Green Hydrogen‐Based Direct Reduction for Low‐Carbon

13 05 2020  The oxygen from the iron ore reacts with the reducing gas mainly composed by a mixture of CO and H 2 at elevated temperatures to produce metallic iron while releasing CO 2 and H 2 O The heat required for the endothermic reduction with hydrogen is supplied by the energy released from the exothermic reaction between carbon monoxide and iron oxides.

Energy Use in US Steel Manufacturing

As high quality iron ore reserves run out lower iron content ore will need to be processed to create steel This may raise energy requirements in the future and could raise costs For there to be any appreciable difference in the costs of production between energy sources we will need to see a divergence in the cost per joule.
