Abstract
Methods and apparatus to produce hydrogen gas turbine propulsion are disclosed. An example method includes activating at least one heat exchanger operatively coupled to a fuel line, injecting hydrogen into the fuel line to distribute heat from the at least one heat exchanger in the fuel line, and in response to a temperature of the fuel line being greater than a liquification temperature of an inert gas: injecting the inert gas into the fuel line, terminating injecting the hydrogen into the fuel line, and capturing the inert gas in the fuel line.
Claims20
A method comprising:
- activating at least one heat exchanger operatively coupled to a fuel line;
- injecting hydrogen into the fuel line to distribute heat from the at least one heat exchanger in the fuel line;
- in response to a temperature of the fuel line being greater than a liquification temperature of an inert gas:
- injecting the inert gas into the fuel line;
- terminating injecting the hydrogen into the fuel line;
- and
- capturing the inert gas in the fuel line.
A method to shut down an engine, the method comprising:
- causing fuel to distribute heat in a fuel line;
- in response to a temperature of the fuel line being greater than a liquification temperature of an inert gas:
- injecting the inert gas into the fuel line;
- terminating injecting the fuel into the fuel line;
- and
- capturing the inert gas in the fuel line.
A method comprising:
- heating a fuel line in preparation for an engine shut down;
- injecting hydrogen into the fuel line;
- injecting inert gas into the fuel line to move the hydrogen out of the fuel line;
- and
- capturing the inert gas in the fuel line after the hydrogen is moved out of the fuel line.
