This achievement marks a significant step forward in the safe deployment of compact hydrogen-based energy solutions for the maritime sector. The AiP confirms that the system’s design aligns with BV rule note NR678 for hydrogen fuelled ships, offering a viable path for incorporating alternative fuel technologies into modern vessel architectures. 

The approved system is a hydrogen storage and supply solution developed to power fuel cells using compressed gaseous hydrogen stored in Type 4 tanks. Its design allows for integration into confined spaces located below deck, enabling new design opportunities for low-emission vessels.

These results were made possible through a dedicated R&D program focused on innovative risk reduction and mitigation measures, which led to the development of dedicated patented components with advanced safety functionalities, tailored for integration in demanding maritime environments.

A Type 4 hydrogen tank is a high-pressure storage vessel composed of a polymer liner fully wrapped in carbon fibre composite, designed to combine maximum strength with minimum weight — a key technology for hydrogen mobility.

Benoit Perrot, Leader Marine Hydrogen Projects, Seco Marine, said: “We would like to extend our congratulations to all teams and partners involved for their technical excellence and collaboration. Special recognition goes to *France 2030* and the *Pays de la Loire Region*, whose support has been instrumental in enabling this progress.“

Matthieu de Tugny, Executive Vice President, Bureau Veritas Marine & Offshore: “By supporting the development of innovative, compact, and robust hydrogen systems, we are helping pave the way for a more sustainable future for shipping. We are delighted to work alongside industry pioneers like SECO MARINE to accelerate the adoption of alternative fuels in line with global decarbonization goals.“
