This work evaluates concepts of hybridizing the molten salt central receiver design to recover spilled energy in an effort to reduce the electricity cost. The hybridization is done using existing technologies requiring marginal improvements. A simplified assessment is done to arrive at a target cost of two spillage recovery system without changing the prevailing levelized cost of electricity (LCoE) from the reference solar power plant. The target cost of the spillage recovery system using feedwater heater panels is $49M, whereas for concentrated photovoltaic modules, it is $40M. Integrating such systems with the tower type receiver below the target price is expected to reduce the LCoE of the plant. However, project specific conditions and requirements may also play an important role and should be taken into consideration with a more detailed overall plant level study to determine the feasibility of the hybridization concepts in a specific project.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
