QualyGridS - Standardized qualifying tests of electrolysers for grid services

Kurzfassung

The project QualyGridS will establish standardized testing protocols for electrolysers to perform electricity grid services. Alkaline electrolysers and PEM electrolysers will both be considered within the QualyGridS project. A variety of different grid services will be addressed as well as multiple hydrogen end users. The protocols developed will be applied to both alkaline and PEM electrolyser systems, respectively, using electrolyser sizes from 50 kW to 300 kW. Additionally, a techno‐economic analysis of business cases will be performed covering the grid and market situations in the most relevant regions of Europe for large electrolysers (above 3MW). Testing protocols and economic analysis will also include the review of existing and possibly set‐up of new Key Performance Indicators (KPI) for electrolysers. An overview of some electricity grid services in Europe, that could be performed by electrolysers, will be given. Dynamical tests of an electrolyser system will be presented simulating the requirements for electricity grid services.
