Fervo Energy wins $20m DOE grants for EGS projects in Idaho and Nevada
Fervo Energy has secured two US Department of Energy (DOE) grants totalling approximately $20 million to advance enhanced geothermal system (EGS) development across Idaho and Nevada. The awards cover drilling, reservoir appraisal, and the testing of new technology suited to high-temperature EGS operations, with national laboratory partners involved in the Idaho programme.
EGS generates electricity by injecting water into deep, hot rock formations, fracturing them to create a reservoir, and recovering the heat around the clock regardless of weather. Unlike conventional geothermal, which relies on naturally occurring hydrothermal conditions, EGS can be deployed in a much wider range of geological settings, making it one of the more promising sources of firm, zero-carbon baseload power.
The two awards
In Idaho's Elmore County, Fervo will use its allocation to drill and complete EGS wells in partnership with multiple national laboratories. The company will also test new high-temperature geophone technology, which it says could extend EGS viability into hotter and more geologically demanding conditions. Advancing subsurface sensing at extreme temperatures is a recognised engineering bottleneck for the technology.
In Nevada's Humboldt County, the grant will fund a targeted appraisal campaign at what the company describes as a high-priority EGS prospect. The aim is to confirm the reservoir's suitability before committing to full development. Fervo's existing commercial EGS pilot, Project Red, has been supplying 3 MW of gross power to the Nevada grid since 2023. The new Humboldt County site would sit outside that footprint.
Chief technology officer Jack Norbeck said the awards signal that "expanding geothermal energy to new states is a national priority" for the federal government and that the funding would accelerate Fervo's project pipeline. Chief executive Tim Latimer framed the grants as a model of public-private partnership for scaling critical energy technologies.
Market and policy context
EGS is the primary frontier for geothermal's expansion beyond the western US resource belt. The DOE's Earthshot initiative targets a tenfold reduction in the cost of enhanced geothermal to $45 per MWh by 2035, and this award sits within a broader federal programme that includes EGS pilot demonstrations and ARPA-E research grants. Fervo has previously received DOE support for its Cape Station flagship development in Milford, Utah.
The commercial case for firm clean baseload is strengthening as grid operators grapple with the intermittency of large solar and wind deployments, and as hyperscale data-centre operators seek power-purchase agreements (PPAs) that guarantee round-the-clock supply. Fervo has publicly positioned geothermal as a candidate for that hyperscaler demand, placing it in competition with long-duration energy storage (LDES), nuclear, and gas with carbon capture for the firm-power contract market.
Federal grant funding remains a key de-risking tool for EGS at this stage of the technology's development. The Inflation Reduction Act's production and investment tax credits apply to geothermal generation, giving commercial projects an incentive layer on top of project-specific DOE support. Any change to those incentive regimes would affect the economics of Fervo's commercial pipeline beyond the grant-funded appraisal work announced today.
The company did not disclose a timeline for final investment decisions on either site, a capacity target for the Humboldt County prospect, or details of any offtake arrangements tied to the new projects. Investors will watch for reservoir confirmation results from Nevada and drilling data from Idaho as the near-term indicators of whether either site can progress to a commercial development decision.
