Interesting.... I did read the link!

And the origin of the fuel? I expect it is currently derived from fossil fuel? Maybe zero exhaust emissions but not exactly helping the planet, is it?
Only when there is a large surplus of green electricity will hydrogen production become sensible (if even then).

Aberdeen is surrounded by alternative power sources, all of which will no doubt be contributing. The North Sea and inner Moray Firth are full of wind turbines [to the extent that 'The Trump' complained they were spoiling the views from 'his' golf course], the hills are alive with turbines too so.....

But the leccy is not used to produce green hydrogen, is it? So absolutely no contribution towards reducing fossil fuel usage. The electric is a far higher grade of energy than hydrogen - even if the hydrogen is/were used in a fuel cell/battery system (like the “Riversimple“ hydrogen powered cars).
This technology will only be efficient when there is a surplus of non-polluting energy. Full sop!

If you say so, although I sense you're Hell bent on being confrontational - so in the words of Duncan Bannatyne of 'Dragons' Den' fame...."Ah'm oot".

It’s not ‘confrontational’. It is simply fact.
Do they not? I guess you have to use too many to make it viable?
@slim_boy_fat the point @not done it yet is making, albeit in his usual blunt fashion, is that although hydrogen has the potential to be very green, at the moment the production of it largely depends on fossil fuel. It's either created directly from fossil fuels, or it's created rather inefficiently using electricity, which by and large is still produced from fossil fuels.
If we had an unlimited supply of zero emission electricity, hydrogen would make a lot of sense, but as it stands, producing it using electrolysis is only 70-80% efficient, so before you even get it in to a vehicle, you've lost 20-30% of the electricity needed to make it. A battery vehicle on the other hand will maintain over 95% efficiency getting fuel to the vehicle.

Maybe we will run out of electrons. Are they a finite resource?!

I've been reading about co2 being combined with hydrogen & a common catalyst to produce a liquid hydrocarbon fuel . Still in its infancy it's hoped to use it as a diluter for aviation fuel (4% polluter production ) and later as it gets cheaper as vehicle fuels .
Anyone else seen the article or able to expand onnit?

Had an Aunt , a lay preacher no less , take it into her head that the big old apple tree in the gounds of the village hall next to her new bungalow was a nuisance. She went to the nearest ironmongers and purchased three pounds of 1 & 1/2 " long copper nails. hammered then in a foot up from the ground head to head all round the trunk , 20 yr later it was still there dropping inedible apples and leaves in her back yard .

Given that lithium is in such short supply isn't it more sensible to encourage the car industry to make 10 PHEVs (or however many can be made) instead of 1 EV?
10 PHEVs will likely collectively easily do 200-300 emission free miles daily (given average commutes)...a single EV isn't going to drive 200-300 miles every day of its life.

There is lots of lithium out there, more and more folk are coming up with new ideas for retrieving it at a reasonable cost both financially and environmentally.
Smaller EVs which are more efficient would be the answer for commuting rather than PHEVs but then you have the vast majority of the public who perceive they "need" a vehicle that can do 300+ miles before recharging.

I love it.
Amazing how old stuff became new again.
I'm flummoxed at the inventor claiming anything innovative about that, either.
