Summary: This paper introduces a new approach for estimating the levelized cost of energy (LCOE) by incorporating the shareholder internal rate of return (IRR) into the analysis. By conducting a comprehensive techno-economic evaluation on a CSP power plant in Spain, the study identifies key factors such as annual net electricity production, total investments, equity percentage, and operation and maintenance costs that influence the LCOE. Results from the sensitivity analysis highlight the importance of these factors in determining the LCOE and provide valuable insights for investment decision making in the CSP generation industry.

Summary: The current context of the climate emergency calls for the decarbonization of the energy sector through the adoption of renewable energy sources. Concentrating solar power (CSP) technology has emerged as a commercially viable alternative, although it is hampered by high production costs and the challenge of managing production during temporary variations in solar resource availability. This study proposes the hybridization of CSP technology with direct biomass combustion, presenting an innovative process scheme that deviates from traditional configurations. The techno-economic evaluation of this novel configuration in a small-scale power plant reveals the potential for a cost-effective and sustainable energy solution.

Summary: Advanced Geothermal Systems (AGS) generate electric power through conductive heat transfer from rocks using a closed-loop circuit. However, AGS is currently uneconomical due to its slow heat transfer rate compared to heat advection. The use of CO2 as the working fluid improves AGS performance, and there are optimal parameters that minimize AGS costs. Nevertheless, significant advancements in drilling technologies are necessary to make AGS cost-competitive.
