Hong Kong has received its first hydrogen-powered light rail train as part of its efforts to develop the use of hydrogen energy to achieve carbon neutrality by 2050. The train, currently undergoing tests, will have a trial run in Tuen Mun later this year. This initiative is part of a larger plan by the city's rail operator, the MTR Corporation, and is one of 14 hydrogen projects approved by environmental authorities. The MTR Corp aims to use this trial run to assess the feasibility of hydrogen as a clean energy option for its network. Other approved hydrogen projects in Hong Kong include a refilling station plan by Sinopec, a shipping scheme by Linde HKO, and a road test of a hydrogen-powered double-decker bus by Citybus. The city's government released a Climate Action Plan in 2021, setting a target of net-zero carbon emissions by 2050, and has recently unveiled a strategy for hydrogen development to legalize its use as an energy source while addressing concerns about safety and regulations around hydrogen production and transportation.
