Yanmar launches hydrogen-powered fuel cell trials
Toyota fuel cell technology is powering a test boat that will explore commercial applicationsJapanese marine engine maker Yanmar has launched a screw-driven boat fitted with technology borrowed from Toyota’s Mirai hydrogen fuel cell passenger car.
The 7.9-tonne, 12.4-metre recreational boat, powered using a 250kW system featuring a twin-module Toyota Mirai fuel cell and turning a single screw, had its first field test yesterday.
The aim of the trial is to identify any issues with the technology as it is adapted for the water, with its release scheduled for 2025.
The system will also test how it can scale by hooking up extra fuel cells and batteries so it can power larger and heavier vessels.
No details were released on how the testing went. Yanmar is the first company in Japan to have its fuel cell unit approved for maritime applications.
Meanwhile, Yanmar has stepped up its push into the watersports market by banding with the World Wake Association to promote international events.
Yanmar has been working on providing a diesel engine that can power wake, surf and ski boats, but it is believed the hydrogen fuel cell technology could also adapt to this application.
US watersports brand Nautique is the first manufacturer to sign up to the diesel engine option, with the alternative drivetrain available on its 2021 model year Super Air Nautique G23 and G25 wake series of boats.
