Coal-powered facilities account for roughly a third of all U.S. emissions of carbon dioxide, and most climate scientists believe that the buildup of carbon dioxide and other greenhouse gases in the atmosphere could have costly consequences. One much-discussed option for reducing the nation’s carbon dioxide (CO2) emissions while preserving its ability to produce electricity at coal-fired power plants is to capture the CO2 that is emitted when the coal is burned, compress it into a fluid, and then store it deep underground.
