Avioxx, SolydEra report breakthrough in waste-to-power SAF production

UK-based sustainable aviation fuel (SAF) company Avioxx said it has successfully demonstrated electricity generation with a bespoke SOFC system, using simulated, waste-derived syngas as a feedstock in partnership with Italian solid oxide technology company SolydEra.

The companies used using waste-derived syngas for electricity generation using SolydEra’s SOFC technology opening the door to dramatic efficiencies when integrated into Avioxx’s SAF production process.

“This breakthrough doesn’t just power a process; it solves a waste disposal challenge. With the volume of nonrecyclable waste in the UK alone, there’s potential to meet up to 50% of the country’s aviation fuel demand. This is circular energy in action,” said SolydEra CEO Dr. Alexander Liberov.

Syngas, a mixture of carbon monoxide and hydrogen, is produced from household waste and is used in the patented Avioxx process to make SAF.

The demonstration took place at Avioxx’s Advanced Fuels Facility in Runcorn, UK, where a pilot SOFC unit has been operating periodically since February 2025.

“This is a real breakthrough at the core of the Avioxx system,” said Chris Hancock, CEO of Avioxx. “By generating electricity within the SAF process using gas made from waste, we remove the need to purchase external electricity and believe we can make sustainable fuel cost-competitive with fossil when operating at scale.”

The Avioxx programme will see the two companies working together to design a full-scale, integrated SOFC module for commercial deployment in Avioxx’s future SAF refineries.

Avioxx’s first large-scale production facility is planned to begin construction in 2026.
