Abstract

The final financial decisions on starting the commercialization of the next single-aisle aircraft programs for entry-into-service in the 2030s are due in less than 5 years. These programs will shape the future climate impact over the following 20–30 years of this aircraft segment and will determine if the sector can achieve its 2050 net-zero target. And so far, there are only limited holistic research perspectives available evaluating the best decarbonization options for such a crucial next product. This study provides a first-of-its-kind holistic evaluation approach for the business case of single-aisle hydrogen-(H 2 )-powered aircraft to enable true-zero CO 2 flying. It combines the optimization of green liquid hydrogen (LH 2 ) supply and aircraft designs as well as the investigation of operational strategies with such aircraft in one specific air traffic network. It is found that LH 2 could cost around 2 to 3 USD/kg at main European airports in a 2050 scenario. Even though the aircraft with H 2 direct combustion would be less efficient, average total operating costs would be 3% lower than flying with synthetic kerosene in the given network in 2050. As an operational strategy to save fuel costs, tankering might play an essential role in reducing operating costs for H 2 -powered aircraft in the early adoption phase with high differences in LH 2 supply costs. Finally, it is derived that usage of LH 2 as a fuel would lead to lower installation requirements of renewable energy generation capacity compared to the synthetic kerosene option. Since green electricity will be a constrained resource in the next decades, this is another important aspect for choosing future decarbonization options in air travel. All in all, the study proves the importance of the derived methodology leading to a broader techno-economic assessment for two decarbonization options in aviation. Such novel approaches might be further developed and applied to other related research topics in this field. • Optimized LH 2 supply costs for 104 airports incl. Comparison of best supply pathways. • Four optimized H 2 -powered single-aisle aircraft designs and operational strategies. • Comparison of total direct operating costs for kerosene, synthetic kerosene, and LH 2 in a given air traffic network.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
