A research team at the Korea Institute of Materials Science has developed the world's first solid-state hydrogen storage material, the magnesium-nickel-tin alloy (Mg-20Ni-Sn). This innovative alloy securely stores and transports hydrogen within its metal structure, eliminating the need for high-pressure tanks or cryogenic systems. The technology addresses challenges associated with conventional storage methods, such as high explosion risks, excessive energy consumption, and natural boil-off losses. By chemically bonding hydrogen with metal and enabling its release when needed, this method ensures long-term storage and transportation without the risk of explosion. The magnesium-nickel-tin alloy combines high-density magnesium phases with magnesium-nickel phases in a layered structure, improving hydrogen storage performance significantly. The addition of tin refines the grain structure, enhancing reactivity and leading to a more than threefold enhancement in performance compared to traditional materials. The new technology allows for the transport of hydrogen via standard vehicles, cutting transportation costs and simplifying the manufacturing process. The research team's method uses casting to produce bulk alloy, machined into thin metal chips for efficient reactions. This approach reduces manufacturing costs and allows for mass production. Collaborations with industry partners have led to the development of induction-heated storage vessels and real-time monitoring systems, further enhancing the impact of the research. Dr. Young-Min Kim, the Principal Researcher, highlighted the significance of this technology in enabling the safe and cost-effective transportation of hydrogen without specialized equipment. The team aims to expand its applications in various sectors, including power plants, electric vehicles, and energy storage systems, by integrating it with hydrogen from renewable and nuclear sources.
