Abstract:Based on the status quo analysis of energy consumption in the transportation sector in the Guangdong-Hong Kong-Macao Greater Bay Area(GBA), this paper develops a long-range energy alternatives planning system model (LEAP-GBA Transportation Model) to simulate future energy consumption trends of transportation in GBA from 2017 to 2035 under three scenarios: baseline scenario (BS), energy transformation scenario (ETS), and deep energy transformation scenario (DTS). Then the paper discusses the energy saving potentials and the energy transformation directions and paths of transportation sector from the sub-sectors like freight transportation, intercity passenger transportation, and intra-city passenger transportation. Results show that the energy demand of transportation in GBA will continue to grow, which means great pressure on energy saving in the transportation sector. Under ETS and DTS scenarios, with the more stringent policies, the energy consumption demand is expected to peak between the year of 2025 and 2030. It is suggested that to realize the energy transition in the transportation sector of GBA, it is necessary to vigorously promote the application of clean energy such as natural gas, electricity, hydrogen and biofuels, promote the development of railway and waterway transportation, as well as urban public transportation, and improve the energy efficiency by strengthening technical energy conservation and improving management level.
