This paper describes the performance of an integrated PV–wind hydrogen energy production system. The system consists of photovoltaic array, wind turbine, PEM electrolyser, battery bank, hydrogen storage tank, and an automatic control system for battery charging and discharging conditions. The system produced 130–140ml/min of hydrogen, for an average global solar radiation and wind speed ranging between 200 and 800W/m2 and 2.0 and 5.0m/s respectively. A mathematical model for each component in the system was developed and compared to the experimental results.
