The World¡äs Largest Pilot Plant for Solid-State Hydrogen Storage Materials Starts Operation
2025-5-27
Recently, after the 150-ton/year magnesium hydride pilot production line of Yulin Zhongke Innovation Institute of Clean Energy was put into operation in Yulin, Shaanxi, it has transitioned to stable operation following defect elimination and optimization. This is China¡äs first hundred-ton-level magnesium hydride hydrogen storage material pilot production line with independent intellectual property rights, and it is the largest in the world. This milestone signifies a major breakthrough in China¡äs hydrogen energy storage and transportation technology as well as key material preparation.
The project has a total investment of 50 million yuan, and the production facilities include magnesium powder preparation, magnesium hydride synthesis, automatic packaging units, etc. In January this year, the pilot plant production line successfully started operation with one-time feeding, producing the first batch of qualified products, and achieving unmanned on-site monitoring and automated operation. The prepared magnesium hydride materials have two types of mass hydrogen storage densities: 6.5wt% and 7.2wt%, and can produce powdery, granular, and block-shaped magnesium hydride products according to requirements. At present, the process package for the 10,000-ton magnesium hydride project is being compiled, striving to land the industrial demonstration project in Yulin, which will promote the comprehensive utilization of abundant industrial by-product hydrogen and the transformation and upgrading of the metal magnesium industry in the local area.
It is understood that solid-state hydrogen storage is an emerging technology in the hydrogen storage sector. Compared with high-pressure gas energy storage and low-temperature liquid hydrogen storage, it features high safety, high volumetric hydrogen storage density, and convenient transportation. Among them, magnesium hydride materials are safe, environmentally friendly, and recyclable, making them a hydrogen storage material with extremely promising applications. Compared with other metal-based hydrogen storage materials, magnesium-based solid-state hydrogen storage materials have obvious advantages in terms of hydrogen storage weight density, which is 5 times that of traditional high-pressure gaseous hydrogen storage. They can be safely transported under normal temperature and pressure, providing a high-safety, high-efficiency, and low-cost hydrogen energy storage and transportation solution.
