Preventing PFAS emissions from water electrolysers

PFAS-containing materials offer unique physical and chemical properties, making them highly relevant for hydrogen technologies. However, these substances are highly persistent and can accumulate in the environment, posing potential risks to human health and ecosystems.

Currently, there is limited understanding of how and to what extent PFAS are released during the operation of fuel cells and electrolyzers. In addition, standardized methods for sampling and analysis are lacking. Without this foundation, reliable risk assessment and mitigation strategies remain challenging.

The UPeM project aims to systematically assess PFAS emissions in hydrogen technologies and provide reliable evaluation methods. To achieve this, harmonized protocols for sampling and analysis of PFAS in liquids, gases, and aerosols are developed. At the same time, the project investigates the root causes of PFAS release during system operation.

The developed methodologies are validated under real industrial operating conditions to ensure practical applicability. Based on the results, the project derives recommendations for safe material use, mitigation strategies, and optimized operational and control approaches. A particular focus is placed on evaluating alternative membrane materials with potentially reduced PFAS emissions.

Through the collaboration of research institutions, industry partners, and technology providers, the project establishes a foundation for future standards in managing PFAS within the hydrogen sector.
