NH-X Series Electrolyser Systems

Advanced Alkaline Electrolyzers Purpose-Designed for Direct Connection with Renewables

Next Hydrogen’s X-Series systems redefine alkaline electrolysis. Our proprietary design integrates gas-liquid separation and independent fluid flow paths, delivering unmatched flexibility, superior efficiency, and dynamic response to harness renewable energy.

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 ​5% 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.
