STEP Demo (IMAGE) Southwest Research Institute Caption SwRI’s John Klaerner, lead turbine engineer, and Dr. Jeff Moore, the principal investigator of the STEP Demo project, are pictured with the recently assembled sCO2 turbine for the 10 MWe demonstration plant under construction at SwRI. The facility, developed through a collaboration between SwRI, GTI Energy, GE Research and the U.S. Department of Energy/National Energy Technology Laboratory (DOE/NETL), has achieved its first operation with CO2 at supercritical fluid conditions in its compressor section, which represents significant progress toward readying the facility for system-level testing.
