Petra Nova - WA Parish Generating Station

Background

Petra Nova, a 50/50 joint venture between NRG and JX Nippon Oil & Gas Exploration, operates a commercial-scale post-combustion carbon capture facility at NRG's WA Parish generating station southwest of Houston, Texas.

Solution

This facility captures more than 90 percent of the carbon dioxide (CO2) from a 240 MW slipstream of flue gas for the use and ultimate sequestration of 1.6 million tons of this greenhouse gas annually. Petra Nova came online in 2016.

The technology has the potential to enhance the long-term viability and sustainability of coal-fueled power plants across the U.S. and around the world. The project was selected by the United States Department of Energy (DOE) to receive up to $190 million as part of the Clean Coal Power Initiative Program (CCPI), a cost-shared collaboration between the federal government and private industry.

The Petra Nova Project utilizes a proven carbon capture process, which was jointly developed by Mitsubishi Heavy Industries, Ltd. (MHI) and the Kansai Electric Power Co., that uses a high-performance solvent for CO2 absorption and desorption.

The Captured CO2 will employ Enhanced Oil Recovery to enhance production at the West Ranch oil field, which is operated by Hilcorp Energy Company. It is expected that oil production will be boosted from around 300 barrels per day today to up to 15,000 barrels per day while also sequestering CO2 underground. This field is currently estimated to hold approximately 60 million barrels of oil recoverable from EOR operations
