Geothermal Startups Seek Federal Backing Amid Energy Push

Congress is weighing a package of federal subsidies and loan guarantees for geothermal energy developers as the sector confronts drilling costs that can reach tens of millions of dollars per well, threatening to stall one of the most promising zero-carbon baseload technologies in the clean energy portfolio. Lawmakers on both sides of the aisle have signalled cautious support for expanded backing, though disagreements over the scale and structure of any federal intervention remain unresolved, according to congressional aides and industry representatives.

The Case for Geothermal at a Federal Level

Geothermal power — which harvests heat from the earth's crust to generate continuous, weather-independent electricity — has attracted renewed political attention as grid operators warn that intermittent solar and wind capacity alone cannot guarantee reliability. Unlike photovoltaic or wind installations, geothermal plants generate electricity around the clock, making them a rare renewable source capable of providing baseload power without battery storage.

The Department of Energy has identified enhanced geothermal systems (EGS), which use hydraulic fracturing-style drilling techniques to access heat in dry rock formations, as a transformative technology that could theoretically supply a significant share of domestic electricity demand. Yet the capital intensity of the drilling phase — which borrows heavily from oil and gas methodology — means that private investors routinely demand risk premiums that push project costs beyond the reach of early-stage developers without federal support.

Enhanced Geothermal Systems: The Technology at Stake

EGS technology injects water into hot subsurface rock, where it absorbs heat before returning to the surface to drive turbines. The process requires precision drilling to depths often exceeding three miles, with well costs comparable to deepwater oil exploration. Several pilot projects currently under development in the western United States are testing whether commercial-scale EGS can be made economically viable, but developers say they need guaranteed loan facilities and production tax credits to bridge the funding gap between laboratory success and utility-scale deployment.

Industry groups have told congressional committees that the risk profile of geothermal drilling is broadly analogous to early-stage offshore oil exploration — high upfront capital, uncertain subsurface conditions, and multi-year lead times before revenue materialises. That comparison has resonated with legislators from oil-producing states, some of whom represent constituents in the drilling services industry who could pivot to geothermal contracts. For context on how traditional energy sectors are managing the broader clean energy pivot, see our coverage of how Texas refineries navigate energy transition challenges.

Legislative Landscape and Congressional Dynamics

A bipartisan group of senators has introduced legislation that would extend the Investment Tax Credit to geothermal projects on a technology-neutral basis, alongside a dedicated loan guarantee programme modelled on existing Department of Energy Title XVII facilities. The bill's sponsors argue that the federal government has historically underinvested in geothermal relative to wind and solar, leaving the technology commercially underdeveloped despite its geological potential.

Opposition and Budget Constraints

Fiscal conservatives have raised objections to expanding the federal loan guarantee portfolio at a time of elevated borrowing costs and persistent deficit pressure. Budget hawks on the House side have questioned whether the government should bear exploration risk that they argue should sit with private capital markets. The debate echoes broader tensions over the pace and financing of the energy transition, which have intensified as interest rate levels remain above pre-pandemic norms. For an analysis of how monetary conditions are affecting business investment broadly, our report on the Bank of England holding rates as inflation cools provides relevant context on the global rate environment shaping capital allocation decisions.

Opponents of the subsidy package also point to the mixed record of previous loan guarantee programmes, arguing that government-backed clean energy lending carries inherent moral hazard. Proponents counter that the historical default rate on DOE energy loans has been lower than critics suggest and that the strategic value of energy security justifies the exposure.

Market Economics and the Cost Challenge

The core economic problem facing geothermal developers is the mismatch between the timing of costs and the timing of revenues. Drilling and site development typically consume the bulk of project capital before a single kilowatt-hour is sold, creating a funding valley that equity investors, absent federal support, are reluctant to cross for an unproven resource.

Bloomberg Intelligence data indicate that the levelised cost of electricity from conventional geothermal plants — where high-temperature resources are accessible at shallower depths — is broadly competitive with other clean energy technologies. However, EGS projects, which represent the scalable frontier of the sector, carry cost estimates that are significantly higher and subject to wide uncertainty depending on local geology, according to Bloomberg analysis of project pipeline data.

Comparison with Fossil Fuel Subsidies

Advocates for geothermal subsidies frequently note that the fossil fuel sector has benefited from preferential tax treatment for decades, including the intangible drilling cost deduction — a provision that allows oil and gas producers to immediately expense a large portion of well development costs. Extending analogous treatment to geothermal drilling, they argue, would simply level a playing field that has long been tilted toward hydrocarbons. The Financial Times has reported that the cumulative value of fossil fuel tax preferences in the United States runs into hundreds of billions of dollars over a decade, a figure that geothermal advocates invoke when characterising their subsidy requests as modest by comparison.

The geopolitical dimensions of energy supply have also sharpened the domestic production argument. Shifts in global oil markets and diplomatic realignments — including the implications explored in our analysis of how an Iran peace deal reshapes U.S. energy import strategy — have underscored the strategic premium placed on domestically sourced energy that is not subject to supply chain disruption.

Winners, Losers, and Sectors Affected

A federal subsidy regime for geothermal would create a clear set of winners and losers across adjacent industries and labour markets.

Potential Beneficiaries

Oilfield services companies stand to gain significantly if EGS drilling activity scales up. The skills and equipment required — rotary drilling rigs, wellbore casing, directional drilling expertise — are directly transferable from oil and gas applications. Workers in fossil fuel extraction, particularly those facing displacement from coal and conventional oil decline, represent a potential labour supply for geothermal development. That workforce transition dynamic mirrors patterns already visible in automotive manufacturing, as detailed in our report on how Detroit's auto plants are remaking the Motor City's factory floor amid the electric vehicle transition. Grid operators and utilities in regions with accessible geothermal resources — principally the western United States — would benefit from a new source of firm, dispatchable power that reduces reliance on natural gas peaker plants.

Industries Facing Headwinds

Natural gas producers and operators of gas-fired generation assets face the most direct competitive pressure from successful geothermal scaling. If EGS proves commercially viable at scale, it could erode the role of gas as the default reliability backstop for variable renewables. Coal plant operators, already under sustained financial and regulatory pressure, would find their remaining market rationale further diminished. For a detailed account of the structural challenges facing the sector, our investigation into America's last coal plants and why the exit is taking so long provides essential context on grid reliability concerns that geothermal proponents argue their technology could address.

International Comparisons and Policy Benchmarks

The United States is not the first country to deploy federal support for geothermal exploration. Iceland has built an entire national energy system around geothermal resources, covering the majority of its heating demand and a substantial share of electricity generation. Kenya, with support from multilateral development banks, has expanded geothermal capacity to account for a significant proportion of its national grid. New Zealand has operated commercial geothermal plants for decades under a regulatory framework that combined private investment with state-backed risk mitigation during the early exploration phase.

The IMF has noted in recent reports that countries with established geothermal sectors typically relied on public risk-sharing mechanisms during the exploration and appraisal phases before transitioning to predominantly private financing once resource characteristics were confirmed. (Source: IMF) That model — government bears exploration risk, private capital finances construction — is broadly what U.S. geothermal advocates are proposing, though the specific terms remain contested in congressional negotiations.

Labour Market and Regional Economic Implications

The ONS has tracked comparable patterns in the United Kingdom's energy sector transition, finding that regions historically dependent on fossil fuel extraction face structural unemployment risks when those industries contract without adequate replacement job creation. (Source: ONS) While the U.S. geothermal buildout would be geographically concentrated in the west and southwest rather than traditional coal country, the broader lesson — that energy transition employment policy requires proactive intervention — is broadly applicable.

Congressional representatives from Nevada, California, Utah, and Idaho have been among the most vocal proponents of geothermal subsidies, reflecting the concentration of accessible geothermal resources in their states. Economic impact assessments submitted to congressional committees have projected thousands of direct and indirect jobs from a sustained geothermal drilling programme, though independent economists have cautioned that such projections carry significant uncertainty and depend heavily on technology cost trajectories.

Outlook: Federal Decision Point Approaches

The legislative window for geothermal provisions is narrowing as congressional attention turns to broader fiscal negotiations. Industry lobbyists have pressed for inclusion of geothermal loan guarantees and production credits in any forthcoming energy or tax legislation, arguing that delay compounds the disadvantage relative to wind and solar, which benefit from a more established federal incentive architecture.

Whether Congress ultimately delivers the scale of support the geothermal sector is seeking will depend on the outcome of negotiations that remain fluid. What is not in dispute is the underlying resource potential: the United States sits atop vast geological heat resources that, if commercially unlocked, could materially alter the country's clean energy profile. The question being resolved in congressional offices and committee rooms is not whether geothermal works as a technology — demonstration projects have settled that question — but whether the federal government is willing to absorb the financial risk required to prove it works at scale.

For a sector that has long operated in the shadow of more politically prominent renewables, the current legislative moment represents an unusual opportunity. Whether developers can convert that attention into durable federal commitment, before the political window closes, may determine the pace of the technology's commercial development for years to come.
