Record-high world oil prices have prompted renewed interest in producing liquid fuels from coal. The United States leads the world in recoverable coal reserves. Moreover, the technology for converting coal to liquid fuels already exists, and production costs appear competitive at world oil prices well below current levels. Yet, despite its promise, private investment in coal-to-liquids (CTL) technology is being impeded by three uncertainties: where oil prices are heading, what it actually costs to produce coal-derived fuels, and how greenhouse-gas emissions will be regulated. A domestic CTL industry could produce as much as three million barrels per day of transportation fuels by 2030. Having such an industry would yield important energy security benefits, most notably a lowering of world oil prices and a decrease in wealth transfers from oil users to oil producers. But establishing a large CTL industry also raises important policy and environmental issues associated with climate change, coal mining, and water consumption. Weighing both benefits and costs, it makes sense for the United States to pursue an insurance or hedge strategy that promotes the early construction and operation of a limited number of commercial CTL plants. This book presents an in-depth review of the prospects of and policy, governance, and environmental issues associated with establishing a CTL industry in the United States. -- provided by publisher.
The transportation sector cannot continue on its current path: The volatility of oil prices threatens the U.S. economy, the large proportion of oil importation threatens U.S. energy security, and the massive contribution of greenhouse gases threatens the environment. The development of domestic sources of alternative transportation fuels with lower greenhouse emissions is now a national imperative. Coal and biomass are in abundant supply in the United States and can be converted to liquid fuels that can be combusted in existing and future vehicles. Their abundant supply makes them attractive candidates to provide non-oil-based liquid fuels to the U.S. transportation system. However, there are important questions about the economic viability, carbon impact, and technology status of these options. Liquid Transportation Fuels from Coal and Biomass provides a snapshot of the potential costs of liquid fuels from biomass by biochemical conversion and from biomass and coal by thermochemical conversion. Policy makers, investors, leaders in industry, the transportation sector, and others with a concern for the environment, economy, and energy security will look to this book as a roadmap to independence from foreign oil. With immediate action and sustained effort, alternative liquid fuels can be available in the 2020 time frame, if or when the nation needs them.
The United States Government Printing Office (GPO) was created in June 1860, and is an agency of the U.S. federal government based in Washington D.C. The office prints documents produced by and for the federal government, including Congress, the Supreme Court, the Executive Office of the President and other executive departments, and independent agencies. A hearing is a meeting of the Senate, House, joint or certain Government committee that is open to the public so that they can listen in on the opinions of the legislation. Hearings can also be held to explore certain topics or a current issue. It typically takes between two months up to two years to be published. This is one of those hearings.
In response to new environmental pressures on coal utilization, this report examines the benefits of coal-liquid fuels as an alternative and environmentally more benign fuel source. The evaluation is based on a detailed assessment of the impact of coal-liquid fuels on the various stages of a coal energy utilization cycle and a review of coal production technologies and their applications. The report also includes a crude assessment of costs and savings in the production, transportation, and utilization of coal-liquid fuels.
Government actions to gain early experience in producing liquid fuels from coal offer major energy security benefits but also raise important economic governance, and environmental issues.
This book deals with two inconsistent myths that persistently surround industrial use of coal. The first myth is that the Clean Air Act precluded the use of coal; the second, that industrial use of coal will expand rapidly as a result of purely economic choices. Through analyzing fuel-use decisions actually made by industry, Mr. Alm concludes that environmental quality standards have played a minor role in industrial choice of fuel. Historically, natural gas and oil have been both less costly and more convenient fuels for industry to use. Coal gained a substantial economic advantage over oil after the oil price increases of the last decade, yet it continues to maintain a lower market share than economics alone would suggest. Mr. Alm demonstrates that coal's share of the fuel market will continue to remain low because of the way U.S. businesses view fuel-use choices. For most U.S. firms, energy costs are a relatively small portion of total costs and a minor factor in a firm's ability to compete. Faced with alternative capital projects to expand production facilities or to make mandatory investments, companies do not generally give high priority to coal conversion projects. Moreover, most U.S. firms have little experience with burning coal, and that lack of expertise creates additional psychological and institutional barriers to coal's use. Finally, there is a tendency to prefer high-payoff, short-term investments over projects that promise cost savings many years in the future. These are all strong reasons for coal's lackluster performance in the industrial market—much more potent forces than environmental regulations.
Coproduction of power, fuels & chemicals offers an innovative, economically advantageous means of achieving the nation¿s energy goals. Coproduction involves the integration of 3 major building blocks: Gasification of coal or other hydrocarbon fuels to produce synthesis gas (syngas); Conversion of a portion of the syngas to high-value products such as liquid fuels & chemicals; & Combustion of syngas to produce electric power. Contents: Description of Gasification & Power Generation Technology; Syngas Conversion Processes; Industrial Applications of Gasification; Market Potential for Coproduction; Early Entrance Coproduction Plants; Conclusions; Bibliography; Contacts for CCT Projects & U.S. DOE CCT Program.
