New study about the intial development phase of LH2 supply for aviation

What makes an airport suitable to be a “first mover” in H2-powered aviation?

In this paper, now published in Energy Conversion and Management: X, we evaluate the initial development phase of LH2 supply for H2-powered aviation (around 2035). Using linear optimisation models for the techno-economic analysis, this study evaluates the best-suited hydrogen supply routes (including LH2 capsule supply) and the role of additional gaseous hydrogen demand at the airport.

Here are some of the main findings:

Airport location:
Airports located in regions with favourable conditions for renewable energy sources and sufficient land availability benefit from lower LH2 supply costs. Proximity to potential GH2 cavern storage further enhances cost-efficiency.

Space for infrastructure:
Airports that offer plenty of space – typically smaller or regional airports – are better positioned to accommodate LH2 production, storage, and refueling infrastructure.

Proximity to H2 demand hubs: Cooperation is key
Airports near other industries or airports with LH2 demand can benefit from shared infrastructure, further lowering LH2 supply costs.

Experience with H2 in ground operations:
While GH2 demands at or near the airport could lead to slightly lower LH2 supply costs, experience with H2 at the airport can also be an advantage for the ground operation of H2-powered aircraft.

Infrastructure utilization and seasonality:
High utilization of H2-powered aircraft and consistent flight schedules are key. Seasonal flight patterns, however, may lead to higher H2 supply costs due to lower infrastructure utilization.
