氢能供应链中最佳运氢方式的选择

Selection of best hydrogen transport mode in the hydrogen supply chain

氢的运输在整个氢能供应链的经济、能耗和排放性能中占有很大比重。该文通过设计以运氢规模和运输距离为特征参数的"点对点"运输情景,对比分析了3种运氢方式(气氢拖车、气氢管道和液氢罐车)在不同情景参数下的成本、能耗和CO2排放特性。分析结果表明不同运氢方式适合不同的运输情景:在以经济性为主要评价指标的前提下,气氢拖车方式适合小规模、短距离运输;气氢管道方式适合大规模、中短距离运输;液氢罐车方式适合长距离运输。

The hydrogen transport is a key part of the economic, energy, and environmental aspects of the hydrogen supply chain. This paper analyzes ＂point-to-point＂ transport scenarios with the hydrogen transport scale and transport distance as the two characteristic parameters, to ealeulate the cost, energy eonsumption, and CO2 emissions of three hydrogen transport modes （tube trailer, gaseous pipeline, and liquid truck）. The results show that the best hydrogen transport mode depends on the transport scenarios. If the economic performance is the primary evaluation criterion, the tube trailer mode is best for small scale, short distance transport, the gaseous pipeline mode is best for large scale and medium to long distance transport ; and the liquid truck mode is best for long distance transport.
