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.

The U.S. Department of Energy (DOE) was given a mandate in the 1992 Energy Policy Act (EPACT) to pursue strategies in coal technology that promote a more competitive economy, a cleaner environment, and increased energy security. Coal evaluates DOE's performance and recommends priorities in updating its coal program and responding to EPACT. This volume provides a picture of likely future coal use and associated technology requirements through the year 2040. Based on near-, mid-, and long-term scenarios, the committee presents a framework for DOE to use in identifying R&D strategies and in making detailed assessments of specific programs. Coal offers an overview of coal-related programs and recent budget trends and explores principal issues in future U.S. and foreign coal use. The volume evaluates DOE Fossil Energy R&D programs in such key areas as electric power generation and conversion of coal to clean fuels. Coal will be important to energy policymakers, executives in the power industry and related trade associations, environmental organizations, and researchers.

Mark Twain observed, “I'm in favour of progress; it's change I don't like.” Coal dominates Indian energy because it’s available domestically and cheap (especially without a carbon tax). If the global focus is on the energy transition, how does India ensure a just transition? Managing winners and losers will be the single largest challenge for India’s energy policy. Coal is entrenched in a complex ecosystem. In some states, it’s amongst the largest contributors to state budgets. The Indian Railways, India’s largest civilian employer, is afloat because it overcharges coal to offset under-recovery from passengers. Coal India Limited, the public sector miner that produces 85% of domestic coal, is the world’s largest coal miner. But despite enormous reserves, India imports about a quarter of consumption. On the flip side, coal faces inevitable pressure from renewable energy, which is the cheapest option for new builds. However, there is significant coal-based power capacity already in place, some of which is underutilized, or even stranded. Low per-capita energy consumption means India must still grow its energy supply. Before India can phase out coal, it must first achieve a plateau of coal. How this happens cost-effectively and with least resistance isn’t just a technical or economic question, it depends on the political economy of coal and its alternatives. Some stakeholders want to kill coal. A wiser option may be to first clean it up, instead of wishing it away. Across 18 chapters, drawing from leading experts in the field, we examine all aspects of coal’s future in India. We find no easy answers, but attempt to combine the big picture with details, bringing them together to offer a range of policy options.
This book presents the state of art of the several advanced approaches to beneficiation of coal. The influence of recent technology attains the advantages of processing coal, purification studies, rheological behavior, and the mineral beneficiation. The experts collected in this volume have contributed significantly to the enrichment in the in depth knowledge not only in context of working knowledge, but also future prospects of clean coal technology.
From 1868–1872, German geologist Ferdinand von Richthofen went on an expedition to China. His reports on what he found there would transform Western interest in China from the land of porcelain and tea to a repository of immense coal reserves. By the 1890s, European and American powers and the Qing state and local elites battled for control over the rights to these valuable mineral deposits. As coal went from a useful commodity to the essential fuel of industrialization, this vast natural resource would prove integral to the struggle for political control of China. Geology served both as the handmaiden to European imperialism and the rallying point of Chinese resistance to Western encroachment. In the late nineteenth century both foreign powers and the Chinese viewed control over mineral resources as the key to modernization and industrialization. When the first China Geological Survey began work in the 1910s, conceptions of natural resources had already shifted, and the Qing state expanded its control over mining rights, setting the precedent for the subsequent Republican and People's Republic of China regimes. In Empires of Coal, Shellen Xiao Wu argues that the changes specific to the late Qing were part of global trends in the nineteenth century, when the rise of science and industrialization destabilized global systems and caused widespread unrest and the toppling of ruling regimes around the world.
This book provides insights into the development and usage of coal in chemical engineering. The reactivity of coal in processes such as pyrolysis, gasification, liquefaction, combustion and swelling is related to its structural properties. Using experimental findings and theoretical analysis, the book comprehensively answers three crucial issues that are fundamental to the optimization of coal chemical conversions: What is the structure of coal? How does the underlying structure determine the reactivity of different types of coal? How does the structure of coal alter during coal conversion? This book will be of interest to both individual readers and institutions involved in teaching and research into chemical engineering and energy conversion technologies. It is aimed at advanced- level undergraduate students. The text is suitable for readers with a basic knowledge of chemistry, such as first-year undergraduate general science students. Higher-level students with an in-depth understanding of the chemistry of coal will also benefit from the book. It will provide a useful reference resource for students and university-level teachers, as well as practicing engineers.
