Project partners

The project partners comprise the top European National Metrology Institutes and key players in the hydrogen industry. Together, we will address the key measurement challenges shown above by developing physical solutions and best practice recommendations through scientific studies, the results of which will be disseminated publically for use by anyone in the hydrogen industry.


This project has received funding from the EMPIR programme.
