The role of geophysics in geologic hydrogen resources

Journal 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]

ACS 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.

Environmental risks and opportunities of orphaned oil and gas wells in the United States

Environmental Research Letters, 2023
Hundreds of thousands of documented and undocumented orphaned oil and gas wells exist in the United States (U.S.). These wells have the potential to contaminate water supplies, degrade ecosystems, and emit methane and other air pollutants. Thus, orphaned

What Pulsating H₂ Emissions Suggest about the H₂ Resource in the Sao Francisco Basin of Brazil

Geosciences, 2020
Proterozoic sedimentary basins very often emit natural hydrogen gas that may be a valuable part of a non-carbon energy infrastructure. Vents in the Sao Francisco Basin in Brazil release hydrogen to the atmosphere mainly during the daylight half of the ...

Underground hydrogen storage: A critical assessment of fluid-fluid and fluid-rock interactions [PDF]

, 2023
Underground hydrogen storage (UHS) is the injection of hydrogen into the geologic porous medium for subsequent withdrawal and reuse during off-peak periods to contribute to the energy mix.

Transport Cost for Carbon Removal Projects With Biomass and CO2 Storage

Frontiers in Energy Research, 2021
Strategies to remove carbon from the atmosphere are needed to meet global climate goals. Promising strategies include the conversion of waste biomass to hydrogen, methane, liquid fuels, or electricity coupled with CO2 capture and storage (CCS).

On geological hydrogen

Geofizicheskiy Zhurnal, 2020
Formation of geological (abiogenous) hydrogen in the interior is connected with two groups of hypotheses: production of secondary hydrogen in the Earth’s crust and upper mantle as a result of its emission from water and some minerals as well as discharge of primary hydrogen from the core and lower mantle accumulated in the depths during accretion of ...
