Southwest Research Institute's CCUS and Clean Energy Development: Oxy-fuel Combustion and Advanced Power Generation Turbines
Electric power generation contributes about 1/3 of all U.S. carbon emissions. Southwest Research Institute and its partners are developing advanced power generation utilizing supercritical carbon dioxide (sCO2) instead of steam to improve efficiencies of both traditional fossil powered plants as well as concentrating solar power (CSP) plants. A new generation concept direct fires the fuel with oxygen (so called oxy-fuel combustion) in the turbine, similar to a traditional gas turbine, but utilizing the CO2 instead of air as the working fluid and does so at much higher pressures. This highly recuperated cycle offers state-of-the-art efficiencies (approaching 60%), while capturing 98% of the CO2 with no additional power penalty associated with traditional capture schemes. This talk will discuss the development of a 300 MWe oxy-fuel turbine, as well as combustion, heat transfer, and material test rigs to support its development.
