Digital twin model development and validation for megawatt-scale alkaline water electrolysis

Journal of Renewable and Sustainable Energy, Год журнала: 2025, Номер 17(3)

Опубликована: Май 1, 2025

Electrolytic water hydrogen production systems are highly coupled and operate under complex hazardous conditions, making it challenging to conduct extreme experiments on physical systems, such as operating at less than 20% of the rated current. This study focuses a megawatt-scale alkaline electrolyzer develops its corresponding digital twin model. Operational data demonstrate that temperature, pressure, lye flow rate have significant impacts concentration in oxygen system voltage. The is crucial factor for safety, changes pressure or can lead notable variations concentration. Based operational data, multivariate nonlinear fitting empirical equations was performed using Matlab establish models voltage, Faraday efficiency, oxygen, electrolyzer. simulation results were analyzed validated theoretically, showing consistency with actual engineering data. model implemented controlled real time programmable logic controller. virtual mapping successfully achieved, providing an experimental platform future investigations into wide power fluctuations.
