H2CAST Etzel
Making energy transition work.
About the project
The H2CAST Etzel project is intended to demonstrate the feasibility of large-volume underground storage of hydrogen and to prove the suitability of the salt caverns in Etzel for hydrogen storage. Operational hydrogen storage operations will be tested and serve to build a hydrogen service industry. H2CAST stands for H2 CAvern Storage Transition, i.e. the conversion of existing caverns and facilities in Etzel for the future necessary storage of hydrogen as a building block for a future energy system.
