2. TYPES OF ENERGY STORAGE CONVERSION TECHNOLOGIES

2.1 MECHANICAL ENERGY STORAGE

Mechanical energy storage is one of the most translated forms of energy retention characterized primarily by its reliance on physical and engineering principles. Pumped hydro storage (PHS) represents the most prevalent method, where water is elevated to a reservoir using surplus energy, later released through turbines for energy generation when demand arises.

Additionally, compressed air energy storage (CAES) utilizes excess energy to compress air in underground caverns. When energy demand peaks, the stored air is heated and expanded to drive turbines, generating electricity. Both mechanical systems display significant potential for large-scale applications, demonstrating reliability and efficiency. Their primary advantage lies in long discharge durations, making them suitable for stabilizing energy grids in real-time situations.

2.2 CHEMICAL ENERGY STORAGE

Chemically storing energy involves capturing energy within bonds of molecules. Batteries, especially lithium-ion variants, have gained significant traction in this category. They convert electrical energy into chemical potential through electrochemical reactions, allowing for recharging and repeated cycles without substantial energy loss.

Beyond conventional battery technologies, flow batteries serve as a versatile alternative for large-scale applications, as they store energy in liquid electroactive materials contained in external tanks. This characteristic allows for a much greater energy capacity, making them well-suited for grid applications where energy demands fluctuate significantly. Emerging technologies such as hydrogen fuel cells also add to the diversification of chemical storage, as they generate electricity through electrochemical processes while being eco-friendly when utilizing renewable sources for hydrogen production.

2.3 THERMAL ENERGY STORAGE

Thermal energy systems are engineered to capture and store heat energy for subsequent use. Concentrated solar power (CSP) plants, for instance, employ mirrors to focus sunlight onto a fluid, creating steam which drives turbines. To enhance reliability, many use molten salts for thermal storage, allowing energy retention when the sun isn’t shining.

In addition, phase change materials (PCMs) are receiving attention for their ability to absorb and release thermal energy at specific temperatures, facilitating energy management in residential and commercial heating and cooling systems. These thermal systems provide more than mere energy storage; they enhance efficiency in energy consumption patterns and contribute to lowering operational costs through effective heat management.
