PART – A
How the Energy storage system are classified?
Answer
Energy storage systems are primarily classified based on the form of energy stored: Mechanical (e.g., Pumped Hydro, Compressed Air, Flywheels), Electrical (e.g., Capacitors, Supercapacitors), Electrochemical (e.g., Batteries, Fuel Cells), Thermal (e.g., Sensible, Latent, Thermochemical), and Chemical (e.g., Hydrogen, Synthetic Fuels).
What is the importance of EES?
Answer
Electrical Energy Storage (EES) is vital for balancing supply and demand, improving grid stability and reliability, integrating intermittent renewable energy sources like solar and wind, and providing backup power during outages or peak load conditions.
