EU harmonised testing procedure: Determination of water electrolyser energy performance
The objective of this pre-normative research (PNR) document is to present a testing procedure for establishing the energy performance of water (steam) electrolyser systems (WE systems), whether grid-connected or off-grid and individual water electrolysers (WEs)/high-temperature electrolysers (HTEs) for the generation of hydrogen by water/steam electrolysis. The WE systems use electricity mostly from variable renewable energy sources. HTE may additionally utilise (waste) heat from energy conversion and other industrial processes. By applying this procedure, the determination of the specific energy consumption per unit of hydrogen output under standard ambient temperature and pressure (SATP) conditions allows for an adequate comparison of different WE systems. The energy efficiency and the electrical efficiency based on higher and lower heating value of hydrogen can be derived from respectively the specific energy consumption and the specific electric energy consumption as additional energy performance indicators (EPIs). In a plant setting, the specific energy consumption of an individual water electrolyser including HTE under hydrogen output conditions may also be determined using this testing procedure. This procedure is intended to be used as a general characterisation method for evaluating the energy performance of WEs including HTEs and systems by the research community and industry alike. ; JRC.C.1 - Battery and Hydrogen Technologies
