This "Large" Electric Airliner Could Take Flight by 2033

The future of electric aviation is being shaped with boldness and innovation. A Dutch startup, Elysian, has just unveiled its ambitious project: the E9X, a fully electric airplane capable of carrying up to 90 passengers. Boasting an impressive range, this airplane could revolutionize air transport in the coming years with a potential first flight in 2033.


The E9X concept relies on advanced battery technology, with a theoretical density of 360 Watt-hours per kilogram. This density significantly surpasses that of Tesla batteries, which are estimated between 272 and 296 Wh/kg. Thanks to these high-performance batteries, the E9X could reach a range of around 500 miles (800 kilometers) on a single charge. The company even envisages extending this range to up to 620 miles (1,000 kilometers) through future improvements.

This project is the result of a collaboration between Elysian and researchers from the Delft University of Technology. Two articles published on January 4th in the American Institute of Aeronautics and Astronautics (AIAA) journal have laid the groundwork for this innovation. The first article challenges existing assumptions about battery technology for electric airplanes, suggesting that advancements could allow for larger airplanes to house denser batteries.

The second article details the approximate dimensions of the E9X, including integrated batteries in the wings and foldable wingtips. The airplane would have an energy consumption of 167 Wh per passenger-kilometer, representing a significantly lower environmental impact compared to traditional or alternative fuels, such as electrically sustainable aviation fuels (eSAF) or hydrogen-based options.


If the E9X becomes a reality, it will not be the first electric passenger aircraft. The Eviation Alice, designed to carry up to nine passengers and two crew members, has already completed a prototype flight in September 2022, aiming for full production by 2027. Alice has a range of about approximately 290 miles (460 kilometers).

The development of the E9X is a giant leap towards a greener future for aviation. However, challenges remain, particularly in terms of battery energy density and adapting ground infrastructures. The evolution of these technologies and regulations will be crucial for the realization of this project.
