Sustainability In The Air 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.
