Market-leading technology platforms
Zaffra combines world-class technology with decades of project execution experience to deliver scalable, cost-competitive SAF solutions.
eSAF production, designed and engineered for scale
The proprietary G2L™ eFuels technology from Zaffra’s shareholders transforms clean electricity, water and sustainable sources of carbon dioxide into ASTM-certified sustainable aviation fuel (SAF). The result: a true drop-in solution, fully compatible with existing infrastructure, aircraft and fuel systems.
Built on Sasol’s proven Fischer-Tropsch (FT) technology and Topsoe’s innovative eREACT™ process, our solution sets the benchmark for scalable, future-proof eSAF production. Delivering class-leading efficiency, it maximises SAF yield per unit of power and CO₂ used, achieving the industry’s lowest lifecycle carbon emissions for jet fuel production.

The path to eSAF scale-up
Scaling sustainable aviation fuel production requires more than ambition; it demands balance. The aviation sector must achieve deep carbon reductions while maintaining compatibility with today’s fuel infrastructure and commercial realities.
At Zaffra, we bridge that gap. Our ambition is built on world-leading technologies, proven at scale and ready to accelerate the transition to low-carbon flight. By combining innovation with real-world execution, we’re charting the most practical and impactful path to SAF scale-up – one that delivers both performance and sustainability.
FAQs
01 What technology does Zaffra implement?
Zaffra delivers market-leading Power-to-Liquids (PtL) eSAF solutions through its shareholders’ proprietary G2L™ eFuels platform – the most advanced and efficient PtL technology available today. It combines Sasol’s Fischer-Tropsch (FT) synthesis with Topsoe’s eREACT™-based Reverse Water Gas Shift (RWGS) and Product Work-up technologies.
02 How does Zaffra use its technology?
We turn world-class technology into real-world impact – establishing strategic partnerships that can accelerate the development and scale-up of eSAF production. By combining proven process and operational know-how with deep project execution capabilities, we transform Power-to-Liquids (PtL) technology into commercially viable projects.
03 Why does Zaffra focus on eSAF?
- Electro-sustainable aviation fuel (eSAF) enables deep cuts in lifecycle emissions versus fossil jet fuel – up to 100% lower.
- eSAF has fewer feedstock constraints than bio-based SAF, making it a scalable solution for decarbonising aviation.
- EU and UK eSAF blending mandates will make eSAF essential to meeting global regulatory goals.
04 What makes Zaffra uniquely equipped to lead the eSAF transition?
Zaffra benefits from a strong head start in the race to operationalise eSAF globally through the proven capabilities of its shareholders, Sasol and Topsoe. Together, we bring decades of operational excellence, breakthrough technology platforms and deep project execution expertise gained on some of the world’s most complex energy assets.
