Abstract

© 2023 Elsevier LtdThe current article develops a conceptual study and simulation of a multigeneration process based on the solid waste-incineration power plant coupled with a field of solar thermal system. The considered multi-generation layout is comprised of a municipal solid waste incineration unit, a steam cycle, the concentrating solar thermal collectors (based on the parabolic trough collectors), an organic steam cycle, a desalination unit (based on a reverse osmosis unit), and a hydrogen fuel production unit (based on the alkaline electrolyzer). The planned multi-generation process can produce electricity, thermal energy, hydrogen energy, and freshwater. The paper addresses a multi-generation process with a new structure, configuration and relationships between the units of the process. A comprehensive thermodynamic-conceptual, exergoeconomic and sustainability evaluations of the multi-generation process is developed. The findings indicated that the process can achieve energetic and exergetic efficiencies of 21.72% and 16.94%, respectively. Moreover, approximately 42.2 MW of the exergy is destroyed by the process. In such a context, the total cost and sustainability index of the proposed process were 653.03 USD/h and 1.72, respectively. It was also found that the Levelized Cost of Energy of the system was almost 0.072 USD/kWh. A parametric analysis is also provided to identify influencing factors.
