The availability of clean, affordable energy is essential for the prosperity and security of the United States and the world in the 21st century. Carbon dioxide (CO{sub 2}) emissions to the atmosphere are an inherent part of energy-related activities, such as electricity generation, transportation, and building systems. These energy-related activities are responsible for roughly 85% of the U.S. greenhouse gas emissions, and 95% of these emissions are dominated by CO{sub 2}. Over the last few decades, an increased concentration of CO{sub 2} in the earth's atmosphere has been observed. Many scientists believe greenhouse gases, particularly CO{sub 2}, trap heat in the earth's atmosphere. Carbon sequestration technology offers an approach to redirect CO{sub 2} emissions into sinks (e.g., geologic formations, oceans, soils, and vegetation) and potentially stabilize future atmospheric CO{sub 2} levels. Coal seams are attractive CO{sub 2} sequestration sinks, due to their abundance and proximity to electricity-generation facilities. The recovery of marketable coal bed methane (CBM) provides a value-added stream, reducing the cost to sequester CO{sub 2} gas. Much research is needed to evaluate this technology in terms of CO{sub 2} storage capacity, sequestration stability, commercial feasibility and overall economics. CONSOL Energy, with support from the U.S. DOE, is conducting …
