6 FAQs about [Analysis table of thermal energy storage characteristics]

What is thermal energy storage (TES)?

Thermal energy storage (TES) technologies are designed to store heat from a source to make it available for a subsequent use. Generally, TES can be divided into three typologies (Fig. 1): Sensible heat storage (SHS): heat is stored (or released) by increasing (or decreasing) the temperature of a solid or liquid material without any phase change.

What is thermal energy storage in district heating?

Thermal energy storage in district heating In general, TES systems used in DH systems are sensible heat storages. Water is used as thermal storage material in most cases except for borehole/aquifer underground storages and for pit storages with gravel or sand. Water is cheap, easy to handle and already used as heat transfer medium in DH systems.

What is a thermal energy system?

2.3 Application evaluation Thermal energy systems have seen widespread use in the district heating sector. These systems have been installed in many countries across Europe for two main purposes: a) buffer storage and b) seasonal storage. Generally, conventional designs for both storage types are at a high TRL.

Can thermal energy be stored in a heat storage media?

Thermal energy (i.e. heat and cold) can be stored as sensible heat in heat stor-age media, as latent heat associated with phase change materials (PCMs) or as thermo-chemical energy associated with chemical reactions (i.e. thermo-chemical storage) at operation temperatures ranging from -40°C to above 400°C.

What are the methodologies for Technology Assessment in thermal energy storage?

The methodologies for technology assessment have been developed within Annex 30 and applied to benchmark and development cases of thermal energy storage in applications.

What are the economic methodologies used in a thermal energy storage system?

The economic methodologies applied in this report have been adopted from Annex 29 in ECES. To evaluate the integration of a thermal energy storage system in a process, key performance indicators (KPI) are determined from storage system parameters that dictate performance and external factors that emerge from the integration.
