UK-based global major industrial technology group Rolls-Royce has carried out the first trials using 100% sustainable aviation fuel (SAF) in an engine developed for business jets. The tests were carried out at the group’s facility at Dahlewitz, in Germany, and came just weeks after it had successfully used unblended SAF in ground tests using a Trent 1000 engine (designed for widebody airliners) at Derby in the UK. The SAF used in these tests was produced by a US specialist low-carbon fuel company, World Energy, based in Paramount in the state of California. It was sourced by global major energy company Shell and delivered by SkyNRG. This SAF, used unblended, could cut net lifecycle carbon dioxide emissions by more than 75%, with the potential for yet greater reductions in the future, in comparison to conventional jet fuels.
