I don’t think battery storage for the grid will ever be feasible unless costs come WAY down. They seem to be focusing on things like compressed air and other more mechanical methods of converting electricity back into stored energy rather than storing as electricity directly. The mechanical methods tend to be cheaper and have much higher cycle lifetimes.[/quote]
Battery storage will be part of the solution, just like the turbine solution you mentioned. Then there’s the timed incentive for charging as well with the gradual increase in EV percentage of overall fleet.
