The Hydrogen Support Vessel developed by K-Challenge Racing & Lab was successfully refueled in Lorient, using a mobile hydrogen station, with FÉTIS Group companies (SECO MARINE / SECOM ENGINEERING) ensuring system integration throughout the operation.
The demonstration combined technical depth with stakeholder engagement. On board, the HSV showcased its configuration: two EODev REXH2 fuel cells of 80 kW each, fed by 32 kg of hydrogen stored at 350 bar across four type-IV tanks. The bunkering demonstration validated simultaneous dual-side refueling, confirming safety, efficiency, and readiness for operational deployment.
This first-of-its-kind operation in Brittany illustrates how collaboration between technology developers, system integrators, and operators can accelerate the decarbonization of fleets and ports.
