| 520 | _ | _ | |a Alkaline water electrolysis is considered a core technology for producing hydrogen on a large scale using renewable energy. Renewable energies characteristically exhibit a fluctuating and highly dynamic behavior. However, conventional electrolyzers are designed to operate under constant process conditions. To couple alkaline water electrolysis with renewable energy, efforts are needed to understand how dynamic operation impacts the durability of the electrolysis system.This work aims to evaluate the influence of intermittent operation on the durability of an alkaline electrolyzer. Within this study, the behavior of bare nickel electrodes responding to fluctuating potentials was evaluated. Several influencing factors were evaluated to investigate durability. Among these factors were various load types such as the holding of the potential and the cycling of the potential in triangular wave or square wave (Figures 1a-c). Furthermore, the response to a renewable energy input was investigated (Figure 1d). Ultimately, this will allow to elucidate the relation between performance losses during potential cycling and renewable load profiles.Overall, the research is critical in understanding how long-term performance will be affected as electrolysis shifts to an intermittent renewable power supply. The observations can provide metrics regarding future types and degrees of operational load to limit performance loss and can help assess long-term durability. |
