|Abstract:||Under the European project NESSHY (Novel Efficient Solid Storage for HYdrogen), three inter-laboratory measurement campaigns were conducted to assess the hydrogen physi-, chemi-sorption behaviour of storage materials. These Round Robin Testing (RRT) exercises aimed, in the absence of related standard methods, to guarantee that the performance parameters of novel hydrogen storage materials as measured in different labs are comparable, to identify any weaknesses in the measurement steps, and to develop best practices proposals and recommendations for testing and data reporting. One RRT exercise focused on adsorption capacity measurements on a carbon based material. The other two were dedicated to thermodynamic and kinetic properties measurements on alanate and magnesium-based absorbants. A significant number of laboratories participated, including key international experimental facilities. The results obtained along with the respective statistical analysis made, will be presented. On the basis of the findings, a comprehensive collection of guidelines and best practices for the performance and reporting of sorption measurements will be proposed. The objective is to contribute with this work to the data harmonisation and the development of testing protocols for accurately and independently assessing the performance, safety and life cycle stability of hydrogen storage materials. This could ultimately serve future codes drafting and standardisation needs in the field.|
