Introduce us to StrateGéo and DrillHeat, and your link?
Christopher Luttman: Drillheat is a construction company specializing in surface geothermal energy, more specifically in the implementation of vertical geothermal probes. It is a subsidiary of the Arverne group, a deep geothermal operator.
Jean-Loup Lacroix: StrateGéo is a hydrogeology and geothermal design office. We are primarily involved in geothermal operations as designers and project managers of the solution on the underground side.
We are both members of the AFPG, which lists a hundred members and federates the actors of the profession. The association intervenes at different scales in shallow and deep geothermal projects.
How can geothermal energy make it possible to aim for carbon neutrality by 2050?
CL: Adopted in 2015, the National Low Carbon Strategy (SNBC) has the goal of carbon neutrality by 2050, that is, a 70% reduction in GHG emissions compared to 1970. To achieve this carbon neutrality, the Program Multiannual Energy (PPE) establishes a renewable thermal energy. production target for geothermal heat pumps of 7 TWh in 2028 and 10 TWh in 2033 (on a current basis valued at 4.6 TWh). The AFPG estimates that the potential of geothermal heat pumps amounts to more than 100 TWh by 2040. To be in line with these objectives, the share of geothermal energy in the energy mix must increase significantly in the coming years.
How is your market evolving, particularly with regulations?
CL: Geothermal energy has largely demonstrated its performance in tertiary buildings. In communities, owners pay more and more attention to consumption, knowing that heating represents an important part of the total cost of building management. Meanwhile, the individual market is timidly recovering. The sudden decline for almost 10 years followed by 3 years of stagnation finally gave way to a renovation of the geothermal heat pump in individual homes.
JLL: Two regulations have an impact: the RE 2020, which refers to the carbon impact and energy production of new buildings, and the tertiary decree, which asks all owners of buildings of more than 1,000 m2 to reduce their energy consumption . Geothermal energy is a solution that reduces consumption by 4 or 5, and therefore the carbon footprint. It can be adapted to any type of building and associated with any form of energy.
What is the news about geothermal energy right now?
JLL: The projects that drive us are the Olympic and Paralympic villages, which add up to 650,000 m2 that will be supplied by a heating and cooling network with 80% renewable energy, much of which will be covered with groundwater geothermal energy. We are also in a greening of the freshness network of Paris, in Porte de la Chapelle. And we are working on several tertiary buildings from 10 to 30,000m2, which will be fed by 80% geothermal probes.
CL: Large industrial or luxury groups are also opting for geothermal energy with carbon neutrality targets for 2030-2040! That’s why we work for Hermès, L’Oréal, Urgo, Ruinart…
