In Illinois, western Indiana, and western Kentucky, more than 304 million metric tons of carbon dioxide are released annually from stationary sources. These sources include ethanol plants, electric power plants, refineries, cement plants, and other industrial facilities.
Using various technical processes, it is possible to capture and separate CO2 from the flue gas and process streams of these stationary sources, harvesting CO2 for oil recovery and even beverage carbonation. However, this technology has never been deployed at the scale necessary to significantly reduce carbon dioxide emissions. Research is currently being conducted to reduce the cost and improve the performance of capturing carbon technology, using membranes, sorbents, new solvents, and other capture mechanisms.
