Effective utilization of waste heat from biomass power plants has become very important to reduce CO_2 emissions. However, it is difficult to use waste heat on-site or very nearby. This is so that there is too much waste heat to use as heating and cooling applications on the site. We need a method to transport waste heat to heating and cooling applications of other sites. Kobe Steel Ltd. and Kobelco Eco-Solutions Co., Ltd are developing latent thermal energy storage equipment for such a transport system. The erythritol of phase change material (PCM) and direct contact heat transfer technology are being used for this equipment. Direct contact heat transfer technology is a thermal energy storage method of contacting heat medium to PCM directly. The advantages are high performances of heat input and heat output and light weight equipment without the need for a heat exchanger. Therefore, in this paper, we report on a study of a new model of thermal storage cassette, for the target performance of maintaining fixed heat output at a temperature of 90℃ for 8 hours, and performing 90% or more of heat recovery by 4t pilot-scale thermal storage cassette.
