碳达峰、碳中和背景下新疆CCUS面临的机遇与挑战及未来发展路径OA

Driven by the targets of carbon peaking and carbon neutrality,Xinjiang(China),as the core area of China's energy strategy and the highland of carbon sequestration potential,faces significant opportunities and challenges in the development of its CCUS(carbon capture,utilization and storage)technology.This study systematically analyzes the technological foundation,resource endowment and policy environment of CCUS in Xinjiang(China),and points out three major opportunities.Firstly,the excellent geological conditions made the theoretical storage potential being of over 480 billion tonnes in Junggar and Tarim basins,and high matching degree of sources and sinks.Secondly,clear policy support from the special plans of the state and the autonomous region provide financial and clustering layout protection.Thirdly,the accumulation of technology has been shaped,with the demonstration project of CO2-driven petroleum achieving remarkable results,and pipeline transport and monitoring technology achieving breakthroughs.However,the challenges should not be ignored.The complex geological structure leads to strong reservoir inhomogeneity and high injection pressure,the high cost of the whole process highlights the economic disadvantage,the ecological and environmental risk prevention and control system is missing,capping leakage and groundwater contamination coexist,the mechanism of inter-regional cooperation has not yet been established,and mismatch of source and sink space and contradiction of benefit distribution need to be solved urgently.In the future,it is necessary to reduce energy consumption through technological innovation,optimize policy incentives,improve the risk monitoring network,and promote the'source-sink-market'cross-regional linkage,to realize the large-scale application and sustainable development of CCUS technology in Xinjiang.
