Abstract:
The coupling of solar photovoltaics (PV) and electrolysers represents a promising technology for the production of hydrogen in a way that is both ethical and sustainable for the environment. While PV and electrolyser technologies are well-established, the efficiency of such systems still poses great challenges due to the high variability of solar radiation. These fluctuations directly impact the power output of solar PVs, affecting the electrolyser’s performance. In order to overcome the challenges associated with solar radiation variability, an efficient coupling between the solar PV and the electrolyser is essential to ensure optimal hydrogen production. The coupling of this system entails the use of suitable power conversion devices, such as DC-DC converters, which can help to regulate both the current and the voltage that is being supplied to the electrolyser. Depending on the size of the system, there are different converters that can be used, such as a buck-boost converter. Its operation involves the conversion of the input voltage to either a higher or lower output voltage, depending on the requirements of the electrolyser. By adjusting the duty cycle of the converter, the buck-boost converter can efficiently manage the power flow and stabilize the voltage and current levels, enhancing the performance of the electrolyser. In this paper we undertake a comprehensive analysis of a solar PV-electrolyser system by utilizing MATLAB/Simulink. The main objective of this study is to evaluate the efficiency of this system, particularly in relation to hydrogen production. To achieve this, a buck-boost converter within the simulation model was included. Through the simulation, we analyze the efficiency of the system under varying case scenarios. The simulation offers a comprehensive understanding of the solar PV-electrolyser system's performance and its potential for efficient hydrogen production.
