Virgin Atlantic’s historic flight on 100% Sustainable Aviation Fuel (SAF) took off from London Heathrow to New York JFK yesterday, demonstrating the capability of SAF as a safe drop-in replacement for fossil-derived jet fuel, compatible with today’s engines, airframes and fuel infrastructure.
The company says the flight marks the culmination of a year of radical collaboration and that SAF has a significant role to play in the decarbonization 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.
Currently, 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.
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. To achieve Net Zero 2050, the innovation and investment needed across all available feedstocks and technologies must be harnessed to maximize SAF volumes as well as continuing the research and development needed to bring new zero emission aircraft to market.
Virgin Atlantic states it is committed to finding more sustainable ways to fly, on its flightpath to Net Zero 2050, taking action across every part of the journey. Already operating one of the youngest and most fuel and carbon efficient fleets in the sky, Flight100 builds on the airline’s 15-year track record for leading on development of SAF at scale. Collectively, industry and government must go further, to create a UK SAF industry and meet aviation’s 10% SAF by 2030 target, capitalizing on the significant social and economic benefits it will bring – an estimated contribution of £1.8 billion in Gross Value Added to the UK and more than 10,000 jobs.
The airline acknowledged the SAF Grand Challenge President Biden set in 2021 for the US, promising the adoption of 3 billion gallons of SAF by 2030. Alongside the Inflation Reduction Act, the US government’s commitments to stimulate private investment into the US SAF industry reinforce the importance of close collaboration within the industry and globally to achieve emissions reductions targets.
Shai Weiss, Chief Executive Officer, 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 decarbonizing 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 is 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.”
