Det kommersiella elflyget– verklighet eller dröm: En litteraturstudie över elflygets utsikter


The purpose of this report has been to conduct a literature study to investigate the possibilities for electrifying commercial electric aircraft. Most of the report discusses future battery technology, which is a prerequisite for electrification. We show that the capacity of today’s dominant battery technology, the lithium-ion batteries, is limited. To achieve the energy density required for commercial electric aircraft, new, yet to be commercialized, battery technology is needed. Possible alternatives include lithium-sulfur and lithium-air batteries.

Today’s lithium-ion battery technology enables electric flight of up to four passengers at a distance of at most 300 km. A tripling of today's cell-specific energy to about 800 Wh/kg with a pack-efficiency of 80 percent would allow flights of up to about 1,100 km with an aircraft with 190 passengers in the middle of the century.

The remaining challenges for electric aviation are many. In addition to battery capacity, these include flight speed, the development of more efficient electric aircraft engines, battery costs and the need to intensify research and development of aircraft design. Furthermore, it is important that consumers have confidence in the safety of electric aircraft. Access to the minerals needed for battery production must be assured. Finally, aircraft have a long life span and the system is therefore sluggish.

The study’s conclusion is that large, fully electrified flight is far in the future, if it ever succeeds. On the other hand, we see the potential for a new market for smaller regional flights. Depending on the policy instruments that are directed at the electric aircraft, it could fill a market niche that has largely disappeared today - flights with smaller aircraft to small airports.

Unique knowledge compilation on microplastics from road traffic

Although we know that tyre and road surface wear generates significant emissions of microplastic particles, knowledge about them is very limited. This is the conclusion of a report issued by the Swedish National Road and Transport Research Institute (VTI).


Measures for infrastructure climate adaptation requires prioritisation

The effect of climate change will result in more extreme weather events causing for example increased risk of floods, and landslides, which will result in great costs to society. Therefore, society needs to prepare for the consequences brought on by climate...


Increased interest in train simulators

VTI has developed a train simulator that has become a valued tool in train driver education and research on how simulators can be used to improve railway technology.


Self-driving Buses in Linköping Part of the EU Project SHOW

The benefits of self-driving vehicles for people with disabilities are one of the focus area for a recently launched EU project linked to self-driving buses in Linköping, Sweden.


Young people's travel habits are important for the transition of the transport system

The transport system is facing a number of challenges due to its negative impact in areas such as the climate, equality and fairness. In a recent report, researchers highlight the voices of young people to get their thoughts on the field of transport.


Connected vehicles solve parking problems

Vehicles circulating in the city centre in search of a free parking space is a growing problem. A cloud service that tracks the traffic situation and the availability of free parking spaces could reduce both traffic and congestion.
