Virgin Atlantic's historic flight on 100% Sustainable Aviation Fuel (SAF) takes off from London Heathrow to New York JFK today, marking the culmination of a year of radical collaboration, to demonstrate the capability of SAF as a safe drop-in replacement for fossil-derived jet fuel.
The fuel, made from waste products, delivers CO2 lifecycle emissions savings of up to 70%, whilst performing like the traditional jet fuel it replaces.
While other technologies such as electric and hydrogen remain decades away, SAF can be used now. Today, SAF represents less than 0.1% of global jet fuel volumes and fuel standards allow for just a 50% SAF blend in commercial jet engines. Flight100 will prove that the challenge of scaling up production is one of policy and investment, and industry and government must move quickly to create a thriving UK SAF industry.
The SAF used on Flight100 is a unique dual blend; 88% HEFA (Hydroprocessed Esters and Fatty Acids) supplied by AirBP and 12% SAK (Synthetic Aromatic Kerosene) supplied by Virent, a subsidiary of Marathon Petroleum Corporation. The HEFA is made from waste fats while the SAK is made from plant sugars, with the remainder of plant proteins, oil and fibres continuing into the food chain. SAK is needed in 100% SAF blends to give the fuel the required aromatics for engine function.
Sir Richard Branson, Founder, Virgin Atlantic said: "The world will always assume something can't be done, until you do it. The spirit of innovation is getting out there and trying to prove that we can do things better for everyone's benefit.
