The tests will aim to confirm that unblended SAF makes a significant contribution to improving the environmental performance of gas turbine engines.

The SAF being used in the tests was produced by low-carbon fuel specialist World Energy in Paramount, California, sourced by Shell Aviation and delivered by SkyNRG. This unblended fuel has the potential to significantly reduce net CO2 lifecycle emissions by more than 75 per cent compared to conventional jet fuel, with the possibility of further reductions in years to come.

The ground tests will involve a Trent engine which also incorporates ALECSys (Advanced Low Emissions Combustion System) lean-burn technology.

In addition to supplying the SAF with SkyNRG, Shell Aviation is also providing Rolls-Royce with AeroShell lubricants for the ALECSys engine test programme.

Paul Stein, Rolls-Royce chief technology officer is quoted in the press release: “Aviation is a tremendous force for good, keeping the world connected, but we have to do that sustainably. These tests aim to show that we can deliver real emissions reductions. If SAF production can be scaled up – and aviation needs 500 million tonnes a year by 2050 - we can make a huge contribution for our planet.”

Anna Mascolo, President, Shell Aviation, said: “For over 100 years, Rolls-Royce and Shell have worked together to drive aviation’s progress. This collaboration brings us one step closer to decarbonizing Aviation. As well as the SAF, Shell Aviation will provide offsets using nature-based solutions to make the test net zero emissions, reinforcing how multiple measures are essential if aviation is to achieve net zero carbon dioxide emissions.”
