I wonder if hydrogen fuels poses any unique risks as compared to petrol.
It's highly explosive.

One of the reasons that make hydrogen difficult to work with in this sense is that hydrogen (H₂) molecules are so small that they can permeate most materials, such as steel. Then it can get somewhat easily to wherever there is a spark, and chaos ensues. Annoyingly you don't even need 100% Hydrogen for that to happen, as it can ignite with a concentration of just 4%.
After we stopped using Hydrogen mostly as a consequence of Hindenburg's accident, it's taken years to perfect hydrogen fuel cells to a safety standard that can be used in cars. As far as I know, its use has been limited to rockets/space propulsion otherwise (where you can just throw millions at the problem to make it safer).

Okay, I knew from texts books that H2 is small but I never thought of the real-life consequences of it being so small. Then theoretically, Helium should also be "leaky", right?

schrieb am 19. Juni 2025, 07:17 zuletzt editiert vonYep, helium is even worse for leaking! It's actually the smallest noble gas and can escape through tiny pores that even hydrogen can't fit through. Thats why helium balloons deflate faster than air balloons - the atoms literally seep through the balloon material.

Maybe in a century we can. But only maybe.
