摘要
中国东南部和沿海多个地区只能采用海底CO2地质封存实现大规模的CO2地质封存减排,因此有必要对海底CO2管道运输成本进行分析,获取中国背景下的成本分布范围。基于现有CO2海底管道的技术特征和成本分析方法,建立了海底CO2管道的技术经济模型,并利用该模型和中国价格参数对某CO2海洋封存示范项目的运输部分进行了初步技术设计和成本分析,结果显示：对于给定的100 km管道,当设定输量范围为3~20 Mt/a时,总建设投资范围为7.8×108~13.9×108元人民币,平准化成本为0.10~0.41元人民币。通过分析中国某海上CCS示范工程海底CO2管道运输的技术特征和成本范围,为中国CO2海底管道的建设提供了参考。
Many regions in coastal and southeastern China can only achieve CO2-emission reduction by offshore carbon capture and storage （CCS）. Accordingly, it is necessary to assess costs related to transmission of CO2 through subsea pipelines to clarify range of cost distribution in China. With consideration to characteristics of existing technologies and relevant costs for transmission of CO2 through subsea pipelines, technical and economic models are established to accomplish preliminary design and cost analysis for transmission section of an offshore CO2 storage project by using domestic cost factors. The results show that the capital cost of a 100 km pipeline ranges from RMB0.78 billion to RMB 1.39 billion when the design throughout is 3-20 Mt/a, whereas the levelized cost ranges in RMB0.10-0.41. This study gives techno-economic features of the subsea CO2 pipeline transportation for a give case in China, and may provide valuable references for construction of subsea pipeline for CO2 transmission.
