France plans e-SAF double-sided auction in 2027 budget

France plans to buy up to 160,000 t/yr of synthetic aviation fuel through a double-sided auction scheme, with any ultimate shortfall covered by the aviation fuel sector rather than the state, its 2027 budget bill published on 1 October shows.

Under the bill, a state-appointed body would buy e-SAF from producers under contracts of up to 15 years, awarded through a competitive auction. It would then sell the fuel to aviation fuel suppliers in a second auction under shorter contracts, for example of 3-5 years, the government said in an impact assessment. Purchase prices could be linked to power prices.

E-SAF made using renewable or low-carbon electrolytic hydrogen would be eligible, allowing projects powered by nuclear generation to compete.

The scheme is intended to give producers the long-term certainty needed to take final investment decisions, the government said this week. France is the latest member of the EU's eSAF Early Movers Coalition to plan a double-sided auction. Germany, Austria and Luxembourg recently confirmed plans to launch their own.

The appointed body would be barred from having more than 160,000t under contract in any year. This would be enough to meet France's e-SAF requirement under the EU's ReFuelEU Aviation rules until 2034, the assessment said. ReFuelEU requires a 2pc e-SAF share in 2032-34 and 5pc from 2035.

Any shortfall between the body's purchase costs and resale revenue would first be covered by earlier surpluses, followed by revenue from ReFuelEU fines and finally a new charge on fossil jet fuel suppliers.

The government expects the scheme to earn about €200mn ($225mn) in 2030-33, before losing €500mn-1.2bn in 2034-40, depending on prices. It estimates a net cost of about €650mn over 10 years.

This suggests the government expects fuel suppliers initially to pay a premium for scarce e-SAF when the ReFuelEU requirement starts in 2030, as they face fines and must make up any shortfall in later years. Resale prices could subsequently fall below the body's fixed purchase prices as supply grows and the first resale contracts expire.

The government estimates the cost of producing e-SAF at the first plants at €4,000-7,000/t, compared with €600-1,000/t for conventional jet fuel and around €2,000/t for bio-SAF.

The 160,000 t/yr cap is equivalent to the output of two large projects representing nearly €3bn of private investment, industry body France Hydrogene said. France has 12 e-SAF projects that could become operational in 2030-35, with combined production capacity of more than 800,000 t/yr, 3.4GW of electrolysis and over €14bn of potential investment, it said.

The budget bill also confirms €1.2bn ($1.35bn) for the second round of subsidies targeting 250MW of electrolysis capacity. This is equivalent to about €4.8mn/MW, in line with the €778mn recently awarded to 161MW in the first round.

The bill must still pass parliament, while the e-SAF double-sided auction scheme requires European Commission state aid approval before it can start.
