In a recent study, researchers from the European Environmental Bureau (EEB), the Stockholm School of Economics (SSE), and the Potsdam Institute for Climate Impact Research (PIK) questioned the planned development of new nuclear capacities in the energy strategies of the United States and certain European countries.
Here’s an example of what can be done with 5 hours of storage. 5 hours is a 25% participation rate of V2G where the participants offer a third of their battery capacity.

If going with the (false) assumption that nuclear can hit 100% grid penetration, it would take decades to offset the carbon released by causing a single year of delay.
The lowest carbon “let’s pretend storage is impossible and go with 100% nuclear” would still start with exclusively funding VRE.
