In Hong Kong, the Inter-departmental Working Group on Using Hydrogen as Fuel has recently approved four additional trial projects focused on hydrogen fuel technology. These projects include initiatives such as producing hydrogen using solar energy at a landfill, testing hydrogen fuel cell buses, forklifts, and vehicles, and establishing hydrogen refueling stations. The government is actively promoting hydrogen development through various measures, including funding schemes, safety regulations, standard certifications, and public outreach efforts. Collaboration with Mainland authorities is also planned to discuss cross-boundary hydrogen energy development issues in 2025. The Working Group, comprising representatives from various government departments, is working towards refining safety and technical guidelines for local hydrogen energy applications by referencing operational data and experiences from these trials.
