With the issue of energy shortages becoming increasingly serious, need to shift sustainable and clean sources has become urgent. However, due intermittent nature most renewable sources, developing underground hydrogen storage (UHS) systems as backup solutions offers a promising solution. The thick regionally extensive salt deposits in Unit B Southern Ontario, Canada, have demonstrated significant potential for supporting such systems. Based on stratigraphy statistics unit B, this study investigates feasibility stability caverns, focusing effects cavern shape, geometric parameters, operating pressures. Three shapes—cylindrical, cone-shaped, ellipsoid-shaped—were analyzed using numerical simulations. Results indicate that cylindrical caverns with diameter-to-height ratio 1.5 provide best balance between capacity structural stability, while ellipsoid-shaped offer reduced stress concentration but less space, posing practical challenges during leaching. results also optimal pressure range maintaining minimizing leakage lies 0.4 0.7 times vertical situ stress. Higher pressures increase lead greater stress, displacements, risks, lower leads internal extrusion tendency walls. Additionally, rate drops maximum working pressure, yet total mass keeps growing trend.
