Schäfer, A. W., Barrett, S. R., Doyme, K., Dray, L. M., Gnadt, A. R., Self, R., O’Sullivan, A., Synodinos, A. P., & Torija, A. J. (2019). Technological, economic and environmental prospects of all-electric aircraft. Nature Energy, 4(2), 160–166. https://doi.org/10.1038/s41560-018-0294-x.

In this research article, authors perform a comprehensive evaluation of the potential for all-electric aircraft to become a viable alternative to hydrocarbon fuel-powered commercial aviation. They consider factors such as the energy, economic, and environmental implications of such a transition. The authors argue that for all-electric aircraft to be viable, batteries need to have a higher specific energy and lower costs, as well as a reduction in the costs and CO2 intensity of electricity. I chose this article for my research because it provides a thorough analysis of the technical, economic, and environmental prospects of all-electric aircraft. The authors consider both the potential benefits and drawbacks of such a transition and provide a realistic assessment of the necessary conditions for all-electric aircraft to become a viable alternative to hydrocarbon-fueled aviation. One text citation from this source is: “All-electric aircraft could greatly reduce the environmental impact of aviation” (Schäfer et al. 2019, 164).

The article focuses on the challenges associated with the implementation of a more electric aircraft (MEA) concept. The MEA is seen as a way to make aircraft more energy efficient and reduce their carbon footprint. The authors focus on the design of a dc-dc converter that interfaces between 270 VDC and 28 VDC bus bars in aircraft applications. They argue that while the Dual Active Bridge topology is well-known and promising, the presence of current and voltage ripples can be detrimental to the life of the battery and filtering components. To reduce the voltage gain requirements and minimize ripple, the authors propose a two-stage bidirectional converter that combines a three-phase interleaved buck-boost converter with the Dual Active Bridge. I chose this article for my research because it provides a detailed and practical examination of one of the technical challenges associated with the implementation of the MEA concept. One text citation from this source is: “An efficient and reliable bidirectional dc–dc converter is an indispensable part of More electric aircraft that is energy efficient and playing a curial role in meeting environmental goals” (Tahir et al. 2022, 1139).

This is text that offers an objective view of the electric aircraft and the innovative technologies enabling aircraft electrification. The book provides insight into the paradigm shift across different aircraft segments from General Aviation to Large Aircraft through case studies. The authors, who are industry veterans, address design constraints, timelines, and performance enhancements of electric aircraft. They analyze how fuel burn savings may bring more value for money with the delivery of new electric technologies. The publication balances futuristic approaches with the operational realities of the business and provides a general view of the progress made so far and what to expect in the future. I chose this book for my research because of its comprehensive coverage of the topic and its focus on the fundamental concepts and technologies behind electric aviation. One text citation from this source is: “From an environmental perspective, a lot of progress has been made thanks to the more-electric aircraft in service, such as the Boeing 787.” (Thalin et al., 2018, 226)
