This assumes that the Hydrogen is stored in a Hydride. Some may use bottled Hydrogen. There is also the potential problem that escaping Hydrogen could accumulate somewhere, mixed with air forming an explosive mixture. If it happens to accumulate in the passenger compartment (e.g. carried in by the aircon), the occupants may not notice until it is too late (Hydrogen is odorless). Sometimes smoking kills instantly.
