Introduction to Energy Storage
Energy storage is a crucial technology that plays a vital role in modern energy systems. It involves the capture and storage of energy for later use, addressing the intermittent nature of renewable energy sources such as solar and wind power. By storing excess energy during periods of low demand and releasing it when demand is high or when renewable sources are not generating, energy storage helps balance the grid, improve energy efficiency, and enhance the reliability and stability of power supply.
There are various types of energy storage technologies, including battery energy storage systems (BESS), pumped-storage hydroelectricity, thermal energy storage, and flywheel energy storage. Among these, BESS has gained significant popularity in recent years due to its high energy density, fast response time, and scalability.
