Hong Kong has been recognized as having the world’s best public transport system, according to a recent Time Out magazine survey. The survey gathered insights from 18,500 locals across 50 countries, highlighting the critical role of efficient public transport in enhancing urban life. With an overwhelming 98% approval rating from its residents, Hong Kong’s transport network is celebrated for its reliability, affordability, and seamless integration of multiple transit modes.

At the heart of Hong Kong’s success of our transport system is the Mass Transit Railway (MTR), a well-connected network that efficiently links Hong Kong Island, Kowloon, and the New Territories. With 10 lines, frequent service, air-conditioned facilities, and exceptional cleanliness, the MTR has become a global model for urban mobility. This backbone is further supported by air-conditioned buses, minibuses, ferries, and the iconic double-decker trams, ensuring that every part of the city is accessible.

Affordability is another hallmark of Hong Kong’s public transport system. Unlike cities such as London or Sydney, where transit costs can strain household budgets, Hong Kong offers a cost-effective solution that remains inclusive for all residents. The Octopus card, a contactless payment system, further enhances convenience by allowing seamless travel across different modes of transport. This affordability not only makes public transport accessible but also encourages its widespread use, reducing congestion and reliance on private vehicles.

Hong Kong’s public transport success reflects a broader trend of excellence across Asia. Cities such as Shanghai and Beijing, which ranked second and third in the Time Out survey, have invested heavily in infrastructure to meet the demands of urbanization. Shanghai’s state-of-the-art maglev train and Beijing’s expansive subway network exemplify the innovative approaches adopted by cities across the continent. This regional dominance underscores Asia’s commitment to leveraging technology and strategic planning to create world-class public transport systems.

On the other hand, Hong Kong faces challenges as it continues to grow. One of the most pressing is the development of the Northern Metropolis, an ambitious project aimed at transforming the northern New Territories into a vibrant economic and residential hub. This initiative promises to address housing shortages and stimulate economic growth, but it also places significant demands on the city’s transport network. Expanding the MTR and other transit systems to serve this new area will require meticulous planning, substantial investment, and a commitment to maintaining the efficiency and connectivity that residents have come to expect.

Looking to the future, Hong Kong has an opportunity not only to overcome existing challenges but also to become a global leader in sustainable urban mobility. Among the most promising pathways is the integration of hydrogen energy as a central feature of its transport system. Hydrogen-powered buses, trains, and ferries provide a compelling answer to key urban transport issues, including high operational costs, air pollution, and the urgent need for greater energy efficiency. Recognising the substantial benefits of hydrogen energy in driving a sustainable economy and achieving carbon neutrality, the Environment and Ecology Bureau established the Inter-departmental Working Group on Using Hydrogen as Fuel in 2022. This collaborative initiative involves 12 relevant bureaux and departments working together to develop best practices, regulations, and safety standards tailored specifically to Hong Kong's unique context. Furthermore, the group is actively exploring pathways for the advancement and commercialisation of various hydrogen technologies, promoting pilot projects that test hydrogen applications locally to ensure alignment with Hong Kong's long-term development objectives.

Hydrogen energy, often referred to as a “green fuel,” is produced through processes that can be powered by renewable energy sources such as wind and solar. When used in vehicles, hydrogen produces only water as a by-product, making it a zero-emission alternative to fossil fuels. For a dense and bustling city like Hong Kong, where air quality is a recurring concern, the adoption of hydrogen-powered transport could significantly reduce pollution levels. Cleaner air would not only enhance the quality of life for residents but also contribute to the city’s broader environmental goals.

Moreover, hydrogen-powered transport systems have the potential to lower operational costs over time. While the initial investment in hydrogen infrastructure may be substantial, the long-term savings in fuel and maintenance costs can make it a cost-effective alternative to traditional energy sources. Hydrogen fuel cells are highly efficient and durable, requiring less frequent replacement compared to conventional engines. These cost savings can be passed on to commuters, further enhancing the affordability of Hong Kong’s public transport system.

The scalability of hydrogen energy also makes it an ideal choice for a city with diverse and interconnected transit modes. Hydrogen buses, for example, can be deployed to serve urban and suburban areas where electrification may be less feasible. Similarly, hydrogen-powered ferries could operate along Hong Kong’s busy waterways, providing a sustainable alternative to diesel-powered vessels. The integration of hydrogen energy across multiple modes of transport would reinforce Hong Kong’s reputation as a leader in technological innovation and sustainability.

Additionally, the adoption of hydrogen energy aligns with global trends toward decarbonization and renewable energy. As nations worldwide commit to reducing greenhouse gas emissions under international agreements like the Paris Accord, cities that prioritize sustainable transport solutions will be better positioned to attract investment and foster economic growth. For Hong Kong, embracing hydrogen energy would not only reduce its carbon footprint but also solidify its status as a global pioneer in eco-friendly urban mobility.

While the transition to hydrogen energy presents challenges, including the need for infrastructure development and regulatory adjustments, it is a necessary step for Hong Kong to maintain its leadership in public transport. Investments in hydrogen refueling stations, research and development, and public-private partnerships will be crucial to realizing this vision. Fortunately, Hong Kong’s history of innovation and strategic planning provides a strong foundation for tackling these challenges.

Hong Kong’s public transport system is a global benchmark of efficiency, reliability, and affordability. Its success is rooted in thoughtful urban planning, technological innovation, and a commitment to meeting the needs of its residents. However, as the city prepares for future challenges like the Northern Metropolis and the growing demand for sustainability, it must continue to evolve. By embracing hydrogen energy and other green technologies, Hong Kong has the potential to redefine urban mobility for the 21st century. Through sustainable practices, lower costs, and reduced pollution, the city can not only maintain its position as a leader in public transport but also inspire other cities around the world to follow its example. Hong Kong’s journey demonstrates that with vision and determination, a city can move beyond merely transporting people—it can transform lives, communities, and the environment.
