Supercritical Carbon Dioxide (sCO₂) power cycles are a transformational technology for the energy industry, providing a higher efficiency heat source energy conversion for conventional and alternative energy sources. The novel cycle significantly reduces capital costs because of smaller equipment footprints and design modularity and allows for rapid cyclic load and source following to balance solar and wind energy power swings. This topical report outlines progress made to develop an oxy-fuel combustion turbine to significantly improve the state-of-the-art for thermal efficiency and results in a high-pressure stream of CO₂ simplifying carbon capture making the power plant emission-free.The team of Southwest Research Institute® (SwRI®), General Electric Global Research Center (GE-GRC), 8 Rivers, Air Liquide, Electric Power Research Institute, Inc. (EPRI), and Georgia Tech are working to develop a conceptual design for a sCO₂, coal syngas or natural gas-fired oxy-fuel turbine in the 150-300 MWe size range capable of 1,200°C turbine inlet temperature at 300 bar and exhaust temperatures in the 725-775°C range. This turbine will require cooled turbine nozzles and blades as well as advanced thermal management systems to accommodate these high temperatures. The team represents world leaders in the development of sCO₂ power technologies and has received numerous Department of Energy (DOE) and industry-funded projects to implement pilot scale sCO₂ power cycle component and system level equipment, as well as MW scale pilot plants.
