| 英文摘要 | The safe and large-scale storage of hydrogen is a key enabler for the commercial development of the hydrogen industry. This study analyses the impact of varying cyclic internal gas pressure (IGP) magnitudes on the stability of salt cavern hydrogen storage (SCHS), as well as the influence of diverse salt rock permeability and porosity conditions on the tightness of SCHS. Subsequently, a novel safety evaluation system for SCHS has been devised and its safety has been assessed using the matter-element extension method. The findings indicate that: (1) The IGP of hydrogen stored in the two-butted-well horizontal (TWH) salt cavern is well stabilised at 8-18 MPa. The volume shrinkage and displacement are 9.3 % and 4.36 m, respectively, both of which are below the critical value. (2) It has been determined that when the permeability of the salt rock is 1e- 19 m2, the leakage percentage after 30 years of operation is 34.1 %, which exceeds the critical value. The salt cavern in question is not suitable for storing hydrogen gas due to its poor tightness. (3) When the permeability of the salt rock in this TWH salt cavern is less than 1e- 21 m2, the safety level is I, indicating that the safety of SCHS is very safe. This study presents a novel system for the assessment of the safety of SCHS, together with theoretical guidance for the feasibility assessment and site selection for SCHS. |
