What is electrical energy storage (EES)?

Electrical Energy Storage, EES, is one of the key technologies in the areas covered by the IEC. EES techniques have shown unique capabilities in coping with some critical characteristics of electricity, for example hourly variations in demand and price.

Which components in electrical engineering can store energy?

There are two components in electrical engineering that can store energy: capacitors and coils. This chapter concentrated on discussing features of importance for energy storage: namely, the features of supercapacitors and superconducting coils.

How is thermal energy stored?

Thermal energy is stored solely through a change of temperature of the storage medium. The capacity of a storage system is defi ned by the specifi c heat capacity and the mass of the medium used. Latent heat storage is accomplished by using phase change materials (PCMs) as storage media.

How is energy stored in a turbine?

(e.g. porous stones) and used again during expansion in a turbine. In fl ywheel energy storage (Figure 2-4) rotational energy is stored in an accelerated rotor, a massive rotating cylinder.

How does the integrated storage system work?

The integrated storage system is designed to cover 100 % of the demand with the energy generated by the PV system during the summer. During the rest of the year a little additional energy has to be purchased from the grid.

What are the different types of energy storage systems?
