Solid high temperature energy storage technology

What are solid state sensible thermal energy storage systems?

Solid state sensible thermal energy storage (TES) systems have emerged as a viable method of heat storage especially with the prospect of using natural stones as heat storage media which are cheap, locally available, and harmless to the environmental.

What is high temperature sensible thermal energy storage?

Definition of limit temperatures of the proposed subdivision scale for operating temperature ranges of energy storage systems , , , . Analogously, sensible thermal energy storage in the high temperature range can be called high temperature sensible thermal energy storage or HTS-TES.

What is the performance of heat storage technologies?

Performance of heat storage technologies and their projections . Sensible heat storage is the cheapest technology and as such it is the most commonly adopted among the other types of TES and currently it is used mainly for residential hot water tanks, space heating and as heat storage systems (molten salt) for solar thermal power plants .

Which solid materials exhibit good thermal properties for heat storage applications?

Other solid materials found to exhibit good thermal properties for heat storage applications include, cast iron, cast steel and fire bricks. Different ranges of values of thermophysical properties for various solid materials being considered for heat storage were obtained and summarised in Table 5.

What is thermochemical heat storage?

Thermochemical heat storage is a technology under development with potentially high-energy densities. The binding energy of a working pair, for example, a hydrating salt and water, is used for thermal energy storage in different variants (liquid/solid, open/closed) with strong technological links to adsorption and absorption chillers.

What is sensitive heat storage?

Sensible heat storage is a mature technology. Different storage media (SM) are required for different temperature ranges. Water is used for temperatures up to 200 °C. For higher temperatures, SM in liquid state like thermal oil (up to 400 °C), molten salts (130–600 °C), or solid materials like rocks or ceramics (100–1300°C) are considered.
