Honda, Kawasaki, Suzuki, and Yamaha have agreed to develop hydrogen combustion engines to decarbonize two-wheelers and other compact vehicles. This consortium will focus mainly on the research for the viability of this type of powertrain, with no production plans quite yet.

Japan’s four largest motorcycle manufacturers are looking into the viability of hydrogen combustion engines for two-wheelers to keep their famed combustion engines in use while still providing a zero-carbon solution. The decarbonization of motorcycles has mainly come from battery-electric drivetrains, such as the Harley-Davidson LiveWire One and Zero’s offerings.

Storage is the challenge

However, this partnership within the motorcycle industry is focusing on the early stages of development, with the goal mainly being the research of the possibilities in terms of high-pressure hydrogen storage in such a compact vehicle and its viability. Any further production plans are up to the manufacturers themselves.

Toyota will also join this organization, called the Hydrogen Small Mobility & Engine Technology Association, as an expert in hydrogen combustion engines, having developed several prototypes for racing and road use.

Hydrogen combustion engines would make sense on motorcycles, as they are often used as hobby vehicles, where the noise and vibrations are part of the experience. However, the collaborative organization also looks into small hydrogen combustion engines for other recreational vehicles, such as buggies, speedboats, and drones.
