Summary Metal‐organic frameworks (MOF) have emerged as a promising material for green engineering applications due to their attractive properties. But the successful implementation of this material in the field of fuel cell technologies is still a challenge. Researchers have reported more than 50% reduction in experimental bulk density of compacted MOFs relatively to their theoretical crystal density. This has resulted in reduction of gravimetric and volumetric H 2 storage capacities of MOFs. Significant experimental research should be directed toward the consolidation of MOFs to meet (6.5 wt%; 50 g/L) 2025 DoE target for onboard H 2 storage systems. We present an overview of green engineering materials for hydrogen storage systems. The review also summarizes recent advancement in the consolidation of MOFs as absorbents for hydrogen storage. The influence of densification techniques on MOFs textural properties, mechanical stability were discussed. Hydrogen storage capacity of both powder and densified high‐performance MOFs were presented.
