NRG Energy, Inc. and JX Nippon Oil & Gas Exploration Corporation have completed construction of Petra Nova, which the companies said is the world’s largest post-combustion carbon capture, located at NRG's WA Parish generating station southwest of Houston, Texas.
NRG said that Petra Nova first captured carbon dioxide (CO2) on September 19, 2016 and has delivered more than 100,000 tons of captured CO2 to the West Ranch field through an 80-mile pipeline.
Final performance acceptance testing on the facility was completed on December 29, 2016 and the facility turned over for operations. During performance testing, the system met all performance criteria including capturing more than 90% of CO2 from a 240 MW equivalent slipstream of flue gas off an existing coal-fueled electrical generating unit at the WA Parish power plant in Fort Bend County, southwest of Houston, NRG said
At this level of operation, Petra Nova can capture more than 5,000 tons of CO2 per day, NRG said
NRG noted that the facility, located outside of Houston, was developed in a, "competitive energy environment."
"NRG and JX Nippon’s Petra Nova is the type of innovative, technologically advanced project that proves time and again that Texas is the world leader in energy innovation," said Greg Abbott, Governor of the State of Texas.
Hilcorp Energy Company (Hilcorp), the operator of West Ranch oilfield, will use the captured CO2 to boost production at West Ranch oilfield, jointly owned by NRG, JX Nippon and Hilcorp.
Petra Nova is 50-50 joint venture by NRG and JX Nippon. Additionally, the United States Department of Energy (DOE) is providing up to $190 million in grants as part of the Clean Coal Power Initiative Program (CCPI). A portion of the project was financed with project loans from the Japan Bank for International Cooperation (JBIC) and Mizuho Bank, backed by Nippon Export and Investment Insurance (NEXI).
