The four-horse race to decarbonise steel

I am curious if these processes need continuous power or if they would work okay if most of their power was delivered during the daytime.

I suspect that you don't need that with aqueous electrolysis. I think the advantage is the electrolytic cells are cheap.

Problem with solar is intermittent power means intermittent use of capital equipment. How much an issue that is depends on the ratios of electricity cost, capital cost and depreciation.

If you only run in daytime you have the same capital costs for half the output - a lot harder to make viable. Might be OK if the energy cost dominates anything else?
