Germany’s EWE trials underground hydrogen storage
Pilot project could open the door to large-scale deployment
German utility EWE is constructing a pilot project to test the safety of storing pure hydrogen in underground salt caverns with a view to deployment on a large scale as production of the gas ramps up. EWE is working with the German Aerospace Center (DLR) on the project, which is expected to cost around €10mn ($11.9mn), of which EWE is providing €4mn. Findings from the project could be transferred to large cavern storage facilities, according to EWE hydrogen specialist Paul Schneider. “This would mean that large quantities of green hydrogen generated from renewable energies could be stored and used as needed,” he says. The rock salt layer at the storage site in Brandenburg, Germany begins a
