【Ten Years of Rapid Development in Chemical Engineering Equipment】1361–2023: Solid alloy hydrogen storage reactors with independent intellectual property rights

Thread Content

In December 2023, the solid-state hydrogen storage device developed by Sichuan Kexin United with Jiangsu Jicui Antai Chuangming Advanced Energy Materials Research Institute Co., Ltd. (hereinafter referred to as “Antai Chuangming”) was installed on-site and its system was tuned, and it is set to enter demonstration operation soon. This system not only possesses the basic advantages of solid-state hydrogen storage, such as high safety and high density, but also features hydrogen release at room temperature and rapid charging/discharging. In particular, its energy consumption metrics are excellent, making it one of the storage and transportation methods with the greatest potential for commercial development. It is foreseeable that highly secure solid-state hydrogen storage will play a key role in large-scale hydrogen storage, providing strong support for the use of energy storage as well as hydrogen fuel cells in actual production and daily life. All key components of the system are domestically produced and possess independent intellectual property rights. One of the core devices, the solid alloy hydrogen storage reactor, is the first of its kind developed by the company. Employing advanced design concepts, it takes into account various factors such as lower hydrogen damping and heat transfer damping in the reaction chamber, high heat transfer efficiency, lightweight design, and modularity; its unique design enables it to achieve excellent performance metrics. The technical capabilities to meet the requirements of solid hydrogen storage equipment for various application scenarios are already available. This solid-state hydrogen storage system will be used in the hydrogen energy demonstration project of Shandong Dongyue Group, forming a hydrogen-heat coupling system together with the water electrolysis for hydrogen production – hydrogen fuel cell – combined heat and power system. This project is a major scientific and technological demonstration project organized and implemented by the Ministry of Science and Technology and Shandong Province. It aims to provide effective solutions for China’s \"dual carbon\" goals, promote the integrated development of the hydrogen energy innovation chain and industry chain, and ensure that key hydrogen energy technologies, industrial development, and application scenarios remain at the forefront worldwide. Kexin Electromechanical will continue to strive to innovate and excel in the field of hydrogen energy equipment manufacturing, contributing to the sustainable development of clean energy.
