Hmmm I heard of studies/prototyping/research to completely overhaul steel production in order to reduce the (gigantic) carbon footprint. It might be linked?
Not just heating it differently, really change the process… Searching for source, will update.

Using hydrogen instead of coal, not for heating but for the reaction actually creating iron. I remeber reading about rotating furnace, like the one used to create cement.
Babis is known to have done that for years, using his government position to facilitate it.
I’m so glad he was kicked out of the government, but I don’t know if anything happened to him since. Probably not.
