"Clean coal" technology is never going to work because every ton of coal burned emits 3.7 tons of CO2. The costs of disposing of that much CO2 is staggering. If we spent those development dollars on EGS geothermal power instead we could have a solution today. Geothermal plants use free energy in the earth to produce power without any pollution. Coal is carbon that was sequestered eons ago. Why dig it up, burn it to boil water and then try to rebury it when you have all the heat you need to boil water in the earth for free? Futuregen is a mistaken attempt to keep the coal business alive at great public expense. http://www.renewableenergyworld.com/rea/news/reinsider/story?id=51409
