STOFF2 GmbH is developing a new form of electrolysis technology for industrial applications of green hydrogen: Zinc Intermediate Electrolysis (Zink-Zwischenschritt-Elektrolyseur in German, ZZE). ZZE’s inherent energy storage function, hybrid hydrogen and electricity output, and high efficiency make it the ideal technology to decarbonize industrial processes. A single ZZE device can replace a traditional system consisting of an electrolyzer, compressor, storage tank, and battery.
