It usually makes more sense to pump water to a nearby reservoir uphill. That water can be released back through turbines when solar production is lower - pumped hydro are basically giant batteries. So not so much pumping it back upstream, but a similar idea, just without expensive desalination.

Not a saltwater coast, but the Ludington plant on Lake Michigan is a good example of this: https://en.wikipedia.org/wiki/Ludington_Pumped_Storage_Power_Plant
I think they’re more asking about getting usable water than energy storage
Why not both?
