The lab takes on global environmental and energy problems through the power of chemistry.

AboutAbout the lab
Using heat and energy through chemistry.
The Ryu Lab aims to solve global environmental and energy problems, mainly from the standpoint of applied chemistry and chemical engineering.
Its research centers on developing chemical heat storage materials that make effective use of unused thermal energy such as industrial waste heat, and on developing energy carrier technologies for using new energy sources.
The research is mainly experimental, and the lab has also begun to pioneer new research approaches that use methods such as machine learning.
In lab seminars held once or twice a week, members report on their progress, present related papers, and read foreign-language books together.
Key terms
- Chemical heat storage
- A mechanism that stores and releases heat through chemical reactions. Heat is stored by a reaction that dries the material, and released when the material reacts with water.
- Energy carrier
- A substance that converts renewable energy into a form that can be transported and stored. Ammonia is one example.
- Thermobalance
- An instrument that continuously measures changes in a sample's weight while heating or cooling it.
ResearchResearch themes
The lab aims to solve global environmental and energy problems from the standpoint of applied chemistry and chemical engineering. Its work rests on two pillars: chemical heat storage materials for using unused heat such as industrial waste heat, and energy carrier technologies for using new energy sources, mainly renewable energy.
*Illustrative imageDevelopment of Chemical Heat Storage Materials
The lab develops materials for using unused thermal energy such as industrial waste heat. Using a thermobalance that can be supplied with water vapor, it tests the dehydration reaction that stores heat and the hydration reaction that releases heat, and examines the changes before and after the reactions with powder X-ray diffraction and infrared spectroscopy.
*Illustrative imageEnergy Carrier Technologies
The lab develops technologies for using new energy sources, mainly renewable energy. With a high-pressure thermobalance that uses an electromagnet, it can test the absorption and release reactions of ammonia storage materials even in a corrosive gas atmosphere.
