A carbon capture and sequestration (CCS) demonstration project jointly under way by Mitsubishi Heavy Industries Ltd. (MHI) and Southern Co., a major U.S. electric utility, has begun underground injection of carbon dioxide recovered from emissions from a coal-fired power generation plant, MHI announced on Sept. 14.
MHI said the event marks an important milestone in the world's first integrated CCS project for flue gas from a coal-fired power plant--which contains significant quantities of impurities--on a scale of 500 metric tons per day.
The demonstration project calls for the capture and compression of CO2 from the flue gas of a coal-fired plant by a CO2 capture facility built at Southern's Plant Barry in Alabama, and its sequestration in a saline formation at a depth of 3,000-3,400 meters.
MHI said through the project it intends to show the high-level economic feasibility and reliability of its technology, including the commercial-scale capture of coal-fired power plant flue gas, and looks to realize its commercialization.
