Saipem to Engineer Synhelion’s 30,000-Ton Synthetic Fuel Plant in Germany

Saipem has secured an engineering services contract from Swiss renewable synthetic fuel producer Synhelion AG to advance the development of a commercial-scale synthetic fuel facility in Germany. The agreement covers pre-Front-End Engineering Design (pre-FEED) activities for the proposed plant, which will be established at RWE’s Chemiepark Knapsack industrial site in Hürth, Germany.

The planned facility is expected to have an annual production capacity of approximately 30,000 tonnes of RED-compliant renewable synthetic fuels. Sustainable Aviation Fuel (SAF) will represent the primary product, while the plant will also manufacture synthetic diesel and gasoline. These renewable fuels are intended to serve multiple transportation segments, including aviation, maritime shipping, and road mobility.

Under the contract, Saipem will prepare a comprehensive multidisciplinary pre-FEED engineering package. The work will focus on defining the plant’s overall configuration and integrating Synhelion’s proprietary synthetic fuel technology with fuel synthesis and upgrading processes. The engineering design will also incorporate the infrastructure available at RWE’s Chemiepark Knapsack site.

The pre-FEED phase represents an important step in the project’s development because it will establish the technical framework needed for subsequent stages. Saipem’s engineering package is expected to support the regulatory permitting process and provide the foundation for the future FEED phase. The work will ultimately contribute to preparations for the project’s Final Investment Decision (FID).

The collaboration strengthens Saipem’s position in the sustainable fuels sector, particularly in projects that require the integration of advanced technologies with large-scale industrial infrastructure. For Synhelion, the partnership provides engineering expertise to help translate its proprietary technology into a commercial-scale production facility.

The project also highlights the growing European focus on renewable fuels as the transportation sector seeks alternatives to conventional fossil-based fuels. SAF, in particular, is gaining importance as airlines and fuel producers face increasing pressure to reduce lifecycle carbon emissions and comply with tightening environmental regulations.

If successfully developed and commissioned, the facility could contribute to the expansion of Europe’s renewable synthetic fuel production capacity. It may also demonstrate the scalability of Synhelion’s technology while creating an additional source of low-carbon fuels for hard-to-abate transportation applications.

Overall, Saipem’s pre-FEED contract marks a significant development in the project pipeline and establishes an engineering pathway toward commercial-scale production of renewable synthetic fuels in Germany.

Product and Chemical Commodity Price Impact

The announcement is bullish for SAF and renewable synthetic fuel demand, as the proposed 30,000-tonne/year plant strengthens Europe’s emerging e-fuels capacity. However, the immediate impact on conventional chemical commodity prices should remain limited because the project is still at the pre-FEED stage and commercial production is several years away. In the longer term, higher SAF output could gradually reduce demand growth for conventional jet fuel, while renewable diesel and gasoline could compete with fossil-derived alternatives. Demand for hydrogen, carbon dioxide, catalysts, specialty chemicals, and renewable feedstocks may increase as synthetic fuel capacity expands, potentially supporting prices for these related commodities.
