We need natural batteries like solar power lifting water from a lake into a reservoir so that when we need that energy and the sun isn't making it, released water does
A cubic meter of water above your roof has the storing capacity of a AAA cell. That's why you need huge, massive damms to store any significant amount of power. But unfortunately it's not flexible enough (you need mountains nearby) or dense enough.
What about storing energy as potential energy using some high density objects. This may work.. Right?? gravitricity Check out their work.
It's slithly better the more dense the material, but that's basically the same thing. You could say that depending on the location, using water is much more practical.
A much more interesting one I saw was the molten salt ones, where basically you store the energy as heat in a sealed place, and then when you need it, you use that heat to run turbines.
Yes, suspended weights, also spinning flywheels, hot salt, hot sand
There's options besides pumped hydro, hydrogen and batteries
Interesting concept, thanks for sharing
I don’t think it’s feasible.
