A Series

Atmospheric Alkaline Electrolyser

150-3,880 Nm³/h

The world’s most energy efficient electrolysers, the A Series features a cell stack power consumption as low as 3.8 kWh/Nm3 of hydrogen gas produced, up to 2.2 MW per stack. A Series electrolysers can produce up to 3,880 Nm3/h of hydrogen or just over 8 ton per day. Our modular concept enables us to deliver customized indoor hydrogen solutions for any application, configuration and size – anywhere. Nel Hydrogen tailors each delivery to any customer requirement, from complete installation of the entire electrolyser plant, to delivery of specific modules according to customer preferences. This robust system can be containerized, offering one of the world’s smallest footprints for high capacity electrolyser plants at 200 barg.
