SSAB, LKAB and Vattenfall have commenced construction of a rock cavern storage facility for fossil-free hydrogen gas next to their pilot HYBRIT facility for direct reduction in Luleå, Sweden.
Announcing the news today (7th April), construction of the 100 cubic metre hydrogen storage facility in Svartöberget is set to help with the demands of the steelmaking process by developing the technology for hydrogen storage.
Uniquely, the hydrogen storage is being built in an enclosed rock cavern approximately 30 metres below ground and will be achieved through a technique called LRC (Lined Rock Cavern) which means that the walls of the cavern will be covered with a carefully selected material as a sealing layer.
Building the storage facility in an underground enclosure provides opportunities to ensure the pressure required to store large amounts of energy in the form of hydrogen in a cost-effective way.
