Rolls-Royce Achieves Milestone: 100% SAF Tests on Pearl Engines

Rolls-Royce recently achieved a groundbreaking milestone in its sustainability journey, completing a series of tests using 100% sustainable aviation fuel (SAF) on its Pearl 15 and Pearl 10X business aviation engines. These engines power prominent aircraft, including Bombardier's Global 5500 and 6500 as well as Dassault's Falcon 10X.

Notably, the tests demonstrated not only SAF compatibility but also the environmental benefits of SAF. Back-to-back tests with Jet A-1 and SAF on the same Pearl 10X engine revealed cleaner combustion and significantly lower levels of non-volatile particulate matter, all contributing to a reduction in emissions. This achievement aligns with Rolls-Royce's commitment to play a leading role in the industry's journey towards net-zero flight by 2050.

The SAF used in these tests, known as HEFA (Hydro-processed Esters and Fatty Acids) SAF, is derived from sustainable waste-based feedstocks, promising an 80% reduction in net CO2 lifecycle emissions compared to conventional jet fuel.

Rolls-Royce's current engine portfolio for large civil and business jet applications has demonstrated the capability to operate with 100% SAF, setting the stage for advancing this eco-friendly fuel toward certification. By the end of 2023, Rolls-Royce aims to prove that all its in-production Trent and business aviation engines are fully compatible with 100% SAF.

Dr. Dirk Geisinger, Director of Business Aviation at Rolls-Royce, emphasizes the importance of sustainable aviation fuels in decarbonizing long-haul flights. The outstanding environmental performance of the Pearl family of engines is already setting new standards in the ultra-long-range corporate jet market. This achievement is a testament to Rolls-Royce's dedication to a more sustainable future for business aviation and the broader aviation community, contributing to a cleaner and greener aviation industry.
