DNV launches H2MET joint industry project to advance hydrogen flow metrology

DNV has launched the H2MET joint industry project (JIP) to advance metrology for 100% hydrogen flow applications. Building on previous work in renewable gases and CO2, H2MET aims to improve the accuracy and reliability of hydrogen flow measurement, ensuring a trusted foundation for hydrogen trading and supporting the role of hydrogen in a more efficient energy transition. 

  • The H2MET JIP addresses the critical need for metrology standards in the hydrogen sector, enabling the safe and efficient development of hydrogen trading and supporting global decarbonization efforts.
  • Hydrogen operators, technology providers, and metering manufacturers are invited to participate in this joint industry project to help shape the future of hydrogen flow measurement.
  • DNV’s Technology Centre in Groningen leads the H2MET project, positioning the facility as a global leader in hydrogen flow measurement.

As hydrogen plays an increasing role in global decarbonization, standardized and precise flow measurement is essential to ensure transaction integrity in the emerging hydrogen economy. Through this initiative, DNV’s Technology Centre in Groningen, Netherlands, will provide an advanced testing environment for hydrogen operators and technology providers to validate metrology solutions. The project will contribute to the development of essential measurement standards, fostering industry readiness for hydrogen’s expansion in energy systems worldwide. 

“The H2MET project is a crucial step in driving technological advancements for hydrogen trading,” said Øyvind Nesse, Senior Vice President at Equinor. “By ensuring that hydrogen flow measurement technologies meet the required standards of accuracy and reliability, we are contributing to a safer and more efficient energy transition.”

"As hydrogen markets mature, robust metrology will be essential to ensure transparency, accuracy, and trust in hydrogen trading,” explained Prajeev Rasiah, Executive Vice President and Regional Director for Northern Europe, Energy Systems at DNV. “By bringing together industry leaders in the H2MET JIP, we are not only addressing technical challenges but also laying the foundation for a globally recognized hydrogen measurement framework—critical for scaling hydrogen as a cornerstone of the energy transition.”

The H2MET JIP provides a platform for industry collaboration, enabling participants to share knowledge and establish operational limits for hydrogen flow metering. Central to the project is a highly accurate, traceable reference system that will assess the performance of various hydrogen metering technologies, supporting the European hydrogen flow traceability chain and future hydrogen trading. 

H2MET will also evaluate different metering technologies, drawing on DNV’s 50 years of expertise in natural gas flow measurement and its world-class testing facilities. As one of the few organizations globally equipped for advanced hydrogen flow research, DNV offers advanced testing and validation services to support industry adoption. 

“DNV’s expertise in flow metrology—backed by PTB-approved accuracy standards and world-class facilities in Groningen—places us at the forefront of hydrogen metrology innovation,” said Ronald ten Cate, DNV’s Business Lead for Hydro(Carbon) Flow Metering. “H2MET is driving industry-wide efforts to standardize hydrogen flow measurement, establishing trusted guidelines and technologies essential for the hydrogen economy.” 

As the energy transition accelerates, H2MET provides crucial support for hydrogen operators and technology providers, helping them develop reliable metering solutions. It also marks a key milestone in DNV’s commitment to global decarbonization.    

The H2MET project is still open for  participants to join in this vital industry collaboration. Interested parties can learn more and register their involvement via the H2MET web page.

Results will be available to JIP members in Q1 2026.
