SunGreenH2 unlocks the production of affordable green hydrogen through its hyper-efficient, proprietary electrodes, which make the water electrolysis process more efficient, sustainable and less costly. SunGreenH2 manufactures core components - cells, stacks, and systems - involved in the electrolysis process, which can be utilised by all different green hydrogen producers, including Alkaline, PEM, AEM, membrane-free electrolyzer OEMs. Their core technology involves replacing existing cell components, which typically use expensive materials like platinum, iridium and titanium coated with gold, with low-cost and earth-abundant materials utilising their proprietary high-performance coating. This results in 200% green hydrogen production, 50% decreased stack CAPEX, 10% lower energy consumption, and 30x reduced expensive precious metals usage. While their core innovation applies at the cell level of the electrolyzer, which is the building block for the whole system, SunGreenH2 also produces the full stacks and electrolyzer systems for AEM technology as well, utilising design innovation to reap further efficiencies. Their solution is plug-and-play, meaning it can be utilised in any existing manufacturing process. SunGreenH2’s entire technology platform is under patent-protection and has been under development for the past 10 years. With the technology ready to go, the company is currently undergoing rapid commercialization as they establish a manufacturing and R&D facility in Australia to manufacture their products for customers across the globe.

Notable Achievements

  • Technology doubles (2x) hydrogen production at 50% of the original cost. 30x reduced use of platinum group metals. 10% lower energy usage.
