The AEM string based Electrolyser meeting your needs
The many electrolyser cores of the AEM Nexus ensure optimum reliability and reactivity to fluctuating renewable energy at any load. Make up to 210 Nm3/h of green hydrogen an hour (450 kg/24 hours) with our 1 MW AEM Electrolyser – or start halfway with our 500 kW version. Both with 99.999% hydrogen purity.
This containerised electrolyser ofers you quick and straightforward setup so you can focus on making and using your green gas. Software control as well as simplified servicing with easily swappable electrolyser stacks streamline your operations.
AEM Stack electrolyser cores are the heart of our green hydrogen generators. Our AEM Nexus has hundreds, mounted in strings of 10. Each string ramps up or down separately to get the most out of your renewable energy at any load, delivering exceptional operational flexibility of 3-100%.
Resilience you can rely on: The modular design removes bottlenecks and single points of failure, all the way from AEM stacks to balance of plant. Enjoy maximum uptime, even when servicing: Work on afected strings of AEM Stacks while others still produce green hydrogen.
