The EMPIR Metrology for Hydrogen Vehicles project is in great demand by the hydrogen industry as can be evidenced by the 45 letters of support received from hydrogen vehicle manufacturers (including BMW, Daimler and Toyota), hydrogen refuelling station (HRS) operators, gas producers and standardisation bodies.

A large hydrogen infrastructure is currently in development across Europe however the industry faces the dilemma that they are required to meet certain measurement requirements (set by European legislation) that cannot currently be followed due to the lack of available methods and standards. The EMPIR Metrology for Hydrogen Vehicles will be the first large scale project of its kind that will tackle these measurement challenges.


In order to properly determine the main measurement needs, a survey was undertaken involving key stakeholders of the hydrogen industry (including hydrogen producers, station operators, automotive manufacturers and standardisation bodies) to understand the measurement challenges that this industry currently faces. The results clearly demonstrated that there are four key technical measurement challenges that prevent a hydrogen economy from growing in Europe:


To address the four measurement needs detailed above, the project will designate four technical work packages to focus on each of them. In order to ensure that the technical work is effectively delivered to the stakeholders and end-users, a fifth work package will focus on creating impact. Therefore, the five objectives of this project are:

Progress beyond the state of the art

The current state-of-the-art for the objectives above and the planned outcomes from this project are:
