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 past, formulators had to choose between flammable propellants like hydrocarbons and dimethyl ether, which have low global warming potentials (GWPs) but are VOCs, or a nonflammable propellant, like HFC-134a, which is not a VOC but has a higher GWP, said Terrence Hahn, vice president and general manager of Honeywell Fluorine Products.
