[Introduction] China's transportation sector is a significant contributor to carbon emissions. To achieve carbon peaking and neutrality, developing a new transportation-energy integrated system based on energy Internet is a crucial step for the low-carbon transition of this sector. [Method] Focusing on low-carbon transition, this paper provided an overview of the development goals, policy background, innovations, and insights of China's new highway transportation-energy integrated system. [Result] Centered on the multi-objective demand of "energy-saving transportation – economical transportation – low-carbon transportation", various transportation-energy integrated service business models has been developed for China's new highway transportation-energy integrated system, such as battery charging & switching systems, PV-storage-charging integration systems, and oil-gas-hydrogen-electricity-PV charging & storage systems. Corresponding collaborative planning and construction, operation and control, advanced energy storage, multilevel coordination of energy management, and other key technologies are also being gradually developed. However, challenges related to planning, operation and environmental protection remain. To facilitate the rapid advancement of this integrated system, efforts should focus on expanding market awareness, streamlining regulations and strengthening technical collaboration in the next stage. [Conclusion] This paper discussed China's new future-oriented highway transportation-energy integrated system, offering valuable perspectives on enhancing the quality development of China's transportation sector. |
