Rock cavern hydrogen storage pilot inaugurated in Sweden

SSAD, LKAB and Vattenfall announced on Tuesday (June 14) they were inaugurating HYBRIT’s pilot rock cavern hydrogen storage facility at Svartöberget, in Luleå, Sweden.

The 100 cubic metre storage facility, said to be the first of its kind in the world, is set to be tested for two-years with a goal of contributing to the value chain for fossil-free iron and steel production.

H2 View understands, the facility could be scaled to 120,000 cubic metres, storing up to 100GWh of electricity converted to hydrogen gas, which the companies say could power a full-sized sponge iron factory for three to four days.

Sponge iron is the basis of steel manufacturing. Produced through the reduction of iron ore to metallic iron through reaction with carbon at high temperatures Typically processed coal, hydrogen can be used to dramatically reduce emissions in the process.
