Large U.S. coal reserves and viable technology make promising a domestic industry producing liquid fuels from coal. Weighing benefits, costs, and environmental issues, a productive and robust U.S. strategy is to promote a limited amount of early commercial experience in coal-to-liquids production and to prepare the foundation for managing associated greenhouse-gas emissions, both in a way that reduces uncertainties and builds future capabilities.
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.
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.

Coal will continue to provide a major portion of energy requirements in the United States for at least the next several decades. It is imperative that accurate information describing the amount, location, and quality of the coal resources and reserves be available to fulfill energy needs. It is also important that the United States extract its coal resources efficiently, safely, and in an environmentally responsible manner. A renewed focus on federal support for coal-related research, coordinated across agencies and with the active participation of the states and industrial sector, is a critical element for each of these requirements. Coal focuses on the research and development needs and priorities in the areas of coal resource and reserve assessments, coal mining and processing, transportation of coal and coal products, and coal utilization.
As coal is considered as a substitute for other fuels, more serious attention is being given to the environmental impacts of the whole coal fuel cycle: mining, transport, storage, combustion and conversion. This volume presents an up-to-date account of these environmental impacts and the recent developments to combat and control them. A feature of the book is the way in which it discusses not only the experience and developments in North America and Western Europe but also presents much information made available for this study on the developments in the socialist countries of Eastern Europe.
This Special Issue of Energies on “Advances in Combustion of Gases, Liquid Fuels, Coal and Biomass” includes five manuscripts on combustion research related to energy production. Both fundamental and applied research is included. The papers contain state-of-the-art experiments, computations, and theory. Combustion provides an estimated 85% of the world’s energy consumption. Advances in combustion research can benefit society in three main ways. Improving energy efficiency can reduce fuel consumption. Improving emissions can reduce climate change and adverse health effects. Improving fire and explosion safety can protect people, property, and the environment. The topical areas covered by this Special Issue are broad. It is hoped that this breadth will lead to a better understanding of combustion and improved diagnostic and numerical tools. This, in turn, may result in improved combustors, a cleaner environment, novel fuels, and improved safety and energy security.
