Organic supramolecular crystals with high hydrogen storage performance could enhance fuel-cell vehicle efficiency
Briefly

Hydrogen, while a zero-emission fuel with high gravimetric energy density, faces challenges in storage and transport due to its low volumetric density, requiring advancements in storage technology.
To facilitate the widespread use of hydrogen-powered FCVs, the US DOE has set storage targets: a gravimetric capacity of 6.5 wt% and a volumetric capacity of 50 g L ‒1 for the material.
Developing porous adsorbent materials like MOFs and COFs is a promising strategy to achieve hydrogen storage targets, aiming for low-pressure storage systems under 100 bar.
While advancements have been made in gravimetric storage capacities, many materials still struggle with volumetric capacities, crucial for efficiently integrating hydrogen storage into vehicle designs.
