Electrolyzer Control Cabinet Wiring as a Holistic Approach

The demand for green hydrogen is expected to increase in the next years. As a result, the market for suitable production means such as electrolyzers will also increase. An essential step in meeting this growth is automating production steps, which have so far been mainly manual. A crucial part of electrolyzer production is the control cabinet assembly and wiring. Automating this production step promises high economic potential and an increased output. In this context, this paper proposes a concept for automated control cabinet wiring using industrial robots. The control cabinet of an alkaline electrolyzer is taken as a reference object and analyzed regarding its hurdles for automation. Based on this analysis, a cabinet redesign is proposed yielding a higher automation potential. Subsequently, a concept for automated wire assembly and wiring is presented. The concept includes two industrial robots, enabling maximum flexibility regarding wire supply and control cabinet wiring.
