There’s barely enough lítium available to switch every existing car in the world to EVs. Nevermind the amount needed to supply overnight power to a grid. We’re going to need a different kind of battery, but those are still being researched.
Hydro batteries are a solution, but not one that fits everywhere. You don’t get nearly all the amount of energy back that you put into it. Then there are other considerations like availability of water (salt water corrodes, and current desalination processes are expensive and require a lot of power, which is part of the problem it would be trying to solve).

We can use lithium, but we can’t afford i because there is just not enough batteries are getting made to build enough storage to stabilise grid. Hell, there is a not enough batteries for cars. Over the time it will be resolved, problem is that it will take too long. Hydro is not an option, there is just not enough places in AU to build required capacity.
