Company/Alliance: Alstom, Electric Power research Institute (EPRI) and We Energies.
Location: Pleasant Prairie, Milwaukee, US
Feedstock: Coal
Size: 5 MW slip stream
Capture Technology: Post-combustion with chilled ammonia
CO2 Fate: Sequestration into a deep saline formation below the site
Timing: Pilot operation (2008)
Motivation/Economics: The project is a combined ten-year effort with the US Department of Energy’s (DOE). The DOE’s Office of Fossil Energy contributed $7.2 million while Alstom and AEP contributed $1.4 million for the initial phases of the project. Geologic investigation of the Mountaineer site cost $4.2 million.
Comments: The pilot project in West Virginia is planned to operate for 12 to 18 months. Meanwhile, AEP will collaborate with Babcock & Wilcox on developing oxyfuel combustion technology at its 30 MW Clean Environment Development Facility in Alliance, Ohio. So far the project has run some 4,600 hours continuously without issue and captured some 18,000 tons of CO2 over the last year. It has sucessfully proven to capture over 88% of CO2.
