Yeah, electricity pricing for consumers is mismatched in terms of how energy demands work. Solar has the opposite problem where it may be unable to supply energy when you need it which is a much bigger problem - instead of losing money your energy grid goes down. Of we turn on peaker power plants because while batteries can weather short outages I don’t believe anyone has demonstrated running a grid off stored energy for any reasonable amount of time.
And again, I’m going to call it an unsubstantiated claim that hybrid nuclear plants that can scale energy output as needed are uneconomical. I know they’re slightly more expensive but I’m not aware of any data suggesting that it is actually intrinsically uneconomical. Same goes for any claims that solar or wind is cheaper than nuclear - all the data I’ve found had solar as way more expensive and wind as slightly more expensive vs nuclear.
And I wouldn’t hold my breath on storage. I think we’re less likely to get a crazy new battery technology that solves all the things we need from it in a cheaper and safer way than nuclear research. There’s lots of crazy battery ideas but those ideas have been around for a long time and we have no indication that can scale. China is building a molten salt reactor right now. And additionally we don’t need government R&D dollars flowing into battery research as much as we need it flowing into figuring out how to make nuclear even safer and more economical. Normal market economics are already a big enough prize to cause private R&D dollars to go after that (batteries are everywhere and the essentially the same battery tech that’s in your smartphone is what’s in an EV which makes the market opportunity massive and obvious - that’s not as obviously clear for private investors for nuclear energy because it need regulatory approval to build a plant which means we don’t know how big that market would actually be). It’s not nuclear vs solar. It’s nuclear vs fossil fuels and renewables vs fossil fuels and so far fossil fuels has kicked renewables’ butt and had it butt kicked by nuclear. If this were a fight, where should the actual smart money be in terms of achieving net zero?
