Hong Kong is aspiring to establish itself as a leading hydrogen-fuel supply hub for the maritime and aviation sectors, a vision that hinges on strategic investments and policy frameworks according to experts. The city's first hydrogen refueling station and deployment of a hydrogen fuel-cell double-decker bus by CIMC Enric Holdings mark significant progress in this direction. There is a call for more demonstration projects to showcase the viability of hydrogen in various applications and the importance of government support and partnership to drive the adoption of clean fuels. Recent initiatives by the Hong Kong government include a hydrogen promotion strategy, actions to facilitate green methanol use, and a feasibility study on green methanol and green ammonia for vessels. Challenges such as ensuring a green hydrogen supply chain, managing costs, logistics, and regulatory aspects need to be addressed collaboratively by stakeholders. The potential of Hong Kong to become a sustainable aviation fuel (SAF) supply hub is also highlighted, contingent on securing adequate feedstock. Comparisons with Singapore's advanced SAF policymaking underscore the progress needed in Hong Kong. CIMC Enric's plans to build a green methanol plant using waste from the pulp and paper industry reflect the commitment towards sustainable practices. The company's willingness to collaborate on hydrogen projects in Hong Kong signals a positive step towards achieving the city's green fuel ambitions.
