Implementation of a lab-scale green hydrogen production system with solar PV emulator and energy storage system

The aim of this research is to review, design, model and implement a green hydrogen production system by means of renewable energy sources. The proposed system is divided into three different power conversion stages: (a) renewable input power source: Photo-Voltaic (PV) emulator, (b) energy storage system: Li-ion battery, and (c) load: Electrolyser. A 600W PV emulator is connected to a 60Ah-12V battery storage system via a Maximum Power Point Tracking (MPPT) DC-DC converter. It is then connected to a 300W electroyser through a 500VA-230V inverter. In conjunction with the proposed designed system, the system was modelled in MATLAB/Simulink alongside a lab-scale experimental setup. The results attained through the simulation and experiment were in a perfect match and the overall system efficiency was achieved as projected. The article's conclusion will help the new researchers to select a system that is sustainable for green hydrogen production.
