SUMMARY AND OBJECTIVES
The EMPIR Metrology for Hydrogen Vehicles will be the first large scale project of its kind that will tackle the four measurement challenges that currently prevent the industry from meeting requirements set by International Standards such as flow metering, quality control, quality assurance and sampling.
The specific objectives of the project are:
- Flow metering - To develop a metrological framework for testing hydrogen meters used to measure the mass of hydrogen dispensed into a fuel cell vehicle from a refueling station.
- Hydrogen quality assurance - To support hydrogen purity testing as specified in ISO 14687 by developing traceable offline gas analysis methods, stable and accurate primary reference gas mixtures and the metrological tools to enable the introduction of low cost gas analysers suitable for use by commercial gas analysis laboratories.
- Hydrogen quality control - To perform purity measurements of hydrogen following the implementation of quality control techniques specified in ISO 19880-8 and validate continuous online hydrogen purity analysers for measuring canary species at the HRS.
- Sampling - To develop a robust protocol for taking a representative sample of hydrogen gas from a refuelling station and testing suitability of high pressure sampling vessels for delivering hydrogen to gas analysis laboratories for offline purity analysis; as required by ISO 14687.
- Creating impact - To facilitate the take up of the technology and measurement infrastructure developed in the project by the measurement supply chain (accredited laboratories, instrument manufacturers), standards developing organisations (ISO, CEN/CENELEC) and end users (hydrogen industry, vehicle manufacturers and suppliers).
The Foundation for the Development of New Hydrogen Technologies in Aragon has an important paper on reaching the objective number four in which it has to work on the analysis of the samples that have to be taken at the hydrogen refuelling stations so as to approximate them to the laboratory state.
This Project has received funding from the EMPIR programme co-financed by the Participating States and from the European Union´s Horizon 2020 research and innovation programme.
