World's First Ton-Scale Magnesium-Based Solid-State Hydrogen Storage and Transportation System Successfully Demonstrated in Hydrogen Metallurgy Scenario

Recently, the world's first engineering demonstration project targeting hydrogen metallurgy scenarios, equipped with a ton-level magnesium-based solid-state hydrogen storage and transportation system provided by Hydrogen Maple, has been successfully conducted. This marks a significant breakthrough in China's application of hydrogen energy storage and transportation and hydrogen metallurgy, holding milestone significance. Through technological innovation and scenario coupling, the project has established a safe, efficient, and economically viable hydrogen supply solution for hydrogen metallurgy, laying a critical foundation for the large-scale application of hydrogen energy in heavy industries.

It is reported that this project is developed under the national key R&D plan. The demonstration project is equipped with a steel mill waste heat management system, including key equipment such as nitrogen gas manifold and hydrogen release valve groups, enabling safe hydrogen transportation and heat exchange under low pressure. It fully utilizes steel mill waste heat resources to enhance energy utilization efficiency. Meanwhile, the project has designed a solid-state hydrogen storage control and safety monitoring system, which can monitor key parameters such as hydrogen pipeline leakage, pressure, and temperature in real time. It also employs AI video recognition to detect color changes in hydrogen-sensitive tapes for intelligent early warning, effectively ensuring continuous system operation without major accidents. Currently, the system has achieved stable and efficient operation, providing a reliable practical solution for the application of solid-state hydrogen storage technology in industrial scenarios.

Hydrogen metallurgy, as a crucial application scenario of hydrogen energy in the industrial sector, is a key technological direction for promoting the low-carbon transformation of traditional high-carbon metallurgy industries. It has an urgent demand for large-scale, stable, and reliable hydrogen energy supply. The demonstration application of the ton-level magnesium-based solid-state hydrogen storage and transportation system in hydrogen metallurgy scenarios not only provides safe and efficient hydrogen supply assurance for hydrogen metallurgy but also, through testing in real industrial environments, further refines the engineering parameters of solid-state hydrogen storage and transportation technology. It explores coupling application modes with scenarios such as industrial waste heat, accumulating valuable experience for the large-scale promotion of this technology.
