DNV has launched the H2MET Joint Industry Project (JIP) to advance metrology for 100% hydrogen flow applications, focusing on improving accuracy and reliability in hydrogen flow measurement. The H2MET initiative aims to set a trusted foundation for hydrogen trading and support the expansion of hydrogen in energy systems globally. With the project based in Groningen, Netherlands, DNV’s Technology Centre will offer a testing environment for hydrogen operators and technology providers to validate metrology solutions. The project will play a crucial role in developing essential measurement standards to ensure transaction integrity in the emerging hydrogen economy. The H2MET project is seen as a significant step in driving technological advancements for hydrogen trading by ensuring that hydrogen flow measurement technologies meet required accuracy and reliability standards. Industry collaboration within the H2MET JIP will enable participants to share knowledge, establish operational limits for hydrogen flow metering, and evaluate different metering technologies. Central to the project is the development of a highly accurate, traceable reference system to assess the performance of various hydrogen metering technologies, supporting the European hydrogen flow traceability chain and future hydrogen trading. DNV, with its expertise in flow metrology and world-class testing facilities, is at the forefront of hydrogen metrology innovation. The project not only addresses technical challenges but also lays the groundwork for a globally recognized hydrogen measurement framework critical for scaling hydrogen as a key component of the energy transition. By emphasizing the importance of standardized and precise flow measurement for transparency, accuracy, and trust in hydrogen trading, H2MET contributes to the global decarbonisation efforts and supports the role of hydrogen in a more efficient energy transition.
