As has been explained to you numerous times, reservoirs are normally constructed, not found, and no lake or river is needed. So, you really do just need a hill with unused top. (Penstocks and turbines are also constructed.)
There will be no need for "one day's" worth of batteries, but in any case battery production is ramping up fast, and that will continue as long as demand increases.
Numerous storage technologies will be used. It is not clear yet which will be cheapest. Hydrogen might not be among them.
- Manuel_D 4y agoYou need a lake to fill the artificial reservoir. Pumping water over long distances is prohibitively expensive. You also need a lower reservoir, otherwise how do you refill the upper reservoir once it's been drained? Its more than just a hill. Numerous storage technologies are proposed. And you're just assuming that one of the proposed solutions will work.

- moloch-hai 4y agoYou now insist that no hilltop pumped-hydro storage without a river exists? It is an odd choice of falsehood to insist upon, when it may so easily be looked up.
