Praxisforum Geothermie.Bayern 2025 will feature MTU’s geothermal plant and Grünwald’s bid for 100% geothermal heat as flagship project visits.
The upcoming Praxisforum Geothermie.Bayern, October 22-24, 2025 will close with a field visit to two major projects that underscore the growing role of deep geothermal energy in Bavaria.
MTU Aero Engines’ geothermal system
The first stop of the “GeoTHOUR” on 24 October will be the newly built geothermal facility of MTU Aero Engines AG in northern Munich. The DAX-40 company is the first of its kind in Germany to implement a deep geothermal project. Once fully operational, the plant is expected to replace up to 80% of the site’s natural gas demand for heating. The facility will shift from test operation to regular use later this year, serving as a model for industrial decarbonisation.
Grünwald aiming for 100% geothermal heat
The second highlight is the new drilling site of Erdwärme Grünwald GmbH in the south of Munich district. Building on its existing plant, the municipal utility aims to cover the entire heat demand of Grünwald’s 11,000 residents with renewable geothermal energy. If successful, the town will become the first municipality in Germany with a 100% geothermal heat supply.
About the event
The Praxisforum Geothermie.Bayern, held 22–24 October 2025, brings together professionals, policymakers, and industry players. The program includes workshops, a conference day on challenges and developments, and concludes with the “GeoTHOUR” site visits.
Event organizer Jochen Schneider described the two projects as “examples that will excite anyone committed to a successful heat transition.” For further coverage on Germany, see our news overview page.
