Model predictions of global geologic hydrogen resources [PDF]

open access: yesScience Advances
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 occurrence and behavior of natural hydrogen on Earth has been combined with information from geologic analogs to construct a mass balance model to predict the resource potential.

A geophysical investigation of the fairy circles in Nebraska for geologic hydrogen exploration [PDF]

open access: yesScientific Reports
Fairy circles are subcircular surface depression features that are widely distributed all over the world and they are commonly considered as a potential indicator to the presence of subsurface geologic hydrogen.

Finding natural $$\hbox {H}_{2}$$ generation zones in Midcontinent Rift in the U.S. by identifying the geophysical signatures of a serpentinization system [PDF]

open access: yesScientific Reports
Hydrogen 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.

Natural sources and conditions of geological hydrogen generation (in the context of hydrogen depositssearches)

open access: yesГеофизический журнал, 2022
World energy problems can largely be solved in the event of discovering huge amounts of gaseous hydrogen in a free state, which is considered as a promising alternative to the reserves of traditional fossil fuel in the earth’s crust.

Pore‐Scale Modeling of Carbon Dioxide and Hydrogen Transport During Geologic Gas Storage

open access: yesGeophysical Research Letters
Geologic storage of CO2 and H2 are climate‐positive techniques for meeting the energy transition. While similar formations could be considered for both gases, the flow dynamics could differ due to differences in their thermophysical properties.

The role of geophysics in geologic hydrogen resources

open access: yesJournal of Geophysics and Engineering
Abstract Transition to cleaner energy sources is crucial for reducing carbon emissions to zero. Among these new clean energy types, there is a growing awareness of the potential for naturally occurring geologic hydrogen (H2) as a primary energy resource that can be readily introduced into the existing energy supply.

Geological Hydrogen Storage: Geochemical Reactivity of Hydrogen with Sandstone Reservoirs [PDF]

open access: yesACS Energy Letters, 2022
The geological storage of hydrogen is necessary to enable the successful transition to a hydrogen economy and achieve net-zero emissions targets. Comprehensive investigations must be undertaken for each storage site to ensure their long-term suitability and functionality.
