摘要
Abstract
In order to study the economy of long-distance transportation of hydrogen,two different transportation methods were selected for economic evaluation.One method is to convert renewable energy into electrical energy,transmit it through high-voltage DC cables,and ultimately electrolyze water to produce hydrogen at the user end.Another way is to first convert renewable energy into hydrogen,and then transport the hydrogen to users through natural gas pipelines.By using the method of group comparison,the analysis objects were divided into four groups:offshore cables,onshore cables,offshore pipelines,and onshore pipelines.Summarize data to analyze the impact of factors such as transmission distance,capacity factor,and transmission capacity on the levelized cost of energy of hydrogen among the four transmission methods.The results show that the lowest LCOE for transporting hydrogen through pipelines is ＄7/kg at a transmission distance of 4 000 km.The lowest LCOE for converting electrical energy through cables into hydrogen energy transmission is ＄9/kg.By increasing the transportation capacity coefficient and scale,the transportation cost of hydrogen can be further reduced.关键词
