Will electric vehicle batteries satisfy grid storage demand by 2030?
Renewable energy and electric vehicles will be required for the energy transition, but the global electric vehicle battery capacity available for grid storage is not constrained. Here the authors find that electric vehicle batteries alone could satisfy short-term grid storage demand by as early as 2030.
Can EV batteries be used as energy storage devices?
Batteries in EVs can serve as distributed energy storage devices via vehicle-to-grid (V2G) technology, which stores electricity and pushes it back to the power grid at peak times. Given the flexible charging and discharging profiles of EVs and the cost reduction, V2G has been considered for short-term power grid energy storage 193.
