Advanced Research Projects Agency - Energy (ARPA-E), U.S. Department of Energy
About this opportunity
The NOFO was modified and an updated SF-424A/Budget Justification Workbook was uploaded February 6, 2026.Encourage/Discourage notification letters were released and the Full Application NOFO was posted January 28, 2026.The SUPERHOT program will support the research and development of technologies that enable the production of geothermal energy from super-hot reservoirs (>375 °C and >22 MPa) for 15 years or more. This program seeks to fund the development of novel technologies for well construction, enhance testing facilities, and optimize reservoir heat extraction to make super-hot geothermal production a reality. The program will have two categories: The program will have two categories:Category 1: Technologies related to the construction of robust super-hot wells and validation services ...
