Geologic molecular hydrogen (H 2) occurs in the subsurface and vents and seeps at the
surface. However, this valuable natural resource is under-utilized in the economy because …

The dissolution rates of olivine have been considered by a plethora of studies in part due to
its potential to aid in carbon storage and the ease in obtaining pure samples for laboratory …

Around 50% of humankind relies on groundwater as a source of drinking water. Here we
investigate the age, geochemistry, and microbiology of 138 groundwater samples from 95 …

Little is known of acetogens in contemporary serpentinizing systems, despite widely
supported theories that serpentinite-hosted environments supported the first life on Earth via …

The origin and early evolution of photosynthesis are reviewed from an ecophysiological
perspective. Earth's first ecosystems were chemotrophic, fueled by geological H2 at …

Groundwater co-contaminated by vanadium (V)(V (V)) and nitrate requires efficient
remediation to prevent adverse environmental impacts. However, little is known about …

The capacity for molecular hydrogen (H2) to hydrogenate oxygen and carbon is critical to
the origin of life and represents the basis for all known life-forms. Major sources of H2 that …

Natural dihydrogen (H 2) exploration is now active in various countries, but tools and
workflows that help to characterize prospective zones are still poorly defined. This review …

Natural hydrogen (H2) has gained considerable attentions as a renewable energy resource
to mitigate the globally increasing environmental concerns. Low‐temperature …

Life as we know it would not exist without water. However, water molecules not only serve as
a solvent and reactant but can also promote hydrolysis, which counteracts the formation of …
