CO-2 Compression Research Advancing At SwRI
Coal is used to generate about half of all electricity consumed in the U.S. Unfortunately, coal contains high carbon content and produces double the CO-2 emissions when burned compared to natural gas. Because of growing concern over greenhouse gas emissions, the U.S. government and utilities are developing technologies to separate carbon dioxide both pre-and post-combustion.
