ENGIE x Masshylia - France


How can an industrial site reduce its carbon footprint and become a role model using renewable hydrogen?

By ENGIE - 01 March 2021 - 16:28

To reduce the carbon footprint of its La Mède biorefinery, Total is partnering with ENGIE. Together, they are launching the Masshylia project, intended to become the first French site for the production of renewable hydrogen on an industrial scale. 

The ENGIE solution: using renewable hydrogen on an industrial scale to continuously produce biofuels.


From 2024, Masshylia will produce its first green hydrogen. A first important step towards meeting France's low-carbon energy mix ambitions. 
What is this new solution? Installed in the heart of Total's biorefinery at La Mède in the southern Provence-Alpes-Côte d'Azur region in the south of France, a 40 MW electrolyser, supplied with electricity by solar farms with an overall capacity of more than 100 MW, will produce an average of 5 tonnes of green hydrogen every day to meet the plant's biofuel needs.

How is this project innovative? The project is ground-breaking in a number of ways: thanks to large-scale storage and the implementation of a management system, it will be able to overcome the issue of intermittent solar electricity production. This will guarantee a continuous supply of hydrogen to the biorefinery. The project also includes several photovoltaic farms that will optimise the power supply to the electrolyser.
These innovations make Masshylia a role model for industrial decarbonisation that is unique in Europe.  


An internationally reproducible hydrogen ecosystem

Together with its partner Total, ENGIE plans to have the plant up and running in 2024.
In addition to the biorefinery's own energy needs, the hydrogen produced will be able to serve the needs of the industries surrounding Fos-sur-Mer (Marseille) and local transport and service projects (road, sea and rail).  
Masshylia thus paves the way for a reproducible hydrogen ecosystem, on an industrial and multi-purpose scale, that will contribute to the development of the area while also having an international reach thanks to its proximity to the Mediterranean.


“By working together, ENGIE and Total - two major French energy companies - will facilitate the development of the hydrogen sector and become its leaders thanks to this joint, industrial and internationally reproducible project.” 
Philippe Sauquet, President Gas, Renewables & Power at Total




Key figures

  • An average of 5 tonnes of green hydrogen produced every day by a 40 MW electrolyser.
  • > 100 MWc of total capacity for the solar farms supplying power to the site
  • 15,000 tonnes of CO2 emissions avoided per year, i.e. the annual CO2 consumption of 1,875 people in France.


End of 2024: planned commissioning of the site.
