Thermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used at a later time for heating and cooling applications and power generation. TES systems are used particularly in buildings and in industrial processes.

A dark, flat roof can be 75°F (42°C) warmer than the outside air temperature. Painting a south-facing wall a light color can reduce the effective wall temperature by 20°F (11°C) compared with a dark wall. Walls and roof of a cold storage facility should be painted a light color or shaded from the direct sun.

1. Introduction. In recent years, energy consumption is increased with industrial development, which leads to more carbon dioxide (CO 2) emissions around the world.High level of CO 2 in the atmosphere can cause serious climate change inevitably, such as global warming [1].Under these circumstances, people may need more energy
It includes three main parts: a power generation system, an energy storage system, and a cooling system. The power generation system includes gas turbines. The energy storage system consists of electric energy storages (i.e., the lithium-ion battery) and cold energy storages (i.e., ice-based thermal energy storage). the
According to the Global Assessment Report (Ürge-Vorsatz et al., 2012), there are five energy services that accounted for 86% of primary energy use in buildings by end-use services in the United States in 2010, out of which 14%–15% was space cooling both in residential and commercial buildings (Fig. 20.1).Moreover, Fig. 20.2 shows that
For chilled water TES, the storage tank is typically the single largest cost. The installed cost for chilled water tanks typically ranges from $100 to $200 per ton-hour,12 which corresponds to $0.97 to $1.95 per gallon based on a 14°F temperature difference (unit costs can be lower for exceptionally large tanks).
