Christophe Rigollet
Christophe Rigollet has a phD in Geosciences from Mines Paris Tech. He began his career in 2001 at Gaz de France (ENGIE) in natural gas exploration and storage domains, then joined the French geological survey (BRGM) as director of the Sedimentary Basins unit and deputy director of the Geology Department. In 2011, Christophe began a career as an international geoscience consultant within the SGS group in Netherlands then CVA (www.group-cva.com) as Geoscience Director.
Christophe is driven by the desire to promote “underground technical solutions” to respond to major societal challenges such as energy resources, raw materials and geological storage. Sensitive to environmental issues, he is particularly involved in the search for new solutions for the success of the ecological transition, particularly in the areas of natural hydrogen, geological storage of hydrogen, deep geothermal energy and CO2 geological storage.
Christophe actively contributes to boosting the national network of subsurface stakeholders, convinced of the capacity of public and private stakeholders to respond to these challenges by pooling research efforts and structuring a commercial offer based on complementary skills.
In 2020-21, he is actively involved in the co-founding of EARTH2 with 45-8 Energy and AVENIA, a cluster program to create a common European banner, able to bring together the actors of underground hydrogen.
The Armorican Massif, Breton peninsula, is located in the far west of France. It consists of Proterozoic and Paleozoic sedimentary, magmatic and metamorphic formations that were deformed by the Cadomian and Variscan orogenies. It extends to the east under the Mesozoic and Cenozoic sedimentary series of the west of the Paris basin of which it constitutes the bedrock. Although lacking obvious targets (e.g. large mantle rock bodies), the variety of rocks that make up the Armorican basement and its high-density fault network of various age are worth exploring for the formation of hydrogen and its migration. The geochemical surveys we have carried out over the last two years highlighted hydrogen anomalies in soils. In the Brittany region, we will study the possible accumulation in the fractured basement. Further east, in the Paris Basin, hydrogen could have been trapped in the Mesozoic sedimentary reservoir formations (Lefeuvre et al., 2024).
