Abstract With the continuous advancement of global carbon neutrality goals, hydrogen, as a clean and efficient energy carrier, is increasingly recognized as a critical enabler for energy transition and emission reduction. However, mismatches between hydrogen supply and demand may arise due to seasonal fluctuations and intermittent renewable generation, underscoring the essential role of effective storage. Depleted shale gas reservoirs, due to their substantial available storage capacity and unique geological characteristics, are regarded as promising candidates for large-scale underground hydrogen storage (UHS). Despite this potential, a comprehensive understanding of UHS in such reservoirs remains limited. To address this gap, this review provides a systematic synthesis of recent advances in geochemical and biochemical reactions, surface and interfacial phenomena, adsorption–diffusion processes, and reservoir-scale simulations relevant to UHS in depleted shale gas reservoirs. Drawing on these interdisciplinary insights, the technical, safety, and economic challenges associated with UHS in depleted shale gas reservoirs are examined. Finally, potential future research directions in areas such as experimental studies, numerical simulations, and supporting technologies are highlighted. This review delivers the first systematic perspective on H₂-brine-shale interactions and multi-field coupling processes in UHS within depleted shale gas reservoirs, offering essential guidance for...
