Long-term storage does not have a future.
Most localities will store no more than two weeks' production. If local banked energy looks likely to get used up, and incoming transmission line power cannot be secured, they order a shipment of synthetic fuel (ammonia) from a solar farm in the tropics, or from a wind farm somewhere else. (Until those come online and undercut NG, they will burn NG.)
Expect most places that do buy batteries to buy no more than 4 hours' worth. Other media will be cheaper, beyond that.
If they need to keep the old combined-cycle turbines ready to spin up anyway, they are likely to favor banking a couple of weeks' fuel for those. They might install fuel synthesizers, but probably most will sell excess to the grid, which will absorb any amount, at the right price.
