These approaches, while functional, presented significant safety concerns and energy inefficiencies that limited widespread adoption.
The 1970s energy crisis marked a pivotal moment in hydrogen storage research, catalyzing interest in alternative storage methods. This period saw the emergence of metal hydrides as promising storage materials, with scientists discovering that certain metals could absorb hydrogen atoms within their crystal lattice structures, enabling storage at lower pressures and ambient temperatures.
By the 1990s, research expanded to include complex hydrides and chemical hydrogen storage materials, offering higher theoretical storage capacities. The early 2000s witnessed a paradigm shift with the introduction of nanomaterials and engineered structures, including carbon nanotubes, metal-organic frameworks (MOFs), and covalent organic frameworks (COFs), which demonstrated enhanced hydrogen adsorption properties.
Current research objectives center on developing materials that meet the U.S. Department of Energy's technical targets for onboard hydrogen storage systems: 6.5 wt% system gravimetric capacity and 50 g/L volumetric capacity, with operating temperatures between -40°C and 60°C and refueling times under 3 minutes. These benchmarks represent the minimum performance requirements for competitive hydrogen-powered vehicles.
The technological trajectory indicates several promising research directions. Advanced metal hydrides with improved kinetics and reduced operating temperatures represent one avenue, while nanoporous materials with optimized pore structures and binding energies offer another. Liquid organic hydrogen carriers (LOHCs) are gaining attention for their potential in stationary applications and hydrogen transport infrastructure.
Patent landscapes reveal concentrated innovation clusters in solid-state storage materials, particularly in reversible metal hydrides and composite materials that combine physical and chemical storage mechanisms.
