Modern DRI plants are technical ready and capable to support such a transition away from coal towards natural gas and subsequently hydrogen. Although a pure hydrogenbased shaft furnace direct reduction process in a large scale has not been realized yet the concept is technically feasible and has been proven for hydrogenrich operation modes.

Rio Tinto and other steel and mining groups have highlighted the need to adapt processes for DRI plants which have traditionally run on reformed natural gas as new plants are developed for hydrogenbased reduction. Many such projects expect to create hydrogen for DRI with electrolysis using renewable power from wind and solar projects.

The MXCOL technology combines a gasification plant and MIDREX shaft furnacebased DRI plant capable of producing steel with lower capital cost than integrated steel manufacturing (Hasanbeigi et al., 2013). The offgas from the DRI plant is recycled with fresh syngas after removing CO 2 using a scrubber (MxColUsing Syngas to make DRI, 2014).
