USE OF THERMAL STORAGES IN COGENERATION FOR BOTH ELECTRICAL AND THERMAL PURPOSES

The integration of thermal energy storage with cogeneration and photovoltaic (PV) systems offers an exciting way to boost energy efficiency and promote sustainability in today’s power networks. This thesis examines a hybrid energy system that connects a PV module to two thermal storage units—one for heat and the other for electricity—both linked to the grid. The system is designed with a high-temperature thermal storage unit to handle thermal applications, while a low-temperature storage unit is optimized for electrical output. The research begins by exploring current technologies and materials suited to these temperature ranges, followed by developing a detailed framework to simulate the system’s performance using modern modeling tools. Key performance indicators such as thermal efficiency, electrical output, energy savings, and material viability are carefully analyzed to assess the system’s potential. Early findings suggest that this dual-storage setup can improve energy usage, cut down on emissions, and reduce reliance on fossil fuels. The project also uncovers some challenges, particularly in selecting materials and fine-tuning system operations, which point to valuable directions for future research. By presenting a fresh approach to integrating cogeneration, thermal storage, and PV technologies, this work aims to contribute to the shift toward net-zero energy goals while also strengthening the resilience of power grids.
