Recently, the Guangdong Provincial Laboratory of Advanced Energy Science and Technology Foshan sub-center (Foshan Xianhu Laboratory), together with Foshan Municipal People's Government, Wuhan University of Science and Technology and Foshan Nanhai District People's Government, has made progress in developing Type IV carbon fiber hydrogen storage cylinders using the dry winding process.
Hydrogen energy, which is seen as critical to solving energy and environmental crises, is part of global energy strategies. Safe, high-density hydrogen storage remains a challenge, with carbon fiber-wound composite cylinders a promising solution for high-pressure storage.
Supported by the Open Fund Key Project of Foshan Xianhu Laboratory, the Advanced Composite Structures Research Team developed plastic liners for Type IV cylinders and overcame challenges in the dry winding process such as yarn design, viscosity control, winding path planning, and tension management. They produced structural validation parts for Type IV cylinders that will undergo sealing, winding layer optimization, and pressure testing. This work aims to enhance the independent R&D platform for the design, manufacture and quality evaluation of composite hydrogen cylinders.
