A new international research initiative has been launched to measure hydrogen emissions from operating infrastructure in North America and Europe. The study, led by industry players like Air Products, Air Liquide, Shell, and TotalEnergies, aims to quantify hydrogen emission rates from different facilities in the hydrogen value chain. Academic scientists from Utrecht University, the University of Rhode Island, West Virginia University, and Cornell University are also involved in the research, along with research firms like Aerodyne Research, TNO, and Transport Energy Strategies. The study seeks to detect and characterize hydrogen emissions using analyzers and sensing platforms, focusing on facilities such as steam methane reformers, pipelines, compressors, fueling stations, and hydrogen-powered vehicles. The partners emphasize the importance of understanding hydrogen emissions to support sound policies and practices for preventing leaks and other emissions in existing and emerging hydrogen systems. Steven Hamburg from the Environmental Defense Fund highlighted the significance of the study in providing a collaborative effort to directly measure hydrogen emissions. The initiative aims to develop a data-driven understanding of hydrogen emissions to guide future investments in the sector. The study, fully funded by philanthropic contributions, began field measurements in March 2025 and is expected to continue through early 2026. The results will be published in peer-reviewed journals and made publicly available for further research and policymaking.
