For the first call for projects, 31 letters of intent were submitted and 12 final projects were reviewed by an international jury.

The eight winning projects in this call are mainly focused on the program's second research area, which aims to develop knowledge of the subsurface, assess existing potential, and develop new technologies.

A second call will be launched in early 2026.

Objectives of the call:

  • Identify research strengths that can be mobilized on scientific issues identified around the three scientific areas that structure the program.
  • Propose new, original scientific questions not covered by the work in the targeted projects and relevant to meeting the objectives and challenges of the "Subsurface: a common good" research program.
  • Contribute to the production of knowledge to feed into projects and inter-project issues.
  • Bring about and create new consortia to identify obstacles, propose solutions, and support regional stakeholders in order to foster the co-resilience necessary for underground management in France.

Resources and uses concerned:

  • Mineral resources.
  • Deep geothermal energy.
  • CO2 and hydrogen storage.
  • Native hydrogen.
