This is fundamentally a pricing problem that hourly-matched carbon-free energy accounting tries to solve. https://www.eurelectric.org/in-detail/247-2/
Natrium has an interesting design for a 345MW reactor that has thermal storage that can boost output to 500MW for 5.5 hours. This lets it increase output during peak prices.
I mean, sounds kinda cool. But that 2023 idea is very clearly not going to happen in the current US political environment.
We’re in an era of brutal capitalism, and nothing else matters but price. Not even emissions sadly. Green compacts like this have no chance, and neither do nukes. Unless they pay the right bribes for some subsidies.
