Rolls-Royce Trent XWB and GE GEnx Engines Burn 100% SAF but Lack Certification

Modern widebody jet engines have reached the pinnacle of thermodynamic engineering, capable of producing immense thrust while burning cleaner alternative fuels. Manufacturers like Rolls-Royce and GE Aerospace have repeatedly shown that their flagship powerplants, including the Trent XWB and the GEnx , can operate perfectly on 100% sustainable aviation fuel during controlled demonstrations. If an airline were to attempt to pump unblended synthetic fuel into a commercial passenger flight today, the aircraft would be legally grounded.
