Energatárolás, or energy storage, refers to the process of capturing and holding energy for later use. This can be achieved through various methods, each with its own advantages and limitations. The primary goal of energy storage is to balance supply and demand, improve grid stability, and facilitate the integration of renewable energy sources.

One of the most common forms of energy storage is batteries, which convert electrical energy into chemical energy and vice versa. Batteries are widely used in portable electronics, electric vehicles, and grid-scale energy storage systems. Other methods include pumped hydro storage, where water is pumped to a higher elevation during periods of low demand and released to generate electricity during peak times. Flywheels store energy in a rotating mass, while compressed air energy storage (CAES) uses compressed air to drive turbines when needed.

Thermal energy storage involves capturing heat during periods of low demand and releasing it during high demand. This can be achieved through various materials, such as molten salts, phase change materials, or water tanks. Chemical energy storage involves the use of chemical reactions to store and release energy, often using hydrogen or other fuels.

The choice of energy storage method depends on various factors, including the type of energy being stored, the required power output, the duration of storage, and the cost. As the demand for renewable energy grows, energy storage technologies are becoming increasingly important in ensuring a stable and reliable energy supply.
