The Dirty Secret

Better technologies exist for extracting coal, a major source of carbon dioxide emissions. The challenge is getting people to adopt them.

Coal is the black sheep of the energy family. Uniquely abundant among the fossil fuels, it is also among the worst emitters of greenhouse gases. Mindful of coal's bad reputation, President Bush promised the world three and half years ago that the United States would develop a superclean coal plant in an initiative known as FutureGen. The plant would have zero emissions; even the carbon dioxide it released would be pumped underground.

Today there is a patch of land in Great Bend, OH, where an advanced coal plant may one day be built. The plant could eventually include equipment for siphoning off carbon dioxide. But it's not FutureGen, which today remains a collection of research projects. No FutureGen plant has been constructed, and no site for one has been chosen. The proposed plant at Great Bend could more appropriately be called "PresentGen." The technology involved doesn't demand a White House neologism suggesting that clean coal is something for which we must wait.
