A life cycle cost analysis framework for geologic storage of hydrogen : a user's tool. [PDF]

open access: yes, 2011
The U.S. Department of Energy (DOE) has an interest in large scale hydrogen geostorage, which could offer substantial buffer capacity to meet possible disruptions in supply or changing seasonal demands.

Bubble Coarsening Kinetics in Porous Media

open access: yesGeophysical Research Letters, 2023
Bubbles in subsurface porous media spontaneously coarsen to reduce free energy. Bubble coarsening dramatically changes surface area and pore occupancy, which affect the hydraulic conductivity, mass and heat transfer coefficients, and chemical reactions ...

Overview of geologic storage of natural gas with an emphasis on assessing the feasibility of storing hydrogen. [PDF]

open access: yes, 2009
In many regions across the nation geologic formations are currently being used to store natural gas underground. Storage options are dictated by the regional geology and the operational need. The U.S.

Geophysical controls of chemical disequilibria in Europa

open access: yesGeophysical Research Letters, 2016
The ocean in Jupiter's moon Europa may have redox balance similar to Earth's. On Earth, low‐temperature hydration of crustal olivine produces substantial hydrogen, comparable to any potential flux from volcanic activity.

The Influence of Growth Rate on 2H/1H Fractionation in Continuous Cultures of the Coccolithophorid Emiliania huxleyi and the Diatom Thalassiosira pseudonana. [PDF]

open access: yesPLoS ONE, 2015
The hydrogen isotope (2H/1H) ratio of lipids from phytoplankton is a powerful new tool for reconstructing hydroclimate variations in the geologic past from marine and lacustrine sediments. Water 2H/1H changes are reflected in lipid 2H/1H changes with R2 >

Mechanism and Characteristics of CH4/CO2/H2O Adsorption in Lignite Molecules

open access: yesGeofluids, 2021
Adsorption characteristics of coalbed methane (CBM) are significant to investigate the absorption of coal, shale, and porous media. In particular, adsorption characteristics of CH4, CO2, and H2O play an important role in predicting CBM output and ...

Toward a Fundamental Understanding of Geological Hydrogen Storage

open access: yesIndustrial & Engineering Chemistry Research, 2022
Geological H2 storage plays a central role to enable the successful transition to the renewable H2 economy and achieve net-zero emission in the atmosphere. Depleted oil and gas reservoirs are already explored with extensive reservoir and operational data. However, residual hydrocarbons can mix with injected H2 in the reservoirs.

Assessing the Effect of Mineralogy and Reaction Pathways on Geological Hydrogen (H2) Generation in Ultramafic and Mafic (Basaltic) Rocks

open access: yesHydrogen
This study evaluates the impact of mineralogy, elemental composition, and reaction pathways on hydrogen (H2) generation in seven ultramafic and mafic (basaltic) rocks. Experiments were conducted under typical low-temperature hydrothermal conditions (150 °
