The Southwest Research Institute (SwRI), based in the US state of Texas, has recorded the highest temperature and pressure conditions ever reached in materials testing for supercritical carbon dioxide (sCO2) – a state of carbon dioxide that behaves like both a gas and a liquid.
It is a breakthrough that could advance the potential for more efficient and scalable power generation using sCO2, which is a technology that harnesses the unique properties of CO2 in a supercritical state to improve energy transfer.
While conducting material testing for a high-pressure, high-temperature sCO2 turbine, SwRI achieved conditions of 1,150°C at 300-bar. Before this, the highest recorded pressure and temperature for sCO2 was 800°C at 300-bar. The oxy-fuel turbine was designed to operate at a maximum temperature of 1,150°C.
