The push towards eco-friendly transportation isn’t just for carmakers; bike manufacturers are also jumping on the green bandwagon. 

A recent example is the debut of the world’s first hydrogen-ICE (internal combustion engine) motorcycle by Kawasaki Motors, showcased on July 20th at Japan’s Suzuka Circuit.

Kawasaki introduced the hydrogen-fueled Ninja H2 engine in October 2021, followed by concept sketches in November 2022, and unveiled the prototype in December 2023. 

The hydrogen engine is based on the 998 cc In-Line Four Supercharged Engine from the Ninja H2, modified to allow direct injection of hydrogen fuel into the cylinders. The bike’s chassis was redesigned to fit hydrogen fuel canisters and a hydrogen fuel supply system.

Hydrogen ICE motorcycles work by burning hydrogen, offering the familiar rumble and sensation that riders love while emitting mainly water and a tiny amount of CO2. According to Kawasaki, hydrogen burns faster and operates over a wider temperature range than petrol, making it more responsive.

Kawasaki is aiming to develop a fully functional hydrogen ICE motorcycle as part of its carbon-neutral initiative, targeting the early 2030s for availability. However, this will depend on the development of hydrogen fuel infrastructure and legal regulations in each country.

On top of that, Kawasaki Motors, along with other major Japanese motorcycle manufacturers such as Honda, Suzuki, and Yamaha, is part of HySE (Hydrogen Small Mobility & Engine Technology). 

This research association is focused on advancing hydrogen technology and developing hydrogen-powered engines for small mobility vehicles. 

They are undertaking fundamental research on hydrogen engines, filling systems, and fuel supply systems to produce hydrogen-powered small mobility vehicles, including motorcycles.
