If 272 million light duty vehicles in the US were all 100 kWh BEVs, they would store enough energy to run the entire US electricity grid for two and one-half days, holding 27,248 GWh. We will be halfway there by 2040.pic.twitter.com/jNzExxaC5E
Re grid backup - the grid will need up to ~30 days storage for full backup of renewables, so V2G is only a small part of solution. I think H2 will do the heavy lifting.

Hydrogen is definitely good for longer term storage, but BEVs feeding back into the grid is a no brainer once battery longevity improves (like how Tesla’s latest patents portend). I’d be interested in reading about the 30 day requirement if you have an article or paper to link.

This blog post and paper by
@KenCaldeira from 2018 is a good overview and links to other work as well. I agree V2G is a no brainer but seems like we'll still need additional bulk storage.https://kencaldeira.wordpress.com/2018/03/01/geophysical-constraints-on-the-reliability-of-solar-and-wind-power-in-the-united-states/ … - Još 8 drugih odgovora

Not to mention that EV owners may have the possibly in reasonable expectation that they can use them?
