Summary:By offering promising solutions to two critical issues – the integration of renewable energies into energy systems and the decarbonization of existing hydrogen applications – green hydrogen production through water electrolysis is set to play a crucial role in addressing the major challenges of the energy transition. However, the successful integration of renewable energy sources relies on gaining accurate insights into the impacts that intermittent electrical supply conditions induce on electrolyzers. Despite the rising importance of addressing intermittency issues to accelerate the widespread adoption of renewable energy sources, the state-of-the-art lacks research providing an in-depth understanding of these concerns. This paper endeavors to offer a comprehensive review of existing research, focusing on proton exchange membrane (PEM) and alkaline electrolysis technologies operating under intermittent operation. Despite growing interest over the last ten years, the review underscores the scarcity of industrial-scale databases for quantifying these impacts. [Display omitted] •Dynamic features, e.g. event frequency and amplitude, affect efficiency and durability of alkaline and PEM electrolyzers.•Intermittent operation promotes electrolyzer decay, but literature lacks consensus and studies on alkaline technology.•Industrial-scale assessments of intermittency impacts are significantly lacking for both alkaline and PEM technologies.•Developing standardized methods is crucial to understand how intermittency affects electrolyzer efficiency and durability.
