Hong Kong is set to become a hub for hydrogen innovation as part of its strategy to achieve carbon neutrality. The city's environment chief, Tse Chin-wan, highlighted the importance of transitioning to hydrogen-powered vehicles to reduce greenhouse gas emissions. By legalizing hydrogen use for vehicles by 2022 and planning to introduce new legislation by 2025, Hong Kong aims to align with mainland China's advancements in hydrogen technology. The strategy focuses on improving regulations, setting standards, facilitating the market, and advancing talent training for hydrogen applications. Green hydrogen, produced from renewable sources, is prioritized despite its higher cost to ensure environmental benefits while maintaining economic sustainability. With ongoing trial projects and collaborations with companies like Citybus and Towngas, Hong Kong is making strides in implementing hydrogen technology. President Xi Jinping's support for hydrogen energy development in China further underscores the significance of Hong Kong's initiatives. The strategy has received positive feedback from green groups and think tanks, emphasizing the importance of cooperation with the mainland and ensuring public safety in hydrogen usage. With a well-defined road map and regulatory framework, Hong Kong's hydrogen economy is poised for rapid growth, contributing to a cleaner and sustainable future.
