During a Legislative Council session, Hong Kong's Chief Executive John Lee Ka-chiu announced the upcoming release of the city's hydrogen development plan by the Environment and Ecology Bureau. The plan includes the introduction of hydrogen-powered street washing vehicles and garbage trucks to improve the city's cleanliness. In addition to these vehicles, the government plans to establish hydrogen gas stations and revise laws to ensure safe storage and maintenance of hydrogen due to its combustible nature. The focus on developing new quality productive forces and integrating culture and tourism was emphasized during the session. Furthermore, discussions revolved around challenges in developing a 'low-altitude economy' in a city dominated by high-rise buildings. Lawmaker Elizabeth Quat Pui-fan suggested innovative solutions like helicopter transit services and drone-powered food delivery to enhance local transportation and tourist experiences.
