expertise1

Within the ENGIE Group and in collaboration with its other subsidiaries and partners, Storengy positions itself as a key player in the development of geothermal energy.

With more than 60 years of experience in the development and exploitation of underground natural gas storage, Storengy enjoys a state-of-the-art expertise in geoscience and drilling with more than 600 wells.

ENGIE Group is one of the few operators to integrate all the necessary expertise in the development of solutions in centralized and non-centralized geothermal energy to produce heat and/or electricity in response to the challenges of energy transition around the world.

Heat production

Arcueil-Gentilly
In 2013, ENGIE Réseaux won the tender to design, build and operate a new heating network in the communes of Arcueil-Gentilly, in the Parisian region, as part of a public service delegation.
Storengy specializes in geothermal doublet drilling. Expanding this synergy and the success of the solution proposed have paved the way for new projects.

 

Village Nature
In 2015, Storengy joined forces with ENGIE Réseaux and two investment funds to design, build, finance, and operate the geothermal heating network of the new Village Nature and Disneyland® Paris park.
The exploration permit is valid for 25 years as assistance for the person responsible for the work (subsurface) for a private-investment project run by Eurodisney and Pierre & Vacances Center Parcs.

 

PLAINE DE GARONNE ENERGIES – Bordeaux Métropole
In 2017, the city of Bordeaux selected the ENGIE tender, won by Storengy and ENGIE Cofely to design, build, and operate a new heating network in Bordeaux, as part of a public service delegation for a period of 30 years.
This operation is symbolic since it includes, on the one hand, the exploration of a deep reservoir (Jurassic period) and, on the other, the expansion of a first geothermal doublet in the region of Aquitaine.

Mulhouse
Since August 2015, Storengy has been holding an exclusive permit for geothermal accommodations in Mulhouse and runs geological surveys to supply the urban area with renewable heating.

 

Power generation

In cooperation with Reykjavik Geothermal for the development of geothermal projects in Mexico
Storengy and Reykjavik Geothermal are cooperating on geothermal projects in Mexico to supply an expanding Mexican market with power.
They work at the development of a portfolio of 3 exploration permits in the states of Puebla and Nayarit.

Cooperation with TLS Geothermics
In June 2017, Storengy and TLS Geothermics signed a cooperation agreement in the fields of High Temperature Geothermal Energy.
This agreement allows the cooperation on R&D projects aimed at limiting the risks and the costs of the exploration phase and developing the production of power in France and in Europe.

 

Indonesia
Storengy lends its expertise to the ENGIE Group projects run in Indonesia and plays a role in both stages of qualification and the development of geothermal resources.
In the beginning of 2017, within the PT Supreme Energy Muara Laboh consortium, ENGIE launched the first phase of high temperature geothermal energy, that is, 80 MW of power production.

Heat and cold production—Decentralized solutions

Cooperation with ENSEGID
In January 2017, Storengy and ENSEGID signed a cooperation agreement to collaborate on innovative projects of geothermal energy and seasonal energy storing such as the Aquifer Thermal Energy Storage (ATES), for which there are no projects in the region of Nouvelle-Aquitaine, or the Borehole Thermal Energy Storage (BTES) or the geothermal probe fields.
These local projects which are decentralized and adapted to areas undergoing urban renewal and to new eco-areas provide innovative solutions for the renewable energy storage, notably heat and cold.

 

BTES Smart
In 2017, Storengy decided to launch pilot test to heat the government buildings and technical offices on one of the storage sites, Chémery, with the help of probe field. Replenishing the probe field will be done in Summer by means of thermal solar panels across 265 m2.
Thanks to this project, CO2 emissions will be reduced to 80% compared to the current gas furnace emissions in tertiary buildings.

 

Repurposing the mines into energy (heat) storage
In 2017 Storengy played a role in the valuation surveys of a geothermal energy storage solution on 2 previously existing mine sites. This topic is part of the solutions to be implemented closest to the context and needs of a project.
Repurposing mines is a subject matter which is part of the topics included in a decentralized and locally applied global energy storage approach which is adopted by Storengy.

 

Introducing services

Thanks to its many performances in geothermal energy, Storengy has a real added-value:

  • Expertise in subsurface (assessment of field capacity, setting up regulatory files), in drilling operation (borehole construction, engineering and supervision)
  • Operating and maintenance of wells (monitoring and optimisation the production and maintenance of assets)
  • Geothermal resource management
  • Control over risks and the uncertainty of subsurface conditions

 

Our references

In France, Storengy is member of the French Association of Geothermal Professionals (AFPG) and of Pole Avenia (competitive cluster in geosciences).
