But it is a problem that a temperature of thermal storage reaction doesn't match with temperature of a heat radiation from sources such as industrial waste heat.
Most of heat sources from industrial waste heat accounts for more 600°C of such as steel industries or less 300°C of other industries.
It is required of developing new chemical thermal storage mediums corresponding to these heat source temperatures.
Mr. Ryu has been especially focused on and studied a magnesium hydroxide-based chemical thermal storage medium, which has a high capacity of thermal storage and a stability for transportation and storage, among chemical thermal storage mediums.

In the lecture, he introduced features of chemical thermal storage and demonstration experiments in recent years.
The chemical thermal storage is a method of thermal storage that uses chemical reaction, as its name suggests. It features a high energy density while it is reversible.

Among NEDO and other domestic companies, demonstration experiments of them are proceeding, and now is a phase of reporting concrete results of experiments.
Aiming to improve a performance of chemical thermal storage mediums, Mr. Ryu has been developing and evaluating magnesium hydroxide-based composite chemical thermal storage mediums, elucidating a reaction mechanism, and evaluating its durability.
The lecture was a great success.

This is a photo of Mr. Ryu after the lecture.
We have developed the CHARGEMAG^® PM-1 magnesium hydroxide thermal storage medium through a collaborative research with Mr. Ryu.
