Solid-State Hydrogen Storage Device by the National Innovation Center: A Revolution in Hydrogen Circulation Supply Technology

Recently, the China Productivity Promotion Center Association announced the list of selected projects for the 2023 "China Good Technology" project library. Among them, the "Hydrogen Circulation Supply Solid-State Hydrogen Storage Device Project" by the National Innovation Center stood out and was successfully selected (Category C). This achievement marks a significant breakthrough for China in the field of solid-state hydrogen storage technology.

The hydrogen circulation supply solid-state hydrogen storage device developed by the National Innovation Center addresses challenges in traditional solid-state hydrogen storage devices, such as slow dynamic response in hydrogen absorption and desorption, difficulties in large-scale design, and low levels of automation control. It adopts a new technology that matches and couples rare earth hydrogen storage materials with solid-state hydrogen storage systems. This innovative design not only optimizes the heat dissipation structure of the hydrogen storage system but also successfully meets the hydrogen storage needs of various application scenarios. Specifically, the device significantly enhances the heat exchange rate of hydrogen storage materials during hydrogen absorption and desorption processes through solid-state hydrogen storage thermal management technology, achieving a leading level both domestically and internationally. Preliminary tests show that compared to traditional hydrogen storage devices, this device improves the hydrogen absorption and desorption rate by nearly 30% and increases heat exchange efficiency by over 25%.

In addition to technological innovation, the National Innovation Center is also committed to enhancing the safety and intelligence of hydrogen storage systems. To this end, they have developed an automatic control logic and safety warning system for large-scale hydrogen energy storage systems. This system can monitor the operating status of hydrogen storage devices in real time, promptly detect and warn of potential safety hazards, thereby effectively ensuring the stable and safe operation of solid-state hydrogen storage systems in hydrogen energy storage and hydrogen recycling applications. Data shows that in simulated tests, the safety warning system can respond to abnormal situations within 0.1 seconds, significantly improving the overall safety of the system.

Previously, the hydrogen circulation supply solid-state hydrogen storage device product developed by the National Innovation Center had successfully obtained recognition as the first set of key components at the autonomous region level, further proving its technological advancement and practicality. The successful R&D of this device not only provides new technical support for China's hydrogen energy industry but also opens up new avenues for the diversified application of rare earth materials.

Looking ahead, the National Innovation Center is expected to continue staying at the forefront of technology, focusing on market demand, and striving to bridge the "last mile" of technology commercialization. They plan to further optimize the performance of the hydrogen circulation supply solid-state hydrogen storage device, reduce production costs, and promote its application in more fields. Meanwhile, the National Innovation Center will also strengthen cooperation with upstream and downstream enterprises in the industry chain to jointly drive the rapid development of the hydrogen energy industry, injecting strong momentum into China Northern Rare Earth's efforts to build a world-class rare earth leading enterprise and play a key role in the construction of the "two rare earth bases."
