Clean and sustainable, an infinite mineral resource that contributes to an environmentally friendly energy supply: With the demand for climate-friendly, renewable energy, the focus is on the huge potential of inexhaustible geothermal energy, directly beneath our feet. At depths of around 3,000 meters and more, thermal waters are so hot that there is no need for a heat pump and therefore no additional electricity.
Deep geothermal energy can supply more than 25% of the required heat energy in Germany and thus make an important contribution to achieving climate targets. A move away from fossil-based energy generation simply cannot be achieved without the expansion of renewable, climate-friendly energies such as deep geothermal energy.
DMT demonstrates hands-on expertise at every stage of the project. We offer solutions across the entire process chain that support the site search, minimize the drilling risk, increase safety, minimize the costs of extraction, and increase productivity. DMT has been providing consulting services and geophysical surveys in numerous geothermal projects for more than 15 years.
DMT will help you get your deep geothermal project off to a successful start. We work with you to determine the foundations and regulations regarding location, technical possibilities and market conditions. On this basis, we work out a benefit and risk assessment and calculate the economic viability of the project. These preparations finally lead to a project structure plan for all subsequent phases. In this way, we set the course for a successful project right from the start - technically, commercially and, last but not least, socially through early public participation and information.
We are industry leaders in subsurface exploration and in determining the potential for deep geothermal energy exploitation. Initial typical DMT services include the planning and execution of 2D/3D seismic surveys, their evaluation, subsurface modelling, as well as simulation and bore path planning. Furthermore, we are on hand as an experienced project partner when it comes to obtaining all the necessary permits and approvals as well as performing environmental impact assessments.
Comprehensive geophysical exploration by DMT's experienced experts is absolutely vital before any municipality or company even considers commissioning kilometer-deep drilling. This is the only way to find out whether a site is at all suitable for geothermal energy untilization and whether drilling can be carried out at low risk.
If the site investigation is successful, we work with you to implement the final steps on the way to a geothermal heat plant. DMT draws up operating plans and handles the planning of both the building and the plant, as well as the subsequent plant engineering. We support you with connection to the grid and plant commissioning, right up until the first kilowatt hours from your deep geothermal energy supply start flowing.
The economic efficiency and price certainty of deep geothermal energy of currently 0.02 euro cents per kilowatt hour of thermal energy is not only attractive for municipal heating networks, who can convert surrounding settlement areas to sustainable thermal energy promptly and cost-effectively - with commercial success and entirely in line with climate targets.
In addition, larger agricultural operations can supply stables or greenhouses with heat, or the wood industry can dry products quickly and cost-effectively. With the appropriate technology, industry can easily obtain and use process temperatures of up to 700 °C from geothermal energy. Higher temperatures up to 1,200 °C are technically more complex - but even these existing systems appear promising.
According to the German Ministry of Economic Affairs and Climate Action, fifty percent of heat in Germany is to be generated in a climate-neutral manner by 2030. Politicians have committed themselves to preparing the ground for this and to accelerating procedures. Comprehensive subsidy programs must be set up and legal risk mitigation created for the expansion of geothermal energy. Cities and municipalities must be guaranteed that their geothermal project will be covered by an exploration risk insurance policy.
As a result of this political will, geothermal energy has now irreversibly become one of the most important building blocks for improving the competitiveness of municipalities and companies in the long term and thus leading Germany as an industrial location into a more secure future.
"The opening balance sheet on climate protection of January 2022 therefore already contains the concrete goal of developing a geothermal potential of 10 TWh in medium-deep and deep geothermal energy as far as possible by 2030, thus increasing tenfold the current input into heating networks from this source. To achieve this, we want to initiate at least 100 additional geothermal projects by 2030, connect them to heating grids, and make geothermal energy usable in residential buildings, neighborhoods, and industrial processes. Regions where geothermal energy is suitable are therefore to be identified in an exploration campaign and the information made available to local authorities. At the same time, all questions of safety and environmental protection should be considered from the outset," explains the ministry.
In the field of deep geothermal energy, various techniques are currently being used and tested in Germany: These include the classic deep boreholes which, as doublets or triplets, use the deep rock with the water circulating there to generate heat and/or electricity, deep geothermal probes in the area of direct heat generation, and combinations of both. But also the subsequent use of old mining pits or mine waters for geothermal applications is under investigation.
DMT is a member of the world's second largest geothermal association, Bundesverband Geothermie e.V., through which we are integrated into national and international networks such as the International Geothermal Association (IGA), the European Geothermal Energy Council (EGEC) and the Bundesverband Erneuerbare Energien (BEE).
Furthermore, we are represented in the Geothermal Energy Expert Committee of GDBM, whose aim is to promote further development of this form of energy. The regular committee meetings are attended by project developers and operators, universities, engineering companies, suppliers and authorities. The focus is on the use of warm water from former mines as well as on deep geothermal energy, i.e. the collection of ground heat by means of borehole mining.
Since 2017 DMT has also been a partner in Greentech.Ruhr, a network of innovative companies, research and educational institutions and various public institutions in the environmental sector. The Greentech.Ruhr project is an initiative of Business Metropole Ruhr GmbH, whose aim is to promote the Ruhr Metropolis worldwide as the leading area for the development and provision of environmental services and solutions.

Detailed site exploration is the basis for further action and one of our central business areas. As early as the exploration stage, commercially significant advantages can often be achieved. Precise planning, thorough exploration and interdisciplinary data evaluation and geological interpretation are the foundations for successful projects.
Seismic structural exploration, proven in oil and gas exploration among others, combined with state-of-the-art computer-aided interpretation, determines the best site, optimizes drilling planning and thus makes your projects more successful and safer.
A significant step in the processing of 2D/3D seismic data is processing. DMT's experienced specialists can provide you with optimum solutions and meaningful results.
Many years of experience in the interpretation and modeling of geological and geophysical data characterize our interdisciplinary team. In combination with state-of-the-art software, reliable results are delivered as a basis for decision-making for further project development - the basic requirement for any geothermal project.
In order to use a geothermal plant efficiently in the long term, detailed knowledge of the reservoir properties is essential. Based on geological modeling, different usage scenarios can be simulated to gain knowledge about heat exchange, cooling behavior or flow properties.
To make a geothermal project a success, seamless process advancement is essential. Especially in the transition from exploration to drilling and then from extraction to heating plant technology.
A drilling site for injection and production wells requires precise technical planning. We are experienced in all detailed planning and take care of securing the necessary permits.
Drilling planning is crucial for the successful sinking of deep boreholes. This involves optimizing the drilling paths, selecting the appropriate drilling rig, and dimensioning the casing. But the preparation of time and cost schedules and the preparation of the drilling tender are also tasks that DMT can handle professionally for you.
Safety is paramount in any geothermal project. Under the three keywords measurement, preservation of evidence and assessment, DMT offers a comprehensive range of seismological monitoring services including measurement, assessment and expert opinions.
Borehole logging in geothermal wells is challenging due to high temperatures and unique lithologies. In particular, geological fault and fracture systems of hydrothermal reservoir rocks play an important role in the planning and design of heating plant equipment. DMT has the necessary tools and expert know-how.
