Energy Storage

Thermal Storage. Thermal energy storage draws electricity from the grid when demand is low and uses it to heat water, which is stored in large tanks. When needed, the water can be released to supply heat or hot water. Ice storage systems do the opposite, drawing electricity when demand is low to freeze water into large blocks of ice, which can ...
