QualyGridS-Standardized qualifying tests of electrolysers for grid services

摘要

The project QualyGridS establishes standardized testing protocols for electrolysers to perform electricity grid services. Low temperature alkaline and proton exchange membrane (PEM) electrolysers are both considered within the QualyGridS project. A variety of different grid services is addressed as well as multiple hydrogen end users. The protocols developed will be applied to both electrolyser systems with powers ranging from 50 up to 300 kW. Additionally, a techno‐economic analysis of business cases is realized covering the grid and market situations in the most relevant regions of Europe for large electrolysers (>3MW). The testing protocols and economic analysis also include the review of existing and possibly new key performance indicators (KPI) for electrolysers. An overview is given of multiple electricity grid services for TSOs, DSOs and/or peer-to-peer operators in Europe that could be performed by electrolysers.. The requirements for electricity grid services are simulated through dynamic tests of an electrolyser system.
