GHS Co., Ltd. (GHS) participated in ‘H2 MEET 2024’ at KINTEX, Goyang, from September 25 (Wednesday) to 27 (Friday).
Established in 2022 as a research-driven company under Kumoh National Institute of Technology, GHS specializes in green hydrogen energy technology. The company focuses on accelerating the transition to environmentally friendly and sustainable energy by adopting Proton Exchange Membrane (PEM) and Anion Exchange Membrane (AEM) electrolysis technology for water electrolysis systems.
AEM technology, in particular, combines the advantages of conventional alkaline and cation exchange membrane electrolysis technologies, making it a promising next-generation hydrogen production method that is expected to replace existing technologies soon.
GHS explained, “To enhance the performance reliability of anion exchange electrolysis systems while reducing the manufacturing cost of key components, we aim to achieve a 20-30% reduction in hydrogen production costs compared to existing technologies. We are actively engaging in various government projects to localize hydrogen system materials and components in Korea. We are collaborating strategically with Phoenix Tech, an electronic components manufacturer, and S&J Tech, our joint technology development partner.”
The company also focuses on developing small-to-medium PEMWE (Proton Exchange Membrane Water Electrolyzer) and AEMWE (Anion Exchange Membrane Water Electrolyzer) modules directly connected to solar cells and their key components. This approach offers higher efficiency and lower costs than traditional large-scale hydrogen production systems linked with remote power grids.
The Membrane Electrode Assembly (MEA) showcased at the exhibition comprises three components: an ion exchange membrane, a catalyst layer, and a gas diffusion layer. GHS aims to improve the reliability of MEA and bipolar plate degradation while utilizing non-precious metal catalyst electrodes to develop a unique approach to stack and component design. This effort seeks to significantly reduce system manufacturing and operating costs compared to existing technologies.
The 10-100kW AEM/PEM electrolyzers use ion exchange membranes with anodes and cathodes as cores. Their reliability is reflected in an LHV H2 efficiency of 71.4%. The company aims to demonstrate promising hydrogen production efficiency by developing electrolysis technology at high current levels with low operating voltage (AEM).
H2 MEET is a specialized hydrogen industry exhibition for Korean and international companies and institutions involved in hydrogen production, storage, transportation, and utilization. From this year, H2 MEET aims to become a professional event that will enhance participation from global hydrogen industry companies, generate tangible results, and contribute to understanding South Korea’s hydrogen economy ecosystem. Starting this year, it will be held in conjunction with H2WORLD and concurrently with the K-BATTERY SHOW 2024 and HARFKO (Heating Air Conditioning Refrigeration and Fluid Exhibition—Korea) 2024 at KINTEX 1.
