Willis Sustainable Fuels Progresses Teesside SAF Project

COCONUT CREEK, Fla., March 31, 2025 (GLOBE NEWSWIRE) -- (NASDAQ: WLFC) (“WLFC” or the “Company”), the leading lessor of commercial aircraft engines and global provider of aviation services, today announced that its subsidiary, Willis Sustainable Fuels (UK) Limited (“WSF”), has entered into license and engineering agreements with two global leaders in sustainable technology, Johnson Matthey and Axens. These partnerships significantly advance WSF’s sustainable aviation fuel (SAF) project in Teesside, Northeastern England. WSF is targeting Q1 2028 to begin commercial operations at its SAF production facility, with an anticipated annual production capacity of 14,000 tonnes (equalling approximately 50,000 litres a day) of SAF.

“Through this collaboration, WSF will leverage Johnson Matthey’s and Axens’ market-leading technologies to support the production of SAF at our facility in Teesside, UK,” said Amy Ruddock, Senior Vice President, Sustainable Aviation & Corporate Development of WLFC. “Working with industry leaders will allow us to accelerate progress toward our vision for a cleaner, more sustainable future.”

This project received a grant from the UK Department for Transport’s Advanced Fuels Fund and represents an important step towards the UK government's 2050 net-zero target and its goal of having five commercial-scale SAF plants under construction by 2025. WSF is currently executing the detailed design phase of the project. McDermott will perform early engineering, procurement, and construction (EPC) related services for the project.

“Our FT CANS™ technology was developed in partnership with bp and revolutionizes the sustainable fuel sector by enabling production at commercial scale. We look forward to working with Willis Sustainable Fuels on this innovative project that will benefit the UK and beyond,” said Alberto Giovanzana, Managing Director - Licensing at Johnson Matthey

“Axens is honored to be chosen as a partner in this pivotal energy transition project to support the emergence of the advanced SAF market in the UK. We are dedicated to accompanying Willis every step of the way, ensuring the successful implementation of innovative solutions that drive sustainable progress,” said Jacques Rault, Executive Vice President Technology & Technical Support of Axens.

The project’s technology is intended to produce 100% SAF that can be seamlessly blended with conventional jet fuel for immediate use with existing commercial aircraft engines. The fuel produced is projected to offer greenhouse gas emissions savings of approximately 80% compared to today’s fuels.

WSF remains committed to the aviation industry’s transformation to a more sustainable future by investing in, developing and producing scalable solutions to decarbonize aviation. For more information on WSF, visit .
