I've thought about this before but the issues is that the energy is dinged 3 times by inefficiency losses. First when you capture it from the sun(or whatever), then when you pump it and convert it to potential, then when you let it out and use it to generate.
They actually already do this to some extent, I think the "St. Lawrence Pump Station" is one facility.
- snowwindwaves 14y agothey already do this a lot more than to some extent, it is quite common. Batteries have an internal impedance as well which means losses putting energy in and taking it out. 15% loss on a battery is a reasonable estimate
