Toyota Mirai Hits the Water as Powertrain for a Yanmar Fuel-Cell Boat

Equipped with some high-pressure hydrogen tanks from the hydrogen fuel cell car Mirai, Toyota's new emission-free boat concept is designed for "superior range".
Toyota has a long history of working with the Japanese company Yanmar on watercraft, including the 2016 PONAM-28V.
At the moment, the H2 boat is just a concept, but Yanmar says that this type of ship would be well suited to moving tourists around in urban areas.
One of the most obvious effects of climate change is an increase in sea level. It therefore makes sense that at least some seagoing vessels are developed that do not emit carbon dioxide into the atmosphere and therefore increase these values ​​even further. In the hull of a new boat from Yanmar Holdings you will find an example of environmentally friendly boat technology. The boat's hydrogen-powered fuel cell system uses parts from the Toyota Mirai's powertrain.
Yanmar announced its new boat as part of a memorandum of understanding that the company signed with Toyota. The mission is to "develop a hydrogen fuel cell system for maritime applications". Toyota's contribution includes the high pressure hydrogen tanks used in the Mirai. Yanmar wants to develop an H2 drivetrain that is easy to install and has a "superior range". That seems familiar to me.

Yanmar hopes to install this maritime fuel cell system on its own boat so that it can begin field demonstration testing by the end of 2020 and then expand hydrogen technology "for a variety of applications and uses".

This is not Yanmar's first foray into hydrogen powered boats. In 2018, the company partnered with Toyota Tsusho, a member of the Toyota Group, and Ballard Power Systems to test a 16.5-meter H2-powered boat called Shimpo on site. The boat used a 60 kW hydrogen fuel cell system and a 60.0 kWh lithium ion battery system developed by the Uzushio Electric Company. The project was part of the 2015 project by the Japanese Ministry of Land, Infrastructure, Transport and Tourism to create a hydrogen-based society. Yanmar said in 2018 that a potential market for its first hydrogen ships could be sightseeing boats sailing on urban waterways, and that it "will continue to work with government, industry, and science to develop boats and ships using hydrogen fuel cells." This year, the lower greenhouse gas boats were said to be in line with the International Maritime Organization's strategy of zeroing boat greenhouse gas emissions by the end of the century.

Earlier this year, Toyota announced that a maritime version of the Mirai's powertrain would be used in the Energy Observer, a 31-meter renewable energy ocean-going vessel that can produce its own hydrogen using sea water. The adaptation of the fuel cell system to work on the water took only seven months at the Toyota Technical Center Europe and required a redesign of the system to reduce the size of the system.
Toyota started thinking about building boats in 1989. The automaker opened its Marine Business Planning Office in 1990 to work on pleasure boats and started selling its Ponam-28 in 1998. Other Toyota boats, including the Ponam-37 and Epic X22, went on after that, Toyota announced its new premium sport cruiser, the Ponam-28V, which was developed in collaboration with Yanmar.
