Columbus, Ohio, July 14, 2011 — American Electric Power is terminating its cooperative agreement with the U.S. Department of Energy and placing its plans to advance carbon dioxide capture and storage (CCS) technology to commercial scale on hold, citing the current uncertain status of U.S. climate policy and the continued weak economy as contributors to the decision.
"We are placing the project on hold until economic and policy conditions create a viable path forward," said Michael G. Morris, AEP chairman and chief executive officer. "With the help of Alstom, the Department of Energy and other partners, we have advanced CCS technology more than any other power generator with our successful two-year project to validate the technology. But at this time it doesn't make economic sense to continue work on the commercial-scale CCS project beyond the current engineering phase."
In 2009, AEP was selected by the Department of Energy to receive funding of up to $334 million through the Clean Coal Power Initiative to pay part of the costs for installation of a commercial-scale CCS system at AEP's Mountaineer coal-fueled power plant in New Haven, W.Va.
The system would capture at least 90 percent of the carbon dioxide from 235 MW of the plant's 1,300 MW of capacity. The captured carbon, about 1.5 million metric tons per year, would be treated and compressed, then injected into suitable geologic formations for permanent storage about 1.5 miles below the surface.
Plans were for the project to be completed in four phases, with the system to begin commercial operation in 2015. AEP has informed the DOE that it will complete the first phase of the project (front-end engineering and design, development of an environmental impact statement and development of a detailed Phase II and Phase III schedule) but will not move to the second phase.
DOE's share of the cost for completion of the first phase is expected to be about $16 million, half the expenses that qualify under the DOE agreement.
AEP and partner Alstom began operating a smaller-scale validation of the technology in October 2009 at the Mountaineer Plant, the first fully-integrated capture and storage facility in the world. That system captured up to 90 percent of the carbon from a slipstream of flue gas equivalent to 20 MW of generating capacity and injected it into suitable geologic formations for permanent storage about 1.5 miles below the surface.
The validation project, which received no federal funds, was closed as planned in May after meeting project goals. Between October 2009 and May 2011, the life of the validation project, the CCS system operated more than 6,500 hours, captured more than 50,000 metric tons of carbon and permanently stored more than 37,000 metric tons of carbon.
