HOCLOOP at European Geothermal Congress 2025 marked an important contribution to one of Europe’s leading geothermal research events. The European Geothermal Congress (EGC) 2025, held in Zurich, brought together scientists, engineers, and industry professionals to explore innovations shaping the future of geothermal energy across Europe and beyond.
The European Geothermal Congress serves as a key platform for advancing scientific understanding and practical deployment of geothermal technologies. EGC 2025 placed a strong emphasis on emerging solutions that support the energy transition, including closed-loop geothermal systems and CO₂-based geothermal energy extraction and conversion.
During Session 6B – Science: CO₂-based Geothermal Energy Extraction and Conversion, HOCLOOP partners from the Università degli Studi di Firenze delivered in-depth scientific presentations addressing fundamental challenges in geothermal system performance.
Pietro Ungar presented insights on “the behaviour of working fluid in geothermal systems,” focusing on how fluid dynamics influence efficiency and heat recovery in advanced geothermal configurations. Complementing this work, Federico Gigliotti presented research on “modelling heat transport and thermosiphon flow in closed-loop deep geothermal systems.” His contribution highlighted the importance of accurate thermal and flow modelling for optimizing closed-loop geothermal performance, particularly in deep geothermal applications where subsurface conditions play a critical role.
Beyond the technical sessions, the European Geothermal Congress 2025 fostered collaboration between academic institutions, research organizations, and industry stakeholders. By connecting cutting-edge science with applied geothermal development, EGC 2025 reinforced the role of geothermal energy as a cornerstone of Europe’s sustainable energy future.
HOCLOOP’s participation at EGC 2025 underscores its ongoing commitment to advancing geothermal science and supporting the transition toward low-carbon, renewable heat and energy systems.
