2.2 MECHANICAL STORAGE

Mechanical energy storage systems, which include technologies like pumped hydro storage and flywheels, offer additional alternatives. Pumped hydro storage accounts for a significant portion of global energy storage capacity. This method leverages gravitational potential energy, integrating a pair of reservoirs at different elevations, to store and release energy. During off-peak times, surplus energy is used to pump water uphill. When energy demand spikes, the stored water is released, generating electricity through turbines.

Flywheels, another notable mechanical storage technology, store energy in a rotating mass. As an efficient way to provide short bursts of power, flywheels can rapidly absorb and release energy. By leveraging laws of physics, these systems can achieve high cycle times and long operational lifespans, thus serving both grid stability and short-term energy imbalances efficiently.

3. THERMAL STORAGE

3.1 HEAT STORAGE SYSTEMS

Thermal energy storage focuses on harnessing heat generated from various processes. These systems allow for the storage of excess thermal energy and its later use in electricity generation or as direct heat. Phase change materials (PCMs) serve as the core of many thermal storage solutions, absorbing heat and transitioning between solid and liquid states at specific temperatures.

By utilizing PCMs, thermal energy can be stored effectively, reducing the need for additional heating during peak hours. This is especially useful in applications such as district heating and cooling systems. Implementing thermal storage is crucial in balancing energy supply and demand, providing a sustainable approach to managing energy flows, especially in regions where direct electricity generation from renewable sources might be inconsistent or limited.

3.2 SOLAR THERMAL STORAGE

Solar thermal storage systems capture solar energy in thermal form, providing a reliable energy source even during non-sunny periods. These systems often incorporate large tanks filled with water or molten salts, which can store heat for extended durations. The retrieved heat can be employed for both electricity generation through steam turbines and for heating applications.

The concentration of solar power (CSP) technologies exemplifies the integration of thermal storage within solar energy frameworks. CSP systems not only generate electricity during sunlight hours but, through effective storage mechanisms, can provide power after sunset, thus addressing the intermittency associated with solar energy generation.

4. ROLE IN RENEWABLE ENERGY INTEGRATION
