Mitsubishi Heavy Industries, Ltd. (MHI) and Southern Company, a major U.S. electric utility, will jointly demonstrate a plant to test technology enabling recovery of between 100,000 and 150,000 metric tons of carbon dioxide (CO2) per year from flue-gas emissions from a coal-fired power generation plant.
The demonstration, involving the equivalent of emissions from 25 megawatts of the plants generating capacity, is scheduled to begin operating by the first quarter of 2011. While the technology to recover and compress CO2 from natural gas-fired flue gas has already been applied commercially, the planned development and demonstration testing of the plant in the application of CO2 recovery from flue gas of coal-fired generation plant, which contains more impurities, will be on a scale unprecedented anywhere in the world.
Based on the test results, MHI will pursue the CO2 recovery/compression technology needed for commercial-scale carbon capture.
The host site for the carbon capture project is Plant Barry, a unit of Southern Company subsidiary Alabama Power. The MHI carbon capture technology will be installed on an existing unit of the plant, with the CO2 captured in the demonstration transported by pipeline and injected underground at a site away from the plant grounds. The U.S. Department of Energys (DOE) Southeast Regional Carbon Sequestration Partnership will be responsible for the transport and sequestration.
The Electric Power Research Institute and other partners are participating in the project. Southern Company is approaching other electricity providers to join as well.
Specifically, MHI will be responsible for plant engineering, equipment supply, and provision of technical support during the demonstration phase.
The CO2 recovery and compression process consists of various facilities, including those for high-performance pre-processing desulfurization, flue gas CO2 recovery, recovered CO2 compression and utility.
Because the project is based in the United States, the detailed engineering and procurement activities will be provided by Mitsubishi Heavy Industries America, Inc., a wholly owned subsidiary of MHI from their engineering office based in Austin, Texas.
