Item type:Publication, Access status: with files , Life cycle sustainability assessment of potential battery systems for electric aircraft(Elsevier, 2021-03); ; ; ; The Flightpath 2050 strategy sets ambitious goals for aviation to reduce its environmental impacts. Therefore, new propulsion concepts that avoid in-flight emissions are being developed. Particular attention is given to (hybrid) electric propulsion systems based on batteries, fuel cells, and synthetic fuels that replace the conventional jet engines. This paper assesses the environmental, economic, and social impacts of eight potential battery systems for short-range aircraft from a life cycle perspective and conducts a pre-selection of suitable technologies. The results indicate that lithium-sulfur batteries are advantageous compared to lithium-ion batteries in terms of environmental as well as social and economic impacts.Publicationtype: Journal ArticleScopus© Citations 17 57 146 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Life cycle engineering of future aircraft systems : the case of eVTOL vehicles(Elsevier, 2020); ; ; ; This paper introduces the first steps towards a general modelling framework for the integrated life cycle engineering (LCE) of future air transportation systems. The focus of analysis lies on the potential environmental implications of batteries powering electric vertical takeoff and landing aircrafts (eVTOLs), which have emerged as an option for urban air mobility to alleviate automobile traffic in cities. The impact of main influencing factors on the sustainability of eVTOLs is discussed, presenting the main modelling requirements for an LCE framework to accompany the transition towards a more sustainable air mobility.Publicationtype: Journal ArticleScopus© Citations 18 81 655
