Major Japanese motorcycle manufacturers Kawasaki, Yamaha, Honda, and Suzuki, along with car manufacturer Toyota, have joined forces to develop hydrogen internal combustion engines.
The collaboration, known as HySE (Hydrogen Small mobility & Engine technology), aims to explore alternatives to fossil fuels and drive advancements in hydrogen-powered mobility. With a focus on motorcycles and scooters, this initiative marks a significant step towards reducing emissions and achieving CO₂ neutrality in the transportation sector.
Kawasaki and Yamaha, the pioneering motorcycle manufacturers involved from the project’s inception, are prioritizing the development of hydrogen combustion engines. Honda and Suzuki have recently joined the collaboration, emphasizing the focus on smaller hydrogen engines for motorcycles and scooters. This collective effort signifies a commitment to integrating hydrogen technology into the realm of two-wheeled transportation, contributing to a more sustainable future.
Yamaha, in particular, has showcased its hydrogen engine technology with the introduction of the α live RX engine. Based on the renowned Yamaha CP3 triples, this in-line three-cylinder engine has been converted to hydrogen operation. The α live RX engine features an electric generator instead of a gearbox, enabling its use as a power generator or even a range extender for flying drones. With an impressive output of 88 kW (120 hp), Yamaha’s hydrogen triple has the potential to revolutionize hydrogen-powered motorcycles.
The partnership between Yamaha and Toyota further highlights the potential of hydrogen combustion engines. Yamaha has developed a hydrogen-compatible V8 engine with a 5-liter displacement for Toyota. Additionally, the Toyota Corolla H2 Concept, built with Yamaha’s support, participated in the 24-hour race at the Fuji International Speedway, showcasing the capabilities of hydrogen-powered vehicles. Such collaborations between motorcycle and car manufacturers signify the importance of cross-industry cooperation to accelerate the adoption of hydrogen technology.
Kawasaki Heavy Industries has been at the forefront of hydrogen research and development since 2010. Through its HySTRA initiative (Hydrogen Energy Supply-chain Technology Research Association), Kawasaki is actively involved in developing technologies for hydrogen production, transportation, and utilization across the entire supply chain. The company is currently conducting tests for large-scale hydrogen volume transports from Australia to Japan. Kawasaki’s hydrogen-powered gas turbines and plans for hydrogen engines in airplanes, ships, and two-wheelers demonstrate its commitment to advancing hydrogen infrastructure.
