The MéthyCentre project (Centre-Val de Loire region)
Hydrogen
This project will enable the production and storage of three carbon-free gases: hydrogen, biomethane and synthetic methane from renewable electricity and agricultural waste for green mobility (Bio-NGV and hydrogen) and injection into the network. The facility will therefore combine anaerobic digestion (methanisation), green hydrogen production and methanation (also known as "Power-to-Gas").
The production of 5 kg hydrogen per day will supply local service stations, which corresponds to intensive consumption of 20 light vehicles. The renewable gas produced will meet the needs of 800 inhabitants.
The interests of the project:
- Find a solution to the problem posed by the intermittence of renewable electricity production and battery storage.
- Use the CO2 produced by methanisation to recover and produce gas, which considerably reduces greenhouse gases emissions (GHG).

Renewable energy coupling project in Annecy
Shallow geothermal energy
Storengy and the City of Annecy have signed a partnership agreement to enhance geothermal energy and develop new associated concepts.
The project deals with the improvement of the existing energy system at the ”Equipement pour l'enfance Vallin-Fier“. It combines geothermal and solar thermal energy and will serve as a demonstrator for other existing and future building programmes.
The ”Vallin-Fier“ complex, which includes a primary school, a nursery school, a gymnasium and a day-care centre, was initially equipped with a geothermal installation consisting of 18 vertical geothermal probes and a heat pump. To optimise the performance of the installation (summer/winter alternation), the city of Annecy and Storengy worked to find a sustainable energy solution to meet heating needs.
The project involves installing thermal solar panels on the roof of the building to capture heat in the summer, which will be stored underground and then used in the winter to heat the building. This additional heat will complement the heat produced during the summer when the sensor system is used to cool the buildings.
At the same time, two underground temperature measurement probes will be installed in the underground (approximately -130 metres) to monitor its temperature and measure the efficiency of the coupling in real time, a first in France.
Storengy will support the City of Annecy by providing its recognised expertise in the field of geosciences and energy production engineering with a view to deploying coupled geo-energy solutions.
The University of Savoie Mont-Blanc, which is
at the forefront of solar thermal energy, will also be associated with this
project, as will ADEME.

HyPSTER Project
Hydrogen
In the region of Auvergne Rhône Alpes, Storengy and its partners (Axelera, Armines-Ecole polytechnique, Element Energy, ESK, Ineris, Inovyn) develop the first demonstrator of large-scale green hydrogen storage.
This project is going to use a salt cavern of the Storengy storage site in Etrez to connect electrolysis production to industrial and mobility applications.
The salt cavern used has a storage capacity of 44 tons of hydrogen, which is the equivalent of 1,760 hydrogen bus tanks.
HyPSTER is located in a particularly dynamic territory regarding the development of green hydrogen usages with large-scale projects such as Zero Emission Valley (Project ZEV) in the region of Auvergne-Rhône-Alpes, the construction of hydrogen production units and filling stations in the region of Bourgogne Franche Comté. Its geographical location is also an asset for industries which are present in the Chemical Valley.
The ZEV (Zero Emission Valley) project in the region of Auvergne Rhône Alpes comprises 20 hydrogen stations and 1,000 hydrogen vehicles by 2023. Industrial grey hydrogen applications are already existing (especially in the Chemical Valley) and decarbonising the industry and heavy mobility of this sector with green hydrogen is being taken into consideration.
