Imagine trying to use a ruler designed for inches to measure centimeters; it just doesn't work accurately. Right now, the meters in our gas pipes are built for natural gas, not hydrogen. This work creates the 'rulebook' and testing methods to ensure these meters stay accurate and safe as we swap natural gas for green hydrogen.
Gas companies cannot safely or accurately transition to hydrogen because current meters aren't certified for H2NG mixtures. This creates a regulatory barrier that prevents the use of existing pipelines for green energy.
A set of validated testing protocols and methodologies to evaluate the accuracy, safety, and durability of gas meters using hydrogen blends up to 100%.
If you are a TSO dealing with the risk of inaccurate billing or leaks when mixing hydrogen into pipelines — this project developed testing protocols that verify if your high-pressure measuring devices can handle mixtures up to 100% hydrogen.
If you are a DSO dealing with outdated domestic meters that may fail with hydrogen blends — this project developed validated protocols to define the limits and tolerances of measuring devices in distribution grids.
If you are a manufacturer dealing with a lack of official standards for hydrogen-ready meters — this project developed a set of test gas definitions and methodologies to help you certify your devices for the H2NG market.
Based on available project data, there is no specific pricing or cost information provided for the resulting protocols or methodologies.
The project focuses on creating the standards and testing methodologies required for industrial scale, specifically targeting transmission and distribution systems with flowrates in the thousands of Sm3/h.
Based on available project data, the project aims to update international standards and foster innovation, but specific licensing terms are not mentioned.
It addresses gaps in the EN437:2018 standard and the lack of regulatory protocols for approving devices that operate in different H2NG mixtures.
The project runs from 2023-02-01 to 2026-12-31, meaning the final validated protocols will be available by the end of 2026.
The consortium is heavily weighted toward industrial application, with 6 industrial partners and 6 research institutes, resulting in a 43% industry ratio. Led by SNAM SPA, it combines the operational needs of TSOs and DSOs (like GRTGAZ and Enagás) with the technical precision of national metrology institutes (like METAS and INRIM), ensuring the resulting standards are both scientifically sound and commercially viable.
