CALMAC Stores Surplus Wind Energy in Ice Banks


While some green projects store the excess energy in a kinetic form, such as the fore-mentioned flywheels, others are inventing ways to use frozen water to collect surpluses from wind farms, which are more productive at night, when winds are stronger.

CALMAC, a NJ-based company, has a solution. Their IceBank energy storage tanks store renewable energy, like wind and or inexpensive clean efficient night-time electricity, in the form of ice for comfort cooling use during peak demand periods the next day.

Reducing the peak daytime demand for electricity can cut cooling costs 20-40%, source energy and emissions are reduced and construction of new power plants and transmission lines can be delayed or eliminated.
