>Charging cars is a great application even though cars are expensive to build... Its also logistically hard to actually get the energy back into the grid from cars. Driving around with it is fine but if you cant put the energy back into the grid at peak time you still have to over produce more energy in total than just to cover the peak. It uses the energy which is good but it does not reduce the difference between peak demand an low demand. If that is reduced it has an overall larger impact than just to using the excess energy. Pumping water back up into a reservoir is the most common and probably oldest way to store excess grid capacity like an actual grid batter (one that gives energy back to the grid). Ofc its not feasible in many places due to the lack of hydro power plant but there are other ways to actually store energy and deliver it back to the grid unlike the Buttcoin battery nonsense.
