Large Scale H2 Plants

Whether you need large quantities of hydrogen for industrial purposes, or utilization of excess renewable energy for energy storage – we have experience in both fields!

Nel Hydrogen is the acknowledged specialist in large scale electrolyser plants. The very nature of the A Series is seamless capacity upsizing from medium to large scale H₂ plants based on water electrolyser technology.

Our experience in large scale plants is exemplified through historical plants exceeding 30,000 Nm³/h, as well as the recent installation of new plants with an energy capacity of more than 60 MW.
