Green steel at its crossroads: Hybrid hydrogenbased reduction of iron ...
Iron and steelmaking cause ∼7% of the global CO 2 emissions, due to the use of carbon for the reduction of iron carbon by hydrogen as the reductant offers a pathway to massively reduce these emissions. However, the production of hydrogen using renewable energy will remain as one of the bottlenecks at least during the next two decades, because making the gigantic annual crude ...
