A STEP closer to transformational electric power
The 10-megawatt (MWe) Supercritical Transformational Electric Power (STEP) Demo pilot plant in San Antonio, Texas, has successfully completed phase 1 testing, demonstrating operability, efficiency, and commercial readiness of the supercritical carbon dioxide (sCO2) power cycle in a simple recuperating configuration. The pilot plant achieved full operational speed of 27,000 RPM at 500° C, meeting test objectives and targets. It generated 4 megawatts (MWe) of grid synchronized power—enough to supply electricity to 4,000 homes.
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.
