Expanding on the deep decarbonization roadmap developed in the first report under the Hong Kong 2050 is Now initiative, “Towards a Better Hong Kong: Pathways to Net Zero Carbon Emissions by 2050”, this report focuses on the decarbonization of the power sector in Hong Kong, covering the generation and transmission of electricity and piped gas from a supply perspective. Based on the in-depth analysis of different power technologies, this report defines concrete pathways and implementation roadmaps for policy makers and the power sector.
The analysis presented in this report takes a closer look at developing domestic renewable energy resources, sourcing nuclear and renewable energy from neighbouring regions, replacing coal with gas, coupled with negative emission technologies such as Carbon Capture, Utilization, and Storage (CCUS) technology, or with green hydrogen, and replacing distributed gas with a net-zero emission source.
As zero and low carbon emitting technologies are newer and still being developed, the high costs are often prioritised and prevent the environmental benefit. However, if Hong Kong is to meet its decarbonization targets, greater investment will need to be injected into green products and technologies in order to further develop them and ultimately lower the cost of such technologies to enable widespread use. Hong Kong should continue to explore the use of various technologies and a diverse fuel mix consisting of natural gas, nuclear, renewable energy technologies, hydrogen, and other clean or low carbon sources.
