Willis Lease Finance Corporation Chooses Wilton International for Major Sustainable Aviation Fuel Project

COCONUT CREEK, Fla., Oct. 02, 2025 (GLOBE NEWSWIRE) -- Willis Lease Finance Corporation (NASDAQ: WLFC) (“WLFC” or the “Company”), the leading lessor of commercial aircraft engines and global provider of aviation services, announced today that its subsidiary, Willis Sustainable Fuels (UK) Limited (“WSF”), has selected Wilton International in Teesside, a site owned and operated by Sembcorp Utilities (UK) Limited, as the location for its Sustainable Aviation Fuel (SAF) project. The new facility aims to produce 14,000 tonnes of SAF annually beginning in 2028 and is expected to deliver in excess of an 80% reduction in greenhouse gas emissions compared to conventional jet fuel.

“Wilton International offers the strategic location and world-class infrastructure necessary for the next generation of SAF production,” said Dr. Amy Ruddock, SVP Strategy, Sustainability and Transformation, at Willis Lease Finance Corporation. “Our selection of Wilton International underscores the pivotal role Teesside will play in the UK’s energy transition. By leveraging this site’s already renowned capabilities and collaborating with our technology and construction partners, we are advancing the UK’s leadership in sustainable aviation and supporting the creation of a robust local supply chain.”

It was recently announced that WSF’s project was awarded a £2.9 million grant from the UK Department for Transport’s Advanced Fuels Fund to support the project from July 2025 to March 2026.

The plant intends to convert sustainable biomethane, sourced from waste, into aviation fuel. WSF is collaborating with Johnson Matthey and Axens as technology partners, with McDermott leading the engineering. The initiative is projected to generate approximately 50 highly-skilled, permanent jobs, with a further 200 roles during construction.

“We are delighted that WSF has chosen Wilton International for its SAF project, which aims to accelerate the UK’s net-zero journey,” said Mike Patrick, CEO of Sembcorp Energy UK. “Our site provides vital infrastructure, reliable energy and integrated utility services essential for delivering large-scale, low-carbon projects. This partnership reinforces our commitment to enabling the UK’s energy transition and strengthens Wilton International’s strategic proposition in supporting industrial decarbonization.”
