SUPERHOT

Funds United States geothermal R&D teams developing super-hot reservoir technologies through ARPA-E cooperative agreements.

ARPA-E administers SUPERHOT as a U.S. Department of Energy financial-assistance Notice of Funding Opportunity under Assistance Listing 81.135. The program supports research and development of technologies that enable production of geothermal energy from super-hot reservoirs above 375 C and 22 MPa for 15 years or more. The official facts describe two core categories: robust well construction and he

Research and development for super-hot geothermal reservoirs, including robust well construction, high-temperature materials, casing and cement systems, heat extraction, reservoir engineering, enhanced geothermal systems, advanced geothermal systems, and baseload geothermal power.
