Spinning Forming Technology Breaks Through Manufacturing Bottlenecks of Large Thin-Walled Hydrogen Storage Tanks, Enhancing Safety in New Energy Storage Driven by the Dual Carbon Goals, hydrogen energy is accelerating its industrialization as a clean energy carrier. However, the safety of hydrogen storage tanks has always been a major pain point for the industry. Traditionally welded hydrogen storage tanks pose risks of leakage at the welds and struggle to balance lightweight design with high strength. Recently, a “seamless spin forming process” based on powerful spin forming technology has achieved a significant breakthrough in the manufacturing of large hydrogen storage tanks, offering a new solution for improving the safety and efficiency of hydrogen energy storage. This process employs a combination of “pre-stretching + powerful spinning forming + necking/closing” technology, in which high-strength aluminum alloy or composite material blanks are plastically deformed point by point using spinning rollers, directly forming an integrated cylinder with uniform wall thickness and no welds. Compared to traditional welding, spin-formed hydrogen storage tanks eliminate over 90% of potential leak points, while controlling wall thickness variation within ±0.2 mm and increasing hydrogen storage density by 15%.
