Hydrogen has emerged as a critical energy carrier for achieving global decarbonization and supporting sustainable future. This review explores key advancements in hydrogen production technologies, including electrolysis, biomass gasification, thermochemical processes, alongside innovations storage methods like metal hydrides liquid organic carriers (LOHCs). Despite its promise, challenges such high costs, scalability issues, safety concerns persist. Biomass gasification stands out dual benefits of waste management carbon neutrality yet hurdles feedstock variability efficiency need further attention. also identifies opportunities improvement, developing cost-effective catalysts hybrid systems, while emphasizing future research on improving tackling bottlenecks. By addressing these challenges, can play central role the transition to cleaner systems.

This study investigates the electrochemical characteristics of nanostructured LaNi5 intermetallic synthesized via sol-gel method for application as an anode material in nickel-metal hydride (Ni-MH) batteries. A comparison with a commercial counterpart produced by fusion synthesis mechanical grinding revealed that material, primary particle sizes 300–700 nm, exhibits significantly improved kinetic properties, including reduced charge transfer resistance and more efficient mass transport. The demonstrates rapid activation, reaching maximum capacity 180 mAh/g 5th cycle, although degradation to 130 is observed 50th cycle. In contrast, sample slow gradual increase 190 followed stabilization. discrepancy between enhanced properties cycle stability presents promising direction optimizing materials Ni-MH
