• Why Zaffra is betting big on sustainable aviation fuel production

  In this episode, we speak with Jan Toschka, CEO of Zaffra, a joint venture between Topsoe and Sasol.  Toschka shares insights about scaling sustainable aviation fuel (SAF) production and why he believes the aviation industry must take responsibility for its own decarbonisation rather than relying on other sectors.Toschka discusses:The unique positioning of Zaffra, combining Topsoe’s expertise in low-carbon HEFA technology with Sasol’s experience in building and operating large-scale gas-to-liquid facilities, positioning them strongly in both renewable and synthetic SAF production.His perspective on financing SAF infrastructure, breaking down the seemingly daunting €250 billion European investment needed by 2050 into more manageable numbers – about €10 billion annually, which could be funded by approximately €10 per passenger across Europe's billion annual travellers.The complementary role of different SAF technologies, with HEFA being the most de-risked pathway currently available, whilst power-to-liquid (PTL) solutions are expected to provide at least 50% of SAF volume in 20-30 years.The importance of both mandates and incentives in driving SAF adoption, with EU mandates helping de-risk demand whilst US incentives under the IRA make investments more manageable. Toschka suggests a combination of both approaches, similar to the UK model, might work best.The strategic approach to SAF distribution, advocating for focused deployment at 20-30 major hub airports initially, supported by book-and-claim systems, rather than attempting immediate widespread distribution across all airports.Toschka emphasises that whilst the aviation industry should pursue multiple decarbonisation pathways including hydrogen and electric aircraft, SAF remains the only viable solution for long-haul aviation in the foreseeable future, and the industry cannot afford to wait for perfect solutions whilst existing aircraft continue operating.If you LOVED this episode, you’ll also love the conversation we had with Sarah Ellerby, CEO of Nova Pangaea Technologies (NPT), a UK-based cleantech company that has created a patented technology to enable SAF production from agricultural and forestry waste.

• Why Mission Possible Partnership believes cross-sector collaboration can accelerate aviation’s path to net-zero

  In this episode, we speak with Dick Benschop, Chair of the Board at Mission Possible Partnership (MPP), an alliance of climate leaders focused on supercharging efforts to decarbonise hard-to-abate sectors.Benschop discusses:The challenge of decarbonising aviation amid rapid growth with focus on both efficiency and sustainable fuels.How blending mandates can break the “chicken and egg” problem between SAF suppliers and airlines, with Europe’s 2% mandate in 2025 serving as a catalyst for market development. Currently, there are 40 SAF plants in operation and 10 with Final Investment Decision (FID), representing about 50% of 2030 capacity needs, with 143 more plants announced*.The importance of smart environmental constraints over simple capacity caps, advocating for declining noise and CO2 emission limits that allow airlines to “earn their place” through innovation.The potential for electric and hydrogen aircraft to serve up to one-third of aviation energy demand by 2050, with electric planes operational by 2030 and hydrogen aircraft following by 2035.How breaking down silos between sectors can accelerate decarbonisation, using lessons from aviation’s blending mandates to inform solutions in other industries like green fertiliser production.Benschop emphasises that achieving net-zero aviation requires looking beyond individual sectors to system-wide solutions, highlighting the need for coordinated action across industry, government and consumers. *Note: The podcast mentions different figures for the number of SAF plants needed. The numbers cited above reflect MPP’s latest analysis, which shows that actual plants are larger than initially assumed, meaning fewer total plants are needed to meet 2030 capacity targets. If you LOVED this episode, you’ll also love the conversation we had with Andrew Chen, Principal for Aviation Decarbonisation at RMI, who shares the non-profit’s multi-faceted approach to aviation decarbonisation.
