Overview
- ARPA‑E named eight candidate teams on November 12 that could share up to $30 million under the SUPERHOT program, starting formal DOE negotiations rather than issuing final awards.
- SUPERHOT targets technologies that can operate above 375°C and roughly 22 megapascals of pressure to more than triple output from individual geothermal wells and enable deeper, higher‑temperature production.
- Selected teams include national labs, universities, and private firms such as XGS Energy, with XGS saying it will adapt its thermally conductive cement and closed‑loop well design for superhot conditions and building on a separate September DOE selection for a New Mexico appraisal well.
- Selections are conditional: DOE and applicants must complete negotiations and technical validation before funding is released, and DOE may cancel talks or rescind choices during that process.
- DOE projects estimate the U.S. has about 15,000 GW of subsurface geothermal potential versus under 4 GW in current utility output, so successful SUPERHOT demonstrations could cut baseload costs, boost grid reliability, and drive new manufacturing and drilling work if the technologies scale.
