Déploiement de la géothermie profonde en région Centre-Val de Loire : un argumentaire à destination des acteurs locaux basé sur des analyses sociales, économiques et environnementales

The Centre Val-de-Loire region sees deep geothermal energy as a virtuous energy solution for the region, but to date it has not been widely deployed. To encourage its use, the region has financed a research project of regional interest, called "AMIGO". The project is being co-ordinated by BRGM in partnership with LEO (Laboratoire d'Économie d'Orléans), AFPG (Association Française des Professionnels de la Géothermie), AMORCE (Association d'accompagnement des collectivités et des acteurs dans la transition énergétique) and AgreenTech Valley (national cluster dedicated to digital technologies for plant-based industries). Its aim is to draw up a set of arguments to help local authorities and private-sector players in the region to choose between the various possible sources of renewable energy for district heating networks, industrial processes or heating crops in greenhouses. To develop this argument, the phases of the project are: (1) to understand the position of the stakeholders with regard to deep geothermal energy, and (2) to gather the key information in the territorial context (socio-economic and environmental aspects of a deep geothermal energy project, information on the geothermal resource, demand for heat in the territory). This article presents the progress made in the process of constructing the argument, in particular the results of (1) the analysis of the positioning of stakeholders in the region and (2) the economic and environmental analysis of a deep geothermal energy project.
