| 摘 要： | 高温蓄热系统是太阳能热电站的关键子系统。基于金属氢化物的高温蓄热系统具有能量储存密度大、腐蚀性低和反应易于控制等优点,是很有发展潜力的蓄热技术。建立了金属氢化物高温蓄热系统的经济性分析模型,分析了不同类型的太阳能高温蓄热系统的成本,并计算得到了能量平均成本。初步估计,"蓄热反应器+储氢罐"金属氢化物蓄热系统的单位蓄热成本只有两熔盐罐蓄热系统的四分之一左右。大汉电站采用此种蓄热装置后,其能量平均成本降低了0.25元/kW.h。

| Abstract: | High temperature thermal energy storage system is a key component of the solar thermal power plant.High temperature thermal energy storage system using metal hydrides,which has advantages of high energy density,low corrosion and ease of control,is a truly attractive option in the long run.An economic analysis model of high temperature heat storage system using metal hydrides was established,and the cost per kWht and the levelized electricity cost of various thermal energy storage systems were obtained.The preliminary estimate suggested that the cost per kWht of the "Thermal energy storage reactor + tank" system is about a quarter of that of the two-tank molten salt system.When the DAHAN plant applies the novel system,the levelized electricity cost decreases by 0.25 yuan/kWh. |
