After the successful first sampling event within the MetroHyVe 2 (Metrology for Hydrogen Vehicles 2) project with very interesting results in October 2022, a second comparison of hydrogen sampling systems organised by ZBT recently took place at the ZBT hydrogen test field in Duisburg.

A total of four sampling systems were compared (Air Liquide, NPL, Dr. Ryll Lab and ZBT) and eight samples were taken. A new feature was the simultaneous sampling by two sampling systems (NPL and ZBT) during a normal refuelling according to SAE J2601. The samples are now being analysed in the NPL laboratories. We are looking forward to further interesting results!

MetroHyVe 2 is an EMPIR-funded project that continues the work of MetroHyVe 1, but also has additional goals for testing impurities in hydrogen fuel cells.

Climate change, air quality and dependence on imported fuels from non-renewable sources require the rapid introduction of alternative fuels such as hydrogen to meet the targets for a carbon-neutral Europe (net zero transport emissions) by 2050. Currently, the large-scale introduction of hydrogen in transport is hampered by the European Directive 2014/94/EU and the recommendations of the International Organisation of Legal Metrology (OIML), which all European hydrogen refuelling stations must comply with.

MetroHyVe 2 addresses these issues and will develop metrology that clears the way for hydrogen as a conventional fuel and supports the European energy transition. The project addresses metrological challenges in the areas of flow measurement, quality control, hydrogen sampling and fuel cell stack testing.
