Common chip types for energy storage power supplies

What are the different types of energy storage?

One of the main functions of energy storage, to match the supply and demand of energy (called time shifting), is essential for large and small-scale applications. In the following, we show two cases classifi ed by their size: kWh class and MWh class. The third class, the GWh class, will be covered in section 4.2.2.

What technologies are needed to save energy?

Storage and use of hydrogen, and generation and use of synthetic natural gas for storing electricity, are relatively new technologies; improvements particularly in reliability and cost are needed.

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 EES technologies can be used in a large-capacity battery system?

Several mature EES technologies, in particular FES, DLC and battery systems, can be used in these ranges. PHS is the only currently feasible large-capacity EES for medium discharge times; further development in CAES is expected. Suitable locations for large PHS and CAES systems are topographically limited.

What types of energy systems can be used for power generation?

In addition to fuel cells, gas motors, gas turbines and combined cycles of gas and steam turbines are in discussion for power generation. Hydrogen systems with fuel cells (less than 1 MW) and gas motors (under 10 MW) can be adopted for combined heat and power generation in decentralized installations.

What are the applications of compressed air energy storage?

The main applications are for energy management via time shift, namely non-spinning reserve and supply reserve. Compressed air (compressed gas) energy storage (Figure 2-3) is a technology known and used since the 19th century for different industrial applications including mobile ones. Air is used as storage
