Overview
EN 17339:2024/prA1 sets forth the minimum requirements for the materials, design, construction, prototype testing, and routine manufacturing inspections of carbon composite gas cylinders and tubes used for the storage and transport of compressed hydrogen. This European Standard, developed by CEN, covers hoops wrapped (Type 2) and fully wrapped (Type 3 and Type 4) composite cylinders manufactured with carbon fibre reinforcements. The standard applies to gas cylinders and tubes intended for permanent installation in frame-mounted setups such as bundles or trailers, operating at test pressures of at least 300 bar and maximum working pressures up to 1000 bar.
The document ensures uniformity and safety in manufacturing hydrogen cylinders, which is critical as hydrogen fuel becomes increasingly important in transportation, industry, and energy storage applications.
Key Topics
Types of Cylinders Covered:
- Type 2: Hoop wrapped with seamless metallic liners.
- Type 3: Fully wrapped with seamless metallic liners.
- Type 4: Fully wrapped with non-metallic liners.
Performance Criteria:
- Maximum water capacity: 3000 liters
- Maximum working pressure: 1000 bar
- Product of working pressure and water capacity (p × V): ≤ 1,000,000 bar·l
Material Requirements:
- Specifications for carbon fibres and, where applicable, glass fibre protective layers on the cylinder exterior for added durability.
Manufacturing and Testing:
- Prototype and production batch testing for tensile strength, modulus, elongation, and other material properties to ensure compliance.
- Procedures for hydraulic pressurization cycle testing at temperatures ranging from 65°C to –40°C.
- Requirements for permanent cylinder components and their role in safety and impact resistance.
Certification and Documentation:
- Provision of type test certificates and documentation of material property tests per batch, supporting traceability and regulatory compliance.
Applications
EN 17339:2024/prA1 is an essential reference for manufacturers, quality assessors, and end users of high-pressure hydrogen storage cylinders and tubes. Practical applications include:
- Hydrogen Fueling Stations: Providing safe, standardized storage solutions for compressed hydrogen, supporting the rollout of hydrogen-powered vehicles.
- Transport and Mobility: Enabling the use of lightweight, high-strength hydrogen cylinders in commercial transport fleets, buses, trucks, and emerging hydrogen rail and marine vehicles.
- Industrial Hydrogen Supply: Ensuring conformity and safety in the bulk transport and onsite storage of hydrogen for industrial processes, laboratories, and energy storage systems.
- Trailer Bundles: Standardizing the design and inspection of frames and bundles used for large-volume hydrogen transportation by road.
The standard promotes the safe, efficient, and sustainable use of hydrogen storage technology - a core component of the evolving clean energy ecosystem.
