The SAF Podcast

In this episode, Oscar is joined by two guests at the heart of Europe's eSAF scale-up effort: Amy Herbert, Arcadia eFuels, and Thomas Engelmann, KGAL— both key figures within Project SkyPower, the industry coalition to the European Commission to put in place the conditions needed to bring eSAF projects to final investment decision.
Amy opens with an overview of Arcadia eFuels and its flagship Project Endor in Denmark — one of the most advanced eSAF projects in Europe, with FEED complete, permits secured, and an offtake agreement on the verge of being signed. Thomas explains KGAL's role as an infrastructure equity investor — with a stake in Project Endor — giving him a view of the eSAF financing challenge.
The conversation digs into Project SkyPower's ten-point recommendation letter to the European Commission, with a particular focus on the proposed double-sided auction mechanism and the role of H2 Global as a market-making intermediary. We explore why this instrument is seen as critical to breaking the chicken-and-egg deadlock between offtakers and producers — and why the timeline for getting it in place is a source of real concern, given that the 2030 eSAF mandates are fast approaching and greenfield refineries take years to build.
We also have a frank debate on airline competitiveness and the level playing field argument, whether eSAF is being treated fairly given that new fossil refineries would face comparable economics, why renewable electricity cost — not policy complexity — is a fundamental driver of eSAF pricing, and why the question isn't really whether to be optimistic about 2030, but what Plan B looks like if Europe fails to act.

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

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.

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, 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.
