Geothermal Innovation Days 2026 & Knowledge Sharing Workshop

On 13-14 October 2026, the Geothermal Innovation Days and Knowledge Sharing Workshop brought together geothermal experts, researchers, industry representatives and policymakers at TU Delft, the Netherlands, for two days of knowledge exchange, innovation and networking.

The events provided a platform to explore the latest geothermal technologies, European funding opportunities, research collaboration and pathways to bring innovative solutions to market. The Knowledge Sharing Workshop also showcased results from European research and innovation projects.

The event was organised in collaboration with ETIP-Geothermal, CETPartnership, the GEOTHERMICA Initiative, the Netherlands Enterprise Agency and the Smart Energy Systems ERA-Net.

PRESENTATIONS ARE NOW AVAILABLE!
