Discover how Topsoe’s range of proven technologies is ready to help you meet rising demand and produce Sustainable Aviation Fuel.


Expert perspectives on Sustainable Aviation Fuel

This report provides a comprehensive review of the opportunities and challenges for Sustainable Aviation Fuel (SAF) adoption, featuring leading experts from across the value chain.



The right routes

Ground control, do you copy? At Topsoe we have developed the routes that we think are the best way to reach your destination: low-carbon travel.

From the market-leading HydroFlex™ technology to the single-point license G2L™ Biofuels and eFuels, we have mapped out your optimal routes to achieving feedstock flexibility and ensuring green travel happens now.

Whatever your feedstock, a low-carbon jet fuel with high yields and a high market value is possible.

Technologies tailored to your business


Get full feedstock flexibility with HydroFlex™. This market-leading technology utilizes Topsoe’s hydroprocessing expertise to enable the processing of virgin oils, waste oils and fats, solid biomass, and plastic waste / tires to produce HEFA-based Sustainable Aviation Fuel with minimal Carbon Intensity (CI) compared to traditional petroleum aviation fuel.

HydroFlex™ has a high number of running references, versatile process design, hardware, and a comprehensive range of proprietary catalysts for renewable fuel production.


Go the synthetic- and gas-based route for Sustainable Aviation Fuel with G2L™ Biofuels. This commercially proven technology utilizes Topsoe’s hydroprocessing technologies as well as Sasol’s LTFT™ technology to produce Fischer-Tropsch Synthetic Paraffinic Kerosene (FT-SPK).

We supply the core technologies and engineering, catalysts, proprietary hardware, and technical services in a single-point license and offer a feed-in / product-out guarantee.

G2L™ eFuels

Create eFuels from renewable energy via green hydrogen, and from CO2 via carbon capture. By combining synthesis gas, Fischer-Tropsch and hydroprocessing technologies, the G2L™ eFuels solution efficiently produces FT-SPK/eJet and a green naphtha.

The process is built around already proven solutions, integrating newly developed technologies like our fully electrified eREACTTM. This means a viable way forward for establishing eFuels production is ready now.

The Fischer-Tropsch technology is provided by our strategic partner Sasol under a single-point-license.

MTJet™ Biofuels

A robust SAF pathway that uses methanol as an intermediate in jet fuel production, allowing producers to handle and capitalize on a range of bio feedstocks.

Our MTJet™ technology is based on years of commercial experience and internal research and development within methanol synthesis and methane-rich gas-to-gasoline processes – TIGAS™.

MTJetTM eFuels

Using Topsoe’s methanol synthesis process, MTJetTM eFuels can operate at just 10% of its design capacity and handle temporary electrolyzer shutdown, allowing operations to run directly off methanol storage tanks. The result is a methanol-to-jet solution that can deliver eJet fuel from renewable electricity, water, and CO2 – creating a truly end-to-end feedstock-to-fuel process pathway.

The process grants the flexibility to handle feedstock fluctuations while providing around-the-clock operational stability. 

Knowledge Special: SAF TALKSTM

Sustainable Aviation Fuel (SAF) is recognized as the most important solution currently available to the aviation industry as it looks to drive down its CO2 emissions and lower its impact on the environment. SAF is presently the only sustainable alternative to conventional jet fuel but yet it currently provides just 0.1-0.15% of global jet fuel use.

So what will it take to get SAF use off the ground? In our special Topsoe SAF Talks Series, recorded at the December 2022’s SAF Summit in Copenhagen, we gathered global experts spanning the SAF value chain to share their opinions and latest insights.
