Iron ore + hydrogen = Iron + water. It's used to tear oxygen off the ore, currently that's done with carbon, generally of fossil origin. thyssenkrupp is already doing it at scale. Not all the hydrogen they use right now is green but unlike the old furnaces the new ones are ready to be carbon-neutral, they just have to switch over fuel sources no need to mess with the furnaces themselves.

It is possible to do the reduction directly with electricity but that's less energy-efficient than going via hydrogen. For the chemical industry the situation is even more extreme they need hydrogen as an ingredient for the final product, not just as a reactant.
