Electrolyzers, the cornerstone of green hydrogen production, are undergoing significant advancements through intense research and innovation efforts. The focus is on enhancing efficiency, minimizing performance degradation over time, and streamlining development processes. An upcoming free online event, AVL SIMpulse, aims to highlight the transformative power of simulation tools in electrolyzer technology development. By allowing precise modeling of components and optimizing system performance, engineers can enhance stack designs, predict system behavior, and avoid costly trial-and-error approaches. This event emphasizes the importance of a well-structured development process starting with plant models to facilitate efficient system design and operation. By tackling efficiency and durability challenges of both PEM and Solid Oxide electrolyzers, the event promises to ensure the sustained high performance of these systems. Virtual Twins, a key concept in the event, offer the opportunity to mirror real-world behavior, thereby expediting innovation and reducing engineering workload. Furthermore, the integration of stack-level processes with the Balance-of-Plant enables a comprehensive understanding of internal mechanisms, providing invaluable insights that are typically hard to obtain through conventional means. Whether in the realm of developing cutting-edge electrolyzers or optimizing existing setups, the event aims to equip participants with the necessary knowledge and tools to excel in the constantly evolving field of hydrogen innovation.
