From the TiH MSDS: Contact with water releases hydrogen gas.
So it's probably a no-go for amateur rocketry.

Wait a minute...a hybrid with the Isp of candy propellant where the
oxidizer is liquid Nitrogen? No LOX cleaning. No monopropellant. The
fuel isn't anything exotic and can be shipped as a 4.1 flammable solid.
There actually may be a place for this in amateur rocketry.

FWIW on a quick series of runs with Propep 3, optimum Isp is just under
160 seconds for a TiH2:N2 ratio of 75:25.
Optimum mixture of sorbitol and potassium nitrate is about 155 seconds.
It doesn't appear that the game is worth the candle, unless there are
other whiz-bang kinetic properties that will only show up with testing.
