Axens has launched plans for France’s first industrial-scale sustainable aviation fuel plant based on advanced bioethanol, targeting annual production of 50,000 tonnes from 2030.
Named ERA, for Ethanol to Refuel Aviation, the project is currently progressing through engineering and site selection. A dedicated company called SAFIRIS will deliver the development, with Axens assembling industrial and financial partners before a final investment decision.
The plant will use Jetanol technology developed by Axens and IFP Energies nouvelles. Bioethanol is converted into sustainable aviation fuel and bio-naphtha through three main process stages: dehydration, oligomerisation, and hydrogenation.
Dehydration removes water from ethanol to produce ethylene, after which oligomerisation joins smaller molecules into longer hydrocarbon chains. Hydrogenation then saturates and upgrades the resulting material into products suitable for further finishing and aviation-fuel blending.
Axens intends to source advanced ethanol from European feedstocks, including biomass residues rather than conventional food crops. That approach broadens the raw material base beyond the oils, used cooking oil, and animal fats used by the dominant hydroprocessed esters and fatty acids route.
Availability of suitable waste oils is limited, particularly as renewable diesel and other fuel producers compete for the same material. Alcohol-to-jet offers an alternative pathway that can use established ethanol production, storage, and logistics while drawing on agricultural and forestry residues.
The proposed output is significant enough to demonstrate continuous industrial operation, although it remains modest beside conventional refinery volumes and projected aviation demand. Axens estimates that flights departing France will require more than one million tonnes of sustainable aviation fuel annually by 2035.
ReFuelEU Aviation obliges fuel suppliers to increase the sustainable share delivered at European airports, reaching 6% in 2030 and rising substantially thereafter. Meeting those targets will require several production routes because no single feedstock can provide the necessary volume.
Used oils, advanced ethanol, lignocellulosic biomass, renewable hydrogen, captured carbon dioxide, and potentially methanol will each support different projects according to regional resources, technology maturity, energy prices, and available infrastructure.
Site selection will determine much of ERA’s operating cost. Access to ethanol, hydrogen, electricity, steam, water, storage, transport, skilled labour, and finished-fuel distribution must be considered alongside land availability and permitting.
A location near existing chemical or refining infrastructure can reduce capital spending by sharing utilities, laboratories, storage, loading facilities, and safety systems. It can also complicate integration if existing assets cannot provide sufficient low-carbon energy or if competing plants require the same services.
Hydrogen is central to the final conversion stage. The plant’s carbon performance will improve when low-emission hydrogen is available, but European supplies remain limited and expensive compared with hydrogen produced from natural gas without carbon capture.
The lifecycle emissions of the finished fuel depend on more than the processing unit. Feedstock origin, fertiliser, land use, collection, transport, ethanol production, electricity, hydrogen, conversion efficiency, and by-product treatment all contribute to the carbon value used for regulatory compliance.
Traceability must therefore follow the material from residue or biomass source to airport delivery. Certification systems will need reliable mass balances and evidence that the ethanol meets sustainability criteria before the finished fuel can qualify towards mandated volumes.
Feedstock contracts present another industrial challenge. Agricultural and forestry residues vary by season, region, moisture, contamination, and competing use. Ethanol producers require sufficient continuity to operate efficiently, while excessive concentration around one material can expose the chain to poor harvests or price changes.
Axens is positioning ERA alongside its NACRE advanced bioethanol development at Lacq and its MACARON battery materials project in Valenciennes. The combination links process technology, plant engineering, feedstock conversion, and industrial production within a wider French reindustrialisation programme.
The project could also provide a reference plant for Jetanol licensing. Process technology companies depend on operating data from industrial units to demonstrate yield, reliability, catalyst life, energy consumption, maintenance requirements, and product quality to later customers.
A successful 50,000-tonne facility could therefore support larger or replicated plants elsewhere. Replication will still require local engineering because feedstock quality, utilities, regulations, logistics, and product markets differ between sites.
Before construction can begin, SAFIRIS must complete engineering, select a site, secure permits, confirm financing, contract feedstocks and energy, and establish reliable routes to market. Long-term purchase agreements with airlines or fuel suppliers may be necessary to support debt and protect the project against volatile fossil jet prices.
ERA will test whether alcohol-to-jet technology can progress from demonstration and licensing studies into a repeatable European manufacturing model. Its planned 2030 start aligns with a major increase in mandated SAF demand, leaving a limited margin for delays across permitting, finance, equipment supply, construction, and commissioning.
