6 FAQs about [Energy storage closing sequence]
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.
Do energy storage systems perform well with a suboptimal architecture?
It is possible for an energy storage system with a good storage technology to perform poorly when implemented with a suboptimal architecture, while other energy storage systems with mediocre storage technologies can perform well when implemented with superior architectures.
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.
What makes a successful energy storage system?
A successful implementation depends on how well the energy storage system is architected and assembled. The system's architecture can determine its performance and reliability, in concert with or even despite the technology it employs.
How long can energy be stored in a refrigeration system?
In principle the energy can be stored indefi nitely as long as the cooling system is operational, but longer storage times are limited by the energy demand of the refrigeration system. Large SMES systems with more than 10 MW power are mainly used in particle detectors for high-energy physics experiments and nuclear fusion.
What is the third class of energy storage?
The third class, the GWh class, will be covered in section 4.2.2. Besides time shifting with energy storage, there are also other ways of matching supply and demand. With a reinforced power grid, regional overproduction can be compensated for by energy transmission to temporarily less productive areas.
