Discover the "Multi-Drain geothermal well" for decarbonising district heating networks.

Heating in buildings is at the core of energy consumption. Thus decarbonise energy sources is crucial to reduce associated emissions. Geothermal district heating is defined as the use of geothermal sources to supply heat to a group of buildings through a distribution network. The main benefits of geothermal sources are provision of local, and flexible renewable energy. Even though there are plenty of geothermal sedimentary reservoirs to use, there is sometimes heterogeneities of geological properties that limited productivity. The goal is then to optimise the draining area and thus to increase the overall energy extracted from the ground. This multidrains technology steps up the efficiency of a geothermal solution.

The multidrains technology has been designed for a new geothermal district heating network in Velizy-Villacoublay, a Paris Basin’s municipality eager to cover more than 60% of the heat demand with geothermal energy. This means satisfying the heating needs of 12,000 houses and saving 22,800 tons of CO2 per year compared to a gas solution.
