Smart building skins and eco-friendly hydrogen production technology

The JC STEM Lab of Circular Bio-economy (the Lab) at City University of Hong Kong (CityUHK) has recently achieved a breakthrough in the field of sustainable development technologies. A research team led by Professor Lee Duu-Jong, Director of the Lab and Professor in the Department of Mechanical Engineering, has successfully developed a bio-inspired “all-weather building skin” that cools in sunlight and harvests energy from rain, alongside a “turbocharged” solar hydrogen system powered by low-cost copper ions.
