Storengy is a key player in the development of geothermal energy, with almost 70 years of experience in underground exploitation and more than 600 wells, Storengy brings its state-of-the-art industrial expertise to the development of high- and low-temperature geothermal sites. From catchment studies to subsurface operation, we support our partners in their geothermal projects, whether for district heating networks or power generation.

Power production, or deep geothermal energy

This type of production is called deep geothermal energy, because energy is drawn from depths of between 2,000 and 3,000 metres at a temperature above 150° C. Deep geothermal energy transforms underground heat into power. As this heat is constantly replenished from the Earths core it is completely renewable. This type of geothermal energy is most easily found in geologically active environments.

Heating and cooling grids, or low-temperature geothermal energy

Low-temperature geothermal energy is energy drawn from several hundred meters underground, typically at a temperature between 30° and 90° C. It is the main source of geothermal energy used by heating and cooling grids. Naturally occurring subsurface energy is used to supply heating and cooling to a large area such as a city or an industrial site. It tends to be a centralised solution since production resources are pooled in order to provide heating and cooling to the area. Storengy is participating in projects in three parts of France: the Paris region, Aquitaine and Alsace and is actively looking for opportunities elsewhere including in the UK.

Decentralised heating and cooling, or very low-temperature geothermal energy

Very low-temperature geothermal energy comes from a few dozen meters underground and can heat small spaces using heat pumps. It tends to be a decentralised solution since energy is produced in a specific location such as a building or an eco-neighbourhood.
