Researchers at the FAMU-FSU College of Engineering have designed a liquid hydrogen storage and delivery system to facilitate zero-emission aviation. The system integrates fuel storage, cooling, and delivery control, allowing hydrogen to serve as a clean fuel and coolant for critical power systems on electric-powered aircraft. The study, published in Applied Energy, focuses on a design tailored for a 100-passenger hybrid-electric aircraft utilizing hydrogen fuel cells and turbine-driven superconducting generators. By optimizing cryogenic tanks and subsystems, the team achieved a gravimetric index of 0.62, enhancing fuel mass utilization. The system efficiently manages thermal requirements by utilizing liquid hydrogen for both cooling and fuel purposes, eliminating the need for mechanical pumps. Tank pressure adjustments control hydrogen flow to meet power demands during different flight phases. Future plans involve experimental validation of the system at FSU's Center for Advanced Power Systems under NASA's Integrated Zero Emission Aviation program in collaboration with partner universities, aiming to advance clean aviation technologies.
