C-Range

The re-designed robust, containerised electrolyser solution. Offering the world’s smallest footprint for high capacity electrolyser plants at 200 bar.

Atmospheric Alkaline Electrolyser

A-Range – Tailored Solutions

The Nel A-Range represents the most reliable and efficient electrolysers in the world. Our modular concept enables us to deliver customised indoor hydrogen solutions for any application, configuration and size – anywhere. Nel tailors each delivery to any customer requirement, from complete installation of the entire electrolyser plant, to delivery of specific modules according to customer preferences.

Unlimited possibilities

Quick start-up and shut-down allow Nel A Electrolysers to produce H2 on-demand. The production is automatically controlled and offers a wide operational range from 15% to 100% of the installed capacity. This high flexibility ensures an ideal balance between hydrogen demand and production. For installations optimised for solar/wind, power-to-power, the operational range typically span from 0% to 100%.

All our three models are designed for future capacity expansions.

Reliable, cost efficient H2 supply

Gain independence with our on-site electrolyser plant. You are in control of your own supply of hydrogen. The most proven and robust electrolyser technology available ensure reliable and continuous production at all times. We provide sustained automatic production for years, with no need for maintenance shutdown (cell stack replacement to be expected after typically 8-10 years of operation).

Our advanced PLC control system provides smooth, unattended and automatic operation of the plant. Adding high efficiency and little maintenance with insignificant labour needs, Nel A-range truly offers the lowest operational costs available.
