EUROCEA-034 / SAE AIR 8466 Guidelines for Airport Hydrogen Fueling Stations

EUROCAE ER-034, developed in collaboration with SAE's AIR8466, provides the first step in defining performance targets and safety limits to enable hydrogen as an accessible fuel for various commercial aircrafts. Considering the wide range of aircraft with hydrogen storage sizes, SAE AIR8466 and EUROCAE ER-034 also define fueling categories for hydrogen eVTOLs, Regional, Narrow body and Widebody (including Lighter than Air).

This document includes:

• Range of estimated hydrogen storage onboard based per aircraft type and use case.
• Categorization of hydrogen fueling speeds (flow rates in kg/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.
