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 20 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.
From containers to mega plants
The cost efficiency, reliability and flexibility of our technology are well established through nearly 1000 installations, in more than 50 countries across the world. We construct hydrogen plants of all sizes and configurations – from containers to mega plants. Largest installation to date: 135 MW, with a production capacity of 30 000 Nm3 H2 per hour. In fact, we can build as large as you wish.

Capturing excess renewable energy
Our hydrogen technology is the solution for intermediate storage of surplus energy from solar and wind power, to ensure stable delivery of electricity at demand. This way we increase and secure the value of your electrons. 24/7 hydrogen storage is possible, when flexing between solar/wind and grid. You may sell excess solar/wind energy to grid, depending on your local infrastructure. Renewable hydrogen plants can also be installed fully or partly off grid.
24/7 production flexes between solar/wind and grid, possible to sell excess solar/wind to grid.
24/7 production flexes between solar/wind and grid.
Partly off grid
Production directly connected to solar/wind, auxiliary system powered by the grid.
Full off grid
Entire system off grid.
