> You want to start with demand response, then continue with overgeneration, then continue with pumped hydro. Pumped hydro is in the class of solutions I had in mind. An example would be a refrigerated warehouse using off-peak power to freeze large blocks of ice to be used later as heat sinks. > Even if you wanted lots of stationary batteries, there might be better candidates For some applications (an orbital LINAC/railgun, for example) you would want large banks of capacitors rather than batteries.
