A new international research initiative has been launched to measure hydrogen emissions from operating infrastructure in North America and Europe, addressing the current lack of empirical data in this field. Industry leaders such as Air Products, Air Liquide, Shell, and TotalEnergies, in collaboration with academic scientists and research firms, are working together to quantify hydrogen emission rates across the hydrogen value chain. Cutting-edge technology, including high-precision hydrogen analyzers, is being used to detect and characterize hydrogen emissions with exceptional accuracy and speed, providing valuable insights for various stakeholders. The study, led by Cornell University, aims to inform best practices for deploying hydrogen at scale, improving leak detection, and reducing emissions to support the global transition towards decarbonization. The research initiative has received praise for its collaborative approach and the use of rigorous scientific methods to address the emissions challenges associated with hydrogen. By combining data gathered from operating facilities with industry expertise, the study seeks to contribute scientifically validated evidence to this environmental issue. The ultimate goal is to create a comprehensive dataset that can guide policies and practices to prevent leaks and other emissions from hydrogen systems. The study, fully funded by philanthropic contributions, began in March and is expected to continue until early 2026. Data collected will be published in peer-reviewed journals and made publicly available to advance scientific understanding and support informed decision-making in the hydrogen sector.
