Study: US Technology Key To China And Climate

Together, the U.S. and China account for 20 percent of the world's carbon dioxide from coal burning power plants, said Moniz. If China doesn't address emissions from its coal plants "we really can't address the climate issue in a serious way."

The MIT report summarizes a consensus view of participants in a symposium sponsored by MIT's Energy Initiative on the feasibility of retrofitting existing coal plants with carbon capture technology. Participants included 54 representatives utilities, academia, government, public interest groups and industry.

The report said about half of the U.S. coal plants — most of those producing 300 megawatts or more of power — may be suitable for carbon capture technology. Many of the smaller plants, accounting for about 30 percent of electricity production, can achieve emission reductions through increased efficiency, use of a mix of coal and biomass as fuel and other measures. Other plants, especially the oldest, may have to be replaced, said Moniz.

Wayne Leonard, chief executive of Entergy Corp., who was a co-chairman of the symposium, said the symposium's conclusions should be viewed "in an international context" especially as carbon capture technology development relates to China.

"In the U.S. coal is the reality. But in China and India it is the future" and they won't abandon it because of climate change, said Leonard. "But offering them a technological solution, a solution that we are actively developing and deploying ourselves on our own coal plants, would be something that has a far better chance of success in getting them to act."
