Arcelor Mittal looks to develop a low emissions technology
To permanently reduce CO2 emissions, steelmaker ArcelorMittal has developed a low-emissions technology strategy, which targets not only the use of alternative feedstocks and the conversion of CO2 emissions, but also the direct avoidance of carbon (Carbon Direct Avoidance, CDA).
This year, the Group intends to launch a new project in the ArcelorMittal plant in Hamburg to use hydrogen on an industrial scale for the direct reduction of iron ore (H-DR) in the steel production process for the first time. (DRI is iron ore that has been reduced to iron with without melting.) A pilot plant is to be built in the coming years.
The Hamburg plant already has one of the most efficient production processes of the ArcelorMittal Group due to the use of natural gas in a direct reduction plant (DRI, direct reduced iron). The aim of the new hydrogen-based process is to be able to produce steel with the lowest CO2 emissions.
The project costs amount to around €65 million (US$73 million). In addition, a cooperation agreement with the University of Freiberg is planned to test the procedure in the coming years at the Hamburg plant premises. The hydrogen-based reduction of iron ore will initially take place on a demonstration scale with an annual production of 100,000 tonnes.
