K-Challenge Lab and Delavergne Shipyard are collaborating to create a hydrogen-powered professional vessel, a step towards decarbonizing maritime operations. The 12-meter aluminium workboat, with sea trials set for summer 2026 in Lorient, aims for commercial deployment later that year.

The partnership focuses on a fully integrated hydrogen propulsion system, including on-board power generation, secure storage, and a mobile refueling station. Delavergne Shipyard will construct the vessel based on its Exocet 10 platform. The project addresses technical and operational barriers to hydrogen adoption in the maritime sector.
