Hydrogen is a pivotal energy carrier for achieving sustainability and stability, but safe efficient geological underground hydrogen storage (UHS) critical its large-scale application. This study investigates the impacts of geochemical biochemical reactions on UHS, addressing challenges that threaten efficiency safety. Geochemical in saline aquifers, particularly generation sulfide (H2S), were analyzed using advanced compositional modeling calibrated with experimental kinetic data. The results indicate have minimal effect consumption. However, by year 10 operations, H2S levels could reach 12–13 ppm, necessitating desulfurization to maintain performance also examines methanogenesis reaction, where microorganisms consume carbon dioxide produce methane. Numerical simulations reveal microbial activity under suitable conditions can reduce situ volume up 50%, presenting hurdle UHS feasibility. These findings highlight necessity conducting analyses reservoir brines during screening phase mitigate losses. novelty this work lies comprehensive field-scale analysis impurity-induced their implications storage. By integrating parameters derived from data computational modeling, uncovers mechanisms driving these highlights impact efficiency, offering detailed perspective, provide framework advancing future projects ensuring practical viability.
