Overview

EN ISO 24078:2025 (ISO 24078:2025) - Hydrogen in energy systems - Vocabulary - is a harmonized European/International vocabulary standard prepared by ISO/TC 197 in collaboration with CEN-CENELEC JTC 6. It establishes the terms, definitions, symbols and abbreviations used across hydrogen-related energy systems. The standard provides high-level, standardized language to improve clarity and interoperability among standards, regulators and industry stakeholders.

Key points:

Purpose: standardize terminology for hydrogen in energy systems (gaseous and liquid hydrogen, hydrogen-based fuels, infrastructure, safety, metrology, etc.).

Not applicable to: biological methanation; reactors for hydrogen production from other sources; road, maritime and aviation transport; aeronautics and space (these are planned for future editions).

Excludes carbon capture, storage and utilisation, and services.

Adopted as EN ISO 24078:2025 and expected to be implemented by CEN members as national standards (implementation deadline: January 2026).

Key topics

EN ISO 24078:2025 organizes vocabulary into clear technical categories, including:

Energy and energy carriers (e.g., hydrogen, hydrogen-based fuel, liquid hydrogen)

Energy systems and markets (integration, smart grid interactions)

Electric power networks and electrical energy storage

Hydrogen production systems and equipment (electrolysis, production-related terms)

Hydrogen infrastructure (components, stations, transmission, distribution)

Hydrogen storage (types and storage-related vocabulary)

Hydrogen-fuelled heat and power generation devices (fuel cells, turbines)

Hydrogen-to-X pathways and gas mixtures

Safety, risk reduction and hydrogen detection

Metrology, quality of energy carriers, testing, certification and materials compatibility

The document is primarily a terminology resource - it defines and standardizes language rather than prescribing engineering requirements or test methods. It also references related standards where more technical specifications are available (for example, ISO 14687:2019 for hydrogen fuel quality and ISO/IEC terminology resources).

Applications and users

Who benefits:

Standards writers and technical committees aligning cross‑disciplinary documents

Engineers and system integrators designing hydrogen systems and infrastructure

Regulators and policymakers drafting legislation and permitting frameworks

Certification bodies, metrology labs and testing organizations

Manufacturers, suppliers and project developers ensuring consistent definitions in procurement and contracts

Researchers and educators seeking standardized terminology for publications and training

Practical uses:

Ensuring consistent definitions in technical specifications, safety plans and contracts

Clarifying interfaces between electrical systems, hydrogen production (power‑to‑hydrogen) and storage

Improving interoperability across national and international hydrogen projects
