EVs are a brilliant idea ... until (as others here have said) you look at the vehicle charging infrastructure; I'd buy an plugin EV if I could be sure of decent range and loads of FAST charging stations. My observations when out and about is how scarce they are and when you see one that works there's usually a queue of cars waiting to get a connection. I currently drive a 'mild hybrid' - 3 litre diesel engine with a big battery under the floor for the leccy motors so don't plugin. They talk about fast home charging but most of the UK housing stock has limited electrical capacity - if you're lucky it'll be 100amps but more usually 80amps so good luck with getting a fast charger with that sort of 'crippled' supply even if you're lucky enough to have a driveway to park the motor; ditto the street lamp idea ... limited electrical capacity.
So what about the hydrogen route ... makes sense for HGVs until you look at our old friend the infrastucture issue. There's an article in The Engineer magazine discussing the issue in the USA and the ENORMOUS cost of building it.

So, SYM says, burn the diesel and to hell with polar bears.
