Is the hydrogen-powered train a possibility for Hong Kong’s new railway projects?

Prized for its emission-free nature, cutting-edge hydrogen fuel cell technology is maturing and thus gaining global interest. As a sustainable energy source and storage, hydrogen power has grown into a possible solution to curtail global warming. In the transport industry, the hydrogen train has been seen as a successful application in Germany. With the new railway project opportunities in Hong Kong, this study will examine the preliminary feasibility of introducing hydrogen trains to this cosmopolitan city in Asia. This paper focuses on the socio-economic impact on various stakeholders as a qualitative analysis. The carbon footprint savings in switching to hydrogen train operation is estimated as quantitative analysis.
