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.
In the event of a spill or accidental release, CNG poses no threat to land or water, as it is nontoxic. CNG also disperses rapidly, minimizing ignition risk when compared to gasoline. Natural gas is lighter than air and will not pool as a liquid or vapor. Nevertheless, indoor leaks can form a flammable mixture in the vicinity of an ignition source. CNG is primarily methane, which is a greenhouse gas that could contribute to global climate change if leaked.
