This sub-topic studies sorption/desorption rates, diffusion barriers, and additives to enhance kinetics in storage materials. Researchers employ modeling and in-situ characterization for rapid refueling.
Why It Matters
Hydrogen storage materials enable mobile applications like fuel cell vehicles by addressing challenges in capacity and release kinetics, as detailed in 'Hydrogen-storage materials for mobile applications' (2001) by Schlapbach and Züttel. Metal hydride materials support solid-state storage with high volumetric density, reviewed in 'Metal hydride materials for solid hydrogen storage: A review' (2007) by Sakintuna et al., which covers systems like LaNi5H6 achieving up to 1.4 wt% hydrogen uptake. Catalysts such as MoS2 nanoparticles reduce reliance on platinum for hydrogen evolution, with 'Biomimetic Hydrogen Evolution: MoS2 Nanoparticles as Catalyst for Hydrogen Evolution' (2005) by Hinnemann et al. demonstrating turnover frequencies comparable to Pt at low overpotentials. These advancements impact energy storage in batteries and supercapacitors, per 'Advanced Materials for Energy Storage' (2010) by Liu et al., and contribute to global decarbonization strategies outlined in 'The role of hydrogen and fuel cells in the global energy system' (2018) by Staffell et al.
