GeoRessources is a geosciences research laboratory under the joint supervision of the Université de Lorraine and CNRS-INSU. GeoRessources tackles the societal and industrial challenges posed by the rational use of our underground resources.

Energy transition is at the heart of the work carried out by the laboratory’s research teams. GeoRessources is currently studying:
strategic metals essential to the development of low-carbon technologies,
the use of the subsurface for storage (carbon, radioactive waste, etc.),
the exploitation of new energy sources (geothermal energy, natural hydrogen, helium),
and the development of new and more efficient recycling processes.

This research draws on multidisciplinary scientific expertise in geomechanics, geosciences, chemistry, mathematics, and computer science. GeoRessources also draws on a wide range of other expertise—sociology, geography, history, economics, and law—implemented witin key projects at the local, national, and international levels.
