World’s Largest Carbon Capture Project

coal energy manageThe Department of Energy – in partnership with NRG Energy and JX Nippon – has begun construction on the first commercial-scale, post-combustion carbon capture retrofit project in the United States, the largest such project in the world.

NRG Energy, through its wholly owned subsidiary Petra Nova Holdings, has formed a 50/50 joint venture with JX Nippon to build and operate the Petra Nova Carbon Capture Project that will capture 90 percent of the carbon dioxide in the processed flue gas from an existing unit at the WA Parish power plant (pictured) in Fort Bend County, southwest of Houston.

DOE says there are no set timelines yet, but once completed, the project will capture about 1.4 million metric tons of CO2 annually from the existing coal-fired power plant.

After compressing the captured CO2, it will be transported via pipeline 80 miles away to a previously depleted oil field where the greenhouse gas will then be used to displace previously unreachable oil. Once the oil is separated from the CO2, the greenhouse gas will be injected back into the underground oil field for permanent storage.
