The European Geothermal Energy Council has announce five endorsed nominations for the Ruggero Bertani European Geothermal Innovation Award 2025.
The winner will be declared at GeoTHERM expo & congress, set to be held on 20 and 21 February in Offenburg, Germany.
“We extend our heartfelt congratulations to the five exceptional nominees for the Ruggero Bertani European Geothermal Innovation Award 2025. These pioneering projects exemplify the innovation, ingenuity, and commitment needed to drive geothermal energy forward as a cornerstone of sustainable energy systems in Europe and beyond. Each finalist has contributed groundbreaking solutions that highlight the potential of geothermal technology to address pressing global energy challenges,” said Philippe Dumas, EGEC Secretary-General.
The finalists this year include EnBW Energie Baden-Wuerttemberg AG, Halliburton, iSOR – Iceland GeoSurvey, Mines Paris-PSL University and Qheat.
EnBW's Cascade addresses several intricate challenges involved in the process of lithium extraction from geothermal brines. It features a second reactor with a Ti-/Mn-based adsorbents to recycle the process of water, while also considerably eliminating energy and transportation costs, distinguishing it from standard technologies.
Halliburton's Truesync PMM: Geothermal Electric Submersible Pump (GeoESP) Motor stands out for its hybrid design that packs in advanced features along side those of traditional induction motor technology. The tool is flexible in compatibility with variable speed drives (VSD) from different suppliers.
iSOR's flexible coupling technology address casing failures in production casings of high-temperature geothermal wells, in cases of constrained thermal expansion. The tool gives space to the casing to expand into the connection without any kinds of pressure that might leave permanent plastic strain.
Orchyd by Mines Paris-PSL University boasts of advanced penetration rates when it comes to drilling deep geothermal wells. It comes especiaccly handy in drilling hard crystalline rocks like granites that lie deeper than 4km.
QHeat's innovative geothermal solution that is applicable for heating as well as cooling is installed in a waste-to-energy facility in Finland. Designed to reach geothermal depths of up to 2000 m, the tool features Coaxial Reversible Medium-Deep Geothermal Heat Wells (MDGHWs).
