Figure 9-4 shows the total thermal energy in water versus its absolute temperature. Notice the significant increase in energy as a pound of water changes from ice to water. This transition can also be viewed in reverse, as a large increase in "cold storage" as a pound of liquid water changes to a pound of ice.

Ice storage

Ice storage is becoming increasingly popular in the age of heat pumps and renewable heat sources. They store heat and cold and can thus compensate for fluctuations in supply and demand. This amount of energy, called crystallisation energy, is equivalent to warming water from 0°C to 80°C. A large amount of energy can therefore be stored in
