Grid Storage is very expensive and right now only has a few hours of capacity. We would need weeks to really replace nuclear.

Saying that grid storage "only has a few hours of capacity" is like saying that a nuclear power reactor "only has 1GW of power." You solve both issues by deploying more. And if you want a longer lithium ion battery installation without the additional power capacity, you can save a bit on inverters.

Grid storage is cheap enough that Texas, a purely profit-driven grid is now overtaking California in the amount of battery storage deployed. 58GWh of new grid storage was added in 2025 alone, and the growth is still exponentialhttps://seia.org/news/united-states-installs-58-gwh-of-new-e...

Incredibly disingenuous for nuclear power proponents to state that grid storage is expensive. Your entire argument centers around the most expensive power generation available and one of the slowest to build.
