Could you elaborate on what storage you have in mind? The only effective way we have to store large amounts of electricity right now is [pumped-storage hydroelectricity](https://en.wikipedia.org/wiki/Pumped-storage_hydroelectricit...), which is interesting but also very sensitive to the geography.
I'm by no means an expert, but as far as I know a combination of batteries for fluctuations in the dozens-of-hours range and Power-to-{Methane,Hydrogen,Ammonia} for seasonal variations is what experts think feasible.
