NASA’s award of a $253M contract to GE Aviation and MagniX to develop electric aircraft propulsion (EAP) technology over the next five years reflects the growth of EAP innovation, as well as economic and environmental pressures, according to GlobalData, a leading data and analytics company.
Francesca Gregory, associate analyst at GlobalData, commented: “Electric aircraft have the potential to disrupt the aerospace industry by challenging the dominance of hydrocarbon propulsion. Since the start of the pandemic, fallen passenger numbers and growth in public environmental concern have promoted the use case for electric aircraft. For example, Airbus is developing its own solution in the form of its electric quadcopter.”
Batteries have been viewed as a limiting factor to EAP in the past. *Research has established the requirement for a battery with an 800 Wh kg-1 energy density for an all-electric flight of 600 nautical miles (NM), with recent innovations enabling significant progress towards this aim.
Indeed, GlobalData’s recent report, "Electric Aircraft in Aerospace and Defense – Thematic Research," establishes a healthy target market for EAP, revealing that 50% of all departures pre-pandemic were for flights under 600NM. Ongoing improvements in battery energy density will enable EAP to demonstrate its potential to play a major role in commercial flight.
The COVID-19 pandemic continues to disrupt commercial aviation’s operations as travel regulations stifle the recovery of passenger numbers. The outbreak has questioned the industry’s long-term profitability and spurred a trend towards lower passenger capacity aircraft.
The GlobalData report, "Key Trends in Business Travel (2021)," confirms a 77% decline in business travelers between 2019 and 2020, and only predicts a slow recovery of passenger numbers beyond 2024. This trend has dire consequences, as business travelers constitute 75% of commercial aviation’s revenue. Similar patterns in international tourist numbers suggests radical adaptation is required.
Gregory continued: “The scrapping of Boeing 747 production in 2022 reflects a wider trend towards smaller carriers and lower passenger numbers. This development provides an opportunity for EAP systems, which are suited to lighter aircraft and allow aircraft manufacturers to clinch a ‘green restart’ from what has been a disastrous period for the industry.”
The growing phenomenon of "flight guilt" among an increasingly environmentally conscious public requires commercial aviation to meaningfully tackle its negative environmental impact which is becoming more pronounced with aircraft engines now responsible for up to 2% of the world’s carbon output.
Gregory adds: “Despite mounting environmental concerns, commercial aviation has been slow to change. Structural transformation is needed if passenger numbers are to recover to pre-pandemic levels. Electric aircraft may provide a commercial advantage going forward as emissions standards and carbon taxes will increase the cost of operating a hydrocarbon fleet. The emerging EAP industry could therefore offer an excellent opportunity for commercial aviation to make the changes needed.”
