1. An assembly for a turbine engine, comprising:
an annular combustor comprising an annular combustion chamber;
a fuel injector nozzle configured to inject a fuel-steam mixture into the annular combustion chamber for combustion; and
a fuel system including a non-hydrocarbon fuel source, a steam source and a manifold, the steam source including a water reservoir fluidly coupled to an evaporator, the manifold configured to mix a non-hydrocarbon fuel received from the non-hydrocarbon fuel source with steam received from the steam source to provide the fuel-steam mixture, and the fuel system configured to deliver the fuel-steam mixture to the fuel injector nozzle,
wherein the non-hydrocarbon fuel comprises hydrogen gas.
