Coal mining continues to make advances, especially in the areas of safety and environmental protection as a result of mining. This book contains nine peer-reviewed articles on green coal mining that address most of the important issues associated with improving coal mining. These issues include the protection of water above coal mines, both surface and ground water, and the subsidence that occurs during and after mining with methods to limit it and methods of rehabilitation. Additional issues include mine entry and production area support and methods to control gas emissions.
The Office of Industrial Technologies (OIT) of the U. S. Department of Energy commissioned the National Research Council (NRC) to undertake a study on required technologies for the Mining Industries of the Future Program to complement information provided to the program by the National Mining Association. Subsequently, the National Institute for Occupational Safety and Health also became a sponsor of this study, and the Statement of Task was expanded to include health and safety. The overall objectives of this study are: (a) to review available information on the U.S. mining industry; (b) to identify critical research and development needs related to the exploration, mining, and processing of coal, minerals, and metals; and (c) to examine the federal contribution to research and development in mining processes.
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.
A forceful reckoning with the relationship between energy and power through the history of what was once East Asia’s largest coal mine. The coal-mining town of Fushun in China’s Northeast is home to a monstrous open pit. First excavated in the early twentieth century, this pit grew like a widening maw over the ensuing decades, as various Chinese and Japanese states endeavored to unearth Fushun’s purportedly “inexhaustible” carbon resources. Today, the depleted mine that remains is a wondrous and terrifying monument to fantasies of a fossil-fueled future and the technologies mobilized in attempts to turn those developmentalist dreams into reality. In Carbon Technocracy, Victor Seow uses the remarkable story of the Fushun colliery to chart how the fossil fuel economy emerged in tandem with the rise of the modern technocratic state. Taking coal as an essential feedstock of national wealth and power, Chinese and Japanese bureaucrats, engineers, and industrialists deployed new technologies like open-pit mining and hydraulic stowage in pursuit of intensive energy extraction. But as much as these mine operators idealized the might of fossil fuel–driven machines, their extractive efforts nevertheless relied heavily on the human labor that those devices were expected to displace. Under the carbon energy regime, countless workers here and elsewhere would be subjected to invasive techniques of labor control, ever-escalating output targets, and the dangers of an increasingly exploited earth. Although Fushun is no longer the coal capital it once was, the pattern of aggressive fossil-fueled development that led to its ascent endures. As we confront a planetary crisis precipitated by our extravagant consumption of carbon, it holds urgent lessons. This is a groundbreaking exploration of how the mutual production of energy and power came to define industrial modernity and the wider world that carbon made.

Readers will find a multidisciplinary approach elucidating all the important features of green hydrogen so that science researchers and energy engineers as well as those in economics, political science and international relations, will also find value. Energy sources and generation is the foremost concern of all governments, NGOs, and activist groups. With Green New Deals and reduced or net zero emission goals being implemented on a global scale, the quest for economic, scalable, efficient, and sustainable energy systems has reached a fever pitch. No one energy source ticks all the boxes and new energy technologies are being developed all the time as potential disruptors. Enter green hydrogen with zero emissions. Hydrogen is a rare gas in nature and is often found together with natural gas. While hydrogen is the most abundant element in the known universe, molecular hydrogen is very rare in nature and needs to be produced—and produced in large quantities, if we are serious about the Green Deal. This book has been organized into three parts to introduce and discuss these crucial topics. Part I discusses the Green Deal and the current state and challenges encountered in the industrialization of green hydrogen production, as well as related politics. Chapters in this section include how to decarbonize the energy industry with green hydrogen, and one that describes a gradual shift in the approach of hydrogen production technologies from non-renewable to renewable. Part II is devoted to carbon capturing and hydrogen. Chapters on biomass mass waste-to-hydrogen conversion and related efficient and sustainable hydrogen storage pathways, life cycle assessment for eco-design of biohydrogen factory by microalgae, and metal oxide-based carbon capture technologies are all addressed in this section. The third and final part of the book was designed to present all features of green hydrogen generation. Chapters include PEM water electrolysis and other electrolyzers, wind-driven hydrogen production, and bifunctional electrocatalysts-driven hybrid water splitting, are introduced and thoroughly discussed. Audience This book is directed to researchers and industry professionals in energy engineering, chemistry, physics, materials science, and chemical engineering, as well as energy policymakers, energy economists, and others in the social sciences.
