Abstract: Subsurface energy storage, encompassing geological CO₂ sequestration, underground hydrogen storage (UHS), aquifer thermal energy storage (ATES), and compressed-air energy storage (CAES), is expanding rapidly as decarbonization infrastructure, and much of it is sited in or beneath saline formations that directly overlie or adjoin freshwater aquifers. This review synthesizes evidence on an under-recognized consequence of this expansion: storageinduced disturbance of the freshwater–saline interface and consequent salinization risk to overlying underground sources of drinking water (USDW).
