Hong Kong's Transport Future: Balancing Electric and Hydrogen Power


Hong Kong is considering the future of its public transport, debating the merits of hydrogen-powered versus electric buses. While currently most hydrogen fuel is grey hydrogen, it still has a lower carbon intensity than coal-generated electricity, which powers many electric vehicles (EVs). Green hydrogen, despite its current limitations, is seen as the ultimate goal, and early adoption could help reduce costs over time. Hydrogen buses offer operational advantages such as faster refueling and longer range, while electric buses benefit from higher end-user energy efficiency. Both technologies have their place in Hong Kong's transport system, and their combined use could help the city achieve zero-carbon transportation. Additionally, the rise in EV popularity, indicated by the installation of more quick chargers, and the lessons from Dubai's floods highlight the importance of sustainable practices and resilient infrastructure in the face of climate change.
