GTI Energy and partners Southwest Research Institute (SwRI) and GE Research are revolutionizing future power generation with design and construction of the 10 MWe Supercritical Transformational Electric Power (STEP) Demo pilot plant. The project is being funded by the U.S. Department of Energy/National Energy Technology Laboratory (U.S. DOE/NETL) and numerous other industry partners.

Mechanical construction is complete on this next-generation pilot plant test facility in San Antonio, Texas, enabled by supercritical CO2 technology. The project successfully achieved sCO2 fluid conditions in early 2023, and full-scale testing will begin in early 2024 to illustrate the performance of this high-efficiency power cycle over a range of operating conditions.

“GTI Energy is proud to catalyze innovation and collaboration to enable power generation to contribute to clean, efficient, and reliable energy. The STEP Demo pilot is demonstrating the efficiency and emissions benefits of supercritical carbon dioxide technology in transforming electric power generation.”
