ULCOS (Ultra Low CO2 Steelmaking) is the world's most ambitious R&D initiative to reduce carbon dioxide emissions from steel production by developing new breakthrough technologies.Bothe Tata Steel and Arcelor Mittal are core partners in this consortium funded mostly by EU.
Tata Steel and Rio Tinto have signed a licensing agreement to further support technological and commercial development of the environmentally friendly direct iron smelting process called HIsarna™. HIsarna (an old Celtic word for iron) is a new technology under development by ULCOS. It is a highly energy efficient ironmaking process based on direct smelting of iron ore fines using a smelt cyclone in combination with a coal-based smelter. All process steps are directly hot-coupled, avoiding energy losses from intermediate treatment of materials and process gases. The HIsarna™ ironmaking process consists of cyclone pre-reduction technology (CCF), owned by Tata Steel, and bath smelting technology (HIsmelt) owned by Rio Tinto. This combination offers excellent opportunities for the collection and geological storage of CO2, the ability to utilise lower-cost raw material feeds, and the prospect of energy savings through the elimination of stages in the ironmaking process that are necessary today. The technology has the long-term potential to replace conventional blast furnaces, coke ovens and sinter plants and to reduce CO2 emissions by more than 50% if combined with Carbon Capture and Storage (CCS).
ArcelorMittal is pursuing carbon dioxide (CO2) capture, transport and storage project in the Lorraine region. Following its capture, the CO2 will be transported in a buried pipe to be stored inside geological layers offering the properties and guarantees required for very long term confinement without risk for health or environment. The storage layers under study are saline aquifers at a depth of more than 1,000 meters.
