With a large capacity thermal storage system using phase change material (PCM), Concentrated Solar Power (CSP) is a promising technology for high efficiency of solar energy utilization. In a thermal storage system, a dual-media thermal storage tank is typically adopted in industry for the purpose of reducing the use of the heat transfer fluid (HTF). While the dual-media sensible heat storage system has been well studied, a dual-media latent heat storage system (LHSS) still needs more attention and study; particularly, the sizing of volumes of storage tanks considering actual operation conditions is of significance. In this paper, a strategy for LHSS volume sizing is proposed, which is based on computations using an enthalpy-based 1D model. One example of 60MW solar thermal power plant with 35% thermal efficiency is presented. In the study, potassium hydroxide (KOH) is adopted as PCM and Therminol VP-1 is used as HTF. The operational temperatures of the storage system are 390°C and 310°C, respectively for the high and low temperatures. The system is assumed to operate for 100 days with 6 hours charge and 6 hours discharge every day. From the study, the needed height of the thermal storage tank is calculated from using the strategy of tank sizing. The method for tank volume sizing is of significance to engineering application.

This work concerns the economic potential assessment of an innovative hybrid-cooling system for steam condensation in concentrated solar power plants. The system consists of an air-cooled condenser (ACC) working in parallel to a latent heat storage with phase-change material (PCM). The purpose of the hybrid system is to store some of the latent heat of steam condensation during the turbine operation and reject it at night, in order to shift a share of the cooling work and exploit the high diurnal temperature range of desert areas. System’s energy and economic performances are assessed by the parametric analysis of a theoretical case study, referred to an existing solar power plant and based on historical meteorological data. The analysis considers an ideal “perfect” PCM storage system, namely with no technological barriers, and different cost scenarios. The simulation campaign outcome indicates how the innovative solution can provide just a slight improvement of the plant performance, which is anyway significant in qualitative terms since the risk of breakdowns of turbine operation during the hottest summer days is avoided. It is remarkable that the introduction of the heat storage allows for a reduction of the ACC installed power. The economic feasibility of the proposed solution follows on mainly from the comparison between the investment cost increase —due to the PCM storage—and savings—due to reduction of the installed ACC modules. The hybrid-cooling system would be an attractive alternative to standard systems if the PCM storage cost could be contained by increasing the conductivity of the PCM material. As an alternative, a cheaper heat storage technology (e.g., a water thermocline) could be coupled to an indirect-cooling system.

This paper deals with an optimal design solar tower power plant. Special attention is focused on the central receiver system and heat storage materials. In order to get an effective power plant, a simple mathematical model to calculate the solar energy, concentrated on the solar receiver during one year, is developed. The model can predict the delivered energy in dependence on the arrangement of the heliostats and the height of the solar receiver. By using an optimizer, a plant of 5 MW power is optimized in order to produce a maximum of electrical energy during the year on the prescribed area. On the basis of analysis of heat storage materials, KNO3, acting as phase change material (PCM), is shown to be suitable for heat storage from the thermal, physical, kinetic, chemical, and economic point of view.
