Abstract

A Photovoltaic (PV) system integrated with Proton Exchange Membrane (PEM) water electrolysis offers an avenue for enhancing solar energy utilization and generating environmentally friendly hydrogen. Nevertheless, there has been limited focus on developing systems that can consistently produce hydrogen throughout the entire day, a critical aspect for the future widespread adoption of hydrogen. In this study, we established a PV-Battery-PEM electrolysis system for hydrogen generation. To achieve the objective of continuous hydrogen production, enhance energy efficiency, and minimize wasted sunlight, we introduced an energy management strategy (EMS). At the outset, we developed separate components, such as the PV system, the battery, and the PEM for hydrogen production, employing the Matlab/Simulink platform. Following this, we integrated these components into the comprehensive PV-Battery-PEM electrolysis system for hydrogen generation and confirmed the efficiency of the EMS through validation. Our analysis included an evaluation of energy efficiency under various operational scenarios, comparing systems with and without energy storage via batteries. The outcomes clearly indicate that the suggested EMS effectively achieves continuous hydrogen production throughout the entire day. Furthermore, when compared to systems without energy storage, systems equipped with energy storage batteries exhibit an energy efficiency improvement of 1.3 to 6.5% higher efficiency of hydrogen under similar operating conditions. This finding underscores the value of incorporating energy storage, as it enhances overall energy utilization and reduces the wastage of sunlight.
