Embraer and Rolls-Royce successfully test engines powered by 100% sustainable aviation fuel.

Embraer and Rolls-Royce have recently conducted groundbreaking tests on jet engines powered exclusively by Sustainable Aviation Fuel (SAF).

Embraer successfully tested a Phenom 300E and Praetor 600 with the engines on the right side of the aircraft powered by 100% or “neat” SAF while the left engines ran on jet-A.

Rolls-Royce tested two engines on 100% SAF: its Pearl 15 engine, which powers Bombardier’s Global 5500 and 6500 aircraft, and its Pearl 10X used in Dassault’s ultra-long-range Falcon 10X.

“This achievement is an important milestone in our journey toward net-zero carbon emissions by 2050 and demonstrates our commitment to sustainability, our customers, and our stakeholders,” Embraer Executive Jets president and CEO Michael Amalfitano said.

Related, the world’s first transatlantic flight powered by 100% SAF will take place on November 28 pending regulatory approval. 

The test flights come as a new study by German’s research aeronautics research center said the use of SAF reduces not only lifecycle carbon emissions, but also ultrafine particle emissions that impact public health.
