Ten years of rapid development in chemical engineering equipment – praise for China’s prosperity and strength. This is just a starting point; more participation from everyone will make things even more lively. HaiChuan becomes even better with your involvement; we welcome everyone to join in the forum discussions and exchanges. ********************************************* In April 2023, the 50MPa and 98MPa high-pressure hydrogen storage containers developed by Lansi Heavy Equipment were successfully produced, marking a new breakthrough in the company’s efforts to develop such containers and signaling its entry into the stage of large-scale commercial application. During the development process, Lansi Heavy Equipment overcame challenges such as high density and large capacity hydrogen storage per unit volume, effectively meeting the requirements of the industry for hydrogen refueling stations operating at rated pressures of 35 MPa and 70 MPa. Through research on mechanisms such as leakage before explosion in high-pressure hydrogen storage containers, plastic collapse, brittle fracture, local transition strain, and fatigue failure, the structural design of the equipment was optimized. Meanwhile, by relying on performance tests under high-pressure hydrogen conditions, the problems of \"high-pressure hydrogen embrittlement\" in the equipment materials and welding joints, as well as the sealing challenges associated with high-pressure hydrogen storage devices, were resolved. By applying multi-layer wrapping forming technology and remote online leakage monitoring technology, high safety, larger size, and lower cost applications for hydrogen storage containers have been achieved. On the basis of completing the development of high-pressure hydrogen storage containers, Lansi Heavy Equipment will intensify its research efforts further, making breakthroughs in key technological areas along the hydrogen industry chain, including hydrogen production, application, testing, and refueling, thereby promoting the high-quality development of the hydrogen energy sector.
