At a somewhat small and unassuming airport in Maribor, Slovenia, German hydrogen propulsion startup H2FLY has quietly been building up to a major milestone in zero-emission aviation over the summer. And all the hard work has come to fruitio
World’s first crewed liquid hydrogen plane takes off::undefined
Do you know how brittle metals become at very low temperature ? Did you notice I did not talk about hydrogen explosiveness ?
But sure, let’s now talk about explosiveness. Do you know the mixture ratio range is completely different (much greater) for air + H2 explosive mixture as compared to other mixtures ? You are very far from an expert on the topic aren’t you ?
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.
Well you know what else is explosive? Jet fuel!

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