| contents | The transition to a low-carbon economy relies heavily on the deployment of renewable hydrogen as a key energy vector. Electrolyzers, particularly PEM technology, play a central role in this transition, yet their intermittent operation presents significant challenges. Understanding the impact of intermittency on electrolyzer performance is essential to ensuring the reliability and cost-effectiveness of large-scale hydrogen production projects. This knowledge is critical not only for mitigating risks but also for accelerating the deployment of low-carbon hydrogen at scale. Despite its importance, the current literature reveals a lack of quantitative studies addressing the specific effects of intermittency on electrolyzer performance, alongside an absence of dedicated methodologies for its characterization [1].<br><br>Previous experimental studies on a 55 kW semi-industrial pressurized PEM electrolyzer have suggested that dynamic electrical load fluctuations over hourly timescales do not significantly affect system performance compared to the average operating point. These results indicate that the electrolyzer can withstand certain types of intermittency without notable losses in efficiency or performance [2]. However, other critical aspects of intermittency remain underexplored, particularly the influence of fluctuation in operational states on system efficiency and overall lifespan.<br><br>Modeling offers a unique advantage in simulating scenarios that are impractical to study experimentally. In this research, a performance model was created in MATLAB/Simulink to specifically analyze the impact of operational state intermittency. The model was implemented on the 55 kW semi-industrial pressurized PEM electrolyzer and validated against experimental operational data. This study delivers key insights into optimizing electrolyzer performance under intermittent conditions, contributing to the design of resilient and efficient hydrogen production systems integrated with renewable energy sources. |
