The Paris-Orly Airport and the athlete’s village of the 2024 Olympic Video games – these are simply a number of the locations in France that profit from geothermal heating.
France is among the pioneers of geothermal heating in Europe, having constructed and put in geothermal heating vegetation for the reason that Nineteen Eighties. To additional show simply how important geothermal heating has been for France, the French Geological Survey (BRGM) has printed a incredible infographic on some main areas which are at present being heated with geothermal power.
This infographic had additionally been printed within the 27th version of the Géosciences journal, launched in September 2023.
Radio France
Because the day of its inauguration on 14 December 1963, the Maison de la Radio has been heated and cooled by deep geothermal power, drawing on the Albien aquifer to warmth and funky the constructing. It was the primary constructing to be heated by geothermal power in France.
This heating system has enabled the French radio firm “to keep away from being affected by the financial penalties of the varied oil crises which have occurred for the reason that Seventies. It’s partly because of this heating system that Radio France has been in a position to hold its budgets beneath management”, in response to Jean-Luc Hees.
Since 2010, the Maison de la Radio has switched to a near-surface geothermal power system, in an effort to adjust to new legislative necessities, whereas additionally assembly their premises’ increasings wants when it comes to cooling.
Aéroports de Paris
A complete of fifty% of the heating required at Orly Airport will probably be equipped by geothermal power by 2024. At present, geothermal power is used to supply 35% of the heating necessities (equal to the consumption wants of 5,000 houses). It’s used to warmth a part of the buildings and to provide sizzling water.
The airport additionally makes use of the waste warmth produced by the waste-energy restoration plant in Rungis. The proportion of geothermal power will probably be elevated by the addition of a warmth pump, which is able to increase the power potential.
Rennes
Geothermal power is now used to warmth and provide sizzling water to houses located above the Métro (underground) stations in Rennes. And this power is produced through the Métro itself!
In 2021, an authentic system was put in immediately within the ground slabs and vertical partitions of 4 Rennes Métro stations in an effort to produce warmth. This progressive challenge is managed by BRGM. Your complete floor of the stations is now used as a warmth exchanger. This technique ought to have the capability to cowl a really giant proportion of the heating wants of the buildings above the stations. In the end, some 112 houses will profit from geothermal heating.
Paris 2024
It’s official: the athletes’ village (positioned in St Ouen and St Denis) for the Paris 2024 Olympic Video games, the encircling city growth space (ZAC) and the Pleyel Tower will obtain 68% of their energy from geothermal power. The power will probably be used for heating and cooling and will probably be equipped and managed by CPCU – the Paris City Heating Firm. The water used will probably be drawn from three aquifers, in a system combining near-surface geothermal power and thermo-fridge pumps.
The amenities will probably be used over the long run, for the reason that athletes’ villages will probably be transformed into lodging and places of work after the Video games. This initiative will contribute to “delivering low-carbon Olympic and Paralympic Video games. The purpose is to scale back carbon emissions by half. As such, we purpose to decarbonise 35% to 40% of constructing development and greater than 60% of constructing use,” explains Antoine du Souich, Director of Technique and Innovation at Solideo, one of many challenge’s companions, at the side of Engie and SMirec.
