Who is designing Type IV hydrogen storage cylinders and their core components?
2025-05-16
With the development of the hydrogen energy industry and the rapid promotion and industrialization of hydrogen fuel cell vehicles, Type IV hydrogen storage cylinders (plastic inner liner fiber-wound cylinders) have become a new direction to effectively promote the development of the hydrogen fuel cell vehicle industry due to their lightweight, high-pressure, high hydrogen storage capacity, and fatigue resistance characteristics.
Furthermore, in June of this year, the national standard for Type IV cylinders was officially implemented, breaking the previous predicament of lacking standards and further promoting the market application of Type IV cylinders.
At the same time, many domestic companies have announced their Type IV hydrogen storage cylinder production capacity, laying the foundation for the future mass production of Type IV hydrogen storage cylinders. According to incomplete statistics from Shiyin Energy Chain, the currently announced annual production capacity of Type IV hydrogen storage cylinders in China has exceeded 100,000 units, and the overall production capacity is expected to reach 400,000 units/year by 2025.
However, from a practical perspective, since the trial implementation of the national standard last year, the application of Type IV hydrogen storage cylinders in China has not seen an explosive development, nor has it achieved mass application like Type III hydrogen storage cylinders, and the overall industry is still in its early stages of development. This is mainly due to the limitations in the current forming process, manufacturing materials, and localization of core components for Type IV hydrogen storage cylinders, with the development of various components still in its infancy.
Therefore, overall, although the domestic hydrogen energy industry generally demands lightweight, high-pressure, high hydrogen storage capacity, long lifespan, and low cost, which will gradually promote the future application of Type IV hydrogen storage cylinders, breakthroughs in the "bottlenecks" of materials and processes are also imminent.
