Tohoku Univ. Technology: HEAT STORAGE MATERIAL AND METHOD FOR USING HEAT ENERGY :T21-164
Excellent energy density, reaction rate, and reversibility
In recent years, attention has been focused on the development of technologies for effective utilization of sustainable energy from the viewpoint of global environmental protection. It is desirable to construct a heat recovery system that effectively utilizes low-grade waste heat of 100 to 200ºC, which accounts for most of the waste heat from factories. To realize this, various heat storage materials have been proposed. However, as the heat absorption/release reactions generally involve large changes in the crystal structure, the slow reaction rates and irreversibility of the reactions have been challenging issues, especially in the low temperature range. The present invention makes it possible to provide a heat storage substance that can accommodate a large amount of heat even in a low temperature region of low-grade waste heat. The research revealed that the layered manganese dioxide, which has long been used as an electrode material in batteries, can repeatedly absorb and release heat by releasing and absorbing environmental water at a sufficiently rapid rate.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): Tohoku University, Hirosaki University, Iwate University, Akita University, Fukushima University, Yamagata University, Tohoku Gakuin University, Iwate Medical University, Fukushima Medical University, Aizu University, Miyagi University, Hokkaido University, Muroran Institute of Technology, and Showa Medical University.
