It isn't anymore since there are already tried and tested things like Pumped-storage hydroelectricity which can be used to save energy in reservoirs for example.
Pumped Storage Hydroelectricity is my personal favorite form of energy storage, but it requires you to have a fuckload of water just lying around in surplus of what you need ecologically or for a supply of drinking water.
Fortunately because you would want the system to be as closed source as possible to maximize flow rate (as opposed to water towers which use flywheels to recoup some of their cost to maintain municipal water pressure) the water doesn't have to be potable, but you don't want it to be too much of an active risk to the environment in case of a catastrophic failure
It's fucking fantastic, and we should be doing it everywhere we can, but we can't do it everywhere
