This report describes the use of the online gas analysers, whose validation is described in the Metrology for Advanced Hydrogen Storage Solutions (MefHySto 19ENG03) D1 “Report on the development of new metrology for the measurement of key impurities in hydrogen (water vapour and
oxygen) produced from PEM water electrolysers, with fast response times of a few or tens of seconds”, to make quality measurements of the hydrogen produced by a number of laboratory-based and industrial electrolysers available to the project partners.
Demonstrations of measurements of key impurities (including water vapour and oxygen) in hydrogen generated from electrolysis (i.e. power-to-gas), were made in-situ. Where possible, the trial conditions simulated rapid changes representative of fluctuations in electrical grid supply (i.e. rapidly imposed transient use periods (0–100 %, 200 % peak).
This report presents the hydrogen quality measurement results and discusses the findings.
