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_hydroelectricity https://en.wikipedia.org/wiki/Pumped-storage_hydroelectricit...), which is interesting but also very sensitive to the geography.
