Metrology for high-pressure gas and liquid hydrogen flows (MetHyInfra)
The European “Green Deal” sets out a roadmap for the greening of energy flows and a climate-neutral EU. Carbon-neutral solutions for transport and energy are a core element of the Green Deal, which requires investments in environmentally friendly green or blue hydrogen. Hydrogen offers the prospect of storing electrical energy obtained in a green manner in the natural gas network. The market for hydrogen is growing, for both the gas phase and the liquid phase. The need for a metrological infrastructure for fiscal metering of hydrogen transfer has therefore become more compelling.
In this project, traceability to the SI system for quantity measurement of hydrogen is developed, for both the gas phase and the liquid phase. In addition, the applicability of different flowmeter types for metering hydrogen is being investigated. Primary standards for the calibration of gaseous hydrogen sonic nozzles are being developed. Traceability to the liquid phase is achieved in three completely independent ways.
Our role
VSL leads the work package that has the following two objectives:
- Establish traceability for measurements on liquid hydrogen streams,
- Developing primary standards for the calibration of sonic nozzles that subsequently provide traceability for measurements of gaseous hydrogen.
To this end, VSL collaborates in this work package with ten sister/research institutes and industrial parties located in Europe.
VSL has so far been able to estimate the expected measurement uncertainty when measuring liquid hydrogen by means of modeling and has succeeded in calibrating liquid hydrogen flow meters and using them for measurements on liquid hydrogen flow.

Virtual experiments and digital twins (ViDiT)
Virtual experiments and digital twins are key enabling technologies to achieve and realise European strategic policies devoted to sustainability and digitalisation within the complex framework of Industry 4.0 and the European Green Deal.
Pushing boundaries of nano-dimensional metrology by light (20FUN02 POLight)
This project addresses this issue by developing novel methods to help bridge the metrology gap and in turn foster KET innovation. More specifically, this project will push the boundaries of optical measurement methods by realising a new generation of optical metrology systems, with unprecedented performances in terms of spatial resolution, traceability, reliability and robustness.
Traceable metrology of soft X-ray to IR optical constants and nanofilms for advanced manufacturing (20IND04 ATMOC)
The optics and semiconductor industries use innovative materials and complex nanostructures in their products whose optical properties are difficult to measure and often not accurately known. This project is developping advanced mathematical methods to traceably characterise these materials for wavelength ranges from soft X-ray to IR.
Traceable industrial 3D roughness and dimensional using optical 3D microscopy and optical distance sensors (20IND07 TracOptic)
To remain competitive, European manufacturers strive to make constant improvements in their manufacturing processes. The surface topography of a component part can have a profound effect on the function of the part. This is true across a wide range of industries (such as precision engineering, automotive and medical).
