Today's energy situation has created a dilemma for coal use in the United States. On one hand, the environmental challenges of using coal appear formidable, particularly with growing concern over the impact of carbon dioxide emissions on global climate change. On the other hand, the projected demand for electricity, coupled with high fuel costs, presents a near-term opportunity for the greater use of coal to ensure energy security for America. This solution to coal's "Catch-22" can be achieved through technological advancements that enable coal-based energy plants to produce much needed electricity and fuels for secure and stable economic growth. This book examines the development of the technological pathway of advanced power systems using bituminous coal.
