Re: Liquid hydrogen
"its a highly efficent transport mechanism."
Yes, *on paper*. You seem to forget that it *has* to be at least -170C and >100bars or so *just to stay liquid*.
And when it doesn't: *BOOM* says your container. Hydrogen *is really bad stuff to transport*. Really.
Liquid hydrogen is a genuine pipe dream for hydrogen fanatics, it's not feasible in any large scale transportable application .
