Integrated development of rail transit and new energy

Rail transit is recognized as a significant sector in terms of energy consumption and carbon emissions. The transformation of its energy structure and the establishment of a new rail transit energy system characterized by energy self-sufficiency are considered crucial measures for achieving the "dual-carbon" goals. A systematic investigation of the integrated development of rail transit and new energy is conducted in this paper. Against the backdrop of global climate change and energy transition, the demand characteristics for such integration are analyzed, and the corresponding forms and models are categorized. Furthermore, key enabling technologies for the integrated development of rail transit and new energy are explored, with directional guidance for future advancements in this field being provided.
