摘要

二氧化碳的运输在碳捕集利用与封存技术的应用中起着至关重要的作用,对该技术的经济性和减排效果有着重要影响。然而,在专门针对中国的不同陆上运输方式的综合评估和比较方面,文献中存在明显的差距。特别是对油罐车运输的评价研究不足。本研究采用生命周期评估方法,对中国管道和油罐车两种二氧化碳运输方式的成本和碳足迹进行了评价和比较。评估表明,在20年的运营时间内,中国管道运输和油罐车运输的成本分别为0.2584元和0.2306元/吨·公里。管道运输的CO2全生命周期碳排放量为0.0939 kg/t·km,比油罐车运输减少9.62 %。管道的生产主要决定了管道运输的成本和碳足迹,而油罐车运输主要受操作和维护过程的影响。运营年限、价格因素和折现率影响两种运输方式的单位运输成本,运输距离影响碳足迹的比较;这些因素的变化共同决定了最佳运输方式的决定。本研究提出通过车辆-管道运输相结合的方式提高CO2运输的整体效益,通过加强管道防腐等方式减少运输碳排放。

Comparative life cycle assessment of CO2 onshore transport in China: Pipeline or tanker truck?
The transport of CO2 plays a crucial role in the application of carbon capture, utilisation, and storage technology, significantly affecting the economy and emission reduction effectiveness of this technology. Nevertheless, a noticeable gap exists in the literature regarding the comprehensive assessment and comparison of different onshore transport modes specifically focused on China. In particular, there is a lack of evaluation research on tanker truck transport. This study employs a life cycle assessment approach to evaluate and compare the cost and carbon footprint of pipeline and tanker truck transport methods of CO2 in China. The assessments show that, with a 20-year operating time, the costs for pipeline and tanker truck transport in China stand at 0.2584 and 0.2306 CNY/t·km, respectively. The life cycle carbon emissions for pipeline transport of CO2 is 0.0939 kg/t·km, 9.62 % less than tanker truck transport. The production of pipelines primarily dictates the cost and carbon footprint of pipeline transport, whereas tanker truck transport is mainly affected by the operation and maintenance processes. Operating years, price factors and discount rates affect the unit transport cost of both modes, while transport distance influences the comparison of the carbon footprint; changes in these factors together shape the decision of the optimal mode of transport. This study proposes enhancing the overall benefit of CO2 transport through a combination of vehicle-pipeline transport and reducing transport carbon emissions by enhancing pipeline anti-corrosion and other methods.
