H2 Flow Trace

Flow measurement traceability for hydrogen in gas networks. Developing large-scale verified metrological infrastructure to perform traceable pure hydrogen and HENG flow calibrations for gas networks.

The project (23IND05 H2FlowTrace) has received funding from the European Partnership on Metrology, co-financed from the European Union’s Horizon Europe Research and Innovation Programme and by the Participating States.

9 Months of H2FlowTrace

9️⃣ nine months since we started! The consortium discussed end of May 2025 all the achievements to date and the exciting plans for the near future.

✅ Several activities are now complete: from progress on the development of the small and large scale transfer skids, to the preliminary list of flowmeter technologies for calibration. We will build on some of the inputs of Met4H2. Stay tuned as we progress on the preparation of our facilities for future testing with pure hydrogen and hydrogen blends. In the end, the planned European intercomparison will contribute to the need for robust  gas flow traceability.
