Techeconomic Analysis of Ammonia as Hydrogen Carrier for Transportation and Production

Abstract:

Ammonia is a sort of hydrogenrich material with hydrogen content of 17.6%.Considering the bottleneck problems of hydrogen storage and transportation to date,this paper designs a hydrogen supply pathway with ammonia carrier as the agent of hydrogen storage and transport.Using supply cost of 1 kg hydrogen as economic indicator,through economic analysis and comparison with nature gas reforming,water electrolysis and methanol decomposition pathways,we come the conclusion that on medium hydrogen production scale and in short distance transportation circumstance,the supply cost of ammonia as hydrogen carrier pathway is 51.2 yuan·kg-1,obviously lower than the other threes,showing good performance on economic aspect.
