Geothermal energy in Mannheim: Future of district heating or risk for citizens?

Geothermal energy is the focus of a heated debate in Mannheim, where citizens are wondering whether this technology is a safe and sustainable solution for the city's district heating supply or whether it is too risky. These questions were recently discussed at a panel discussion of the Lindenhof (BIG) citizens' interest community, in which top-class experts took part, including Dr. Andre Baumann from the Ministry of the Environment and Member of the Bundestag Konrad Stockmeier. According to a report by Wochblatt-Reporter the event was well attended and offered those present the opportunity to express their concerns and to receive answers to pressing questions.

A central topic of the discussion was the current state of soil investigations that were carried out for the identification of suitable locations for geothermal meadows. Stefan Ertle, Managing Director of Geohardt GmbH, presented a promising 3D picture of the potential area, which extends from the SAP-Arena to Oftersheim. A total of 70 km² was examined, with water protection areas being excluded. The first drilling could begin in 2028, but up to 30 permits are required before starting. Security has a top priority.

risks and safety precautions

The discussion about the security of the geothermal energy was intense. Dr. Jürgen Hammer from the city of Mannheim emphasized that the risk in Mannheim was extremely low due to the hydrothermal geothermal energy, which works with little pressure. In contrast to Petrothermic methods that require high pressures, a pressure of only 80 to 100 bar is worked here. In addition, a comprehensive surveillance system with sensors is installed in order to identify potential problems at an early stage.

Another important point was the liability insurance of the operators, which covers up to 20 million euros per drilling point in the event of damage. If this is not enough, the mountain damage loss fund will take another 17.5 million euros. These regulations are part of the efforts to strengthen the trust of citizens in geothermal energy and to minimize possible risks.

draft law to accelerate the approval process

Geothermal energy is viewed as a climate -neutral and reliable source of energy, which is able to cover high heat. Nevertheless, there are concerns about the possible competition with other water uses, such as drinking water, which also heats up the discussion about geothermal energy. Experts call for a comprehensive consideration of all aspects to ensure the security and sustainability of this technology.

Finally, it can be said that the geothermal energy in Mannheim is on the test. The coming months will be crucial to clarify whether this technology is actually a future -proof solution for the city's heat supply or whether the risks outweigh. The citizens are called to continue to actively contribute and raise their votes, while politics is working on solutions that ensure both security and sustainability.
