| Abstract | The aviation sector needs to become climate neutral with net zero emissions by 2050 in order to meet the Fly the Green Deal targets. Hydrogen has been identified as a potential energy source that could help the sector meet these ambitious targets. This study evaluated a new hybrid-electric hydrogen aircraft concept against conventional Jet-A1 and power-to-liquid (PtL) aircraft concepts in terms of economic and environmental impacts. The assessment methods that we adopted were adapted specifically for this purpose. The life cycles of the aircraft were modeled using discrete event simulations, and the results show that the hydrogen concept has similar costs to the conventional PtL concept and double the life-cycle CO2-equivalent savings compared to the conventional Jet-A1 concept. As such, the method allows early comparison of different aircraft concepts. |
