are pleased to invite you
to their joint event



UNDERGROUND H2 STORAGE
Enabling Europe's Hydrogen future
through large-scale storage
European Hydrogen week
Brussels Expo, Belgium
(Hall 11- 3rd Floor)
REGISTER FOR THE EVENT
As this is a side event of the European Hydrogen Week, please note that it is therefore necessary that you also register for it:
REGISTER FOR THE EU H2 WEEK






The European projects FrHyGe and EUH2STARS are demonstrating two key pathways for Underground Hydrogen Storage (UHS) in Europe. While FrHyGe focuses on hydrogen storage in salt caverns, EUH2STARS is developing underground hydrogen storage solutions in depleted natural gas reservoirs.

These two complementary approaches are expected to play a crucial role in Europe’s future energy system (e.g., energy resilience, security of supply and competitiveness).

Taking place within the European Hydrogen Week 2026, the event will bring together leading experts, policymakers, industry representatives and project partners to exchange knowledge and discuss the deployment, operation and integration of underground hydrogen storage across Europe.



We look forward to your participation and to an engaging exchange with you!
