English translation of low temperature energy storage system

Can thermal energy storage be integrated into low-temperature heating & high- temperature cooling systems?

The present review article examines the control strategies and approaches, and optimization methods used to integrate thermal energy storage into low-temperature heating and high-temperature cooling systems. The following are conclusions and suggestions for future research and implementation in this field:

What is thermal energy storage?

Thermal energy storage (TES) provides a potential solution to the problem. Such a technology is also known as thermal batteries or heat batteries, which can store heat at a high energy density. Thermal energy storage is generally much cheaper with a longer cycle life than electrochemical batteries.

What is the difference between latent storage and thermochemical storage?

Latent storage uses the phase change of a material to absorb or release energy. Thermochemical storage stores energy as either the heat of a reversible chemical reaction or a sorption process. Based on: (IRENA 2020b). Notes: EUR/kWh = euros per kilowatt hour; TES = thermal energy storage; TRL = technology readiness level.

What is cold thermal energy storage?

Cold thermal energy storage (TES) has been an active research area over the past few decades for it can be a good option for mitigating the effects of intermittent renewable resources on the networks, and providing flexibility and ancillary services for managing future electricity supply/demand challenges.

What are the different types of thermal energy storage systems?

Thermal energy storage (TES) systems can store heat or cold to be used later, at different conditions such as temperature, place, or power. TES systems are divided in three types: sensible heat, latent heat, and sorption and chemical energy storage (also known as thermochemical).

How does low-temperature TES work?

Low-temperature TES accumulates heat (or cooling) over hours, days, weeks or months and then releases the stored heat or cooling when required in a temperature range of 0-100°C. Storage is of three fundamental types (also shown in Table 6.3):
