Researchers at the FAMU-FSU College of Engineering have developed a pioneering liquid hydrogen storage and delivery system aimed at revolutionizing sustainable aviation. The system is designed to address various engineering challenges, allowing hydrogen to function not only as a clean fuel but also as a cooling medium for critical power systems in electric aircraft. Published in Applied Energy, the study introduces a scalable system tailored for 100-passenger hybrid-electric planes. By integrating hydrogen fuel cells with turbine-driven superconducting generators, the design showcases efficient storage, safe transfer, and strategic cooling capabilities throughout all flight phases. The research team optimized key design parameters, achieving a notable gravimetric index of 0.62, indicating a significant portion of usable hydrogen fuel in the system. By adopting a dual-function approach, the system leverages thermal integration to cool high-efficiency cryogenic components and absorb heat from various aircraft systems. The innovative pump-free delivery system utilizes tank pressure regulation, with advanced feedback loops adjusting hydrogen flow rates based on power demand profiles. Simulations demonstrate the system's capacity to meet peak power demands during critical flight phases. The project, part of NASA's Zero Emission Aviation program, involves collaboration with top academic institutions in the U.S. and is progressing towards experimental validation. With a focus on system-level optimization and real-world implementation, the research team aims to advance the commercial viability of hydrogen-powered aviation, highlighting a significant milestone in clean aviation technology.
