The use of green hydrogen would make it possible to completely decarbonise the process, since it would only produce water vapour as chemical by-product. Through the iron ore reduction process: (Fe2O3 + 3H2 → 2Fe + 3H2O), iron (Fe) is produced together with water (H2O), and this iron is called Direct Reduced Iron (DRI). DRI is finally reduced ...
