A significant collaborative research study has been launched in Rotterdam, Netherlands, to measure real-world hydrogen emissions from operating infrastructure in North America and Europe. This initiative aims to fill the current data gap concerning hydrogen emissions and provide valuable insights for stakeholders in the industry. The research consortium includes global industry leaders such as Air Products, Air Liquide, Shell, and TotalEnergies, along with academic scientists and technology development firms. Cutting-edge technology, including high-precision hydrogen analyzers, is being utilized to quantify emissions from various facilities in the hydrogen value chain with unprecedented accuracy and speed. Dr. Thomas Röckmann from Utrecht University emphasized the study's scope and the importance of gathering representative data to address environmental concerns related to hydrogen emissions. Although hydrogen shows promise in decarbonizing challenging sectors like heavy industry and long-distance transport, its emissions must be managed effectively to maximize its benefits. The study will play a crucial role in providing data-driven insights for policymakers and industry players. Multiple industry representatives highlighted the significance of the study in advancing the understanding of hydrogen emissions and promoting sustainable practices. Field measurements commenced in March 2021 and will run until early 2026, with the data set to be shared in peer-reviewed journals for transparency and further research. The study, fully funded by philanthropic contributions to the Environmental Defense Fund, underscores the collaborative effort between academia and industry to address emissions challenges in the hydrogen sector.
