The Greater Munich area is considered a pioneer in Germany in the use of climate-friendly heat from deep underground. Now, the Bavarian capital and the surrounding municipalities want to explore the further development potential of this regional energy resource and make its use sustainable. DMT GmbH & Co. KG, Essen/Germany, a company of the TÜV NORD GROUP, was commissioned to carry out seismic exploration of the subsoil as part of the GIGA-M research project. The largest measurement campaign to date in an urban settlement area in Germany began in the first half of 2026.

The GIGA-M research project, funded by the Federal Ministry for Economic Affairs and Energy (BMWE), is a joint venture between the Technical University of Munich (coordination), Stadtwerke München (seismic management), Energie-Wende-Garching (seismic partner), the Ebersberg-Munich Energy Agency, the district of Munich and the state capital of Munich. The aim of the seismic campaign is to identify suitable hot water reservoirs beneath Munich. To this end, the subsoil is being surveyed seismically over a large area in order to obtain an accurate figure of the geological structures. The data obtained will also help to select specific locations for new geothermal plants, optimally integrate existing plants and further expand the supply of renewable heat. In this way, GIGA-M is laying the foundation for a secure, climate-friendly and affordable heat supply and taking the Munich region an important step closer to achieving climate neutrality by 2045.

“With Munich, one of Germany’s largest metropolitan areas is increasingly turning to geothermal energy. The planned Acceleration Act will also further strengthen the legal framework for geothermal energy. We expect demand to remain high, as many municipalities are looking for ways to achieve their climate targets as part of their municipal heat planning,” says Maik Tiedemann, CEO of DMT and CEO of the TÜV NORD GROUP Business Unit Energy & Resources.

The greater Munich area is located in the pre-Alpine Molasse Basin, a region that is particularly well suited for geothermal use. DMT has been supporting the Munich region in exploring the deep subsurface for usable heat since 2007. The new, large-scale seismic measurement campaign is intended to create the data basis for a significant expansion of geothermal capacity from the current approximately 400 MW to over 1 GW – enough to supply tens of thousands of additional households with climate-friendly heat. With a measurement area of 1,100 km², this is the largest seismic survey ever conducted in a German settlement area.

In order to capture the potential deep underground, special measuring vehicles (vibro trucks) send light seismic impulses into the ground (Figure 1). These impulses are reflected by rock formations and recorded by a network of geophones (receiver modules). The data obtained is then used to create a detailed 3D model of the subsurface. Based on this model, precise target areas for the development of hot thermal water can then be determined.

“Previously, the largest contiguous urban area in Germany to date was seismically surveyed in Münster at the end of 2024 – now Munich is taking over. With more than four times the area of the project in Münster, the exploration in Munich is of a unique scale. Such large-scale investigations in densely populated urban areas are challenging, but with the necessary expertise they are feasible and indispensable if we want to tap the geothermal potential for a future-proof heat supply,” says Christian Henke, Head of Seismics, Exploration & Processing at DMT.

Deep geothermal energy plays a central role in the transformation of heat supply in Germany. And its potential is enormous: according to the German Geothermal Association, it could cover at least 25 % of the country’s heat demand. Its importance is also increasingly being recognised at the federal level – the German government is providing over 1.5 bn € for its expansion by 2030. The new “Deep Geothermal Energy for Heating Networks” funding programme provides targeted support for municipal projects in particular. According to the Federal Environment Agency, the use of deep geothermal energy can save up to 40 Mt/a CO₂ – a decisive contribution to achieving climate neutrality by 2045.

Public acceptance is also high: According to recent surveys, e. g. by Fraunhofer IEG from 2024, more than 60 % of Germans are in favour of expanding the use of geothermal energy, especially if the potential impact on residents remains low. Never before has deep geothermal energy been so high on the political agenda – and it is becoming a key factor in ensuring a secure, affordable and climate-neutral heat supply. (DMT/Si.)

On 18th and 19th June 2026, the MiningForum will once again take place at the Hotel Estrel Berlin, Berlin/Germany, and bring together leading experts, decision-makers and thought leaders from the German, European and international raw materials industry. As one of the most important networking platforms, the conference has been dedicated to the pressing challenges and opportunities of a sustainable raw materials supply for over 30 years.

Under the motto “Raw Materials Momentum”, the MiningForum will highlight the crucial role of the raw materials sector for the diverse transformation tasks and far beyond. Raw materials form the foundation of our modern lives, from everyday products to high-tech innovations. MiningForum 2026 shows how the sector can fulfil its social mission efficiently, competitively and sustainably.

The event is characterised by a strategic partnership: Prof. Elisabeth Clausen, Head of the Institute for Advanced Mining Technologies (AMT) at RWTH Aachen University, Aachen/Germany, and Jens-Peter Lux, Managing Director of DMT GROUP, Essen/Germany, are combining their scientific and industrial expertise to provide important impetus for the industry with the MiningForum (Figure 1).

MiningForum 2026 offers a high-profile, international platform for dialogue between stakeholders from politics, business, science and civil society and provides impetus for innovative technologies, strategic partnerships and sustainable mining.

“The increasing uncertainty of global supply chains emphasises how urgently we need a resilient supply of raw materials. Only through sustainable strategies and innovative technologies can we create the basis for a stable and future-proof economy and society,” says Prof Clausen.

Cooperation between all relevant players is essential for the future of the raw materials sector. The cooperation with the AMT is an example of how industrial pragmatism, technological innovation and applied research can make a significant contribution to a secure and sustainable supply of raw materials.

“A secure and sustainable supply of raw materials can only be guaranteed through the interaction of industry, science, politics and civil society. Together, we must create suitable market mechanisms, drive innovation and develop sustainable solutions in order to successfully meet the challenges of the future,” explains Lux.

The conference offers participants an outstanding opportunity for knowledge exchange, an established platform for networking and for developing new partnerships to work together on the present and future of a resilient, reliable and sustainable supply of raw materials. (DMT/Si.)

DMT GmbH & Co. KG, Essen/Germany, an independent, global engineering and consulting company, launched the newest model of the GYROMAT series at INTERGEO 2024: the GYROMAT 6000 (Figure 1), the most accurate gyroscope measuring system for high-precision surveys, such as tunnel construction or shipbuilding. It combines the tradition of absolute precision of the GYROMAT series with a new feature that allows the gyroscope to access even the most difficult and confined spaces like microtunnels and ship hatches.

The presentation of the GYROMAT 6000 at INTERGEO 2024, an exhibition and platform for innovative solutions in geoinformation technology, reflects DMT’s commitment to innovation and excellence and is a significant step forward in the evolution of precision surveying technology. Jens-Peter Lux, DMT Managing Director and Head of Natural Resources & Infrastructure of the TÜV NORD GROUP Business Unit Energy & Resources, highlights how the GYROMAT 6000’s combination of high precision and portability is set to redefine surveying: “The GYROMAT 6000 is the next generation in surveying, providing engineers with unparalleled accuracy and reliability. Its advanced features, especially its portability, will significantly improve the surveying process and allow engineers to push the boundaries of what is possible in precision measurement in challenging terrain and under difficult conditions.”

The GYROMAT 6000 is the most accurate surveying gyroscope in the world as it reliably points north and compensates for potential sources of error like refraction, error propagation or even plumb line errors when determining direction from a shaft and delivering measurement results with an accuracy of 0.8/1000th of a gon. Jörg Niese, product manager at DMT and in charge of the GYROMAT series, explains how accurately the GYROMAT 6000 measures with the following example: “If you were to cut a cake into 400 pieces and then cut one of these little pieces of cake into 1,000 even smaller pieces, then you would have an idea of the accuracy involved. And the beauty of the GYROMAT 6000 is that you can use it for measurements anywhere: in a tunnel, in a ship’s hull or in an industrial hall.” This is possible because the GYROMAT 6000 can operate where GPS signals are unavailable and it now comes with the ability to separate the gyroscope module from the total station which makes it easy to transport it into the smallest spaces like microtunnels or through ship-hatches. With fully automated measurement sequences, pre-orientation-free measurement procedures and advanced monitoring functions the GYROMAT 6000 stands as a proof of precision and adaptability that is applicable in tunnel construction, shipbuilding, aerospace, and industrial surveying.

With the launch of the GYROMAT 6000, DMT continues the success story of the GYROMAT series as the gold standard of survey gyroscopes. The GYROMAT gyroscopes are renowned for ensuring high-precision orientation and control anytime, anywhere and for providing high-precision measurements for cost-effective planning reliability. Due to their unmatched accuracy, DMT’s GYROMAT series are the number one measuring instruments for control measurements in many of the world’s largest tunnel construction projects like the Eurotunnel, the Brenner Base Tunnel, and the Gotthard Base Tunnel.

DMT GmbH & Co. KG, Essen/Germany, part of the TÜV NORD GROUP’s Energy & Resources business unit, has acquired a majority stake in the Brazilian company Saga Consultoria and is bringing the company under the DMT brand umbrella. The engineering and consulting service provider is thus expanding its presence with a location in Belo Horizonte. Since 17th April 2024, customers in Latin America have been able to access the entire raw materials service portfolio and beyond via the new DMT hub.

For Jens-Peter Lux, Managing Director of DMT, the majority stake in Saga Consultoria opens up the opportunity to tap into future markets: “Thanks to its significant reserves of mineral raw materials, Brazil plays a key role in the energy and mobility transition, digitalisation and greater sustainability in the raw materials sector.” Maik Tiedemann, CEO of the Business Unit Energy & Resources of TÜV NORD GROUP and DMT, adds: “In addition, the country and our new acquisition offer access to other important markets in Latin America, such as the infrastructure, construction and energy sectors. We look forward to demonstrating the DMT brand and our capabilities in this region as well.”

The Saga Consultoria team consists of 15 geologists, mining engineers and technicians under the leadership of company founders Saulo Liberato and Luiz Gabriel Oliveira Lima (Figure 1). In the past, Saga Consultoria focussed on consulting services in the mining sector and prepared feasibility studies, profitability analyses and resource assessments, among other things. As DMT, Saga Consultoria now also provides access to the comprehensive portfolio along the entire raw materials value chain and beyond.

DMT’s service portfolio in the raw materials sector covers all stages of the value chain. These include resource exploration and evaluation, feasibility studies and detailed mine planning, construction supervision and project management, engineering consulting, optimisation and training, digitalisation and automation, due diligence for the finance and insurance sector, decommissioning concepts and planning, as well as sustainability­/­ESG concepts and implementation consulting.

DMT is also active in the plant engineering & process engineering, infrastructure & construction and energy markets. Companies and public institutions in Latin America can now also be supported by DMT-Goup, e. g. in geothermal projects, plant planning and tunnelling. (DMT/Si.)

The DMT GROUP, Essen/Germany, a globally active company for engineering services and consulting of the TÜV NORD GROUP, is repositioning itself along the entire value chain and, as a general contractor for deep geothermal energy, accompanies customers from the idea to the finished heating plant and the first kilowatt hour of heat generated.

When planning projects and developing potential sites for deep geothermal heating plants, municipal utilities, energy suppliers and companies are often under considerable time pressure and have to deal with a high degree of complexity on the way to decarbonising their heating networks. DMT provides them with new, comprehensive support models as a general contractor.

DMT’s expertise in the field of deep geothermal energy covers all the process steps required for commissioning a geothermal heating plant: project planning and design with application and approval procedures, public participation, feasibility study, economic feasibility study, risk analysis and funding advice. DMT then takes over the site investigation using 3D seismics as well as the drilling planning, drilling and borehole measurements, data processing and modelling. Finally, the last phase of the project involves the planning and construction of the plant, right up to the connection of the finished heating plant to the grid.

With DMT as general contractor, the effort for customers is minimised. All responsibilities, planning and implementation tasks lie with a single contractual partner, including schedule and budget planning as well as interface management and comprehensive project management. This makes the highly complex path to a geothermal heating plant more manageable for customers and involves considerably less effort on their part − regardless of whether DMT takes over everything completely or parts of the service chain.

DMT has already provided support for a large number of deep geothermal projects, including seismic surveys for GeoHardt GmbH, a subsidiary of MVV and EnBW, one of the largest inner-city 3D seismic surveys ever carried out for Stadtwerke München and the determination of the geothermal potential of the Vienna region for OMV and Wien Energie.

With the increased attention on the part of federal and state politicians for deep geothermal energy in Germany and an improvement in the framework conditions, e. g., in federal funding for efficient heat grids (BEW), DMT is expecting considerably stronger demand for support in project implementation in the coming months and years. This naturally also affects the planning of the capacities that DMT makes available to its customers.

“As soon as the recently submitted BEW funding applications are approved, customers will need advice, site investigation and plant engineering. We have also prepared for this with our capacities. With our setup as a general contractor, we can relieve our customers considerably − and ultimately accelerate the energy and heat turnaround,” explains Maik Tiedemann, Managing Director of DMT.

DMT GmbH & Co. KG, a TÜV NORD GROUP company based in Essen/Germany, has acquired a 51 % stake in Prüfzentrum für Bauelemente GmbH & Co. KG (PfB), based in Stephans­kirchen near Rosenheim/Germany. The transaction took place on 1st December 2022. With the participation both companies deepen their cooperation of many years in the testing and certification of construction elements. In the alliance, the respective customers are now offered a comprehensive service from a single source.

The current shareholders of PfB, Rüdiger Müller and Matthias Demmel, will remain involved in the company in the future. Demmel will continue to head the company as managing director. In addition, Daniel Rüdiger Müller, the son of the company’s founder, will join the management team as an authorised signatory. In addition, Demmel will be supported in future by Christoph Sinder, who heads DMT’s Plant & Product Safety business unit. From a technical and organisational point of view, PfB is linked to DMT’s Fire Testing business segment, which is headed by Stefanie Steinmeier.

Stefanie Steinmeier says: “By participating in PfB, we at DMT are significantly strengthening our position in the market for testing and certification of construction elements. Together with other services from the TÜV NORD GROUP, customers from the construction elements sector are offered a strong partner. In this respect, the participation is a logical step.”

PfB Managing Director Matthias Demmel adds: “The decisive factor for the transaction is the synergy effects that can be achieved. By integrating our services, we will be able to offer our customers an even larger testing portfolio in the future while maintaining our independence as a testing and certification body.” Company founder Rüdiger Müller adds: “For us, it is important that test processing is carried out flexibly in line with the needs of our customers and in intensive exchange with them. We share this aspiration with DMT and the entire TÜV NORD GROUP and are therefore expanding our cooperation even further.”

PfB has more than 40 years of experience in numerous areas of testing such as climate, air/water/wind, permanent function and smoke protection as well as various special tests on building elements such as doors, gates, windows, fittings and facades and is recognised as an accredited and notified testing and certification body.

DMT GmbH & Co. KG, a TÜV NORD GROUP company based in Essen, will be taking part in GeoTHERM expo & congress, the largest geothermal trade fair and congress in Europe, on 2 and 3 March 2023. Trade visitors, media representatives and decision-makers will have the opportunity to exchange views with DMT’s geothermal experts on the service portfolio for deep geothermal energy and to discuss solutions for all development phases from feasibility to site investigation and plant engineering.

In addition to DMT, over 150 other national and international exhibitors are expected. Supplemented by an extensive programme of lectures and workshops, the trade fair covers the entire spectrum of geothermal energy and is considered one of the most important meeting places for the industry.

In view of the challenges posed by the energy transition and the desired independence from the import of fossil fuels, deep geothermal energy in particular is of central importance – it can cover up to 25% of the demand for thermal energy in Germany. And since about one third of energy consumption in Germany is used for heating and hot water, municipalities and utilities that have recognised the unlimited heat potential of deep geothermal energy can now become pioneers in climate protection and guarantors of supply security.

While the political course is gradually being set for the expansion of deep geothermal energy, the realisation of projects still depends on many preconditions. DMT has therefore set itself the task of supporting customers in all phases of a geothermal project, from project initiation and the necessary seismic measurements to approval, plant construction and commissioning.

“Our customers can rely on DMT’s expertise when it comes to licensing issues, the wide range of funding opportunities, exploration, plant engineering, environmental impact assessments, and the involvement of the public and public interest groups. The same applies to the planning of wells and facilities,” explains Dr Boris Dombrowski, Deputy Head of Geo-Energy & Resources at DMT. “Even though DMT is primarily visible with its vibro-trucks in the context of exploring potential, our service portfolio encompasses all aspects of planning, design and consulting,” adds Prof. Dr Bodo Lehmann, Head of Geo-Energy & Resources at DMT. “We look forward to exchanging ideas with customers, interested parties and the press at GeoTHERM.”

Dr Boris Dombrowski and Prof. Dr Bodo Lehmann will be on site throughout the GeoTHERM and will be available for discussions.
