The principle of energy storage systems is to use different physical or chemical processes to convert electrical energy into other forms of energy, and then restore it when needed

Is electrical energy. According to the form of energy storage, energy storage systems can be divided into the following categories:

Mechanical energy storage: The use of mechanical motion or gravitational potential energy to store electrical energy, such as pumped storage, compressed air energy storage, flywheel energy storage, etc.

Electrochemical energy storage: Utilizing devices such as batteries or capacitors to store electrical energy, such as lithium-ion batteries, sodium sulfur batteries, lead-acid batteries, and supercapacitors

Capacitors, etc.

Electromagnetic energy storage: The use of magnetic fields or induction coils to store electrical energy, such as superconducting magnet energy storage, superconducting coil energy storage, etc.

Thermal energy storage: The use of heat or phase change materials to store electrical energy, such as hot water energy storage, ice storage, phase change materials, etc.

Chemical energy storage: The use of chemical reactions or synthetic fuels to store electrical energy, such as hydrogen energy storage, methanol manufacturing, etc.

Different types of energy storage systems have different characteristics and advantages and disadvantages, and need to be selected and optimized based on specific application scenarios and needs. commonly

Generally speaking, mechanical energy storage is suitable for large-scale long-term storage, but its efficiency is relatively low; Electrochemical energy storage is suitable for small-scale short-term storage

Survival, but with a shorter lifespan; Electromagnetic energy storage is suitable for high-power and fast response applications, but its cost is relatively high; Thermal energy storage is suitable for heating or

Refrigeration related applications, but the conversion process is complex; Chemical energy storage is suitable for applications related to hydrogen or other clean fuels, but technology
