Description Vendor

The RCT HyMax is an advanced hydrogen generation system utilizing alkaline electrolysis technology. It is designed for efficient and reliable hydrogen production with high purity (over 99.999%), offering scalability from small to large production capacities. The system features a modular architecture, combining an electrolyzer stack, gas-liquid separators, purification systems, and auxiliary units in one integrated solution. It operates at a pressure of 1.6 MPa and can produce hydrogen at rates of 200, 500, or 1000 Nm³/h, with industry-leading efficiency in converting electricity to hydrogen. The system is certified with IATF, CE, ASME, ATEX, and PED, ensuring compliance with international standards. It is suitable for both small and large-scale hydrogen production needs, with the ability to connect multiple modules for higher production capacities up to 20 MW.

Use Cases

  • Hydrogen production for industrial applications
  • Hydrogen generation for energy storage
  • Hydrogen production for fuel cell applications

Capabilities

  • Produces hydrogen via alkaline electrolysis
  • Supports hydrogen production capacities of 200, 500, or 1000 Nm³/h per single stack
  • Allows modular expansion for higher total production capacities
  • Operates at electrolyte temperatures between 85 and 92 °C
RCT GH GmbH RCT GH GmbH (RCT Hydrogen), founded in 2024 through a strategic alliance between RCT Holding (51% stake) and China's Jiangsu Guofu Hydrogen Energy Equipment (Guofuhee, 49% stake), is a hydrogen equipment manufacturer headquartered in Constance, Germany that began manufacturing electrolyser stacks in Saarbrucken, Germany in 2026, providing alkaline pressurized electrolyser technology aimed at supporting medium- and large-scale industrial hydrogen initiatives through a 'hydrogen-as-a-service' business model. The company launched operations at its new electrolyzer manufacturing facility in Saarbrucken as part of a joint venture with Bruck (a German manufacturer of forged and ring-rolled products), with the facility designed for a target annual production capacity of up to 250 MW, beginning production with the assembly of a 5 MW electrolyzer scheduled for delivery and commissioning at a German industrial site in 2026, with additional projects exceeding 30 MW of combined electrolysis capacity currently in development. RCT Hydrogen's integrated systems incorporate key components supplied by Chinese partner Guofuhee (operating through its German subsidiary GF Hydrogen Europe GmbH), with TUV-certified technology and a preliminary agreement signed for delivery of two 2.5 MW electrolyzer systems to industrial customers, positioning RCT to enable cost-effective and reliable green hydrogen production by transitioning to local European production and eliminating import dependence. As Dr. Peter Fath (founder) and Dr. Eric Ruland (Vice President Sales and Products) drive the company's vision of triggering a real hydrogen boom by enabling industrial hydrogen use at reasonable costs based on renewable-electricity-powered grids, RCT Hydrogen continues scaling its German-Chinese collaborative manufacturing model to advance the European green hydrogen equipment supply chain.
