The electric power demand in recent years increases every year, and the demand during a day changes greatly according to the season and the time of the day. The difference in the power demand between the daytime and the nighttime is largest in summer, reaching about 2-3 times. Ice thermal storage has been employed as an effective means to level such a large difference in power demand. In this study, the use of aqueous solution of tetra-n-butylammonium bromide (TBAB) is proposed as a substitute for ice storage. TBAB solution changes its phase from liquid to solid, forming clathrate hydrate, at a temperature between 5 to 10℃ depending on the concentration. Measurements are made on the phase-change characteristics of TBAB solutions and the liquidus and the solidus are determined At the same time, the viscosity and the kinematic viscosity of TBAB hydrate are measured.
