The Port of Marseille Fos and H4 Marseille Fos have signed the occupation titles that secure land for a major industrial complex in Fos-sur-Mer, marking a concrete step toward decarbonising one of southern France’s heaviest industrial zones. The agreement, concluded on Tuesday, February 10, anchors the project on the Central Môle and formalises the installation of a site dedicated to low-carbon hydrogen and synthetic fuels, including renewable and low-carbon e-kerosene for aviation.

Led by H4 Marseille Fos, a joint venture combining H2V and Hy2gen, the scheme represents an estimated €1.5bn [$1.62bn] investment and is expected to create 165 direct jobs. The footprint now confirmed covers around 46.6 hectares. The development plan centres on three renewable hydrogen production units with a combined electrical capacity of 300MW, feeding a synthetic fuels unit designed to turn molecules into drop-in aviation fuel. Each hydrogen line is slated to deliver roughly 42,000 tonnes of renewable and low-carbon hydrogen per year, while the downstream plant targets up to 75,000 tonnes of e-kerosene.
