Prof. NI Meng, RISUD member, discusses hydrogen energy development on RTHK TV programme

Prof. NI Meng, Management Committee Member of the Otto Poon Charitable Foundation Research Institute for Smart Energy (RISE), Member of the Research Institute for Sustainable Urban Development (RISUD), Associate Dean (Research) of the Faculty of Construction and Environment and Chair Professor of Energy Science and Technology, shared his expertise on hydrogen energy in a recent interview with RTHK TV programme Hong Kong Connection. Prof. Ni elaborated on the benefits and limitations of grey, blue and green hydrogen, emphasising their important roles in the global transition to sustainable energy systems. He also pointed out that renewable energy supply and demand are not always matched, resulting in the generation of more renewable energy than needed, hence causing renewable energy being wasted; if the excess renewable energy can be used to produce hydrogen, this can not only avoid energy waste, but also truly achieve zero-emission hydrogen production, contributing to carbon neutrality and sustainability.

Prof. Nathanael JIN writes commentary on microbial risks of plastic pollution for Nature prediction service

Prof. Nathanael JIN Ling, Member of the Research Institute for Sustainable Urban Development (RISUD), and Assistant Professor in the Department of Civil and Environmental Engineering and the Department of Health Technology and Informatics, was invited by Nature to contribute a commentary titled “What harmful microbes are lurking in the world’s 7 billion tonnes of plastic waste?”.   In the paper, Prof. JIN and his team highlighted the microbial risks associated with plastic pollution and proposed a global strategy to address these challenges. Plastic debris creates a new ecological niche for microorganisms, forming a new ecosystem known as the “plastisphere”. The paper outlines the potential risks of plastisphere microbiomes pose to ecosystem functioning and the health of humans and other organisms. To develop a comprehensive global strategy, the paper suggests six priorities: quantifying effects, redefining plastic pollution, sustaining funding, establishing expert panels, adjusting management strategies and protecting people.   Read the full paper: https://doi.org/10.1038/d41586-024-03150-6  

Prof. Vivien LU integrates green radiative cooling coating with photovoltaics for energy saving in buildings

The PolyU Carbon Neutrality Funding Scheme aims to support the application of university research outcomes and to take the campus as a testbed to apply research solutions, with a goal of achieving carbon neutrality on campus and supporting Hong Kong’s goal of reaching carbon neutrality by 2050. With support from the Scheme, Prof. Vivien LU Lin, Member of the Otto Poon Charitable Foundation Research Institute for Smart Energy (RISE), Research Institute for Sustainable Urban Development (RISUD) and Research Centre for Resources Engineering towards Carbon Neutrality (RCRE), and Professor of the Department of Building Environment and Energy Engineering, and her research team, has integrated the solar-driven adaptive radiative cooling (SARC) coating they developed, with bifacial solar photovoltaics (PV) to achieve synergistic enhancement in thermal management and power generation, transforming buildings from energy consumers into energy harvesters. The team is planning to install bifacial PV panels on the rooftops of the under-construction PolyU Kowloon Tong Student Hostel, with new coating applied on the corresponding area under the panels, to enhance power generation while radiatively cooling the buildings.   The carbon dots (CDs)-driven photoluminescent radiative cooling nanocoating can be applied to building rooftops and exterior walls. This novel coating can automatically adjust its absorption and emission of solar and thermal radiation in response to changes in environmental temperature or light conditions, helping to mitigate the heat island effect caused by building materials. It uses photoluminescence technology to convert ultraviolet light into visible light, thereby improving the absorption and utilisation of light by PV and increasing its conversion efficiency.   Compared to traditional coatings, this novel coating can effectively improve effective daytime solar reflectance from 92.5% to 95%, increase the cooling effect by 10% to 20%, and reduce the temperature by up to 25°C when applied to concrete rooftops. This nanocoating is environmentally friendly, water-soluble, volatile organic compounds (VOCs)-free, and can be produced in various colours, thus demonstrating significant application potential.   Press Release: https://www.polyu.edu.hk/media/media-releases/2024/0924_polyu-researchers-unveil-novel-carbon-dots-driven-green-radiative-cooling-coating/ Online coverage: Sing Tao Headline - https://polyu.me/4hofXLG (Chinese only)
