Introduction
The next phase of global geothermal development will be shaped not only by geology and technology, but increasingly by national energy policy. Governments are now treating geothermal as more than a niche source of heat or power. They are beginning to see it as a practical option for firm low-carbon electricity, district heating, industrial heat, and energy security.
That shift matters because geothermal projects are unusually sensitive to policy design. Exploration is capital intensive, drilling is expensive, subsurface risk is real, and project timelines can stretch over years before revenue begins. In other words, geothermal is not just an engineering challenge. It is also a finance, regulation, and infrastructure challenge.
Looking toward 2027, five countries offer a useful benchmark for where geothermal policy may be heading: the United States, the United Kingdom, Norway, Canada, and France. Each country is approaching the sector from a different angle. The United States is prioritising commercial scale and technology development. The United Kingdom is building a heat-network market with a stronger regulatory framework. Canada is creating its first national deep-geothermal roadmap. Norway is changing heating policy in a way that may widen the role of low-carbon heat. France already has a mature policy environment that supports geothermal heating, risk management, and investment.
The International Energy Agency has repeatedly argued that geothermal can play a larger role in clean energy systems if governments improve risk mitigation, permitting, data access, market certainty, workforce development, and research support. That broad policy message is becoming more visible in national frameworks. As 2027 approaches, geothermal is moving from a technical possibility to a policy-backed investment theme.
United States
The United States enters the 2027 policy period with geothermal positioned inside a broader push for domestic clean energy, technology innovation, and reliable power. The U.S. Department of Energy’s FY2027 budget materials continue to support geothermal research and development, while also pointing toward commercial scale deployment and the acceleration of gigawatt-scale geothermal energy. This matters because the country has both the geological diversity and the industrial base to become a major geothermal market if technology and policy line up.
The most important feature of the U.S. market is that it is no longer limited to conventional hydrothermal resources. Advanced geothermal systems, including enhanced geothermal systems, could make geothermal viable in many more locations. That expands the market far beyond the historic geothermal regions of the western United States. It also links the sector more closely with drilling, completion, reservoir modelling, and subsurface engineering capabilities that already exist in the oil and gas supply chain. The IEA has also highlighted next-generation geothermal as a major innovation area with growing investment momentum.
For 2027, several policy areas are likely to remain central in the United States. These include exploration and resource characterisation, high-temperature drilling, commercial demonstration projects, and grid integration. The big question is whether the country can move from repeated demonstrations to bankable, repeatable project delivery. If that happens, the United States could set the global reference point for next-generation geothermal economics.
The wider significance is international. Techniques proven in the United States would not stay there. Drilling practices, reservoir stimulation methods, and project-development models could be transferred to markets in Europe, North America, the Middle East, and parts of Asia. In that sense, U.S. geothermal policy is not just a domestic energy issue. It is a global technology signal.
United Kingdom
The United Kingdom offers a very different geothermal pathway. Its near-term opportunity is linked more strongly to heat than to large-scale electricity generation. That is important because the UK has a dense urban heating market, a growing policy focus on decarbonising homes and buildings, and a new regulatory structure for heat networks. Geothermal fits naturally into that picture as a source of low-carbon base heat.
The government’s Warm Homes Plan aims to raise the share of heat demand supplied by heat networks in England to 7% by 2035, equivalent to 27 TWh, with heat networks expected to provide around one-fifth of heat by 2050. The state is also supporting investment through the Green Heat Network Fund. For geothermal developers, that is an important market signal because heat networks create a ready-made route to monetise underground heat.
The regulatory shift is equally important. Ofgem became the regulator for heat networks in Great Britain in January 2026, and operators must register under the new framework, with key deadlines running into January 2027. The Heat Network Technical Assurance Scheme is also expected to begin in 2027. That means geothermal projects will need to perform not only geologically, but also as regulated utility assets.
This creates both opportunity and discipline. Geothermal heating projects can benefit from the growing policy preference for lower-carbon heat, but they will also need to meet consumer protection, reliability, billing, and technical assurance requirements. In practice, that could favour developers with strong engineering, operating, and finance capability rather than those focused only on subsurface discovery.
Norway
Norway is a more complex case. It has exceptional drilling, offshore engineering, and subsurface expertise, yet geothermal is not currently a central pillar of its energy policy. Still, that does not mean geothermal is irrelevant. In a country already deeply concerned with building emissions, energy system balance, and industrial decarbonisation, low-carbon heat technologies can still find room to grow.
A key policy development came in June 2026, when the Norwegian government proposed a ban on fossil gas for permanent heating of buildings from January 1, 2028. The proposal covers homes, commercial buildings, and agricultural buildings. The government framed the move as part of Norway’s wider climate goals, and the consultation process was opened in 2026. Even if fossil gas is only a small part of Norway’s heating mix, the policy still matters because it pushes the heating system further toward non-fossil options.
Geothermal may not become a mass-market Norwegian heating solution overnight. However, policies that reduce fossil fuel use in heating tend to open space for alternative low-carbon sources. That could include geothermal in specific urban, industrial, or district-heating settings, especially where integrated thermal systems make sense. Norway’s ongoing work on surplus heat regulation also matters because future thermal networks may combine geothermal heat, waste heat, and storage in the same system.
The broader lesson is that geothermal does not always need to be the headline policy issue to benefit from policy change. Sometimes it grows in the spaces created when governments tighten heating rules and look for reliable low-carbon substitutes.
Canada
Canada is entering a particularly important phase because it is building a national framework before geothermal deployment scales up. In June 2026, Natural Resources Canada announced funding for the country’s first national deep-geothermal roadmap. The project is being led by the Canadian Deep Geothermal Coalition with support from the Cascade Institute, and it is designed to identify technology opportunities and research priorities for next-generation geothermal development.
That is a meaningful step because Canada has many of the ingredients geothermal needs, including drilling expertise, subsurface engineering capability, and a growing interest in clean, dispatchable energy. What it has lacked is a coordinated national roadmap that links resources, technology, regulation, and investment. The new project could help bridge that gap by bringing together industry, researchers, Indigenous partners, and governments.
For 2027, Canada’s geothermal agenda will likely revolve around deep geothermal resources, next-generation systems, drilling technology, research and development, and the role of Indigenous participation in project design and implementation. The country also has an opportunity to connect geothermal with district heating, industrial heat, and clean electricity in regions where power systems are under decarbonisation pressure.
The broader significance of the roadmap is that it reduces ambiguity. Investors generally hesitate when geological risk, market structure, and policy support are unclear. A national roadmap does not eliminate those risks, but it can make the sector more legible. That can help move geothermal from a promising concept to a structured investment category.
France
France remains one of the strongest European examples of a country with a mature geothermal policy framework. It already treats geothermal as a useful tool for heating, cooling, electricity, and energy independence. More importantly, it has developed support mechanisms that address the practical barriers to deployment, including investment aid, geothermal guarantees, research support, and regulatory tools. The IEA and French policy developments both reinforce the importance of support for next-generation geothermal and heat use.
France’s strength lies in the way it connects geothermal resources with heat demand. District heating and building heat are central parts of the market. That matters because geothermal can deliver value without first being converted into electricity. In places where there is concentrated heat demand, direct use is often the most efficient pathway. France has long understood that logic, and its policy framework reflects it.
Recent policy changes have also shown a willingness to simplify deployment. In 2026, France broadened the scope of shallow and low-enthalpy geothermal projects that do not require declaration or authorisation under the mining code. It also expanded the threshold for certain low-enthalpy projects under the geothermal regime of minimal importance. These steps are designed to reduce friction for smaller projects while keeping a regulatory structure for higher-risk developments.
France also places strong emphasis on geological risk and environmental management. Deep geothermal can involve upfront drilling costs before a resource is fully proven, so risk-mitigation mechanisms matter. The country has also developed technical guidance around induced seismicity, reinforcing the idea that geothermal expansion must remain compatible with environmental safeguards and public confidence. That balance is one of France’s most important lessons for other markets.
Shared Policy Themes
Although these five countries are moving in different directions, several common themes stand out. The first is geological risk. Geothermal developers still face uncertainty before drilling confirms temperature, permeability, and flow. That means governments that want geothermal growth usually need some kind of risk-sharing or risk-reduction mechanism.
The second is drilling cost. Drilling remains one of the biggest barriers to geothermal scale-up, especially for deeper and hotter resources. Any policy that improves drilling performance, lowers well costs, or speeds up project delivery can have an outsized effect on project economics. This is why expertise from oil and gas is becoming so relevant to geothermal development.
The third is heat networks. The United Kingdom and France show how geothermal can become valuable when it is tied to urban heating infrastructure. That model is different from a pure electricity strategy, but it may be just as important for emissions reduction. It also broadens the customer base beyond power buyers to building owners, utilities, and municipal systems.
The fourth is advanced geothermal technology. Enhanced geothermal systems, superhot rock concepts, and improved reservoir engineering could dramatically widen the global resource base. The IEA has increasingly highlighted next-generation geothermal as a serious innovation area, not a speculative side story. That makes 2027 a potentially important year for the transition from pilot projects to a more credible commercial pipeline.
Investment Outlook
From an investment perspective, geothermal is becoming less about installed megawatts alone and more about the structure of the revenue stack. In some markets, that means electricity sales. In others, it means district heating, industrial heat, cooling, thermal storage, or even data-centre energy supply. In still others, it may involve using existing oil and gas infrastructure in new ways.
This matters because geothermal economics depend on matching the subsurface resource to the right market. A project with excellent heat quality may be stronger as a district-heating asset than as a power plant. A deep, high-temperature system might be more attractive for electricity or industrial use. The policy environment has to leave room for those different business models.
Looking toward 2027, investors are likely to pay closer attention to countries that offer a combination of clear policy direction, manageable permitting, available infrastructure, and predictable revenue. In that respect, the United States, United Kingdom, Canada, France, and Norway each offer different kinds of opportunity. The best market will depend on whether the investor is focused on power, heat, technology, or infrastructure.
What 2027 Could Bring
By 2027, geothermal policy may look less like a collection of separate national initiatives and more like a global pattern. Governments are likely to keep pushing for lower-carbon heating, cleaner power, and better energy security. Geothermal fits all three goals, but only when the policy framework supports the realities of drilling, exploration, and long project lead times.
The likely direction is clear. The United States will keep pushing technology and commercialisation. The United Kingdom will keep tightening the rules and expanding the heat-network market. Canada will keep building a national strategy from the ground up. France will continue strengthening a mature model built around heating and risk management. Norway may create new indirect opportunities through heating policy and system integration.
The broader message is that geothermal is becoming an investment issue as much as an energy issue. The countries that succeed will be those that connect resource potential with finance, regulation, infrastructure, and customers. That is the real test for 2027.
Conclusion
The global geothermal industry is entering a more mature policy phase. The central question is no longer whether geothermal has potential, but whether countries can build the regulatory, financial, and technical systems needed to unlock it.
The United States is leaning into advanced technology and commercial deployment. The United Kingdom is building a regulated heat-network market. Canada is creating a national roadmap for deep geothermal. France is refining a policy environment that already supports geothermal heating and risk management. Norway is reshaping its heating policy in ways that may create room for more low-carbon thermal solutions.
Together, these markets show that geothermal policy can take many forms. It can be a power policy, a heat policy, a technology policy, or a decarbonisation policy. What matters is that the system around the resource works.
As 2027 approaches, the countries that align geology, technology, finance, infrastructure, and regulation will define the next stage of geothermal growth. The lesson for the global industry is simple. The heat underground matters, but the policy above it may matter just as much.
