A hydrogenbased direct reduction of iron ore (DRI) and steel scrap melting in an electric arc furnace (EAF) appeared to be the most mature technological routes to date, capable of reducing CO 2 emission by 95% but rely on the availability of rich iron concentrates as feed materials. Shaft furnace technologies are the common DRImaking process ...

One cleaner way to produce steel uses direct reduced iron, or DRI, in which ore is reduced with hydrogen and carbon monoxide. If global steelmaking follows a path to netzero emissions by 2050, demand for direct reduced, or DRgrade, iron ore could rise tenfold, IEEFA Energy Finance Analyst Simon Nicholas said.
