Finding natural $$\hbox {H}_{2}$$ generation zones in Midcontinent Rift in the U.S. by identifying the geophysical signatures of a serpentinization system [PDF]
Scientific ReportsHydrogen is gaining attention as an energy source for its zero CO2 emission. Hydrogen may be manufactured by breaking down water using solar and wind energy. However, the high cost of manufactured hydrogen makes it uneconomical.

Serpentinization as the source of energy, electrons, organics, catalysts, nutrients and pH gradients for the origin of LUCA and life [PDF]
Frontiers in Microbiology, 2023 Serpentinization in hydrothermal vents is central to some autotrophic theories for the origin of life because it generates compartments, reductants, catalysts and gradients.

Geochemistry, Geophysics, Geosystems, 2014 At slow spreading ridges, axial detachment faults exhume mantle‐derived peridotites and hydrothermal alteration causes serpentinization in a domain extending more than 1 km next to the fault.

Geophysical Research Letters, 2017 Previous studies have estimated that mantle serpentinization reactions generate H2 at a rate of 1010–1012 mol/yr along the global mid‐ocean ridge (MOR) system.

Dataset for H2, CH4 and organic compounds formation during experimental serpentinization
Geoscience Data Journal, 2021 Serpentinization refers to the alteration of ultramafic rocks that produces serpentines and secondary (hydr)oxides under hydrothermal conditions. Serpentinization can generate H2, which in turn can potentially reduce CO/CO2 and produce organic molecules ...

The Planetary Science JournalSalty aqueous solutions (brines) occur on Earth and may be prevalent elsewhere. Serpentinization represents a family of geochemical reactions where the hydration of olivine-rich rocks can release aqueous hydrogen, H _2(aq) , as a byproduct, and hydrogen ...

BSGF - Earth Sciences Bulletin, 2022 The ophiolite of Sivas (Turkey) was studied in order to define the chronology of different alteration events related to a series of serpentinization and carbonation episodes. Six samples were investigated, representative of different types of ophicalcite

Observational constraints on the process and products of Martian serpentinization
, 2023 The alteration of olivine-rich rocks to serpentine minerals, (hydr)oxides, and H2(aq) through serpentinization is long thought to have influenced the distribution of habitable environments on early Mars and the evolution of the early Martian hydrosphere ...
