The H2FlowTrace consortium has completed the assembly of a Large-Scale Transfer Skid (LSTS) at the facilities of the VSL, the National Metrology Institute of the Netherlands. The LSTS will enable to provide direct traceability to measurement units for pure hydrogen and hydrogen blend gas flow, increasing the use of hydrogen in the European gas networks and therefore, uptake of hydrogen towards the energy transition.
The LSTS is a 6” diameter transfer standard delivering direct H2 gas flow traceability at large scale (i.e., > 1000 m3/h at pressures up to 65 bar, targeting uncertainties around 0.3%). CESAME EXADÉBIT, the German National Metrology Institute (PTB), the Slovak Institute of Metrology and VSL combined their world-leading expertise to design the LSTS. Moreover, the University of Bologna supported the assembly of the LSTS, creating a Piping and Instrumentation Diagram. Now, the LSTS will be sent to RMA Pipeline Equipment’s facilities, where the first field tests will be conducted.
After those tests, the project will hold a workshop in Q4 2026, detailing the key features of the LSTS: the first measurement results and future services provided, the design and commissioning of the LSTS, and the estimated calibration and measurement capabilities.

Once the successful field test has taken place, H2FlowTrace will reach its very ambitious objective of delivering direct H2 gas flow traceability for the European Hydrogen Backbone. This is a necessary foundation to ensure that hydrogen can be measured consistently and reliably for transportation, balancing, billing, and cross-border trade.
