Climate and energy impact analysis of electric, hybrid-electric and hydrogen aircraft in prospective scenarios for air transport

Résumé

To meet climate impact reduction objectives, the aviation sector must both accelerate the improvement of the fleet efficiency and the deployment of low-carbon energy carriers. This implies to develop new concepts of aircraft with a reduced climate impact than previous ones and possibly more energy efficient. One research direction is the investigation of electric, hybrid-electric and hydrogen aircraft concepts to possibly reduce emissions. Indeed, these concepts imply the direct usage of electricity or hydrogen from electrolysis which may be potential low-carbon energy carriers. Evaluating the climate impact benefits and energy implications of the deployment of such aircraft architecture is intricate. This paper presents an analysis of different deployment and technological assumptions for these concepts. The analysis which consists in assessing the climate impact benefits of these new aircraft architecture in terms of CO2 effects will be performed. The assessment of absolute energy consumption will also be achieved. This will enable the performance comparison between architectures and to consider their contribution to the decarbonization of the whole air transport.
