Topsoe and Sasol have been selected to supply technology for a major synthetic sustainable aviation fuel (e-SAF) project in Sweden, paving the way for a planned plant with an annual production capacity of approximately 66,000 metric tons.
The two companies have signed a license and engineering agreement with Alby PtX for the proposed facility in Alby, Sweden, which is expected to take a final investment decision in 2028 and begin operations in 2031.
The project will deploy an integrated gas-to-liquid (G2L) technology package combining Topsoe’s eREACT and hydroprocessing technologies with Sasol’s low-temperature Fischer-Tropsch (LTFT) technology.
The integrated process will convert renewable hydrogen and captured carbon dioxide into synthetic hydrocarbons, which will subsequently be upgraded into aviation fuel. The planned output is intended for the European Union and UK markets.
Under the agreement, Topsoe will provide the eREACT and hydroprocessing technologies, while Sasol will supply its Fischer-Tropsch technology. Their engineering packages will provide the technical foundation for the project's next development phase and support progress towards a final investment decision.
Yassir Ghiyati, Chief Commercial Officer at Topsoe, said: “Scaling e-SAF production is an important step towards strengthening Europe’s energy resilience, fuel supplies and decarbonizing aviation. Through our strong gas-to-liquid offering, which combines Topsoe’s and Sasol’s advanced technologies, we can support Alby PtX as it advances the project to its next stage of development.”
Sarushen Pillay, Executive Vice President for Business Building, Strategy and Technology at Sasol, said: "We are pleased to bring decades of experience in Fischer-Tropsch technology to this project, working with Topsoe to provide Alby PtX with an integrated technology solution for the production of sustainable aviation fuel.
"Through the partnership, Sasol and Topsoe are licensing the technology and providing the licensor package, technical expertise and capabilities to support the development of the facility, which will convert renewable hydrogen and captured carbon into sustainable aviation fuel. Alby PtX is a strong example of how proven technology and collaboration can help advance sustainable aviation fuel projects towards commercial reality and support the development of lower-carbon aviation at scale.”
Andreas Schmid, Chairman of the Board at Alby PtX and Executive Director at Prime Capital AG, said: "Topsoe and Sasol bring an established technology partnership and extensive experience in certified synthetic fuel production. For Alby PtX, this means putting technology proven over decades to work in a new application.
"The strength of this combination lies in how the technologies work together: making efficient use of renewable power and captured carbon while maximizing aviation fuel output. This gives us a strong foundation to advance the project and contribute to both aviation’s decarbonization and a more resilient European fuel supply.”
The selection marks another collaboration between Topsoe and Sasol in the emerging e-fuels sector. The companies have recently entered into joint agreements with HDF Energy, Bharat Petroleum and Allied Biofuels.
