The 'Subsoil' (resources) exploratory PEPR

The subsoil is a veritable reservoir of resources that are necessary for the energy transition. It is a major source of decarbonised geothermal energy while also a place for storing energy (H2) and waste (CO2) which hosts essential water reserves.
The 'Subsoil' PEPR's objectives - as defined in response to the multiple issues linked to the subsoil's conditions - are:

  • To define the conditions for responsible and sustainable use of the subsoil in the framework of different scenarios for economic, energy and technological evolution while also taking socio-technical trajectories into account;
  • To develop a framework to limit conflicts and impacts, define strategies for the study and conservation of archives contained in the subsoil, create the right conditions for dialogue and arbitration about subsoil-related activities and support initiatives aimed at protecting and enhancing the subsoil which is considered to be a common heritage; 
  • To structure a broad community of researchers in the Earth and environmental, social, environmental, economic and legal sciences and federate the even broader community made up of researchers, citizens, decision-makers and industrialists around these issues.
