The Historic Transatlantic Flight on 100% Sustainable Aviation Fuel: Q&A With Virent Leaders

Virent’s President & General Counsel Dave Kettner and Vice President of Strategy & Business Development Bob Rozmiarek, join Richard Branson, the founder of Virgin Atlantic, the historic flight crew, and Virgin Atlantic’s other Flight100 partners. (Photo provided by Virgin Atlantic) On Tuesday, Nov. 28, Virgin Atlantic operated the world’s first transatlantic flight on 100% sustainable aviation fuel (SAF) by a commercial airline. The Boeing 787, using Rolls-Royce Trent 1000 engines, was fueled by a blend that included BioForm® synthesized aromatic kerosene (SAK) made by Virent, a subsidiary of Marathon Petroleum Corp. BioForm SAK is a critical ingredient that enabled the flight to be powered without any petroleum-based fuel. It was just the latest of a string of successful demonstration flights that Virent has helped make possible – others have included United Airlines, Bell Helicopter, Emirates Airline, and Gulfstream. We spoke with Virent President and General Counsel Dave Kettner and Vice President of Strategy and Business Development Bob Rozmiarek, both of whom were on the flight. Q: First, what exactly did Virent contribute to this flight, and why is it important? Dave Kettner: Our BioForm® SAK provided a critical component that made this flight possible. Most sustainable aviation fuel, or SAF, has to be blended with petroleum fuel to work in today’s jet engines. This is because SAF generally consists of paraffinic compounds but lacks the aromatics of petroleum-based jet fuel. BioForm® SAK, made out of plant sugars, is almost entirely aromatics, and so when we blend it with paraffinic SAF, we end up with a jet fuel that’s 100% bio-based and has the right composition to work in jet engines without making any modifications. In other words, it’s a “drop-in” equivalent to petroleum fuel. Q: How did Virent become involved in this flight? What other companies were involved? Bob Rozmiarek: We have been engaged in previous 100% drop-in SAF demonstrations with various engine manufacturers. The main interaction for this project started through contacts the team had at Rolls Royce. We started talking directly to Virgin Atlantic about a year ago. They quickly saw that our SAK blended with HEFA (hydroprocessed esters and fatty acids) would be the best way to achieve a transatlantic flight on 100% SAF. With the paraffinic fuel made out of waste fats by Air bp, and our bio-based aromatics made from plant sugars, Air bp was able to blend a fuel that Rolls Royce, the engine manufacturer; Boeing, airframe manufacturer; and Virgin, the airline operator, could test and agree on.
