Great comments, thanks guys.
Hydrogen fuel is very interesting, and I'd like to know which companies you've been looking as Hasiba or anyone else (if you don't mind divulging!)
one issue with hydrogen is the pressure and sometimes cooling required for storage.
One of the huge advantages of hydrogen over batteries is energy density (pressure and cooling allowing). For any aircraft, large people carriers to small drones, hydrogen is surely the way to go, as its provides so much more energy per weight than Li batteries. There are companies developing hydrogen PEM cells for drones which allow almost double the payload capacity and 3 x the flight time compared to LiPo batteries.
