H2V Marseille - FOS Project
Renewable hydrogen mass production plant at the Port of Marseille Fos
Since 2016, H2V has been taking up the challenge of producing renewable hydrogen on a mass scale.
H2V is investing in, developing and constructing large-scale renewable hydrogen production plants to decarbonise particularly carbon-intensive sectors, such as industry and heavy-duty mobility.
The H2V FOS project will be sited at the port and carried out in partnership with the Port of Marseille Fos. This site boasts a strategic location that combines strong industrial potential with major seaport activity.
- Six 100MW production units (= 600MW)
- 84,000 T a year of renewable hydrogen
- By water electrolysis
- To be commissioned from 2026
- Creation of about 165 direct jobs and 100 indirect jobs.
- Investment of €700 – €750 million

H2V FOS: an unprecedented partnership for a large-scale renewable hydrogen production project
The site boasts a strategic location that combines strong industrial potential with major seaport activity.
The 36-hectare site is part of the Bassin Sud project led by CSF NSE (the strategy committee for the new energy systems sector), and is a real logistics hub, with the project standing at the crossroads of Trans-European Transport Networks for goods traffic (TEN-T Corridors).
Due to be commissioned from 2026 and then in phases through to 2031, this represents a €750 million investment, the aim of which is to avoid the annual discharge of 750,000 tonnes of CO2 into the atmosphere.
The project is part of the creation of a local hydrogen industry, supported by a regional agreement, combining production, distribution and usage.
