Or hybrid.

Or 'fuel cell'.

Or Flintstones.

Joking aside, that probably isn't as clean actually, hydrogen fuel cell
power won't produce any carbon as a by-product. Humans of course expell
CO2.

Yes, but if the carbon you expell is part of the biosphere's natural
turnover, and comes from nuffin' more harmless than solar power (as was
the case with Fred and family, what with them being stone age and living
without agrochemicals and tractors and whatnot), this has no effect on
atmospheric CO2.

Grow food, eat food: it's all solar powered, and if you're doing your
agriculture the old-fashioned way by hand and without powered machinery
or synthetic agrichemicals and suchlike getting involved, you're not
modifying the atmosphere's carbon content to speak of (unless you're
doing something like clearing the Amazonian rainforest or whatnot).

Hydrogen fuel cells, on the other hand, do add to the atmospheric carbon
content in an indirect way.

Where does the hydrogren come from? It comes from a process that
liberates lots of carbon dioxide into the atmosphere. As does getting
that hydrogen to the vehicle. Not to mention the carbon produced in
making the fuel cell, maintaining the vehicle, and so on.
