Energy Storage Technology is one of the major components of renewable energy integration and decarbonization of world energy systems. It significantly benefits addressing ancillary power services, power quality stability, and power supply reliability.
The electromagnetic ES method defines the accumulation of energy in the form of an electric field or a magnetic field. A current-carrying coil generates ES based on the magnetic field. Practical electrical ESTs include electrical double-layer capacitors, ultra-capacitors, and superconducting magnetic energy storage (SMES).
However, in addition to the old changes in the range of devices, several new ESTs and storage systems have been developed for sustainable, RE storage, such as 1) power flow batteries, 2) super-condensing systems, 3) superconducting magnetic energy storage (SMES), and 4) flywheel energy storage (FES).
Energy Density: CES storage systems typically offer high energy density, allowing for long-duration storage and portability. Reversible fuel cells and synthetic fuels also provide considerable energy density but may have lower overall efficiencies due to energy losses during conversion processes.
There are two general approaches to the solution of these types of requirements. One involves the use of electrical devices and systems in which energy is stored in materials and configurations that exhibit capacitor-like characteristics. The other involves the storage of energy using electromagnets. These are discussed in the following sections.
Chemical energy storage systems, such as molten salt and metal-air batteries, offer promising solutions for energy storage with unique advantages. This section explores the technical and economic schemes for these storage technologies and their potential for problem-solving applications.
