Storing hydrogen isn't hard because its explosive, it's less volatile than gasoline.
Storing hydrogen is hard because it's low density until it approaches absolute zero and is smaller than and embrittles the best materials we have to store it.
If batteries are a worry for replacement, imagine leaking embrittled pressure tanks that have to be checked every year and replaced sooner than every 5.
- BenjiWiebe 3y agoHow do you figure it's less volatile than gasoline?! Hydrogen has a far lower boiling point (=volatility). Or did you mean how explosive it is? Hydrogen has a far wider range of explosive concentration than gasoline. Autoignition point is lower for gasoline than hydrogen if you meant that, but the wide range of explosive concentrations for hydrogen seems like it would pretty much negate that safety benefit.

- BenjiWiebe 3y agoThat's my point. The GP (IIUIC) was saying that hydrogen was safer than gasoline and I was disagreeing.
