Uniper Signs 10-Year eSAF Offtake Deal with Arcadia eFuels for 40,000 Tonnes Annually
Why It MattersThe deal signals that long-dated offtake contracts, rather than spot purchases, are becoming the mechanism by which utilities and fuel producers de-risk eSAF's jump from pilot projects to industrial-scale EU production.
What happened
German state-owned utility Uniper has signed an agreement to purchase 40,000 metric tonnes of synthetic sustainable aviation fuel (eSAF) annually from US-based Arcadia eFuels for more than 10 years, the companies announced on Wednesday, September 23. The fuel will be supplied from Arcadia eFuels' Endor project in Denmark, with deliveries expected to begin in the early 2030s.
The companies described the deal as one of the largest eSAF offtake agreements to date. They said the volume would cover the fuel equivalent of approximately 1,000 Boeing 787-9 flights per year from Düsseldorf, where Uniper is headquartered, to Abu Dhabi.
Uniper CEO Michael Lewis said, "The key challenge now is to move sustainable aviation fuels from promising projects to industrial scale," adding, "For Uniper, it is also an important step in building a strong position in a market with significant growth potential." Arcadia eFuels CEO Amy Hebert said the agreement brings expanded EU production of eSAF meaningfully closer.
The deal comes as the European Union mandates that 2% of fuel made available at regional airports be SAF by 2025, rising to 6% by 2030, with eSAF required to account for 1.2% of the total from 2030, increasing to 5% by 2035.
Industry impact & what to watch
This agreement belongs to a growing category of multi-year eSAF offtake contracts that fuel producers use to secure the revenue certainty needed to justify building industrial-scale plants years before those plants exist. Because Arcadia eFuels' Endor project will not deliver until the early 2030s, the deal functions as a financing signal as much as a supply commitment, aimed at a buyer that itself has volume obligations under EU blending mandates rising from 2% in 2025 to 6% by 2030.
How this segment works is visible in the mandate structure itself: the EU schedule separates a general SAF share from a distinct, smaller eSAF sub-target — 1.2% from 2030 climbing to 5% by 2035 — which forces buyers like Uniper to lock in synthetic-fuel supply specifically, since conventional SAF volumes cannot substitute for that carve-out.
What remains to be seen is whether the Endor project reaches final investment decision and construction on the timeline needed to meet early-2030s deliveries, and whether other airlines or utilities follow with comparable long-dated eSAF contracts as the 2030 mandate deadline approaches.
