At the CLNB 2025 (10th) New Energy Industry Chain Expo - Hydrogen Energy Industry Development Forum, hosted by SMM Information & Technology Co. , Ltd. (SMM), Zhang Yuxiang, Co-founder and Director of Ai Hydrogen Technology (Suzhou) Co. , Ltd. , presented on the topic "Current Status and Prospects of Pure Magnesium-Based Solid-State Hydrogen Storage. " He addressed key challenges in hydrogen energy, notably storage and transportation bottlenecks. Upstream resources remain abundant, with global hydrogen production projected to reach 500-800 million metric tons by 2050. On the downstream side, demand is strong across hydrogen storage and transportation, chemical transportation, and electromechanical applications for daily health. Overview: Solid-state hydrogen storage provides solutions to the challenges of achieving high-density hydrogen storage safely. Among these, magnesium-based hydrogen storage materials offer significant practical advantages. Principles and Benefits of Magnesium-Based Hydrogen Storage: Hydrogen Storage Mechanism: This process involves a chemical reaction where hydrogen is stored in magnesium metal as metal hydrides.

Upon heating, these hydrides decompose, releasing hydrogen and reverting to magnesium metal, enabling efficient hydrogen recycling with excellent reversibility. Technical Benefits: Magnesium-based materials boast a high energy density, with a theoretical hydrogen storage capacity of 7. 6%, exceeding that of many other storage materials. This makes them ideal for large-scale hydrogen storage and transport, portable devices, and mobile uses. They demonstrate exceptional cycle stability, maintaining high hydrogen storage efficiency through multiple charge-discharge cycles, which extends lifespan and lowers replacement costs. Environmental Advantages: Magnesium extraction and processing are relatively eco-friendly, producing no harmful byproducts during hydrogen storage. The ability to reconvert released hydrogen back into magnesium metal means zero waste generation, supporting sustainable hydrogen energy development. Directions for Performance Enhancement: Efforts focus on material modification to tackle challenges such as high hydrogen absorption/desorption temperatures and slow kinetics. Industrial Applications of Magnesium-Based Hydrogen Storage: Ai Hydrogen’s magnesium-based hydrogen storage products include solid magnesium hydride, which at standard room temperature and pressure exhibits the highest reversible hydrogen absorption rate among materials, at 7. 6% by mass. Methods for Hydrogen Release from Magnesium-Based Materials: - Pyrolysis: Heating the material releases hydrogen under normal pressure, stored in hydrogen bottles. - Hydrolysis: Adding warm water to magnesium hydride triggers a hydration reaction that releases hydrogen directly. Application Markets: - Primary: Hydrogen storage and transportation. - Secondary: Electromechanical devices, industrial sectors, transportation, and daily health products. Sectors Benefiting: - Transportation. - Electromechanical products, including hydrogen power supply units based on solid magnesium hydride, available in capacities from 100W to 5KW. - Fine chemical products such as hydrogen-enriched candies, hydrogen-rich water masks, hydrogen-infused soaps, and hydrogen cleansing balls. Due to its strong reducibility, magnesium hydride releases hydrogen by pyrolysis or hydrolysis and finds broad applications in daily and health-related products.
