A new international research initiative is set to measure hydrogen emissions from operating infrastructure in North America and Europe, aiming to fill a current gap in empirical data. The study, involving global industry leaders such as Air Products, Air Liquide, Shell, and TotalEnergies, along with academic experts and technology development firms, seeks to quantify hydrogen emission rates at various facilities within the hydrogen value chain. Cutting-edge technology like high-precision hydrogen analyzers is being utilized to detect and characterize hydrogen emissions with unprecedented accuracy and speed, providing crucial information for producers, regulators, investors, and policymakers. The research effort, led by Cornell University, is building on a multi-year collaboration with the Environmental Defense Fund (EDF) to measure methane leaks and applying similar techniques to identify hydrogen emissions. The study, supported by philanthropic contributions and industry partnerships, aims to inform best practices for deploying hydrogen at scale and optimize its decarbonization potential. Field measurements began in March and will continue through early 2026, with data to be published in peer-reviewed journals and made publicly available. The collaborative nature of this initiative between academia and industry is expected to lead to a robust, data-driven understanding of hydrogen emissions and support informed decisions and investments in the sector.
