Sweden’s Hybrit, a collaboration between energy company Vattenfall, steelmaker SSAB, and mining company LKAB, has successfully completed a pilot hydrogen storage project. The company stated that the project results demonstrated the technical feasibility of storing hydrogen for fossil-free steel production on an industrial scale.

The test results confirmed that the technology can effectively support a large hydrogen user while reducing production costs by approximately 25-40%.

The pilot storage facility has also undergone accelerated mechanical testing, simulating around 50 years of operation. Based on these results and the experience gained from the pilot project, the technology is now ready for commercialization.
