摘要
重型货车是我国交通运输行业的高耗能设备和主要的碳排放来源,其柴油年消耗量约占我国柴油年消耗总量的40%、CO_(2)年排放量占交通运输领域CO_(2)年排放总量的50%左右。在“双碳”目标和能源革命的背景下,构建绿色清洁、安全高效的公路货运方式,推进重载货运交通的低碳化和清洁化转型,这已成为一种必然趋势。目前,重型货车电气化主要有充电方案、换电方案、氢能重卡方案以及电气化公路方案。文章主要介绍了氢能重卡方案和电气化公路方案,并基于某运煤专线,通过成本核算,对比分析了二者的经济性和应用场景。分析结果表明,对于固定运输线路的货运交通,当年运量大于204.83万吨时,采用电气化公路方案更具有经济性;当年运量低于204.83万吨时,氢能重卡方案成本则更低。
Freight transport with heavy trucks has emerged as a significant energy-intensive sector and a major contributor to carbon emissions in China's transportation industry.The diesel consumption in this field represents approximately 40%of China's total annual diesel consumption,while the CO_(2) emissions account for approximately 50%of the total annual CO_(2) emissions in the transportation industry.Under the background of carbon peaking and carbon neutrality goals and energy revolution,it has become an inevitable trend to build a green,secure and efficient road freight mode and promote the low-carbon and clean transformation of heavy freight transport.So far,the electrification options of freight transport with heavy trucks mainly include charging,battery swapping,hydrogen heavy trucks,and electrified highways.This paper mainly introduces the hydrogen heavy truck and electrified highway options.Based on a dedicated coal transport route,the economic efficiency and application scenarios were compared and analyzed between these two options from a perspective of cost estimates.The analysis results show that,for this dedicated coal transport route,when the annual traffic volume is greater than 2.0483 million tons,the electrified highway option is more economical,while on the contrary,the cost of the hydrogen heavy truck option is lower.
