Full title and description

ASME TGP-1:2023 — Guidelines to ASME Standards in Hydrogen Value Chains. A guidance document that summarizes ASME and relevant non‑ASME standards for hydrogen production, transportation, storage and end‑use, to help practitioners identify applicable codes, adopt good practices, and align requirements across the hydrogen value chain.

Abstract

This report provides a consolidated overview of standards and publications relevant to hydrogen service and maps those standards to typical hydrogen value‑chain activities (production, transport, storage, distribution, and end use). It highlights which ASME codes and related standards apply in different parts of the value chain and offers guidance to users on selection and interpretation of standards for hydrogen applications.

General information

• Publisher: The American Society of Mechanical Engineers (ASME).
• ICS / categories: Relevant ICS areas include standardization and documentation, energy and heat transfer engineering, fluid systems and components, environment/health/safety, and manufacturing/processing (see product metadata).
• Edition / version: 2023 edition (TGP‑1:2023).
• Number of pages: 42 pages.

Scope

Guidance intended for practitioners who need to identify and apply ASME (and complementary non‑ASME) standards when planning, designing, constructing, commissioning, operating, inspecting, or maintaining equipment and systems for hydrogen service. The document covers the full hydrogen value chain — production, transportation, storage, and end use — and indicates where specific ASME codes and other standards are relevant.

Key topics and requirements

• Mapping of ASME codes and standards to hydrogen value‑chain segments (which standards apply to production, storage, piping, compression, fueling, etc.).
• Overview of critical ASME documents and topics for hydrogen (for example, piping standards, pressure‑containing equipment, inspection and testing practices, material and weld considerations).
• Considerations for materials, welding, and metallurgy when exposed to hydrogen service (embrittlement awareness and mitigation).
• Recommended inspection, testing and qualification approaches tailored for hydrogen applications.
• Quality assurance, documentation and compliance pathways to align hydrogen projects with applicable codes and regulatory expectations.
• Practical guidance on selecting appropriate standards and identifying gaps where project‑specific engineering judgment or additional requirements may be needed.

Typical use and users

Used by design and mechanical engineers, standards and compliance specialists, project developers, asset owners/operators, inspection and testing personnel, code officials, and ASME committee members who are involved in hydrogen projects or establishing hydrogen technical requirements. The guidance is also useful for procurement and quality teams who must ensure equipment and procedures meet the appropriate standards for hydrogen service.

Related standards

Commonly referenced ASME standards and documents in the hydrogen context include B31.12 (Hydrogen Piping and Pipelines), B31.3 (Process Piping), relevant BPVC sections for pressure equipment, applicable PTCs and test methods, plus additional ASME guidance documents covering inspection, welding, and materials. The ASME Clean Hydrogen resources list these and other relevant standards for hydrogen applications.

FAQ

Q: What is this standard?

A: ASME TGP‑1:2023 is a guidance report titled "Guidelines to ASME Standards in Hydrogen Value Chains" that consolidates and explains which ASME and related standards apply across hydrogen production, transport, storage and end‑use activities.

Q: What does it cover?

A: It covers mapping of standards to value‑chain segments, high‑level guidance on materials, design, testing, inspection and QA considerations for hydrogen service, and pointers to the specific ASME codes and other standards most relevant to hydrogen projects.

Q: Who typically uses it?

A: Engineers, code officials, project developers, equipment manufacturers, inspection and QA personnel, and anyone responsible for ensuring hydrogen systems are designed and operated in accordance with recognized standards.

Q: Is it current or superseded?

A: The document is the 2023 edition and is placed on stabilized maintenance; ASME indicates this version remains in effect and that requests for change are handled through ASME’s maintenance process. Users should verify the edition status before critical use.

Q: Is it part of a series?

A: TGP‑1 is a guidance publication focused on mapping ASME standards to a specific application area (hydrogen). It is complementary to the body of ASME codes (e.g., B31.12, B31.3, BPVC sections) rather than a sequential standard series; it serves as a cross‑reference and guidance tool for those codes.

Q: What are the key keywords?

A: Hydrogen, value chain, ASME, codes and standards, guidelines, piping, pressure equipment, inspection, materials, safety.
