H2 transporter ship on fire

Seems even the transport ships for H2 are catching fire.

1,250-cubic-metre LH2 cargo tank. ...would like to see a cutaway of the vessel design that gives us detail as to safety.

Don't think these will risk going in any waters with inter factional troubles going on, could be a whole new game for somalian pirates!

Here is a pic of a now obviously defunct NASA space shuttle main tank..

"154-feet long and more than 27-feet in diameter, the tank was the largest component of the Space Shuttle and the structural backbone of the entire Shuttle system"

This issue of boiling off H2, as it warms/expands, does that also apply to HFC cars if parked up and not in use?

In short, yes.
I remember watching a video of the BMW 7 series with a hydrogen combustion engine and even with a double-layered vacuum insulated H2 tank, it'll empty itself of all its H2 after a couple of weeks. It has a boil-off pressure release valve on the roof to vent the gas.

Which is why you're not allowed to park H2-powered vehicles indoors.

I'd completely forgotten about the venting required in cars, so sitting at an airport for a few weeks in summertime means you could come back to a low / empty hydrogen powered car in theory!? ..how does this affect airport parking, multi-storeys in general, ...hmm

Likely that hydrogen cars will have to be parked in designated compounds for airports & the like d'ya think? (cost absorbed by everyone)

There's no way you'd be able to use the Channel Tunnel in a Hydrogen car that's for sure.

There's a lot of liability & limitations don't y'think folks?
