HYBRIT Proves Large-Scale Fossil-Free Hydrogen Storage Feasibility

Project Overview

The HYBRIT initiative, started in 2016 by SSAB, LKAB, and Vattenfall, aims to create the world's first fossil-free iron and steel production using hydrogen gas and fossil-free electricity. The project focuses on producing fossil-free sponge iron and has now successfully completed a pilot for hydrogen gas storage.

Hydrogen Storage Facility

A 100 m³ hydrogen storage facility was constructed in Svartöberget, Sweden, using steel-lined rock cavern technology. The facility supports large-scale hydrogen use and has demonstrated potential savings of 25-40% in variable operating costs. The pilot facility underwent accelerated mechanical testing equivalent to 50 years of operation, proving its safety, functionality, and performance.

Economic and Environmental Impact

The project shows that large-scale storage of fossil-free hydrogen is both technically feasible and economically beneficial. By optimizing hydrogen production based on electricity market fluctuations, the facility can reduce production costs significantly. The technology is ready for industrial scaling, with the potential to drastically reduce the climate footprint of the iron and steel industry.

Future Prospects

The Swedish Energy Agency co-financed 22% of the hydrogen storage project. The successful pilot results provide a strong foundation for future decisions on hydrogen storage, supporting the transition to fossil-free industrial processes. The HYBRIT project plans to extend the pilot until 2026 to conduct further tests and improve conditions for commercial hydrogen storage design.
