Investigation of Different Load Characteristics, Component Dimensioning, and System Scaling for the Optimized Design of a Hybrid Hydrogen-Based PV Energy System

The realization of a carbon-neutral civilization, which has been set as goal for the coming decades, goes directly hand-in-hand with need an energy system based on renewable energies (REs). Due to strong weather-related, daily, and seasonal fluctuations in supply REs, suitable storage devices must be included such systems. For this purpose, model featuring hybrid consisting hydrogen unit (for long-term storage) lithium-ion device short-term was developed. With proper design, can ensure year-round by using electricity generated photovoltaics (PVs). In that investigated, (H2) produced electrolyser (ELY) PV surplus during summer months then stored H2 tank. During winter, due lack power, is converted back into heat fuel cell (FC). While components are expensive, resource- cost-efficient layout important. Matlab/Simulink enabled balance analysis component lifetime forecast model, results extensive parameter studies allowed optimized created specific applications. covered different focal points. Several ELY FC layouts, load characteristics, scales, weather conditions, levels—especially winter variations heating demand—were investigated.
