Kawasaki Heavy Industries, Yanmar Energy Answer, and Japan Engine Company have efficiently performed the world’s first land-based operation of marine hydrogen engines. The demonstration came about at Japan Engine’s headquarters manufacturing facility, the place a newly put in liquefied hydrogen gasoline provide system was utilized.
Kawasaki Heavy Industries manufactured the brand new liquefied hydrogen gasoline provide system, that shops and gasifies liquid hydrogen, supplying it at each excessive and low strain to engines developed by the three firms. This permits testing throughout a variety of purposes, together with low-speed two-stroke primary propulsion engines, four-stroke auxiliary engines, and four-stroke primary generator engines for electrical propulsion ships.
Kawasaki Heavy Industries and Yanmar Energy Options efficiently demonstrated hydrogen combustion in medium-speed four-stroke engines, confirming secure operation at rated output, with the goal of reaching zero emissions. Growth will proceed to additional refine engine efficiency.
Japan Engine is progressing with the event of a low-speed two-stroke hydrogen engine, scheduled to start operation in Spring 2026.
A shared function of all three engines is the power to considerably scale back greenhouse fuel emissions whereas sustaining redundancy by way of a dual-fuel system that may change between hydrogen and diesel gasoline as wanted.
Following land-based demonstrations, the three firms plan to work with shipowners and shipyards to conduct onboard trials and transfer towards the sensible implementation.
The challenge is part of Inexperienced Innovation Fund Tasks / “Subsequent-Era Ship Growth” of the New Power and Industrial Expertise Growth Group (NEDO).
