HYBRIT – A Swedish National Development Project for Fossil Free Steel

The Swedish steel industry has a strong position in terms of efficient blast furnace operation and CO2 emission. This is result of a successful development work carried out in the 1980’s at LKAB and SSAB followed by closing of sinter plants and transition to 100% pellet operation at all SSAB’s five blast furnaces. SSAB is today the steel company with lowest carbon dioxide emission per ton hot metal produced by the blast furnace process. Pilot plant trials within the ULCOS project carried out at LKAB’s experimental blast furnace at Swerea Mefos in Luleå Sweden showed that modifying the blast furnace with top gas recirculation combined with CCS, a reduction of approximately 50% CO2 emission is achievable.

To drastically reduce CO2 emission further breakthrough technology is necessary to replace the blast furnace process for ironmaking. On April 4th 2016, SSAB together with LKAB and Vattenfall launched a project aimed at investigating the feasibility of a hydrogen based sponge iron production process, with CO2 emission free electricity as the primary energy source – HYBRIT (Hydrogen Breakthrough Ironmaking Technology).
Sweden has a unique opportunity for research and development for the HYBRIT project:

• A long tradition of developing iron ore reduction technologies
• A steel industry specialized in high end products requiring clean raw material
• A leading iron ore mining industry delivering advanced BF- and DR-pellets
• A fossil-free electricity system with excess capacity
• A suitable R&D environment with universities, research institutes and efficient coordination through branch organizations
• A nation with high ambition to drastically reduce CO2-emissions
