7.2.2.2 Underground Storage. Underground thermal energy storage (UTES) is also a widely used storage technology, which makes use of the ground (e.g., the soil, sand, rocks, and clay) as a storage medium for both heat and cold storage. Means must be provided to add energy to and remove it from the medium.
Tank thermal energy storage. Tank thermal energy storage (TTES) is a vertical thermal energy container using water as the storage medium. The container is generally made of reinforced concrete, plastic, or stainless steel (McKenna et al., 2019 ). At least the side and bottom walls need to be perfectly insulated to prevent thermal loss leading

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 [4] and power generation. TES systems are used particularly in buildings and in industrial processes.
As shown in Fig. 1 (b) and (c), a nighttime cold energy storage system (CESS) has an additional cold energy storage tank connected to chillers, unlike the conventional air conditioning system. During the off-peak period, the chiller charges the phase change material (PCM)-based CES tank, and cold energy is released during the
The cost of a hot water storage tank can vary depending on factors such as the size, material, and additional features. On average, a basic 40-gallon hot water storage tank can cost around $500, while larger tanks or tanks with advanced features can cost upwards of $2000. 6.
A tank thermal energy storage system generally consists of reinforced concrete or stainless-steel tanks as storage containers, with water serving as the heat storage
The principles of several energy storage methods and calculation of storage capacities are described. Sensible heat storage technologies, including water tank, underground,
Cryogenic cylinders, which serve industrial and medical purposes with larger capacities, range in price from $3,000 to over $20,000, depending on size and material. Bulk storage tanks, designed for large-scale storage and distribution of liquefied gases, span a wide cost spectrum from $10,000 to over $500,000.
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).
