Women in Science in HOCLOOP: Brilliant Experts Advancing Geothermal Innovation
HOCLOOP highlights women researchers advancing geothermal innovation across geology, communication and energy system analysis.
HOCLOOP at European Geothermal Congress 2025 in Zurich
HOCLOOP at European Geothermal Congress 2025 in Zurich featured research on closed-loop geothermal systems, CO₂-based energy extraction, and heat transport modelling.
HOCLOOP at GET 2025 in Rotterdam
Hosted in Rotterdam, Netherlands, GET 2025, the 6th EAGE Global Energy Transition Conference & Exhibition, took place from October 27 to October 31, 2025. And the HOCLOOP was there sharing insights on closed-loop geothermal systems and heat extraction technologies.
HOCLOOP Pilot Test Results Confirm the Potential of Closed-Loop Geothermal Technology
The HOCLOOP project has completed the analysis of its full-scale pilot test at NORCE’s Ullrigg Test Centre. The results confirm that the closed-loop geothermal system delivers stable, predictable heat extraction even in low-permeability environments, strengthening its potential for long-term, sustainable geothermal energy production across Europe.
HOCLOOP joins the 1st Geo-Cluster Workshop on Sustainable Heating and Cooling
HOCLOOP took part in the 1st Geo-Cluster Workshop on Sustainable Heating and Cooling, joining ten Horizon Europe projects advancing geothermal innovation. Watch Hemendra Sharnagat’s presentation “Closed-loop Deep Geothermal Solution” in the full recording.
HOCLOOP General Assembly in Florence: From Innovation to Real-World Application
Two recent workshops in Florence, co-organised by the University of Florence and University of Vaasa, brought together stakeholders and citizens to explore social and business perspectives on closed-loop geothermal energy within the HOCLOOP project.
