Eavor Demobilizes Rigs from Geretsried: What It Really Means for Closed-Loop Geothermal For three years, two drilling rigs on a farm estate near Geretsried, a Bavarian town about 40 km south of Munich, stood as the symbol of the world's most ambitious closed-loop geothermal experiment. Now in October 2026, Eavor Technologies, the Calgary-based developer of the Eavor-Loop, has told the town and its heating utility that both rigs would leave the site . The company said keeping idle rigs and specialist services on site was costly, and that releasing them would help put the project in the strongest position to continue with Loop 2 once its commercial structure is reworked . On the surface, this is a logistics decision. Underneath, it is one of the clearest signals yet about where first-of-a-kind geothermal technology stands, and how hard it is to turn a technical proof into a bankable business. This article explains exactly what happened, what the move means and what it does not mean...
Geothermal Financing in the Netherlands: Targeted Investment Strategies with Invest-NL, EBN, and Geothermie Nederland for Low-Carbon Heat Growth
Financing Geothermal Energy: How Targeted Instruments Can Unlock a National Heat Transition
The Netherlands sits on a valuable but underused subsurface resource, sustainable geothermal heat. Ambitious heating targets and growing demand for low-carbon district heat make geothermal an essential part of the energy transition. Yet a familiar barrier persists , high upfront development costs and early,phase risks make many projects unattractive to private financiers. This article explains practical financing instruments, project structures, and policy actions that can reduce those early risks, speed deployment, and attract private capital for geothermal energy at scale.
Why geothermal financing is difficult
Geothermal projects face a financial profile unlike typical renewables. Main challenges include:
, High upfront capital expenditure (CAPEX) during exploration and drilling, with the bulk of costs front,loaded.
, Subsurface uncertainty, resource quality (temperature, flow) is only confirmed after costly drilling.
, Long development timelines and complex permitting processes that inflate perceived risk.
, Integration and offtake risk, connecting to heat networks requires coordination across multiple stakeholders.
, Fragmented project pipelines that prevent risk,pooling and limit opportunities for economies of scale.
These factors combine to create a “valley of death” in the early phases, projects reach drilling or demonstration stages but stall because private finance demands greater certainty than available.
Four targeted financing instruments that reduce early,stage risk
A coherent package of financial instruments can make early,stage geothermal projects bankable sooner. Consider four complementary tools:
, Partial drilling CAPEX subsidy
, What it does, Covers a portion of the drilling and realization costs to lower the initial capital barrier.
, Effect, Reduces the amount of private equity or debt required up front, making smaller or riskier fields feasible.
, Best use, Early pilot wells, high,risk plays, and projects in newly explored basins.
, Development loan facility or heat,source guarantee
, What it does, Provides contingent loans or guarantees specifically for the geothermal source development (exploration and drilling).
, Effect, Lowers cost of capital and encourages commercial lenders to step in earlier in project timelines.
, Best use, Projects that have reasonable geological data but still face financing gaps between exploration and construction.
, Targeted geological,risk reduction (play,opener financing)
, What it does, Invests in subsurface data gathering and targeted drilling in promising but under,explored areas to reduce uncertainty across multiple potential projects.
, Effect, De,risks entire regions (the “play”) so subsequent projects benefit from shared knowledge and lower perceived geological risk.
, Best use, Frontier basins and urban or industrial zones with strategic heating needs.
, Project bundling and a green development vehicle
, What it does, Aggregates multiple small,to,medium geothermal projects into a portfolio for financing, spreading the development risk among many assets.
, Effect, Creates investable scale, attracts institutional capital, and smooths cash,flow profiles.
, Best use, Mature markets with many small projects or developer pipelines where single projects are too small for institutional investors.
Combining two or more of these instruments amplifies impact, for example, partial drilling subsidies plus a development loan facility reduce both the cash barrier and the financing cost, while play,opener investments raise the success rate of drilled wells across a region.
How these instruments change investor behavior
Well,designed instruments alter the risk,return calculus that banks, debt funds, and institutional investors use:
, Lowered upfront capital needs and matched financing reduce credit exposure and increase ability to structure debt.
, Guarantees and targeted public financing shorten time,to,bankability, allowing private investors to earn returns earlier.
, Portfolio approaches appeal to institutional investors who prefer predictable, diversified exposures rather than single high,risk bets.
, Improved subsurface data and shared geological knowledge reduce the perceived “black box” nature of geothermal, making it more comparable to other mature clean technologies.
These changes expand the pool of potential financiers to include pension funds, insurance companies, and green infrastructure funds that demand stable long,term returns.
Supporting measures beyond finance
Finance alone won’t scale geothermal, several complementary actions are essential:
, Better subsurface data collection and public sharing
, A richer public dataset reduces duplication, lowers exploration costs, and enables more accurate resource assessment before drilling.
, Clear, predictable permitting and regulatory timelines
, Certainty on permits reduces schedule risk and avoids unexpected cost escalations.
, Stronger coordination across the heat chain
, Aligning developers, heat network operators, local authorities, and off,takers de,risks realization and accelerates offtake agreements.
, Standardized contracting and technical standards
, Common templates for heat purchase agreements, drilling contracts, and interconnection reduce transaction costs and speed negotiations.
, Capacity building and local ecosystem development
, Strengthening supply chains, local drilling and engineering capabilities, and project development skills reduces costs and improves delivery timelines.
Together, these measures create an environment where financial instruments have their intended leverage.
Practical pathway, phased support linked to project milestones
A milestone,based approach ties public support to technical progress and reduces moral hazard:
1, Exploration grant or play,opener funding
, Purpose, Fund regional surveys, seismic campaigns, and pilot wells to identify promising plays.
, Result, Better early,stage data and a cluster of de,risked sites.
2, Partial drilling CAPEX subsidy (conditional)
, Purpose, Share the cost of the first wells in a project, linked to geological success metrics.
, Result, Lowers developers’ capital needs and signals public commitment.
3, Development loan , heat,source guarantee
, Purpose, Provide contingent financing or guarantees when data shows the resource is viable but commercial finance would still be expensive.
, Result, Private lenders can deploy capital with reduced risk premiums.
4, Realization and scaling support (bundling)
, Purpose, Aggregate projects for institutional financing and offer performance,linked incentives for realization.
, Result, Projects move from demonstration to bankable portfolios attractive to large investors.
This staged approach concentrates public funds where they have the greatest de, risking effect, and it enables private capital to scale up from later stages.
Case for pooling and aggregation
Many geothermal projects are small relative to institutional investment thresholds. Aggregation improves investment metrics:
, Diversifies geological risk, A failure in one well becomes less damaging when combined with successful wells elsewhere.
, Improves size, Larger aggregated financing structures create investment,grade instruments.
, Standardizes returns, Portfolios generate smoother cash flows, matching pension and insurance liabilities.
Public or public,private vehicles can seed aggregation, offering initial capital and structuring expertise, then gradually hand projects over to the private sector.
Maximizing social and local benefits
Well,designed geothermal deployment supports broader social goals:
, Local jobs, Drilling, construction, and operations create skilled employment opportunities.
, Reduced local emissions, District heat and industrial heat substitution reduce fossil fuel use and air pollution.
, Energy security, Domestic heat resources decrease dependency on imported fuels.
, Long,term stable heat prices, Predictable operating costs offer protection against volatile fossil fuel markets.
Policy design should prioritize local procurement, workforce retraining, and community engagement to maximize these co,benefits.
Common design pitfalls to avoid
Policymakers and program designers should watch for these mistakes:
, One,size,fits,all subsidies, Blanket subsidies can misallocate funds to low,potential sites, targeted, conditional support performs better.
, Short,term political cycles, Programs need multi,year stability to attract long,term institutional capital.
, Poor coordination with heat networks, Financing wells without a clear offtake or network plan leads to stranded assets.
, Insufficient data transparency, Keeping subsurface information siloed preserves uncertainty and raises costs for all players.
Avoiding these pitfalls increases the likelihood that public funds catalyze durable private investment.
What investors and developers should prepare
To take advantage of new financing instruments, project teams should:
, Invest in high,quality geological and engineering data from the start.
, Engage early with heat network operators and offtakers to secure conditional offtake agreements.
, Design modular projects that can join bundled portfolios.
, Structure transparent and auditable financials aligned with milestone,based public instruments.
, Demonstrate strong project governance and risk management to attract institutional partners.
Investors should demand standardized reporting, technical due diligence, and clear covenants tied to geological and operational milestones.
A roadmap for the next five years
A pragmatic national roadmap to scale geothermal could include:
, Years 1–2, Launch targeted play,opener programs and improved subsurface mapping, set up a small development loan,guarantee facility.
, Years 2–4, Roll out conditional drilling CAPEX support for demonstration wells and pilot clusters, begin bundling early projects.
, Years 3–5, Scale aggregation vehicles for institutional investment, streamline permitting and standardize contracting.
, Ongoing, Strengthen heat chain coordination, workforce development, and supply chains.
This timeline balances rapid de, risking with prudent use of public funds, enabling private capital to increase participation year,on,year.
Conclusion, targeted finance unlocks large,scale geothermal
Geothermal energy has the technical potential to provide stable, low,carbon heat at scale, but financial and early,stage geological risks currently slow deployment. A coherent package of measures , conditional drilling subsidies, development loan or guarantee facilities, play,opener investments in subsurface data, and project bundling , can substantially lower those barriers. When combined with better data sharing, predictable permitting, and coordinated heat network planning, these instruments make geothermal projects financeable sooner and attractive to a much broader set of investors.
For investors and policymakers focused on delivering secure, low,carbon heat, the message is clear, targeted financial instruments, carefully sequenced and linked to technical milestones, are the most efficient way to convert geological potential into operational heat infrastructure.
