Ice storage is the thermal energy storage using ice. It is practical because of the large heat of fusion of water. One metric ton of water (one cubic meter) can store 334 MJ or 317,000 Btu, 93 Wh, or 26.4 ton-hours. The original definition of a "ton" of cooling capacity was the heat to melt one ton of ice every 24 h.
