Pressure and temperature record broken for sCO₂ materials testing

Pressure and temperature record broken for sCO₂ materials testing

Southwest Research Institute (SwRI) has achieved a significant milestone, reaching new temperature records for testing materials in high-pressure environments. While conducting material testing for a high-pressure, high-temperature supercritical carbon dioxide (sCO2) turbine, SwRI achieved unprecedented conditions of 1,150 degrees Celsius (2,100 degrees Fahrenheit) at 300 bar (4,350 psi). These are the highest published temperature and pressure …

SwRI sets new benchmark in high temperature pressure testing for sCO2 turbines

Los Angeles CA (SPX) May 21, 2025 Southwest Research Institute (SwRI) has established a new high mark in materials testing by reaching 1,150 degrees Celsius at 300 bar pressure during supercritical carbon dioxide (sCO2) turbine development. This surpasses previous benchmarks and represents the highest recorded temperature and pressure ever published for sCO2 environments. The achievement stems from a $6.4 million U.S. Depa
