What is Energy Storage?

Energy storage refers to the process of capturing energy produced at one time for use at a later time. The most common form of energy storage in the power sector involves storing electricity, often generated by renewable sources, to address supply-demand imbalances, enhance grid reliability, and improve energy efficiency. Energy storage systems (ESS) come in several forms, including batteries, pumped hydro storage, compressed air energy storage, and flywheels. Among these, battery energy storage systems (BESS) are the most widely adopted in Asia Pacific due to their scalability, cost-effectiveness, and ability to integrate with renewable energy sources.

Types of Energy Storage Systems

1. Battery Energy Storage Systems (BESS):

   • BESS are the most commonly used energy storage systems in the Asia Pacific region. They use electrochemical processes to store and release energy and are highly efficient in balancing power grids. Lithium-ion batteries dominate the market, though other technologies such as sodium-sulfur, flow batteries, and solid-state batteries are emerging.

2. Pumped Hydro Storage (PHS):

   • Pumped hydro storage is a mature and widely used form of large-scale energy storage. It involves using excess electricity to pump water to a higher elevation reservoir. When energy is needed, the water is released to flow downhill, driving turbines to generate electricity.

3. Compressed Air Energy Storage (CAES):

   • In CAES systems, excess electricity is used to compress air and store it in underground caverns or tanks. When electricity is required, the compressed air is released, passing through turbines to generate power.

4. Flywheels:

   • Flywheel energy storage systems store energy in the form of kinetic energy. A rotor spins at high speeds to store energy, which can later be converted back into electricity. Flywheels are mainly used for short-term storage and high power applications.

Drivers of the Asia Pacific Energy Storage Market
