Who's afraid of the Big Green Hydrogen?

Speaking as somebody who makes a living out of assessing equipment for use in explosive atmospheres, I have to say that the thought of the use of the most easily ignitable of gases becoming commonplace fills me with joy, and hopefully dollars.

I think it is no more dangerous (maybe less so) than propane tanks currently in cars/taxis/buses etc.

It's different, not more or less dangerous. Hydrogen leaks much more easily because it has such small molecules, but it also disperses much quicker, and doesn't hang around on the floor like propane as it's lighter than air.
The energy and speed of a hydrogen explosion is much faster and more violent than propane, and the pressures developed are higher. You'd be surprised how freaking loud a hydrogen explosion is with just a liter of enclosed gas. It's not a squeaky pop like you get at school, more like a gun going off.
It's much easier to ignite hydrogen with an electrical spark - it has the lowest spark ignition energy of any gas or vapour.
And that concludes the combustion science lecture for today.

Phibes, Phibes, Phibes… Everyone knows that water is made up of 2 parts hydrogen, and one part oxygen. We also know that oxygen is EXTREMELY combustible… Now, as water is obviously not combustible, and in fact is so non combustible that we pour it on fires to put them out, then it is painfully obvious that hydrogen can not be combustible and in fact, has to likely be the most non flammable material in all existence.
It’s simple science.

Hydrogen
Nazi misinformation.
Funnily enough, the majority of the fire wasn't hydrogen burning, but oil and superstructure. A hydrogen fire is almost invisible and doesn't produce smoke.

OK, smart guy, if hydrogen is so safe how come they make atomic bombs out of it?
I was only joking

It’s the atoms, not the hydrogen…
And atomic bombs aren’t anywhere near as bad as nuclear bombs.

Maybe the Hindenburg was actually a failed Nazi nucular attack on the US of A.
Hey, it could happen! Canada was close by.
