A research team in South Korea has unveiled an energy system model, the KIER-TIMES, designed to assess hydrogen energy's pivotal role in the nation's 2050 Carbon Neutrality Scenario. Hydrogen is deemed crucial for achieving carbon neutrality, with potential as a clean energy source and a means to balance power grid operations. The team's analysis using the model suggests a need for 27% hydrogen energy in the national energy supply, with an expected rise to 25% in overall energy use. The study contemplates import strategies for hydrogen, emphasizing the necessity of at least 76% import share for carbon neutrality. It also delves into enhancing water electrolysis efficiency, targeting a 94% efficiency to reduce power and hydrogen consumption. Additionally, the research advocates for utilizing carbon capture technology in blue hydrogen production to streamline carbon neutrality efforts. Dr. Sang Yong Park, leading the research, highlights the significance of aligning hydrogen strategy with Korea's energy landscape, aiming to expand the model's analysis into sector coupling technologies. The project, part of the SCI Convergence Research Group, underlines the importance of international standards in deriving optimal hydrogen utilization strategies. Published in Energy, the findings mark a substantial step towards Korea's carbon neutrality goals.
