Maybe in the future we could use desalination/resalination for power storage. There is a lot of sea out there.

In desalination, you're taking a substance that is literally worthless and turning it into something valuable (though cheap).

It seems unlikely that once you've got the water, the best available use for it would be dumping it back into the sea. (Which would be the easiest way to resalinate it -- since you're already desalinating, we can safely assume you're next to the sea.)

How would that work? Is resalination exothermic?

To the contrary, dissolving sodium chloride in water is slightly endothermic.
