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. }, title = {EU harmonised terminology for hydrogen generated by electrolysis}, url = {}, doi = {10.2760/732809 (online),10.2760/293538 (print)} }
