Why hydrogen is needed for green iron production?

Green steel producers are planning to use green hydrogen to decarbonise their steel mills, which together account for 7-8% of all global carbon emissions.Traditionally, iron has been extracted from iron-oxide ore by burning carbon-rich coking coal in a blast furnace, where the fossil fuel produces high-temperature heat while simultaneously removing oxygen from the ore by converting it to carbon dioxide.This highly polluting method can be replaced with green hydrogen in a direct-reduced iron (DRI) facility, where the H2 reacts with the oxygen to produce steam (H2O) rather than carbon dioxide.In fact, hydrogen-based DRI is currently the only proven pathway of decarbonising steel production, when paired with an electric arc furnace powered by renewable energy.Policymakers want producers to eliminate emissions from the sector by using green-hydrogen DRI that is then turned into green steel using renewables-powered electric arc furnaces, but with green H2 costing in excess of €5/kg in Europe, it would result in significantly more expensive steel that will require offtakers to pay a premium.It may therefore be cheaper to produce the green iron in places with stronger winds and sunshine, which would be able to produce cheaper renewable hydrogen.

Hazer should be a better alternative.

The latest edition of Accelerate Hydrogen has a lot of interesting stuff on hydrogen and steelmaking.
