Risk assessment of electrolyser failure: Analysis of grid faults and grid-serving behavior
Over the next decade, the installed capacity of electrolysers will increase from a few hundred megawatts to several gigawatts. In the current coalition agreement, the German government plans to increase the capacity of electrolysers up to 10 GW by 2030. Due to the existing gas infrastructure for hydrogen and the proximity of surplus wind power, the northern German grid is expected to experience an accumulation of grid connection requests. The uncoordinated loss of several gigawatts of electrolyser load due to a grid fault poses a high risk to dynamic stability. This study provides a qualitative risk assessment of the impact of an electrolyser loss and evaluates the advantages and disadvantages of different technical requirements for grid connection.
