Analyzing the Hydrogen Supply Cost of Various Scenarios for A Blue Hydrogen Supply Chain Between Korea and Australia

Two scenarios were assumed to analyze the unit price of hydrogen implementation and build a blue hydrogen supply chain between Australia and Korea. Scenario 1 was the case of the unit price for transporting blue hydrogen produced at steam methane reforming (SMR) facilities in Australia to South Korea by three methods. Scenario 2 was the case of the unit price of hydrogen produced through domestic SMR facilities with CO2 sequestration in Korea and Australia, respectively. Considering the various implementations and the unit price depending on the technology level and process efficiency, Monte Carlo simulation was used to calculate the implementation unit prices statistically. For scenario 1, the results were $12.4/kgH2 (liquid hydrogen), $6.3/kgH2 (ammonia), and $13.8/kgH2 (liquid organic hydrogen carrier, LOHC). For scenario 2, they were $21.5/kgH2 (Australia) and $13.7/kgH2 (Korea), depending on CCS site location. This analysis showed that the implementation of blue hydrogen as ammonia in Australia is the most feasible option.
