The Department of Energy is asking the public to comment on the draft environmental impact statement for 22 clean coal technologies, from precombustion cleaning techniques to coal gasification and fuel cell systems. Incentives to promote use of these new methods for burning coal are included in President George Bush's proposed revisions to the Clean Air Act.
The draft is based on a computer model developed at Argonne National Laboratory, Illinois, and run at Oak Ridge National Laboratory, Tennessee. The model estimates the amounts of reduction by 2010 in national emissions of sulfur dioxide, nitrogen oxides and carbon dioxide that use of the new technologies could achieve. It also compares the amounts and kinds of solid waste produced by clean coal technologies to the solid waste of power-production technologies in use today.
