Full title and description

AS ISO 16111:2020 — Transportable gas storage devices — Hydrogen absorbed in reversible metal hydride. This Australian adoption republishes the ISO technical content that specifies requirements for the material, design, construction and testing of transportable hydrogen storage assemblies (metal hydride assemblies) with shells up to 150 L internal volume and a maximum developed pressure up to 25 MPa.

Abstract

This document sets out requirements and test methods for refillable transportable metal hydride (MH) hydrogen storage assemblies (MH assemblies) intended for hydrogen as the only transferred medium. It covers service conditions, design and construction principles, material selection, pressure rating and marking, inspection and testing (including pressure and leak tests), and safety provisions; it excludes MH assemblies intended as fixed onboard vehicle fuel storage.

Scope

Applies to refillable transportable metal hydride hydrogen storage assemblies (MH assemblies) using shells not exceeding 150 L internal volume and with maximum developed pressure (MDP) not exceeding 25 MPa. Covers material, design, construction, testing, markings and documentation for safe manufacture, handling and operation; excludes MH assemblies intended as fixed onboard vehicle fuel storage.

Key topics and requirements

• Definitions and terms specific to metal hydride storage assemblies.
• Service conditions and pressure classifications (MDP up to 25 MPa, temperature and environmental considerations).
• Material selection and compatibility for hydrogen service (resistance to hydrogen-induced effects, suitability of shells, linings and non-metallic components).
• Design and construction requirements for shells, closures, valves and fittings.
• Pressure-containing component testing: hydrostatic / pneumatic testing, leak testing and proof pressure requirements.
• Inspection, marking, documentation and traceability (serialisation, technical file, user instructions and maintenance guidance).
• Safety provisions including pressure-relief devices, protection against overpressure and requirements for transportable use and refilling operations.

Typical use and users

Used by manufacturers and designers of transportable hydrogen storage systems (metal hydride assemblies), test and certification laboratories, conformity assessment bodies, system integrators using metal hydride storage for hydrogen delivery (e.g., trailers, portable supply units), hydrogen safety engineers, procurement teams and regulators responsible for safe hydrogen handling and transport.

Related standards

Commonly referenced standards and series that interact with or complement ISO 16111 include ISO 11114 (compatibility of cylinder and valve materials with gas contents), ISO 19880 series (gaseous hydrogen — fuelling stations and delivery), ISO 17268 (gaseous hydrogen refuelling connection devices) and national/adopted codes for pressure equipment and transportable vessels; consult ISO/TC 197 and relevant national bodies for authoritative cross-references.

FAQ

Q: What is this standard?

A: An international technical specification (adopted by Standards Australia as AS ISO 16111:2020) that defines requirements for transportable hydrogen storage devices using reversible metal hydride systems.

Q: What does it cover?

A: Material, design, construction, pressure and leak testing, inspection, marking and documentation for refillable transportable metal hydride hydrogen storage assemblies with shells ≤150 L and MDP ≤25 MPa; it excludes fixed onboard vehicle fuel-storage assemblies.

Q: Who typically uses it?

A: Manufacturers, test labs, conformity assessment and certification bodies, hydrogen system integrators, safety engineers and regulators dealing with transportable hydrogen storage and supply.

Q: Is it current or superseded?

A: The ISO edition underlying the AS adoption is ISO 16111:2018 (Edition 2); AS ISO 16111 was published in 2020 as the Australian adoption and is treated as the current national adoption of that ISO edition. Users should check with Standards Australia or ISO for any subsequent amendments or confirmations.

Q: Is it part of a series?

A: It is part of the wider set of hydrogen-related standards developed under ISO/TC 197 (hydrogen technologies); it is commonly used alongside other standards on hydrogen refuelling, material compatibility and pressure equipment.

Q: What are the key keywords?

A: Hydrogen, metal hydride, transportable storage, MH assembly, pressure testing, material compatibility, refillable, Standards Australia, ISO 16111.
