This boils down to "There are lots of EV batteries, we can use them as storage!". It seems to ignore practical issues:
People drive during the day, and charge at night. So you could use EVs as a buffer during the night, but they still need to be charged. So EVs are still going to be a net energy consumer during the night, when you need the storage the most (no solar production).
I think the best course of action is to load shift charging of EVs and use it as "storage" in that way. Its an easy load to shed when needed, and an easy load to ramp up when renewables are plenty.

- dahfizz 4y ago> most cars aren't used every day Huge citation needed. > most cars are parked during the day Yes, parked somewhere where there is no V2G infrastructure. By the time we pay millions of V2G charging stalls, we would be better off just buying actual grid scale storage.

- dahfizz 4y agoFrom your source: > this suggests an average of just under 18 trips per car every week. So cars on average are used multiple times a day. OP's claim that most cars aren't used is ludicrous.
- gwbas1c 4y ago> So EVs are still going to be a net energy consumer during the night, when you need the storage the most (no solar production) Solar isn't the only green energy source, there's also wind, hydro, nuclear... Historically, electricity consumption is low at night. With the conventional grid, nighttime charging is a net boom because it brings load when the grid has excess capacity.
