In Finland, Neste and Lufthansa report they are satisfied with the results of their renewable aviation fuel trial, used on a total of 1,187 flights between Frankfurt and Hamburg last year and one intercontinental flight between Frankfurt and Washington D.C. this year.
Factors including fuel quality, aircraft performance, and fuel storability were studied. The two companies found that the aircraft and their engines performed excellently. The condition of the combustion chambers, turbines, and fuel systems of their engines was exemplary both during and at the conclusion of the trial. No signs of damage or corrosion were detected in the aircrafts’ fuel tanks, and longer-term storage was not shown to have any negative impact on fuel quality. Usage of NExBTL fuel resulted in 1% lower fuel consumption compared to regular fossil jet fuel.
