Project Timeline

Project Description

Petra Nova Parish Holdings, a joint venture between NRG Energy and JX Nippon Oil and Gas Exploration, has retrofitted an existing coal-fired power plant (W.A. Parish Generating Station) located southwest of Houston, in Thompsons, Texas with a CO2 capture plant. The project is demonstrating the ability of the CO2 capture technology supplied by Mitsubishi Heavy Industries (MHI) to capture 90 percent of the CO2 emitted from a 240-megawatt-electrical (MWe) flue gas stream. The MHI CO2 capture technology, called the KM CDR Process®(Kansai Mitsubishi Carbon Dioxide Recovery), was jointly developed by MHI and the Kansai Electric Power Company. This process uses the proprietary KS-1™ solvent, which facilitates low energy requirements, low solvent consumption, and low waste products when compared with a conventional solvent.

The project is designed to capture and store 1.4 million tonnes of CO2 per year. At 240 MWe, the project is the largest post-combustion retrofit of an existing coal-fueled power plant with a CO2 capture plant and has the potential to enhance the long-term viability and sustainability of coal-fueled power plants across the United States and throughout the world. The University of Texas Bureau of Economic Geology has designed and is managing the CO2 monitoring plans for this project.

Project Benefits

The project addresses the capture of CO2 from coal-based electricity production and its beneficial reuse via an advanced amine-based carbon capture process and reuse of the captured CO2 in an enhanced oil recovery (EOR) application. The project is demonstrating that post-combustion CO2 capture and reuse can be done economically for existing plants when there is an opportunity to recover oil from nearby oilfields.

The captured CO2 is being used to enhance oil production at the West Ranch Oil Field, where it will remain stored underground as a result of EOR operations. The project is expected to boost production at West Ranch from 500 barrels per day to approximately 15,000 barrels per day. The field holds an estimated 60 million barrels of oil recoverable from EOR operations.

Project Status

The project began commercial operations on January 10, 2017.
