Storing Hydrogen in Underground Salt Caverns

Hydrogen Storage

Pioneering the underground hydrogen scene

For bulk storage of very large amounts of gaseous hydrogen, underground salt caverns are an option. The gas has to be purified and compressed before it can be injected into the cavern. Hydrogen-filled cavities can act as a backup for a pipeline network.

Linde has been operating the world’s first commercial hydrogen high-purity cavern for over a decade and we supply some of our pipeline hydrogen customers out of this hydrogen storage facility in Texas. The underground storage cavern is designed to provide our customers with hydrogen during periods of planned and unplanned peak demand. The storage facility is integrated into Linde’s 310-mile (498 km) hydrogen pipeline that serves more than 50 refineries and chemical plants from Texas City, Texas, to Lake Charles, Louisiana.

Linde’s Gulf Coast pipeline network has the capability of supplying 600 million cubic feet per day (16 million cubic meters per day) of hydrogen on a steady-state basis, with peak capacity of 700 million cubic feet per day (18 million cubic meters per day).
