Dissemination of project results towards international standards and committees. The project’s Task A6.1.8 focused on dissemination efforts to ensure a wide-reaching impact of its findings. Engagement targeted influential bodies including ISO/TC 197, IEC/TC 105, ISO/TC 158, CEN/TC 234, and more, aiming to introduce project outputs into committee discussions. These efforts involved requesting agenda time, delivering […]

This report describes the developed protocols for gas sampling (air and H2) and the validation of the subsequent analysis by in-tube extraction dynamic headspace coupled to gas chromatographymass spectrometry (ITEX-DHS-GC-MS) carried out at the University of A Coruña (UDC) for the determination of halogenated volatile organic compounds (VOCs). These compounds, if present in the input […]

The aim of this work (Metrology for Advanced Hydrogen Storage Solutions – MefHySto 19ENG03) is to address the need for the assessment of the quality of hydrogen produced from PEM water electrolysis during rapidly imposed transient use periods. This work focuses on quality measurements with online gas analysers for two key impurities in hydrogen (water […]
A database to select affordable MOFs for volumetric hydrogen cryoadsorption considering the cost of their linkers
A database to select affordable MOFs for volumetric hydrogen cryoadsorption considering the cost of their linkers was introduced by CIIAE – Iberian Centre for Research in Energy Storage and Bundesanstalt für Materialforschung und -prüfung. Physical adsorption at cryogenic temperature is a reversible mechanism that can reduce the pressure of conventional compressed gas storage systems. Metal–organic […]
