Our Team
CEO – Dr. Eric C. Gaucher
Eric C. Gaucher is a geochemist expert. His work focuses on water–rock–gas interactions at the laboratory scale up to basin scale using experimental, field and numerical modeling methods. He is committed in all geo-energy sectors (Nuclear Waste management, CO2 & H2 storage, Geothermal energy, lithium extraction from brines, evolution of porous medium in carbonate reservoirs, environmental concerns related to oil&gas shale). He is a leader for Natural H2 Exploration.
After 19 years in academic research (CEA, BRGM in France and the University of Bern in Switzerland) and 10 years in industry (TotalEnergies), he is now building bridges between the worlds of research and industry.
He graduated with two master degrees in 1993. The first was a Master of Earth Sciences from Lyon I University & École Normale Supérieure. The second was a Master of Hydrology from the Paris Orsay University. He also completed his water-rock interaction PhD with CEA and the Paris VII University in 1998.
Focused on solving industrial problems using the most advanced scientific methods, he has solved problems linked to the stability of clays and cements, CO2 control by rocks and, carbonate diagenesis. Since 2016, he has been developing exploration methods for natural hydrogen gas (H2) and assessing the reserves of this new geo-energy.
He is the task leader for natural hydrogen (Task 49) in the International Energy Agency‘s Hydrogen TCP.
He is also in member of the Geochemical Society.
