Cleaner Skies: ECLIF3 study of Airbus demonstrates significant reduction in No-CO2 emissions with sustainable aviation fuel (PURE). Airbus press photo
A pioneering study has shown positive results for the aviation sustainability thanks to the use of SAF. The program ECLIF3, carried out by a consortium that includes Airbus, Rolls-Royce, the German Aerospace Center (DLR) and SAF producer Neste, analyzed the impact of fuel use 100% SAF on both engines of an Airbus A350 commercial airliner.
Good environmental results with the use of SAF
Compared to fuel Jet A-1 conventional, the use of PURE 100% pure demonstrated a significant reduction in soot particle emissions and ice crystal formation in the condensation trails (contrails). In-flight measurements showed a decrease in 56% in the number of ice particles per unit of PURE consumed. Global climate simulations carried out by DLR estimate a reduction of at least one 26% on the overall climate impact of contrails when using SAF at 100%.
These results indicate that the PURE not only contributes to the reduction of CO2 emissions throughout the fuel life cycle, but also addresses effects unrelated to the CO2 aviation, like the formation of contrails. This represents a significant step towards a more sustainable aviation industry..
The research team has published their findings in the scientific journal Atmospheric Chemistry & Physics (ACP) of Copernicus, as part of a peer-reviewed scientific process. The program ECLIF3, which also includes researchers from the National Research Council of Canada and the University of Manchester, performed in-flight emissions tests and associated ground tests in 2021.
It is an important advance, although many regulatory issues remain pending, but above all the economic production of alternatives to fossil fuel.
