Design of High Pressurized Hydrogen Gas Cylinder for Hydrogen Storage

Abstract: The increasing demand for efficient and safe hydrogen storage solutions necessitates the optimization of hydrogen gas cylinders (HGCs) in terms of dimensions and material properties. This paper aims to propose the optimal dimensions for HGCs and explore alternative materials to address the limitations of conventional steel cylinders. Steel, while commonly used for HGCs due to its robustness, presents challenges such as increased weight and potential safety hazards under high-pressure conditions. To overcome these issues, this study investigates various materials that could offer improved safety and performance characteristics.The research involves the theoretical calculation of dimensions for a high-pressure vessel, using the ASME VIII-1 design code and Hoop’s stress theory to ensure structural integrity under operational conditions. The paper details the methodology for determining appropriate cylinder dimensions and evaluates different materials based on their mechanical properties and suitability for high-pressure applications. Results from this study highlight the comparative advantages of alternative materials over steel, focusing on aspects such as weight reduction, enhanced safety, and cost-effectiveness. The findings provide valuable insights for the design and CAD model of hydrogen gas cylinder with high pressures, contributing to more efficient and safer hydrogen storage solutions. This research not only addresses current limitations but also lays the groundwork for future innovations in hydrogen storage technology.
