Production of sustainable aviation fuels in the Netherlands might not meet demand

The amounts of sustainable aviation fuels being produced by 2050 from the biobased feedstocks that will be available in the Netherlands can only meet a fraction of the anticipated fuel demand. The supply potential for synthetic kerosene, produced using CO2 that has been recycled or captured from the atmosphere and renewable electricity, is larger and […]

Electric flight is taking off in the Netherlands

What do you need to consider when flights are electric? Royal NLR recently acquired a two-seater electrically powered research aircraft. Now it’s time to get some flying hours under our belt and gain more experience. The aircraft will make various flights throughout the Netherlands with stopovers at several airports. One thing this will produce is a […]

Blog: Fit for 55!

Last Wednesday, the European Commission presented ‘Fit for 55%’, a package for the practical implementation of the EU’s Green Deal. In a previous blog post, I looked at a much-repeated misconception concerning kerosene tax. Now I wish to consider the question of to what extent the new package can boost the sustainability of the aviation industry. Back […]

Blog: Kerosene tax: what exactly is the deal?

As part of the set of measures proposed by the European Commission to meet the 2030 CO2 reduction target – ‘Fit for 55%’ – the topic of kerosene tax is back on the political agenda. In this blog, I will try to clarify the laws and regulations on this matter and correct a common misunderstanding. […]

Centralised information about aircraft noise

Aircraft noise leads to a lot of discussions in the Netherlands. To keep not only the general public but also politicians and policymakers properly and objectively informed, RIVM (the National Institute for Public Health and the Environment), NLR and To70 have bundled together relevant information about this topic and placed it on a new website, […]

World’s largest known thermoplastic aircraft structure (MFFD/STUNNING)

An 8.5 meter long fuselage skin made of thermoplastics has been produced by automated fibre placement. Within the MFFD framework Royal NLR, together with GKN Fokker (lead), TU Delft, and Germany’s Diehl, have taken on their own project called STUNNING. Their goal is to demonstrate and validate how the use of composites, namely thermoplastics, can […]

Sustainable alternatives to kerosene: the facts

Why are CO2 emissions from flying still rising although planes are becoming more economical? What would be a logical distance for flying battery-powered electric aircraft? What techniques are there for flying on hydrogen? The facts, plain and simple. Royal NLR and Delft University of Technology answer various burning questions about sustainable aviation by laying out the […]

SUSTAINair is investing in circular aviation for the green transition

The SUSTAINair project is investigating and developing solutions for sustainably using raw materials and improving the performance of aircraft. This Horizon 2020 project, which recently got off the ground, is aiming at the same time to achieve circular aviation by drastically reducing the waste and material costs throughout the lifecycle of the aeroplane. Because of the […]

Blog: Trust in aviation is about more than noise nuisance alone

The past year has been an exceptional period for aviation: the outbreak of the coronavirus pandemic has sharply reduced air travel world-wide. At Schiphol Airport, the number of flights has fallen by 54% in comparison with 2019. Little or no air traffic means less exposure to aircraft noise. This is a situation that is unheard […]
