Parametric analysis and new performance correlation of an innovative system for green hydrogen, oxygen, heat, and electricity production: Application in Pau

Résumé

Multi-generation systems powered by renewable energy sources are positioned as promising solutions to reduce the carbon footprint. This work proposes and analyses an innovative system capable of simultaneously gener- ating green hydrogen, electrical energy, and thermal energy. The system combines a proton exchange membrane (PEM) electrolyser with photovoltaic thermal (PVT) collectors using heat pipes (PVT/HP). A statistical model was developed to estimate the electrical and thermal energy outputs of the PVT collectors, and the generation rates of green hydrogen and oxygen produced by the PEM electrolyser. The study examines the impact of solar radiation intensity, ambient temperature, mass flow rate, and the number of heat pipes on the system’s per- formance. A Multiphysics approach was implemented, combining the modelling of radiative, conductive, and convective heat transfers within the PVT collectors with the PEM electrolyser model, while applying the response surface methodology (RSM). The model demonstrates remarkable accuracy, with coefficients of determination of 0.9792, 1, 1, and 1 for thermal energy, electrical power, and hydrogen and oxygen production rates, respectively. The results indicate that under a temperate oceanic climate (Pau, France), the system achieves a maximum electrical power of 3623 W in July, while January records the lowest thermal energy production, at 1125 W. Hydrogen and oxygen production rates also peak in July, reaching 0.9984 g/min and 7.924 g/min, respectively, compared to 0.422 g/min and 3.343 g/min in January. This work highlights the potential of integrated renewable energy systems for sustainable energy production and provides valuable insights for optimizing performance in similar climatic regions.
