Following up on my posted above, this excellent YouTube video provide some useful additional information:-
Jeff Dahn mentions V2G, looking at the range of chemistry options Ni94 might be the referred option as it appears to have no cobalt.
The Austin cathode plant should eventually ramp to a capacity of 60 GW, IMO all of these cathodes will probably be used for vehicles.
Jeff also mentions progress on Sodium-Ion, it is likely Sodium-Ion / LFP will be used for storage, not Single Crystal High Nickel, if if Nickel winds out on a cost per cycle metric. Those nickel cells are simply too valuable for V2G.
Jeff also mentions Sodium in short range EVs 250-300 km. That is probably the cheapest entry level Gen3 car, if it happens, IMO Tesla is planning for this, and intending to allow it, but may not need to do it.
Some additional thoughts.
1) The V2G vehicle might have to interface to a Powerwall, it may even be a DC charge of a Powerwall if that is viable (and faster), The advantage here is after charging up the Powerwall the vehicle is free to go and doesn't need to hang around to power the house. Cheapskates trying to avoid the purchase of a Powerwall may be out of luck.,
2) V2G may allow Cybertrucks to provide an emergency "reasonably fast" charge to NACS cars. So if Tesla uses some Cybertrucks for mobile service, each mobile service Cybertruck is a mobile emergency charger.
3) Overall I see V2G as being for privately owned cars, starting out with higher end cars with big battery packs, After Cybertruck, Roadster Model S/X might be next in line. Model S/X may need a new battery pack, or perhaps there are ways of arranging single crystal 18650s.
Finally.
