Abstract
A system and method for supplying hydrogen to a combustor of a gas turbine engine includes supplying liquid hydrogen from a liquid hydrogen supply source to a hydrogen supply line that is adapted to be coupled to the combustor of the gas turbine engine. The liquid hydrogen is converted to gaseous hydrogen at a first pressure and is to a pump, which increases the pressure of the gaseous hydrogen to a second pressure. A flowrate of the gaseous hydrogen discharged from the pump is controlled using a fuel metering valve. A portion of the gaseous hydrogen discharged from the pump is received and stored in a high-pressure gaseous hydrogen tank, and a pressure-regulating valve maintains the second pressure at a substantially constant pressure magnitude.
