This paper presents an in-depth investigation of the biogeochemical modeling approaches applied to underground hydrogen storage. It delves into intricate dynamics in subsurface, focusing on small (pore-lab scale) and reservoir-scale models, highlighting importance capturing microbial, geochemical, fluid flow dynamic interactions porous media simulate storage performance accurately. Small-scale models offer detailed insights localized phenomena, such as microbial consumption mineral reactions, can be verified calibrated against laboratory data. Conversely, large-scale are essential assess feasibility a project forecast performance, but cannot proven by real data yet. work addresses challenge transitioning from fine-scale reservoir integrating spatial heterogeneity long-term while retaining complexity. Through use several simulation tools, like PHREEQC, Comsol, DuMuX, Eclipse, CMG-GEM, others, this study explores how evolving incorporate multiphysics processes biochemical feedback loops, which for predicting retention, flow, potential risks. The findings highlight strengths limitations current techniques suggest workflow exploiting at best existing capabilities developing support appraisal management.
