A coupled thermo-hydro-bio-chemical model for underground hydrogen storage in aquifers: new insights into biochemical effects
Underground hydrogen storage in aquifers (UHSA) is a promising approach for large-scale, cyclical hydrogen storage. However, indigenous hydrogenotrophic microorganisms may utilize hydrogen for biochemical reactions, potentially causing issues such as pore clogging and hydrogen loss. These microbial activities are further influenced by multi-physical fields such as fluid flow and temperature. In this study, we developed a coupled thermo-hydro-bio-chemical model for UHSA. Numerical simulation of a base-case scenario was conducted to investigate the spatiotemporal distribution of microorganisms, evolution of reservoir porosity, and hydrogen recovery performance. In addition, we analyzed the impact of various hydrogen injection strategies on biochemical effects. Our results indicate that microbial populations generally exhibit a growth-then-decay trend, and convective flow during the production stage can reduce microbial concentrations. Injecting low-temperature hydrogen helps suppress the formation of high-density microbial communities. Microorganisms are accumulated in the low-temperature zone during the production stage, resulting in substantial microbial decay which is favorable for hydrogen storage. Porosity evolution during the hydrogen storage process is primarily governed by microbial adsorption in the early stage and by mineral dissolution and precipitation in the later stage, showing a slight increase followed by a decrease. Nonetheless, the overall variation in porosity is negligible, exerting minimal influence on the flow behavior. Biogeochemical reactions lead to a 9.53% hydrogen loss and a 5% reduction in recovery efficiency. Compared to other injection strategies, slow and pulsed hydrogen injection induces a weaker microbial response. These findings enhance understanding of the biochemical impacts in UHSA and provide technical insights for practical applications.
