What is energy storage?
Energy storage is the capturing and holding of energy in reserve for later use. Energy storage solutions include pumped-hydro storage, batteries, flywheels and compressed
Key functions in terms of energy storage include: Balancing supply and demand, ensuring that there is always electricity available when needed. Integrating intermittent energy sources, such as solar and wind, by storing excess energy during periods of high generation and strategically releasing it when production is limited.
Energy can also be stored by making fuels such as hydrogen, which can be burned when energy is most needed. Pumped hydroelectricity, the most common form of large-scale energy storage, uses excess energy to pump water uphill, then releases the water later to turn a turbine and make electricity.
Energy storage systems are devices capable of carrying out these transformations in an efficient and controlled way, allowing to better manage energy supply and demand nationwide. What is an energy storage system? An energy storage system is a device or set of devices that can store electrical energy and supply it when needed.
An energy storage system consists of three main components: a control system, which manages the energy flow between the converter and the storage unit. The operation of an energy storage system depends on the type of technology used, which can be chemical, electrochemical, mechanical, thermal, or electromagnetic in nature.
