Today’s steel making landscape with large blast furnaces and mega module sponge iron production in multimillion tonne per year scale has been made possible by continuous improvement over decades and the ease by which we transport ore and coal over the oceans and have access to piped natural gas.
This order is now challenged by two winds of change: (1) a new generation of processes with lower footprint and (2) regionalisation creating a more resilient supply chain. Alternative reduction processes need either large volumes of electricity to produce hydrogen or large volumes of biomass to produce biogenic syngas. Grid capacity and biomass logistics will no doubt limit the size of each plant. Furthermore, scaling up new technology takes time and will also limit the production on each site.
