Title: Thermal energy storage system

Abstract

A thermal energy storage (TES) component includes a shell having first and second ports, and at least a first set of thermally conductive sealed containers that contain a TES media for storing thermal energy. A first set of sealed tubes containing a first TES media are in a first section of the shell, and a second set of sealed tubes containing a different TES media are in a second section of the shell. Electric heating elements are immersed in at least some of the tubes, and may extend only from one end of the tube. In some embodiments more than one heating element is immersed in the TES media and positioned to enhance convective flow. In some embodiments electric heating elements are disposed externally on the sealed tubes. Some tubes are tapered or frustoconical, with heating elements provided in a larger-diameter portion of the tubes.
