Volume 2, Issue 8, 18 August 2021, 100540 Phase change materials (PCMs) having a large latent heat during solid-liquid phase transition are promising for thermal energy storage applications. However, the relatively low thermal conductivity of the majority of promising PCMs (<10 W/ (m ⋅ K)) limits the power density and overall storage efficiency.
The energy storage capacity of the limestone improves with increasing fluidization velocity in carbonation stage. As the fluidization velocity increases from 0.04 to 0.06 m/s, the attrition rate of the limestone after 5 cycles increases by 96%. Smaller particles show higher energy storage and attrition resistance during the cycles.
Limestone presents a good attrition resistance in energy storage under fluidization. High fluidization velocity mitigates pore-plugging of limestone for energy storage. Thermochemical energy storage of CaO/CaCO 3 system is a rapidly growing technology for application in concentrated solar power plant.
Considering the energy storage capacity and the attrition behavior, the carbonation of the limestone for CaL energy storage operated under 100% CO 2 at the fluidization velocity of 0.06 m/s is more feasible. Fig. 14 presents the energy storage performance of the limestone carbonated at Ucarb = 0.06 m/s during 20 CaO/CaCO 3 cycles.
The effect of the carbonation temperature on the energy storage performance of the limestone after 5 cycles is depicted in Fig. 7. As the carbonation temperature is raised from 800 to 850 °C, X1 and X5 of limestone increase by 6% and 10%, respectively.
The limestone operated at the fluidization state exhibits a higher cyclic energy storage capacity than that at the static (solid-like) state. Higher fluidization velocity significantly mitigates the pore-plugging and sintering of the limestone. 1. Introduction
