- In-flight measurements from an A350 plane utilizing 100% sustainable aviation gas (SAF) present a big discount in soot particle emissions and formation of contrail ice crystals in comparison with utilizing standard aviation gas
- World mannequin simulations estimate 26% discount in contrails’ local weather influence when utilizing 100% SAF
Outcomes from the world’s first in-flight research of the influence of utilizing 100% sustainable aviation gas (SAF) in each engines of a business plane present a discount in soot particles and formation of contrail ice crystals in comparison with utilizing standard Jet A-1 gas.
The ECLIF3 research, wherein Airbus, Rolls-Royce, the German Aerospace Middle (DLR) and SAF producer Neste collaborated, was the primary to measure the influence of 100% SAF use to emissions from each engines of an Airbus A350 powered by Rolls-Royce Trent XWB engines and adopted by a DLR chase airplane.
In comparison with a reference Jet A-1 gas, the variety of ice crystals per mass of unblended SAF consumed was lowered by 56%, which might considerably scale back the climate-warming impact of condensation trails — also called contrails.
World local weather mannequin simulations, performed by DLR, had been used to estimate the change within the power stability in Earth’s ambiance — also called radiative forcing — by contrails. The influence of contrails was estimated to be lowered by not less than 26% with 100% SAF use in comparison with the Jet A-1 reference gas utilized in ECLIF3. These outcomes present that utilizing SAF might considerably scale back the local weather influence of aviation within the quick time period by lowering non-CO2 results similar to contrails, along with lowering greenhouse fuel emissions, similar to CO2 emissions over the life cycle of SAF when in comparison with utilizing fossil jet gas.
“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%,” stated Alexander Kueper, Vice President Renewable Aviation Enterprise at Neste.
”The outcomes from the ECLIF3 flight experiments present how using 100% SAF may help us to considerably scale back the climate-warming impact of contrails, along with reducing the carbon footprint of flying — a transparent signal of the effectiveness of SAF in the direction of climate-compatible aviation”, stated Markus Fischer, DLR Divisional Board Member for Aeronautics.
“We already knew that sustainable aviation fuels could reduce the carbon footprint of aviation. Thanks to the ECLIF studies, we now know that SAF can also reduce soot emissions and ice particulate formation that we see as contrails. This is a very encouraging result, based on science, which shows just how crucial sustainable aviation fuels are for decarbonizing air transport,” stated Mark Bentall, Head of Analysis & Know-how Programme, Airbus.
“Using SAF at high blend ratios will form a key part of aviation’s journey to net-zero CO2. Not only did these tests show that our Trent XWB-84 engine can run on 100% SAF, but the results also show how additional value can be unlocked from SAF through reducing non-CO2 climate effects as well,” stated Alan Newby, Rolls-Royce, Director Analysis & Know-how.
The analysis staff has reported its findings within the Copernicus journal Atmospheric Chemistry & Physics (ACP) as a part of a peer-reviewed scientific course of, and gives the primary in-situ proof of the local weather influence mitigation potential of utilizing pure, 100% SAF on a business plane. The ECLIF3 program, which additionally consists of researchers from the Nationwide Analysis Council of Canada and the College of Manchester, performed in-flight emissions assessments and related floor assessments in 2021.
