The energy from the EV batteries is available to the electric grid to serve peak needs, with the vehicles recharging during non-peak hours. Using EVs as decentralized electric storage resources, or batteries on wheels, minimizes the need for capital investments in the grid to support ever-increasing demand, while lowering operating costs.

Well, then, youre back to coal burning power plants, and a dirty little secret the H2 hypers dont like to discuss: The electrical storage efficiency of water electrolysis, compression for storage, and PEM fuel cell combined is only 23%. The combined electrical storage efficiency of charger and batteries is 85%.
