A STEP closer to transformational electric power
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 started in late 2023 to illustrate the performance of this high-efficiency power cycle over a range of operating conditions.

Flexible & reliable power
Broad applicability across multiple low- and zero-emission heat sources offers cleaner power that improves grid stability and resiliency
Efficient & versatile
This first-of-a-kind pilot power plant will demonstrate how sCO2 technology produces electricity in a more cost effective and efficient way with smaller turbo-machinery and lower emissions.
Become a project partner
This open project is welcoming new partners from around the world. OEMs, engineering companies, and power plant owner/operators are invited to join to gain a better understanding of how sCO2 technology can improve high-efficiency power generation.
