Have you actually read the article pin brain?

and I quote (to save you the bother) :-


"
38. Electric vehicle manufacturing produces approximately 23% more
emissions than that of a gas-powered car.
(Green Car Congress)

The US air pollution statistics have revealed that the bigger the
vehicle thats being manufactured, the larger the battery. Or, in other
words, the greater the emissions.

Fortunately, due to battery recycling, the decarbonizing of electrical
grids, and an increase in battery energy density, emissions from battery
manufacturing could be reduced by a whopping 49%.

Whats more, both BMW and Tesla encourage their battery-recycling programs.

They state that even though battery production emissions may be high
during production, in the long run, emissions from electric vehicles as
a whole are lower than gas-powered cars.

And I'd expect them to improve as production is scaled up and methods evolve.


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?

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

I thought it was down to how practical it was to make hydrogen in quantity
at local 'fuel station'
It;s quite a bit of intrastruction for a garage to have enough capacity to my hydrogen on the spot.
And then storing it safely.

Cost (and ruinously inefficient compared to just charging a battery).

Doesnt mean to say that it wont have a place, but economics will
determine that itll be used only where battery charging isnt a practical
option.

I guess that's not also factoring the cost of the damage / pollution
done mining the lithium (and as long as it lasts) versus a good supply
of fully renewable seawater?

Doesn’t mean to say that it won’t have a place, but economics will
determine that it’ll be used only where battery charging isn’t a practical
option.

So no other factors ever come into these decisions?

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.

And Austrian car workers building Jaguar iPace's

But what is its life expectancy against that and the generation of the
electricity over that period?

This must be a day that ends in "y".

Part of the problem, is the analysis is a moving target,
and some of the assumptions are years out of date.

https://www.carbonbrief.org/factchec...climate-change

https://www.teslarati.com/tesla-ev-b...study-results/

"The 2017 study claimed that the production of EV batteries emits
around 150 and 200 kg of CO2 per kWh. However, a new study,
summarized in a recent press release from IVL, showed the amount
of CO2 emissions from battery production has been reduced to
between 61 and 106 kg of CO2 equivalent per kWh."

Another variable, is the type of batteries used. The Model 3
produced for the Chinese market uses lithium iron phosphate
(fairy lamp) batteries, while the North America version
uses lithium cobalt (laptop) batteries. And maybe this suits
the domestic battery production industry.
