Heat absorption energy storage technology

What is absorption thermal energy storage?

5. Conclusion and perspectives Absorption thermal energy storage is promising for the storage of solar energy, waste heat and etc. Due to its superior properties including high energy storage density and small heat loss during long-term storage, the absorption thermal energy storage has been extensively studied in the last few years.

What is heat storage technology (TES)?

TES is a heat storage technology that collects, stores and releases heat with relatively large capacity. This feature allows the feasible integration of TES with diverse energy systems such as solar energy, wind energy, geothermal energy and industrial waste heat. With the difference in storage mechanism, TES can be classified as SHS, LHS and TCHS.

What is an integrated absorption thermal storage system?

Integrated absorption thermal storage system with internal compressor and working pairs . The pair is stable at a temperature up to 160 °C, but it requires rectification. The viscosity is very high and the absorbate may decompose at 110 °C, but with the three steps an energy density of 180 kWh/kg could be achieved.

Can absorption thermal energy storage be integrated with absorption heat pump?

In the Royal Institute of Technology, Sweden, integrated absorption thermal energy storage with absorption heat pump based on KOH-H 2 O theoretically studied , and energy storage density of 220 kWh/m 3 could be obtained. However, KOH is harmful and highly corrosive material which might hinder its implementation in real applications.

What is single-stage absorption thermal energy storage?

Single-stage absorption thermal energy storage (SATES) Single-stage absorption thermal energy storage has currently investigated by many researchers due to its simple system and was developed with the aims of different applications including cooling, space heating, domestic hot water, and heat transformer , , , .

What is the role of working pair in absorption thermal energy storage?

Except for the thermodynamic and system integration aspects, working pair also plays an important role in the absorption thermal energy storage. Previously, different absorption materials have been used for absorption cycles including absorption heat pumps, absorption chillers, and absorption heat transformer.
