Carbon Capture: The Path to Cleaner Coal
Content provided by Southern Company
Coal is the workhorse of the electric power industry, the fuel that accounts for about 50 percent of the nation's electricity generation. Carbon dioxide would be "captured" during the generation process and either permanently stored underground or re-used in other industrial applications.
Solvents can selectively find and capture carbon dioxide in flue gas or pre-gassified coal. During a pilot at Plant Yates in Georgia, a small amount of carbon dioxide was captured using this method that absorbs CO2, and then returned to the plant's flue gas.
Carbon dioxide is already being injected throughout the United States into underground geologic formations to drive out desirable fuels, like oil and gas. It can also be injected into pore space found in underground rocks.
