OOI does that include the CO2 produced when the electricity used to
re-charge the batteries is generated ?

Finding 'gross impact' seems to be tricky. Very rarely see non-fuel
particulates discussed too.

As an aside to that, what happened to hydrogen / fuel-cell cars?

They were never viable and the hydrogen came from coal/natural gas.

Now we have all this spare electricity (to charge EV's g)
why couldn't we use it to electrolyse seawater instead?

Because that's even less viable.
