Sustainable alternatives to kerosene: the facts

1 minute read

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 plain and simple truth in a fact sheet called ‘Sustainable Alternatives to Kerosene’.

This is how the two parties are aiming to provide input to the lively social debate about making aviation greener. The NLR and TU Delft previously published a whitepaper about the most promising technological routes towards climate-neutral aviation by 2050.
