Hydrogen in energy systems - Vocabulary (ISO/DIS 24078:2023)
The scope of standard on Vocabulary of Hydrogen in Energy Systems, presented in Figure 1, is aligned with the scope of JTC 6.
Therefore, the work aims to cover the fields of systems, devices and connections for the production, storage, transport and
transmission, measurement and use of hydrogen from renewable energy sources and other sources, in the context of the European
strategy for the development and acceptance of the hydrogen market. The scope includes cross cutting items such as: terminology,
Guarantee of Origin, interfaces, operational management, relevant hydrogen safety issues, training and education.
Flammability and explosion limits, as well as taxation issues, are outside the scope of EN to be drafted by JTC6 WG1.
Standard on the Hydrogen in Energy Systems will focus on description of the respective systems, the role of hydrogen within those
and on the most principal/basic devices. The standard will not describe different types of electrolysers, nor go into the efficiency or
taxation issues.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document has been prepared by Technical Committee CEN-CENELEC/JTC 6 Hydrogen in Energy
Systems, WG1 Terms and Definitions, in Vienna Agreement regulated collaboration with ISO TC 197
Hydrogen Technologies.
This is a first edition of EN/ISO 24078:202X. This document is intended to be used as a guiding
document providing basic terms and definitions explaining the role of hydrogen in energy systems, and
references the reader to get familiar with standards, technical reports, glossaries, guides etc., covering
specific fields for further/more detailed vocabulary.
Any feedback or questions on this document should be directed to the user’s national standards body. A

ISO/DIS 24078:2023(E)
Introduction
This document was developed under the Vienna Agreement, by CEN/CLC JTC 6 and ISO TC 197, under
the CEN lead.
In this document, terms and definitions have been identified, reviewed and proposed in order to cover
technical aspects for hydrogen in energy systems, with input from sources such as ISO/IEC Standards,
European Standards from CEN and CENELEC, national standards, and existing definitions from the
dictionaries relevant to particular industries.
This document only contains terms used to describe hydrogen in energy systems within the scope of
CEN/CLC/JTC 6.
The definitive intention of this document is to present the basics of the concepts that are subjected to
standardisation in the fields related to hydrogen in energy systems. Therefore, this document consists
of high level terms and definitions, and guides the reader to more specific standards/documents, where
more technical details can be found.
Terms and definitions are categorized in the following structure:
— energy carriers,
— energy system, energy infrastructure, smart grid and energy systems integration,
— electric power network and electrical energy storage,
— hydrogen production from electricity and other methods for hydrogen production,
— hydrogen production equipment,
— transmission, distribution and storage in dedicated hydrogen infrastructure and gas network, as
well as hydrogen admixture into natural gas and separation,
— hydrogen heat and power generation devices,
— power-to-hydrogen, hydrogen-to-X and energy storage,
— cross cutting items such as: hydrogen safety issues, metrology, quality of energy carriers,
certification and materials compatibility.
Note It is not an intention of this document to standardise legislator activities of any kind, nor to standardise
commercial products
