You wish that costs for renewables were not still plummeting, and for storage were not falling more than twice as fast as for renewables, and that costs for building and operating nukes were not, instead, rising. But they are, they are, and they are.
Pretending that "breakthroughs" will be needed to field storage must be your last hope, but building out storage is just construction. You will continue to be disappointed.
You insist storage costs are cheaper, but the reality is that we can't know the cost until storage plants are actually built. You're comparing the actual costs of nuclear, with the promised costs of storage. We have actual costs for hydro and battery storage, but they are too high. We only have promised costs of electrolysis, ammonia, or what have you because none of the approaches have actually been built.
Come back to me when electrolysis storage systems are actually built, and we can examine the actual costs of storage the same way we examine the costs of nuclear: by looking at the bill after the plant has been built. If you really are so confident in their efficacy, then this should be no problem.
