A new funding initiative from the U.S. Department of Energy is reinforcing momentum behind next-generation geothermal technologies, with up to $171.5 million allocated for field tests and exploration drilling. The program is designed to support large-scale demonstration projects, helping validate emerging geothermal systems and reduce the cost and risk associated with subsurface exploration.
The funding targets two critical stages of geothermal development. First, it supports field-scale testing of next-generation systems capable of operating at temperatures and depths required for commercial power production. Second, it funds exploration and confirmation drilling, which gathers geological data needed to identify viable geothermal reservoirs and accelerate project deployment.
Individual project awards are expected to range between $4 million and $25 million, with as many as 28 projects potentially funded in the first round. Letters of intent are due in March 2026, with full applications expected by the end of April.
Importantly, the initiative includes both enhanced geothermal systems (EGS) and closed-loop technologies, two approaches that aim to unlock geothermal resources far beyond traditional hydrothermal regions. By supporting real-world testing and subsurface characterization, the program aims to close key technology gaps and accelerate the commercialization of geothermal power.
For the global geothermal sector, programs like this signal a growing recognition that firm, 24/7 clean energy sources will be essential to support future electricity demand, particularly as digital infrastructure and industrial electrification continue to expand.
