can hydrogen be made less combustible?
I have no wish to drive a 4 wheeled hindenberg.🤣
Whilst acknowledging the laughy face,
..it's actually a fairly common question, often asked seriously.
It's relatively no less safe than carrying around a tankful of highly flammable petroleum. Petrol tanks do not spontaneously combust, and almost always withstand even serious crashes (except in the movies/tv where they always explode, because slack jawed yokels like explosions!). You can bet the car safety quango will be all over hydrogen cell cars to make sure they are at least as safe.
Indeed an engineering professor I knew said that the early days of steam power took scores of lives, because heating up a container to high pressure is incredibly dangerous.... but we used that tech to power the industrial revolutions in factories, trains and steamships. With experience we found ways to make it safe.
- Anyone seen reference to gas-bag cars during the war? (They converted Jones's Van in Dad's Army to gas). Their weakness was leaks rather than explosions.
- The Hindenberg did not spontaneously combust (or any other loony theories). The Mythbusters did an entire episode investigating it, and turns out the unsafe part was not the hydrogen...
