Uh, can you provide any scientific papers that H2 can be used for Iron smelting? CO2 is very stable, even at high temperatures. Its hard to strip O2 from it (except photosintesis). Now, H2 itself is very violatile gas. When burn, it creates water. Water is not stable high temperatures. It become vapor and when temperature rise it can even break bond between H2 and O.

So, papers or are you hallucinating?

They are already building such plants. So I would assume they have a plan

But here is a paper - only the title is German the main part is English https://pure.unileoben.ac.at/files/1851525/AC06514880n01vt.p...

See https://en.wikipedia.org/wiki/Steelmaking#Hydrogen_direct_re... and linked sources.

Are you suggesting burning H2 will create water and enough energy to split the water in H2 and oxygen again, afterwards? That would be amazing news!

No, not at all. Coke or hydrogen always only provide additional heat, they are never the main source of heat. The main heat source can either be coal or an electric arc furnace. The coke or hydrogen are just necessary for the chemical reaction, and providing some heat is a side-effect.
