As with anything, there’s got to be an economical advantage, and somehow there has to be an incentive for you to participate in this system. Surely no electric car owner would let the utility company charge/discharge ones battery at will given battery degradation per such cycle. With large scale hydro pump-up, you loose about 15% energy per cycle. Thus, for car batteries to be viable, they have to match that loss rate, and hopefully also be able to squeeze out a small profit for the car owner. If not, I just don’t see this happening.
