Understanding the behavior of non-ferrous materials in gas networks exposed to hydrogen
From the CANDHy project (supported by the Clean Hydrogen Partnership) we continue to advance in the evaluation of the compatibility of non-ferrous metallic materials with hydrogen, a key step towards the decarbonization of gas infrastructures.
The March newsletter summarizes the progress of Work Package 2 (WP2), which focused on:
• A detailed inventory of materials used in gas networks across 29 European countries
• Analysis of existing standards and testing codes for hydrogen compatibility
• A comprehensive literature review on degradation mechanisms, including hydrogen embrittlement
• Identification of regulatory gaps and future research needs
These findings are currently being used to develop 16-bar testing protocols on critical materials such as cast iron and brass, both in new and aged conditions.
Participating in initiatives like CANDHy allows us to contribute to building a safer, more efficient, and sustainable energy infrastructure — ready for the hydrogen future.
