Batteries are a bit too expensive to make sense as stationary storage outside of some specialty cases right now. But EVs have been economical for a while. So while we wait for battery prices to drop, two way EV charging absolutely make sense as a transition technology. Most of those EV batteries are sitting unused for large chunks of the day, and the entire capacity of the battery is often only needed by the driver a few times per year. Adding two way charging is not a prohibitive cost, and that installation can be reused if/when an onsite battery is added in the future. The rest of the program can be managed with software.
