Mandate Met, But the Hard Targets Lie Ahead

Clearing a 2% SAF blend is a compliance milestone, not a commercial breakthrough. The ReFuelEU Aviation regulation ratchets steeply: the synthetic PtL sub-mandate — the fraction that must come from RFNBO-derived e-fuels rather than HEFA or other bio-pathways — rises to 1.2% by 2030 and 35% by 2050. The 1.1 million tonnes recorded in 2025 was overwhelmingly bio-based; the PtL component remains negligible at commercial scale. The regulation’s certification machinery, which requires fuel suppliers to demonstrate RED III-compliant renewable electricity inputs under the RFNBO rules, will bear hard on any producer claiming the PtL sub-mandate credit.

Compliance teams are already deploying AI-assisted platforms that cross-reference RED III additionality and temporal-correlation requirements against production logs and grid certificates, automating the audit trail that national competent authorities will scrutinise. The complexity of that certification stack is one reason the Early Movers’ Coalition matters: guaranteed offtake underwritten at the government level reduces the financing risk that makes PtL plant FIDs so difficult to reach.

Coalition Logic: Why Demand-Side Policy Unlocks Supply

Austria and France’s accession to the Early Movers’ Coalition brings the bloc to eight member states willing to commit public procurement or contract-for-difference mechanisms to synthetic aviation fuel. The coalition’s logic is straightforward: PtL e-kerosene currently costs three to five times more than fossil jet fuel, and no airline will voluntarily absorb that premium at scale without a floor price or blending obligation backed by sovereign guarantees. By pooling demand across borders, the coalition creates the volume signal electrolyser and e-fuel plant developers need to reach bankable capacity thresholds. Germany’s separately announced €2 billion scheme to reduce synthetic SAF costs sits in the same policy frame — a recognition that supply will not materialise through the mandate alone.

It is worth stating the main engineering objection plainly: PtL e-fuels carry a well-to-wheel efficiency of around 16% against roughly 72% for a battery-electric vehicle, a gap the ICCT describes as over four times more efficient in favour of the BEV. For road cars and light vans that objection is decisive. For long-haul aviation, where energy density and drop-in compatibility with existing fleets are non-negotiable, there is no battery alternative on the horizon — which is precisely why ReFuelEU targets this sector and not the passenger car fleet.

Certification Pipeline and What Comes Next

For compliance officers, the immediate pressure point is documentation. Fuel suppliers obligated under ReFuelEU must demonstrate, batch by batch, that blended volumes meet the origin and sustainability criteria of RED III, including the RFNBO electricity sourcing rules where the PtL sub-mandate applies. EASA’s confirmatory role in the EU’s SAF certification architecture adds a further verification layer. The Early Movers’ Coalition’s offtake structures will need to be designed so that contracted volumes are traceable through the mass-balance system — a non-trivial task when e-kerosene is produced at one location, blended at another, and lifted at a third.

The policy momentum is real, but the gap between a met 2% target and a credible pathway to the 2030 PtL sub-mandate is large. Project developers, certification bodies, and the member states now financing demand-side support will need the next 18 months to translate coalition commitments into signed offtake agreements and shovel-ready electrolyser capacity.
