Construction of the International Linear Collider (ILC) in Japan has been considered. Since a large-scale accelerator such as the ILC is a facility with huge power load, it is important subject to build a sustainable power system in the operation. The electric power supplied to an accelerator is dissipated into the air as thermal energy from the cooling tower at the end. The temperature of the waste heat is usually less than 60 ℃ and it has not been reused so far. The water vapor adsorption material HASClay composed of nano-sized clay has been recently developed. It has a heat storage capacity with a principle of energy transfer in the desorption of water vapor. It particularly has an excellent storage ability for low-grade heat (<100 ℃). In addition, the heat stored can be reused offline by transporting the material with a sealed container. Now it is possible to establish a new heat supplying service if we can recover it by the HASClay from not only the ILC waste, but also various sources in the area around the ILC. In this study, we have developed a new technology to utilize the low-grade heat with a portable container aiming to establish an offline heat transportation system.
