In this episode of The SAF Podcast, we are joined by Jim Stonecipher, Managing Director at EdyMac and former executive at Fulcrum BioEnergy.

With over 30 years of chemical engineering experience, Jim offers a candid, behind-the-scenes look at Fulcrum's high-profile journey—from promise to Chapter 11 bankruptcy. The company's ambitious vision to convert municipal solid waste into sustainable aviation fuel represented a promising technological pathway, but faced numerous obstacles—from COVID-related supply chain disruptions to fundamental issues with technology scale-up and integration.

The conversation explores the delicate balance between technological development and financial reality, revealing how the notorious "valley of death" between pilot demonstration and commercial deployment claims so many promising innovations. Stonecipher advocates for more thorough engineering work early in the development process, describing it as "intelligence gathering" that identifies risks before they become expensive problems.

At the heart of Stonecipher's message is some crucial advice for technology developers: pilot testing must be comprehensive, integrated, and representative of what will be deployed at commercial scale. "The more you can mimic at the pilot scale," he explains, "the higher your chances of success." This lesson, while seemingly straightforward, runs counter to the pressure many startups face to move quickly toward commercialization to satisfy investor timelines.

The conversation also delves into investor relations, capital stack composition, and how early-stage decisions can make or break long-term success. Jim explains that he sees promise in more modular, incremental approaches to scaling SAF production—starting smaller, proving performance, and then replicating successful units rather than attempting massive facilities from the outset. This "Lego-style" approach could help bridge the gap between technological promise and commercial reality.

This week on the SAF Podcast Smitha Hariharan, Vice President and Chief Sustainability Officer at Gulfstream Aerospace, discusses how one of the leading business jet manufacturer is pioneering sustainability through a comprehensive three-pillar strategy that balances environmental responsibility with business performance, with a heavy focus on Sustainable Aviation Fuel since 2011.

From Gulfstream's groundbreaking 2011 transatlantic flight using 50% SAF to their 2023 achievement of flying a G600 from Savannah to Farnborough with 100% SAF in both engines (a full week before Virgin Atlantic's much-publicized commercial demonstration).

Hariharan reveals Gulfstream's comprehensive sustainability strategy built on three pillars: aircraft efficiency, operational improvements, and fuel innovation. The company has committed to reducing Scope 1 and 2 emissions by 40% by 2034 while supporting the aviation industry's ambitious 2050 net-zero goal. Their groundbreaking achievements include the first transatlantic business jet flight using 100% SAF—accomplished one week before Virgin's celebrated commercial flight.

The conversation explores how corporate customers are increasingly demanding sustainable aviation solutions, driving business aviation's transformation. Hariharan discusses the critical importance of book-and-claim mechanisms for expanding SAF access, particularly at smaller regional airports where business jets operate. She also addresses the challenges of scaling beyond HEFA-based SAF to next-generation pathways essential for meeting 2050 targets.

As a member of the Business Aviation Coalition for Sustainable Aviation Fuel, Gulfstream continues advancing industry-wide SAF adoption through rigorous testing, ASTM evaluation processes, and strategic partnerships with engine manufacturers like Rolls-Royce. This episode provides invaluable insights into how business aviation serves as a crucial testing ground for sustainable aviation innovations that will eventually benefit the entire aviation sector.

This week Andre de Fontaine, Sustainable Aviation Buyers Alliance (SABA) joins us on The SAF Podcast. Founded in 2021, SABA has been at the forefront of driving the Book and Claim conversation and allowing corporates to purchase SAF for their operations when they cannot control what fuel they fly on.

Andre explains how SABA has grown to include approximately 35 major companies—including BCG, Bank of America, Netflix, and Meta—that share ambitious climate targets and significant aviation footprints. Together, they've facilitated around $200 million worth of SAF certificates representing 50 million gallons of sustainable fuel. The evolution has been dramatic; what began as an almost non-existent market in 2021 now features multiple producers and growing corporate demand.

We also discuss one of SABA's latest initiatives, the launch of SAF Connect, a platform designed to streamline the connection between SAF providers and buyers. Lowering the barriers to entry and the ease with which companies can access SAF is critical to accelerating the higher levels of demand.

The conversation also looks at whether SAF certificates have the ability to provide the long time certainty required by investors to consider demand signals bankable and make projects worth investing in, how purchasing certificates directly from producers or in partnership with airlines differ.

In this episode of The SAF Podcast, we welcome Gediminas Ziemelis, Founder and Chairman of Avia Solutions Group, to discuss the company’s move into sustainable aviation fuel (SAF) production through its NorSAF project. As the world’s largest wet-leasing provider, Avia Solutions Group operates across six continents and is now leveraging its extensive infrastructure to help decarbonize aviation.

Gediminas shares how the company is developing a state-of-the-art SAF and eSAF production facility in Liepāja, Latvia, strategically positioned to serve the Baltic, Nordic, and Central European regions. He reveals how acquiring an existing oil storage terminal has saved years on permitting and construction, while enabling cost-effective scaling of synthetic SAF production using KBR’s PureSAF technology—based on captured CO₂ and green hydrogen.

Behind this ambitious venture lies a revealing look at how nimble, privately-held companies can move faster in the green transition. Unlike publicly-listed giants retreating from environmental initiatives to focus on core business, Avia Solutions Group can make rapid decisions without justifying every move to shareholders. This agility might be exactly what's needed to accelerate aviation's sustainability journey.

Beyond environmental benefits, Ziemelis frames the project as a strategic move toward European energy independence—drawing parallels to how Europe developed sugar beet production in the 18th century to reduce dependency on imported sugar cane. Could synthetic aviation fuel represent the next chapter in Europe's quest for energy sovereignty? Listen now to discover how the future of flight might be taking shape in the Baltic region.

Check out our previous discussion with Dani Charles, Veriflux on AI and traceability here: https://www.buzzsprout.com/2202964/episodes/17201492

In this episode of The SAF Podcast, we welcome back our first returning guest, Dani Charles, CEO and Co-Founder of Veriflux. Following his deep dive into U.S. policy in his first appearance, Dani returns to unpack the increasingly critical—and complex—world of feedstock traceability in sustainable aviation fuel (SAF) production and how AI can could be the secret to doing it accurately at scale.

Dani explains why relying on spreadsheets are no longer viable at scale and how best-of-breed technology is essential for managing dynamic trade flows, compliance uncertainty, and complex conversions across liquid, solid, and gaseous feedstocks. Does anyone actually know how many bushels make up a bale and how many bales to a ton?

AI offers practical solutions that address real industry pain points. Rather than futuristic robots making decisions, think of it as a "co-pilot for compliance" that can extract information from bills of lading in seconds rather than hours, reconcile data across systems, and ultimately compress days of manual work into automated processes that happen seamlessly in the background. For an industry drowning in paperwork and cross-border regulations, this technological evolution couldn't come at a better time.

We also explore recent developments in U.S. policy, where proposed extensions to the 45Z tax credit could provide regulatory certainty through 2031 while potentially reshaping feedstock preferences toward crop-based materials.

SAF Investor London 2025 is running on the 28th-29th May and is filled with key industry players discussing the critical challenges around scaling SAF investment globally. If this is of interest find out more here: https://www.safinvestor.com/event/145508/saf-investor-london-2025/

You can also listen to our previous episode with Kwame Bekoe, AfriSAF where we discuss growing investment in SAF production and feedstock procurement across Africa here: https://www.buzzsprout.com/2202964/episodes/17070781-the-saf-podcast-afrisaf-tapping-into-saf-s-continental-sleeping-giant.mp3?download=true

This week we are joined on The SAF Podcast by Kwame Bekoe, AfriSAF. With over 20 years of aviation experience spanning engineering, sales, and sustainability, Kwame shares his vision for Africa as a major player in the global SAF industry. He discusses how the continent’s vast agricultural residue—estimated at over 150 million tons annually—can be leveraged to produce SAF, fostering energy independence and economic growth.

We examine AfriSAF’s model of integrating smallholder farmers into a data-driven supply chain, using digital platforms and pilot biodigester projects to prove the value of waste-to-energy conversion. Kwame outlines how AfriSAF is targeting scalable SAF production in countries like Ghana, Kenya, Rwanda, Ethiopia and many others.

What makes this particularly compelling is how it addresses multiple challenges simultaneously. For African nations struggling with energy security, SAF production offers domestic fuel sources at potentially competitive prices – Kwame suggests Africa could be one of the few places where SAF might achieve cost parity with conventional jet fuel. For rural communities facing limited economic opportunities, these projects create meaningful employment that keeps people connected to their agricultural roots while participating in the green economy. And for a continent with the world's youngest population (averaging just 19 years old) that's projected to reach 2.5 billion people by 2050, developing sustainable industries now creates the foundation for long-term prosperity.

The challenges are substantial – from infrastructure limitations to investor risk perception – but the momentum is building. With the African Continental Free Trade Area creating the world's largest open market and continental initiatives promoting easier movement across borders, the conditions for a thriving pan-African SAF industry are emerging. Through strategic partnerships with governments, airlines, and financial institutions, Africa need not just be a consumer of sustainable aviation fuel but could eventually become a significant global producer and exporter.

In this episode of The SAF Podcast, we go behind the curtain of UK sustainable aviation fuel (SAF) policy with former Aviation Minister and former Member of Parliament for the UK Robert Courts.

Listeners will gain a rare glimpse into the complexities of government policymaking—from managing cross-departmental collaboration and limited civil service bandwidth to ensuring stakeholder engagement and long-term adaptability.

Courts candidly addresses industry concerns about implementation timelines, revealing the unavoidable bandwidth limitations within government and the necessity of thorough consultation. He takes us through the formation of the Jet Zero Council (now Task Force), explaining how it transformed the government-industry relationship from policy being "done to" industry to being developed "with" industry. We also discuss the Green Fuels Green Skies competition which paved the way for the Advanced Fuel Fund which has given grants to numerous leading SAF production technology developers in the UK.

This collaborative approach has survived changes in government precisely because sustainable aviation enjoys broad cross-party support.

You can also find out about the process of developing policy, exemplified by the development of the Revenue Certainty Mechanism. We look at the pros and cons of this long process and actually discuss why these processes are in place.

We finish by looking at the big challenges in developing the infrastructure for domestic SAF production as well as what policy makers wish industry understood more about the policy making process.

Make sure you check this episode out to get behind the process of policy development and why policy takes the shape it does.

In this episode of The SAF Podcast, Oscar sits down with Michelle Carter, Head of Transport at Innovate UK Business Connect, to explore the current state and future trajectory of sustainable aviation fuel (SAF) in the UK. With over a decade of experience in SAF, Michelle offers a unique lens into the evolution of the UK’s SAF ecosystem—from early-stage innovation to national mandates and public awareness.

The conversation delves into the UK's position in the global SAF market, revealing that the country attracts just over 1% of global SAF investment, with a surprising 29% focused on power-to-liquid technology. Even more revealing is that domestic investment remains strikingly low compared to foreign capital pouring in from Europe and the United States. Michelle discusses the critical role of the UK SAF Clearing House in helping innovative technologies navigate regulatory landscapes and the importance of domestic versus imported production.

The episode highlights interesting contrasts between UK and international investment patterns, particularly examining Spain's success with operational SAF facilities. Michelle explains how government policies like the SAF mandate and renewable certainty mechanism aim to stimulate growth in domestic production, targeting 2% sustainable jet fuel by 2025 and 10% by 2030.

The conversation also covers international comparisons, such as Spain’s refinery-led approach, and why the UK still imports most of its SAF. We delve into public perception, noting that 70% of UK adults still don’t know what SAF is—highlighting the critical role of airlines, airports, and producers in improving consumer education.

The regional variations in understanding—particularly how Wales demonstrated superior knowledge about waste-gas pathways due to local industry initiatives—highlight both the challenges and opportunities in consumer education. As Michelle notes, "If you communicate with the right narrative, people get it and they understand it."

Whether you are a UK local or from another geography, understanding the challenges and work being done in the UK, and across the globe is critical to decarbonise aviation globally.
