NET Power announced a plan to develop and build its first utility-scale natural gas-fired plant with carbon capture and sequestration (CCS). The NET Power capture system utilizes the Allam-Fetvedt Cycle, combusting natural gas with oxygen, and uses supercritical carbon dioxide as a working fluid to drive a turbine instead of steam. This theoretically eliminates all air emissions, including traditional pollutants and CO2 and inherently produces pipeline-quality CO2 that can be sequestered underground.
Expected to be online in 2026, the new 300 MW plant would be located near Occidental’s Permian Basin operations close to Odessa, Texas. Captured CO2 would be transported to a permanent underground sequestration location through Occidental’s existing Permian CO2 handling infrastructure.
There are several announced NET Power projects proposing to use the Allam-Fetvedt cycle. These include the 280 MW Broadwing Clean Energy Complex in Illinois and the 280 MW Coyote Clean Power Project on the Southern Ute Indian Reservation in Colorado.
