Virgin Atlantic’s historic flight on 100% Sustainable Aviation Fuel (SAF) has taken off from London Heathrow to New York JFK, demonstrating the capability of SAF as a safe drop-in replacement for fossil derived jet fuel.
SAF has a significant role to play in the decarbonisation of long haul aviation, and pathway to Net Zero 2050.
The fuel, made from waste products, delivers CO2 lifecycle emissions savings of up to 70%, whilst performing like the traditional jet fuel it replaces.
SAF currently makes up less than 0.1% of global jet fuel volumes and fuel standards allow for just a 50% SAF blend in commercial jet engines.
SAF Flight100
As well as proving the capabilities of SAF, Flight100 will assess how its use affects the flight’s non-carbon emissions with the support of consortium partners ICF, Rocky Mountain Institute (RMI), Imperial College London and University of Sheffield.
The research will improve scientific understanding of the effects of SAF on contrails and particulates and help to implement contrail forecasts in the flight planning process. Data and research will be shared with industry, and Virgin Atlantic will continue its involvement with contrail work through RMI’s Climate Impact Task Force, which is part-funded by Virgin Unite.
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.
Virgin Atlantic net zero
To achieve Net Zero 2050, the innovation and investment needed across all available feedstocks and technologies must be harnessed to maximise SAF volumes as well as continuing the research and development needed to bring new zero emission aircraft to market.
Shai Weiss, CEO of Virgin Atlantic, said: “Flight100 proves that Sustainable Aviation Fuel can be used as a safe, drop-in replacement for fossil-derived jet fuel and it’s the only viable solution for decarbonising long haul aviation.
“It’s taken radical collaboration to get here and we’re proud to have reached this important milestone, but we need to push further. There’s simply not enough SAF and it’s clear that in order to reach production at scale, we need to see significantly more investment.
“This will only happen when regulatory certainty and price support mechanisms, backed by Government, are in place. Flight100 proves that if you make it, we’ll fly it.”
Sir Richard Branson, founder of 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.
“Virgin Atlantic has been challenging the status quo and pushing the aviation industry to never settle and do better since 1984. Fast forward nearly 40 years, that pioneering spirit continues to be Virgin Atlantic’s beating heart as it pushes the boundaries from carbon fibre aircraft and fleet upgrades to sustainable fuels.
“I couldn’t be prouder to be onboard Flight100 today alongside the teams at Virgin Atlantic and our partners, which have been working together to set the flight path for the decarbonisation of long-haul aviation.”
Transport Secretary Mark Harper said: “Today’s historic flight, powered by 100% sustainable aviation fuel, shows how we can both decarbonise transport and enable passengers to keep flying when and where they want.
“This Government has backed today’s flight to take-off and we will continue to support the UK’s emerging SAF industry as it creates jobs, grows the economy and gets us to Jet Zero.”
