"We want to develop HYBRIT so that it is in line with the electricity system of the future, with more weather-dependent electricity generation. The storage facility is unique and once again the HYBRIT initiative is taking the lead in the fossil-free transition. HYBRIT is very important for facing the climate challenge and enabling fossil-free living within one generation," says
"SSAB has the opportunity to transform our operations and cut 10% of
"Hydrogen gas and its storage are central to our transition. In four years, HYBRIT technology will be used on a large scale in the first demonstration plant in Gällivare, and the plan is to then build more sponge iron factories.
"The pilot plant is important in order to really test and understand how large-scale hydrogen storage works. Storage of hydrogen gas will be an important piece of the puzzle for a fossil-free value chain for the iron and steel industry, but also in a future robust electrical system," says
The technology for storing gas in a lined rock cavern (LRC) is well proven and has been used in southern
The pilot plant has a size of 100 cubic meters. At a later stage, a full-scale hydrogen gas storage facility measuring 100,000 to 120,000 cubic meters may be required, in which case it will be able to store up to 100 GWh of electricity converted to hydrogen gas, which is sufficient to supply a full-sized sponge iron factory for three to four days.
Using HYBRIT technology, SSAB can reduce
Facts about the hydrogen gas storage facility:
- Construction of the hydrogen gas storage facility began in
May 2021 . Hydrogen storage will be tested in the storage facility using known technology known as LRC (Lined Rock Cavern). This means the gas is stored underground in a rock cavern whose walls are lined with a selected material as a sealing layer. - The fossil-free hydrogen gas is produced by water electrolysis using fossil-free electricity.
- It's important to build in rock of a type that maintains its good qualities. For example, the bedrock in Svartöberget consists mainly of amphibolite with elements of pegmatite and red granite.
- The rock cavern in Svartöberget where the gas is stored is about 30 meters below ground level and 100 meters from the entrance.
Facts about the HYBRIT project:
- With the HYBRIT initiative, SSAB,
LKAB andVattenfall intend to create a completely fossil-free value chain from mine to finished steel, with fossil-free pellets, fossil-free electricity and hydrogen. - HYBRIT technology replaces the blast furnace process, which uses coal to remove oxygen from the iron ore, with a direct reduction process that uses fossil-free hydrogen gas. Instead of carbon dioxide, the by-product turns into water.

The pilot plant for the production of sponge iron in Luleå was commissioned on
31 August 2020 and the next step is planned for 2026 with a demonstration plant for the production of fossil-free sponge iron on an industrial scale in Gällivare. -
In
August 2021 , SSAB produced the world's first fossil-free steel, produced using HYBRIT technology, and delivered to the customer.
