A hydrogen fueled power system of a vehicle includes a liquid hydrogen fuel source having a volume of liquid hydrogen fuel and a thermal engine configured to expand the liquid hydrogen fuel into gaseous form via interaction between a heated first portion of the hydrogen fuel and a second portion of the hydrogen fuel. A heat exchanger is positioned between the liquid hydrogen source and the thermal engine, and is configured to heat the first portion of the hydrogen fuel via thermal energy exchange with a relatively warm fluid. A turbine is located fluidly downstream of the heat exchanger and upstream of the thermal engine, and is driven by the heated first portion. A power generator is located fluidly downstream of the thermal engine. The power generator utilizes exhaust from the thermal engine to generate electrical or mechanical power. A compressor is operably connected to and driven by the turbine.
