First off, they’re loading those hydrogen tanks into the area the Dash 8 uses for cargo and it looks like a couple rows of seats to boot. They’re gonna lose even more seats because people aren’t going to be ok with a “no luggage” rule on their flight. Second, the normal range of a Dash 8 is two to nearly three times that. I know the three things airlines are always willing to give up on are cargo volume, passenger count, and range. Also, one conspicuous detail I didn’t see in the article is anyone asking the FAA if they’re ok with this idea and I just can’t help but think they might have a little tiny problem loading up six tanks into the back of a passenger plane, the failure of any of which will literally blow the aircraft in half.

Because when it comes to its use as a fuel that is hydrogen’s only positive. The negatives include the collapse of global air travel back into the domain of the wealthy alone. Global air travel’s piece of the global warming pie is only about 3% which is not insignificant but it’s also not what’s killing our planet. You know what does have tremendous benefits, minimal if no downsides and even some upsides for consumers, and will have dramatically bigger GHG savings? Electrification of railways and vehicles, improving public transit, and transitioning to nuclear power.

Yeah, a 1,200 liter, 10,000 psi tank catastropic failure, I’m absolutely sure you’re right and that flying tin can will tank that like a boss. I'm sure there's absolutely no test footage of much, much smaller tanks turning the back end of cars into so much confetti.
