Vehicle-To-Grid V2g Tested In Pilot Programs, Faces Challenges To Scale Vehicle to Grid (“V2Gˮ) is the use of electric vehiclesʼ bi-directional charging capabilities to provide services to the grid. There are currently 40m EVs on the road globally (including PHEVs and BEVs), totalling over 1,300 GWh of energy storage (relative to approximately 340 GWh of stationary energy storage through end of 2024. As both markets continue to grow, V2G technology continues to evolve to allow EV owners to monetize their vehicles by connecting them to the grid. As with VPPs, V2G is deployed by having thousands of distributed storage batteries charging or discharging simultaneously. V2G has been deployed extensively in pilot programs, it has yet to be adopted widely at scale. There are many technical and economic challenges to deployment:

V2G requires charging and discharging, while some vehicles do not physically allow for bi-directional power flow

There is no standard across vehicle manufacturers, or communication profiles, so most V2G programs must be run by a specific manufacturer

The technology requires a high number of vehicles participating to result in significant economies of scale
