The GeoTHERM expo & congress, Europe's leading trade fair and congress for geothermal energy, is held annually in the spring at the Offenburg Exhibition Centre. Since its inception in 2007, the event has established itself as a central meeting point for professionals and enthusiasts in the field of geothermal energy. It is organized by Messe Offenburg-Ortenau GmbH, known for creating platforms for the exchange of expertise and the presentation of innovations. Geothermal energy, which harnesses the heat stored within the Earth, is at the forefront of GeoTHERM. This renewable energy source offers the potential to make a significant contribution to energy supply by providing a clean, sustainable, and largely independent alternative to fossil fuels. The fair covers both shallow geothermal energy, used for heating and cooling systems in buildings, and deep geothermal energy, utilized for industrial-level power and heat generation. GeoTHERM provides a unique platform for comprehensive information on project experiences, current developments, and future technologies in the realm of geothermal energy. Exhibitors showcase their latest products and services, while two parallel congresses offer in-depth information on both aspects of geothermal energy. The event attracts a wide audience, including energy companies, architects, craftsmen, geologists, developers, and other professionals interested in utilizing geothermal resources. A highlight is the presentation of innovative solutions and technologies that help to improve the efficiency and economic viability of geothermal energy use. The venue, Offenburg Exhibition Centre, is strategically located in the tri-border area of Germany, France, and Switzerland, making it an ideal meeting point for participants from various countries. The modern exhibition halls provide excellent infrastructure for exhibitors and visitors, including ample exhibition space, conference rooms, and catering areas. Messe Offenburg-Ortenau GmbH, as the organizer, places great emphasis on the sustainable execution of GeoTHERM, underscoring the fair's significance in the context of promoting renewable energies. Overall, GeoTHERM expo & congress represents an important platform for exchanging knowledge, expanding networks, and advancing the development of geothermal energy as a viable future energy source. The GeoTHERM will take place on 2 days from Thursday, 26. February to Friday, 27. February 2026 in Offenburg.
