EPRI begins validating CCS at 1,300 MW coal-fired plant

29 September 2009– The Electric Power Research Institute (EPRI) joined with American Electric Power (AEP) and Alstom in a validation of one of the nation’s first carbon dioxide capture and storage (CCS) technologies at AEP’s Mountaineer Plant in West Virginia.

The 20 MW CCS system was installed at the 1,300 MW Mountaineer Plant, where it will remove approximately 100,000 metric tons of carbon dioxide (CO2) emissions annually from the flue gas stream of the plant for up to five years. The captured CO2 will be compressed and injected into two saline reservoirs located 7,800 feet underground.

EPRI will conduct independent evaluations of the capture process and manage a group of utility participants. The data will support efforts to create commercial-scale CCS technologies and provide information to the public and industry.

The Mountaineer project will also validate how well Alstom’s chilled ammonia process works, which may reduce parasitic loads on electric generators. A smaller-scale version is being tested at We Energies on a 1.7 MW slipstream at the Pleasant Prairie plant in Wisconsin.
