Kawasaki, Suzuki, Honda, and Yamaha collaborate to develop hydrogen-powered engines for small mobility

Kawasaki, Suzuki, Honda, and Yamaha have announced their collaboration to develop hydrogen-powered engines for small mobility vehicles. The four manufacturers have received approval from Japan’s Ministry of Economy, Trade, and Industry (METI) to form a technological research association called HySE (Hydrogen Small mobility & Engine technology). While the specific mention of two-wheelers is not stated, the background of the companies involved and the reference to “small mobility” indicate a focus on two-wheelers.

Each company has been assigned a different role within the association. Honda will focus on model-based development of hydrogen-powered engines, Suzuki will conduct element studies on functionality, performance, and reliability, while Yamaha and Kawasaki will engage in hands-on research using real hydrogen-powered engines to assess their functionality, performance, and reliability. Additionally, Yamaha will study the requirements for hydrogen refueling systems and tanks, while Kawasaki Motors will investigate the auxiliary equipment needed for fuel supply systems and tanks.

In addition to the four full members, Kawasaki Heavy Industries and Toyota Motor Corporation will support the association as special members. Kawasaki Heavy Industries, being involved in the ‘CO2-free Hydrogen Energy Supply-chain Technology Research Association’ (HySTRA), will contribute its expertise to HySE’s activities. Toyota will leverage HySE’s research results for the development of hydrogen-powered engines, drawing on its knowledge and experience in designing large hydrogen-fueled power units for four-wheel vehicles.

The use of hydrogen as a fuel source presents technical challenges, including fast flame speed and limited fuel tank capacity. The members of HySE are committed to conducting fundamental research and utilizing their expertise in developing gasoline-powered engines to overcome these challenges. Their aim is to establish design standards for hydrogen-powered engines in small mobility vehicles and advance research in this area.

The collaboration between these Japanese automakers is driven by their shared mission to provide diverse and sustainable small mobility options, thereby contributing to the realization of a decarbonized society. Through HySE, they intend to deepen their collaborative relations and meet the evolving needs of users in the pursuit of a greener future.
