Hydrogen production from water electrolysis process is used worldwide as an alternative to conventional fuels. Using photovoltaic thermal system (PV/T) for electrolysis energy supply could be an attractive and innovative option. The PV/T systems are a genuine power production technology, providing simultaneously electricity and heat. In this paper, an attempt is made to investigate the possibility of hydrogen production from PV/T solar plant. Assessment of electrical and thermal performances of this plant is performed based on thermo–electrical dynamic model. Such model was developed taking into account energy balance equations and validated through an experimental data from PV/T power plant installed at the University of Catania, Italy. The results clearly show a good fitting between simulated and experimental results (RMSE% less than 7.00%, and R-squared more than 0.99). At 12 pm, the mean maximum electrical and thermal energy provided by the PV/T solar plant is found about 0.84 kWh/m2 and 0.548 kWh/m2 respectively. In terms of hydrogen production, a considerable amount of hydrogen about 60 ml/min can be provided.

Abstract
Hydrogen production from water electrolysis process is used worldwide as an alternative to conventional fuels. Using photovoltaic thermal system (PV/T) for electrolysis energy supply could be an attractive and innovative option. The PV/T systems are a genuine power production technology, providing simultaneously electricity and heat. In this paper, an attempt is made to investigate the possibility of hydrogen production from PV/T solar plant. Assessment of electrical and thermal performances of this plant is performed based on thermo–electrical dynamic model. Such model was developed taking into account energy balance equations and validated through an experimental data from PV/T power plant installed at the University of Catania, Italy. The results clearly show a good fitting between simulated and experimental results (RMSE% less than 7.00%, and R-squared more than 0.99). At 12 pm, the mean maximum electrical and thermal energy provided by the PV/T solar plant is found about 0.84 kWh/m2 and 0.548 kWh/m2 respectively. In terms of hydrogen production, a considerable amount of hydrogen about 60 ml/min can be provided.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
