A novel methodology to determine the safe operating regime for an offshore wind-integrated electrolysis system

The offshore wind-integrated hydrogen production system is a novel approach to producing green energy carriers and chemicals. Even with the significant environmental benefits of this approach, there are major questions and concerns regarding its safety. Understanding better how operational parameters can promote safer operations is necessary. This paper overcomes key aspects of this gap by developing a novel method to quantify the influence of operational parameters on the formation of hazardous operational environments. Focus is given to the risks associated with gas crossover. The critical operational parameters (e.g., membrane thickness, cathodic pressure, supplied power, and H₂/O₂ recombination constant) have been identified, and their contribution to leading a potential accident scenario is assessed. The proposed method enables monitoring the unsafe operational space—the combination of parameters and their synergistic effect is causing a potential scenario. The proposed method would be an important tool that facilitates remote process control and safe operation.
