Obviously if the electricity used to generate hydrogen was green it wouldn't be too bad, but I'd imagine if they had their own on-site generation they'd end up using power from the grid which isn't so green.
The advantage of hydrogen is due to its far superior energy density compared to lithium based batteries the ranges can be a lot further, making them actually usable

Aye your right currently. I think Hydrogen will become mainstream in other areas though, boilers in particular and once you've got them using Hydrogen then there's no reason why cars etc can't use the same supplies. I'm sure they're looking for ways to make it cleaner now anyway and isn't there one opening in Teesside soon, could be wrong there though. In fairness though the electric batteries are less than environmentally friendly aswell especially when disposing of them every 5 year since they're deteriorate massively.
The biggest advantage though is it works like petrol so if they did have to refuel it's as easy as popping to a pump and it's done whereas electric obviously they have to sit around for hours waiting for them to be charged which is less than ideal. Well and I don't believe there is deterioration problems either (could be wrong there though).
