Yanmar Power Technology Co Ltd (YPT), a subsidiary of Yanmar Holdings, has successfully commercialized a maritime hydrogen fuel cell system to decarbonize the maritime industry. The company plans to propose installing this system into various ships, including passenger ships, work ships, and cargo ships operating in coastal areas where hydrogen refueling is relatively accessible.
The maritime sector is pursuing decarbonization efforts in line with the International Maritime Organization’s (IMO) revised target of achieving net zero greenhouse gas (GHG) emissions by around 2050. YPT has actively participated in the Ministry of Land, Infrastructure, Transport, and Tourism’s (MLIT) initiatives to establish safety guidelines for hydrogen fuel cell ships and develop a roadmap for hydrogen utilization in the marine industry.
Furthermore, YPT has engaged in multiple initiatives, including navigational tests of demonstration ships equipped with hydrogen fuel cells and conducting high-pressure hydrogen refueling tests for ships. Leveraging its expertise and experience in the marine engine business, YPT aims to provide total solutions for the decarbonization and digitalization of ships with comprehensive designs covering the entire powertrain of fuel cell ships, encompassing power storage, power management, propulsion, hydrogen storage systems, and more. This complete system will support the decarbonization and digitalization of the entire ship.
As part of the Yanmar Group’s commitment to its Yanmar Green Challenge 2050 initiative, the company aims to realize a sustainable society while addressing GHG reduction and minimizing environmental impact. By delivering customized solutions that meet customer needs, YPT strives to contribute to solving society’s challenges.
Absolutely zero emissions
With a rated output of 300kW (customizable), the fuel cell system uses hydrogen ISO14687 type I, Grade D, which produces absolutely no emissions of carbon dioxide, nitrogen oxide, sulfur oxides, and particulate matter. Additionally, the system generates low vibration, noise, and no exhaust gas odor. A gas valve unit has been built into the system housing for easy installation into ships.
With beginnings in Osaka, Japan, in 1912, YPT was the first to make a compact, usable diesel engine in 1933. (Story and photos courtesy of YPT)
