In the UK I agree, it is, but some major work is ongoing nevertheless...here in Scotland two separate groups are running a village on Hydrogen and another company in orkney has already a contract to work with the RAF developing a hydrogen fuel trainer. Trial flights happened last year. It's persuading the government to invest that's the problem, although as countries like Korea (S) continue to develop it, it will spread. I'd guess it's electric until 2028 or so then a slow balancing out with hydrogen and whatever else is discovered!
For electric to work now, there just isn't enough power in the system. A lot of time and money is going to have to happen simply to ensure that when every Mr and Mrs Smith in the UK get home from work and plug in to recharge, the power is actually available to do it, because right now, it isn't. Not even close.
