“…At the same time, huge CO 2 emissions are stimulating the deployment of carbon capture, utilization and storage (CCUS) technology, which aims to reduce up to 90% of carbon emissions by implementing additional systems used for CO 2 recovery, transportation, and storage/utilization. 53,54 H 2 made from fossil fuels but coupled with the CCUS technology is considered blue hydrogen. 50 Fig.…”

“…For estimating H 2 production costs, the data of the base plant, which are organized in Table S1 for SMR-CCS and WE-RE, , are obtained from previous studies and adjusted for appropriate scales with the below eqs – for SMR-CCS and eqs – for WE-RE. Proton exchange membrane WE is considered for the WE system in this study, although alkaline WE is a mature technology, given that it is a commercialized technology and expected to be a mature technology by solving its challenges such as durability, the high expense for required novel materials and has many advantages including simplicity of balancing plants which makes it more attractive for industrial scales, high purity, low thickness, operating conditions, and compact design .…”

As deviations in H2 production capacity by countries become a considerable barrier to the realization of the global H2 economy, international trade between countries with abundant resources and those with limited resources is required. In line with this trend, numerous supply chains between several countries have been planned, and associated studies have been conducted. However, the study which treats international overseas H2 trade chains considering numerous major importing and exporting countries has rarely been conducted before. In this study, a comprehensive optimization for the overseas H2 supply chain considering the three major importing countries including Korea, Japan, and Germany was conducted with mixed-integer linear programming considering both economic and environmental aspects simultaneously. Through the optimization study, the most feasible H2 supply chains for each importing country could be verified according to years and case scenarios. Blue H2 from Qatar turns out to be the most feasible supply chain for Japan in 2030, while green H2 from South Africa is the most feasible one for other importing countries. In 2040, green H2 from South Africa and Australia becomes the best one for Asian importers, and Australia finally dominates all the supplies after 2050. In the case of Germany, green H2 from Spain is considered the best after 2040. Depending on the scenario, the difference in the selected countries and supply amounts is not significant, though the costs are varied. Ammonia turns out to be the most feasible carrier for H2, and the total cost including the carbon tax ranges from 2.15 to 3.43 $ kgH2 –1, which is a range from the current green H2 to the blue H2 price.

As environmental problems become serious, many countries have been striving to change fossil-based energy to renewable and sustainable hydrogen energy. However, there are large capacity differences for each country’s hydrogen production, making hydrogen trading necessary. Although extensive research has investigated hydrogen technologies and economics, to the best of our knowledge, no study has examined the optimization of the overall hydrogen supply chain, from overseas supply to domestic consumption, considering various feasibility scenarios. This is a case study on the hydrogen supply chain for South Korea, which is expected to be one of the major hydrogen-importing countries, considering the decarbonized hydrogen requirements of the importing country and the production capacities of exporting countries over two decades. This study’s optimized results for a hydrogen supply chain via mixed-integer linear programming reveal that it is most feasible for South Korea to import blue hydrogen from Qatar and Russia and green hydrogen from UAE and India, using liquefied hydrogen in the near term. This is because of the significantly lesser resource prices compared to other countries. The share of blue hydrogen supply dominates in the near term, while the green hydrogen supply is expected to gradually prevail over blue hydrogen due to an exponential drop in the renewable electricity price. With the price drop of green hydrogen, green hydrogen purchases from other countries in tandem with the UAE are predicted, rather than the blue hydrogen supply, considering that long-term demand will exceed the UAE’s predicted capacity.
