The final episode of 2025 brings a fresh perspective as The SAF Podcast welcomes its first Academic, Alon Lidor from the National Laboratory of the Rockies (formerly the National Renewable Energy Laboratory).

Alon shares his fascinating journey from aerospace engineering to sustainable aviation fuel research, including his work on solar-driven thermochemical processes at ETH Zurich and his current role at NLR. The conversation explores his groundbreaking research on chemical looping technology for syngas production, which promises to overcome traditional reverse water-gas shift reaction limitations and significantly reduce downstream separation costs in SAF production.

A highlight of the episode is Alon's insights from interviewing over 80 industry stakeholders through the Department of Energy's Energy I-Corps program. He reveals findings about the SAF industry's biggest challenges, including funding and bankability concerns that outweigh technical barriers, and the underestimated complexity of scaling pilot plants to commercial production.

The discussion examines the crucial relationship between academia, national laboratories, and industry in advancing sustainable aviation fuel technologies. Alon explains how national labs like NLR provide essential infrastructure and expertise to help early-stage companies de-risk their technologies, offering capabilities that would be prohibitively expensive for startups to build independently.

Listeners gain valuable insights into techno-economic analysis, regional policy differences between US incentive-based approaches and European mandate-driven frameworks, and the timeline for Alon's three-year research project developing next-generation SAF production technology.

Thank you so much to everyone that has listened over the last year and some exciting things to come in 2026!

On this week's episode of The SAF Podcast Chris Hancock, Avioxx joins Oscar to share their waste-to-fuel technology and their UK project development strategy.

Chris begins by sharing his journey from fintech entrepreneur to cleantech innovator, explaining some of the parallels between the early days of fintech and today's nascent SAF industry.

We also dive into Avioxx's off-grid approach integrating Fischer-Tropsch reactors with solid oxide fuel cells, enabling the plant to generate its own electricity and potentially achieve an 80% reduction in electricity costs. The result aims to tackle the two hardest cost drivers in SAF—purchased power and hydrogen balance—while building a real circular economy around waste.

Integrating AI and digital infrastructure is a fulcrum of Avioxx's expansion to accelerate design timelines, reduce costs, and mitigate risks. Chris explains how this feeds into their UK focused expansion plans from a small scale demonstrator, to a mid-scale plant producing 5,000 tonnes per year, up to a 32,000 tonne per year facility consuming 300,000 tonnes of waste each year.

We finish by discussing capital raising, the pre-seed investment from Trailfinders and the current ongoing raise for their Series A-B rounds. Chris explains the types of capital they are looking to attract in the balancing of equity and senior debt.

In this episode of The SAF Podcast, host Oscar Henderson sits down with Hamid, Francis and Sergio from Nexen Biosystems to explore one of the most unconventional and interesting sustainable aviation fuel (SAF) feedstocks emerging today: tequila bagasse.

With what seems like every celebrity wanting to start a tequila brand. The market over recent years has boomed, creating an abundant amount of year round feedstock. Tequila production is tightly concentrated by denomination rules, so residues are steady, local, and available at favorable terms because they’re a disposal headache for distillers. Agave bagasse is pre-cooked and pressed during tequila making, which can reduce pre-treatment intensity compared to raw crop waste.

We dig into Nexen's strategy: 18 months of R&D at a Canadian lab to tune pre-treatment and conversion steps, followed by a Mexico-based pilot to validate logistics, contracts, and costs at scale. Along the way we talk policy reality—strong Canadian support for clean-tech research, Mexico’s push to manage tequila waste and align with global SAF goals.

We also discuss the challenge of raising capital in the R&D stage before building a demonstration and pilot plants. Finding investors that are comfortable with the risk profile all aspects of developing a SAF facility is crucial for Nexen as investors bring much more to the table than just capital.

Sit back, grab a tequila (think of the feedstock) and listen to this episode and find out about the potential of tequila bagasse as a feedstock and how Nexen are planning on utilizing it for SAF production.
