Deep crustal production of hydrogen (H2) is a potential source of primary energy if
recoverable accumulations in geological formations are sufficiently large. We report direct …

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 …

Hydrogen (H2) is among the most common and widely utilized electron donors in microbial
metabolism. This is particularly true for microorganisms that inhabit subsurface …

The Samail Ophiolite in Oman, the largest exposed body of ultramafic rocks at the Earth's
surface, produces a continuous flux of hydrogen through low-temperature water/rock …

Metamorphic fluids in subduction zones carry C–H–N–O–P–S species, which are crucial for
sustaining subsurface microbial life at shallower crustal depths in the forearc region …

Naturally produced by geochemical processes in the Earth's crust, geologic hydrogen is
recently considered as an alternative energy source that may help decarbonize the energy …

Subsurface natural hydrogen accumulations that can be economically and safely recovered
are a major target of the present roadmap towards the use of hydrogen as an alternative and …
