Mitsubishi Heavy Industries and Southern Company Services successfully completed a demonstration project that captured and sequestered carbon dioxide (CO2) from a coal-fired power plant. MHI will now seek to make the technology commercially viable.
Both companies built the demo at Southern Co.’s (NYSE: SO) 2,657 MW Plant Barry in Alabama to be able to handle 500 metric tons per day (mtpd) of CO2. The plant uses a flue gas scrubeer, flue gas CO2 capture/regeneration system, CO2 compression machinery and electrical components. It has the capacity to recover 150,000 metric tons of CO2 per year with recovery efficiencies of more than 90 percent. MHI developed the KM-CDR technology that uses a 25 MW flue gas slip from Plant Barry to capture the CO2, transport it 12 miles to the Citronelle Dome and inject it underground.
The demonstration began in June 2011. The technology was verified for recovering CO2 from the flue gas, as well as recovery performance, integrated capture and sequestration demonstration testing began in August 2012. It was jointly developed by the U.S. Department of Energy, Southern, MHI and the Electric Power Research Institute.
