Talk Tilte: Research on High-Efficiency Hydrogen Production and Storage Technology Based on Metal Hydrides
Abstract:
EAs a widely sourced, clean, and efficient secondary energy carrier, hydrogen is regarded as a key enabler for achieving carbon neutrality. However, its large-scale application still faces two core challenges: efficient, safe storage/transportation and controllable on-demand release. Metal hydrides, with their high volumetric hydrogen storage density, excellent safety, and reversible reaction characteristics, demonstrate significant potential in solid-state hydrogen storage and chemical hydride-based hydrogen production. This presentation focuses on two typical metal hydrides—reversible hydrogen storage materials represented by magnesium-based hydrides, and hydrolysis-based hydrogen production materials represented by sodium borohydride. It systematically reports our series of research work on material modification, reaction mechanisms, and system applications. Through material innovation and mechanistic investigation, progress has been made in both the MgH₂-based high-capacity reversible hydrogen storage system and the NaBH₄-based portable controllable hydrogen production system. Future work will focus on further optimizing the comprehensive performance of materials, deepening the understanding of multi-scale reaction mechanisms, and advancing the design and demonstration of integrated systems for specific application scenarios, thereby providing practical solutions for the diversified development of hydrogen energy technologies.
