绿氢产业链成本分析及发展路径研究OACHSSCD

This paper refines a cost estimation model for the green hydrogen industry chain and comprehensively discusses the future development pathways and trends of the green hydrogen industry based on various carriers and transportation modes for green hydrogen storage and delivery.The main conclusions include that the different cost of green hydrogen production across regions due to regional differences in renewable resource endowments and technological levels enables the interregional flow of green hydrogen resources,the green hydrogen industry chain based on pipeline transportation(with 20%hydrogen blending)holds an absolute cost advantage and the chain using green ammonia as a carrier exhibits a relative cost advantage,domestic and foreign green hydrogen compete with each other to a certain extent for green hydrogen imports,and Chinese green hydrogen is more competitive for green hydrogen exports and pathways using green ammonia and green methanol as carriers offer significant cost advantages.It proposes that the government should increase investment in the green hydrogen industry to expand production capacity,improve hydrogen infrastructure to promote industry chain collaboration,jointly establish international green hydrogen standards to monetize carbon reduction value,strengthen international cooperation on hydrogen resources to ensure supply chain security,and enhance international technological cooperation to boost industrial competitiveness.
