Behringer + Dittmann Bohr

Geothermal area of activity: Specialization in near-surface geothermal energy with borehole heat exchangers down to a depth of 200 m. If necessary, complete geothermal development right into the building, including a pre-assembled and pressure-tested brine distributor. Recognized position of the drilling and use notification at the responsible authority as a certified DVGW specialist company. Objective and individual advice for each individual case based on our many years of practice (since 1990) and experience to achieve an optimal price-performance ratio. For larger systems, all preparatory measures to create a thermal response test with EED simulation are carried out to optimize the design of a geothermal probe field.


Bentec is your trusted worldwide partner in made-to-measure systems for oil, gas and geothermal drilling and premium oilfield equipment. We are completely geared towards health, safety and the environment.


EWM is a company that performs measurements needed for the utilisation of geothermal heat and develops geophysical measurement technology. EWM is headquartered in Bremen.

Geo-En Energy Technologies

As a business unit within GASAG Solution plus GmbH, Geo-En is a leading specialist in renewable energies. We develop and plan innovative energy systems that protect the climate and pay off - for new and existing buildings and for entire districts. Benefit from our many years of practical experience: As a plant constructor, Geo-En has built numerous geothermal plants itself in recent years. Our team uses this experience today to provide you with the entire spectrum of engineering and planning services: from object analysis to building and system simulation, the development of a tailor-made energy concept, engineering to the operational management of the system. Self-developed IT solutions like our Geo-En | EnergyNode enable the operational management and optimization of complex...


GeoAlto stands for sustainable heat and cold from the earth. Near-surface geothermal energy is a central component of the heat transition and is available year-round at almost every location as an energy source for heating and cooling buildings. Geothermal energy is also increasingly being used as "cold local heating" for the decentralized supply of entire districts or groups of buildings. With our expertise, we ensure the successful use of geothermal energy for an environmentally friendly and comfortable indoor climate of the future.


GeoDienste GmbH sees itself as a service company that works on geological, hydrogeological and water management as well as geothermal tasks and issues and develops their solutions. Based on the special technical qualification of the geoscientific and engineering staff, both in the field of practice and in the development of complex processes according to a scientific-theoretical approach, it is ensured that even for the most demanding geological, hydrogeological and geothermal tasks, targeted and timely solutions are found being found.
