Can you pls elaborate why nox is produced? I thought too that burning hydro means just water

  Burning would produce just water only when done in pure oxygen. Normally burning is done in air, which has more nitrogen than oxygen. At the high temperature of the flame, a small part of the nitrogen also burns, producing nitrogen oxides, besides the hydrogen oxide, a.k.a. water.

  In air: hot nitrogen (~80% of air) + oxygen present -> some nitrogen will react even though it's not the fuel input. Not much different from burning other stuffs in air, really (gasoline / diesel included). Of course the burn conditions have a big effect. And cleanup after the burn (catalysts) is possible. But imho the more sensible thing would be to input the H2 into a fuel cell.
