Key Takeaways:

  • Rolls-Royce successfully completed tests of its Pearl 15 and Pearl 10X business aviation engines running on 100 percent Sustainable Aviation Fuel (SAF).
  • The tests demonstrated SAF's compatibility and significant environmental benefits, including an 80 percent reduction in net CO2 life cycle emissions and cleaner burning with lower particulate matter.
  • Derived from waste-based feedstocks, the SAF used in the tests contributes to Rolls-Royce's goal of achieving net-zero flight by 2050.
  • These successful test results will help accelerate SAF's certification and its role in decarbonizing long-haul flight.

Rolls-Royce said it successfully completed a series of tests of its Pearl 15 and Pearl 10X business aviation engines using 100 percent sustainable aviation fuel, or SAF.

The Pearl 15, which is the first member of the Pearl engine family, powers the  Bombardier Global 5500 and 6500 aircraft. The Pearl 10X will be used on the Dassault Falcon 10X, the company’s ultralong-range flagship.
