Flying liquid hydrogen – the 2021 update

At the beginning of 2021 NLR initiated an ambitious project with a view to flying its HYDRA-2 drone using liquid hydrogen in a full composite tank by the end of 2022. As the end of this year approaches, the NLR project team looks back at the challenges faced and celebrates its achievements.

Blog: An addition to the sustainable development goals

On October 31st the 2021 United Nations Climate Change Conference (COP26) started in Glasgow. And the news is full of articles reminding us all, once again, the impact of all human activities on the climate and the desperate need to change. Criticism is raised against those participants who travelled to Glasgow by plane. As it happens more often this illustrates, the aviation sector is targeted as the “evil” industry.

Innovations in aviation to preserve the environment and the climate

The Dutch aviation sector is investing in clean and smart mobility. To do that, various consortiums under the auspices of the sector organisations LRN and NAG have submitted ten project proposals to the Netherlands Enterprise Agency, RVO. Royal NLR has played an essential role in that. Given the aim of improved sustainability in aviation, the sector wants to use these proposals to obtain access to the Mobility Fund. In concrete terms, the proposals range from applications of new lightweight materials and the use of digital techniques through to developing electrically powered flight and using greener aviation fuels.

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 may be sufficient. However, that depends heavily on the amount of excess renewable electricity allocated to the aviation sector.

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 first at Schiphol: the first time an electric plane lands there, recharges and sets off again for its next destination.

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.

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.
