Cleaner Energy from Coal is Closer to Reality

Coal-fired power plants have a new technology to produce "cleaner" energy. Called integrated gasification combined cycle (IGCC), this technology gasifies the coal before it's burned. At a cost of 20% more than traditional coal plants, harmful pollutants like particulates, small components, and mercury aren't sent into the atmosphere.

Environmentalists seem to agree that this is a good start, but would also like to see carbon dioxide trapped in the same process, to help prevent global warming. “Until coal is replaced with cleaner fuels, we must somehow make it part of the solution,” said Onearth editor Douglas Barasch.
