- Another milestone in the conversion of existing caverns for the use of hydrogen in Etzel has been realised as planned
- Introduction of the first tranche of 90 tonnes of hydrogen in total
- STORAG ETZEL: ‘The existing caverns in the Etzel cavern field are suitable for hydrogen storage’
- STORAG ETZEL: ‘We are continuing to pursue our hydrogen storage strategy. The Etzel caverns are scalable and flexible, meaning that existing underground gas and oil storage facilities here can be repurposed for the use of hydrogen.’
Following the successful completion of the conversion and leak tests with hydrogen in two caverns in 2024, STORAG ETZEL began injecting the first quantities of a planned total of 90 tonnes of hydrogen at the turn of the year. The injection is part of the ‘H2CAST Etzel’ research and development project, which is developing the technical implementation of hydrogen storage in salt caverns. ‘This represents another milestone in the conversion of existing caverns for the storage of hydrogen in Etzel,’ says Carsten Reekers, project manager of the “H2CAST Etzel” research and development project.
The gaseous hydrogen delivered at a pressure of 300 bar by truck trailers displaces the brine from the caverns during storage via the cavern head and borehole piping suitable for hydrogen. The brine is transported away via the STORAG ETZEL brine system.
