In this episode, we sit down with Alasdair Lumsden, co-founder of Carbon Neutral Fuels, to explore how taking a screwdriver to a VCR led to his time in tech entrepreneurship, which eventually ended up in the world of sustainable aviation fuel.

Alasdair walks us through the company's Power-to-Liquid e-SAF project, Project Starling — a commercial-scale facility planned for Workington, Cumbria, targeting 25,000 tonnes per year of SAF by 2031.

We dig into the nuts and bolts of CNF's technology stack — solid oxide electrolysis (with Topsoe), Fischer-Tropsch synthesis (Johnson Matthey's FT CANS process), and upgrading technology (Honeywell UOP) — and how CNF is integrating waste heat recovery to improve efficiency and unit economics.

Alasdair also explains the decision to skip the demo phase and go straight to commercial scale, why their CO2 sourcing strategy shifted from 100% direct air capture to a mix of biogenic sources, and how they secured a 2031 grid connection date by choosing Cumbria over more traditional industrial sites.

On the commercial side, Alasdair discusses how CNF has raised over £11 million to date — including £7.4 million from the UK Advanced Fuels Fund across two rounds — and is now mid-way through a £24 million Series A, targeting patient capital and strategic investors.

We also cover offtake strategy, the Revenue Certainty Mechanism, the hydrogen policy disconnect, and why Alasdair sees the UK's DFT as a genuine competitive advantage for SAF developers looking to de-risk before expanding internationally.

This week's episode sees Vinesh Sinha, CEO, FatHopes Energy, joins Oscar Henderson for a conversation on the SAF Podcast.

Vinesh Sinha dropped out of university in 2007, inspired by a Top Gear episode, and built FatHopes Energy into one of Southeast Asia's most sophisticated sustainable fuel feedstock operations — with a digital traceability platform years ahead of the competition.

In this episode, Vinesh talks feedstock aggregation, the realities of scaling a waste-oil supply chain across Southeast Asia, and why FatHopes Energy is now moving into SAF refining with a 300,000-tonne greenfield plant targeting operations by 2030.

Plus: the truth about POME and palm oil, why AI is the only way to solve traceability at scale, and why Vinesh thinks the SAF industry is dangerously underestimating three things — feedstock, infrastructure, and integrity.

This is a wide ranging conversation and one that digs into the critical components that is helping build Malaysia as a SAF global hub.

In this episode of The SAF Podcast, Oscar is joined by Shubhda Kaushik, managing director & chief executive officer, Alternative Energy Company, to explore what it really takes to move sustainable aviation fuel projects from ambition to final investment decision. Drawing on experience at Standard Chartered, Bain and McKinsey and Maersk, giving her a rounded perspective across finance, strategy and commercial practicality. Shubhda explains why capital for energy transition projects is not scarce, but selective — and why bankability must be built in from day zero.

The conversation also dives into Shubhda’s new book, The Decisive Decade - 2026 Volume I: A Practitioner's Manual - What will it take to win on bankability in the next phase of energy transition.

We explore the core bankability framework behind it: revenue certainty, infrastructure access, execution capability and risk allocation.

This is just volume I, so if you enjoyed this stay tuned for volume II for a check in on the energy transition's progress.

This is a practical discussion for SAF producers, airlines, investors, lenders and anyone trying to understand why so many projects look promising on paper but struggle to reach financial close.

This episode gives you a great introduction to what is explain at length in the book, which you can find here: https://www.amazon.co.uk/Decisive-Decade-Practitioners-bankability-transition/dp/B0GZHQR25T/ref=sr_1_1?crid=3MEKZBXCEA3ZB&dib=eyJ2IjoiMSJ9.ikEBk10suF88vWdw1KH_CcBNnz9j6PniHNHHDWsie_fENicXTm3b2WClyMPMQ4pLvgKL6EJah0NMTppyB8GMRvqW_nJ3SG99vgYueNEUz1I.rZjcjiPvwirmc57l23MD1XG5HYaUI2osS2EXQErFT6I&dib_tag=se&keywords=the+decisive+decade&qid=1778142508&sprefix=the+decisive+decad%2Caps%2C293&sr=8-1

Noaman Al Adhami, UK Country Head at Alfanar Projects, is this week's guest on The SAF Podcast.

He joins Oscar for a discussion into Lighthouse Green Fuels — one of the UK’s most closely watched sustainable aviation fuel (SAF) projects. We begin by looking at why Alfanar chose to initially focus SAF production in the UK and the decisions around site selection.

We then explore what it takes to develop a second-generation SAF project at scale, including the gasification and FT-SPK pathway, feedstock selection, carbon capture, project financing, and the role of the UK SAF mandate in creating the right conditions for investment.

Noaman also explains why Alfanar is starting with biomass and agricultural residues, how the project could evolve towards more challenging waste feedstocks, the ongoing Carbon Capture application they have recently submitted and how the project has been financed to this point and future plans for financing project construction.

If you want to understand the real-world challenges of scaling advanced SAF production in the UK, this is an episode you won’t want to miss.

In this episode of The SAF Podcast, Oscar is joined by Patrick Sieb, Managing Partner at Climate Tech Partners, for a conversation on what it really takes to finance and scale sustainable aviation fuel. From Series A climate tech investing to corporate-startup partnerships and the infrastructure challenges behind SAF production, Patrick shares a practical investor’s view on how promising technologies can move from early traction to commercial deployment.

Climate Tech Partners investment model is based on deep due diligence, originating from his time a Macquarie, with focus in Transport, Energy and Mining sectors.

We dive into a variety of topics including:

• How Climate Tech Partners approaches Series A climate tech investing and why that stage can be critical for SAF and other capital-intensive technologies
• Why bridging the “valley of death” remains one of the biggest challenges for deep tech and aviation decarbonisation startups
• How corporate relationships can help de-risk investments, including Climate Tech Partners’ work with Qantas and Airbus
• The practicalities of running a VC fund, raising capital from LPs and portfolio diversification
• What the dedicated sidecar investment vehicle means for aviation-focused climate technologies and SAF-related opportunities
• Why SAF scale-up depends on much more than strong technology, including the role of feedstock, infrastructure, energy and financing
• What investors are really looking for when assessing techno-economics, commercial traction and science risk
• Why climate tech is shifting from “moonshot” narratives to more pragmatic pathways focused on cost parity and bankability
• How Australia and the wider APAC region could fit into the future of sustainable aviation fuel production and aviation decarbonisation

Also another reminder that we are still accepting applications for the SAF Investor Deal of the Year awards. If you worked on a deal we would love for you to submit it via the following link: https://docs.google.com/forms/d/e/1FAIpQLScwrzV8VN8oqA6c-e0GMlgZmttTQ-U-1D9XxnOgeeQV-ITeiQ/viewform?usp=header

In this episode of The SAF Podcast, Oscar is joined by Nico Nicholas, Co-Founder and CEO of Zeero Group, for a discussion on the commercial and strategic realities of scaling the Hydrothermal Liquefaction SAF pathway. The conversation goes beyond the technical basics to look at how waste-to-fuel projects are financed, how they can be tailored to local infrastructure needs, and why collaboration across sectors may be essential if SAF is to scale at pace.

We dive into a variety of topics including:

• How ZEERO Group is approaching project development, with each facility structured around local waste streams, local infrastructure and location-specific business models
• Why combining waste management and fuel production could create a stronger commercial case for SAF-linked projects
• The financing logic behind these developments, including co-investment models, strategic partners and government-backed support mechanisms
• Why investor confidence and proof of delivery remain critical for emerging pathways looking to move from concept to commercial scale
• The role of certification timelines and regulatory processes in shaping how quickly new SAF pathways can enter the market
• Why scaling SAF may require much deeper collaboration between aviation, municipalities, tourism, shipping and energy stakeholders

This discussion picks up on some key themes from across the SAF industry so is well worth a listen if you are part of the growing ecosystem that is going o make commercial SAF production a global success. We also almost manage to go the whole episode without a crude joke/pun...almost!

We are also currently accepting applications for the SAF Investor Deal of the Year awards. If you have been involved in a financing deal in the last year, we would love to hear about it.

Kenneth Hill, BioCarbon Strategies joins us for this episode of The SAF Podcast as we knee deep in the alphabet soup of North American tax policy.

Ken brings unique insight as a former U.S. Department of Energy financing official who worked on projects like Montana Renewables and Gevo, combined with current experience vetting SAF projects and advising investors on bankability across the US, Canada, and emerging markets.

Key Topics Covered:

🇺🇸 US SAF Market Grade: From B+ (one year ago) to C+/B- today—a setback driven by policy uncertainty, funding challenges, and administration headwinds. Ken explains why the trajectory is shifting back toward optimism in 2026.

📋 The SAF Act (Securing America's Fuel Bill): A bipartisan proposal restoring the $1.75/gallon bonus credit, extending availability retroactively, and creating crucial market certainty. Why passage by November 2024 matters for stability and investment confidence.

🌾 Farm Bill SAF Support: How the 5-year agriculture bill (currently 3 years overdue) addresses feedstock supply chain enablement and USDA loan guarantees up to $250 million. The critical difference between supply-side support and direct financing.

💰 45-Z Clean Fuel Production Tax Credit: The shift from blender's credits to production credits—and why guidance from the U.S. Treasury expected by summer 2026 is critical to project financing.

🏛️ Investment Tax Credits vs. Production Tax Credits: Ken explains the investor preference for investment credits ($600M upfront on a $2B project) over production credits (ongoing incentives that risk expiration). Why the structure matters enormously for capital deployment.

🇨🇦 CANADIAN POLICY DEEP DIVE: The Biofuels Production Incentive as a bridge to help producers survive the shift from the US blenders credit to production credit. The $15 billion CAD Canada Growth Fund for green projects. Also, Ken explains the expected amendments for the Clean Fuel Regulations (CFR).

🔑 Permitting as the Bottleneck: The often-overlooked critical issue in both US and Canadian project development. Why streamlined permitting is essential for scaling—and how power generation permit timelines (6 years) exceed solar build times (24 months).

💼 Bankability Requirements in 2026: Why projects today need multiple stacks working simultaneously—price stack (credits + subsidies), offtake stack (airlines + carbon buyers), and feedstock stack.

🌍 Global Demand & Carbon Markets: Why voluntary corporate buyers are as critical as policy mandates. The mix needed: government incentives, mandates, voluntary carbon markets, and offtake diversity to derisk projects.

🚀 North American Momentum: Why 2026 is the pivotal year—with clarity on SAF Act, Farm Bill, 45-Z guidance, and Canadian CFR amendments all expected. The potential bounce-back from 2025's lull to accelerated deployment post-2027.
