The paper reviews the advancements and prospects of solid-state hydrogen storage technology in China, focusing on material systems, thermodynamic mechanisms, and system integration. It assesses the market potential across four key application scenarios: on-board hydrogen storage, hydrogen refueling stations, backup power supplies, and power grid peak shaving. Despite current challenges in cost and performance, the technology offers high safety, energy density, and potential cost savings, making it promising for new energy vehicles and distributed energy fields. Breakthroughs in materials like magnesium-based and vanadium-based systems, along with improved standards and innovation platforms, are expected to make solid-state hydrogen storage mainstream within 10–15 years, with a market scale exceeding USD 14.3 billion. The paper recommends increased investment in basic research, focused efforts on core technologies, and streamlined industry chains to accelerate China's solid-state hydrogen storage industry.The paper reviews the advancements and prospects of solid-state hydrogen storage technology in China, focusing on material systems, thermodynamic mechanisms, and system integration.
