ClassNK AiP Yanmar Power Fuel Cell Tech

ClassNK, a leading classification society, has awarded its first Approval in Principle (AiP) for a maritime hydrogen fuel cell system developed by YANMAR Power Technology Co., Ltd. (YANMAR PT). This marks a significant milestone as the first AiP certification for a maritime hydrogen fuel cell system from a Japanese manufacturer.

Hydrogen fuel cells are gaining prominence as a potential solution to reduce greenhouse gas (GHG) emissions in the shipping industry. Recognizing the unique characteristics of hydrogen and ongoing safety discussions at the International Maritime Organization (IMO), ClassNK has issued the “Guidelines for Fuel Cell Power Systems On Board Ships (Second Edition).” These guidelines, based on IMO’s interim guidelines and relevant IEC standards, outline safety requirements for the design of ships using fuel cell power installations.

YANMAR PT’s maritime hydrogen fuel cell system (300kW) integrates key auxiliary components within the system enclosure, simplifying installation on ships. The system is designed to allow parallel connection of multiple units and adjustments to the number of hydrogen fuel cell modules, ensuring adaptability to various ship power output requirements.

ClassNK conducted a comprehensive review of the system in line with its guidelines, assessing required tests and risk factors. Having confirmed compliance with prescribed requirements, ClassNK issued the Approval in Principle.

As part of its commitment to advancing decarbonization initiatives, ClassNK will actively contribute to the industry’s broader decarbonization efforts. The society aims to incorporate knowledge gained through collaboration with industry pioneers into rules and guidelines, further supporting the maritime sector’s journey toward sustainability.
