The Medhyterra ammonia import terminal project in Fos-sur-Mer will provide a sustainable alternative for local industries. Tractebel’s Gas-to-X experts and partners conducted the preliminary design studies for the low-carbon ammonia terminal.
Part of the Fos Tonkin liquified natural gas (LNG) terminal, west of Marseille in the south of France, is being repurposed by client Elengy in the name of the energy transition. A former LNG tank will be replaced by a 30,000 m³ ammonia tank. The new terminal aims to import, store and distribute 200 kilotons per year of low carbon ammonia (NH3), with big implications for decarbonization in the region.
Tractebel conducted the preliminary Front-End Engineering Design (pre-FEED) studies of the ammonia terminal, with the support of Tractebel company IMDC for the marine and maritime engineering and Proton Ventures for the ammonia process. The pre-FEED studies began in April 2024 and were completed by the end of that year.
Our mandate included:
The pre-FEED studies facilitated the consolidation of a strong design for the ammonia terminal installations, leveraging expertise, feedback from the operations of existing terminals, and initial discussions with suppliers. By combining their complementary expertise, Tractebel and Proton Ventures enhanced the skills of Elengy staff in ammonia molecule handling, assisted in outlining the cost, planning, and risk management for this strategic project, and established a clear definition of the project's next steps based on robust design principles.
The Fos Tonkin liquified natural gas (LNG) terminal in the south of France, is being repurposed to accommodate a 30,000 m³ ammonia tank.
Once complete, this ammonia import terminal will distribute the low-carbon ammonia by train, truck, and by pipeline to adjacent industrial sites for hydrogen (H2) production. Export by ship (bunkering) is also planned.
Low-carbon ammonia import at Fos-sur-Mer can directly contribute to the decarbonization of industries in the southern region of France and beyond, impacting sectors such as agriculture, chemical, and automotive. When converted into low-carbon hydrogen, it can also significantly aid in reducing emissions in the refining, metallurgy, and heavy mobility sectors. Therefore, the development of this terminal will be a powerful catalyst in supporting the region’s industrial decarbonization and energy transition goals.
“Our team is proud that Elengy has chosen Tractebel for our expertise to support it on the groundbreaking NH3 import project Medhyterra,” says Sébastien Jacquet, Unit Director of Gas-to-X, Tractebel in France. “Together with Elengy, our mission is to contribute to decarbonization through this innovative project. This initiative aligns perfectly with Tractebel's mission and vision of designing a carbon-neutral future.”
