How to produce, store and distribute green hydrogen on an industrial scale ?

By ENGIE - 16 December 2019 - 19:02

ENGIE, the Durance, Luberon, Verdon (DLVA) and Air Liquide conurbation have decided to join forces to develop the "HyGreen Provence" project, which aims to produce, store and distribute green hydrogen. This project is expected to produce 1300 GWh of solar electricity, equivalent to the residential consumption of about 450,000 people for one year, as well as hydrogen water electrolysis on an industrial scale. In the long term, several tens of thousands of tonnes of renewable hydrogen per year could thus be produced to meet a very wide range of requirements. The signing of this innovative public-private partnership was made possible thanks to the involvement of the many stakeholders committed to the zero-carbon transition and will fully contribute to the development of the hydrogen sector in France.


Key figures


  • 1300 GWh of solar electricity produced, equivalent to the residential consumption of approximately 450,000 people for one year
  • Project phases: first achievements at the end of 2021; final phase planned for 2027
  • Ultimately, thousands of tonnes of renewable hydrogen will be produced per year for a wide range of uses.


Client Challenges


  • Deploy green mobility stations across the region, as well as at industrial sites
  • Build a system for the local production of renewable electricity, made available in the form of hydrogen
  • Supply green energy to an eco-neighbourhood
  • Develop "zero carbon as a service" solutions for industrial clients and regions
  • Contribute to local and regional economic development.


ENGIE’s solution


HyGreen Provence, the first commercial project of this scale in France, is underpinned by the construction of a local renewable electricity production system, made available in the form of hydrogen which can potentially be stored in salt cavities at a site operated by Storengy, an ENGIE subsidiary. The final objective is to supply a network of green mobility stations deployed in the region, as well as industrial sites. The expertise, infrastructure and R&D on the production and storage of hydrogen on or below the surface are crucial to the success of such a project.


Expertise and offers


  • Implementation of zero-carbon solutions for industrial clients and regions integrating the entire value chain (production, storage, distribution)
  • 100% renewable energies, including hydrogen
  • Control of the hydrogen value chain: from production to point of use, including electrolysis technology, surface or underground storage
  • Hydrogen mobility at local and regional level: light vehicles, trucks, buses, or commercial vehicles
  • Use of hydrogen for the supply of heat and cooling to an eco-neighbourhood in the urban area
  • Use of hydrogen to develop virtuous industrial uses throughout the region.


“HyGreen Provence is above all an ambitious and innovative project for the region. It will embrace all those desiring consultation and dialogue, particularly the National Parks in Verdon and Luberon. We are therefore involved in the momentum created by the “Vallée des Énergies” together with partners such as the Iter project, the Cadarache CEA, Géomethane and hydroelectricity in Durance. We are thereby contributing to the energy transition in France along with leading industrialists which, through their respective expertise, bring credibility and viability to the requirement for zero carbon emissions” Bernard Jeanmet-Péralta, Chairman of DLVA
