Project Timeline

Project Description

Petra Nova Parish Holdings, a joint venture between NRG Energy and JX Nippon Oil and Gas Exploration, will retrofit a CO2 capture plant on an existing coal-fired power plant (W.A. Parish Generating Station) located in Thompsons, Texas, which is southwest of Houston. The project will demonstrate the ability of the CO2 capture technology supplied by Mitsubishi Heavy Industries (MHI) to capture 90% 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 propetary KS-1™ solvent that facilitates low energy requirements, solvent consumption, and 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, this will be the largest post-combustion CO2 capture project installed on an existing coal-fueled power plant. This project has the potential to enhance the long term viability and sustainability of coal-fueled power plants across the United States and worldwide. The University of Texas, Bureau of Economic Geology will design and manage the CO2 monitoring plans for this project.

Project Benefits

The project addresses capture of CO2 from coal-based electricity production and its beneficial reuse as required by the CCPI-3B solicitation. The project will achieve these requirements through the implementation of an advanced amine-based carbon capture process and reuse of the captured CO2 in an Enhanced Oil Recovery (EOR) application. The project will demonstrate that post-combustion CO2 capture and reuse can be done economically for existing plants when the plant has the opportunity to recover oil from nearby oilfields.

The captured CO2 will be used to enhance oil production at the West Ranch Oil Field, where it will remain sequestered 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. It is estimated that the field holds 60 million barrels of oil recoverable from EOR operations.

Project Status

The construction of the project is currently underway, and it is expected to be operational in late 2016.
