Gasoline is also an extremely flammable fuel, and one that does not escape like hydrogen.. The hydrogen fuel cell tanks in the Toyota Mirai are pressurized up to 10,000 psi, and hydrogen is 16 times lighter than air.
If a little air leaks into a volume of methane (natural gas) there is little hazard, since mixtures over 13.3% are not inflammable. The same is true of gasoline. If a little air leaks into a volume of hydrogen, the hazard is great, for then the gas will explode, not just burn.
