Native H2 Exploration in the Western Pyrenean Foothills
Geochemistry, Geophysics, Geosystems, 2021 Native hydrogen (H2) may represent a new carbon free‐energy resource, but to date there is no specific exploration guide to target H2‐fertile geological settings. Here, we present the first soil gas survey specifically designed to explore H2 migration in

Hydrogen Emanations in Intracratonic Areas: New Guide Lines for Early Exploration Basin Screening
Geosciences, 2021 Offshore the emissions of dihydrogen are highlighted by the smokers along the oceanic ridges. Onshore in situ measurements in ophiolitic contexts and in old cratons have also proven the existence of numerous H2 emissive areas.

Reassessing the role of magnetite during natural hydrogen generation
Frontiers in Earth Science, 2023 Interactions between water and ferrous rocks are known to generate natural H2 in oceanic and continental domains via the oxidation of iron. Such generation has been mainly investigated through the alteration of Fe2+-silicate and some Fe2+-carbonates.
