Hydrogen energy is not only environmentally-friendly energy, but also ideal energy required by human beings. The large-scale popularization of the hydrogen energy mainly involves three important links: production, storage and transportation, and application. How to ensure the high efficiency and safety of a hydrogen storage technology is a key technology affecting the popularization and application of the hydrogen energy, and is also a key problem to be solved urgently at present. High-pressure hydrogen storage is generally considered as a promising hydrogen storage technology. The manufacturing and development of a high-pressure hydrogen storage vessel that serves as the main storage means of hydrogen energy determines the popularization speed of the hydrogen energy. The high-pressure hydrogen storage vessel includes a III type vessel and a IV type vessel, and takes a carbon fiber composite material layer as a main carrier of the pressure vessel, so that the safety performance can be ensured.
