What is Logn Term Energy Storage ?
LTES (Long Term Energy Storage) refers to technologies capable of storing energy for six hours or more , with some definitions extending to 10+ hours . These systems are essential for balancing the intermittent nature of renewable energy sources like solar and wind, ensuring a stable and reliable power supply even when generation is low. 🧪 Key LTES Technologies LTES technologies are categorized into five main types: Flow Batteries Store energy in liquid electrolytes. High scalability and long cycle life. Moderate efficiency (~70–80%). Compressed Air Energy Storage (CAES) Uses electricity to compress air stored in underground caverns or tanks. Air is released to drive turbines when power is needed. Efficiency: ~50–70%. Example: A 300 MW-class CAES facility in China using salt caverns. Liquefied Air/CO₂ Energy Storage Air or CO₂ is liquefied and stored under pressure. Re-gasifi...
