Yanmar’s H2 fuel cell system approved in Japan

The approval granted by ClassNK marks a significant milestone for the burgeoning hydrogen segment in the country, and an extension of the market for Yanmar hydrogen fuel cell technology.

Zero-emission ships

The primary objective of Yanmar’s system is to advance the use of zero-emission ships in the maritime sector, effectively eliminating emissions such as CO2, NOX, SOX, PM, and others for both workboats and larger vessels.

Yanmar said that the design centres around ease of installation, with a configuration that seamlessly integrates key auxiliary components like gas valve units into the system housing.

Additionally, the system’s capability for parallel connection of multiple units and flexibility in adjusting the number of installed modules in its housing allow it to cater to diverse ship output requirements.

Both the system and its installed modules have successfully met the prescribed requirements for fuel cell power systems based on ClassNK’s “Guidelines for Fuel Cell Ships (2nd Edition).” This confirmation follows test results conducted in accordance with relevant standards.

Yanmar PT has already proposed this innovative system to a range of vessels, including passenger ships, workboats and cargo ships, that operate in coastal areas with access to hydrogen infrastructure.

It’s a development which marks a significant step towards sustainable and environmentally friendly maritime solutions in the segment.
