High temperature energy storage enterprise

What is high-temperature energy storage?

In high-temperature TES, energy is stored at temperatures ranging from 100°C to above 500°C. High-temperature technologies can be used for short- or long-term storage, similar to low-temperature technologies, and they can also be categorised as sensible, latent and thermochemical storage of heat and cooling (Table 6.4).

Why is high-temperature storage important?

High-temperature storage offers similar benefits to low-temperature storage (e.g. providing flexibility and lowering costs). However, high-temperature storage is especially useful for smart electrification of heating and cooling in industry, given that many industrial processes either require high temperatures or produce high-temperature heat.

What is a high temperature storage material?

The main technological innovation of the company relies on the developed high temperature storage material in the form of purposely produced pellets or bricks, with high heat capacity and thermal conductivity.

Why is thermal storage important in the heating industry?

In the heating sector, characterized by demand seasonality of the residential demand, or batch processes of the industrial demand, the thermal storage with proper duration is a key technology to decouple energy supply and demand, and accommodate their temporal mismatches.

What is thermochemical energy storage (TCES)?

Thermochemical energy storages (TCES) are the least developed technology with limited examples of commercial solutions or companies trying to bring the technology to market. More R&D is currently ongoing with different solutions being investigated up to TRL 5, particularly for long duration and seasonal energy storages.

How do TES technologies store heat?

Sensible TES technologies store heat by changing the temperature of the TES media. In this case, wide temperature differences between charge and discharge operation are important to maximize the TES energy capacity. Similarly, high density and high specific heat capacity are important characteristics for the selected TES media.
