An open and comprehensive compendium
This report entitled EU harmonised terminology for hydrogen generated by electrolysis is
prepared under the FWC between JRC and FCH2JU. It is the result of a collaborative effort between European
partners from industry, research and development (R&D) organisations and academia participating to FCH2JU
funded R&D projects3 in electrolysis applications.
The objective of this pre-normative research (PNR) document is to present an open and comprehensive
compendium of harmonised terminology which are encountered in electrolysis applications. As means of
ordered knowledge representation, clarity of communication and open access to technical information, the
commonly accepted terms and definitions of this compendium cover electrolysis R&I aspects. These aspects
are materials research, modelling, design & engineering, analysis, characterisation, measurements, laboratory
testing, prototype development and field tests including demonstration as well as quality assurance (QA).
The commonly accepted definitions of terms and phrases may be used in RD&D project documents, test and
measurement methods, testing procedures and protocols, scientific publications, and technical documentation.
It is primarily intended for use by those involved in conducting RD&D as well as in drafting and evaluating
R&I programme but also contains information which may be useful for others such as auditors, manufacturer,
designer, system integrators, testing centres, service providers and educators. Note, the compendium is
expandable to account for future power-to-hydrogen (P2H2) developments in energy storage (ES) particularly
electrical energy storage (EES) and hydrogen-to-substance (H2X) applications.
