Experimental studies on the charging performance of single-tank single-medium thermal energy storage

Abstract

This paper presents an experimental evaluation of the performance of a thermal storage tank during the charging process using a molten salt as the thermal storage medium. This study was carried out as basic research on molten salt thermal energy storage, and the charging performances of two types of molten salt (HITEC, Solar salt) were empirically assessed. The detailed structure of a storage tank for thermocline was developed for the charging process, and the applicability of the single-tank structure was verified. Single-tank thermal storage data, which is only available in a limited manner in the literature, was experimentally obtained, thus, this study is expected to contribute to the basic design of the single-tank method in the near future.
