Petra Nova, the world’s largest post-combustion carbon capture system on a retrofitted coal-fired power plant, successfully begins commercial operations. The Houston, Texas electric generating station captures carbon dioxide and uses it for enhanced oil recovery at a depleted oil field 80 miles away. Petra Nova’s success includes capturing over 3.27 million short tons of carbon dioxide, sending it into associated storage, and producing over 3.3 million barrels of oil through enhanced oil recovery at the depleted oil field. The project is part of the Department of Energy’s Clean Coal Power Initiative program. (DOE)
