Energiastoraget, often referred to as energy storage, is the capture of energy produced at one time for use at a later time. This process is essential for balancing supply and demand in energy systems, particularly with the increasing integration of renewable energy sources like solar and wind, which are intermittent in nature. Without effective energy storage, the electricity generated by these sources can be lost if not immediately consumed.

The technologies used for energy storage are diverse and range from mechanical systems to chemical and electrical methods. Common examples include batteries, pumped hydro storage, compressed air energy storage, and flywheels. Batteries, particularly lithium-ion technology, have seen significant growth due to their application in electric vehicles and grid-scale storage. Pumped hydro storage, one of the oldest and most established forms, utilizes reservoirs at different elevations to store potential energy. Compressed air energy storage (CAES) involves compressing air into underground caverns or tanks and releasing it to drive turbines when needed.

The applications of energy storage are widespread. On a grid level, it helps to stabilize electricity prices, improve reliability by providing backup power during outages, and facilitate the integration of renewable energy. For consumers, it can reduce electricity bills by allowing them to store energy generated from rooftop solar panels for use at night. In transportation, batteries are the cornerstone of electric vehicles. The development and deployment of efficient and cost-effective energy storage solutions are considered critical for a sustainable and decarbonized energy future.
