Abstract
This work presents a comprehensive comparative analysis of second-generation (Gen2) and third-generation (Gen3) concentrated solar power (CSP) technologies. The study focuses on their techno-economic performance across three diverse geographical locations: Carrera Pinto, Patache, and Santiago, in Chile. The assessment involves detailed modelling of key subsystems, including the central receiver and power block, considering daily variations and the effects of weather conditions. The results reveal that Gen2 CSP technology can achieve competitive levelized cost of energy (LCOE) values when incorporating projected cost reductions. Notably, Gen3 CSP, using solid particles as the heat transfer medium, exhibits substantial advantages due to its operation at higher temperatures (~800°C). The study also underscores the influence of local climatic conditions on CSP performance. The findings suggest that improved cost projections can render previously less attractive sites, such as Patache and Santiago, viable options for CSP deployment, underscoring the evolving landscape of renewable energy technologies.
