(English) Cryogenic Carbon Capture (CCC) is a highly innovative CO2 capture technology that has the potential to reduce carbon emissions from fossil-fueled power plants by 95–99%, at half the cost and energy of current state-of-the-art (Amine based) carbon capture processes. CCC also removes other pollutants, such as SOX, NOX, and mercury.

• The Cryogenic CO2 Capture (CCC) process dries and cools flue gas from existing systems, modestly compresses it, cools it to a temperature slightly above the point where CO2 forms a solid, expands the gas to further cooling, precipitates an amount of CO2 as a solid that depends on the final temperature, pressurizes the CO2, and lastly reheats the CO2 and the remaining flue gas by cooling the incoming gases. The final result is the CO2 in a liquid phase and a gaseous nitrogen stream. CO2 capture efficiency depends primarily on the pressure and temperature at the end of the expansion process.
• What are the ancillary benefits of CCC? In addition to the cost and energy efficiency advantages, the CCC process enjoys several ancillary benefits, including leveraging of existing capital investments, pollutant control, water savings, and potential energy storage.
