2. TYPES OF ENERGY STORAGE

2.1 MECHANICAL STORAGE

Mechanical storage encompasses methods like pumped hydro storage and flywheels. Pumped hydro storage, perhaps the most established form of energy storage, involves moving water between two reservoirs at different elevations. During periods of excess energy generation, water is pumped to a higher level, effectively storing energy in the form of gravitational potential energy. When there is a need for electricity, the water is released back down, driving turbines to produce power.

In addition, flywheels utilize kinetic energy, involving a rotating mass that stores energy mechanically. When energy input exceeds output, the flywheel accelerates, storing energy. During energy demand spikes, the flywheel’s rotational energy is converted back into electrical power. This storage form is particularly noted for its high efficiency and rapid response capabilities, making it ideal for grid stabilization and immediate load balancing.

2.2 THERMAL STORAGE

Thermal storage systems leverage the principles of heat retention to store energy. These systems can absorb and store thermal energy for later use, often utilizing materials like water or concrete. In one prominent method, molten salt is used in concentrated solar power plants. The salt retains significant thermal energy during sunny periods and releases heat to generate steam for electricity production on demand, even when sunlight isn’t available.

Another example of thermal storage involves ice storage systems. During off-peak hours, excess electricity is utilized to freeze water into ice. When demand surges during the day, chilled water systems draw upon the ice, providing cooling without the need for high electricity consumption. This approach effectively shifts energy usage patterns, reducing peak load on the grid and optimizing overall energy resource allocation.
