Assistant Professor Zuming Liu and his team from the College of Smart Energy at Shanghai Jiao Tong University published a paper titled "Low-carbon transition pathways of power systems for Guangdong-Hongkong-Macau region in China" in Energy & Environmental Science—a renowned journal in the energy field. The paper proposes a comprehensive assessment model for energy systems with high spatiotemporal resolution, integrating investment planning and operational scheduling. It studies multi-scenario low-carbon transition pathways for the power system in the Guangdong-Hong Kong-Macau region, and finds that to achieve net-zero emissions in the region’s power system by 2050, an average annual expenditure of 21.8 billion US dollars is required, accounting for 0.94% of the regional gross domestic product (GDP) of the Guangdong-Hong Kong-Macau region in 2021. If net-zero emissions are to be achieved before 2035, the average annual expenditure will need to increase by 5.18%.

The study also reveals that increasing fossil fuel prices and strengthening the transmission network are conducive to promoting the low-carbon transition of the energy system in the Guangdong-Hong Kong-Macau region.
