Abstract
The practical pioneering methodologies can be employed to improve the efficiency of energy systems. To attain the desired objectives in exergy and economic studies, original configurations alongside practical methodologies are sought after. In this research, an advanced multigeneration system involving liquid air energy storage and desalination system is designed. The system has the potential to generate a wide range of products to increase the preferences of the system both technically and economically. The system produces sodium hypochlorite, cooling, electricity, heating, hydrogen, and potable water. The results from the conducted research revealed that the system can generate 5901 kW electricity power while the round-trip efficiencies from energetic and exergetic prospects are 65.8 % and 59.6 %, respectively. The total EDR from the system is approximately 16 MW. The noteworthy outcomes from economic assessments revealed that the payback periods of the system with and without renewable energy-powered systems are 2.7 and 2.9 years, respectively. Combining chemical and thermomechanical energy storage systems with process facilities provides a cutting-edge subject matter. The integrated energy storage system with the desalination unit indicates that over the peak-shaving periods, auxiliary products can be produced while renewable energy systems charge the energy storage system.
