Geothermal Energy
The Underestimated Energy Source

The energy transition is one of the key challenges of our time. While the expansion of renewable electricity generation from wind and solar energy has already made great strides, there is still a lot of catching up to do in the area of sustainable heat supply. More than 50 % of primary energy consumption in Germany is for heat generation. To achieve climate neutrality, it is therefore essential to also promote sustainable solutions in this area. Geothermal energy is a promising option that can play a central role as the third pillar in a future sustainable energy system. That is why Tellus Energy Solutions is focusing on combining geothermal energy and natural hydrogen production in the development of the Kairos pilot project in Northern Bavaria.

Potential and Use of Geothermal Energy

Currently, geothermal energy is only used to a limited extent in Germany. An exception is the showcase project of the Stadtwerke München (Munich municipal utilities). Nevertheless, the potential of geothermal energy is estimated to be considerable – far beyond the often cited 25% of Germany’s heating needs. To realize this potential, far-reaching project developments in cities and towns are needed. In addition, expertise in the field of geothermal energy must be expanded. Tellus Energy Solutions sees particular growth potential in the development of decentralized geothermal plants.

One of the key advantages of geothermal energy is its versatile nature. It can be applied in a range of different geological conditions, from shallow geothermal energy to ultra-deep systems, and can cover a broad temperature spectrum. Both closed and open systems are used, which not only provide heat but can also be used for cooling and heat storage. This flexibility makes geothermal energy an attractive solution for a wide range of requirements.

Salt Aquifers: A Key Technology

Saline aquifers in sedimentary rocks offer promising potential for the future development of geothermal energy. These sandstone or carbonate formations in the subsurface are ideally suited for providing low-enthalpy heat for modern fifth-generation heating and cooling networks. Tellus Energy Solutions focuses on the use of these aquifers, combined with the production of hydrogen and/or helium. The synergies between these additional resources contribute to the economic viability of the projects and make geothermal energy an even more attractive source of energy.

Toward Greater Energy Security

Geothermal energy is an almost inexhaustible source of energy. Its expansion is essential for a sustainable heat transition and a energy-secure future. Tellus Energy Solutions is therefore working hard to further develop geothermal solutions in connection with the Kairos pilot project, in order to establish geothermal energy as the third pillar of the future energy system.
