Just thought I'd share my experience, that may be of interest in this debate.
My penultimate job before retiring was at a fuel cell company.
An attractive view that was held at the time was that Hydrogen would be extracted from water using solar powered hydrolysis.
The Hydrogen would power vehicles, generators etc. The by-product is water and so the cycle begins again.
Just reinforcing Reckers' point, we converted a 3500 kg delivery van from 115 kW diesel power to battery electric. We data-logged it and ran it on food delivery cycles in London. It had regenerative braking and fantastic acceleration. Amazingly, the average power requirement on this duty cycle was only 5 kW! So using an on-board 5kW fuel cell as a generator should suffice.
At the time, the technology would not lend itself to higher duty cycles, like sustained motorway driving and, as far as I know, that challenge remains.
