Reply to comment by Angry_Washing_Bear in Cryo-compressed hydrogen, the best solution for storage and refueling stations? by Hypx

Years ago, and I thought this was hilarious. I watched a segment on hydrogen fuel for cars.. I'm talking 12 years + ago.

but they claimed it was 100% safe and unlike gasoline, a fire would just vent out of the hydrogen tank.. They demonstrated this on a open vehicle frame.. They talked about how it's safe since hydrogen fires burn straight up. So in their demonstration... the tank was UNDER THE DRIVER'S SEAT burning straight up.

Epic! o.o

Not sure if any of that was just a marketing claims, investment demo, etc but i found it funny.

Bigger issue is when you have no vent and heat just builds up around the entire tank.

E.g. parking house fire, a fire on a packed ferry and similar.

Definitely, just found it comical how even that was 'safe'

Even with a vent, its a serious issue.. where will the hydrogen go. But yes, without a vent you're gonna get a large over pressure event
