You’d only get the same outcome from using a balloon made out of thermite. If it’s just hydrogen, a leak would flare (if ignited), but it wouldn’t explode until enough oxygen mixes in with the hydrogen (again, if ignited). And something like a nitrogen tank being used to displace the lost hydrogen would prevent that from happening. The main thing would be getting to the ground before buoyancy is lost, but that would also be the case for a breached helium zeppelin.
