Several key technologies dominate the energy storage market:
Batteries: Lithium-ion batteries are the most common, but other types like solid-state and flow batteries are gaining traction. Flywheels: These store energy mechanically and are known for their long life and fast response times. Pumped Hydro: This involves storing energy in the form of water in an elevated reservoir. Thermal Storage: This method stores energy in the form of heat or cold, later converted back to electricity.
