Nissan has already started rolling out Vehicle-to-Grid (V2G) or Vehicle-to-X (V2X) chargers for its offering of vehicles since 2022, so it's already happening.
Chris Nelder, who runs the Energy Transition Show podcast and who is a member of the Rocky Mountain Institute, published a paper even as far back as 2016 arguing how the potential for the US consumer rolling stock of BEVs (Battery Electric Vehicles; grid + batteries only) and PHEVs (Plug-in Hybrid Electric Vehicles; grid + batteries + gas) offering Demand Response services to utilities is enormous.
I'm not sure about the V2G compatibility of BEMUs feeding energy back to the grid to serve Demand Response is where the industry is going currently, instead favoring the implementation of overhead line islands as compared to extensive grid rollouts, but that reality is 100% feasible. The island approach I believe is also what Siemens is aiming for with the overhead-fed trucking solution I shared earlier.
Still exciting nonetheless!!!
