The largest contributions are from iron ore pelletization, followed by NG supply and coal mining supply chains (for more details, refer to in the Supplementary Material). The coal gasifier and NG reformer DRI processes use iron ore pellets (67% Fe) compared to the rotary kiln process that uses lump ore (% Fe).

A shortage of highquality iron ore in the marketplace presents a significant hurdle for steelmakers who are trying to reduce their carbon emissions. Green hydrogenbased technologies use less carbon to produce steel, but the process requires higher iron ore grades than traditional blast furnaces. A dearth of ore with an iron content above 65% ...
