Enapter AEM Electrolyser EL 2.1

Making Green Hydrogen Easy

Enapter’s patented anion exchange membrane (AEM) electrolyser is a standardized, stackable and flexible system to produce on-site hydrogen.

The modular design – paired with advanced software integration – allows set up in minutes and remote control and management. Stack this electrolyser to achieve the required hydrogen flowrate.


This version 2.1 is the predecessor model to EL 4.0.

Energy Management System (EMS)

Energy Management System:

Enapter’s unique Energy Management System (EMS) allows for intuitive monitoring and control of the electrolysers and dryers, as well as easy integration with third-party devices (ie. fuel cells, sensors, tanks, solar, wind, etc.).

The EMS takes energy system control software to a whole new level.
