ME PhD Team Wins Excellence Award at 2025 Net Zero Tech International Contest

A team of four postgraduate students from the Department of Mechanical Engineering at The Hong Kong Polytechnic University (PolyU) has won the Excellence Award at the 2025 Net Zero Tech International Contest. The team was recognized for their outstanding performance in the finals, held at National Taiwan University. Selected as one of only 20 finalist teams from a pool of 230 registrations across 11 countries, the PolyU team presented their project, "Development of a smart mini-grid system for renewable energy storage and utilization." The project's core innovation is its use of vanadium redox flow battery (VRFB) technology, which offers a high energy capacity, long cycle life, and the unique ability to decouple power and energy ratings. Under the supervision of Prof. AN Liang, the team—comprising leader Miss Huo Xiaoyu and members Miss Bai Yuran, Mr Long Xin, and Mr Fu Enkang—developed a functional smart mini-grid that integrates their VRFB with a 5 kW solar panel. The system's feasibility was rigorously validated through a staged development process, beginning with a 50 W prototype and scaling up to a fully functional 5 kW/20 kWh stack. The project aims to improve energy efficiency, create economic value, and reduce environmental impact. Beyond its technical merits, it supports the broader adoption of renewable energy and contributes to the global transition toward a low-carbon economy. Jointly organized by National Taiwan University and the TECO Technology Foundation, the Net Zero Tech International Competition is dedicated to cultivating talent in net-zero emission technologies. The contest provides a global stage for young scholars to propose innovative and practical solutions in green energy and sustainable innovation.

Prof. Cheng Song Leads Groundbreaking Collaboration with Boeing and COMAC

Prof. CHENG Song from the Department of Mechanical Engineering at PolyU has received an industrial support from Boeing and COMAC to launch a groundbreaking 4.5 million HKD project, aiming at developing sustainable aviation fuels (SAF) with blending ratios greater than 50% with conventional jet fuels. SAFs are produced from renewable resources and have the potential to reduce lifecycle greenhouse gas emissions by up to 80% compared to conventional jet fuel. SAF is widely recognized as one of the most promising solutions for decarbonizing the aviation sector, enabling airlines to significantly lower their carbon footprint while maintaining high safety and performance standards. The development and adoption of high-blend SAFs are critical steps toward achieving the aviation industry’s net-zero emissions goals. This project seeks to address this urgent need. By focusing on high-blend and even unblended SAF, the project will push the boundaries of current fuel standards and pave the way for a new era of cleaner, more sustainable air travel. In addition to laboratory research, engine testing, the project will also explore the supply chain, infrastructure, and policy frameworks necessary to support widespread adoption of high-blend SAFs.
