Implication

Systematic review reveals substantial reaction time reductions using hybrid thermal management in metal hydride reactors, highlighting trade-offs with storage capacity.

Key Points

To systematically evaluate the evolution and effectiveness of metal hydride reactor designs integrated with phase change materials and hybrid thermal management systems.
Systematic review synthesizing numerical (2D and 3D) simulations and experimental studies.
Comparative analysis of passive interventions (metal foam, nano-additives, fins) and active heat transfer fluid mechanisms across various reactor geometries.
Optimized 30-fin copper configurations and metallic foams achieved peak reaction time reductions of 97.3% and 84%, respectively, while advanced basic geometries reached up to an 81.5% reduction.
Active heat transfer fluid systems demonstrated thermal management effectiveness ranging from 33.5% to 94% across different operational designs.
