GeoTHERM 2025: From Europe's largest trade fair to the world's leading trade fair for geothermal energy
Offenburg. GeoTHERM expo & congress 2025 has impressively demonstrated why it is now regarded as the world's leading trade fair for geothermal energy. On 20 and 21 February, the international industry event once again attracted experts, companies and decision-makers from all over the world - with an increase in visitor numbers of around 30%. A total of 8,522 visitors took part in this year's GeoTHERM (previous year 6,509). This dynamic growth underlines the central role of GeoTHERM in the global geothermal sector.
„GeoTHERM 2025 experienced an unprecedented level of internationality,“ says exhibition director Frank Thieme. „This year, we welcomed 280 exhibitors from 23 nations - including Australia, China, Japan, Canada, the United Arab Emirates and the USA. This impressive diversity shows that geothermal energy has long been a global topic and that GeoTHERM offers a crucial platform for international dialogue“
But it's not just the internationality that is setting new standards - the companies' presentations are also becoming increasingly impressive. „Our exhibitors are increasingly bringing large-format exhibits with them,“ explains project manager Gabriele Weislogel. „From drilling rigs for near-surface geothermal energy to state-of-the-art measuring trucks for seismic measurements and innovative storage systems - GeoTHERM 2025 was a real experience for the trade visitors.“
A particular highlight was the newly created Start-Up Area, which served as the trade fair's innovation hub. Young, dynamic companies with pioneering technologies and solutions presented themselves here. The Start-Up Area quickly developed into a hotspot for networking and investment: In the direct neighbourhood of established market leaders, up-and-coming companies were able to make valuable contacts with investors, business partners and mentors.
„With over 60 top-class presentations, the scientific congress at GeoTHERM 2025 offered a concentrated load of expertise,“ emphasises Tanja Hartmann, Head of Trade Fairs. „The combination of near-surface and deep geothermal energy in particular made the programme unique and impressively demonstrated the wide-ranging potential of this technology.“
The next GeoTHERM expo & congress will take place in Offenburg on 26 and 27 February 2026.
Venue and organiser: Messe Offenburg, Schutterwälder Str. 3, 77656 Offenburg.
