Underground Thermal Energy Storage
The main thermal storage types, sensible, latent, and thermochemical, are covered. A focus is placed on underground thermal energy storages, which normally are sensible storages, as they can store both hot and cold energy in the ground and thus are often integral to geothermal energy systems. Common types of underground TES are described: soil

Aquifer Thermal Energy Storage | SpringerLink
ATES open-loop systems can offer increased energy efficiency and long-term cost savings over pump and dump systems and closed-loop systems by using an aquifer as a seasonal storage reservoir for waste or excess thermal energy generated in off-peak seasons or periods of low demand such as solar energy in summer months or cold air in winter months.

Thermal energy storage
The sensible heat of molten salt is also used for storing solar energy at a high temperature, [10] termed molten-salt technology or molten salt energy storage (MSES). Molten salts can be employed as a thermal energy storage method to retain thermal energy. Presently, this is a commercially used technology to store the heat collected by concentrated solar power (e.g.,
Assesment for optimal underground seasonal thermal energy storage
An optimal design for seasonal underground energy storage systems is presented. This study includes the possible use of natural structures at a depth of 100 to 500 m depth. Experience with high-temperature underground thermal energy storage was also obtained from the bedrock heat store in Luleå and the rock cavern in Avesta. In [14], the
Advances in Thermal Energy Storage Systems (Second Edition)
7.1. Introduction. Earth''s shallow subsurface provides a huge and natural potential for heat storage, which can be utilized to store temporarily low-grade thermal energy such as supplied from solar heat or waste heat during periods of low demand and to recover it later during periods of high demand for space heating and cooling purposes (e.g., Banks, 2008; Lee, 2013;
Advances in thermal energy storage: Fundamentals and
Renewable energy systems require energy storage, and TES is used for heating and cooling applications [53]. Unlike photovoltaic units, solar systems predominantly harness the Sun''s thermal energy and have distinct efficiencies. However, they rely on a radiation source for thermal support. TES systems primarily store sensible and latent heat.
The theoretical potential for large-scale underground thermal energy
The same is true on a national or even regional scale. Excepting smaller scale heat storage using phase change and other materials, which can be transported (Pielichowska and Pielichowski, 2014), thermal energy storage and retrieval in underground mines and aquifers must therefore focus on a local or regional scale. In consequence it is
A Comprehensive Review of Thermal Energy Storage
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. This paper is focused on TES technologies that provide a way of

Introduction to thermal energy storage systems
Thermal energy storage (TES) systems can store heat or cold to be used later, at different temperature, place, or power. The main use of TES is to overcome the mismatch between energy generation and energy use (Mehling and Cabeza, 2008, Dincer and Rosen, 2002, Cabeza, 2012, Alva et al., 2018).The mismatch can be in time, temperature, power, or
