Yanmar Power Technology (Yanmar PT), a subsidiary of the Japanese group Yanmar Holdings, recently received an Approval in Principle (AiP) from the Norwegian classification society DNV for its GH320FC marine hydrogen fuel cell system.

This recognition marks a significant step forward in the integration of hydrogen technologies in the maritime sector, particularly in Europe.

A modular, adaptable system

The GH320FC stands out for its innovative design, making it easy to install on various types of vessel. Its modularity means that several units can be connected in parallel and the number of fuel cell modules can be adjusted, offering the flexibility to meet different energy needs depending on the type of ship and its operations.
 

Targeted applications

This system is particularly well suited to coastal ferries, river transport vessels, port service vessels and operations in low or zero emission zones, notably in Europe. It meets the growing requirements for reducing polluting emissions in the maritime sector.
 

European experience and ambitions

Building on its experience with previous installations, such as a coastal ferry currently in service in Japan, Yanmar PT plans to offer its hydrogen solutions to European customers. This approach is part of a desire to contribute to the maritime sector's decarbonisation objectives.
 

Recognition by DNV

Olaf Drews, Head of Engines and Pressure Equipment at DNV Maritime, underlined the importance of fuel cells combined with clean renewable fuels as an efficient and scalable solution for achieving zero-emission maritime operations. He expressed DNV's satisfaction in awarding this AiP to Yanmar and in working with a forward-looking company to prepare the next generation of ships.
 

Regulatory context and government initiatives

In early 2025, Yanmar PT received approval from the Japanese government for its plan to produce hydrogen-powered engines and fuel cell systems.

This approval is part of the project to promote the construction of zero-emission ships, supported by Japan's Ministry of the Environment and Ministry of Land, Infrastructure, Transport and Tourism. This project aims to encourage the construction of ships using alternative fuels such as ammonia and hydrogen.
 

Future prospects and commitments

Yanmar PT plans to restructure its activities into two separate entities by October 2025, one focusing on industrial engines and the other specialising in high-power products. The aim of this reorganisation is to enhance operational efficiency and better respond to specific market needs.

In conclusion, Yanmar PT's award of the AiP for the GH320FC represents a major step forward in the adoption of clean technologies in the marine sector. Thanks to its modular design, flexible installation and ability to adapt to a variety of energy needs, this hydrogen fuel cell system is a promising solution for decarbonising maritime activities.
