Abstract:
This study aims to determine the optimal fuel choice from a well-to-wake energy
perspective by means of a comparative energy analysis of real-world fleet operations using
green liquid hydrogen and synthetic sustainable aviation fuel. A calibrated Boeing 737-800NG
model was developed using the SUAVE aircraft design tool, and a validated surrogate
propulsion model was developed within NPSS and integrated into SUAVE. Three hydrogen
aircraft, with various tank technology levels and an extended fuselage, were sized for the
baseline design mission, maintaining fixed passenger capacity and design range. The in-flight
energy performance of the hydrogen and sustainable aviation fuel aircraft were compared for
the 29 real-world missions, in which the hydrogen aircraft yielded worse in-flight performance
for all flights. However, when analysing the well-to-wake energy consumption and renewable
electricity requirements, substantial energy savings could be obtained for the hydrogen
aircraft, which may be desirable to reduce the significant strain placed on renewable
electricity resources. Furthermore, it was found that a tank gravimetric efficiency of 50% was
sufficient for superior performance of hydrogen aircraft against all SAF scenarios, further
highlighting the potential of green hydrogen to minimise the energy demand of short-haul
aviation over synthetic SAF in the context of decarbonisation.
