Geothermal energy - Presentation

Storengy is developing geothermal projects to produce green electricity or heat and cold networks.

Find out more about our geothermal solutions

Geothermal energy is energy from the earth. Geothermal energy is used to produce heat or cold and to generate electricity. It is a renewable energy, local and respectful of the environment, combining energy performance and economy. 

Storengy designs, develops and operates geothermal sites for its customers around the world. Depending on local energy needs and the characteristics of the subsoil, geothermal energy can be used to produce green electricity or heat and cold to supply cities, industrial sites or even eco-districts

Let's talk about geothermal energy... 

Within the ENGIE Group, Storengy is a major player in the development of geothermal energy, in association with other Group subsidiaries and partners. With nearly 70 years of subsoil development and a fleet of 600 wells, Storengy has real industrial experience in the development of high and low temperature geothermal sites. From basin studies to subsoil operation, we support our partners in their geothermal projects, district heating networks or electricity production.

“By 2030, Storengy's goal is to become a leader in geothermal energy.”

THE 3 MAIN SEGMENTS OF GEOTHERMAL ENERGY AT STORENGY 

Geothermal energy for buildings and eco-districts 

Present up to a few tens of meters deep, extremely low energy geothermal energy can be used to heat small installations using heat pumps. The production is said to be decentralised because it is concentrated on a specific location: a building or an eco-district for example. This type of geothermal energy is available everywhere, whatever the local geography. 

Heating and cooling networks 

Low-energy geothermal energy refers to an energy drawn from a few hundred meters deep for a temperature between 30 and 90 degrees. It is the main source of geothermal energy that can be used by heating and cooling networks. The principle is to use the energy naturally present in the subsoil to supply a large area with heat and cold. It can be a city or an industrial site for example. This solution is said to be centralised because the production means are pooled to meet the heating and cooling needs of the area. This type of geothermal energy is used in 3 areas in France: the Paris, Aquitaine and Alsace basins. 

Electricity production or deep geothermal energy 

This type of production is called deep geothermal energy because the energy is drawn from depths of between 2,000 meters and 3,000 meters at a temperature of over 150 degrees. Deep geothermal energy makes it possible to transform the heat from underground into electricity. It is then said that this electricity produced is renewable. This type of geothermal energy is found in geologically active environments.
