The Offenburg show attracted 8,688 trade visitors and 302 exhibitors in 2026, bringing drilling companies, project developers, energy suppliers, local authorities and researchers together around the heat transition. Its distinguishing feature is the combination of a commercial exhibition with parallel congresses on shallow and deep geothermal energy.
That split makes the event useful at very different project scales. Building and neighborhood heating sits alongside exploration, deep resource development, storage and heat utilization. The scientific program accepts practical projects as well as research, while excluding pure product pitches. International guest delegations add another layer: the 2027 program brings French, Icelandic and Scottish experience into a discussion that now extends to mine water, existing oil and gas infrastructure, and sector coupling. Offenburg is especially relevant to teams connecting subsurface engineering with municipal heat supply.
How it compares

- Geothermal Rising ConferenceReno
European Geothermal Congress is the more concentrated forum for European policy, finance and research across power, heat, storage and mineral extraction. Its technical sessions sit alongside workshops, training and site visits. Held every three years, it gives a geothermal team a reason to step back from individual equipment choices and consider deployment, regulation and the wider market. GeoTHERM provides the annual supplier encounter, with shallow and deep geothermal congresses supporting the exhibition.
Geothermal Rising Conference puts a company closer to the US geothermal community. Its 2027 host, Reno, places the meeting in a state with an established geothermal industry, and the Peppermill venue itself uses geothermal heating. That makes it a useful alternative for firms developing American relationships or discussing power projects with US partners. GeoTHERM is the more direct fit for European heat networks, drilling services and building-scale applications.
For a utility, municipality or engineering firm, the choice depends on the work ahead. European Geothermal Congress supports the policy and research conversation; Geothermal Rising Conference supports entry into the American network. GeoTHERM lets a team connect project problems with suppliers while keeping the shallow and deep technical tracks within the same trip.
GeoTHERM is the right trip for teams turning geothermal engineering into European building heat, heat networks and operating projects.
Who exhibits
The exhibition covers drilling rigs and equipment, well contractors, heat exchangers, backfill materials, geophysics, software, pumps and plant engineering. That breadth connects the underground resource with the equipment and services needed to use it. The 2027 guest stands bring Scottish Enterprise, France’s A.F.P.G. and ORKIS Energy Cluster Iceland into the exchange, adding mine-water heating and established geothermal markets to the supplier discussion.

GeoTHERM Expo & Congress 2027
GeoTHERM 2027 marks the show’s 20th anniversary with guest countries Iceland, Scotland and France. Their delegations will contribute to the opening session as well as joint stands. The scientific focus on sector coupling connects geothermal projects with oil, gas, mining and other energy infrastructure. Mine-water heating adds a practical Scottish perspective, while the shallow and deep congresses continue to cover applications from buildings to larger energy projects.
- Bring headphones and a charged smartphone for LiveVoice translation into German, English or French; the event ID is supplied on site.
- For mine-water heat and cross-border projects, include the Scottish, French and Icelandic guest stands in your route between the two geothermal congress tracks.
Exhibiting
The international Start-Up Area supplies a furnished row stand for young companies based outside Germany, while the Young Innovators route addresses eligible German businesses. Keep the two schemes distinct when applying. The scientific congress requires technical or scientific value, so product demonstrations belong on the stand and research findings in a paper submission.
