DOE launches $300,000 GEMS Prize to map hidden geothermal systems using algorithm development

On September 10, 2026, the U.S. Department of Energy announced a $300,000 prize competition aimed at one of geothermal energy’s oldest headaches: finding underground resources that leave no trace on the surface. The Geologic Enhanced Mapping System (GEMS) Prize, run by DOE’s Geothermal Technologies Office, asks individuals and teams to build algorithms that use geophysical data to detect faults and subsurface structures tied to hidden geothermal systems. You have until December 3, 2026 to submit.

DOE announces $300,000 GEMS prize for geothermal mapping

The Geothermal Technologies Office (GTO) is running this across two rounds is running this across two rounds, with individual prizes ranging from $15,000 to $100,000. Solo competitors and teams can both enter. The competition lives on a dedicated website, and that December 3 deadline gives you roughly three months to build and submit your work.

The prize goes straight at one of geothermal’s most stubborn problems: you can’t reliably find viable resources without committing to expensive drilling first. By incentivizing algorithm development, DOE is essentially crowdsourcing a technical fix that standard exploration methods haven’t cracked.

DOE Acting Assistant Secretary Curt Coccodrilli pointed to a range of potential benefits in the announcement, citing grid stability, reduced utility costs for U.S.

Why hidden geothermal systems are difficult to detect

Most people picture geothermal energy as geysers, hot springs, or steam vents punching through the earth’s surface — visible features that make identification straightforward. Hidden geothermal systems have none of that. No surface expression means no obvious starting point and no easy shortcut.

What explorers look for instead are subsurface faults and geological structures — underground pathways and heat traps that suggest a viable resource might be sitting below. Pinpointing those features accurately, without drilling, is genuinely hard.

Current exploration methods carry real cost and risk. A test well can run into millions of dollars with no guarantee the resource is commercially usable, and that financial exposure has historically kept private-sector interest low even in regions with solid potential. Geophysical data — seismic measurements, gravity surveys — can reveal subsurface clues when analyzed correctly. Building tools that interpret that data reliably and at scale is exactly the gap GEMS is designed to close.

What competitors must build and how the prize works

You’re not just submitting a concept. The GEMS Prize requires competitors to actually develop, train, and test algorithms capable of generating enhanced geologic fault datasets — a concrete technical deliverable, not a proposal.

Those algorithms get evaluated against real-world geophysical datasets, meaning the testing conditions reflect actual exploration challenges rather than simplified or simulated ones. That distinction matters. It pushes competitors toward practical, deployable solutions instead of theoretical models that don’t hold up in the field.

The two-round structure lets DOE assess progress and reward strong early submissions before naming a final winner. Meaningful incentive is spread across the field — not concentrated entirely on whoever finishes first. The datasets produced through the competition aren’t just a side effect, either. DOE says the resulting fault datasets are intended to support broader geothermal and critical mineral resource mapping, extending the value of this competition well past the prize money itself.

Expected effects on geothermal energy development

GTO says the GEMS Prize should accelerate discovery of commercially viable geothermal systems. Better mapping tools let exploration teams target drilling more precisely, cutting the chance of expensive dry holes and lowering the overall cost of bringing a resource online.

That drop in exploration risk could shift the economics for private investors in a meaningful way. Geothermal has long struggled to attract the same capital as solar or wind, partly because upfront uncertainty runs so much higher. Tools that reduce that uncertainty make the investment case easier to build.

Geothermal carries a fundamental advantage that solar and wind don’t: it’s dispatchable and available around the clock, regardless of weather or time of day. That makes it a baseload resource — one that runs continuously and supports grid stability in ways intermittent renewables can’t match.

DOE Acting Assistant Secretary Curt Coccodrilli pointed to a range of potential benefits in the announcement, citing grid stability, reduced utility costs for U.S. households, domestic manufacturing, and electricity demand from AI data centers as areas where reliable geothermal power could make a real difference.

Policy background and federal geothermal priorities

The GEMS Prize doesn’t exist in a vacuum. GTO frames it explicitly as part of delivering on President Trump’s Executive Order on Unleashing American Energy, which directs federal agencies to advance domestic energy production across fuel types — geothermal included.

GTO sits within Department of Energy and oversees both hydrocarbon and geothermal resource development, an unusual pairing that reflects a focus on subsurface energy broadly rather than any single technology. That institutional positioning signals geothermal is being treated as a serious domestic priority alongside oil and gas — not as an afterthought.

Historically, geothermal has received far less federal investment than solar or wind despite its baseload potential. The GEMS Prize is part of a broader push to change that by reducing the technical barriers that have kept geothermal exploration expensive and uncertain. It fits into a wider federal effort to advance domestic energy production and reduce reliance on imports — a policy direction that increasingly treats geothermal as a real piece of the puzzle.

Prizes range from $15,000 to $100,000

The GEMS Prize offers $300,000 in total awards for algorithm development targeting hidden geothermal systems. Submissions are due December 3, 2026, and both individuals and teams can compete. Prizes range from $15,000 to $100,000 across two rounds. The competition uses real-world geophysical datasets and is designed to produce fault mapping tools that reduce exploration risk and support broader geothermal and critical mineral resource development across the United States.
