The world’s largest operating post-combustion carbon dioxide (CO2) capture system Petra Nova celebrates its third anniversary Jan. 10, 2020. The project, supported by the U.S. Department of Energy (DOE) Office of Fossil Energy and administered by NETL, is demonstrating how carbon capture, utilization, and storage technologies can economically support the flexibility and sustainability of fossil fuels at commercial scale. Owned and operated by NRG Energy Inc. and JX Nippon Oil and Gas Exploration Corporation, Petra Nova is located southwest of Houston Texas and applies carbon capture technology to an existing unit at the coal-fired W.A. Parish Generating Station. Commencing operation in 2017, the Petra Nova project addresses capture and beneficial reuse of CO2 from coal-based electricity production. The project uses an advanced amine-based process to capture CO2, which is then compressed, dried, and transported for enhanced oil recovery (EOR) at the West Ranch Oil Field in Jackson County, Texas, to boost oil production.
