“Protocols for characterisation of system components and electrolysis system assessment” regards detailed characterisation procedures for testing both relevant electrolysis components and balance-ofplant (BoP). The procedures addressed in this deliverable are defined to assess the electrolysis system both in stationary conditions and with reference to its capability to work in grid balancing service. The latter aspect deals with the dynamic behaviour of the electrolysis system and its capability to support the local electrical grid at the Emden city council, Germany. This grid shares a large amount of installed wind and solar power plants.
The specific contents of the deliverable D2.1 are:
- Definition of a set of protocols for assessing PEM water electrolysis (PEMWE) components i.e. mapping of system level requirements to component level requirements.
- Definition of a set of protocols for assessing the PEM electrolysis system under stationary conditions in terms of performance, efficiency & durability including accelerated stress tests (AST).
- Definition of a set of protocols for the assessment of PEM electrolysis system under specific duty cycles related to grid-service application and in field tests.
The protocols defined in D2.1 are aiming to enable a proper planning of the test activities especially those in WP3 to WP6. In particular, the protocols describe a set of characterisations of system components (BoP, control unit, full stacks, large area membranes, scaled-up catalysts and MEAs) and establish a data-set of characteristics for which progress is assessed in terms of durability, efficiency and performance. Specific efforts were addressed to include in this deliverable procedures from EU harmonised test protocols according to specific initiatives carried out in the framework of the FCH JU program.
