| Because you can't run steel mills and other big energy consumers with solar or wind.

Ah, the Argument from Bad Engineering. If you stop and think real hard I'm sure you could imagine many ways to do this. And they'd be cheaper than trying to run steel mills off nuclear reactors.

Ok, then: What's you're preferred form of industrial-scale energy storage?

For this application? Pumped hydro, high temperature thermal in firebrick (a technology used by the steel industry in the 1920s), and hydrogen.

Also, adapt iron/steel production to use direct electrolytic methods, although that's going to require more R&D. The potential for dispatchability of demand is enormous.
