In an era where environmental sustainability is not just a choice but a necessity, Virgin Atlantic’s Flight100, a trailblazing transatlantic journey from London Heathrow to New York JFK, marks a significant leap. What makes this flight extraordinary is its fuel – 100% Sustainable Aviation Fuel (SAF), a pioneering step towards decarbonizing long-haul aviation.
The Science and Significance of SAF
SAF, the fuel propelling Flight100, is more than just an alternative to fossil-derived jet fuel; it’s a beacon of hope for the aviation industry. Made from waste products, SAF promises up to 70% CO2 lifecycle emissions savings. This remarkable achievement in reducing environmental impact doesn’t compromise on performance; SAF operates just like the traditional jet fuel it seeks to replace. This compatibility with current engines, airframes, and fuel infrastructure paves a clear path to Net Zero by 2050.
Flight100 utilized a unique dual blend of SAF – 88% HEFA (Hydroprocessed Esters and Fatty Acids) and 12% SAK (Synthetic Aromatic Kerosene). HEFA comes from waste fats, while SAK, provided by Virent, a subsidiary of Marathon Petroleum Corporation, is derived from plant sugars. This blend ensures that not only do engines function seamlessly, but it also contributes positively to the food chain.
The Collaboration Behind the Milestone
This historic journey was the culmination of a year of radical collaboration among a consortium led by Virgin Atlantic. Key players included Boeing, Rolls-Royce, Imperial College London, University of Sheffield, ICF, and Rocky Mountain Institute, all partnering with the Department for Transport. This collective effort demonstrates a model for future advancements, where synergy among various sectors can lead to monumental results.
Virgin Atlantic’s Pioneering Role
Shai Weiss, CEO of Virgin Atlantic, underscores the importance of this milestone: “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.” This flight is not just an isolated accomplishment but a part of Virgin Atlantic’s ongoing commitment to sustainability, further evidenced by their 15-year track record in developing SAF at scale.

Rolls-Royce’s Vital Contribution
Rolls-Royce has played a pivotal role in this endeavor. Simon Burr, Group Director of Engineering, Technology & Safety, Rolls-Royce plc, stated: “We are incredibly proud that our Trent 1000 engines are powering the first ever widebody flight using 100% Sustainable Aviation Fuel across the Atlantic today.” This flight proves that there are no engine technology barriers to the use of 100% SAF, reinforcing Rolls-Royce’s commitment to net zero carbon emissions.
The Broader Impact and Future Prospects
Virgin Atlantic’s initiative is a call to action for both industry and government to further invest in and support the burgeoning SAF industry. The potential economic and social benefits are immense, with the prospect of contributing £1.8 billion in Gross Value Added to the UK and creating over 10,000 jobs.
SAF’s current global jet fuel volume share is less than 0.1%, and the fuel standards allow only a 50% blend in commercial jet engines. However, initiatives like Flight100 showcase the feasibility and necessity of increasing this percentage. The flight also serves as a platform for research, assessing non-carbon emissions and improving our understanding of SAF’s environmental impact.
Virgin Atlantic’s Flight100 is more than a pioneering flight; it’s a symbol of what can be achieved through innovation, collaboration, and a steadfast commitment to sustainability. It opens a promising chapter in aviation, where the skies we traverse can align with the environmental goals we strive to meet, paving the way for a cleaner, greener future in air travel.
