日本のGX文脈において
日本は再エネ余剰電力の活用と水素社会実現を政策目標に掲げ、系統連系型水電解の動的運転は重要課題。本知見は国内実証・導入設計に資する。
In the global GX context
As global hydrogen strategies scale, understanding electrolyzer degradation under intermittent renewable input is critical for bankability and system design. This adds pilot-scale empirical evidence to a literature dominated by lab-scale or modeling studies.

📄 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 [1] [2] [3] [4].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 identifiedas 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.
