Dr. Eric Gaucher received from the University of Bern the Faculty Teaching Award (Faculty of Sciences) for this course.


Natural Hydrogen Exploration & Prospection
LH2G can assist you on the exploration and prospecting of natural hydrogen and associated gases (He, 220Rn & 222Rn). We use our advanced expertise and our mobile laboratory to identify high potential areas by estimating reserves and assessing the economic viability of projects.
LH2G is a propect generator (For example, LH2G is a minor shareholder of 45-8 Grand Rieu license). We carry out prospecting and exploration operations in the field of natural hydrogen, in collaboration and for third parties.

Consulting – Natural Hydrogen
As an investor interested in Natural Hydrogen (geologic hydrogen), you want an independent assessment of the quality of a prospect. Our method evaluates the available documentation on the basis of a multi-criteria analysis. We will assess the information available from the various fields of geoscience. LH2G will investigate the presence of source rock, the timing of hydrogen generation, the migration paths and the potential for underground gas trapping, and we will provide an estimation of natural hydrogen volumes. Another key point, gas quality and the presence of other economic gas accumulations will also be studied. Our method makes it possible to compare several prospects to establish a ranking of the best opportunities and enhance the security of your investment.
As an exploration company, you want to challenge your exploration method and check that your level of understanding of the geological system is sufficient. So LH2G propose to review your prospect and your method of investigation. With the help of our network of partner companies, we can propose technical solutions to increase your level of understanding of the hydrogen system and to increase your chances of successful exploration.


Consulting – Water/rock/gas Interaction
With 30 years’ experience in geochemistry, LH2G’s team has solved numerous scientific and technical problems on the field of reactivity in water/rock/gas systems. LH2G can therefore implement analytical and experimental methods at its university partners, as well as the most sophisticated chemistry-transport computing methods. Adapting thermodynamic databases to your problem is also key to the correct numerical representation of your system.
You can contact us on the following subjects:
– Groundwater (GW) chemistry and isotopes (data acquisition methods, data quality , data origin, equilibrium with aquifer rocks, aquifer connectivity, groundwater mixing, effect of temperature changes, scaling deposits, origin of dissolved gases).
– Modeling disturbed systems (stability of caprocks, cement-clay interactions, source rock oxidation, metal pollution, H2S karstification, anhydrite/gypsum transformation)
– Interpretation and numerical modelling of carbonates diagenesis (origin of continental carbonate deposits, dolomitization, silicification…)
– Identifying the origin of natural gas (shale gas leaks). Limiting metal contamination during shale gas and metal mining operation.

Scientific Research
Our team study natural resources, such as minerals, hydrocarbons and groundwater, to better characterize them, determine their origin and optimize their sustainable exploitation. We are particularly interested in geologically related renewable energy sources such as hydrogen and geological storage of CO2.
LH2G are members of research projects focused on natural hydrogen such as : H2NA (Pyrenees, France), Natural Hydrogen Stimulation with ARPA-E (USA), Deep-time Digital Earth (France, China)…
Our team can carry out scientific research operations by itself, in collaboration or for third parties.
