H-TEC PEM Electrolyzers HCS

  • Cube system for large multi-MW PEM electrolysis plants
  • Closed container solution for outdoor installation or open skids for indoor installation
  • Optional water treatment and hydrogen purification

Multi-megawatt scale green hydrogen production

Modular, scalable, powerful: The H-TEC SYSTEMS Hydrogen Cube System (HCS) is a modular system, designed to realize large PEM electrolysis plants for producing green hydrogen. Multiple 2 MW Cubes can be combined to build up multi-MW plants. The Cubes are available as closed containers for outdoor use or as open skids for indoor installation. They are equipped with 18 H-TEC SYSTEMS S450 PEM Stacks, integrated process water treatment and an electrical power supply. Water and hydrogen purification units can be integrated optionally.
