Driving Widespread Access to Hydrogen Mobility: Atawey Achieves Legal Metrology Certification
As Atawey ramps up its industrial acceleration phase — with the production of four hydrogen refueling stations, each with a capacity of over one ton of hydrogen per day — the company has reached a significant milestone: the certification of its legal metrology system. This industrial innovation allows for precise measurement of the amount of hydrogen dispensed with each refill, ensuring accurate billing for users. This advancement, which complies with European Alternative Fuels Infrastructure Regulations (AFIR) and national standards, paves the way for the democratization of hydrogen refueling stations, making them accessible to all hydrogen vehicle drivers.
Legal Metrology Certification: A Guarantee of Reliability and Transparency for Users
After several months of collaboration with the National Laboratory of Metrology and Testing (LNE), Atawey has officially obtained certification for its ata’METRICS legal metrology system. This high-precision device, capable of measuring the amount of hydrogen dispensed with a resolution of 10 g and an accuracy of 2%, meets French regulatory requirements based on the international OIML R139 recommendation. This technological breakthrough was made possible through collaboration with Cesame Exadébit, a gas flow metrology laboratory equipped with COFRAC-accredited test benches.
The result: Atawey’s hydrogen refueling stations will enable transparent and precise billing for every fill-up, offering a level of accuracy comparable to that of conventional fuel stations.
« Collaborating with expert partners such as LNE and Cesame Exadébit was crucial in achieving this level of excellence and advancing our technological edge. For the sector, this certification demonstrates that hydrogen mobility is a tangible reality. For users, this certification means one simple thing: paying exactly for what they consume, with the same confidence as with a traditional fuel refill, says Guillaume Havard, » Product Manager for R&D at Atawey.
Hydrogen Sector Ramp Up: Atawey is Ready!
With an estimated 89,000 hydrogen-powered vehicles registered worldwide in 20241, Atawey positions itself as a key player and driving force in technological transition. With reliable, high-performance stations that meet international standards and regulatory requirements such as AFIR — now bolstered by this legal metrology certification — the manufacturer is opening the door to the deployment of public hydrogen refueling stations. One notable example is the Arv’Hy project in
France. These stations, designed to meet the needs of intensive mobility (both captive fleets and transit users), will become essential infrastructure for open access to hydrogen mobility.
To support this increased production rate, Atawey launched an ambitious industrialization program earlier this year, aiming to standardize the modules integrated into its stations. This modular, configurable approach is based on the design and production of serially manufactured modules that are then integrated into all its stations.
« The standardization of our stations is a direct response to the sector’s main challenge: rapidly deploying secure, reliable, and high-performance infrastructure. This industrial vision enables us to make hydrogen mobility viable on a large scale, » comments Pierre-Jean Bonnefond, co-founder and CTO of Atawey.
Through this strategy, Atawey’s stations combine flexibility with efficiency. Each module can be configured according to the specific needs of clients while benefiting from the robustness and reliability of a proven system. Among these modules, the legal metrology system is a key component.
