This year the winner of the Ruggero Bertani European Geothermal Innovation Award 2021 is ENGIE Solutions with its innovative multidrains boreholes well architecture, so the release by the European Geothermal Energy Council (EGEC) in conjunction with the GeoTHERM expo & congress. The project, developed by ENGIE Solutions and built with Antea Group and other partners, can almost double the productivity of a geothermal reservoir.

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.

The multidrains is a technical leap, which allows to cross a geothermal reservoir multiple times. This is the first time that this method, already used in the Oil & Gas sector, has been employed in a deep geothermal project. This configuration maximises the exchange surface and therefore increases the general flowrate of +80% compared to a conventional doublet. This allows the geothermal plant to provide much more power.
