Using the subsurface to contribute to the energy transition and decarbonisation

The energy transition and decarbonisation strategies now include the potential use of the subsurface as a source of energy (geothermal energy, heat storage, native hydrogen) or energy vector (synthetic hydrogen), as well as its use as a storage site (CO₂, hydrogen, radioactive waste). Underground space can therefore play an important role in the future low-carbon energy mix, complementing other renewable energies and meeting the targets set at the European level by the Net-Zero Industry Act. BRGM is mobilising its know-how and R&D resources to explore, study and exploit the potential of the subsurface, particularly at the regional level, thereby promoting the implementation of economically viable systems with low environmental impact.
