I had to check the numbers because it grabbed my attention.

No issue with your quoted figure of 30,000 TWh (annual) global electricity consumption.

But we only need to do 7TWh of battery supply in year 1 (or say only 1-2 of that makes it to grid storage).

30,000/365 is 82 TWh daily. So that’s the number to crack, surely? Because a significant percentage of storage will be to make up for wind and solar, which generally approximately follows some sort of diurnal cycle?

If we will be closing in on a couple TWh annual storage capacity in 6 years (leaving aside any real synchronised attempt to get vehicles to be part of large scale distributed grids) then only a few years on from 2030 we’re going to be able to store a significant percentage of our daily energy demands
