First in-flight study shows significant benefits of 100% SAF
The ECLIF3 study reveals that using 100% sustainable aviation fuel (SAF) reduces soot and contrail ice crystals, highlighting its potential to mitigate climate impacts.
In a groundbreaking study, the world's first in-flight examination of commercial aircraft using 100% sustainable aviation fuel (SAF) has shown promising results in reducing non-CO2 emissions. Conducted by Airbus, Rolls-Royce, the German Aerospace Center (DLR), and SAF producer Neste, the ECLIF3 study focused on an Airbus A350 powered by Rolls-Royce Trent XWB engines.
The findings revealed a 56% reduction in contrail ice crystals per mass of unblended SAF compared to conventional Jet A-1 fuel. This could significantly decrease the climate-warming effects of contrails. The DLR used global climate models to estimate a 26% reduction in radiative forcing due to SAF use.
Lowering both carbon footprints and contrail formation
Markus Fischer from DLR highlighted the dual benefits of SAF in lowering both carbon footprints and contrail formation. Mark Bentall from Airbus emphasized the scientific backing for SAF's role in decarbonizing air transport. The study also demonstrated that SAF could be used at higher concentrations than the currently approved 50%.
The research, published in the Copernicus journal Atmospheric Chemistry & Physics, marks a significant step towards climate-compatible aviation. The ECLIF3 program underscores the critical role of SAF in achieving net-zero CO2 emissions and reducing aviation's overall climate impact.
