Hydrogen isn't explosive, it's flammable. Just like jet fuel.

Detonation
"A very wide variety of fuels may occur as gases (e.g. hydrogen), droplet fogs, or dust suspensions. In addition to dioxygen, oxidants can include halogen compounds, ozone, hydrogen peroxide, and oxides of nitrogen. Gaseous detonations are often associated with a mixture of fuel and oxidant in a composition somewhat below conventional flammability ratios."

For Hydrogen, if I recall correctly, the explosive range is from 4% to 75% hydrogen in air. I may dig a little bit more to find sources.

How many more false experts want to comment on this ? And feel free to downvote, you only underline your ignorance and arrogance.

Yes, when you combine a flammable substance and an oxidant, you can get an explosive. But hydrogen is flammable. It isn't an explosive. Explosives have their own oxidants.
