I mean idk if it exists. Energy storage just means potential energy creation/efficient extraction. Could put a huge heavy fucking weight and lift it up a tower. Then letting it spin motors (maybe some gearing so weight moves slow while turbine spins fast as it falls. Problem with everything is just optimizing efficiency.
That's what I meant by pumped storage. This requires hilly terrain.
Yeah didnt read my bad. Another system could be compressing air/some other gas. During the day and using the compressed gas to turn a turbine.
In theory that sounds like a pretty good option, but in the 30 seconds or so it took to type this reply obviously I couldn't research it lol
