Energianvarastointikohteet

Energianvarastointikohteet refers to the physical locations or systems where energy is stored. These can range from natural geological formations to man-made structures and technological devices. The primary purpose of these sites is to hold energy for later use, helping to balance supply and demand, improve grid stability, and facilitate the integration of renewable energy sources.

Common types of energianvarastointikohteet include batteries, which store electrochemical energy. Large-scale battery installations, often referred to as energy storage systems, are increasingly being deployed for grid-level applications. Another significant category is pumped hydro storage, where water is pumped to a higher reservoir and released through turbines to generate electricity when needed. This is currently the most widely used form of large-scale energy storage globally.

Other energianvarastointikohteet involve thermal energy storage, where heat or cold is stored, often for heating and cooling purposes or to capture waste heat. Compressed air energy storage (CAES) utilizes underground caverns or tanks to store compressed air, which is later released to drive turbines. Flywheels store kinetic energy in a rotating mass. Hydrogen storage is also gaining traction, where hydrogen is produced, stored, and then used in fuel cells or combustion to generate electricity. The selection of an appropriate energianvarastointikohde depends on factors such as capacity requirements, duration of storage, efficiency, cost, and environmental considerations.
