H2 is a truly hell to handle. It ex-filtrates through most other
metals, makes Steel, (and other metals), brittle* as is does so, when
stored under pressure. It requires constant refrigeration in liquid form
with the same problems. It's a medium for transport of energy not a
source. NASA engineers who've worked with the stuff, will candidly
tell you that Kerosene/O2 rockets are much simpler to engineer with
fewer problems. I don't see how H2 as an Automobile fuel will ever be
wide spread without major advances in materials science.
