SYSTEM FOR PRODUCING DILUENT FOR A GAS TURBINE ENGINE

A gas turbine engine (100) including a catalytic reactor (240) and a combustor (150). The catalytic reactor (240) configured (i) to receive hydrogen fuel, (ii) to receive air containing oxygen, (iii) to catalytically react at least a portion of the oxygen in the air with at least a portion of the hydrogen in the hydrogen fuel to produce water, and (iv) to output diluent comprising the catalytically produced water. The combustor (150) includes (a) a combustion chamber (152) and (b) at least one nozzle (162, 166) that is fluidly coupled to the catalytic reactor (240) to receive the diluent output by the catalytic reactor and configured to inject diluent into the combustion chamber (152).
