Yanmar, a renowned Japanese manufacturer with a legacy in diesel engine technology, has taken significant strides in advancing hydrogen fuel cell systems for maritime applications. This initiative underscores its commitment to innovation and environmental sustainability as part of a broader goal to achieve a carbon-neutral society.
Early Initiatives and Development
Yanmar’s exploration into hydrogen fuel cell technology began in 2015 with its participation in projects commissioned by Japan’s Ministry of Land, Infrastructure, Transport, and Tourism (MLIT). These initiatives focused on developing safety guidelines for hydrogen fuel cell ships, an essential step in integrating this clean energy technology into maritime operations. Collaborating with the National Maritime Research Institute and other industry partners, Yanmar conducted extensive research to address challenges unique to maritime environments, such as the effects of seawater immersion and vessel movement on hydrogen fuel cells.
Building on this foundational work, Yanmar developed a maritime hydrogen fuel cell system utilizing components from Toyota’s MIRAI fuel cell vehicle. Engineers from various Yanmar Group departments contributed their expertise in hull design, electrical systems, and control technologies. This collaborative effort culminated in a test boat equipped with hydrogen fuel cells, lithium-ion batteries, and an electric motor—all seamlessly integrated into a newly designed hull.
Demonstration and Testing
In March 2021, Yanmar launched demonstration tests for its hydrogen fuel cell-powered boat. These tests marked a milestone as they included the world’s first 70 MPa high-pressure hydrogen refueling of a moored vessel from a mobile hydrogen supply station. The demonstration boat, based on Yanmar’s EX38A pleasure boat, featured all major components installed below deck to preserve a pleasant interior.
The tests validated the system’s load-tracking performance, demonstrating the fuel cell system’s capability to maintain steady cruising performance under real-world conditions. Insights gained from these tests are being used to enhance the system’s commercial viability and to develop marine hydrogen refueling infrastructure.
Commercialization and Recent Developments
In August 2023, Yanmar Power Technology (YPT), a subsidiary of Yanmar Holdings, announced the commercialization of its maritime hydrogen fuel cell system. Designed for passenger vessels, workboats, and cargo ships operating in coastal areas, the system boasts a rated output of 300 kW and features a gas valve unit built into the housing for streamlined installation. Approval in Principle (AiP) from ClassNK, a Japanese classification society, underscores the system’s adherence to stringent safety and performance standards.
A significant milestone was achieved in November 2023 with the delivery of Yanmar’s first commercialized maritime hydrogen fuel cell system to the passenger ship HANARIA. Operated by MOTENA-Sea, this hybrid vessel uses both hydrogen and biodiesel to power its onboard electric propulsion system. When operating solely on the hydrogen fuel cell system and batteries, the ship achieves zero emissions, offering a quieter, more environmentally friendly experience.
Future Outlook and Commitment to Sustainability
Yanmar’s advancements align with its “YANMAR GREEN CHALLENGE 2050” initiative, which aims to address greenhouse gas reduction and minimize environmental impact. The company envisions deploying its hydrogen fuel cell systems across various ship types, including passenger ships, workboats, and cargo vessels. Leveraging its marine engine expertise, Yanmar plans to provide integrated solutions encompassing power storage, power management, propulsion systems, and hydrogen storage.
By continuing to innovate and collaborate with industry stakeholders, Yanmar is well-positioned to play a pivotal role in advancing clean energy solutions within the maritime sector. Its journey exemplifies a commitment to sustainability, innovation, and environmental stewardship.
