Development and Application of High-Performance Solid-State Hydrogen Storage Materials

This document presents the development and application of high-performance solid-state hydrogen storage materials for hydrogen energy storage, authored by Zou Jianxin from Shanghai Jiao Tong University. It begins with the research background, emphasizing the need for low-carbon energy and green development due to fossil fuel depletion and environmental pollution. Hydrogen energy is highlighted as a key carrier for achieving dual carbon goals, with efficient and safe hydrogen storage being a critical bottleneck. The document reviews the history of solid hydrogen storage materials, from early discoveries like ZrNiH3 to modern MOFs and magnesium-based materials. It details the performance characteristics of various types, including MOF-808-mc, titanium-based alloys, and magnesium-based materials, focusing on hydrogen storage density, absorption/desorption kinetics, cycle stability, and thermal conductivity. Applications include a multi-bottle titanium-based hydrogen storage system with optimized weight and performance. The conclusion underscores the advantages of magnesium-based materials, such as high hydrogen storage density and abundant resources, positioning them as promising for industrial applications.
