Adieu carbon dioxide?

Wisconsin-based We Energies has teamed up with the Electric Power Research Institute and the French company Alstom to construct a system to capture carbon dioxide from coal-fired power plants. It will be the first plant in the nation to employ this technology, invented by Alstom, and is expected to start operating next year and be tested through 2008.

Chilled ammonia is used to capture the carbon dioxide before it's pumped into the atmosphere, and Alstom hopes to prove that the technology can prevent at least 90% of the carbon dioxide from being released into the atmosphere. Capturing carbon dioxide is increasingly vital to utilities as many CEOs expect the U.S. to limit or tax carbon dioxide emissions, the major contributor to global warming.
