HYBRIT: Large-scale storage of fossil-free hydrogen gas successfully proven

Sweden-based HYBRIT has successfully completed a pilot project for large-scale storage of fossil-free hydrogen gas, reporting the results to the Swedish Energy Agency. The project, initiated by SSAB, LKAB, and Vattenfall, aims to develop fossil-free iron and steel production using hydrogen gas. The pilot demonstrated the feasibility of storing hydrogen gas in a 100 m3 steel-lined rock cavern, achieving savings of 25-40% in variable operating costs. The technology is now ready for industrial scaling, potentially reducing Sweden’s and Finland’s carbon dioxide emissions by 10% and 7%, respectively.
