South Korean Innovation Makes Hydrogen Affordable in the Netherlands
Amsterdam, Friday, 3 October 2025.
South Korea’s new hydrogen system achieves over 83% efficiency, operating for 3,000 hours continuously, offering a viable alternative to natural gas and supporting the Netherlands’ green energy goals.
Record-Breaking Efficiency and Stability
The Korea Institute of Machinery and Materials (KIMM), a part of the National Research Council of Science and Technology, has developed an innovative 20 kW anode-supported Solid Oxide Electrolysis Cell (SOEC) system. This system has achieved a remarkable electrical efficiency of over 83%, operating continuously for more than 3,000 hours. This achievement sets a new standard for SOEC technology in South Korea, showcasing not only the system’s efficiency but also its stability under industrial conditions [1].
Cost-Effective Hydrogen Production
This breakthrough in hydrogen production technology is particularly significant as it offers a 25% reduction in production costs compared to conventional methods, especially when using affordable electricity from renewable or nuclear sources. The system consumes 15% less electricity than traditional alkaline or PEM electrolysis, thereby making hydrogen production more cost-effective and environmentally friendly. Such advancements are crucial for transitioning to a hydrogen economy and achieving carbon neutrality [1].
Impact on the Netherlands’ Green Transition
The Netherlands, striving to enhance its green energy initiatives, stands to benefit significantly from this technological advancement. With the increasing need to reduce dependency on fossil fuels, the affordable hydrogen produced by KIMM’s system could play a key role in the Dutch energy transition. The system’s ability to run efficiently and cost-effectively aligns well with the Netherlands’ goals of achieving a more sustainable energy infrastructure [1].
Looking Ahead: Future Developments
KIMM is now focused on developing the next generation of SOEC systems, aiming for efficiencies exceeding 85%. These future systems will integrate AI-driven diagnostics to optimize performance and reliability on an industrial scale. Such advancements promise to further decrease hydrogen production costs, making sustainable hydrogen a more accessible energy source globally. This ongoing innovation underscores the potential of hydrogen as a cornerstone of future energy systems [1].
