H-TEC PEM Electrolyzer HCS: H-TEC SYSTEMS products

H-TEC PEM Electrolyzer 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 for scaling up industrial green hydrogen production. HCS consists of 2 MW Cubes which can be combined into multi-MW plants with an electrolysis capacity of 4 – 10 MW or more. Each Cube represents a complete solution with integrated process water treatment system and electrical power supply, ready for outdoor operation. Optionally, the system can be equipped with fresh water or hydrogen treatment, as well as process heat recovery. Our flexible service offering ensures reliable operation and high plant availability. Proven proprietary PEM stack technology, efficient balance of plant design and high availability of spare parts make H-TEC SYSTEMS PEM electrolyzer HCS reliable and ready for the future.
