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 Energy Stocks to Watch in 2026: Top 5 Companies Leading the Revolution
Image : A Thematic Image of an Ormat Power Plant
Geothermal energy is becoming one of the most closely watched areas of the global clean-energy industry. For decades, geothermal power remained a specialized technology concentrated in regions with naturally accessible underground heat. Today, improvements in drilling, reservoir engineering, well construction, digital monitoring, and power-generation technology are creating the possibility of developing geothermal resources in a much broader range of locations.
Investors are paying closer attention because the electricity system is changing rapidly. Demand is rising from data centers, artificial-intelligence infrastructure, electric vehicles, industrial electrification, manufacturing, and population growth. At the same time, utilities and governments are seeking reliable low-carbon electricity that can complement intermittent solar and wind generation. Geothermal power, which can operate continuously when a resource is properly developed, may become an important part of this future energy mix.
However, the geothermal stock market remains relatively small. There are only a limited number of publicly traded companies with direct geothermal exposure. Most listed companies connected to the sector are diversified energy-technology, drilling, or oilfield-services businesses. This means investors must understand the difference between a pure-play geothermal company and a corporation that merely supplies equipment or services to geothermal developers.
This article examines five geothermal energy stocks to watch in 2026: Ormat Technologies, Baker Hughes, SLB, Halliburton, and Helmerich & Payne. Each company participates in the geothermal value chain differently. Ormat provides the most direct exposure through geothermal power generation and equipment, while the other four companies offer indirect exposure through drilling, reservoir engineering, well construction, and energy technology.

Why Geothermal Energy Is Attracting Investors
Geothermal energy uses heat stored beneath the Earth’s surface to produce electricity or provide direct thermal energy. In conventional geothermal development, companies identify underground reservoirs containing naturally occurring heat, water, and permeability. Wells are drilled into the reservoir, hot fluids are brought to the surface, and the heat is used to generate electricity or provide heating before the fluids are reinjected underground.
The technology has several features that make it attractive in a changing electricity market. Geothermal plants can potentially operate day and night, unlike solar power, whose output depends on sunlight, or wind power, whose production varies with weather conditions. This ability to provide firm or dispatchable electricity can make geothermal valuable to utilities and large commercial customers that require consistent power.
Geothermal plants also have a relatively small land footprint compared with some other forms of electricity generation. They do not require fuel deliveries in the same way as coal or gas plants, and their emissions can be relatively low when projects are properly designed and managed. In addition to producing electricity, geothermal resources can support district heating, greenhouse agriculture, industrial processes, aquaculture, and heat-pump applications.
The traditional limitation has been geography. Conventional geothermal projects are usually most attractive in areas with high heat flow, volcanic activity, naturally permeable rock, and accessible underground fluids. This has historically concentrated development in countries such as the United States, Iceland, Indonesia, the Philippines, New Zealand, Kenya, Türkiye, and Italy.
New technologies are changing that assumption. Enhanced geothermal systems, closed-loop geothermal systems, advanced drilling techniques, and improved subsurface modelling may allow companies to access heat in locations that do not have naturally productive reservoirs. If these technologies become commercially successful, the potential market for geothermal power could expand significantly.
The investment opportunity is also connected to the rapid growth of electricity demand. Data centers and artificial-intelligence facilities require large amounts of reliable electricity. Technology companies are increasingly exploring long-term clean-power contracts to meet sustainability goals while maintaining dependable operations. Geothermal energy could compete for this demand alongside nuclear power, hydropower, natural gas with carbon capture, batteries, and other firm-energy technologies.
Despite this potential, geothermal development remains technically challenging and capital intensive. Drilling outcomes can be uncertain, project timelines can be long, and a resource that appears attractive on paper may not produce sufficient temperature, pressure, permeability, or flow rate after drilling. These risks make careful company analysis essential.
Understanding Direct and Indirect Geothermal Exposure
Before researching geothermal stocks, investors should identify the type of exposure each company provides.
A direct geothermal company develops, owns, operates, or manufactures equipment specifically for geothermal power projects. Its revenue and earnings are likely to be influenced by geothermal project construction, electricity generation, resource performance, power-purchase agreements, and geothermal equipment sales. Ormat Technologies is the best-known publicly traded example of this type of business.
An indirect geothermal company supplies drilling rigs, well services, cementing, completion technology, reservoir modelling, turbines, digital systems, or other equipment used by geothermal developers. These companies may benefit from geothermal growth without owning geothermal power plants. Baker Hughes, SLB, Halliburton, and Helmerich & Payne fall primarily into this category.
Indirect exposure can offer some advantages. Diversified companies usually have broader revenue streams and may be less vulnerable to the failure of one geothermal project. They may also benefit from their existing relationships with energy companies and their experience in complex subsurface operations.
The disadvantage is that geothermal may represent only a small portion of their total business. A company can announce a geothermal partnership without that partnership having a material impact on annual earnings. Its share price may remain primarily linked to oil prices, natural-gas activity, industrial demand, global capital spending, or broader market conditions.
Investors should therefore avoid treating all geothermal-related stocks as interchangeable. The correct question is not only whether a company is involved in geothermal energy, but also how significant that involvement is compared with its overall business.
Company Overview
Ormat Technologies is widely regarded as the most direct geothermal investment available to many public-market investors. The company develops, owns, operates, and manages geothermal power plants and also supplies geothermal equipment. Its activities extend across project development, engineering, power generation, and energy infrastructure.
This integrated model gives Ormat a distinctive position in the sector. The company can earn revenue by selling equipment to other developers, but it can also retain ownership of operating assets and generate income from electricity sales. This combination provides exposure to both the construction and operating phases of geothermal projects.
Ormat’s business includes geothermal facilities in several markets, including the United States and international locations. Its experience is particularly important because geothermal development requires specialized knowledge of subsurface resources, drilling, plant design, reservoir management, permitting, and long-term operations.
For investors searching for a direct geothermal stock, Ormat is often the first company to examine. Its investment profile is closer to a specialized renewable-power and infrastructure company than to a speculative technology start-up.
Why Ormat Could Benefit
One of Ormat’s key advantages is its established operating experience. Developing a geothermal plant is not simply a matter of installing turbines. Companies must identify suitable underground resources, confirm reservoir characteristics, drill production and injection wells, design surface facilities, obtain permits, secure financing, connect to the grid, and maintain production over many years.
Ormat’s experience across these stages may help it evaluate projects more effectively than inexperienced entrants. It can also use knowledge gained from existing facilities to improve future plant design and operating performance.
The company may benefit from rising demand for firm renewable electricity. Utilities and large electricity users increasingly want clean power that is available outside daylight hours and can support grid reliability. Geothermal projects can potentially provide this service under long-term power-purchase agreements.
Ormat may also benefit from energy storage. Although storage is not the same as geothermal generation, combining geothermal assets with storage could improve flexibility and create additional revenue opportunities. A broader portfolio of geothermal, storage, and energy services may allow the company to address changing market requirements.
Another potential advantage is the recurring nature of power-generation revenue. Once a geothermal plant is operating successfully and selling electricity under a long-term contract, it may produce relatively predictable cash flow. This is different from an early-stage developer that has not yet completed its first commercial project.
Risks Facing Ormat
Ormat’s direct exposure is also its main risk. If a geothermal resource underperforms, the company may face a greater financial impact than a diversified oilfield-services supplier. Exploration results, well productivity, reservoir pressure, operating costs, and plant availability can all affect project returns.
The company is also sensitive to interest rates. Renewable-energy infrastructure requires substantial upfront capital, and higher borrowing costs can reduce project economics or delay construction. Investors should monitor debt levels, interest expenses, refinancing requirements, and the cost of capital used for new developments.
Permitting and transmission are additional concerns. A geothermal resource may be technically viable but commercially unattractive if the project cannot obtain environmental approvals or connect to a suitable electricity market. Transmission bottlenecks can delay revenue generation and increase development costs.
Ormat also competes with other sources of firm or flexible electricity. Natural gas remains widely available in the United States, while batteries, nuclear power, hydropower, demand response, and regional transmission expansion may compete for the same customers and investment capital.
What Investors Should Monitor
Investors reviewing Ormat should examine the company’s operating portfolio, development pipeline, construction schedule, equipment sales, power-purchase agreements, revenue growth, cash flow, and balance sheet.
Particular attention should be given to the difference between projects that are operating, under construction, fully permitted, contracted, or merely under evaluation. A large project pipeline may look impressive, but its value depends on resource confirmation, financing, construction execution, and the ability to sell electricity at attractive prices.
Investors should also examine plant availability, production trends, maintenance expenses, and any changes in expected project costs. Consistent operating performance can be more important than ambitious development announcements.
Company Overview
Baker Hughes is a diversified energy-technology company serving the oil and gas sector, industrial customers, and broader energy markets. Its operations include drilling technology, oilfield services, turbomachinery, energy equipment, liquefied natural gas infrastructure, digital systems, and industrial solutions.
Baker Hughes is not a pure geothermal company. Its geothermal investment case is based on the possibility that technologies developed for oil and gas can be adapted for geothermal projects. These technologies may include high-temperature drilling equipment, well systems, turbomachinery, compressors, monitoring tools, and project-engineering services.
As geothermal developers move toward deeper wells and more complex reservoirs, they may require suppliers with experience operating in harsh subsurface environments. Baker Hughes has decades of expertise in designing and supplying equipment for challenging energy projects.
Geothermal Growth Opportunity
The geothermal industry faces many of the same technical problems that the oil and gas industry has addressed over several decades. These include drilling deep wells, managing high pressures and temperatures, controlling fluids, maintaining well integrity, and optimizing underground reservoirs.
Baker Hughes could benefit if geothermal developers increasingly use established oilfield technology to reduce project risk and accelerate deployment. The company’s participation may occur through equipment sales, engineering contracts, strategic partnerships, or technology licensing.
The company’s involvement in geothermal projects connected with advanced developers illustrates how traditional energy suppliers may support next-generation geothermal systems. The commercial opportunity could become larger if enhanced geothermal projects move from pilot facilities into multi-hundred-megawatt developments.
Baker Hughes may also benefit from the broader energy transition. Technologies used in geothermal can overlap with carbon capture, hydrogen, underground storage, and other subsurface energy applications. This creates a wider opportunity than geothermal alone.
Why Diversification Matters
Baker Hughes offers a different risk profile from Ormat. Because its business is diversified, the company is not dependent on the success of one geothermal project or even on geothermal growth alone. Its oil and gas, industrial, and energy-infrastructure operations can provide revenue while emerging technologies develop.
However, this diversification also limits geothermal sensitivity. Even if geothermal deployment accelerates, the impact on total revenue and earnings may remain modest during the early stages. Investors buying Baker Hughes should therefore evaluate the entire company rather than assuming that geothermal announcements will immediately transform the stock.
The company’s performance may still be influenced more strongly by oil and gas capital spending, liquefied natural gas infrastructure, industrial demand, and global economic conditions.
Key Metrics to Review
Investors should monitor Baker Hughes’s orders, backlog, segment margins, free cash flow, research and development spending, and new-energy partnerships. Geothermal-specific contracts are particularly important, but they should be evaluated in relation to total company revenue.
The most meaningful development would be a pattern of repeat commercial orders from several geothermal developers. A single demonstration project may prove technical capability, but recurring orders would provide stronger evidence of a scalable market.
Company Overview
SLB, formerly known as Schlumberger, is a major global oilfield-services and subsurface-technology company. It provides drilling, reservoir characterization, well construction, production optimization, digital systems, and energy services to customers around the world.
Its geothermal relevance comes from its extensive knowledge of underground formations. The success of geothermal projects depends on understanding where heat is located, how fluids move through rock, how wells should be drilled, and how reservoirs will behave over decades of operation.
Enhanced geothermal systems require particularly sophisticated subsurface analysis. Developers may need to create or improve permeability in hot rock, connect injection and production wells, manage reservoir pressure, and monitor seismic and thermal behaviour. SLB’s existing capabilities may be adapted to these requirements.
Potential Role in Enhanced Geothermal
SLB could participate in geothermal through reservoir modelling, seismic interpretation, drilling services, completion systems, monitoring, and production optimization. Its global scale and technical workforce could help geothermal developers address a shortage of specialized engineering and project-management expertise.
The company may also be able to reduce costs by adapting existing tools rather than developing every system from the beginning. This could be valuable if geothermal developers seek to use standardized drilling practices and equipment.
The geothermal opportunity is particularly linked to the development of EGS and other next-generation technologies. If developers can prove that engineered reservoirs can produce reliable heat at commercial costs, demand for subsurface services could grow substantially.
SLB’s digital capabilities may also be relevant. Real-time data, remote monitoring, predictive maintenance, and reservoir simulation can help operators identify problems and improve the performance of complex geothermal assets.
Investment Limitations
SLB remains primarily an oilfield-services company. Its earnings are closely connected to exploration and production budgets, oil and gas prices, geopolitical conditions, and international drilling activity.
This means geothermal growth may not protect the company from a downturn in conventional energy markets. If oil and gas customers reduce spending, the resulting decline in the core business could outweigh early geothermal revenue.
Investors should also distinguish between strategic participation and material financial exposure. A company may have an important role in a geothermal demonstration while generating little revenue from that project. The geothermal thesis becomes more compelling when contracts, backlog, and reported segment revenue show measurable growth.
What to Watch
Investors should follow SLB’s new-energy announcements, geothermal partnerships, technology demonstrations, research and development activities, and commercial contracts. They should also evaluate traditional indicators such as international rig activity, customer capital expenditure, segment margins, and free cash flow.
The most important long-term question is whether SLB can turn its subsurface expertise into a meaningful new business while continuing to manage the cycles of the conventional oilfield-services market.
Company Overview
Halliburton is one of the world’s largest providers of oilfield services. Its activities include drilling, completion, cementing, stimulation, production enhancement, well intervention, and related technical services.
These capabilities are directly relevant to geothermal well construction. A geothermal project may require wells that withstand high temperatures, corrosive fluids, pressure changes, and repeated thermal cycling. Cementing and completion quality can determine whether a well remains productive and safe over its operating life.
Halliburton’s geothermal exposure is therefore connected primarily to the services and equipment required to develop underground reservoirs rather than ownership of geothermal power plants.
Why Halliburton Matters
Drilling is one of the largest costs and greatest risks in geothermal development. Every additional day spent drilling can increase project expenses, while a failed or underperforming well can reduce the economic value of an entire development.
Halliburton’s experience in complex well construction may help geothermal developers reduce these risks. Its services can potentially improve drilling efficiency, well integrity, fluid management, cement performance, and completion outcomes.
The company may become more relevant as geothermal developers use longer horizontal wells, multi-well systems, and engineered reservoirs. These projects require precise drilling and sophisticated completion methods.
Halliburton’s established customer relationships may also help it enter geothermal markets through existing energy companies that are expanding into clean-energy technologies.
Main Risks
Halliburton’s stock is primarily an oilfield-services investment. Its financial results may be affected by North American drilling, international exploration, hydraulic-fracturing activity, pressure-pumping demand, customer budgets, and energy prices.
Geothermal projects may also require modified equipment, different drilling schedules, and specialized operating procedures. A technology that works effectively in oil and gas may require further development before it can be used economically in geothermal environments.
Investors should not assume that geothermal growth will rapidly change Halliburton’s earnings. Instead, they should view geothermal as a potential long-term option within a much larger business.
Important Indicators
Relevant indicators include the number and size of geothermal contracts, high-temperature cementing research, completion technologies, partnerships with geothermal developers, and the company’s ability to create repeat business.
Investors should also monitor utilization, pricing, margins, and demand across Halliburton’s conventional oilfield-services operations. These factors are likely to influence the share price more strongly than geothermal developments in the near term.
Company Overview
Helmerich & Payne operates land drilling rigs and provides drilling technology and services. It is known for high-specification rigs, automation, directional drilling capabilities, and drilling-performance solutions.
Geothermal projects can require deep wells and precise well placement. Enhanced geothermal developments may use multiple wells connected through engineered underground reservoirs, making drilling accuracy and operational reliability particularly important.
Geothermal Opportunity
The company’s drilling technology may be useful in geothermal projects that require precise well trajectories, real-time monitoring, automation, and improved drilling efficiency. If geothermal developers adopt techniques from unconventional oil and gas, experienced drilling contractors could become valuable partners.
A geothermal drilling boom could create additional demand for rigs, raise utilization rates, and support day rates. Companies with modern equipment and strong technical capabilities may be better positioned than contractors operating older or less efficient rigs.
Helmerich & Payne could also benefit from broader growth in energy infrastructure. Even if geothermal grows slowly, demand for oil, gas, and other drilling activities may continue to influence the company’s performance.
Risks to Consider
Helmerich & Payne remains heavily exposed to the conventional drilling cycle. Lower oil and gas prices, reduced customer budgets, excess rig supply, or declining exploration activity could pressure utilization and pricing.
Geothermal projects may also progress slowly because of permitting, financing, resource confirmation, and construction delays. A company can be technically capable of serving geothermal customers without receiving enough contracts to materially affect its financial performance.
Investors should therefore examine geothermal contracts alongside conventional rig utilization, day rates, fleet age, customer concentration, debt, and cash flow.
What to Monitor
Investors should track geothermal-related contracts, drilling partnerships, rig modifications, automation investments, utilization rates, and customer announcements. They should also examine whether geothermal work is recurring and profitable rather than limited to one-off demonstrations.
The Role of Enhanced Geothermal Systems
Enhanced geothermal systems could be the most important technological development in the sector. Conventional geothermal requires naturally favourable underground conditions, but EGS attempts to engineer a reservoir in hot rock that lacks sufficient natural permeability.
The basic concept involves drilling wells into hot rock, creating or improving underground flow pathways, circulating fluid through the heated rock, and bringing the hot fluid back to the surface. The heat can then be used to generate electricity before the cooled fluid is reinjected.
The promise is significant because hot rock exists across much larger areas than conventional geothermal reservoirs. If developers can reliably create productive reservoirs, geothermal could become available in more regions of the United States and other countries.
The technical challenges are substantial. Developers must control stimulation processes, manage induced seismicity, maintain well integrity, sustain fluid circulation, and ensure that heat extraction does not decline too quickly. They must also reduce drilling costs enough to compete with other forms of electricity.
Investors should look for evidence rather than relying on theoretical resource estimates. Stronger evidence includes successful multi-well demonstrations, sustained production, commercial power contracts, repeatable drilling results, and clear cost reductions.
Geothermal and U.S. Electricity Demand
The United States is one of the most important markets for geothermal investment because it has extensive geothermal resources, advanced drilling expertise, large capital markets, and rapidly growing electricity demand.
Western states such as California, Nevada, Utah, and New Mexico have significant geothermal potential. Other regions may become relevant if EGS and closed-loop technologies prove capable of accessing heat outside traditional geothermal areas.
Data centers are an important potential source of demand. These facilities require reliable power and may be willing to sign long-term contracts for clean electricity. Geothermal developers that can provide firm generation near transmission infrastructure could become attractive partners.
The economics will depend on the price customers are willing to pay for reliability and clean-energy attributes. A geothermal project may be competitive even if its energy-only price is higher than some alternatives, provided it offers valuable capacity, emissions benefits, resilience, or other services.
U.S. investors should monitor federal tax policy, Department of Energy support, state renewable-energy standards, utility procurement programs, permitting rules, transmission expansion, and corporate clean-energy contracts.
Financial Risks of Geothermal Investing
Geothermal stocks can be affected by risks that are different from those associated with conventional renewable-energy companies.
The first is resource risk. A project may require expensive drilling before the resource is fully understood. If temperatures or flow rates are lower than expected, the project may need additional wells or redesign.
The second is construction risk. Geothermal plants involve complex civil works, drilling, turbines, cooling systems, pipelines, electrical equipment, and grid connections. Delays can increase costs and postpone revenue.
The third is financing risk. High interest rates can reduce the value of long-term electricity projects. Companies with weak balance sheets may need to issue shares or take on expensive debt.
The fourth is regulatory risk. Projects may face environmental reviews, land-use restrictions, water regulations, drilling permits, and seismicity concerns. Changes in policy can affect project timing and returns.
The fifth is technology risk. EGS, closed-loop systems, superhot-rock concepts, and other next-generation approaches may show technical promise but still require commercial validation.
Finally, there is valuation risk. Investor enthusiasm can push geothermal-related stocks beyond what current revenue and cash flow justify. A strong long-term industry outlook does not guarantee that every stock is attractively priced.
How to Build a Geothermal Watchlist
A practical watchlist should separate companies by business model. Investors can place Ormat in a direct geothermal category and the other companies in an indirect technology and drilling category.
The watchlist should include the following information for each company:
- Stock ticker and exchange.
- Market capitalization.
- Geothermal revenue, if disclosed.
- Operating geothermal capacity.
- Development pipeline.
- Major customers and contracts.
- Debt and cash position.
- Free cash flow.
- Capital-expenditure requirements.
- Exposure to oil and gas.
- Major regulatory or technical risks.
- Valuation metrics.
- Upcoming earnings and project milestones.
Investors should update the watchlist after quarterly earnings reports and major project announcements. They should be cautious when companies use broad language such as “geothermal opportunity” without disclosing contract value, project status, expected revenue, or commercial timelines.
