This study experimentally evaluates a commercial 55kW PEM electrolyzer under harsh dynamic on/off and fluctuating load conditions to assess flexibility, efficiency, and durability impacts. Harmonized test protocols were adapted to quantify effects on key performance indicators sensitive to intermittency. It provides rare pilot-scale quantitative evidence for designing green hydrogen systems that integrate intermittent renewables.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は再エネ拡大と水素社会実現を政策の柱とし、電解装置の柔軟運転は系統安定化と余剰電力活用に直結する。本知見は国内実証（NEDO等）や企業の水素導入計画における機器選定・運用設計に資する。
In the global GX context
As global disclosure frameworks (TCFD/ISSB) push for credible transition plans, empirical data on electrolyzer flexibility supports the technological feasibility of green hydrogen pathways. It informs the operational assumptions behind corporate decarbonization and renewable integration strategies.

📄 Abstract（原文）
International audience ; With its ability to decarbonize industrial activities and mitigate intermittency issues linked to the integration of renewable energies in the grids, green hydrogen holds very strong assets for accelerating the energy transition. This process can be achieved through electrolysis allowing the production of a clean and renewable hydrogen when the electrical source comes from a renewable energy, intermittent by nature, whilst most systems are currently designed to operate at nominal capacity and constant load. Current literature has shown that the intermittent operation of an electrolyzer necessarily implies losses on different performance aspects. Even though these issues have gained interest over the last decade, the behavior of electrolyzers subjected to such conditions has not been sufficiently investigated within the scientific community and few quantitative assessment of the associated impacts, especially at pilot/large scale, have been reported from current literature. This study aims at experimentally evaluating the ability of a commercial 55kW PEM electrolyzer to withstand harsh dynamic on/off and fluctuating load conditions and the impacts on the key performance indicators identified as the most sensitive to intermittency. Harmonized test protocols from [5] were used as a guideline and adapted to the specific needs of this case study.
