PALO ALTO, Calif.–(BUSINESS WIRE)–The Electric Power Research Institute (EPRI) announced today that five electric utilities in the United States and Canada have joined EPRI to host studies of the impacts of retrofitting advanced amine-based post-combustion carbon dioxide (CO2) capture technology to existing coal-fired power plants. In addition to the five host site companies, 15 other companies and organizations, including six from Canada and one from Australia, have joined the project.
The five host companies and sites include Edison Mission Groups 1,536-megawatt (MW) Powerton Station, operated by Midwest Generation, in Pekin, Ill.; Great River Energys 1,100-MW Coal Creek Station in Underwood North Dakota; Nova Scotia Powers two 160-MW units at its Lingan Generating Station in Lingan, Nova Scotia; Intermountain Power Agencys 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.
As global demand for electricity increases and regulators worldwide look at ways to reduce CO2 emissions, post-combustion capture (PCC) for both new and existing units could be an important option. However, retrofit of PCC to an existing plant presents significant challenges, including limited space for new plant equipment, limited heat available for process integration, additional cooling water requirements and potential steam turbine modifications.
