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...
Germany Invests €18.8 Million in Geothermal Energy at FH Münster
North Rhine-Westphalia is putting geothermal energy at the center of its strategy to build more sustainable, energy-efficient and research-driven infrastructure. The state government has committed €18.8 million to expand geothermal heating and cooling at FH Münster’s Technology Campus Steinfurt, creating a major real-world laboratory for geothermal heat pumps, energy efficiency and climate-neutral campus development.
The funding is part of the €60 billion Nordrhein-Westfalen-Plan für gute Infrastruktur, a 12-year infrastructure investment program described by the state as the largest investment program in North Rhine-Westphalia’s history. Of the total program, €2.3 billion is allocated to universities, research, higher education and knowledge transfer.
For geothermal energy, the Steinfurt project is particularly significant because it goes beyond simply installing a heating system. The campus is being transformed into a living laboratory where geothermal energy infrastructure becomes part of education and research.
Students and researchers will be able to work directly with the geothermal system, collect operational data in real time and investigate how heat pumps can become more efficient and practical for everyday applications.
€18.8 Million Geothermal Investment Targets Campus Decarbonization
The €18.8 million funding was formally presented on August 27, 2026, by North Rhine-Westphalia Minister of Culture and Science Ina Brandes to FH Münster President Professor Dr. Frank Dellmann.
The project, officially known as “Geothermie-Anpassung auf dem Technologie-Campus Steinfurt”, will be implemented jointly with the Bau- und Liegenschaftsbetrieb NRW (BLB NRW).
The central objective is to significantly expand the use of geothermal energy at the Technology Campus Steinfurt and adapt existing campus infrastructure to operate effectively with the lower temperature levels associated with geothermal heating.
According to FH Münster, geothermal energy is expected to eventually provide approximately 64 percent of the campus’s total heating demand.
That makes the project more than a demonstration installation. It represents a substantial shift in the energy architecture of a university campus, using locally produced geothermal heat to reduce reliance on conventional fossil-based heating systems.
Steinfurt Is Becoming a Geothermal Living Laboratory
One of the most important aspects of the project is its integration with teaching and research.
The geothermal system will operate as a Reallabor, or real-world laboratory. Rather than studying geothermal heat pumps only through simulations or laboratory-scale equipment, students will have access to an operating system under real-world conditions.
Sensors installed in the geothermal boreholes will provide operational information that students and researchers can analyze. They will be able to observe how the system performs in real time and investigate how its efficiency can be improved.
This approach creates a direct connection between geothermal deployment, engineering education and applied research.
For the geothermal industry, this is increasingly important. The transition toward low-carbon heating requires not only new equipment but also engineers, technicians and researchers capable of designing, operating and optimizing geothermal systems.
Steinfurt therefore provides an example of how universities can become active infrastructure laboratories while simultaneously preparing the workforce required for the energy transition.
From a 150-Meter Borehole to a Much Larger Geothermal System
The campus’s geothermal journey began in 2023, when FH Münster installed its first 150-meter-deep borehole.
Temperatures at that depth remain relatively stable at around 12°C. While 12°C may appear modest compared with temperatures required directly for conventional high-temperature heating systems, it provides a valuable heat source for heat-pump technology.
The first installation currently supplies the campus laboratory for measurement, control and regulation technology, as well as a large experimental ventilation system.
The next phase significantly increases the scale of the geothermal infrastructure.
The existing boreholes are being expanded toward depths of approximately 250 meters. In addition, 37 geothermal probes have already been added, while another 80 probes are planned beneath two new institute buildings.
These additional boreholes will increase the amount of geothermal energy available to the campus and create a much larger underground thermal resource connected to the university’s heating and cooling infrastructure.
Why 250-Meter Geothermal Probes Matter
The Steinfurt project illustrates an important principle in geothermal heating: geothermal systems do not necessarily require extremely deep drilling to deliver useful energy.
For building-scale heating and cooling, relatively shallow geothermal systems can utilize the stable temperature conditions underground. Heat pumps then upgrade that low-temperature energy to a temperature suitable for the building's heating requirements.
At Steinfurt, the geothermal resource will therefore work together with heat-pump technology rather than attempting to provide high-temperature heat directly from the ground.
This distinction is critical.
The geothermal system supplies the renewable thermal energy, while the heat pump provides the temperature lift.
The approach can be particularly attractive for buildings that can operate efficiently at lower heating temperatures, including campuses, offices, hospitals, residential buildings and modern commercial facilities.
Geothermal Can Provide Both Heating and Cooling
Another major advantage of the Steinfurt system is that the same infrastructure can support both heating in winter and cooling in summer.
During heating operation, heat is extracted from the ground and transferred into the campus through a heat-pump system.
During cooling operation, the process can be reversed, allowing heat from the buildings to be transferred back into the ground.
This creates an important seasonal energy-storage function.
Instead of viewing the subsurface simply as a source of heat, the ground can effectively become a thermal battery. Heat rejected into the ground during summer can influence underground temperatures, while the stored thermal energy can subsequently participate in winter heating operations.
This heating-and-cooling capability is one of the reasons geothermal heat-pump systems are attracting growing attention in the decarbonization of buildings.
Heat Pumps Turn Low-Temperature Geothermal Energy Into Useful Heat
The fundamental technology behind the Steinfurt project is the geothermal heat pump.
A heat pump uses a refrigerant circulating through a thermodynamic cycle. The refrigerant changes between liquid and gaseous states, while pressure and temperature change throughout the process.
The system extracts thermal energy from the ground and upgrades it to a higher temperature that can be delivered to the building's heating system.
According to the North Rhine-Westphalia government, approximately 75 percent of the energy supplied by the heat pump can come freely from nature, with electricity required primarily to operate the system itself.
The precise performance of any geothermal heat-pump system depends on factors including ground conditions, system design, flow temperatures, building efficiency and heat-pump performance. Nevertheless, the fundamental advantage remains the same: electricity is used to move and upgrade renewable heat rather than generating all of the heat directly.
Existing Buildings Must Be Adapted for Geothermal Heating
One of the most important lessons from Steinfurt is that installing geothermal probes is only one part of a successful geothermal heating project.
Existing buildings and their heat-distribution systems must also be adapted.
Geothermal heat pumps typically operate most efficiently when buildings can be heated using relatively low supply temperatures. Older heating systems, particularly those designed around fossil-fuel boilers, may have been designed for significantly higher temperatures.
As a result, FH Münster will undertake various structural and technical measures to adapt existing buildings and, particularly, the campus heat-distribution network to the lower temperature level of geothermal energy.
This is a critical consideration for universities, municipalities, commercial property owners and developers considering geothermal heating.
Deepening boreholes alone does not guarantee an efficient geothermal building. The entire energy system—including building insulation, heat distribution, radiators or underfloor heating, controls and heat-pump operation—must work together.
FH Münster Targets 64 Percent of Heating Demand From Geothermal Energy
The scale of the planned transformation is significant.
FH Münster expects geothermal energy to cover around 64 percent of the campus’s overall heating demand in the future.
This creates a useful case study for other large institutions seeking to decarbonize heating.
University campuses often have characteristics that make them particularly suitable for geothermal systems. They can contain multiple buildings with relatively predictable heating and cooling loads, centralized energy infrastructure and sufficient land or development areas for geothermal installations.
They also provide an additional benefit that conventional commercial projects may not have: the opportunity to combine energy infrastructure with education and research.
Steinfurt is effectively turning its heating system into part of the curriculum.
Germany’s Geothermal Opportunity Extends Beyond Power Generation
When geothermal energy is discussed globally, much of the attention focuses on geothermal electricity generation.
Germany’s situation highlights another enormous opportunity: geothermal heating and cooling.
Unlike geothermal power generation, which generally requires sufficiently high underground temperatures, geothermal heating can work with lower-temperature resources when combined with efficient heat-pump systems.
This expands the geographic potential of geothermal energy.
For a country like Germany, where heating represents a major component of building energy consumption, the ability to replace fossil gas and oil heating with renewable thermal energy can have substantial climate and energy-security implications.
Projects such as Steinfurt demonstrate how geothermal energy can become integrated into everyday infrastructure rather than remaining limited to large power plants.
The NRW Infrastructure Plan Creates a Platform for Clean Energy
The Steinfurt geothermal investment forms part of the broader Nordrhein-Westfalen-Plan für gute Infrastruktur.
The €60 billion program will be implemented over a 12-year period and covers infrastructure modernization across the state.
Approximately €2.3 billion is dedicated to universities, university medicine and research institutions.
The state says investments are intended to address major future challenges, including artificial intelligence, digitalization, healthcare, energy efficiency and sustainability.
For the geothermal sector, the inclusion of energy efficiency and sustainability within a major public infrastructure program is particularly noteworthy.
It demonstrates how geothermal heating can move from being viewed as a niche technology toward becoming part of mainstream public infrastructure planning.
A Blueprint for Climate-Neutral University Campuses
FH Münster President Professor Frank Dellmann described the Steinfurt project as part of the university’s ambition to create a climate-neutral campus and contribute to North Rhine-Westphalia’s target of climate neutrality by 2030.
The concept is straightforward but powerful: produce renewable thermal energy locally, use it to heat and cool university buildings, and simultaneously use the system as an educational and research platform.
That model could potentially be replicated elsewhere.
Universities have extensive buildings, laboratories, student housing, offices and research facilities. Many also have large areas of land available for geothermal infrastructure.
By integrating geothermal systems into campus energy planning, universities can reduce operational emissions while creating infrastructure that supports engineering and energy research.
The Workforce Dimension of Geothermal Energy
Perhaps one of the most strategically important elements of the Steinfurt project is not the number of geothermal probes—it is the people who will learn how to operate them.
Europe's energy transition requires a workforce capable of handling increasingly complex energy systems.
Geothermal projects require expertise across drilling, geology, hydrogeology, heat-pump engineering, building energy systems, controls, data analysis and operations.
A real-world laboratory provides students with exposure to these disciplines under actual operating conditions.
Students can see how changes in system parameters influence performance rather than relying exclusively on theoretical models.
They can analyze real data, evaluate efficiency, identify operational challenges and investigate opportunities for optimization.
This could help bridge one of the industry's major challenges: the growing demand for geothermal expertise as deployment expands.
Why This Project Matters to the Global Geothermal Industry
From an international perspective, the FH Münster investment provides several important signals.
First, geothermal energy is increasingly being positioned as a building-scale heating and cooling solution, not merely an electricity-generation technology.
Second, governments are beginning to combine geothermal infrastructure investment with research and workforce development.
Third, public institutions are becoming important early adopters of geothermal heating systems.
And fourth, the project demonstrates that geothermal deployment must be considered as an integrated energy-system challenge.
The boreholes, heat pumps, buildings, distribution networks, controls and users all need to work together.
That systems-level approach could become increasingly important as Europe attempts to reduce fossil fuel consumption in the heating sector.
Steinfurt Could Become a Reference Point for Geothermal Heating
The Technology Campus Steinfurt is not the largest geothermal project in Europe. Its importance lies elsewhere.
It combines renewable heat production, building decarbonization, research, education and workforce development in one project.
The campus will effectively function as a test environment where the performance of geothermal heat pumps can be studied under real operating conditions.
That creates a feedback loop:
Geothermal infrastructure generates data → students and researchers analyze the data → research improves system performance → improved knowledge supports future geothermal deployment.
If successful, this model could be highly valuable for other universities and public institutions considering geothermal heating.
What Comes Next for Geothermal Energy in North Rhine-Westphalia?
The €18.8 million commitment at FH Münster should be viewed within the broader transformation of North Rhine-Westphalia's energy infrastructure.
The state's infrastructure program includes investments in energy efficiency, climate protection, building modernization, research and science.
Geothermal energy sits directly at the intersection of these priorities.
Its ability to provide continuous thermal energy, support both heating and cooling, and work with heat pumps makes it particularly relevant to the decarbonization of buildings.
The success of Steinfurt could therefore influence how other public institutions evaluate geothermal heating.
If the campus demonstrates reliable operation, strong efficiency and meaningful research outcomes, the project could become a reference case for universities, municipalities and other large building owners across Germany and beyond.
Alphaxioms Takeaway
The €18.8 million investment in geothermal energy at FH Münster represents something larger than a university heating upgrade.
It is an example of how geothermal energy can become part of a broader clean-energy ecosystem—one that combines infrastructure, education, research, energy efficiency and decarbonization.
With geothermal systems expected to supply approximately 64 percent of the campus's total heating demand, 37 probes already added and another 80 planned beneath two new institute buildings, Steinfurt is significantly expanding its geothermal footprint.
But the most interesting element may be the campus's role as a real-world laboratory.
Students will not simply study geothermal technology from textbooks. They will work with an operating system, examine real-time data and investigate how heat pumps can become more efficient and practical.
For the geothermal industry, that is exactly the kind of infrastructure needed to accelerate deployment.
Germany's geothermal story is increasingly becoming a story about heat—not only power. And at Steinfurt, that story is being built directly into the university campus.
As Europe looks for scalable alternatives to fossil-based heating, projects like FH Münster could provide a practical blueprint: use the ground as a renewable thermal resource, combine it with highly efficient heat pumps, adapt buildings to low-temperature heating, and train the engineers who will build the next generation of geothermal systems.
The investment from North Rhine-Westphalia sends a clear message: geothermal heating is moving deeper into Europe's mainstream infrastructure strategy.
