High-temperature water electrolysis (HTEL) is one of the most promising technologies for green hydrogen production, offering high energy efficiency and reduced reliance on critical raw materials. However, large-scale deployment is still hindered by challenges related to material durability, dynamic operating conditions, and degradation mechanisms. ELECTROLIFE aims to address these challenges by defining harmonised testing protocols for evaluating the performance and durability of HTEL components, cells, and stacks.
By establishing harmonised testing protocols and implementing detailed procedures, our deliverable report “Specification, Terminology, and Harmonised Protocols for High-Temperature Electrolysis (HTEL)”, full report D4.2 available here, provides the essential experimental foundation needed to analyse and validate degradation mechanisms. This structured approach enables partners to investigate how HTEL components and stacks respond to both steady-state and dynamic operating conditions, offering valuable insights into the effects of operational stress and material fatigue.
This work also plays a key role in assessing the impact of fluctuating power inputs, such as those typical of renewable energy sources. By simulating variable load profiles through carefully designed test procedures, the project can evaluate how intermittent operation influences system stability and long-term performance.
In parallel, the experimental data collected under standardised conditions serve as a reliable basis for validating the degradation models being developed within ELECTROLIFE. These models rely on accurate, consistent, and reproducible measurements. Moreover, the report directly addresses the need for standardised testing methodologies for HTEL technologies. By aligning with Joint Research Centre (JRC) recommendations and facilitating interoperability among different laboratories, the protocols help establish a common language and framework for evaluating performance and durability. The controlled testing of different use scenarios enables the consortium to identify the most favourable operating conditions, paving the way for more resilient and efficient system design.
Congratulations to CNR and all ELECTROLIFE partners on this achievement!
