Decarbonization of the Iron and Steel Industry with Direct Reduction of Iron Ore with Green Hydrogen
Energies, 2020 Production of iron and steel releases seven percent of the global greenhouse gas (GHG) emissions. Incremental changes in present primary steel production technologies would not be sufficient to meet the emission reduction targets. Replacing coke, used in
