Integrated gasification combined cycle (IGCC) electric power plants seem to becoming accepted as state of the art technology with the announcement that plants totaling 1,200 megawatts of capacity would be built. IGCC plants convert coal into gas that is burned in turbines to power electric generators. The process can significantly decreases emissions of nitrogen oxide, sulfur dioxide, particulates and mercury to well below that required by environmental regulations. The process reduces CO2 emissions by about 20%, but can isolate the CO2 into a separate stream if a means for disposal were available. Sequestration technologies have not been demonstrated on a large scale. The 2005 energy bill included funding for the Future Gen plant which incorporates sequestration technology.
According to a 9/16/05 article in the Charleston Daily Mail an executive from Appalachian Power Company, a subsidiary of American Electric Power, said that he is convinced that a $1 billion, 1,200 MW IGCC plant will be constructed in West Virginia.
