Solar energy is one of the promising renewable energy sources (RES) with a significant potential in SA, and Concentrated Solar Power (CSP) is a particularly promising solar technology due to its ability to provide dispatchable electricity with thermal energy storage (TES). This study presents an integrated energy model comprises of site suitability and techno-economic analyses for utility-scale CSP technology. The study investigates the potential and applicability of CSP technology for power generation in the western region of SA in two phases: site suitability analysis, and techno-economic assessment. The goal of phase one is to identify the optimal location of CSP plants by dint of combined Fuzzy-Boolean Logic and Analytical Hierarchy Process (AHP) using GIS tools. This novel approach provides a more comprehensive and robust analysis for evaluating suitable sites, accounting for uncertainty and ambiguity in decision-making and prioritizing criteria based on relative importance, thus making a novel contribution to the field. The analysis showed that 70 % of the province land is suitable for CSP deployment, with Makkah, Taif, Al-Khumra, and Turbah having the most suitable locations. In the second phase, two commercial CSP plants, Shams-1 and Noor III, were adopted in SA to evaluate the technical and economic feasibility of CSP plants adopted in five nominated sites that are located in the most suitable areas. The analysis showed that the lowest levelized cost of electricity (LCOE) for utility-scale CSP plants in Makkah province is 9.58 ¢/kWh for parabolic trough (PT) technology and 9.17 ¢/kWh for solar power tower (SPT) technology. Sensitivity analysis of TES showed that CSP plants with 8 hours of TES have the optimal configuration that produces electricity with lowest LCOE and highest capacity factor (CF). The overall findings of this study suggest that CSP is a viable and promising renewable energy (RE) technology for SA. The proposed site selection methodology can help to identify suitable sites for CSP plants, and the techno-economic analysis shows that CSP plants with TES can be cost-effective and reliable.INDEX TERMS Analytical hierarchy process, concentrated solar power, geographic information system, multi-criteria decision-making, site suitability analysis, techno-economic analysis.

“…It found out that when the turbine inlet temperature rises from 1,300 to 1,500 K, the levelized cost of electricity (LCOE) decreases from 188US$/MWh to 150US$/MWh. In AlKassem's research (AlKassem, 2021), it was shown that with the combination of GT, the total installed cost of solar field was lower than stand-alone TSP. Furthermore, a high field efficiency ranged from 53 to 59% was achieved, which leads to a high thermal-to-electric efficiency.…”

The wide utilization of solar energy is beneficial for the emission reduction of carbon dioxide. This paper proposes a novel power cycle system driven by solar energy, which consists of a recompression supercritical carbon dioxide cycle (RSCO2) and an ammonia-water cooling-power cycle (ACPC). The power system operates in a “self-production and self-sale” mode, which means that the refrigeration capacity produced by the ACPC is utilized to cool the main compressor inlet fluid of the RSCO2. The comprehensive energy and exergy analyses of the proposed novel system are presented. The effects of the six parameters on the system thermodynamic performance are evaluated, which are direct normal irradiation, the ammonia concentration of a basic solution, the pinch point temperature difference of an evaporator, the effectiveness of a recuperator, the pressure ratio of the RSCO2 and the molten salt outlet temperature. The results show that compared with the stand-alone RSCO2, the net power and energy efficiency of the proposed system are improved by 15.94 and 10.61%, respectively. In addition, the increasing ammonia concentration of the basic solution leads to the rise of the ACPC refrigeration output, and the inlet temperature of the main compressor can be declined to 32.97°C with the ammonia concentration of the basic solution of 0.88. Moreover, when the effectiveness of the recuperator in RSCO2 rises up to 0.98, the system energy and exergy efficiencies can reach their maximum value of 30.68 and 33.10%, respectively.

“…Increases in economic activity and general quality of life may be attributed to the doubling of global energy use in the recent year [1,2]. As the world's energy needs continue to rise at an alarming rate, it is crucial that we find ways to save energy and diversify our electrical energy sources to ensure long-term growth [3]. Between 2016 and 2030, it is expected that worldwide demand for primary energy will rise by almost 50% [4].…”

“…About 80% of the world's energy comes from these sources [5,6]. Natural gas combined cycles (NGCCs) are more efficient and provide a lower cost burden due to the incorporation of post-combustion carbon capture compared to direct-fired power systems [3]. Furthermore, concentrated solar power (CSP) utilizes the sun's thermal energy to generate electricity with little or no greenhouse gas emissions.…”

Enhancing the sustainability and diversification of Iraq’s electricity system is a strategic objective. Achieving this goal depends critically on increasing the use of renewable energy sources (RESs). The significance of developing solar-powered technologies becomes essential at this point. Iraq, similar to other places with high average direct normal irradiation, is a good location for concentrated solar thermal power (CSP) technology. This study aims to recover the waste heat from the gas turbine cycle (GTC) in the Al-Qayara power plant in Iraq and integrate it with a solar power tower. A thermoeconomic analysis has been done to support the installation of an integrated solar combined cycle (ISCC), which uses concentrated solar tower technology. The results indicate that the examined power plant has a total capacity of 561.5 MW, of which 130.4 MW is due to the waste heat recovery of G.T.s, and 68 MW. is from CSP. Due to the waste heat recovery of GTC, the thermal and exergy efficiencies increase by 10.99 and 10.61%, respectively, and the overall unit cost of production is 11.43 USD/MWh. For ISCC, the thermal and exergy efficiencies increase by 17.96 and 17.34%, respectively, and the overall unit cost of production is 12.39 USD/MWh. The integrated solar combined cycle’s lowest monthly capacity was about 539 MW in September, while its highest monthly capacity was approximately 574.6 MW in April.
