HydroFlow Refuel is a hydrogen refueling station designed for dispensing compressed hydrogen to fuel cell electric vehicles. The system integrates a hydraulic-driven hydrogen compressor, hydrogen dispenser, chiller unit, accumulator storage, and safety systems within designated safety and hazardous areas. The compressor supports inlet pressures of 14–16 bar and discharge pressures up to 950 bar. The dispenser is designed for H35 and H70 refueling in accordance with SAE J2601-02, with a maximum flow rate below 3.6 kg/min and measurement accuracy of ≤ ±1.5 %. A chiller system maintains hydrogen outlet temperatures between 5 and 15 °C to support controlled refueling conditions.

Use Cases

  • Hydrogen refueling for fuel cell electric vehicles

Capabilities

  • Dispenses compressed hydrogen for vehicle refueling using H35 and H70 protocols
  • Supports hydrogen compression up to 950 bar
  • Controls hydrogen temperature during refueling using an integrated chiller
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.
