Energialladusmeetodid, or energy storage methods, refer to technologies and systems used to capture energy produced at one time for use at a later time. These methods are crucial for stabilizing electricity grids, integrating renewable energy sources, and providing backup power.

One common method is electrochemical energy storage, primarily through batteries. Lithium-ion batteries are widely used due to their high energy density and relatively long lifespan, finding applications from portable electronics to grid-scale storage. Other battery chemistries, like lead-acid and flow batteries, also serve various purposes.

Mechanical energy storage encompasses several approaches. Pumped-storage hydroelectricity is a mature technology where water is pumped to a higher reservoir when electricity is abundant and released to generate power when needed. Compressed air energy storage (CAES) stores energy by compressing air into underground caverns or tanks, releasing it later to drive turbines. Flywheels store rotational kinetic energy in a spinning rotor.

Thermal energy storage involves capturing heat or cold for later use. This can include storing molten salts in concentrated solar power plants or using phase-change materials to absorb and release thermal energy.

Chemical energy storage converts electrical energy into chemical energy, often through electrolysis to produce hydrogen. This hydrogen can then be stored and used in fuel cells to generate electricity, or as a fuel itself.

The choice of energy storage method depends on factors such as capacity, duration, efficiency, cost, and environmental impact. Each method plays a role in building a more resilient and sustainable energy infrastructure.
