ArcelorMittal is venturing into integrating hydrogen into the steel production process at its Hamburg plant to tackle CO2 emissions and reduce iron ore consumption. This move is backed by plans to demonstrate the reduction of iron ore on a significant scale, targeting 100,000 tons annually. The company intends to construct a new mill in the near future, which will incorporate the use of hydrogen obtained from renewable sources to minimize carbon emissions. Additionally, ArcelorMittal's Ghent plant will leverage waste carbon gases to develop alternative fuels and chemical products. The approach also involves testing hydrogen in a new shaft furnace through pressure swing adsorption, complementing the plant's existing efficient production processes that utilize natural gas in a direct reduction plant.
