Kawasaki Demonstrates Hydrogen Engine

Kawasaki proves there is an alternative to electric.

On July 20, 2024, Kawasaki Motors Ltd., a member of the Kawasaki Heavy Industries Group, conducted the world’s first public demonstration run of a hydrogen ICE (internal combustion engine) (by a mass-production motorcycle manufacturer) at Suzuka Circuit in Suzuka City, Mie Prefecture, Japan.

In this particular demonstration, Kawasaki packed their new hydrogen engine into a motorcycle chassis but the significance here extends well beyond a single vehicle-type. Government regulations for all engine-equipped vehicles and equipment are putting on the squeeze and, until now, most of the R&D has been going toward electric. Kawasaki realizes that there may be an even better alternative, one with far fewer compromises. Rather than just talk about it, they built it.

The hydrogen ICE motorcycle was designed and built as part of Kawasaki’s research that began in March 2023, with test runs starting this year, culminating in this public demonstration run during the Suzuka 8 Hours FIM World Endurance race. Powering the machine is a hydrogen engine based on the 998 cc In-Line Four Supercharged Engine found in Kawasaki’s Ninja H2 motorcycle, with modifications made to allow direct injection of hydrogen fuel into the cylinders. The motorcycle’s chassis was designed to accommodate hydrogen fuel canisters and a hydrogen fuel supply system on-board.

Hydrogen ICE operates on hydrogen combustion, delivering the rumble and pulsating sensation that riders love when twisting the throttle, while emitting mainly water and a very small amount of CO2.

As part of their carbon-neutral initiative, Kawasaki Motors is currently conducting research and development with the aim of achieving a functioning hydrogen ICE motorcycle as one carbon-neutral option for riders beginning in the early 2030s. Timing and availability may vary depending on the hydrogen fuel supply infrastructure and the status of legal regulations in each country.

Kawasaki Motors is a full member of HySE (Hydrogen Small mobility & Engine technology), a research association focused on hydrogen technology that is actively conducting basic research on hydrogen engines, hydrogen filling systems, and fuel supply systems in order to produce hydrogen-powered small mobility vehicles, including off-road.

We’re hoping this marks the beginning of a swing toward hydrogen engine development to offer future off-roaders an alternative to electric.
