Elyse Energy, a French sustainable aviation fuel developer, has made significant strides in its BioTJet project by selecting biofuel technology powered by clean hydrogen. This innovative approach involves converting wood waste and forestry residues into cleaner jet fuel. The company, in collaboration with project partners, has chosen thyssenkrupp Uhde's BioTfueL® technology for this venture located in the Pyrénées-Atlantiques region of France. The BioTJet project targets the production of 110,000 tonnes of e-fuels beginning in 2029. The technology, which was previously tested in a semi-industrial plant by the Bionext consortium, is expected to provide cost-competitive e-fuels. Axens, one of the partners, signed a license agreement for the BioTfueL® technology in 2024, marking a significant advancement. Once operational, BioTJet is poised to become France's inaugural commercial e-biofuel plant, with the capacity to generate 75,000 tonnes of sustainable aviation fuel and 35,000 tonnes of naphtha for various sectors. Basic engineering for the project was finalized in November 2024, moving it into the detailed engineering phase. The European Union's focus on sustainable aviation fuel is evident through the ReFuelEU Aviation regulation, which mandates a gradual increase in the use of SAF. By 2025, the regulation requires SAF to constitute 2% of European aviation fuel supplies, with a target of 70% by 2050. Although SAF is recognized as a key solution to reducing aviation emissions, challenges such as high production costs and feedstock limitations have hindered widespread commercial production.
