Hydrogen energy storage is a cornerstone of the transition toward sustainable and renewable energy systems, requiring innovative solutions for efficiency and scalability. This research explored the application of Triply Periodic Minimal Surfaces (TPMS) structures, focusing on topology optimization to enhance mechanical integrity, internal volume and material efficiency under high loading conditions. For this study, a gyroid-based TPMS structure was integrated into a storage container geometry and optimized using the Solid Isotropic Material with Penalization (SIMP) method under displacement restraint, internal pressure, and external compressive loading. Both non-optimized and optimized structures were then put through static analysis to evaluate the structural response. The optimization process demonstrated stable convergence across all loading cases, resulting in redistributed material aligned with critical load-paths, with post-optimization analysis indicating increased structural compliance and localized stress concentrations, with a modest increase in internal volume. The results display that topology optimization enhances structural efficiency primarily through material redistribution rather than uniform material reduction, highlighting its potential for improving TPMS-based hydrogen storage structures.
