Abstract

Energy storage systems are increasingly recognized for their efficiency and practicality in supporting renewable energy integration. This project focuses on implementing a Compressed Air Energy Storage (CAES) system at the Mohamad Khaled Medical Center in Beirut, Lebanon. The medical center currently relies on 367 solar PV panels for daytime electricity and a diesel generator for nighttime power. The goal of this project is to replace the diesel generator with a CAES system that stores excess energy generated by the solar panels during the day, compresses air using this energy, and then releases the stored energy at night to power the center for 12 continuous hours. Theoretical calculations were done. The system was also simulated using MATLAB. The results show that the system meets the nighttime energy requirements of the center, reducing operational costs and fossil fuel use. The system as reported achieved an overall efficiency of about 58.6% with significant energy savings and lower greenhouse gas emissions. Analysis showed that a storage air tank of 220 m³ was adequate to hold the compressed air. while the selected compressor and turbine were adequate in providing constant energy output. The compressor takes about 1.08 hours to fully fill the tank with compressed air. In addition, the implementation of the CAES system is expected to result in economic and environmental advantages, making it a suitable alternative to the current diesel generator.
