What are the different types of energy storage?

There are various types of energy storage systems that can store energy for later use. The most common type is mechanical energy storage, which includes technologies such as pumped hydroelectric storage and compressed air energy storage. Pumped hydroelectric storage involves using excess electricity to pump water uphill into a reservoir, which can then be released to generate electricity when demand is high. Compressed air energy storage works by compressing air and storing it in underground caverns, which can be released to generate electricity through a turbine. Other types of energy storage include thermal energy storage, which involves storing heat for later use, and electrochemical energy storage, which includes batteries and fuel cells that can store and release electricity. Additionally, there are also emerging technologies such as flywheel energy storage and hydrogen energy storage that offer potential solutions for storing energy in alternative forms.
