I have the impression that the problem of hydrogen leakage from vehicles is vastly exaggerated. A study on two commercial hydrogen cars found leakage rates of 2-6 mL/min (Table 4 in [1]). At this rate, it would take over 15 years for the tank content of a Toyota Mirai (5 kg of H2) to leak out.

- mikeyouse 4y agoThe Hydrogen isn't leaking from vehicles since they take so many precautions to ensure they don't, including those tight tolerances and special materials. You just need to replicate that at every step of the supply chain which becomes onerous and expensive.
