“…However, the presence of H 2 alone had minimal to no effect on the static storage of gas, because class G cement samples exposed to both hydrogen and nitrogen showed similar changes in their porosity and permeability values. Similarly, Al-Yaseri et al 25 reported insignificant alteration in the cement properties, and no major changes in cement mineralogy were observed; however, the CT scan porosity of the samples was reduced by approximately 8%, with a slight increase in the cement weight…”

“…24 For instance, depleted hydrocarbon reservoirs were found as effective storage sites for natural gas and CO 2 , and they can be effective storage sites for hydrogen as well. 25 However, as a result of the difference in physical/chemical properties of H 2 (e.g., molecular weight, density, viscosity, and diffusivity) compared to other gases, more studies are needed to understand the nature of H 2 reactivity in geological formations. Figure 1 presents a comparison of the physical properties of hydrogen to those of carbon dioxide and methane.…”

“…One of the critical issues with UHS in depleted hydrocarbon reservoirs is the assessment of wellbore and cement integrity, which plays a vital role during the injection/withdrawal of hydrogen. 25 It is believed that wellbore cement can prevent leakage; however, that is debatable, because cement is a porous material that is subjected to fractures and channels development in the long term. 27 Also, the complexity of the casing/ cement/formation interaction with hydrogen raises the potential for gas leakage.…”

“…Similarly, during H 2 injection, the possible degradation of cement integrity is not fully understood, and only limited studies have been performed. 25,49 Various factors can contribute to cement degradation during UHS, such as the presence of CO 2 in the brine/formation, 30 the generation of hydrogen sulfide, 50 and the existence of fractures in the cement sheath or microbial activities that lead to casing corrosion. 51 Therefore, addressing and understanding the associated issues of wellbore integrity during UHS are crucial for successful long-term containment/utilization of hydrogen as an energy source.…”

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.

“…This behavior can cause various minerals’ precipitation such as quartz, carbonates, and clays. Despite the low contents of carbonate and clay minerals generally in basalt, however, the dissolution of carbonate and clay minerals might occur as well due to the increase in pH with hydrogen injection (generally above 10 ,, ). Based on the simulation work of Zeng et al, in the long-term fluid–rock interactions, calcite can react with hydrogen ions and the brine formation and generate bicarbonate (HCO 3 ), Ca 2+ , and aqueous CO 2 .…”

Hydrogen geo-storage is a promising technology to achieve net-zero carbon emissions. Basaltic rocks have attracted limited attention, and only limited knowledge of the suitability of the basaltic formations for large-scale hydrogen storage is available. The complex in situ geochemical reaction of basalt−hydrogen is a key factor in evaluating the suitability of basalt for hydrogen storage. This paper investigates the geochemical interactions of hydrogen−basalt− water and evaluates the impact on basalt's physical properties. Basalt samples collected from the CarbFix site in Iceland are treated with hydrogen−water for 108 days under 9.65 MPa at 348 K, and various analytical methods are employed. The results show minor dissolution of plagioclase minerals after hydrogen treatment due to the redox reactions of hydrogen. However, this dissolution behavior might contribute to the precipitation of calcium on the basalt surface. Images obtained from scanning electron microscopy reveal that only the filling of the cracks was removed after the treatment with no obvious crack growth, which resulted in a minor increase in the pores (4%). Contact angle measurements show that the surface wettability remains water-wet after the treatment. A blank nitrogen− DI water test is performed, to reveal the potential reactions between water and basalt, indicating that only minor changes exist. We conclude that the reactivity of basaltic minerals to hydrogen−water injection is low; thus, the suitability of basalt for hydrogen storage is promising. This work can be a suitable experimental framework to assist in evaluating the hydrogen reactivity to basaltic rocks and assessing the suitability for UHS.
