Gasoline has a lower explosive limit of 1.2 percent, so it’s more likely to “explode” with an ignition source than hydrogen. Hydrogen disperses far more rapidly than gasoline vapor where ventilation is adequate.

Hydrogen’s upper explosive limit is actually 75.0. But where are you going to find an atmospheric condition where you have 75 percent hydrogen?

What about the fact that we are comparing a gas with a liquid and the fact that a gas is dispersed with the oxygen and more likely to consume all of the fuel a lot more quickly.
