STANDARDS & COMMITTEES Hydrogen fueling at airports * Categorization of hydrogen fueling speeds (flow rates in kilograms per minute), based on airline turnaround time, which gives a first definition of coupling size categories. * Fueling process parameter definitions for gaseous hydrogen and liquid hydrogen fueling of aircraft at airports and mobile and stationary station use cases. * High-level hydrogen properties, including safety definitions. Next steps SAE AE-5CH Hydrogen Airport Task Group has determined that the next step in standardization is to develop a liquid hydrogen fast fueling process and couplings to support the development of liquid hydrogenfueled aviation in the upcoming standard SAE AIR8999, starting with small and regional aircraft. The SAE AE-5CH Hydrogen Airport Task Group is led by Jesse Schneider, with Zuhair Mir of GKN Aerospace serving as vice chair and Jason Damazo, Ph.D., of Boeing as secretary.
