Ethanol water solution is a very important and common substance, but there are so few data available at present for describing the behaviour of the ethanol water solution at low temperatures. Ethanol water solution is important in that it that it has the following requirements: it is fluidic at low tempereratures and it provides a balance between the nature and environment. These features have made the ethanol solutions attractive for the purposes such as: utilizing low-temperature energy of LNG, rapid cooling of food-stuffs and use as a natural coolant. As the etnanol solution is a binary solution, it also can have a solid-liquid phase. The author has proposed this solid-liquid phase be used as a thermal energy storage substance because it has a superior fluidity.
