For the ATB, coal-CCS technology is ultra-supercritical pulverized coal technology fitted with CCS. Both 30% capture and 90% capture options are included for the coal-CCS technology. The CCS plant configuration includes only the cost of capturing and compressing the CO 2. It does not include CO 2 delivery and storage.
Fossil fuel fired electric generating plants are the cornerstone of America's central power system. Currently, the existing fossil fuel fleet accounts for about two-thirds of all electricity generated domestically, over 30% from coal alone. Electricity demand is expected to increase dramatically over the next 30 years with the growth of the manufacturing sectors.
