What is geothermal energy?
Discover our geothermal heat systems overview:
2 wells are drilled until reaching a high
-temperature aquifer. The production well
facilitates the production of geothermal hot
water to the surface, after which the water is
reintroduced into the same aquifer through
the injection well. Such a drilling project is
completed in a 4-month timeframe.

On the surface in the geothermal plant,
the pumped geothermal water releases its
heat through a heat exchanger to the fluid
of a heat distribution network. After
passing through the exchanger, the cooled
geothermal water is reinjected into the
original aquifer. This entire system forms
a primary geothermal loop. If the temperature
of the resource is not suitable for the intended
use, heat pumps and supplementary
heating methods can be used.

The heat distribution network also
operates in a closed loop. Pipelines
transport the hot transfer fluid
(steam, hot water, etc.) over several
kilometers to the base of connected
buildings. Other pipelines return the
cooled fluid to the power station to
be heated once again.

It ensures the distribution of heat from
heat distribution network among the
various residences of the connected
building (public buildings, offices,
collective or individual housing).
The heating of buildings using geothermal heat distribution networks is the primary application of geothermal energy in France.
Nearly 220,000 equivalent housing units are heated in the Paris region, thanks to a heat selling price among the most competitive in national heat distribution networks.
Deep geothermal energy involves harnessing geothermal resources found in aquifers, which are permeable rock formations through which water circulates, located between 400 and 2,500 meters deep. In case of heat production, its development relies on a paired set of boreholes consisting of a production well and an injection well.
When we are talking about electricity production, geothermal water extracted through drilling reaches the surface in the form of a mixture of water and water vapor. The two phases are then separated, and the steam is introduced into a turbine to generate electricity. In France, there are two existing operations, namely Bouillante (Guadeloupe) and Soultz-sous-Forêts (Bas Rhin). Other projects are under consideration in Guadeloupe, Martinique, Réunion, and Mayotte.
