The Joint Research Project (JRP) 20IND11 “Metrology infrastructure for high-pressure gas and liquified hydrogen flows” (MetHyInfra) is the first large scale industry project that will provide metrological infrastructure and traceability to tackle the measurement challenges, which are currently slowing down the hydrogen industry growth for several sectors. The project offers a holistic approach as it covers the measurement challenges for the flow sector over the entire range of use cases for pure hydrogen. As of today, there is no infrastructure available for the calibration of flow meters with hydrogen, neither for liquefied nor for medium (up to 3 MPa) or high-pressure (up to 100 MPa) hydrogen.  

The aim of this project is to ensure measurement traceability in the hydrogen distribution chain. Therefore, Critical Flow Venturi Nozzles (CFVN) will be established as standards for the use with high-pressure gas and a traceability route will be established for liquefied hydrogen. Without this, verifiable measurements will not be possible, and hydrogen will potentially not be accepted for use as an environmentally friendly energy gas.
