March 19, 2026, © Leeham News: In our series on the state of alternative propulsion projects, we have analysed electric hybrid projects and found that these do not make for an operationally acceptable airliner. They are more expensive in production, thus in purchase, and their operational costs are not lower than the aircraft they shall replace.
Projects analyze hybrids after realizing that battery-electric airliners are too limited in range. But soon, the problem areas of hybrids become clear. The studies then swing to hydrogen propulsion systems.
