Germany, Austria and Luxembourg have committed up to €2.12 billion in public funding to back the launch of a joint electricity-based Sustainable Aviation Fuel (eSAF) auction mechanism, designed to bridge the price gap between fuel producers and airline buyers.

Germany will provide up to €2 billion, with Austria and Luxembourg each contributing up to €60 million, according to a joint government announcement. The mechanism matches eSAF supply bids with airline demand through competitive bidding, with the gap between the two sides covered by state subsidies.

Why a double-sided auction?

eSAF — also known as power-to-liquid fuel — is produced from renewable hydrogen generated via electrolysis and captured carbon. Industrial-scale production demands heavy upfront capital, but producers need long-term off-take agreements to secure financing, while airlines typically contract aviation fuel over much shorter timeframes.

The auction aims to resolve that structural mismatch. Bids from producers and demand signals from buyers converge in a competitive process; the resulting contracted volumes receive subsidy support, giving both sides the duration and certainty required to commit capital.

The mechanism targets a specific market failure: producers cannot finance plants without multi-year purchase commitments, while airline procurement teams rarely lock in fuel contracts beyond a few years. Public money, deployed through a transparent auction, underwrites the long tail of those agreements.

What share does each country carry?

Germany accounts for roughly 94% of the committed envelope. The three governments confirmed that subsidized eSAF volumes from the program will enter each country's market in proportion to its contributed share. Germany will absorb the largest contracted tonnage; Austria and Luxembourg will receive allocations scaled to their €60 million contributions.

All three are founding members of the eSAF Early Movers' Coalition, which launched in December 2025 to accelerate the European market ramp-up through cooperation and joint financial support.

How does this fit the broader SAF picture?

Sustainable aviation fuel production nearly doubled in 2025, according to a recent report from the International Air Transport Association (IATA). Even so, SAF accounted for just 0.6% of airlines' total fuel consumption last year.

Fuel represents the vast majority of aviation sector emissions. Conventional SAF, typically produced from waste oils and agricultural residues, runs into finite feedstock supply. eSAF sidesteps that constraint by drawing on renewable electricity and captured CO2 — but it remains the most capital-intensive SAF pathway available.

The three-country initiative lands against that backdrop, with each partner committing to align domestic procurement rules with the auction's contracted output.

What milestone comes next?

The program converts a funding pledge into a procurement schedule. Auction design parameters, contract duration and the first delivery tranche will determine whether the €2.12 billion translates into operating eSAF capacity before the end of the decade.

Steffen Bilger, Germany's Federal Minister of Transport, said: "When it comes to eSAF, Europe needs not only ambitious targets but also investment in industrial production. Germany, Austria and Luxembourg are jointly demonstrating how European cooperation works in practice. We are pooling our funding to create better conditions for investment decisions in a technology of the future."
