DOE Allots $99M for Geothermal Field Tests
Estimated reading time: 3 minutes · Last updated:
The U.S. Department of Energy announced more than $99 million to support 21 projects that will test and map next‑generation geothermal resources across the United States. Five awards will back field‑scale enhanced geothermal systems (EGS) tests, and 16 will fund exploration drilling to identify and characterise promising sites. The DOE said data from the projects will be made public through the Geothermal Data Repository (GDR). The Department also cautioned that selection begins award negotiations, not an unconditional commitment to pay, and that final funding depends on those negotiations.
“These projects will empower American innovators to unlock the tremendous geothermal resources beneath our feet,”

Key takeaways
- The U.S. Department of Energy announced more than $99 million to advance geothermal projects.
- The awards cover 21 projects in total: five field‑scale EGS tests and 16 exploration drilling efforts.
- Project data will be published in the Geothermal Data Repository (GDR) for industry and researchers to use.
- DOE stresses that selection moves teams into negotiations; it is not a commitment to issue funding.

What the $99 million pays for
The funding splits between two practical activities. Five projects will run field‑scale enhanced geothermal systems tests designed to validate technologies under operational conditions; these tests aim to show whether approaches developed in the lab scale up in the subsurface at commercially relevant sizes. The other 16 awards back exploration drilling to characterise promising next‑generation geothermal resources, delivering site data such as temperature profiles and rock properties that developers need to assess viability.
DOE frames this portfolio as an attempt to reduce technical and development risk by producing real‑world performance data rather than bench or modelling results alone.
Public data to accelerate follow‑on projects
All project outputs will be uploaded to the Geothermal Data Repository (GDR), giving companies, national labs and academic teams access to the same measurements from each site. Shared datasets make it easier to compare methods, replicate results and refine exploration workflows without repeating every costly drill or test.
By centralising information, DOE intends the GDR entries to inform future technology development and help potential commercial projects and investors evaluate resource potentials on a consistent basis.
Next steps, limitations and what this does not do
Selection moves recipients into negotiations with DOE; it is not a promise of funding. DOE says it may cancel negotiations or rescind selections during that process. That procedural caveat limits how quickly awarded teams can spend or commit other capital.
Separately, the programme’s design is diagnostic rather than commercial formation: the grants are meant to lower the technical uncertainty that slows project financing, but they do not themselves constitute private investment or guaranteed development of utility‑scale plants.
| Activity | Number of projects | Primary aim |
|---|---|---|
| EGS field tests | 5 | Validate next‑generation geothermal technologies under field conditions |
| Exploration drilling | 16 | Characterise promising geothermal resources for future development |
| Total | 21 | $99 million in announced funding for all selected projects |
How this can move the sector
The case for
- Published field data from the GDR could standardise resource assessment and speed follow‑on investment decisions.
- Validated EGS methods at scale would expand resource maps beyond conventional hydrothermal sites, increasing potential development areas.
The case against
- If negotiations fail or awards are reduced, projects may be delayed or cancelled and the expected public dataset will be smaller.
- Field tests that underperform could raise perceived technical risk and deter private capital rather than attract it.
What to be careful about
- DOE’s selection is subject to negotiation and may be rescinded, which could halt projects before they begin.
- Field‑scale tests can encounter subsurface issues (low permeability, induced seismicity) that limit technology validation.
- Exploration drilling can fail to find commercially viable temperatures or flow paths, leaving data useful but not leading to development.
The bottom line
DOE’s $99 million announcement is aimed at shifting geothermal work from models and lab tests into field demonstrations and exploration, producing standardised datasets through the GDR. The five EGS field tests and 16 exploration drills should supply the measurements needed to compare methods and reduce technical uncertainty. The programme’s immediate impact will depend on successful negotiations and on the outcomes of individual tests and wells; the public release of project data is the clearest near‑term benefit for industry and researchers.
What to watch
- Watch for DOE to finalise award negotiations and publish the list of confirmed recipients; no date has been set.
- Watch for the first tranche of project data to appear in the Geothermal Data Repository (GDR); no date has been set.
Frequently asked questions
How much money did DOE announce and how many projects will it support?
The U.S. Department of Energy announced more than $99 million to advance 21 projects, split between five field‑scale EGS tests and 16 exploration drilling efforts.
Where will the data from these projects be published?
DOE will make project outputs publicly available through the Geothermal Data Repository (GDR), enabling researchers and industry to access field measurements and drilling results.
Does selection mean teams will definitely receive funding?
No. Selection advances applicants into award negotiations; DOE states selection is not a commitment to issue funding and it may cancel negotiations during the process.
