The intent of this study is to investigate the feasibility of siting a lignite conversion plant in Texas at the mine mouth of the Wilcox lignite deposit. The concept is to coproduce at least three products: electric power, hydrogen or substitute natural gas (SNG), and carbon dioxide. The electric power would be sold to the grid, the hydrogen would be sent by pipeline to the Gulf Coast petroleum refineries, the SNG would be sold as a natural gas supplement, and the carbon dioxide would be pipelined to the West Texas oil fields for enhanced oil recovery.
