Alkaline Electrolysis

Hygreen’s alkaline electrolysis is a robust and well proven technology, with hundreds of products in use by customers worldwide. With projects reaching Megawatt and Gigawatt levels, alkaline is by far the most proven technology for hydrogen production at an increasingly greater scale.

  • High durability
  • Cost efficient
  • Suitable for large-scale output

PEM Electrolysis

PEM (Proton-exchange-membrane) electrolysis is well suited in applications where there are greater variabilities to operation and smaller output. Our PEM electrolyzer solutions currently range from 5 to 300 Nm³/h per stack, as we continue to develop stacks producing at 400 Nm³/h and more in the coming years.

  • High efficiency
  • Rapid response time
  • Compact configurations

AEM Electrolysis

Hygreen’s anion-exchange membrane (AEM) electrolyzer solutions are turnkey systems for hydrogen production, offering an optimal combination of efficiency, stability and ease of operation. Precision-designed with extensive testing in our R&D labs, Hygreen’s AEM systems are customizable for up to 100 Nm³/h (500 kW) of hydrogen, and suitable for a wide variety of smaller scale applications.

  • Flexibility for intermittency
  • Greater impurity tolerance
  • New promising technology
