Vehicle to grid is only 80% efficient and prematurely wears the battery.
Given that utility scale solar is much cheaper than residential solar, I wouldn’t be surprised if utility scale energy storage is also cheaper than vehicle storage.
Lithium ion is optimized to be light, which is not an requirement for grid storage, which could make use of molten salt, pumped hydro, compressed air, or hydrogen electrolysis.
