The SAF World Cup

The SAF World Cup

Getting fully behind World Cup fever, SAF Investor is running The SAF World Cup. Gathering experts from different countries, we will be running a knock out style bracket to find the most promising SAF country in the world. Decided by popular vote! Whether it is policies, access to capital, offtakers, feedstock access, infrastructure expertise all these will be key discussion points.  Join for a bit of World Cup fun alongside some serious discussion! Speakers include: Trevor Best, Syzygy Plasmonics - Brazil Philippe Haffner, Haffner Energy - France Jim Stonecipher, EdyMac - United States of America  Andrew Symes, OXCCU - England Izabela Santos, StratX Group - Sweden Listen to the full webinar on our podcast for some light but informative SAF competition.

Dan Sutton, Syntholene: Building on a volcano and betting on geothermal

In this episode, we sit down with Dan Sutton, CEO and co-founder of Syntholene, to explore their geothermally integrated synthetic fuel production technology currently being developed in Iceland. Dan explains why geothermal energy is such a compelling foundation for eSAF production, how Syntholene's solid oxide electrolyzer cell (SOEC) technology — integrated with Iceland's abundant heat and electricity — creates a step-change in hydrogen cost reduction, and why the company believes it can achieve unit economics competitive with fossil fuels without relying on perpetual subsidies.  We also explore the independent feasibility study conducted by notable alternative fuels sceptic Robert Rapier, whose findings validated Syntholene's scientific fundamentals while identifying the integration and construction risks that Dan openly acknowledges — and explains how his team is managing them. The conversation broadens into project development philosophy, the replicability of the Iceland model in geothermally active regions globally and how you manage earthquake and volcano risk, Iceland's strikingly low-bureaucracy environment for infrastructure permitting, and a frank debate on whether European eSAF policy is addressing the real problem — or papering over a fundamental unit economics challenge. We close with Syntholene's unconventional but deliberate choice to go public on the TSX Venture Exchange — and why Dan believes building in public, with a diversified investor base, gives the company more control over its destiny than the traditional venture capital route.

Mikala Grubb, Topsoe: The 100th episode and tech behind a third of the world's SAF

For the 100th episode of The SAF Podcast, we're joined by Mikala Grubb, Senior Vice President of Technologies, Topsoe — one of the world's leading catalysis and technology companies, whose technology produces an estimated third of all the SAF available globally today. We start with feedstocks — why the constraints on used cooking oil and animal fats are tightening, what a post-2030 feedstock crunch could look like, and which next-generation feedstock options (from intermediate crops and municipal solid waste to tire-derived feedstocks) are genuinely gaining traction versus those still some way from commercial reality. We then turn to technology: how Topsoe's HydroFlex HEFA technology became the commercial backbone of today's SAF industry, the role co-processing can play as a pragmatic stepping stone, and why Mikala's advice to developers facing ASTM certification delays is simple — start with renewable diesel and switch when certified. We also explore the ESAF pathway, the importance of the Topsoe-DLR-Sasol demonstration plant currently under construction, and why Topsoe is ready to sign full commercial-scale ESAF contracts today. Throughout, a clear theme emerges: successful SAF projects are built on feedstock security, offtake certainty, the right partner ecosystem, and a willingness to be pragmatic.  Happy 100th, The SAF Podcast. Thank you to all the guests we have had over the last 100 episodes and to everyone that has listened!

Adam Forsyth, Longspur Capital: Khaki is the new green

Adam Forsyth, founder of Longspur Capital joins for the latest episode of The SAF Podcast. A leading voice in clean energy investment, we explore how sustainable aviation fuel (SAF) fits into the broader energy transition — and what it will take to unlock the capital needed to scale it. Adam draws on decades of experience across equity research, corporate finance, and clean energy advisory to unpack the structural financing challenges unique to SAF: the offtake mismatch, the difficulty of securing long-term airline contracts, and why the "alignment problem" is one of the biggest barriers to reaching final investment decision on advanced fuel projects. We explore how geopolitical shifts — particularly the fracturing of the post-WWII trade consensus — are reshaping energy investment, introducing a "security premium" that may, in some ways, work in SAF's favour. We also discuss the evolving role of carbon dioxide removal credits, the lessons SAF developers can draw from analogous sectors like grid-scale batteries and green hydrogen, and why the UK's Contract for Difference model offers a potentially powerful template for SAF policy support. From the prospects of HEFA feedstock constraints and eSAF economics, this is a wide-ranging conversation for anyone working at the intersection of clean energy finance and aviation decarbonisation.

Alasdair Lumsden, Carbon Neutral Fuels: Ctrl C, Ctrl V-ing future of eSAF

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.
