FLEXUM, Flexible operation of electrolyzers for minimal degradation using monitoring

Electrolyzers must have the capability to operate flexibly to meet the demand in a grid with fluctuating renewables. Furthermore, the cost of electrolyzers should be reduced for a more affordable and swifter green transition. The cost of the electrolyzer plants can be significantly reduced by increasing the lifetime of the electrolyzer stacks.

The aim of this project is to develop technology for monitoring and intelligently controlling electrolysis technologies to best possibly maintain the performance of the technology while meeting the flexibility demand of the grid. While monitoring equipment for large components such as wind turbines contemplates only a small fraction of the total cost, then for modular comparatively small units such as electrolysis stacks, the monitoring with state-of-the-art technology could contemplate an undesired high fraction of the total cost.
