Firstly, in terms of technological advancement, Type IV composite cylinders offer advantages such as lightweight, corrosion resistance, explosion-proof, and environmental friendliness. Compared to traditional steel cylinders, they offer higher safety and longer service life. For example, Type IV cylinders use high-density polyethylene inner liners and glass fiber-wrapped structures, which are transparent, corrosion-resistant, and have a long service life. Additionally, with the advancement of composite material technology, such as carbon fiber winding technology, the performance and cost-effectiveness of Type IV cylinders have further improved.
Secondly, in terms of market application, Type IV composite cylinders show promising applications in various fields. For example, in the storage of liquefied petroleum gas (LPG), Type IV cylinders are gradually replacing traditional steel cylinders due to their lightweight, safety, and environmental benefits. In the hydrogen energy sector, Type IV hydrogen storage cylinders, with their lightweight, high hydrogen storage density, and long service life, are becoming an important choice for on-board hydrogen storage systems. Additionally, with the promotion of hydrogen fuel cell vehicles, the demand for Type IV hydrogen storage cylinders is also growing rapidly.
In terms of policies and standards, the standardization and regulation of Type IV composite cylinders are continuously advancing. For example, China is developing the national standard "Liquefied Petroleum Gas High-Density Polyethylene Inner Liner Glass Fiber-Wrapped Cylinder" to promote the standardization and internationalization of LPG-IV cylinders. Moreover, governments and enterprises are actively investing in the research, development, and production of Type IV cylinders to meet market demands.
However, the development of Type IV composite cylinders still faces some challenges, such as the cost control of key materials (e.g., carbon fiber), optimization of manufacturing processes, and the molding technology of plastic liners. Additionally, despite the advantages of Type IV cylinders in performance and cost, their market promotion in certain applications (e.g., domestic) still faces regulatory and market acceptance challenges.
Overall, the development trend of Type IV composite LPG cylinders is toward lightweight, intelligent, environmentally friendly, and standardized development. In the future, they will play an increasingly important role in energy storage, transportation, and industrial sectors.
