Device from University of Hong Kong makes electricity from waste heat
  • Team of scientists from the University of Hong Kong have developed, and are patenting a technology for recovering electricity from low grade heat.
  • This type of heat is abundant, and available all around us, and a lot of it is essentially waste energy generated during industrial processes and energy consumption.
  • The new device, DTCC, is a bendable, stackable and low cost cell with graphene and polyaniline electrodes.
  • With 3.5% conversion efficiency, the device is better than any other thermo-electrochemical or thermo-electric system.
  • The team established a start-up to commercialize the technology.
