No, it isn’t. Gasoline is dangerous, but it’s a liquid. H2 is a gas, under extreme pressure, and with a very low spark energy. The spark (ignition) energy is very important safety wise. Nothing will light without an ignition source. In fact hydrogen is more dangerous wrt to gasoline than gasoline is wrt to flour (yes, flour can explode). That is: Flour:gasoline < gasoline:hydrogen Hydrogen is dangerous. And that’s fine. [1] http://www.explosionsolutions.co.uk/110411020.pdf http://www.explosionsolutions.co.uk/110411020.pdf
