast furnace iron making. Regression modelling studies to determine historic acquisition value and quality relationships for US, Australian and Canadian coals sold into the Japanese coking coal market are described. Departures from normal demand response behaviour to price competitiveness are also investigated. 3 figs., 3 tabs.

    The industrial capability and construction capability of Australia are surveyed in relation with the project of constructing a brown coal liquefaction plant there. Australian heavy industry is conspicuously advanced in the field of mining machinery involving coal, iron ore, and other mineral resources. On the other hand, in the fields of general-purpose machinery for plants and of civil engineering machinery, it is behind other countries in terms of technology and cost because of the small market. When an industrial project is implemented in Australia, consulting firms, engineering contractors, etc., operate independently from each other, and the project is propelled forward under a perfect specialization system. Labor-related problems in the civil engineering and construction industry are the recruitment of laborers which is difficult and the delay in and suspension of construction due to labor disputes that take place very frequently. In Victoria State where a brown coal liquefaction plant is under construction, the availability of laborers specializing in construction is rather higher than in other states, and there is no important problem in this respect. One cannot be too prudent in Victoria State, however, since it includes a region which is the most notorious in Australia in terms of labor-management dispute. (NEDO)

    This paper explains the results of research on direct liquefaction reaction of coal in fiscal 1981. The direct liquefaction is a reaction of three phases, gas-liquid-solid, under high temperature and high pressure. A tube type was employed in order to increase volume efficiency of the reactor, the continuous phase disperse number was decreased in order to bring it close to plug flow, and the paste Re number was increased to some extent in order to prevent sedimentation of coal particles. Hydrogen was supplied from the tube halfway for the purpose of supplementing the lowering of hydrogen partial pressure with the progress of reaction. A gas-liquid separator was installed so that increase in gas quantity was controlled in the rear stage of the reactor. As for catalysts, iron ore-sulfur system was examined which was promising as a disposable catalyst in place of the conventional iron system. Effect of catalytic addition was clearly recognizable in comparison with non-catalytic, with an exothermic peak observed comparable to the coal hydrogenation reaction of 350-420 degree C. Its catalytic effect was also presumable from the high pressure differential thermal analysis curve. The catalytic mechanism in the case where sulfur is added to hematite and limonite is similar to that of Fe{sub 2}O{sub 3} - sulfur catalyst, with the center of activity supposed to be Fe{sub 1-x}S. The catalytic effect is largely dependent on the particle size. (NEDO)

    The Department of Primary Industries and Energy is funding a joint research project between ABARE and the Energy Research Institute of China's State Planning Commission, China's leading organisation undertaking policy-related energy sector research. Together, the two organisations will analyse the economic costs and impacts of moving large quantities of coal from China's northern coal fields to, power stations in the rapidly growing south-eastern coastal provinces. The study will also compare the true economic costs of using domestic coal - including the costs of subsidies on coal production and transport - with the costs of using imported coal. ABARE will use its dynamic model, MEGABARE, to undertake ky parts of the study, taking into account the complex linkages between sectors in an economy and between different economies

  17. Coal lumps vs. electrons: How do Chinese bulk energy transport decisions affect the global steam coal market?

    This paper demonstrates the ways in which different Chinese bulk energy transport strategies affect the future steam coal market in China and in the rest of the world. An increase in Chinese demand for steam coal will lead to a growing need for additional domestic infrastructure as production hubs and demand centers are spatially separated, and domestic transport costs could influence the future Chinese steam coal supply mix. If domestic transport capacity is available only at elevated costs, Chinese power generators could turn to the global trade markets and further increase steam coal imports. Increased Chinese imports could then yield significant changes in steam coal market economics on a global scale. This effect is analyzed in China, where coal is mainly transported by railway, and in another setting where coal energy is transported as electricity. For this purpose, a spatial equilibrium model for the global steam coal market has been developed. One major finding is that if coal is converted into electricity early in the supply chain, worldwide marginal costs of supply are lower than if coal is transported via railway. Furthermore, China's dependence on international imports is significantly reduced in this context. Allocation of welfare changes particularly in favor of Chinese consumers while rents of international producers decrease.

    In recent decades, China has encountered serious environmental problem, especially severe air pollution that has affected eastern and northern China frequently. Because most air pollutants in China are closely related to coal combustion, the restriction of coal consumption is critical to the improvement of the environment in China. In this study, a panel of 29 Chinese provinces from 1995 to 2012 is utilized to predict China’s coal consumption through 2020. After controlling for the spatial correlation of coal consumption among neighboring provinces, an inverted U-shaped Environmental Kuznets Curve (EKC) between coal consumption per capita and GDP per capita in China is detected. Furthermore, based on the estimation results and reasonable predictions of key control variables, China’s provincial and national coal consumption through 2020 is forecasted. Specifically, under the benchmark scenario, consumption is expected to continue growing at a decreasing rate until 2020, when China’s coal consumption would be approximately 4.43 billion tons. However, if China can maintain relatively high growth rate (an annual growth rate of 7.8 percent), the turning point in total coal consumption would occur in 2019, with projected consumption peaking at 4.16 billion tons. - Highlights: • Provincial panel data is used to investigate the influential factors of coal consumption in China. • The spatial correlations of coal consumption in neighboring provinces are fully considered. • An inverted-U shaped Environmental Kuznets Curve for coal consumption in China has been found. • Based on the estimation results, China’s national coal consumption before 2020 is forecasted. • Under the basic scenario, China’s national coal consumption will grow at a decreasing speed till 2020.
