“…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 . Here, as presented in Table S1, the cost exponents( n ) for the SMR-CCS plant and WE-RE are considered to be 0.66 and 1, respectively, given that the exponent for SMRs is typically about 0.66, while that of a plant whose scaling up is accomplished by simply adding units such as electrolysis is close to 1 …”

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.

“…Foremost, largescale storage is needed to strengthen the flexibility and resilience of the energy system, which can help reduce costs [29]. However, "reliable, safe, effective, and efficient" storage solutions are yet to be established [217]. At the outset, there are significant cost barriers to overcome, given that storage may contribute 24%-35% of CAPEX for a blue hydrogen production plant [177].…”

Currently, the cost of electricity for electrolysis of producing hydrogen is about 70−90% of the total cost. Scientists predict that the share of renewable energy in total energy is expected to reach about 70% in 2050, as the cost of wind photovoltaic power generation in China is as low as 0.13¥/(kW•h), and that the use of renewable energy sources, mainly photovoltaic and wind power, of producing hydrogen can effectively reduce the cost of electricity. Meanwhile, with the improvement of technology, the cost of an electrolyzer used in proton exchange membrane hydrogen production technology can be reduced by about 50%, which will reduce the cost of hydrogen production by more than 20%. According to the distribution of electricity resources in each region of China, the project construction of renewable energy power generation and proton exchange membrane hydrogen production can be reasonably carried out. A long-distance hydrogen transmission system can be established to provide guaranty for the establishment and operation of urban hydrogen power stations using a combination of renewable energy and long-distance hydrogen transmission systems. This paper provides a reference for the industrial development and policy direction of hydrogen production by water electrolysis.
