NH-X Series Electrolyser Systems

Next Hydrogen’s Breakthrough Cell Design

We achieved the first breakthrough in cell architecture in decades, implementing an innovative design that integrates gas-liquid separation, removing restrictions and setting the stage for cost-effective and scalable green hydrogen production.

  • Internal gas-liquid separators in each half cell.
  • Fluid flow is maintained separate in each half-cell plate.
  • Superior dynamic response with no fluid restrictions.

Next-Generation Breakthrough Technology

High Current Density

Up to 4× current density enables 4x more hydrogen produced, while using the same raw materials and 1/3 the footprint of traditional alkaline systems.

Superior Dynamic Response

Our design enables 10% per second ramp up/down and a wide ​10% to 100% turndown range, effectively load-following variable renewable energy sources.

Best Commercially
Available Cell Performance

Next Hydrogen’s electrolysers exceed U.S. DOE cell performance targets providing operating cost savings.

Simplified
Balance of Plant

Eliminates bulky, costly external gas-liquid separator skids, simplifying balance-of-plant and reducing cost and footprint.

Flexible Green Hydrogen
Production at Scale

The NH-X Series is a scalable modular system capable of delivering multi-megawatts hydrogen production with unprecedented efficiency and flexibility. It is capable of directly harnessing renewable energy sources, producing green hydrogen for mobility and industrial applications economically and at scale.
