The growth in the aviation sector has highlighted the need to decrease carbon emissions, a significant factor in climate change. Hydrogen is a potential alternative fuel due to its high energy density, and its combustion mostly results in water. The use of hydrogen fuel cells further eliminates nitrogen oxides emissions, making hydrogen a zero-emission energy source. However, due to its low volumetric energy density, it is desirable to store hydrogen in liquid form at about 20 K. The low temperature of liquid hydrogen presents challenges in its storage and transfer, but the cooling power it provides enables the use of superconducting components in the power system, reducing power loss, increasing power density, and increasing overall efficiency. As a collaborative effort in developing integrated zero emission aviation (IZEA, a NASA ULI), we present the design concept for a liquid hydrogen storage system for short-range aircraft with a gravimetric index greater than 0.6. Our design leverages the cryogenic cooling power of liquid hydrogen to support the temperature of various power system components, such as the high-temperature superconducting (HTS) generator, HTS motor, DC power distribution cable network, and power electronic converters. By controlling the pressure in the storage tank, we demonstrate that it is feasible to deliver the desired mass flow rate of hydrogen while effectively cooling the power system components using practical heat exchangers. This work represents a significant advancement towards developing the complete IZEA thermal management system.
