HYDROGEN INFRASTRUCTURE AND OPERATIONS Airports, Airlines and Airspace
The method to generate and deliver hydrogen to the airport will depend on the airport’s size, location, geography and the scale of hydrogen demand. It is anticipated that most airports will initially be supplied with liquid hydrogen generated and liquefied off-site, transported by tanker to the airport.
However, as demand increases, particularly for large airports, supplying hydrogen by road or rail may become infeasible, requiring an alternative approach. While it would be possible to generate hydrogen at an airport, the high energy requirement will likely result in on-site electrolysis being unattractive.
Therefore, hydrogen supply through a gaseous pipeline with onsite liquefaction at the airport may become the preferred solution. Whether liquefied off-site or at the airport, aviation’s unique requirements for liquid hydrogen would likely make it one of the largest users of hydrogen liquefaction.
