Re:Green steel without green hydrogen – can it work?

This is entirely going to depend on how governments treat 'blue hydrogen' (ie. hydrogen produced from natural gas where the carbon is injected back underground).
If blue hydrogen is treated as carbon-free by treaties and taxation schemes, then it will be a cheaper energy source than electricity, so it will be used to power steel, concrete, glass, and all the other heat and energy heavy industries.
If however blue hydrogen is put in the bin of dirty fossil power, then steelmaking via hydrogen will prove to be more expensive than direct electrolysis.
