The aviation industry is under increasing pressure towards de-carbonization and electrificationof commercial aircraft. However, their range limitations are heavily dependent ontheir expected battery energy storage capacity, and the direct operating costs of this propulsiontechnology are still not well understood. This paper provides a forecast of mission and directoperating costs of two fully electric commuter airplanes resembling the EL19 and the EviationAlice, as well as a hybrid-electric aircraft resembling the Do328HE, operating in Sweden inthe 2030 to 2070 time frame. NASA’s forecast for battery specific energy is used as inputfor aircraft models, allowing for the estimation of the maximum expected range under threescenarios: pessimistic, nominal, and optimistic, along with its respective direct operating costs.Results suggest that fully electric technology could become feasible for short domestic routesin Sweden in 2040, with the hybrid-electric model being able to cover longer routes earlier.Direct operating cost models project lower expenses for electric and hybrid-electric conceptscompared to smaller conventional aircraft, although they still remain more costly to operatethan the larger regional aircraft they plan on replacing. This research stresses the need forrealistic technological forecasting and financial awareness in developing sustainable aircraftconcepts, particularly regarding the commercial viability of electrified flight in Scandinavia.
