Reducing CO2 Emissions from Coal-Fired Power Plants
Demonstration of Improvements : EPRI’s UltraGen Initiative
• Series of three commercial power projects and a test facility that progressively advance USC, NZE, and CCS technology
– UltraGen I—800 MW net, main steam 1120°F, 25% CO2 capture
– UltraGen II—600 MW net, main steam 1290°F, 60% CO2 capture
– ComTes-1400 to test materials and components for UltraGen III
– UltraGen III—600 MW net, main steam 1400°F, 90% CO2 capture
• The UltraGen projects are commercial units dispatched by their hosts (i.e., the host operates them for profitability) that incorporate technology demonstration elements
– Host’s incremental cost for new technology elements will be covered by tax credits and funds from industry-led consortium
EPRI Role in Demonstrating Improved Post-Combustion CO2 Capture Technologies
• Supporting test program for Alstom’s chilled ammonia process at two locations
– 1.7-MW pilot plant at We Energies’ Pleasant Prairie power plant
– 20-MW ―product validation facility‖ at AEP’s Mountaineer plant that captures and stores over 120,000 tons/year of CO2.
• Supporting test program for MHI’s advanced amine process at a Southern Company’s Plant Barry, near Mobile, Alabama
– 25-MW facility that captures and stores over 150,000 tons/year of CO2 in support of Southeast Regional Carbon Sequestration Partnership Program (SECARB).
• Supporting DOE’s National Carbon Capture Center in Wilsonville, Alabama
– Supporting development of improved pre- and post-combustion capture technologies.
• CO2 capture from flue gas has been carried out at small scale (~20 MW) for high-value applications in chemical and food industries.
• For power industry need larger plants that minimize increase in cost of electricity
– Current designs are estimated to result in a 60 percent increase.
• Part of the approach to reduce costs is to increase power generating efficiency and lower CO2 emitted per MWh
– This benefits both post-combustion and oxy-combustion.
– Post combustion also requires improved solvents.
• EPRI is increasing its effort in oxy-combustion and is supporting Air Products in demonstrating the ion transfer membrane technology as a more cost-effective alternative to cryogenic separation.
