Energy systems play a key role in harvesting energy from various energy sources and converting it into the energy form required for applications in various sectors such as utilities, industry, buildings and transportation.
Energy sources like fossil fuels can be used to provide energy based on customer demand and ready to store when not needed. But other energy sources, such as solar and wind, need to be collected when available and stored until needed.
The application of energy storage systems can provide energy systems with various advantages, such as allowing an increased share of renewable energy supply and better economic performance.
In addition, energy storage is very important for power systems, enabling load balancing and peak shaving, frequency regulation, and improving power quality and reliability.
Energy storage systems have been used for centuries and have undergone continuous improvements to reach the current level of development. So far, some storage types have been developed relatively maturely, but some still need to be developed and perfected.
There are different types of energy storage systems for different application scenarios, including electrochemical energy storage and battery energy storage, thermal energy storage, thermochemical energy storage, flywheel energy storage, compressed air energy storage, pumping energy storage, magnetic storage energy, chemical energy storage, and hydrogen energy.
