Take a look at the graphs at the back. It shows a 99.99% reliable grid made up of an optimal mix of solar & wind, 3x over-provisioned along with 3 hours of storage and a continental grid.
We don't need 3x over-provisioning because the paper doesn't include hydro or existing nuclear. And 3 hours of storage is a lot of batteries, but it's a lot cheaper than building new nuclear.
It only requires over-provisioning of 20%. https://mitpress.mit.edu/books/electrify
Here's an anti-renewable paper that quite ironically makes the point quite well that battery storage is quite viable: https://www.nature.com/articles/s41467-021-26355-z
