1. A system, comprising:
a cryotank configured to store a liquefied fuel therein;
a pump fluidly coupled with the cryotank and configured to provide a first stream of the liquefied fuel from the cryotank while compressing the first stream of the liquefied fuel to an increased pressure;
a heat exchanger coupled with the pump and configured to provide cooling duty to the first stream of the liquefied fuel from the pump;
an expansion valve configured to expand the first stream of the liquefied fuel from the heat exchanger into a multiphase stream comprising a liquid phase and a gas phase, the multiphase stream having a temperature lower than an initial temperature of the first stream from the cryotank; and
a liquid-vapor splitter fluidly coupled to the expansion valve and configured to separate the liquid phase and the gas phase in the multiphase stream, wherein the liquid phase is configured to be returned into the cryotank,
wherein the liquid-vapor splitter is configured to provide the gas phase to the heat exchanger for providing additional cooling duty to the first stream of the liquefied fuel from the pump.
