Mitsubishi Heavy Industries Ltd. (MHI) and Southern Company, a major U.S. power company, will jointly launch a field test in 2011 to recover high-purity carbon dioxide (CO2) from coal-fired flue gas.

The two companies will set up a CO2 recovery demonstration plant, which is designed to be built at a medium-scale thermal power station in Alabama, the US. Based on the results of this demonstration plant, they will aim to commercialize the recovery plant in the future.

The field test will be subsidized by the US government. The demonstration plant will be constructed in Plant Barry, a coal-fired power station owned by Southern's subsidiary Alabama Power. Recovered CO2 will be compressed and stored in an aquifer deep underground.
