Green Hydrogen Systems is a leading provider of standardised and modular electrolysers for the production of green hydrogen solely based on renewable energy. With its wide range of possible applications, green hydrogen plays a key role in the ongoing fundamental shift in our energy systems towards a net-zero emission society in 2050. As a result, the demand for green hydrogen is surging, requiring a significant scale-up of electrolysis capacity. 

Green Hydrogen Systems combines ultra-efficient, standardised and modular electrolysis technology with an on-site production approach to bring cost-competitive green hydrogen to producers of hydrogen fueling stations, those requiring hydrogen in power-to-X installations, industrial facilities and more. Our technology is already in use in several places in Europe, with the rapidly emerging OEM segment as a particular focus of future growth. Founded in 2007 and building on more than 10 years of technology development, we today have a commercially proven and cost-competitive electrolysis technology, endorsed by leading energy companies.
