The U.S. Department of Energy recently announced a funding opportunity of $171.5 million to support next-generation geothermal field-scale tests for both electricity generation and exploration drilling to support characterization and potential confirmation of promising geothermal prospects.
The funding opportunity includes six topics with varied levels of funding and awards anticipated. For the first round of applications, two of the six topics will be open, seeking field tests for enhanced geothermal systems and drilling for next-generation and hydrothermal resource characterization/confirmation.
Although the United States leads the world in geothermal electricity capacity with about four gigawatts, DOE analysis shows the potential for at least 300 gigawatts of reliable, flexible geothermal power on the U.S. grid by 2050.
Projects under this opportunity are expected to help derisk geothermal development approaches and locations nationwide, which can encourage private investment, spur industry growth, and help realize the country’s geothermal potential, it said.
Letters of Intent for the opportunity are due March 27, 2026, and full applications are due April 30, 2026.
