Technoeconomic Impacts of Storage System Design on the Viability of Concentrated Solar Power Plants

•Cost of seven sensible and/or latent high temperature thermal storage systems for concentrated solar power technoeconomically evaluated•Costs ranged from $22.11/kWhtto $57.60/kWht•2-tank molten chloride was the lowest cost storage but when integration costs added a 2-PCM hybrid system was more economically feasible•System costs could be reduced by decreasing the turbine inlet temperature or improving the material properties•A full system analysis is required when comparing differing storage technologies if a fair and reliable comparison is to be made
