PolyU and CLP Power co-develop smart “Generator Inspection Robot”, spearheading innovative solutions through academia-industry synergy to drive research translation and talent development

PolyU and CLP Power Hong Kong Limited (CLP Power) have jointly developed a smart “Generator Inspection Robot”. By integrating robotics with fibre-optic sensing technology for generator inspections, the project overcomes traditional manual inspection limitations, significantly enhancing the efficiency of inspections and operational safety. The project won a Gold Medal and a special prize—Best International Invention & Innovation, from the National Research Council of Thailand—at the 51st International Exhibition of Inventions Geneva. This international recognition testifies to the achievements of PolyU and CLP Power in fostering industry-academia-research collaboration, injecting momentum into Hong Kong’s development in innovative technology and research talent. A highly reliable electricity supply is vital to the city’s social and economic development. As a core facility of the power system, generator inspection and maintenance always require a high level of technical expertise and stringent safety standards. A generator primarily comprises the stationary outer component “stator” and the internal rotating component “rotor”. Traditional inspections require the removal of the rotor that weighs approximately 50 tonnes, a complex process involving heavy lifting operations and extensive logistical arrangements. In light of the unique design of some gas-fired generators at CLP Power’s Black Point Power Station, which incorporate internal ventilation baffles, no suitable robotic inspection solutions had previously been available on the market. In response to this operational need, Prof. TAM Hwa-yaw, Associate Director of the Photonics Research Institute (PRI) and Chair Professor of Photonics of the Department of Electrical and Electronic Engineering, led a team of researchers and undergraduates to collaborate with CLP Power’s Generation Business Group to develop a 36‑millimetre‑thick “Generator Inspection Robot” specifically designed to suit the structural characteristics of the generators concerned. The robot can flexibly navigate the narrow air gaps between the rotor and the stator, and cross the ventilation baffles inside to automatically complete major inspection tasks without removing the rotor. These inspections include visual checks of ventilation ducts, assessing the insulation condition of stator core laminations and conducting wedge tightness inspections through tapping. Compared to manual inspection, the robot helps enhance inspection efficiency while optimising long-term maintenance arrangements. The robot is also equipped with a fibre-optic sensing network to monitor the operational status of its own key components. This ensures its operational stability while navigating the generator’s air gaps, ensuring smooth progression of inspection tasks.

From emissions to fuels: Advanced electrocatalytic CO₂ reduction demonstrates economic viability for large-scale carbon-neutral fuel and chemical production

Electrocatalytic carbon dioxide reduction (ECO₂R) offers a sustainable pathway to industrial decarbonisation by converting carbon dioxide (CO₂) into carbon-neutral fuels and chemicals. Despite significant advances in catalyst design, industrial scalability has been constrained by slow mass-transfer kinetics. A research team led by Prof. Daniel LAU Shu-ping, Associate Director of Photonics Research Institute (PRI) and Chair Professor of Nanomaterials, has introduced a high-diffusion-flux gas diffusion electrode (HDF-GDE) that overcomes this limitation in alkali-cation-free systems, achieving CO₂ conversion rates at industrial current densities. Kinetic analysis reveals that conversion is governed by mass transfer efficiency rather than flow rate. By optimising the GDE structure to maximise CO₂ diffusion and GDE utilisation, the team has realised a kW-scale ECO₂R system with long-term stability (1000 hours), capable of producing carbon monoxide (CO) or ethylene (C₂H₄) depending on the catalyst employed. Operating with a 3 L/min CO₂ flow rate, the system delivers 144 kg of CO (1.29 kW) or 17 kg of C₂H₄ (1.95 kW) over 1000 hours. The alkali-cation-free ECO2R system, equipped with HDF-GDEs, demonstrates economic viability for large-scale ECO2R-to-CO/C2H4 production. These findings bridge the gap between laboratory innovation and real-world deployment, advancing the manufacturing of carbon-neutral fuels and chemicals. This breakthrough not only addresses key challenges in mass transfer and system stability but also paves the way for the practical implementation of ECO₂R technology in industrial settings. By demonstrating both technical and economic feasibility, the research sets a new benchmark for scalable carbon-neutral fuel and chemical production, supporting global efforts toward sustainable energy and climate change mitigation. The results have been published in Nature Communications under the title “Kilowatt-scale alkali-cation-free CO2 electrolysis via accelerating mass transfer”.

Prof. TAM Hwa Yaw featured in 21st Century Business Herald: Reflecting on thirty years of fibre optics research and start-up incubation

Prof. TAM Hwa Yaw, Associate Director of Photonics Research Institute (PRI) and Chair Professor of Photonics, was recently featured in 21st Century Business Herald.  He shared insights from more than thirty years of dedicated research and application in fibre optic technology, as well as his experience in successfully incubating seven companies. Prof. Tam candidly remarked, “It wasn’t that I chose fibre optics, but rather that fibre optics chose me.” This statement reveals the profound bond he has with the technology.  Born in Brunei and raised in Malaysia, Prof. Tam once faced the challenge of being stateless and without a passport due to his unique circumstances.  To broaden his career prospects, he switched from physics to electronic engineering, and it was at the University of Manchester in the UK that he first encountered fibre optic communications—thus beginning his academic and industrial journey. In 2014, Prof. Tam led his team to establish the world’s first city-scale fibre optic sensing network, covering 90% of Hong Kong’s railways, and later expanding the technology to Singapore, the Netherlands, Australia, and other regions.  His railway laser sensing technology earned him the Berthold Leibinger Innovationspreis, one of the highest-prized international innovation awards in laser technology.  In recent years, Prof. Tam has further applied fibre optic sensing technology to the medical field, collaborating with the university and hospital in Australia to develop plastic fibre optic sensors for cochlear implant surgery, significantly enhancing the safety and precision of the procedure.  This technology is now entering clinical trials. Prof. Tam places great emphasis on the integration of academia, industry and research, encouraging students to engage in hands-on practice.  He founded the Engineering Entrepreneurship Club to promote interdisciplinary collaboration and innovation among undergraduate students. Speaking on the transformation of research into industry in Hong Kong, he believes that government policy support is crucial, and suggests that young scholars should focus on research, while senior academics should actively drive the industrialisation of research outcomes.  Prof. Tam’s journey exemplifies innovative breakthroughs and outstanding contributions, spanning from academia to industry, and from large-scale railway systems to microscopic medical applications.
