The Environment & Ecology Bureau in Hong Kong has announced the approval of four new trial projects focusing on hydrogen fuel technology. These projects, which received agreement-in-principle from the Inter-departmental Working Group on Using Hydrogen as Fuel, showcase the city's commitment to exploring and implementing hydrogen energy solutions. The first project involves Sinopec (Hong Kong) and aims to produce hydrogen using solar energy at the restored Pillar Point Valley Landfill in Tuen Mun. The second project, jointly submitted by companies including China State Construction Engineering (Hong Kong), will trial hydrogen fuel cell vehicles for shuttle service at a construction site. The third project, a collaboration between Kingroad Logistics, Allenbus Automotive Technology Co., and Hong Kong Hydrogen Fuel Cell Company, will test an HFC medium goods vehicle for cross-boundary transport. The fourth project, by Sinopec (Hong Kong), will involve testing an HFC light goods vehicle at its oil terminal in Tsing Yi. Hong Kong has already witnessed the introduction of hydrogen technology in public services, such as the Citybus's HFC double-decker bus now operating daily passenger services. Additionally, Sinopec (Hong Kong) recently completed the construction of Hong Kong's first public hydrogen refueling station at Au Tau, Yuen Long, which is set to supply hydrogen to upcoming HFC street-cleaning vehicles. To ensure the safe use of hydrogen fuel, efforts are being made to amend regulations. The Electrical & Mechanical Services Department is collaborating with the Department of Justice to amend the Gas Safety Ordinance, with plans to introduce a bill to the Legislative Council next year. Moreover, initiatives are underway to provide safety training courses for professionals in the hydrogen fuel trade, in coordination with the Vocational Training Council and hydrogen fuel system suppliers. The approval of these trial projects and the advancements in regulations reflect Hong Kong's positive stance towards embracing hydrogen fuel technology. With 18 hydrogen energy trial projects approved so far, the city demonstrates its commitment to innovation and sustainability in the energy sector.
