摘要：

Hydrogen storage is essential for balancing supply and demand in renewable-integrated hydrogen systems. We study a coordinated production-storage-delivery scheme that jointly operates high-purity surface tanks (fast buffer) and underground salt-cavern storage (seasonal reserve) under a unified control policy with a modest gridpower set-point for the electrolyzer. A year-long (8,760 h) multi-scenario simulation spanning grid-participation levels and storage capacities shows that grid participation sharply reduces the storage capacity required for interruption-free pipeline delivery and eases equipment duty. With a 20 % grid set-point, the minimum crudehydrogen capacity needed to avoid any pipeline curtailment falls from 25,000 kg (off-grid) to 7,000 kg, while the crude-side compressor peak flow decreases from 83.9 to 48.1 kg & sdot;h- 1; cavern cycling naturally remains at about one injection-withdrawal per day, consistent with engineering constraints. When crude storage is undersized, curtailments and compressor stress rise markedly; by contrast, high-purity tank limits mainly constrain sales without interrupting transport. These results translate into actionable sizing rules and operating set-points for hydrogen hubs, pipeline-blending networks, and industrial clusters, enabling year-round, reliable hydrogen supply with smaller storage builds and improved lifecycle reliability.
