“…Specifically, it was previously confirmed that hysteresis depends on the size of the necks and cavities, and as shown in Figure , the highest hysteresis is seen in HKUST-N; this can explain a significant increase in H 2 adsorption capacity because H 2 interaction is enhanced in the smaller cavities and neck pores. Additionally, capillary pores at a high surface area can lead to a stronger interaction with H 2 , thus enhancing its adsorption capacity because ultramicropore size can dominate the overlapping of the potential fields between the molecules of H 2 and surface of the pores …”

High-pressure adsorption of CO 2 , H 2 , and CH 4 has several applications, including CO 2 capture, methane, and hydrogen storage. The performance ultimately depends on the adsorbent design. Herein, we report a comparative assessment of a Cu-metal−organic framework (MOF) (HKUST-1) by conventional hydrothermal synthesis and its modified analogues, HKUST-N with NH 4 OH and HKUST-Ca with Ca(NO 3 ) 2 , for CO 2 , CH 4 , and H 2 adsorption. The materials showed high CO 2 (12 mol/Kg), CH 4 (2.5−4 mol/Kg), and H 2 (0.4−0.8 mol/Kg) capacities at 50 bar. Owing to different synthesis strategies, the differences in surface area, pore size distribution, morphology, and the presence of calcium species in HKUST-Ca considerably impacted CH 4 and H 2 adsorption, leading to considerable differences in selectivities for various gas mixtures. This work establishes a clear correlation of subtle modifications in synthesis strategies of the MOF HKUST-1 on its morphological characteristics and CO 2 , CH 4 , and H 2 adsorption performance.

“…Also, H 2 reactivity to calcite is weak and, thus, has low adsorption. Similarly, Abid et al reported low adsorption of H 2 (0.056 mol/kg) in shales; however, adding humic acid increased the adsorption to 0.3 mol/kg.…”

Underground hydrogen storage (UHS) is a promising solution to meet the increase in energy supply and demand while supporting the energy transition to net-zero carbon. The successful implementation of UHS requires careful assessment of several scientific aspects, among them evaluating the cement stability and wellbore integrity to ensure safe storage and production of hydrogen. Few studies have evaluated the geochemical reactivity of cement to hydrogen; however, more studies are needed to explore the role of hydrogen adsorption and diffusivity behavior with cement and address the associated wellbore integrity issues. This minireview presents the state-of-the-art advancement in evaluating the impact of hydrogen on cement wellbore stability from various aspects, including hydrogen/ cement interactions, hydrogen adsorption and diffusivity, current methodologies, experimental setups, and the role of cement additives and cushion gases. This minireview provides a general comparison between UHS and other gas storage applications and mainly aims to bridge the knowledge gap by providing insights for practical implementations, challenges, and future directions relevant to wellbore integrity. Although most of the reviewed studies reported a low impact of hydrogen injection on cement stability, the successful implementation of UHS requires further assessment as various technical and non-technical factors and mechanisms are involved. Systematic scientific studies should be performed in the future, which will assist in overcoming the existing challenges and reducing the uncertainty associated with wellbore integrity during UHS.

“…The authors utilized a magnetic measurement technique, with the findings revealing that the basalt rock sample used is ferromagnetic and possesses a high dielectric constant. To date, however, the focus has primarily been on the petrophysical characteristics and storage capacity of the chosen storage locations around the world. , In a report, ranking the storage sites in various nations, this is the situation. More specifically, the electrokinetic properties of the basaltic rocks (igneous rocks), which regulate properties like disjoining pressure, wetting state, surface adsorption, and precipitation potential of materials, have not attracted as much attention as the basaltic rocks’ mineralogical composition.…”

The reduction of carbon footprints is one of the steps being taken as the world looks for a solution to the difficulties caused by climate change. This will be accomplished by developing technologies that both consume and emit less carbon dioxide into the atmosphere. Other methods include mineralization or bulk storage of the captured gases in subsurface reservoirs. Mineralization involves the interaction of cation-rich rocks or fluids with carbonated water to form precipitates that ensure the safe disposal of CO2 that has been captured. To assess the viability of this route, numerous initiatives have been made as well as a few experimental projects. Understanding of the electrokinetic property of igneous rocks, which governs characteristics like wetting conditions and susceptibility to release cations, is, however, rare in the literature. Thus, to shed light on the electrokinetic behavior and colloidal stability of igneous rocks, this research has employed electrophoresis. This research revealed that igneous rocks are mainly negatively charged in both freshwater and saltwater environments. On the other hand, igneous rocks’ magnesium ion content significantly affects how they are charged, occasionally flipping the charge to positive and shifting the solution state from acidic to alkaline. This would have an even greater effect on the mineralization process and shorten the time needed for the reaction between igneous and CO2-rich fluids. This is inferred by the fact that the highest dissolution of metal cations is known to occur at pH values of 3 and 4. Furthermore, samples with a low magnesium content have stable colloidal stability, whereas samples with a high magnesium content are colloidally unstable. The samples’ colloidal stability also has a significant impact on how easily the cations needed for mineralization are released.
