Abstract
Methods and apparatus to produce hydrogen gas turbine propulsion are disclosed. An example apparatus to produce propulsion in a gas turbine engine includes a fluid line to transport hydrogen from a hydrogen supply and an inert gas from an inert gas supply to a gas turbine combustor. The apparatus also includes at least one heat exchanger coupled to the fluid line to heat the inert gas and the hydrogen in the fluid line.
Claims20
A fuel system comprising:
- a gaseous hydrogen supply;
- a cryogenic hydrogen supply;
- a first heat exchanger to heat first hydrogen fuel from the gaseous hydrogen supply and not second hydrogen fuel from the cryogenic hydrogen supply;
- and
- a second heat exchanger to heat the first hydrogen fuel and the second hydrogen fuel.
2 more elements
A fuel system comprising:
- a fuel circuit;
- a first hydrogen supply coupled to the fuel circuit;
- a second hydrogen supply coupled to the fuel circuit;
- a first heat exchanger coupled to the fuel circuit downstream of the first hydrogen supply and not the second hydrogen supply, wherein the first heat exchanger heats a portion of the fuel circuit that carries inert gas to a temperature that is greater than a liquification temperature of the inert gas;
- and
- a second heat exchanger coupled to the fuel circuit downstream of the first hydrogen supply and the second hydrogen supply.
3 more elements
A method comprising:
- heating first hydrogen from a gaseous hydrogen supply via a first heat exchanger and a second heat exchanger;
- heating second hydrogen from a cryogenic hydrogen supply via the first heat exchanger and not the second heat exchanger;
- and
- injecting the first hydrogen and the second hydrogen into a combustor of an engine.
