Sweden’s Hybrit initiative will present the results of six years of research into fossil-free direct reduced iron-making technology in a final report to the Swedish Energy Agency, Kallanish learns from SSAB, a partner in the project.
Hybrit is a collaboration between SSAB, mining company LKAB and energy company Vattenfall, which have received several patents based on the results. The project is now continuing in the next phase where the process is to be implemented on an industrial scale.
The pilot phase resulted in the development of a new hydrogen-based technology for efficient fossil-free iron and steel production with 0.0 tonnes of CO2 emissions per tonne of steel. It also developed a new fossil-free iron product – sponge iron – that has significantly better properties than iron reduced with fossil gases such as natural gas. It also produced an efficient process practice for melting fossil-free sponge iron into crude steel in an electric arc furnace.
The project is the first in the world to demonstrate that the fossil-free value chain – from iron ore to steel – works on a semi-industrial scale. So far, more than 5,000 tonnes of hydrogen-reduced iron have been produced at the pilot plant in Luleå. Customers such as Volvo, Epiroc, Peab and many more are already using the fossil-free steel in vehicles, heavy machinery, buildings and consumer products.
