Assignee: GENERAL ELECTRIC COMPANY
Field: Engines, pumps, turbines (Mechanical engineering)
Classification: CPC F | IPC F

Claim 10:
11. A gas turbine engine comprising:
a turbomachine comprising a combustion section and an exhaust assembly arranged in serial flow order, the turbomachine further comprising a sensor;
a fuel system comprising a hydrogen delivery assembly positioned in thermal communication with the exhaust assembly and in fluid communication with the combustion section; and
a controller comprising a non-transitory memory and one or more processors, the non-transitory memory storing instructions that, when executed by the one or more processors, cause the gas turbine engine to perform operations, the operations comprising:
receiving data indicative of a state of the exhaust assembly using the sensor of the turbomachine;
determining an amount of a hydrogen fuel in a liquid phase to provide to the hydrogen delivery assembly in response to receiving data indicative of the state of the exhaust assembly; and
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.
