The question isn't whether you'll need storage at all. It's whether it's cheaper to build enough storage for windless nights, or baseload nuclear and enough storage for remaining demand discrepancies.

I think the latter is more feasible without too much wind, since solar predictably goes to zero when demand is lowest. I don't think it's at all clear that a grid with high amounts of wind instead of nuclear would be cheaper.

Yeah, hard to tell given the dramatic drop in storage costs.

Today, I agree that if we could make the switch overnight that solar + storage would probably be a lot more expensive than nuclear + storage.

However, who knows in 10 years. I could see liquid metal batteries becoming extremely economical.
