Prospects Analysis of Integrated-Wrapped Multi-Layer Vessels Used as High Pressure Gaseous Hydrogen Storage Vessels

High pressure gaseous hydrogen energy is the most mature technology of hydrogen utilizing. High pressure gaseous hydrogen storage involves with high pressure vessel. In this paper, the research of high pressure gaseous hydrogen storage vessel is reviewed, and the research progress of multi-layer vessel used as high pressure hydrogen storage vessel is especially introduced. An integrated multi-layer-wrapped cylinder which may be used as high pressure gaseous hydrogen storage equipment is analyzed. The cylinder consists of lining, internal cylinder and multi-layer laminates. Lining and internal cylinder are made of anti-hydrogen steel, while the laminates are wrapped outside the internal cylinder to the required thickness with integrated wrapping method. The circumferential and longitudinal welding seams can be staggered in each laminate. The hydrogen leaking detection device is located in each cylinder section. This cylinder is provided with bearing pressure, resistance to hydrogen, anti-burst, online safety monitoring and other characteristics, which offers a possible structure for the construction of high pressure hydrogen storage vessel.
