Electric flying is one of the most promising innovations in the aviation industry. By 2024, significant advances have been made that bring the future of sustainable flying closer. Here are some of the key developments:
Breakthroughs in battery technology
One of the biggest challenges for electric flying has always been the energy density of batteries. In 2024, researchers at TU Delft and start-up Elysian achieved a breakthrough with a battery pack that has an energy density of 360 Wh/kg. This will allow a 90-passenger plane to fly up to 800 km. This advance opens the door to larger and more efficient electric aircraft.
First electric passenger planes
The first commercial electric passenger planes are almost ready to take to the skies. Companies such as Eviation Aircraft have developed their Alice aircraft, which will be delivered to customers such as DHL in 20242. This marks an important step towards electrifying short-haul flights.
National and International Initiatives
In the Netherlands, a roadmap has been drawn up to electrify short-haul small aviation by 2026. This initiative, supported by the Ministry of Infrastructure and Water Management, focuses on certifying electric aircraft and adapting infrastructure at airports3. These efforts are crucial to reduce aviation’s CO2 emissions and achieve a more sustainable future.
Challenges and future prospects
While progress is impressive, challenges remain. Developing more efficient batteries, certifying new aircraft models, and adapting infrastructure remain key concerns. However, with current technological developments and growing industry-government cooperation, a future with electric flying seems increasingly feasible.
Developments in 2024 show that electric flying is no longer a distant dream, but a near reality. With continued innovations and cooperation, we can look forward to a more sustainable aviation industry that contributes to reducing global CO2 emissions.
Electric aircraft offer significant noise reduction benefits compared to traditional aircraft.
Reduction of noise pollution
Quieter than conventional aircraft: Electric aircraft use electric motors that are much quieter than traditional internal combustion engines. This results in a significant reduction in noise produced during take-off and landing.
Less Mechanical Noise: Since electric aircraft have fewer moving parts, they also produce less mechanical noise. This contributes to a quieter flight experience.
Air resistance: Although electric motors are quieter, air resistance can still cause noise. However, this noise is usually less intense than that of traditional aircraft.
Researchers continue to work on further noise reduction by optimising aerodynamics and using sound-insulating materials.
