Energy Storage Systems

Definition

Energy storage systems are technologies that capture energy produced at one time for use at a later time, playing a crucial role in balancing supply and demand in energy systems. They help manage the intermittent nature of renewable energy sources, such as solar and wind, ensuring that excess energy can be stored and utilized when production decreases or demand increases. This capability is essential for integrating renewable energy with combustion technologies, facilitating a more reliable and efficient energy grid.
