And the water is liquid.

  Sure, but if you’re burning H2 in pure O2 you aren’t producing nitrogen oxides, and if you’re burning H2 in air, you end up with a whole lot of N2, CO2, and Ar left over, residual H2 or O2 (because your combustion is not exactly stoichiometric), and a relatively small fraction of nasty nitrogen oxides as side products. (And yes, you can and should condense out the water so you can recover the higher heating value instead of the lower heating value, and H2 will have the nice property that the condensate won’t be especially acidic, unlike boiler condensate from hydrocarbons, which is annoyingly acidic.)

    Ah ok. Well the fact remains you have an exhaust with elevated nox. So the 3 options are to stop the nox being created to start with (no nitrogen), convert the nox into something else (nitrous oxide?) or release/store/use the nox for something. I'm not a chemist so I don't know what's possible / economic, thus the question.
