1. A method of operating a fuel management unit for a fuel system, the method comprising:
receiving data indicative of a state of an exhaust assembly using a sensor of the fuel system, the state of the exhaust assembly comprising a temperature of a working gas flow within the exhaust assembly;
determining an amount of a hydrogen fuel in a liquid phase to provide to a hydrogen delivery assembly in response to receiving data indicative of the state of the exhaust assembly;
directing one or more components to provide the determined amount of the hydrogen fuel in the liquid phase to the hydrogen delivery assembly;
converting, with the hydrogen deliver assembly, the determined amount of hydrogen fuel in the liquid phase to hydrogen fuel in a gaseous phase;
determining an amount of hydrogen fuel converted to the gaseous phase; and
comparing the amount of hydrogen fuel converted to the gaseous phase to a desired amount of hydrogen fuel in the gaseous phase.
