Sylvain Waserman, Chairman and CEO of the French ecological transition Agency (Ademe).

Why did you sign a framework agreement with BRGM?

Sylvain Waserman - In January 2024, ADEME signed a five-year framework agreement with BRGM, strengthening our collaboration in the interests of sustainable management of subsurface resources. While our relationship goes back a long way, it has now taken on a new dimension. Geothermal energy is a huge challenge! Of all existing technologies, particularly for building heating networks, only one truly meets the challenges of the ecological transition, namely the need for heat in winter (mitigation, with a reduced carbon impact) and cooling in summer (adaptation, particularly to severe heat waves): near-surface or deep geothermal energy. This partnership comes at a time when pooling our know-how can give a boost to geothermal energy and the use of the subsurface to meet the challenges of the ecological transition and strengthen France's energy sovereignty.
