Hong Kong will seek to become mainland China’s showcase for developing hydrogen under new plans that will legalise the widespread use of the energy source for vehicles by next year in a push to cut carbon emissions, the city’s environment chief has said.

Environmental authorities on Monday presented a street washer that runs on the gas as part of a road map to spur hydrogen innovation and introduce new legislation in the sector by 2025.
Unlike conventional petrol vehicles that emit greenhouse gases such as carbon dioxide and methane, those that use hydrogen produce only water vapour during combustion.

“Our country already has a strong foundation in hydrogen development, which is a key component of our national energy sources,” Secretary for Environment and Ecology Tse Chin-wan told a press briefing.

“If Hong Kong can seize this opportunity, the city will progress towards its goal of carbon neutrality, develop new quality products and maintain Hong Kong’s international competitiveness.”

Tse said the city should also leverage its unique advantages of “enjoying the strong support of the motherland” while being “closely connected to the world” so Hong Kong could be a touchstone that demonstrated the country’s development of hydrogen energy.
