Hydrogen Infrastructure and Operations

The on-airport distribution of liquid hydrogen to the aircraft is initially likely to be through mobile bowsers. However, as demand increases, a liquid hydrogen hydrant system may be required.

Due to the properties of liquid hydrogen, the hydrant installation would be more complex than that
used currently for kerosene, requiring cryogenic pipelines and storage. While most technology required for supplying hydrogen to airports and aircraft already exists, developing the infrastructure at the scale required for airports will be challenging.

Refuelling aircraft using liquid hydrogen presents unique challenges in maintaining turnaround speed and safety. As liquid hydrogen has a lower density than kerosene, larger diameter fuel hoses will be required, and the additional safety constraints of hydrogen may require an expanded fuel safety zone.

However, automation or remote control of ground support equipment and new safety procedures could help maintain competitive turnaround times.

Realising liquid hydrogen powered aircraft has the potential to revolutionise the future of global air travel keeping families, businesses
and nations connected while addressing the sector’s carbon emissions.
