Hong Kong, a bustling metropolis known for its high levels of air pollution, is taking a significant step towards carbon neutrality by embracing hydrogen power. Unlike traditional energy sources, hydrogen contains no carbon in its molecular structure and only produces water vapor when burned, reducing air pollution. Secretary for Environment and Ecology, Tse Chin-wan, believes that the development of hydrogen power, coupled with the necessary infrastructure and talent training, will help Hong Kong achieve its goal of carbon neutrality by 2050.
To support this vision, the government has published a new strategy to promote the use of hydrogen energy. Tse emphasizes that hydrogen will be an important component of the national energy system in the future, as stated by the country. By seizing the opportunities presented by hydrogen energy, Hong Kong can not only strive towards carbon neutrality but also develop a new quality productive force and maintain international competitiveness.
There are three different types of hydrogen used today: grey, blue, and green. Grey and blue hydrogen are produced from fossil fuels, with blue hydrogen having a smaller carbon footprint due to carbon capture technology. On the other hand, green hydrogen is derived from renewable energy sources like wind power and solar photovoltaics, making it more environmentally friendly but also more expensive to produce.
The government acknowledges the uncertainty surrounding the price competitiveness of green hydrogen and, therefore, retains flexibility in its strategy. It aims to prevent economic compromise while still pushing forward with innovative and sustainable energy solutions.
Aside from the environmental benefits, Hong Kong hopes to become a showcase for hydrogen development in the nation. Plans include establishing a city certification scheme for hydrogen energy, setting up the city’s first public hydrogen refueling station, and conducting trials on hydrogen-powered street washers. The government also aims to collaborate with mainland China on a hydrogen supply network for the Greater Bay Area.
In the transportation sector, Citybus has already introduced the city’s first hydrogen-powered double-decker bus, with plans to add more in the near future. The MTR Corporation is also set to test a hydrogen-powered light rail train. Additionally, the government plans to incorporate codes of practice for hydrogen-fueled vehicles, maintenance workshops, and refueling stations into the legal framework.
While Hong Kong is making significant progress, similar hydrogen initiatives have been implemented in other parts of the world, including the United States, Europe, and Singapore. The global recognition of hydrogen as a clean energy source emphasizes its potential to transform the energy landscape and contribute to carbon neutrality targets.
With its ambitious strategy and commitment to hydrogen power, Hong Kong is paving the way for a greener future. By embracing innovation and sustainable solutions, the city is not only addressing its air pollution problem but also positioning itself as a leader in clean energy technology. As the journey towards carbon neutrality continues, hydrogen power will play a crucial role in Hong Kong’s sustainable development.
