Abstract

This study develops a corridor-specific techno-economic framework for LOHC-based hydrogen export from Australia to Japan and applies it to four representative carrier systems: toluene/methylcyclohexane (TOL/MCH), dibenzyltoluene/perhydrodibenzyltoluene (H₀-DBT/H₁₈-DBT), N-ethylcarbazole/perhydro-N-ethylcarbazole (H₀-NEC/H₁₂-NEC), and benzene/cyclohexane (BZ/CH). The framework integrates carrier-specific process simulation, maritime logistics, regional cost assumptions, heat-supply options, and deployability factors within a unified hydrogen-to-hydrogen supply chain boundary. The results show that hydrogen production is the dominant cost driver, while carrier choice strongly affects salable hydrogen output, dehydrogenation energy demand, and noncost feasibility. Under the base-case configuration, in which dehydrogenation heat is supplied by combusting a portion of the produced hydrogen, the delivered levelized cost of hydrogen (LC_H2) ranges from 16.42 to 24.99 A$/kg-H₂, with BZ/CH achieving the lowest cost (16.42 A$/kg-H₂) while TOL/MCH represents the highest-cost option (24.99 A$/kg-H₂). An alternative biomass combustion heat source lowers LC_H2 for all carriers and changes the ranking by making TOL/MCH the second-lowest-cost option (14.30 A$/kg-H₂), while BZ/CH remains the lowest-cost system (12.41 A$/kg-H₂) and H₀-NEC/H₁₂-NEC becomes the highest-cost option (19.05 A$/kg-H₂). H₀-DBT/H₁₈-DBT provides a more balanced combination of cost, technical maturity, safety, and commercial deployability.

澳大利亚向日本出口lohc制氢的技术经济评价

本研究为澳大利亚向日本出口lohc基氢建立了一个走廊型技术经济框架，并将其应用于四种具有代表性的载体体系：甲苯/甲基环己烷（TOL/MCH）、二苄基甲苯/过氢二苄基甲苯（H0-DBT/H18-DBT）、n -乙基咔唑/过氢- n -乙基咔唑（H0-NEC/H12-NEC）和苯/环己烷（BZ/CH）。该框架在统一的氢到氢供应链边界内集成了特定于航母的过程模拟、海上物流、区域成本假设、供热选择和可部署性因素。结果表明，氢气生产是主要的成本驱动因素，而载体选择强烈影响可销售氢产量、脱氢能源需求和非成本可行性。在基本情况下，脱氢热通过燃烧产生的一部分氢气来提供，氢气（LCH2）的交付平准化成本范围为16.42至24.99澳元/kg-H2，其中BZ/CH的成本最低（16.42澳元/kg-H2），而TOL/MCH的成本最高（24.99澳元/kg-H2）。替代生物质燃烧热源降低了所有载体的LCH2，并改变了排名，使TOL/MCH成为第二低成本的选择（14.30 A$/kg-H2），而BZ/CH仍然是成本最低的系统（12.41 A$/kg-H2）， H0-NEC/H12-NEC成为最高的系统（19.05 A$/kg-H2）。H0-DBT/H18-DBT在成本、技术成熟度、安全性和商业可部署性方面提供了更加平衡的组合。

期刊介绍： Energy & Fuels publishes reports of research in the technical area defined by the intersection of the disciplines of chemistry and chemical engineering and the application domain of non-nuclear energy and fuels. This includes research directed at the formation of, exploration for, and production of fossil fuels and biomass; the properties and structure or molecular composition of both raw fuels and refined products; the chemistry involved in the processing and utilization of fuels; fuel cells and their applications; and the analytical and instrumental techniques used in investigations of the foregoing areas.
