In a accident in a vehical once that tank or container is cracked open you would be amazed in how fast hydrogen disapates, literally in seconds.
Unlike gasoline, or LNG that stays around and ignites.
They have actually done tests on vehicles that might still be on your tube to see what happens in a accident between different fuels, if you , or some call hydrogen a fuel.
I also saw a video of a hydrogen welder of a commercial where they sell these hydrogen welders.
They say that welding with hydrogen does some strange thjngs.
You know the burning bush that Moses saw and the flame didn’t consume the bush ? That flame could have been hydrogen.
In a car accident gasoline gets splashed all over the place, no wonder they use it in naplam.
LNG tends to seek the lowest point like water.
So which one would you want if there was a car accident ?
I’d pick hydrogen.... Be gone in seconds.
Ya but only the surface is exposed to O2 in a liquid versus a gas that disperses and spreads out quickly.
My chemistry teacher made a very volatile explosion using simple flour. He showed that the flour wouldn’t ignite very well in a pile on the dish. However when he tossed it in the air it ignited very dramatically AND it behaved like a chain reaction that consumed all (or most) of the fuel in an instant. The more a fuel is despersed the more volatile it is. To a limit of course. The question is can it sustain a chain reaction.
