Summary: The eccentricity of shell and tube heat exchanger (STHE) has a significant impact on the performance of thermal energy storage (TES) systems with phase change materials (PCM). In this study, it was found that eccentric charge performance is better than concentric arrangement, with optimal eccentricities of 6 and 10 for single-tube and multi-tube systems, respectively. By optimizing the eccentricity, the total melting time of the four-tube, three-tube, two-tube, and single-tube systems were reduced by 63%, 63%, 60%, and 54% compared to concentric cases, respectively. Additionally, the total solidification time of the single-tube case was reduced by 56%, 52%, and 49% compared to the four-tube, three-tube, and two-tube cases.

Summary: In this study, a high temperature thermal storage system using a hybrid of phase change material and graphite as the storage materials was designed and evaluated for its applicability as a utility-scale Carnot battery. The system consists of an externally heated liquid sodium tank as the heat transfer fluid and a graphite storage medium sandwiched by two phase change materials. The cost of the system was found to be comparable to other storage technologies at $476/kWh(e), but could be reduced to $321/kWh(e) if the cost of graphite and/or steel could be reduced.
