In New Jersey, AIN reported that a newly released collaborative in-flight study using 100% sustainable aviation fuel showed a reduction in soot particles and formation of contrail ice crystals compared to using conventional jet A-1 fuel. The Emission and Climate Impact of Alternative Fuels (ECLIF3) study included the participation of Airbus, Rolls-Royce, the German Aerospace Center (DLR), and Neste, according to the report. According to the study, the number of ice crystals per mass of unblended SAF consumed was reduced by 56 compared to jet-A fuel, which could significantly reduce the climate-warming effect of condensation trails—better known as contrails. “SAF is widely recognized as a crucial solution to mitigate the climate impact of the aviation sector, both in the short term as well as the longer term. The results from the ECLIF3 study confirm a significantly lower climate impact when using 100% SAF due to the lack of aromatics in Neste’s SAF used, and provide additional scientific data to support the use of SAF at higher concentrations than currently approved 50%,” said Alexander Kueper, VP of renewable aviation business at Neste.
