You simply can't though. Furthermore you're evading the numbers.

Efficiency (power plug to wheels )

Hydrogen car with ICE ~ 6%
Hydrogen car with fuel cell ~ 12%

Electric car ~ 70-80%

It's a no-brainer really !

Graham, you're the one with no brain. Where are the costs? If I buy
a battery powered car for $65,000 - and I have to replace a $50,000
battery every 2 years or 800 charge cycles - whichever comes first -
I'm not ahead even if it only costs $0.08 per kWh to recharge it.

I just did some sums.

Okay.

15kWh will be enough electricity for most ppls' daily run. I can readily support
those numbers.

I'd like to see that. 15kWh by the way is less than 1/2 gallon -
less than 2 liters - of petrol. What are people riding on their daily
run? Electric wheelchairs?

A full size (by European standards at least) car. The 'gasoline equivalent mpg' at a constant 70 mph for example is ~ 100 mpg.

50 miles is adequate daily commuting distance for most ppl and a hybrid EV of the same ilk carrying a small 30 bhp diesel generator will have
essentially unrestricted range. The diesel gennie also has the advantage of being able to provide additional heating energy from its coolant circuit
in spring / fall / winter and cooling (either mechanically or electrically driven in summer).

Yes, EV's are that good.
