4 · 3. Thermal energy storage. Thermal energy storage is used particularly in buildings and industrial processes. It involves storing excess energy – typically surplus energy from renewable sources, or waste heat – to be used later for heating, cooling or power generation. Liquids – such as water – or solid material - such as sand or rocks

Liquid-cooling is also much easier to control than air, which requires a balancing act that is complex to get just right. The advantages of liquid cooling ultimately result in 40 percent less power consumption and a 10 percent longer battery service life. The reduced size of the liquid-cooled storage container has many beneficial ripple effects.
