Heat to electricity conversion

Low-grade heat is abundantly available in the environment, in solar thermal and geothermal energy, and even in human body heat, which could be valuable for recycling and converting into electricity. For example, in the process of converting primary energy into useful energy, over 60% is discharged to the environment in the form of waste heat, which involves a vast amount of low-grade heat below 100oC. Low-grade heat recovery will significantly help reducing greenhouse gas emission and bring tangible economic and environmental benefits. Our team focuses on thermo-electrochemical technologies that can provide opportunities for engineering entropy change, electron transport, and heat transfer for efficient low-grade heat recovery.
