“…Hence, the results of these modeling studies on hydrogen storage in depleted reservoirs (Hagemann et al, 2016;Hemme and Van Berk, 2018;Hassannayebi et al, 2019;Veshareh et al, 2022) considering microbial kinetic control on the redox reactions using hydrogen as electron donor are in line with the results of our simulations applied to the gas composition evolution at Lobodice town gas storage. Namely, hydrogen can be reactive when catalyzed by microbial activity, leading to the formation of methane and hydrogen sulfide.…”

“…Only few studies have simulated the reactivity of hydrogen in UHS in porous media by considering the microbial catalysis and limitation of the redox reactions using hydrogen as electron donor through a kinetic control on these reactions (Hagemann et al, 2016;Hemme and Van Berk, 2018;Hassannayebi et al, 2019;Veshareh et al, 2022).

“…This study suggested that the reactions of hydrogen with minerals can only be relevant over time scales longer than the storage operations and that their estimation is strongly related to the uncertainty on the kinetic rates. Simulations by Veshareh et al (2022) were dedicated to the evaluation of hydrogen reactivity if stored in Danish North Sea chalk reservoirs. Methanogenesis, sulfatereduction and acetogenesis reactions were both controlled by kinetics, using a Monod-type equation.…”

Underground Hydrogen storage (UHS) is a promising technology for safe storage of large quantities of hydrogen, in daily to seasonal cycles depending on the consumption requirements. The development of UHS requires anticipating hydrogen behavior to prevent any unexpected economic or environmental impact. An open question is the hydrogen reactivity in underground porous media storages. Indeed, there is no consensus on the effects or lack of geochemical reactions in UHS operations because of the strong coupling with the activity of microbes using hydrogen as electron donor during anaerobic reduction reactions. In this work, we apply different geochemical models to abiotic conditions or including the catalytic effect of bacterial activity in methanogenesis, acetogenesis and sulfate-reduction reactions. The models are applied to Lobodice town gas storage (Czech Republic), where a conversion of hydrogen to methane was measured during seasonal gas storage. Under abiotic conditions, no reaction is simulated. When the classical thermodynamic approach for aqueous redox reactions is applied, the simulated reactivity of hydrogen is too high. The proper way to simulate hydrogen reactivity must include a description of the kinetics of the aqueous redox reactions. Two models are applied to simulate the reactions of hydrogen observed at Lobodice gas storage. One modeling the microbial activity by applying energy threshold limitations and another where microbial activity follows a Monod-type rate law. After successfully calibrating the bio-geochemical models for hydrogen reactivity on existing gas storage data and constraining the conditions where microbial activity will inhibit or enhance hydrogen reactivity, we now have a higher confidence in assessing the hydrogen reactivity in future UHS in aquifers or depleted reservoirs.

“…It is unclear whether or how these microbial H 2 oxidation processes will occur in salt caverns and if so, to what extent. Some modelling approaches have indicated potential H 2 S formation 21,22 . However, these models are based on kinetic rates of general sulphatereducers, and it can be assumed that a) growth and consumption is different with H 2 as an electron donor, and b) that extremely halophilic strains show different rates due to their energy expenditures on osmoregulation.…”

Salt caverns have been successfully used for natural gas storage globally since the 1940s and are now under consideration for hydrogen (H2) storage, which is needed in large quantities for the Green Shift. Salt caverns are not sterile, and H2 is a ubiquitous electron donor for microorganisms. This could entail that the injected H2 will be microbially consumed, leading to a volumetric loss and potential production of toxic H2S. However, the extent and rates of this microbial H2 consumption under high-saline cavern conditions are not yet understood. To investigate microbial consumption rates, we cultured the halophilic sulphate-reducing bacteria Desulfohalobium retbaense and the halophilic methanogen Methanocalcus halotolerans under different H2 partial pressures. Both strains consumed H2, but consumption rates slowed down significantly over time. The activity loss correlated with a significant pH increase (up to pH 9) in the media due to intense proton- and bicarbonate consumption. In the case of sulphate-reduction, this pH increase led to dissolution of all produced H2S in the liquid phase. We compared these observations to an original brine retrieved from a salt cavern located in Northern Germany, which was incubated with 100% H2 over several months. We again observed a H2 loss (up to 12%) with a concurrent increase in pH up to 8.5 especially when additional nutrients were added to the brine. Our results clearly show that sulphate-reducing microbes present in salt caverns will consume H2, which will be accompanied by a significant pH increase, resulting in reduced activity over time. This potentially self-limiting process of pH increase during sulphate-reduction will be advantageous for H2 storage in low-buffering environments like salt caverns.

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.
