Hydrogen is a promising clean energy source with geological reserves widely distributed
globally, offering an annual flow exceeding 23 trillion grams. However, natural hydrogen …

Geologic hydrogen could be a low-carbon primary energy resource; however, the
magnitude of Earth's subsurface endowment has not yet been assessed. Knowledge of the …

In the natural gas era, an underground gas storage capacity of more than 10 trillion cubic
feet has been developed globally. However, as the global energy demand shifts toward …

Underground hydrogen storage (UHS) is an effective means to solve large-scale hydrogen
energy storage. The depleted gas reservoirs can be used as the potential UHS targets due …

Serpentinization is an important geochemical process producing natural hydrogen (H 2),
and mafic and ultramafic serpentinized rocks, typically occurring in ophiolites and peridotite …

Ions in seawater hinder direct sewage electrolysis due to the extreme corrosion of Cl− to the
anode and reaction of Mg2+ and Ca2+ on the cathode producing solid substances, which …

This study investigates natural hydrogen (H2) occurrences in the Paris Basin, using Optical
Character Recognition (OCR) technology to analyze an extensive, yet underexploited …

Ultramafic rocks in ophiolites are known as source rocks of abiotic hydrogen (H 2) and
methane (CH 4), due to serpentinization and successive CO 2 hydrogenation. Ophiolites are …

The origins of natural hydrogen in natural gas systems of sedimentary basins and the
capacity of these systems to store hydrogen remain inadequately understood, posing crucial …

Helium, a scarce strategic resource, and hydrogen, a zero‑carbon clean energy source, are
abundantly stored in sedimentary basins and are essential components of underground …
