Topsoe, Sasol technologies selected for eSAF project in Sweden

Topsoe, a leading global provider of advanced energy-transition solutions for producing clean and conventional fuels and chemicals, announced Nov. 12 that it and Sasol, a global chemicals and energy company, have signed a license and engineering agreement with Alby PtX for its planned electro sustainable aviation fuel (eSAF) facility in Alby, Sweden.

Under the agreement, Topsoe and Sasol will provide its integrated gas-to-liquid technology, G2L™, combining Topsoe’s innovative eREACT™ and hydroprocessing technologies with Sasol’s low-temperature Fischer-Tropsch (LTFT™) technology.

The G2L™ eFuels process is an end-to-end single-point licensing solution enabling the conversion of renewable feedstocks like gasified biomass or captured CO2 and hydrogen to eFuels.

The agreement follows Topsoe’s and Sasol’s recent joint agreements with HDF Energy, Bharat Petroleum and Allied Biofuels.

“Scaling eSAF production is an important step towards strengthening Europe’s energy resilience, fuel supplies and decarbonizing aviation,” said Yassir Ghiyati, Topsoe’s chief commercial officer. “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, an executive with Sasol, added, “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 SAF projects towards commercial reality and support the development of lower-carbon aviation at scale.”

Andreas Schmid, chairman of 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.”

While the eREACT™ technology will enable synthetic gas production, the hydroprocessing technology will, together with LTFT™, upgrade the synthetic hydrocarbons into aviation fuel and support production of approximately 66,000 metric tons of eSAF annually.

The eSAF is intended for the EU and U.K. markets.

Topsoe and Sasol’s engineering packages will provide the technical basis for the next phase of development, supporting progress towards a final-investment decision (FID).

The project is expected to take FID in 2028 and start operations in 2031.
