Yeah, some solutions I've read include filling in old pit mines (many of which were dug out of salt veins because it's easy to get through), brine based storage solutions as a heat battery or ultra-cooling facilities for data centers.

Each solution has it's own problems of course, like salt leeching into ground water tables and a lack of scale to handle the possible output of brine.

Atmospheric condensation is a bit of a troublesome issue in it's own way though right, because you're altering the climate distribution of moisture. Not that we aren't altering everything all the time, but imagine if a country were to divert the flow of water from a river that historically ended in another country.

Only then imagine you're doing it with the rivers in the sky instead. Obviously it would be quite a while before capture technologies scaled up to that point, but it's not out of the realm of possibility.

A few days ago I read a headline about salt based batteries being more efficient than lithium batteries. Maybe there’s a way to create batteries while also generating both power and clean water at the same time: https://energycapitalpower.com/researchers-develop-sea-salt-battery-4-times-the-capacity-of-lithium/

Yeah I think they brinier the better for those too.
