我国首个！取得重要进展

Core Viewpoint - The successful completion of China's first long-distance pipeline modification for carbon dioxide transportation marks a significant advancement in the resource utilization of existing long-distance pipelines, providing a replicable engineering demonstration for the large-scale promotion of carbon capture, utilization, and storage (CCUS) industry [1][3][5] Group 1 - The trial was conducted on a decommissioned pipeline, where workers performed adaptive evaluations and comprehensive safety renovations to transport carbon dioxide through a 21-kilometer decommissioned pipeline and a 6-kilometer newly constructed high-pressure flexible composite pipe to the Zhongyuan Oilfield for oil recovery and storage operations [3] - Despite significant carbon reduction achievements, China's annual carbon dioxide emissions still exceed hundreds of billion tons, necessitating the construction of a long-distance, safe, and economical carbon dioxide transportation system, with the modification of existing long-distance pipelines being a crucial solution [3][5] Group 2 - The successful trial opens new pathways for the green transformation of China's energy industry and strongly supports the transition of CCUS from demonstration applications to large-scale development, facilitating the early realization of the "dual carbon" goals [5]
