Carbon capture center operational

Southern Co. (NYSE: SO) said that its 25 MW carbon capture and storage facility at Alabama Power’s 2,657 MW Barry coal-fired power plant is operating and capturing carbon dioxide.

The system is designed to capture approximately 150,000 tons of carbon dioxide (CO2) annually for permanent underground storage in a deep saline geologic formation.

Carbon dioxide from the Barry plant is being captured using Mitsubishi Heavy Industries Ltd. technology KM-CDR, which uses an advanced amine solvent. The process begins with coal combustion that generates electricity, leaving a flue gas. The CO2 from the flue gas reacts with the amine solvent before being captured from the flue gas. It is then compressed, making it ready for pipeline transport.

Captured CO2 from the plant will be supplied to the Southeast Regional Carbon Sequestration Partnership, or SECARB, for transport by pipeline and injection 9,500 feet underground at a site within the Citronelle Oil Field. The site, about 11 miles from the plant, is operated by Denbury Resources.

The CO2 will remain below the surface, permanently trapped in the geological formation into which it was injected and is not being used for enhanced oil recovery.
