Following the June inauguration of HYBRIT’s pilot rock cavern hydrogen storage facility, initial pressure tests with water confirmed the facility's mechanical stability, tightness and pressure capacity.
The technology for the storage of gas in an underground lined rock cavern (LRC) involves the cavern walls being lined with a sealing layer. LRCs have been thoroughly tested with natural gas, but the pilot facility in Luleå is the first in the world to test the technology with repeated filling and emptying of hydrogen gas.
The pilot facility’s size is 100 m3, and at a later stage it may be necessary to keep 100,000 to 120,000 m3 of pressurised hydrogen gas in a full-scale storage. This means that up to 100 GWh of electricity in the form of hydrogen gas could be stored, which is enough to supply a full-size sponge iron factory for about three to four days.
