“…Using a multi-effect distillation (MED), the efficiency and economy of restoring dissipated heat of a CSP-driven GT system combined with a Kalina cycle (GT/KC cycle) were researched by Rafat and Babaelahi. 28 They optimized the performance and cost metrics of the integrated unit by PSO (particle swarm optimization) method and improved the energy and exergy efficiencies of the system by 11.4% and 6.02%. Combining a CSP-driven S-CO 2 and MEDthermal vapor compression (TVC) desalination, Kouta et al 29 recruited regeneration and recompression operations in the power cycle to increase thermal efficiency by 6%.…”

Summary The unsophisticated configuration of plants with magnetohydrodynamic liquid metal and no dynamic parts has made them cost‐effective and sustainable compared to the turbine‐based types. This paper proposes an innovative liquid metal magnetohydrodynamic‐based system for electricity, cooling, and hydrogen production utilizing a parabolic solar unit and waste exhaust gases as renewable heat sources, a double effect absorption cooling cycle, and a proton exchange membrane electrolyzer. Hence, an environmentally‐friendly system is devised and analyzed thermodynamically towards a lower emission footprint. The results of the thermodynamic analysis reveal that 71.5 kW, 10.26 m3/day, and 834.9 kW, power, hydrogen, and cooling are produced by the designed unit, respectively, with exergy efficiency and energy utilization factor of 45.28% and 40.27%. Also, the overall destruction of the exergy is obtained 527.4 kW, the main cause of which is the receiver due to high heat loss to the environment. The output of the parametric study indicates that the energy efficiency of the present plant improves by reducing the biogas temperature or by increasing the effectiveness of the solution heat exchanger and mass flow rate of the magnetohydrodynamic stream.

“…These two modes have been optimally designed and evaluated based on 6E analysis. Rafat and Babaelahi 27 investigated a solar hybrid power plant's heat recovery by a Kalina cycle and desalination based on emergoeconomic and emergoenvironmenal methods. In the other study, Energy, Exergy, Exergoeconomic, Exergoenvironment, Emergoeconomic, and Emergoenvironment (6E) analysis of an innovative quadruple combined cycle coupled with the magnetohydrodynamic generator have been performed by Esmaeilzadehazimi et al 28…”

The high amount of solar energy as clean and sustainable energy has increased awareness in solar energy concentration, especially in integrated concepts. One of the best and promising hybrid configurations for converting solar energy into power is an integrated solar combined cycle system (ISCCS). In this study, conventional and advanced analysis tools for the ISCCS located in Yazd (Iran) have been investigated. In this paper, thermodynamic simulation, exergy, exergoeconomic, and exergoenvironmental analysis based on Life Cycle Assessment (LCA) have been performed. In addition, an emergy-based concept, including emergoeconomic and emergoenvironmental assessment, has been performed. In-depth analysis of exergy, exergoeconomic, and exergoenvironmental modelling, advanced exergy analysis based on endogenous/exogenous and avoidable/unavoidable parts have been done. In this regard, MATLAB code has been developed for thermodynamic simulation, exergy, exergoeconomic, exergoenvironment, emergoeconomic and emergoenvironment analysis. Furthermore, THERMOFLEX (commercial software) applied for thermodynamic simulation and verification. The Sankey diagram based on each analysis tool has been constructed. Furthermore, the priority of improvement based on each analysis has been identified. The thermal efficiency and net power generation of ISCCS are 48.25% and 419600 kW, respectively. It was obsereved that in most equipment, less than 10% of exergy destruction and cost and environmental impact rates were avoidable/endogenous.
