Categorically, energy storage technology can be classified into two types based on the method of storage: physical energy storage and chemical energy storage [4]. Physical energy storage encompasses technologies such as pumped storage, compressed air energy storage (CAES), and flywheel energy storage.

Compressed-air energy storage (CAES) is a way to store energy for later use using compressed air. At a utility scale, energy generated during periods of low demand can be released during peak load periods. The first utility-scale CAES project was in the Huntorf power plant in Elsfleth, Germany, and is still operational . The Huntorf plant was initially developed as a load balancer for fossil-fuel-generated electricity

A new form of PSH, called Ground-Level Integrated Diverse Energy Storage (GLIDES) systems, pumps water into vessels full of air or other pressurized gases. As more water fills the vessel, it compresses the gases. When the grid needs electricity, a valve opens and the pressurized gas pushes the water through a turbine, which spins a
As renewable energy production is intermittent, its application creates uncertainty in the level of supply. As a result, integrating an energy storage system (ESS) into renewable energy systems could be an effective strategy to provide energy systems with economic, technical, and environmental benefits.

As the isothermal compressor tanks fill with water, a pump pressurizes the water. As the air pressure rises, compressed air is pushed into one of the compressed air storage tanks. Using compressed air, water is pushed into a hydropower turbine, which generates electricity.
About two thirds of net global annual power capacity additions are solar and wind.
