Mitsubishi Heavy Industries America declared that a 25 MW carbon capture and sequestration facility at Plant Barry power plant of Southern Company has commenced operations.
500 ton/day CO2 capture facility at Southern Company's Plant Barry
Alabama Power, a subsidiary of Southern Company, owns and operates Plant Barry located in Mobile, Alabama.
The carbon capture plant, recognized as the largest facility of its kind in the world, uses the KM CDR Process capture technology, which was co-developed by The Kansai Electric Power and Mitsubishi Heavy Industries. Southern Company partnered in the development of the carbon capture facility, which can capture nearly 500 tons of CO2 per day in a deep saline geologic form for permanent underground storage.
The KM CDR Process technology utilizes a unique solvent known as KS-1 to entrap CO2 from a flue gas stack. During the process, the solvent reacts and entraps the CO2, which can be isolated from the solvent and compressed for transportation through pipeline.
The Southeast Regional Carbon Sequestration Partnership will transport the captured CO2 through a pipeline to the Citronelle Oil Field where the gas will be injected 9,500 ft. below the ground. This process makes the gas to be stored permanently in the geologic formation. Denbury Resources is the operator of the Citronelle Oil Field.
The President and Chief Executive Officer at Mitsubishi Heavy Industries America, Mitch Morimoto commented that the carbon capture facility is an important landmark and is part of the company’s strategy to promote the KM CDR Process CO2 technology.
