Wikipedia says "Titanium is one of the few elements that burns in pure
nitrogen gas". Maybe for a liquid air hybrid you could make use of the
nitrogen as well? Otherwise, I can't see how it would be superior to
lithium hydride or aluminum hydride.
Might also be interesting with N2O, if the Ti would burn with the N2 and
leave the O to react with the H2. If (dim) memory serves, Ti is just
about as willing to react with nitrogen as with oxygen -- the ash from
titanium burning in air is about 80% TiN -- so maybe that would work.
The TiN would be useless as an exhaust gas, since it solidifies at very
high temperatures, but the energy released might make it worth the
trouble.
