That’s why you put a vacuum in there. It’s made of nothing, so it doesn’t react, and there’s plenty of it in the universe. Besides, it’s also lighter than anything else you could throw in there.
If there is ever a tiny hole you go from a small hydrogen leak (dangerous but repairable) to a collapse of the entire airship and instantly falling to the ground
because hydrogen is famously inert and helium is abundant?
Jet fuel isn’t exactly inert either and we now have another 90 years of advances in technology since the Hindenburg.
Hydrogen is a 100 times harder to contain than jet fuel.
Or environmentally friendly if leaked. And leaks will happen.
I am somewhat confident that we could get a reliable H air ship, to be fair.

No risk, no reward. You wanna fly the coolest airship or not.
Perfect. Now you only have to find a way to contain that vacuum that doesn’t involve thick, heavy walls and we’re good to go!
Fantastium fibers should do it.
You can also use unobtanium plates with adamantium rivets if you want to make it look cooler.
