Vast storage potential in northern Germany

-

A successful ramp-up of the hydrogen market would be impossible without a means of hydrogen storage, and salt caverns are ideally suited to the task. These artificial cavities, more than 1,000 meters (3,200 feet) deep in salt rock, can be primarily found in northwestern Germany. While previously they have contained fossil fuels such as crude oil and natural gas, in the future they are set to hold hydrogen.
