A Bid to Cut Emissions Looks Away From Coal

from the New York Times (Registration Required)

WASHINGTON -- As Congress debates legislation to slow global warming by limiting emissions, engineers are tinkering with ways to capture and store carbon dioxide, the leading heat-trapping gas.

But coal-fired power plants, commonly identified as the nation's biggest emissions villain, may not be the best focus.

Rather, engineers and policymakers say, it may be easier and less costly to capture the carbon dioxide at oil refineries, chemical plants, cement factories and ethanol plants, which emit a far purer stream of it than a coal smokestack does.
