![]() ![]() ![]() The Petra Nova carbon emissions reduction system uses an amine-based absorption system, or the KM CDR Process (Kansai Mitsubishi Carbon Dioxide Recovery). Due primarily to outages of the host natural gas cogeneration unit, the project missed its carbon sequestration goal by 17% over its first three years of operation. On May 1, 2020, NRG shut down Petra Nova, citing low oil prices during the COVID-19 pandemic. To satisfy the Clean Coal Power Initiative requirements, the Texas Bureau of Economic Geology put a monitoring plan in place to keep track of the injection and movement of the CO 2 beneath the surface and in the rock structures at West Ranch. This project was expected to run for at least another 20 years. With the new injection of high pressure carbon dioxide into the field, the oil production of the field was increased by a factor of 50 to 15,000 barrels per day. The oil field had previously been producing 300 barrels of oil per day. The carbon dioxide gas was captured at 99% purity, and is then compressed and piped about 82 miles to the West Ranch Oil Field, where it is used for enhanced oil recovery. The project was designed to annually capture approximately 33% of the carbon dioxide (CO 2) (or 1.6 million tonnes) emissions from the plant's boiler #8. The plant entered commercial service in 1977, and the new carbon emissions reduction system was first put into operation on January 10, 2017. It was a multi-million dollar project taken up by NRG Energy and JX Nippon Oil to retrofit one of the boilers at their WA Parish Generating Station with a post-combustion carbon capture treatment system to treat a portion of the atmospheric exhaust emissions from the retrofitted boiler. Petra Nova was a carbon capture project designed to reduce carbon emissions from one of the boilers of a coal burning power plant in Thompsons, Texas. carbon-capture project Petra Nova shown on the right. ![]()
