Optimizing Carbon Dioxide Removal from Coal-Fired Power Plants
In some of the first results from a federally funded initiative to find new ways of capturing carbon dioxide (CO2) from coal-fired power plants, Rice University scientists have found that CO2 can be removed more economically using ?waste? heat - low-grade steam that cannot be used to produce electricity. The find is significant because capturing CO2 with conventional technology is an energy-intensive process that can consume as much as one-quarter of the high-pressure steam that plants use to produce electricity.
