2. MECHANICAL ENERGY STORAGE SYSTEMS

Mechanical energy storage encompasses a variety of systems, primarily focusing on the conversion of mechanical energy into electricity. The most well-known technology in this realm is pumped hydro storage, regarded as the most established form of energy storage.

In pumped hydro storage, two water reservoirs are placed at different elevations. During periods of low energy consumption, surplus electricity is utilized to pump water from the lower reservoir to the higher one. When energy is needed, the stored water is released, flowing back down through turbines to generate electricity. This process exemplifies gravitational potential energy conversion into electrical form, demonstrating high efficiency and scalability.

Compressed air energy storage (CAES) reflects another significant mechanical energy storage method. In CAES systems, air is compressed and stored in underground caverns or above-ground tanks. When energy is required, the compressed air is released, driving turbines to produce electricity. This method highlights the versatility of energy storage solutions, catering to varying geographical and operational contexts while providing critical grid support.

3. THERMAL ENERGY STORAGE TECHNIQUES

Thermal energy storage represents a distinct category of energy management solutions, capable of storing energy in the form of heat. This technology is pivotal in balancing generation and consumption, particularly in power plants that rely on solar thermal processes.

Molten salt storage systems serve as a prime example; they can retain heat generated by solar collectors and release it during periods of low sunlight. This stored heat can be converted back into electricity through steam generation, showcasing a method that enhances the dispatchability of intermittent energy sources. Additionally, phase change materials (PCMs) are utilized for their ability to absorb, store, and release heat efficiently.

The primary advantage of thermal energy storage lies in its ability to operate effectively over long durations, facilitating seasonal energy storage solutions. By generating power during peak demand periods and reducing the need for fossil fuel generation, thermal storage technologies contribute to reducing greenhouse gas emissions and enhancing grid stability.
