- usrusr 5y agoCryogenic, or some hybrid. If insulation involves some actual gap I'd imagine that reliable methods to detect any cookoff failures would be simple and having access to a near sonic airsteam should give plenty of emergency venting opportunity. You'd still have a serious problem, but more of the ETOPS kind than of the fireball kind.
- ncmncm 5y agoNot under pressure. Liquified, at atmospheric pressure, and vented to make ignition of leaks impossible. There is a minimum partial pressure of hydrogen that must be exceeded before it can ignite. Keep leaked hydrogen below that, and it is harmless.
