Startup of the world’s first integrated CCS of coal-fired power plant
By Gerald Ondrey |
A carbon capture and sequestration (CCS) demonstration project jointly under way by Mitsubishi Heavy Industries, Ltd. (MHI; Tokyo, Japan; www.mhi.co.jp) and Southern Company, a major U.S. electric utility, has begun underground injection of carbon dioxide recovered from emissions from a coal-fired power generation plant. 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 impurity — on a scale of 500 metric tons per day (m.t./d). Based on the results, MHI intends to provide highly reliable system ahead of other companies and contribute to efforts to solve global warming issue.
The demonstration project calls for the capture and compression of CO2 from the fluegas of a coal-fired plant by a CO2 capture facility built at Southern Company’s Plant Barry in Alabama, and its sequestration in a saline formation at a depth of 3,000–3,400 m in the Citronelle Dome geologic structure, which is approximately 12 miles west from the plant. The sequestration aspect of the project is being conducted as Phase III of the Regional Carbon Sequestration Partnerships program, a program sponsored by the U.S. Department…
