Alan, Atiq of course anything can happen in the future but as it stands, and for the foreseeable future, EVs will be the car of choice between the two. There are problems with both choices with regard to their green credentials but nothing is perfect. Hydrogen will have a part to play in the green revolution but probably as a means of storing energy. So as it stands governments and manufacturers world wide are pouring £billions into battery tech and infrastructure, most of which would be useless for hydrogen cars, so unless all of this is to be thrown away in favour of hydrogen EVs have won, if won is the correct word.
Have just been reading your post about the new VW car coming in 2 years time with a 700km battery pack…staring to think I may be wrong about the need for Hydrogen except for trucks maybe that need to do very long distances…700km is 434 miles which I think would suit the majority of people.
