Hysata, an electrolyser firm from Australia, has partnered with South Korean steelmaker POSCO to advance green hydrogen production technology. The collaboration involves two joint development agreements (JDAs) with POSCO Holdings and POSCO Eco & Challenge (E&C). Under the Holdings JDA, the focus will be on material research and development to jointly create materials and systems for the electrolysers. On the other hand, the E&C collaboration will concentrate on electrolyser construction. Hysata's innovative capillary-fed electrolyser technology eliminates the need for traditional liquid electrolyte reservoirs, improving efficiency significantly. This technology utilizes capillary action to deliver the electrolyte to the reaction sites, achieving an impressive electrical efficiency of 95% (41.5kWh/kg of hydrogen), which surpasses current commercial systems with efficiencies of 70-75%. The JDAs follow Hysata's successful securing of investment from POSCO Holdings and E&C earlier this year. The collaboration aims to leverage Hysata's groundbreaking technology along with POSCO Group's expertise in materials, system development, engineering, and construction. The partnership is expected to fast-track the development of Hysata's next-generation electrolyser technology, ultimately reducing the cost of hydrogen production and transforming the economics of green hydrogen. Dr. Juwoung Yoon, POSCO Holding's head of clean hydrogen research, emphasized that the joint development effort will accelerate global green hydrogen advancements and help decarbonize hard-to-abate sectors like steelmaking.
