Liquid sensible heat storage materials

What are the different types of liquid sensible heat storage material?

The liquid sensible heat storage material can be majorly classified into 4 types, namely- water (fit for 25–90°C operating temperature range), mineral oils (operating temperatures up to 400°C), molten salts (varying between 200 and 900 °C operating range), and liquid metals and alloys (up to 1600°C operating temperature).

What is sensible heat storage?

Sensible heat storage is the form of heat transfer that involves a rise in temperature of a material, such as phase change materials (PCM). Common materials used for sensible heat storage include water, pebbles, rocks, concrete, and sand.

What is sensitive high temperature heat storage (shths)?

Sensible high temperature heat storage (SHTHS) raises or lowers the temperature of a liquid or solid storage medium (e.g. sand, pressurized water, molten salts, oil, ceramics, rocks) in order to store and release thermal energy for high-temperature applications (above 100°C).

What is the difference between sensible thermal storage and latent heat storage?

Sensible thermal storage includes storing heat in liquids such as molten salts and in solids such as concrete blocks, rocks, or sand-like particles. Latent heat storage involves storing heat in a phase-change material that utilizes the large latent heat of phase change during melting of a solid to a liquid.

What are the thermal properties of sensible heat storage materials?

The amount of stored heat is proportional to the density, specific heat, volume, and temperature variation of the storage materials. Basically, specific heat, density and thermal conductivity are the main thermal properties of sensible heat storage materials. Fig. 1 shows the main thermal properties of sensible heat materials.

Which materials are used in high-temperature sensible heat storage for electricity production?

Current implementation of high-temperature sensible heat storage for electricity production uses liquids (e.g., molten salts) and solids (concrete, rocks). 2.1.1.1. Liquid
