Direct hydrogen reduction has been there for a while. The only issue is cost.

  Energy intensity is an issue with hydrogen steelmaking. To produce hydrogen by electrolysis at the large scale needed for steelmaking requires a massive amount of electricity. Ideally it needs to be green electricity as well. So if there is a lower energy way of producing green steel it is at least worth exploring.

    What are you suggesting, electrolysis baths in every solar-powered home? Meaningful solar, hydro, nuke and wind power plants are quite concentrated (100MW-few GW) anyway. If anything, solar/wind are less suitable due to intermittent output and would require hydrogen buffer storage.
