Fossil-Free Power


Yanmar Marine said it conducted a field demo of its hydrogen-powered fuel-cell system as the Japan-based manufacturer continues to develop technologies beyond diesel power.

The fuel-cell project was developed with Toyota and utilizes modules taken from the automaker’s Mirai vehicle. Installed in Yanmar’s EX38A FC test-bed boat, the polymer electrolyte fuel cell module produces 250kW, the equivalent of about 335 hp.


Yanmar’s green energy plan is aligned with the International Maritime Organization’s strategy to reduce greenhouse gas emissions to zero by the end of the century, the company said.

“Yanmar aims to verify specific issues and solutions in a maritime environment for deployment of the maritime fuel cell system,” the company said in a statement.

Yanmar said it will continue its testing and scale up by connecting multiple units, to be used to larger boats, during the next four years.
