The facility will have a total electrolyser capacity of 40MW to produce 5 tonnes of green hydrogen per day.

Energy companies Total and ENGIE have partnered to design, build and operate the largest green hydrogen production facility in France.
The Masshylia project will be built in Châteauneuf-les-Martigues in the Provence-Alpes-Côte d'Azur South region. The site will be built at Total's La Mède biorefinery facility and will be powered by a 100MW solar PV plant.
The facility will have a total electrolyser capacity of 40MW to produce 5 tonnes of green hydrogen per day. The green hydrogen will be used to power Total's La Mède biorefinery, avoiding 15,000 tonnes of CO2 emissions per year.
Five innovative technologies will be integrated with the project, namely:
- A digital piloting system for the continuous supply of hydrogen with real-time management of solar electricity production
- Optimising the integration of several photovoltaic farms supplying the electrolyser to minimise energy losses and limit grid congestion
- Large-scale hydrogen storage to balance intermittent electricity production and continuous hydrogen consumption
- A direct current connection between a photovoltaic farm and the electrolyser to improve the energy balance
- Enhanced industrial safety thanks to the use of 3D digital models for each component of the installation
