About Sponge Iron. Direct-reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture, the majority of which is hydrogen (H2) and carbon monoxide (CO), which act as reducing agents.

Steel making contributes 6% of global CO2 emission (including associated power emissions). Blast furnaces dominate global production, have long capital lives, and resist adoption of decarbonization technology. Deep decarbonization and net-zero production will require both asset replacement from BF to DRI+EAF and development …
