Geothermal Is the Only Clean Energy Getting More Federal Money. Here's Where the $200 Million Is Going.

The Department of Energy's clean energy portfolio is being dismantled in slow motion. Solar and wind tax credits are being phased out under the One Big Beautiful Bill Act. The hydrogen program lost billions. EERE's budget faces a proposed 65 percent cut in the FY2027 request. And yet, buried in the wreckage, one technology is not only surviving — it's getting the biggest federal investment in its history.

Geothermal energy just received over $200 million in new DOE funding across two programs. The Office of Geothermal announced $171.5 million for next-generation field tests and exploration drilling. ARPA-E committed $30 million to its SUPERHOT program for superhot rock geothermal R&D. Combined with a 15-state Geothermal Power Accelerator launched in January 2026 and eight bipartisan permitting reform bills advancing through the House Natural Resources Committee — six with unanimous support — geothermal is experiencing a federal policy moment that no other clean energy technology can claim right now.

If you work in geothermal energy, enhanced geothermal systems, deep drilling technology, subsurface engineering, or adjacent fields like oil and gas reservoir characterization, this is your window.

$171.5 Million for Field-Scale Geothermal Demonstrations

On February 25, 2026, DOE's Office of Geothermal announced what amounts to the largest competitive geothermal funding opportunity in the agency's history. The $171.5 million Notice of Funding Opportunity targets two priorities in its first round: Enhanced Geothermal Systems (EGS) field tests and drilling for next-generation and hydrothermal resource characterization and confirmation.

The framing matters. DOE is explicitly prioritizing "real-world demonstrations and subsurface validation work that reduce uncertainty and accelerate bankable geothermal development." This is not bench-scale research money. The agency wants field-scale tests at depths and temperatures appropriate for full-scale project development — the kind of work that derisk projects enough for private capital to follow.

The NOFO describes six topic areas total, with two open in this first round and additional topics expected in future rounds. Letters of Intent were due March 27, and full applications closed April 30. But applicants should watch for future topic areas, which will open additional funding tranches.

Kyle Haustveit, DOE Assistant Secretary for the Hydrocarbons and Geothermal Energy Office, tied the funding directly to the administration's energy agenda: "Work under this opportunity will directly support commitments to advance energy addition and unleash American energy dominance."

That language is deliberate. Geothermal has been rebranded within the administration not as "clean energy" but as "baseload, dispatchable, American-made power" — a framing that insulates it from the political headwinds battering solar and wind.

ARPA-E SUPERHOT: $30 Million to Crack the Deepest Reservoirs

While the Office of Geothermal focuses on near-commercial demonstrations, ARPA-E's SUPERHOT program is pushing the frontier. The $30 million program targets technologies that can produce geothermal energy from reservoirs exceeding 375°C and 22 MPa — conditions that exist deep beneath much of the continental United States but that current drilling and materials technology cannot reliably access.

SUPERHOT funds two categories of work. Category 1 focuses on well construction: developing materials and designs that can survive supercritical conditions for 15 or more years, along with testing facilities to validate those designs before they go into the ground. Category 2 targets heat extraction: novel methods for moving thermal energy from superhot reservoirs into working fluids, including approaches that do not rely on conventional fracture stimulation.

The technical bar is deliberately high. The program is not funding incremental improvements to existing geothermal wells. It is funding the technologies that would make entirely new classes of geothermal resources accessible — the kind that could transform geothermal from a niche player (currently about 4 GW of U.S. capacity) into a major contributor to the grid.

DOE analysis suggests enhanced geothermal could reach 300 GW of capacity by 2050 — roughly 75 times today's installed base. Getting there requires drilling deeper, hotter, and cheaper than anyone has managed commercially. SUPERHOT is the program betting on the technologies that make that possible.

Why Geothermal Survived the Clean Energy Purge

Understanding the current policy landscape is essential for anyone positioning a proposal in this space. The One Big Beautiful Bill Act, signed in July 2025, phased out production and investment tax credits for solar and wind energy. But it largely preserved tax incentives for commercially leased geothermal heat pumps and thermal energy storage systems. The contrast is stark and deliberate.

Geothermal fits the administration's energy narrative in ways that other renewables do not. It provides firm, dispatchable baseload power — the kind the grid needs for data centers, industrial facilities, and military installations. It shares drilling technology and workforce with the oil and gas industry, making it politically palatable in fossil fuel states. It requires no intermittency solutions, no battery storage, no grid integration complexity. And critically, geothermal resources are entirely domestic, fitting the "energy dominance" framework that drives current DOE priorities.

This political alignment extends to Congress. On March 5, 2026, the House Natural Resources Committee favorably reported eight geothermal bills, with six receiving unanimous bipartisan support. The legislation addresses the single biggest barrier to geothermal development: permitting. Key bills include H.R. 301, which requires permits within 60 days after environmental review completion; H.R. 1077, which extends NEPA categorical exclusions from oil and gas to geothermal projects; and H.R. 5631, which establishes a dedicated ombudsman for dispute resolution.

These are not symbolic gestures. BLM permitting for geothermal projects on federal lands has historically required seven to ten years. If the permitting reforms pass, they would fundamentally change the economics of geothermal development on federal lands — which is where much of the best geothermal resource sits.

State-Level Action Is Accelerating Too

Federal money is only part of the picture. Multiple states are moving independently to create favorable regulatory environments for geothermal development:

The 15-state Geothermal Power Accelerator, launched in January 2026, is coordinating much of this activity, creating a pipeline of state-level regulatory readiness that federal funding can flow into.

The Funding Gap Is Still Enormous

Despite the favorable policy environment, experts caution that $200 million is a fraction of what geothermal actually needs to scale. Terra Rogers of the Clean Air Task Force put it bluntly: "The signal is strong, but the dollars are still a blip in terms of what we need." For context, DOE allocated over $9 billion for hydrogen and $10 billion for nuclear under the previous administration's Bipartisan Infrastructure Law.

Geothermal's current investment landscape relies heavily on venture capital, wealthy individuals, and family offices. Fervo Energy's $462 million Series E round — backed by Google, Liberty Mutual Investments, and traditional VCs — demonstrated that private capital is interested, but the industry needs broader participation from corporate venture capitalists, investment banks, and off-taker customers to reach the scale the resource potential demands.

This is precisely why the federal funding matters disproportionately. At this stage of the industry's development, DOE dollars serve less as direct project financing and more as risk reduction that unlocks multiples of private capital. A successful EGS field test funded by the $171.5 million NOFO does not just advance one project — it generates the performance data that makes the next hundred projects financeable.

Who Should Be Paying Attention

The applicant pool for these opportunities is broader than traditional geothermal companies. DOE's guidance for the $171.5 million NOFO emphasizes multiparty teaming arrangements spanning developers, drillers, engineers, and equipment manufacturers. Prime applicants need site control, realistic permitting plans, and early engagement with subcontractors.

For oil and gas companies and service providers, the translation is direct. The drilling expertise, subsurface characterization capabilities, and project management infrastructure that define the petroleum industry are exactly what geothermal development needs. Several of the permitting reform bills explicitly leverage this connection by extending oil and gas NEPA categorical exclusions to geothermal.

For university researchers, ARPA-E's SUPERHOT program is the entry point. The materials science, reservoir engineering, and drilling technology challenges are fundamental research problems with clear pathways to commercialization. ARPA-E's IGNIITE 2026 program, with concept papers due May 28, also funds early-career energy innovators — a potential pathway for geothermal researchers who do not yet have the track record for larger ARPA-E programs.

For small businesses, the DOE Office of Geothermal is not the only game. DOE's SBIR program regularly includes geothermal-relevant topics, and ARPA-E's rolling OPEN solicitation accepts geothermal proposals year-round.

The convergence of federal funding, bipartisan permitting reform, state regulatory action, and administration alignment makes this the strongest policy environment for geothermal energy in American history. The money is real, the politics are favorable, and the technical challenges are the kind that attract precisely the interdisciplinary teams that win competitive federal awards.
