You *could* electrowin steel; there isn’t any sort of thermodynamic rule against it I don’t know if anyone has developed such a process, but there is an interesting cycle that takes in methane, iron ore, and electricity, and outputs high-purity iron, medium-chain aliphatic hydrocarbons, and water

There’s a very good Volts episode about a candidate process for steel production overcast.fm/+AAoT_mtoyKo

Most of the discussion I've seen recently is around renewably-made hydrogen due to removing the fugitive methane problem. E.g. Sweden's Boden plant stegra.com/the-boden-pl...

Three plants in one! Green hydrogen, green iron and green steel. We are creating sustainable change in heavy industry for generations to come.
