Technical and economic analysis and outlook of hydrogen energy industry
Under carbon peaking and carbon neutrality goals,hydrogen energy assists the power production system,it's great significance for carbon peak and carbon neutralization.This paper introduces the development status,significance and application prospect of the hydrogen energy industry;summarizes the current economic and technological development of hydrogen industry in hydrogen production,storage and transportation,and hydrogen energy application,and focuses on the analysis of the technical and economic problems in the storage and transportation process of the hydrogen industry chain,and compares the levelized cost of the different ways of storage and transportation,including the gas-hydrogen long-tube trailer,tanker transportation,pipeline transportation,and marine transportation,and the results of this analysis show that the gas-hydrogen transportation by pipeline has the lowest storage and transportation cost,and is suitable for long-distance,large-scale and large-scale transportation.The analysis results show that pipeline hydrogen transportation has the lowest storage and transportation costs and is suitable for long-distance,large-scale and stable hydrogen demand scenarios;small-scale liquid hydrogen has the highest storage and transportation costs and is mainly used in aerospace and less for civilian use;high-pressure cylinder hydrogen storage and high-pressure gas-hydrogen long-tube trailer technology is mature and is the mainstream storage and transportation mode at home and abroad,which is not suitable for large-scale and long-distance transportation.Hydrogen industry still has various challenges such as high cost,safety risk and conversion efficiency in hydrogen production,storage and transportation,and hydrogen application.The future development of hydrogen energy needs to be improved in terms of no breakthroughs in key technologies,reduction of operating costs,development of related technical standards,and government subsidies.It is of great significance to predict the cost of hydrogen production,storage,transmission,distribution and application in the era of large-scale hydrogen energy,and the trend of marketization.
