Microbial taxa related to natural hydrogen and methane emissions in serpentinite-hosted hyperalkaline springs of New Caledonia [PDF]

Frontiers in Microbiology, 2023
The southeastern part of New Caledonia main island (Grande Terre) is the location of a large ophiolitic formation that hosts several hyperalkaline springs discharging high pH (∼11) and warm (<40°C) fluids enriched in methane (CH4) and hydrogen (H2 ...

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.

Natural hydrogen potential and basaltic alteration in the Asal–Ghoubbet rift, Republic of Djibouti

BSGF - Earth Sciences Bulletin, 2023
The Asal–Ghoubbet active rift in the Republic of Djibouti is a site of interest for geothermal energy and natural hydrogen, and previous studies have indicated that dihydrogen (H2) emanates from this rift.
