Description

A materials scientist at City University of Hong Kong (CityU) and his research teams are advancing the frontiers of renewable energy research with two significant inventions that tackle the looming energy crisis.

Led by Professor He Jr-hau from the Department of Materials Science and Engineering, the inventions include the development of a novel wave energy device that generates energy while reducing carbon dioxide (CO2), as well as a new photoelectrochemical system that will increase the efficiency of solar-to-hydrogen energy conversion by two-fold and at half the cost.

“I believe this breakthrough could minimise the geographical constraints for future research,” Professor He added.

TitleNew inventions boost renewable energy
DescriptionLed by Professor He Jr-hau from the Department of Materials Science and Engineering at City University of Hong Kong (CityU), the material scientist and his research teams are advancing the frontiers of renewable energy research with two significant inventions. They include the development of a novel wave energy device that generates energy while reducing carbon dioxide (CO2), as well as a new photoelectrochemical system that will increase the efficiency of solar-to-hydrogen energy conversion by two-fold and at half the cost.

The findings were published in Energy & Environmental Science under the title “Blue energy fuels: converting ocean wave energy to carbon-based liquid fuels via CO2 reduction” and Nature Communications under the title “An efficient and stable photoelectrochemical system with 9% solar-to-hydrogen conversion efficiency via InGaP/GaAs double junction” respectively.
