Green steel is the perfect dispatchable load. The steps up until sponge iron require very little capex, with the input costs being driven by energy price it is a far better match for renewables.
Same goes for high temperature electrolysis.
The resulting iron stores 2-8kWh/kg with nothing more than a box as infrastructure (and maybe some oil or nitrogen to stop rust).
Both are so ideal as dispatchable loads that iron js seriously being considered as a fuel/energy carrier instead of hydrogen.
Then run the arc furnaces which are higher capex and labour cost but a fifth of the energy at a constant rate.
The idea of buildkng nuclear to run green steel is utterly deranged.
