EPRI to study carbon capture at five coal-fired plants

27 January 2009 – The Electric Power Research Institute (EPRI) said five utilities in the U.S. and Canada will host studies examining the effects of retrofitting advanced amine-based post-combustion carbon dioxide capture technology to existing coal-fired power plants. Fifteen other companies and organizations joined the project.

The five host sites include Edison Mission Group’s 1,536 MW Powerton Station, operated by Midwest Generation, in Pekin, Ill.; Great River Energy’s 1,100 MW Coal Creek Station in Underwood N.D.; Nova Scotia Power’s two 160 MW units at its Lingan Generating Station in Lingan, Nova Scotia; Intermountain Power Agency’s 950 MW Intermountain Generation Station in Delta, Utah; and the 176 MW circulating fluidized bed boiler Unit 1 at FirstEnergy’s Bay Shore Plant in Oregon, Ohio.

Each site offers a variety of unit sizes and ages, existing and planned emissions controls, fuel types, steam conditions, boilers, turbines, cooling systems and options for CO2 storage. The five studies will be conducted in 2009. A report for each site will assess the most practical CO2 capture efficiency configuration based on site constraints; determine the space required for the CO2 capture technology and the interfaces with existing systems; estimate performance and costs for the PCC plant; and assess the features of each plant that materially affect the cost and feasibility of the retrofit.

EPRI’s CoalFleet for Tomorrow program is already conducting technical and economic assessments of ways to reduce CO2 emissions in new, advanced coal-based generation. This new program will apply that knowledge to assess the suitability of retrofitting advanced amine PCC to plants currently in operation and to guide the design of plants under development.
